Description
Technical Field
The invention belongs to the technical field of reverse osmosis water purifiers, relates to the technical problems of whether a reverse osmosis water purifier has waste water or not, the flow rate and whether the reverse osmosis water purifier can continuously discharge pure water or not, and particularly relates to the technical problems of how to solve the problem of no waste water by using a water storage tank and how to realize large-flow continuous pure water discharge by driving of tap water.
Background
With the continuous improvement of living standard of people, more and more people begin to pay attention to drinking water sanitation, various water purifiers appear on the market, the current reverse osmosis water purifier is abnormally and rapidly developed in China, the proportion of the reverse osmosis water purifier in the whole water purifier is larger and larger, the proportion of the reverse osmosis water purifier in 2019 is more than 90%, and the reverse osmosis water purifier has a tendency of continuously increasing. Before 2020, the reverse osmosis water purifier has small flow, and most of the reverse osmosis water purifiers are matched with water storage tanks.
The RO reverse osmosis water purification device water storage tank before 2020 is an air bag type water storage tank, pure water enters the 14 compression air bags of the pure water area in the water making process, the water discharging process is carried out, the air volume expands to release potential energy to discharge the pure water in the pure water area 14, and a plurality of problems exist in the use process of the RO reverse osmosis water purification device water storage tank:
more than 75% of water in the water making process of the air bag type reverse osmosis water purifier is not used, and when waste water is discharged into a waste water ditch, waste of water is caused. The air of the air bag type water storage tank occupies more than 50% of the volume of the tank, and the volume utilization rate of the tank is low.
The air pressure of the air bag type water storage tank is gradually reduced in the pure water discharging process, and the flow of the pure water is reduced along with the reduction of the pressure. Compared with the reverse osmosis water purifier without the air bag type water storage tank, the flow rate is better or uneven, and the flow rate is reduced more quickly.
The air bag type water storage tank is provided with an air valve, air with certain pressure must be pumped into the air bag type water storage tank before leaving a factory, if the air is not pumped into the water storage tank, the air exists in the water storage chamber, and the air bag type water storage tank cannot be used. The pumping pressure does not meet the requirement, and the flow and the water yield are also influenced.
The air bag type water storage tank begins to discharge water, 30% of water is discharged, in order to keep higher flow, the high-pressure pump 4 of the water purifier is started, more than 70% of water is always stored in the tank, the inlet and the outlet of the water storage tank are positioned at the highest point of the barrel, more dead water exists, and bacteria are easy to breed.
The air bag type pressure tank is large in size, poor in pressure resistance and high in air pressure energy storage amount, once a high-voltage switch breaks down, the blasting destructiveness is very large, and the air bag type water storage tank is often reported as an explosion event. The air bag type water storage tank has frequent start, more faults, high damage rate and short service life of only two years.
The air bag type water storage tank high-pressure pump 4 not only needs to overcome the resistance of the reverse osmosis membrane 5 to do work, but also needs to overcome the air pressure of the water storage tank to do work, and the air potential energy in the water storage tank is stored in the process. As the pressure in the water storage tank is gradually increased, the actual power of the high-pressure pump 4 is also gradually increased, and the rated power of the high-pressure pump 4 is required to be larger than the maximum actual power, so that the rated power of the high-pressure pump 4 is far larger than the average power.
The market trend develops to a large-flow reverse osmosis membrane 5, a double reverse osmosis membrane 5 and a water-free tank in the year 2020. The use of the large-flow reverse osmosis membrane 5 reduces the volume, can continuously discharge pure water, and the air bag type pressure tank is gradually eliminated. But reverse osmosis membrane 5 flow that is bigger again also can't compare with running water flow, the power failure just can't put the pure water to reverse osmosis membrane 5 flow has been big and has brought the new problem, product cost has improved, the pure water is put simultaneously in system water, the TDS value of the initial system water of reverse osmosis membrane 5 within two minutes is very high, the pure water quality has reduced, the pure water is put simultaneously in system water, the start frequency is too high and has higher requirement to the booster pump quality, the rational use problem that concentrated water can not be solved to no retaining jar again, the waste of water still exists.
