Description

Water treatment apparatus using microbubbles

The present invention relates to a water treatment device that purifies polluted water by using microbubbles to float and remove foreign substances in water, and more specifically, to a water treatment device using microbubbles in which water treatment efficiency is improved by clearly distinguishing between treated water from which foreign substances have been removed and scum.

In general, water can be classified into various types depending on its intended use, such as drinking water, agricultural water, or industrial water. Among these, especially in the case of drinking water or water for washing, which are closely related to human life, maintaining its cleanliness is the most important.

If the water used for drinking or washing/facial washing is not clean, the chances of contracting various diseases such as stomachache, diarrhea, and vomiting due to many invisible germs can increase.

To prevent the occurrence of these diseases in advance, various filters such as activated carbon filters, micro filters, and membrane filters were used to filter out foreign substances contained in raw water, or ultraviolet (UV) lamps were used to sterilize/treat bacteria such as E. coli contained in water, allowing water to be used with confidence.

Ultraviolet rays have a wavelength of 200 to 400 nm, which is just adjacent to the violet end of visible light. They are shorter than visible light and belong to the invisible light range. They damage bacterial cell walls, change cell permeability and the colloidal properties of the cytoplasm, inhibit enzyme activity, and kill bacteria by damaging the DNA and RNA of the cell.

By utilizing the property of ultraviolet rays to kill microorganisms, sewage treatment plants and fish farms have been using ultraviolet sterilizers that can be simply connected to pipes to kill bacteria in water. The commonly used method of using ultraviolet rays uses an ultraviolet lamp in the form of a straight hollow tube made of a transparent material, specifically a quartz tube, and the ultraviolet lamp is protected from contact with the fluid by a quartz tube or the like.

At this time, if the quartz tube is used continuously, it becomes contaminated by microorganism films or foreign substances such as water stains, sediments, and deposits, and the accumulation of such foreign substances reduces the transmission of ultraviolet rays from the ultraviolet lamp into the fluid, which causes a decrease in the intensity of ultraviolet light and becomes a factor in reducing the treatment efficiency of ultraviolet disinfection and sterilization.

In addition, when performing water treatment using the above method, there was a problem that the water treatment efficiency was low and proper water treatment was not performed because physical methods using filters, etc. or chemical methods using ultraviolet rays, etc. were used and complex water treatment was not performed.

As a conventional technology to solve this problem, there is a 'water treatment device using bubbles and oxidation' (Korean Patent No. 10-2284856) that removes foreign substances in contaminated water by adsorbing them to the bubbles by generating bubbles in the contaminated water.

When bubbles are generated within contaminated water, foreign substances within the contaminated water are absorbed by the bubbles and float together, forming a group of scum. This has the advantage that users can quickly and effectively purify contaminated water simply by removing the scum on the water surface.

However, the water treatment device described above has a problem in that the efficiency of purifying contaminated water is somewhat low because the treated water and scum from which contaminants have been removed are not clearly separated and discharged but are mixed at a certain ratio. In addition, the conventional water treatment device has a disadvantage in that since the bubbles do not evenly contact the entire contaminated water, only some of the foreign substances in the contaminated water are absorbed by the bubbles and float up, and the remaining foreign substances are discharged together with the treated water.

KR 10-2284856 B1

The present invention has been proposed to solve the above problems, and the purpose of the present invention is to provide a water treatment device capable of purifying contaminated water more quickly and effectively by removing foreign substances in contaminated water using microbubbles and clearly distinguishing between treated water from which foreign substances have been removed and scum.

In order to achieve the above-described purpose, the water treatment device according to the present invention comprises: an outer strainer formed in a vertically erected cylindrical shape and having a plurality of outer through holes formed in a side wall; an inner strainer formed in a vertically erected cylindrical shape and installed inside the outer strainer and having a plurality of inner through holes formed in a side wall; a main catalytic electrode composed of a plurality of main electrode plates arranged to be stacked vertically but spaced apart from each other, and a main electrode rod coupled so that one longitudinal end penetrates the plurality of main electrode plates, and installed inside the inner strainer; an inlet pipe for supplying contaminated water into the inner strainer; and an outlet pipe for guiding treated water passing through the inner through holes and the outer through holes to the outside.

