Embodiment 1

[0032] This embodiment provides a reverse osmosis membrane filter element flushing system, such as figure 1 As shown, it includes: a reverse osmosis membrane filter element 1, which includes: a water inlet 19 connected to the water inlet pipe 2; a clean water outlet 4 for clean water to flow out; and a concentrated water outlet 5 for concentrated water to flow out; flushing water can pass through the The concentrated water inlet 5 flows into the inside of the reverse osmosis membrane filter element 1 , and is discharged through the water inlet 19 after the reverse osmosis membrane filter element 1 is washed.

[0033] The flushing method of the reverse osmosis membrane in the prior art will cause the scale of the reverse osmosis membrane to start from the water production end, such as carbonate and other inorganic salt scales, etc., and gradually expand to the water inlet end, and finally the entire membrane surface is covered. Full of dirt, the life of the reverse osmosis memb...

Embodiment 2

[0042] This embodiment provides a reverse osmosis system, comprising: the flushing system described in Embodiment 1; a water purification pipe, one end of which is connected to the water purification port, and the other end is connected to the water storage tank; a primary purification module is connected to the The end of the water inlet pipe away from the water inlet is used for primary purification of flushing water.

[0043] Specifically, the primary purification module is a primary purification module, such as activated carbon.

Embodiment 3

[0045] This embodiment provides a water purifier, including the reverse osmosis system described in Embodiment 2.

Abstract

The invention provides a reverse osmosis membrane filter element flushing system, a reverse osmosis system and a water purifier, wherein the reverse osmosis membrane filter element flushing system comprises a reverse osmosis membrane filter element, the reverse osmosis membrane filter element comprises a water inlet connected with a water feeding pipe, a water purification opening through which pure water flows out, and a concentrated water opening through which concentrated water flows out, flushing water can flow into the reverse osmosis membrane filter element through the concentrated wateropening, and after flushing the concentrated water opening, the flushing water is drained through the water inlet. The reverse osmosis membrane filter element flushing system has a forward flushing function for a reverse osmosis membrane and also has a reverse flushing function; by reverse flushing for the reverse osmosis membrane, the high-pressure flushing water can act on an inorganic salt position such as carbonate to enable the carbonate to be released and discharge the carbonate, so that retention of inorganic salt deposits is reduced, the service life of the reverse osmosis membrane isprolonged, and the reverse osmosis membrane purification capacity is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a reverse osmosis membrane filter core flushing system, a reverse osmosis system and a water purifier. Background technique [0002] In natural osmosis, water flows from low concentration to high concentration. Reverse osmosis pressurizes the high-concentration water source to make pure water molecules pass through the reverse osmosis membrane to produce pure water. At the same time, various impurities and harmful substances that cannot penetrate Substance is discharged with concentrated wastewater. [0003] At present, reverse osmosis technology has been widely used in water purification and other fields. Under normal operating conditions, the reverse osmosis membrane may be polluted by inorganic scale, colloid, microorganisms, metal oxides, etc. These substances are deposited on the membrane surface, which will cause a decrease in the output of reverse osmosis or a ...
