Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a reverse osmosis membrane cleaning device. Background Art

[0002] In the prior art, the reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membranes, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of a pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation. In the prior art, the reverse osmosis membrane will be contaminated by inorganic salt scale, colloids, microorganisms, metal oxides, etc. after use. These substances are deposited on the membrane surface, which will cause the output of the reverse osmosis device to decrease or the desalination power to decrease. In addition, when cleaning the reverse osmosis membrane, it is usually controlled by staff to clean it, which greatly increases the workload.

[0003] Therefore, the present application proposes a reverse osmosis membrane cleaning device to solve the above problems. Utility Model Content