The inner strainer rotates in one direction, and the outer strainer and the main catalyst electrode rotate in the opposite direction to the inner strainer.

The above main electrode plate is formed in a mesh shape.

The above main electrode plate is formed to be inclined so as to form a spiral, so that the main catalyst electrode is configured to transport the fluid upward when rotating.

It further includes a pre-catalyst electrode installed inside the inlet tube, which is composed of a plurality of pre-electrode plates that are arranged to be stacked in the thickness direction but spaced apart from each other, and a pre-electrode rod that is coupled to penetrate the plurality of pre-electrode plates.

An outlet filter for filtering the treated water is provided on the outlet side of the above-mentioned outlet pipe.

The entire outlet end of the above inlet pipe is in close contact with the entire lower end of the inner strainer, but a step is formed at a portion spaced a certain distance from the outlet end on which the lower end of the outer strainer is seated.

It further includes a return pipe for returning the fluid discharged from the upper part of the inner strainer and the outer strainer to the inlet pipe, and a scum discharge pipe for discharging scum that rises through the inner through hole and the outer through hole to the outside.

It further includes a return pipe for returning the fluid discharged from the inner strainer and the upper part of the outer strainer to the inlet pipe; a scum discharge pipe for discharging scum discharged from the inner strainer and the upper part of the outer strainer to the outside; and a strainer net installed between the inlet side of the return pipe and the upper part of the outer strainer.

The inlet side of the above return pipe and the inlet side of the above scum discharge pipe are horizontally connected to each other, and the above filter net has one side close to the return pipe joined to the upper end of the outer strainer, and the other side close to the above scum discharge pipe joined to the upper inner wall of the above scum discharge pipe.

The above scum discharge pipe is arranged with the ends inclined so that the discharge side is higher than the inlet side.

The inner surface of the outer strainer and the outer surface of the inner strainer are spaced apart, and the outer through hole and the inner through hole are formed to overlap or misalign with each other according to the rotation of the outer strainer and the inner strainer.

The water treatment device according to the present invention has the advantage of being able to remove foreign substances in contaminated water more quickly by supplying a large amount of microbubbles into the contaminated water, and preventing the phenomenon of scum being mixed into the treated water by clearly distinguishing and discharging the treated water from which foreign substances have been removed.

Hereinafter, an embodiment of a water treatment device according to the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a schematic diagram of a water treatment device according to the present invention, and Figure 2 is an exploded perspective view of an outer strainer, an inner strainer, and a main catalyst electrode included in the present invention.

The water treatment device according to the present invention is a device that uses the surface charge of bubbles to adsorb foreign substances contained in the polluted water to the bubbles and coagulate them in the form of scum, and its greatest feature is that it allows purified treated water to be discharged separately from the scum floating on the surface of the water, thereby enabling the treated water to be discharged in a cleaner state.

That is, the water treatment device according to the present invention comprises an outer strainer (200) formed in a vertically erected cylindrical shape and having a plurality of outer through holes (210) formed in the side wall, an inner strainer (300) formed in a vertically erected cylindrical shape and installed inside the outer strainer (200) and having a plurality of inner through holes (310) formed in the side wall, a plurality of main electrode plates (410) arranged to be stacked in the vertical direction but spaced apart from each other, and a main electrode rod (420) coupled so that one end in the longitudinal direction penetrates the plurality of main electrode plates (410), a main catalyst electrode (400) installed inside the inner strainer (300), an inlet pipe (100) for supplying contaminated water into the inner strainer (300), and a main catalytic electrode (400) passing through the inner through holes (310) and the outer through holes (210). Its structural feature is that it consists of an outlet pipe (600) that guides the treated water to the outside.

