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] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It is the core component of reverse osmosis technology. After a period of use, the surface of the reverse osmosis membrane will be polluted, such as surface scaling and membrane blockage. At the same time, the compaction effect of the membrane causes the water permeability of the membrane to decrease. The pollution and blockage of the membrane are mainly caused by membrane surface deposition and the growth of microorganisms. Among them, microorganisms not only block the membrane, but also corrode and damage the cellulose acetate membrane. Excessive residual chlorine will cause the performance of the membrane to deteriorate. If these contaminants on the membrane surface are not removed regularly and in a timely manner, the membrane will be irreparably damaged and the normal water production and water quality of the membrane will be affected. Most of the existing reverse osmosis membrane cleaning devices are fixed and cannot be adaptively adjusted, and cannot meet the use requirements. Utility Model Content
