Description

Multi-stage high-efficiency oil mist purification device

technical field

The utility model relates to a high-efficiency oil mist purification device, which is used for the removal of tiny oil droplets, and is especially suitable for the treatment of oil mist waste gas containing cutting fluid, oil, etc. generated during the tool cutting process of a processing machine tool, and particularly relates to a multi-stage high-efficiency oil mist purification device. Fog purification device.

Background technique

When metal blanks are subjected to high-temperature conditions during machining such as turning, milling, and drilling, the oil-based lubricating coolant begins to atomize and gasify, and at the same time, the additives in the oil and the metal powder produced by processing begin to coke and float, forming a large number of harmful high-temperature three The phase oil mist gas is dispersed in the workshop atmosphere. These oil mist exhaust gases contain toxic and harmful substances such as acrolein and polychlorinated biphenyls, which endanger the health of operators and pollute the environment. The simple filtration in the current exhaust gas treatment device is difficult to meet the emission standards; while the investment in complex systems is too high, and the operation and maintenance costs are unaffordable.

Utility model content

The purpose of the utility model is to overcome the investment and operation cost and the dilemma of up-to-standard discharge existing in the current oil mist waste gas treatment, and provide an oil mist waste gas treatment device with compact structure, high treatment efficiency and low investment and operation cost.

In order to achieve the above purpose, the utility model provides the following technical solutions: the exhaust gas enters the device, and passes through the impact filter, the metal mesh filter, the primary effect filter and the medium effect filter from bottom to top, which can be a bag filter , Guarantee the filter to complete the purification and discharge.

The impingement filter is groove-shaped, and the notch is downward, and multi-layer resistance plates arranged in a staggered manner are arranged in the groove, and the material of the resistance plates is metal or engineering plastics.

The impact filter is made of metal or engineering plastics.

The resistance plate is round or square.

The thickness of the metal mesh filter is 10-100mm.

The primary filter is made of non-woven fabric.

The medium-efficiency filter is made of non-woven fabric.

The guarantee filter is made of non-woven fabric.

The multi-stage high-efficiency oil mist purification device of the utility model, wherein the impact filter utilizes the principle of inertial impact, and after the large drop hits the baffle plate of the filter, it will be separated from the gas to achieve preliminary filtration; The principle is to realize the function of demisting and to separate the liquid droplets above 10 μm in the exhaust gas; the filtration accuracy of the primary filter is slightly higher, and it has a better separation effect on the dust and liquid droplets of 10 μm; the bag filter is good for the dust of 5 μm It has a high separation efficiency with liquid droplets; the guarantee filter is a further guarantee for the separation effect, ensuring that the liquid droplets in the exhaust gas can be effectively separated, so that the exhaust gas can meet the national environmental protection requirements.

Detailed ways:

Example

As shown in Figure 1, the multi-stage high-efficiency oil mist purification device is arranged from bottom to top with impact filter, metal mesh filter, primary filter, medium filter and guarantee filter.

The percussion filter 1 is groove-shaped, and the notch is downward, and multi-layer staggered resistance plates are arranged in the groove, and the material of the resistance plates is metal or engineering plastics. The impact filter is made of metal or engineering plastics. The resistance plate is round or square.

The metal mesh filter 2 has a thickness of 10-100mm.

The primary filter 3 is made of non-woven fabric.

The medium-efficiency filter 4 can be a bag filter made of non-woven fabric.

The guarantee filter 5 is made of non-woven fabric.

The multi-stage high-efficiency oil mist purification device, wherein the impact filter uses the principle of inertial impact, and after the large droplets hit the baffle of the filter, it will be separated from the gas to achieve preliminary filtration; the metal mesh filter uses the principle of filtration retention , to achieve the effect of demisting, and to separate the droplets above 10μm in the exhaust gas; the filtration accuracy of the primary filter is slightly higher, and it has a better separation effect on the dust and droplets of 10μm; the bag filter is good for the dust and droplets of 5μm The liquid droplets have a high separation efficiency; the guarantee filter is a further guarantee for the separation effect, ensuring that the liquid droplets in the exhaust gas can be effectively separated, so that the exhaust gas meets the national environmental protection requirements.