As illustrated in Fig. 1, the contaminated water supplied through the inlet pipe (100) flows into the inner strainer (300). Since a main catalyst electrode (400) that generates a large amount of microbubbles is installed inside the inner strainer (300), the contaminated water flowing into the inner strainer (300) comes into contact with a large amount of microbubbles.

When contaminated water comes into contact with a large amount of microbubbles in this way, foreign substances in the contaminated water are adsorbed to the microbubbles and float to the surface of the water together with the microbubbles, and through a process of clumping together with other foreign substances, form scum (S). The process of generating microbubbles and the process of adsorbing foreign substances to the microbubbles are described in detail in Korean Patent No. 10-2284856 entitled “Water treatment device using bubbles and oxidation,” and a detailed description thereof is omitted.

At this time, the treated water, which has been treated so that foreign substances are adsorbed to microbubbles, enters the outlet pipe (600) through the inner through hole (310) of the inner strainer (300) and the outer through hole (210) of the outer strainer (200). Since the scum (S) does not flow sideways through the inner through hole (310) and the outer through hole (210) but floats to the surface, only the treated water with foreign substances removed flows through the outlet pipe (600).

As mentioned above, when using the water treatment device according to the present invention, only the treated water with foreign substances removed passes through the inner through hole (310) and the outer through hole (210) and flows out to the outside, so there is an advantage in that the phenomenon of scum (S) being mixed in the treated water flowing out through the discharge pipe (600) can be prevented.

At this time, even if foreign substances in the contaminated water are removed to the maximum extent possible using microbubbles, foreign substances may also be contained in the treated water flowing along the outlet pipe (600), so an outlet filter (610) for filtering the treated water may be provided at the outlet side of the outlet pipe (600). The outlet filter (610) may be applied as various types of filters such as a physical filter, an electrical filter, or a chemical filter, as long as it can remove foreign substances.

Meanwhile, in order for foreign substances in the contaminated water to be more effectively adsorbed to the microbubbles, the microbubbles and the contaminated water must be evenly mixed. In order to evenly mix the microbubbles and the contaminated water and to cause the contaminated water to flow while generating a vortex, the main catalyst electrode (400) may be configured to rotate.

And, the inner strainer (300) may be configured to rotate in the opposite direction to the main catalyst electrode (400), and the outer strainer (200) may be configured to rotate in the opposite direction to the inner strainer (300) and in the same direction as the main catalyst electrode (400).

That is, when the inner strainer (300) and the outer strainer (200) rotate in opposite directions and the inner strainer (300) and the main catalyst electrode (400) rotate in opposite directions, a vortex is generated inside the inner strainer (300) and the outer strainer (200), so that the microbubbles and contaminated water can be mixed very evenly.

In addition, in order to increase the efficiency of removing foreign substances in the contaminated water, the amount of microbubbles generated by the main catalyst electrode (400) must be increased. In order to increase the amount of microbubbles generated, the contact area between the main electrode plate (410) and the contaminated water must be secured as wide as possible.

In order to increase the contact area between the main electrode plate (410) and the contaminated water in the water treatment device according to the present invention, the main electrode plate (410) may be formed in a mesh shape. At this time, if the mesh aperture size is large, the contact area between the main electrode plate (410) and the contaminated water may decrease, so it is preferable that the mesh aperture size of the main electrode plate (410) be limited within an appropriate range. In addition, as is well known to those skilled in the art, the main electrode plate (410) may have a structure in which the positive electrode plate (412) and the negative electrode plate (414) are alternately arranged. To this end, the main electrode rod (420) may be provided with a positive terminal (not shown) connected to the positive electrode plate (412) and a negative terminal (not shown) electrically connected to the negative electrode plate (414).

