Problems solved by technology

[0004] The previous reverse osmosis membrane water purifiers were concentrated water discharge type, that is, the concentrated water after primary purification and filtration was discharged directly as waste water, which is indeed a great waste, especially for small household and commercial water purifiers. , the raw water is tap water, the water quality of the concentrated water produced after one purification and filtration is not worse than that of the raw water, and it has the value of utilization, and can be further purified twice or three times. If the concentrated water is directly discharged as waste water, it will not only Increase the cost of water purification, and it is also a waste of water resources

Embodiment 1

[0053] Such as figure 1 As shown, a kind of wastewater-free water purifier of the present embodiment includes a pre-filter 20, a water inlet solenoid valve 30, a booster pump 40, a filter element mechanism and an RO membrane 60 connected sequentially through pipelines, and the water purifier It also includes a circulating pump 140, a water flow switch 170, a one-way valve 100, a normally open solenoid valve 90, a normally closed solenoid valve 110, a high pressure switch 210, a water storage bucket 130 and a post filter 120,

[0054] The pre-filter 20 is connected to the raw water pipeline 10, the water purification outlet of the RO membrane 60 is connected to a water purification outlet pipe 71, and the outlet end of the water purification outlet pipe 71 is respectively connected to a pure water pipe 712 and a water purification return pipe 711, the clean water return pipe 711 is sequentially provided with the normally open solenoid valve 90 and the one-way valve 100 along t...

Embodiment 2

[0075] Such as figure 2 As shown, the filter element mechanism of the present embodiment includes a secondary composite filter element 54 and a tertiary composite filter element 55 connected in parallel, and the water outlet ends of the secondary composite filter element 54 and the tertiary composite filter element 55 are connected to the RO membrane 60 respectively. The water inlet end is connected, and the pre-filter 20 is an origami filter element with a pore size of 20 μm.

[0076] The first-stage filter element 51 of the present embodiment is an origami filter element with an aperture of 20 μm, and the second-stage composite filter element 54 and the third-stage composite filter element 55 are composite filter elements of activated carbon and PP cotton, and the outer layer of the composite filter element is a composite filter element with an aperture of 1- 5μm PP cotton, PP cotton is filled with sintered activated carbon.

Abstract

The invention relates to the technical field of water purifiers and particularly relates to a water purifier without wastewater. The water purifier without wastewater comprises a pre-filter, a water inlet solenoid valve, a booster pump, a filter core mechanism and an RO film which are in turn connected through a pipe, wherein the pre-filter is connected with a raw water pipeline, a thick water outlet of the RO film is connected with a thick water outlet tube, a circulating pump is arranged on the thick water outlet tube, the outlet end of the thick water outlet tube is respectively connected with a thick water return tube and a domestic water pipeline, the outlet end of the thick water return tube is connected with the outlet end of the booster pump, and a check valve is arranged on the thick water return tube; a normally closed solenoid valve is arranged on the strong discharge protective pipeline; a bypass pipeline is arranged between the raw water pipeline and the domestic water pipeline; a water switch and a check valve are arranged on the bypass pipeline; and the water switch, a normally opened solenoid valve, the normally closed solenoid valve, the booster pump and the circulating pump are respectively electrically connected with an electric control device. By using the water purifier, the thick water cannot be discharged in the pure water production process so that the zero wastewater discharge function can be reached; and the thick water can be reasonably used when the domestic water is used.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a waste water-free water purifier. Background technique [0002] RO reverse osmosis membrane direct drinking machine is also called RO reverse osmosis membrane water purifier. The full name of RO in English is: Reverse Osmosis, that is, reverse osmosis. The reverse osmosis membrane filter cartridge is equipped with a reverse osmosis membrane filter element. Under a certain pressure, water molecules can pass through the RO membrane, while impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, and viruses in the water cannot pass through the RO membrane. membrane, so that part of the water is separated through the RO membrane, and the unpermeable water forms concentrated water due to the increase of solute. Reverse osmosis membrane water purifiers were used in industrial fields such as seawater and brackish water desalination, boiler feed...
