The present invention further provides a dual reverse osmosis system 1000, wherein the dual reverse osmosis system 1000 comprises a dual reverse osmosis device 400, a raw water tank 100 and a pure water storage tank 200, and the specific structure of the dual reverse osmosis device 400 refers to the above-mentioned embodiment. Since the dual reverse osmosis system 1000 adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here. One side of the raw water tank 100 is communicated with a water source, and the other side is communicated with the water inlet cavity 15; the pure water storage tank 200 is communicated with the third water outlet 32, and is used for storing the pure water filtered by the dual reverse osmosis device 400.
Referring to fig. 1, the first water outlet 13 is communicated with the raw water tank 100, and the second water outlet 23 is communicated with the raw water tank 100. Because the water in the first accommodating cavity 11 is in a continuous flowing state, the filtered concentrated water flowing out of the first water outlet 13 is not completely filtered, and can be returned to the raw water tank 100 for circular filtration, so as to improve the conversion rate of pure water and avoid waste. In order to avoid the overhigh concentration of inorganic ions in the raw water tank 100 during the circulating filtration, the water filtered by the first reverse osmosis membrane 21 can flow to the raw water tank 100 through the second water outlet 23 to dilute the concentration of the inorganic ions when the pressure in the second accommodating cavity 24 is overhigh, so that the risk of scaling in the raw water tank 100 is reduced, and the service life of the dual reverse osmosis system 1000 is prolonged.
Referring to fig. 1, the dual reverse osmosis system 1000 further includes an electrode 300, one end of the electrode 300 is located in the raw water tank 100, and the other end of the electrode 300 is located in the water inlet chamber 15. Through the arrangement of the electrode 300, inorganic ions are adsorbed in the raw water tank 100 and the water inlet cavity 15, the inflow of the inorganic ions in the first accommodating cavity 11 is reduced, the scaling probability of the first reverse osmosis membrane 21 is reduced, and the service life of the first reverse osmosis membrane is prolonged.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structural changes made by using the contents of the present specification and the drawings, or any other related technical fields, which are directly or indirectly applied to the present invention, are included in the scope of the present invention.