Meanwhile, in order to allow the contaminated water provided through the inlet pipe (100) to preemptively undergo a process of coming into contact with microbubbles before flowing into the inner strainer (300), a pre-catalyst electrode (110) may be provided inside the inlet pipe (100). At this time, the pre-catalyst electrode (110) may be manufactured substantially identically to the main catalyst electrode (400). That is, the pre-catalyst electrode (110) may be composed of a plurality of pre-electrode plates (112) that are arranged to be stacked in the thickness direction but spaced apart from each other, and a pre-electrode rod (114) that is coupled to penetrate the plurality of pre-electrode plates (112). The pre-electrode plates (112) may also have a structure in which positive and negative plates are alternately arranged, similarly to the main catalyst electrode (400). The above pre-catalyst electrode (110) may also be configured to rotate so that the microbubbles and contaminated water are evenly mixed and the contaminated water flows while generating a vortex.

In this way, when the pre-catalyst electrode (110) is installed inside the inlet pipe (100), not only does the contaminated water come into contact with more microbubbles, but the time it comes into contact with the microbubbles is significantly increased, so there is an advantage in that the effect of foreign substances in the contaminated water being adsorbed to the microbubbles can be maximized.

The water treatment device included in the present invention is configured so that the entire outlet end of the inlet pipe (100) is in close contact with the entire lower end of the inner strainer (300) so that all of the contaminated water supplied through the inlet pipe (100) is supplied into the inner strainer (300). At this time, if the space between the lower end of the inner strainer (300) and the lower end of the outer strainer (200) is open downward, the treated water passing through the inner through hole (310) of the inner strainer (300) may not pass through the outer through hole (210) of the outer strainer (200) and may be discharged downward as is.

Therefore, it is preferable that the space between the bottom of the inner strainer (300) and the bottom of the outer strainer (200) be configured so that the bottom is blocked. For example, it is preferable that a step (102) is formed at a portion of the inlet pipe (100) that is a certain distance away from the outlet end, so that the treated water passing through the inner through hole (310) of the inner strainer (300) passes through the outer through hole (210) of the outer strainer (200) and flows down to the outlet pipe (600).

Meanwhile, since the treated water discharged upward from the top of the inner strainer (300) and the outer strainer (200) contains scum (S), it is returned to the inlet pipe (100) so that the process of contacting microbubbles can be repeated. That is, the water treatment device according to the present invention has a return pipe (500) that returns the fluid discharged from the top of the inner strainer (300) and the outer strainer (200) to the inlet pipe (100).

In addition, a small amount of scum (S) may be mixed in the treated water discharged to the outlet pipe (600) through the outer through hole (210) of the outer strainer (200). At this time, the scum (S) mixed in the treated water has a characteristic of floating to the surface of the water, so it is preferable that the water treatment device according to the present invention be configured to discharge the scum (S) floating on the surface of the treated water introduced into the outlet pipe (600) to the outside.

That is, as shown in Fig. 1, the water treatment device according to the present invention may additionally be provided with a scum discharge pipe (700) that discharges scum (S) that has risen through the inner through hole (310) and the outer through hole (210) to the outside.

In this way, when a scum discharge pipe (700) is provided, even if the treated water flowing into the discharge pipe (600) contains a certain level of scum (S), the scum (S) that has risen to the surface of the discharge pipe (600) is not discharged together with the treated water but is captured in a separate scum (S) collection tank (not shown), so there is an advantage in that scum (S) treatment becomes easier.

Figure 3 is a cross-sectional view showing the operation of the outer strainer (200) and the inner strainer (300) included in the present invention.

In the process where the contaminated water supplied into the inner strainer (300) comes into contact with the microbubbles generated from the main catalyst electrode (400), a large amount of scum (S) is generated. At this time, most of the scum (S) floats to the surface of the water, but scum (S) with a small particle size passes through the outer penetration hole (210) and the inner penetration hole (310) together with the treated water.

If a phenomenon occurs in which scum (S) passes through the outer penetration hole (210) and the inner penetration hole (310) in this way, the outer penetration hole (210) and the inner penetration hole (310) may be blocked by scum (S), resulting in a problem in which the treated water cannot be smoothly discharged to the discharge pipe (600).

In particular, when the treated water passes through the inner through hole (310), the flow rate is above a certain level, so the inner through hole (310) is not easily clogged with scum (S), but when the treated water passes through the outer through hole (210), the flow rate is somewhat reduced, so the outer through hole (210) may frequently become clogged with scum (S).

