DETAILED DESCRIPTION

[0018] See also Figure 1-2 , the embodiments of the utility model are further described;

[0019] An environmentally friendly pure water wall comprises a body 1, a plurality of RO membrane shells 3 are evenly installed on the upper part of the body 1, a booster pump is installed in the leftmost RO membrane shell 3, and RO membranes are installed in the other RO membrane shells 3, a pure water outlet pipe 4 and a water inlet pipe 15 are plugged into the body 1, and the pure water outlet pipe 4 is connected to the water outlet ends of the other RO membrane shells 3 through a plurality of connecting pipes;

[0020] A pure water return pipe 8 is provided in the body 1, and the pure water return pipe 8 is connected with the water outlet end of the leftmost RO membrane shell 3 and the water inlet ends of the other RO membrane shells 3, and a return water electric valve 7 is installed on the pure water return pipe 8, and a domestic water pipe network 16 is connected between the pure water outlet pipe 4 and the pure water return pipe 8;

[0021] A liquid storage tank 9 is placed at the lower part of the body 1, a sewage pipe 13 is connected between the top of the liquid storage tank 9 and the sewage discharge end of the remaining RO membrane shells 3, a pipe 19 is installed between the sewage pipe 13 and the liquid storage tank 9, a sewage electric valve 20 is installed on the pipe 19, a sewage electric valve 15, a manual regulating valve 17 and a flow meter 18 are installed on the sewage pipe 13, the pipe 19 is located between the manual regulating valve 17 and the flow meter 18, the sewage electric valve 15 is located at the end of the sewage pipe 13, and a pumping assembly is provided in the liquid storage tank 9;

[0022] A control module is installed on the machine body 1. For example, the control module may be a control panel, a PLC controller or other controllers. The pressure value of the booster pump may be preset through the control module.

[0023] The water inlet pipe 15 is connected to the tap water pipe. The RO membrane in the RO membrane shell 3 can remove particles dissolved in water to obtain pure water. After the RO membrane has been used for a period of time, the particles attached to the outside of the RO membrane need to be flushed to improve the cleanliness of the pure water and increase the life of the RO membrane.

[0024] The flushing of RO membrane is usually completed in two procedures: real-time flushing and timed flushing:

[0025] Under the pressure provided by the booster pump, the pure water obtained after the tap water passes through the RO membrane reverse osmosis will reach the hollow channel of the RO membrane, and then output the pure water through the water outlet end of the RO membrane shell 3, and then supply it to the water use end through the pure water outlet pipe 4, wherein the water-soluble particles will be blocked by the RO membrane and will remain on the outer surface of the RO membrane. Real-time flushing is to open the sewage electric valve 5 during the real-time water production period of the booster pump. Under the action of water pressure, the water-soluble particles (called sewage) remaining on the outer surface of the RO membrane will flow into the sewage pipe 13, and then pass through the sewage electric valve 5 to be discharged into the liquid storage tank 9 to store the sewage. The manual regulating valve 17 and the flow meter 18 are designed to adjust the sewage discharge ratio so that the drainage volume and the amount of pure water reach an economical balance point; it should be noted that the opening and closing degree of the manual regulating valve 17 is adjusted in advance and will not change;

[0026] In addition to real-time flushing, timed flushing is also used to increase the service life of the RO membrane and the quality of pure water. Real-time flushing is a low-flow flushing, while timed flushing is a high-flow flushing. Timed flushing is usually scheduled during the time period when users do not use water every day. For example, at 2 a.m., when the timed flushing starts, the system will turn off the booster pump, open the sewage electric valve 20 and the return water electric valve 7. Under the action of water pressure, the pure water in the pipeline flows through the return water electric valve 7 and the outer surface of the RO membrane through the sewage pipe 13, the pipe 19 and the sewage electric valve 20 to the liquid storage tank 9. After a period of time, the indoor water in the user end is The residual pressure in the domestic water network 16 will decrease and approach zero. A pressure sensor is provided on the pure water outlet pipe 4 to detect the water pressure in real time. The pressure sensor feeds back the measured data to the control module. After the control module senses the low pressure data, it will close the sewage electric valve 20 and the return water electric valve 7 and start the booster pump. Under the use of the booster pump, pure water will be produced and the pipeline pressure will be increased to the set value. After the pressure in the user-side pure water pipeline system reaches the specified value, the pure water pipeline system will open the sewage electric valve 20 and the return water electric valve 7 again to enter the pure water flushing state. The reciprocating program will last for 3 minutes and then stop the timed flushing program. It is worth mentioning that the 3-minute flushing time mentioned in the article and the pressure setting value of the booster pump during flushing are both adjustable and can be adjusted according to the flushing effect in order to achieve the best state.