The water treatment device according to the present invention can prevent the inner through hole (310) and the outer through hole (210) from being blocked by scum (S) by using the pressure difference by causing the outer strainer (200) and the inner strainer (300) to rotate (rotate) in opposite directions.

At this time, since the main catalyst electrode (400) also rotates, in order to smoothly discharge the treated water, when the main catalyst electrode (400) rotates clockwise, the inner strainer (300) may be configured to rotate counterclockwise and the outer strainer (200) may be configured to rotate clockwise. Alternatively, when the main catalyst electrode (400) rotates counterclockwise, the inner strainer (300) may be configured to rotate counterclockwise and the outer strainer (200) may be configured to rotate counterclockwise.

That is, the inner strainer (300) may be configured to rotate in one direction, and the outer strainer (200) and the main catalyst electrode (400) may be configured to rotate in the opposite direction to the inner strainer (300).

In this state, the treated water inside rotates in the same direction as the main catalyst electrode (400) and then collides with the inner wall and inner through hole (310) of the inner strainer (300) that rotates in the opposite direction, so that the treated water easily flows out to the outside through the inner through hole (310), and due to the force or pressure of the treated water colliding with it, it becomes difficult for scum (S) or foreign substances to adhere around the inner through hole (310), and clogging of the inner through hole (310) can be prevented or minimized.

This can also be applied to the outer penetration hole (210). Since the treated water passing through the inner penetration hole (310) rotates in the rotational direction of the inner strainer (300), the treated water easily flows out to the outside through the outer penetration hole (210) when it collides with the inner wall of the outer strainer (200) and the outer penetration hole (210) that rotate (or rotate) in the opposite direction, and the force or pressure of the treated water colliding with it makes it difficult for scum (S) or foreign substances to adhere around the outer penetration hole (210), and clogging of the outer penetration hole (210) can be prevented or minimized.

Additionally, the treated water flowing out through the inner through hole (310) can prevent the outer through hole (210) from being clogged by passing through the outer through hole (210) using a method that utilizes a pressure difference.

For example, as illustrated in FIG. 3, the inner surface of the outer strainer (200) and the outer surface of the inner strainer (300) may be configured to be spaced apart from each other, but the outer through hole (210) and the inner through hole (310) may be arranged so as not to overlap each other but to be misaligned (see FIG. 3(a)) or overlap each other (see FIG. 3(b)) depending on the rotation angle of the outer strainer (200) and the inner strainer (300). That is, depending on the rotation of the outer strainer (200) and the inner strainer (300), the outer through hole (210) and the inner through hole (310) may overlap each other (superimposed) at a specific time period, and the outer through hole (210) and the inner through hole (310) may be arranged so as not to overlap each other at a specific other time period.

As shown in Fig. 3(a), when the outer through hole (210) and the inner through hole (310) do not overlap but are misaligned, the treated water passing through the inner through hole (310) does not pass through the outer through hole (210) immediately but hits the inner wall of the outer strainer (200) and returns, so the treated water existing between the outer strainer (200) and the inner strainer (300) becomes compressed. In this case, the pressure between the outer strainer (200) and the inner strainer (300) increases.

In this state, as shown in Fig. 3(b), when the outer strainer (200) and the inner strainer (300) rotate so that the outer through hole (210) and the inner through hole (310) overlap, the treatment water compressed between the outer strainer (200) and the inner strainer (300) passes through the outer through hole (210) at a high speed, thereby preventing the outer through hole (210) from being blocked by scum (S).

Accordingly, the effect of preventing the outer through hole (210) from being blocked by scum (S) due to the pressure difference between the outer strainer (200) and the inner strainer (300) can be obtained.

Figure 4 is a side view of the main catalyst electrode (400) included in the second embodiment of the water treatment device according to the present invention.

The water treatment device according to the present invention is configured so that the main catalyst electrode (400) rotates so that the contaminated water and microbubbles can be mixed more evenly, and the rotating force of the main catalyst electrode (400) can be configured so that it is utilized as a force for the treatment water to flow upward.

For example, as shown in Fig. 4, the main electrode plate (410) may be formed to be inclined to form a spiral shape so that the treated water is well mixed while being transported upward when the main catalyst electrode (400) rotates. When the main electrode plate (410) is formed in a spiral shape in this way, the treated water can flow smoothly upward without a separate pump, so there is an advantage in that the treated water can be discharged more smoothly.

In addition, as mentioned above, when the main electrode plate (410) is formed in a spiral shape, the main electrode plate (410) generates a vortex during the process of the main catalyst electrode (400) rotating, so that the contaminated water and microbubbles can come into contact more quickly and effectively.

In addition, the pre-electrode plate (110) is also configured in a spiral shape like the main electrode plate (410) to generate a vortex to facilitate forward transport and ensure good mixing.

Figure 5 is a schematic diagram of a third embodiment of a water treatment device according to the present invention.

As in the embodiment illustrated in Fig. 1, if all of the fluid (a mixture of treated water and scum (S)) discharged from the top of the inner strainer (300) and the outer strainer (200) is returned to the inlet pipe (100), the scum (S) returned to the inlet pipe (100) is again introduced into the inner strainer (300), which may cause a problem in that the water treatment effect is reduced.

Therefore, the water treatment device according to the present invention can be configured so that scum (S) among the fluid discharged from the upper part of the inner strainer (300) and the outer strainer (200) is not returned to the inlet pipe (100), and only the treated water is returned to the inlet pipe (100).

For example, the water treatment device according to the present invention is provided with a return pipe (500) that returns the fluid discharged from the upper end of the inner strainer (300) and the outer strainer (200) to the inlet pipe (100), and a scum discharge pipe (700) that discharges scum (S) discharged from the upper end of the inner strainer (300) and the outer strainer (200) to the outside, and a strainer net may be installed between the inlet side of the return pipe (500) and the upper end of the outer strainer (200).

In this way, when a strainer is installed between the inlet side (right side in FIG. 5) of the return pipe (500) and the upper part of the outer strainer (200), scum (S) among the fluid discharged through the inner strainer (300) and the upper part of the outer strainer (200) is filtered by the strainer, and only the treated water can be returned to the inlet pipe (100) through the return pipe (500).

At this time, so that the scum (S) filtered through the strainer can smoothly flow into the scum discharge pipe (700), the inflow side of the return pipe (500) and the inflow side of the scum discharge pipe (700) are horizontally connected to each other, and the strainer can be arranged to be inclined in a direction away from the upper ends of the inner strainer (300) and the outer strainer (200) as it gets closer to the scum discharge pipe (700).

That is, as shown in FIG. 5, the filter net may be connected to the upper end of the outer strainer (200) at one end (left side in FIG. 5) close to the return pipe (500), and may be connected to the upper inner wall of the scum discharge pipe (700) at the other end (right side in FIG. 5) close to the scum discharge pipe (700).

When the above-mentioned filter net is arranged in an inclined manner in this manner, scum (S) that cannot pass through the filter net and settles on the bottom surface of the filter net can smoothly flow into the scum discharge pipe (700) along the inclined surface of the filter net.

Furthermore, in order for the scum (S) introduced into the scum discharge pipe (700) to smoothly move toward the scum (S) collection tank (not shown) through the scum discharge pipe (700), it is preferable that the scum discharge pipe (700) be arranged with the middle section inclined so that the discharge side is higher than the inlet side.

At this time, the angle of inclination of the filter net or the angle of inclination of the scum discharge pipe (700) should be appropriately selected according to various conditions such as the type or amount of scum (S) generated and the flow rate of contaminated water and treated water.

Above, although the present invention has been described in detail using preferred embodiments, the scope of the present invention is not limited to specific embodiments, and should be interpreted by the appended claims. In addition, those who have acquired common knowledge in this technical field should understand that many modifications and variations are possible without departing from the scope of the present invention.