[0027] During the timed flushing process, the water pressure in the pure water pipeline system at the user end fluctuates between high and low pressures, that is, the water therein also flows in a wave-like manner, with a pulse nature, and has a very good cleaning effect.

[0028] During the timed flushing process, the problem of the storage of pure water in the user's indoor domestic water pipe network 16 can also be solved. That is, if the user is not at home, or there are many toilets in the user's home, it is very likely that some of the pipes or the pure water stored in the domestic water pipe network 16 will not be used for a certain period of time, which is called "aging water" or "dead water". The domestic water pipe network 16 in the utility model is as shown in the attached Figure 2 As shown, the water points and water points, that is, the cold water angle valves and cold water angle valves are connected and arranged in a "hand-in-hand" manner, rather than the traditional common connection and arrangement of the three-way to the angle valve. The "hand-in-hand" connection and arrangement method minimizes the "dead corners" of the pipeline when flushing the domestic water pipe network 16. Since the pure water outlet pipe 4 is connected to the domestic water pipe network 16, and the pure water return pipe 8 is connected to the domestic water pipe network 16, the body 1 and the domestic water pipe network 16 form a connected closed loop, and the pure water wall flushing solution can effectively solve the "dead water" problem of the domestic water pipe network 16.

[0029] The sewage after flushing will flow into the liquid storage tank 9 through the sewage pipe 13. The liquid storage tank 9 is used to collect sewage. The sewage can be reused for a second time, such as flushing the yard, watering the plants, and mopping the floor, thus saving water resources.

[0030] If the user wants to use the treated sewage, an external water pipe is connected to the end of the pumping assembly, and the pumping assembly is started to pump the sewage in the liquid storage tank 9 into the external water pipe, so that the water can be used to wash the yard, water the plants, mop the floor, etc.

[0031] The pumping assembly includes a liquid pump 10, a water outlet pipe 11 and a manual valve 12. The liquid pump 10 is installed at the lower part of the liquid storage tank 9. The water outlet pipe 11 is fixed at the water outlet end of the liquid pump 10, and the end of the water outlet pipe 11 passes through the machine body 1. The manual valve 12 is installed on the water outlet pipe 11.

[0032] If the user wants to use the treated sewage, an external water pipe is connected to the end of the outlet pipe 11, and then the manual valve 12 is opened, and then the liquid pump 10 is connected to an external power supply. The liquid pump 10 will pump the treated sewage in the liquid storage tank 9 into the outlet pipe 11, and the outlet pipe 11 will then guide the water to the external water pipe, so that the water can be used to wash the yard, water the plants, mop the floor, etc.

[0033] A breathing valve 14 is installed on the top of the liquid storage tank 9;

[0034] The breathing valve 14 can solve the exhaust problem in the process of sewage flowing into the liquid storage tank 9 and the air intake problem of the water in the liquid storage tank 9 for secondary use.

[0035] An overflow drain pipe 6 is plugged into the top of the liquid storage tank 9, and the outer end of the overflow drain pipe 6 passes through the machine body 1;

[0036] If the liquid storage tank 9 is filled with sewage and is not in use, the excess sewage will be discharged into the sewer outside the machine body 1 through the overflow sewage pipe 6.

[0037] A door panel 2 is installed on one side of the body 1;

[0038] The door panel 2 is provided to facilitate the user to inspect the components inside the machine body 1 .
