Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a backwashing energy storage core of a reverse osmosis water purifier. Background Art

[0002] When the RO reverse osmosis water purifier is working, the crystals produced by the attachments and minerals in the concentrated water in the membrane chamber pass through the membrane roll layer flow channel and adhere to the surface of the membrane and the micropores of the membrane, causing blockage. As the RO reverse osmosis water purifier works for a long time, a crystal layer is formed, which seriously affects the water production, and in more serious cases, it will cause complete blockage.

[0003] Due to the implementation of environmental protection resource requirements and water efficiency, urban tap water is now widely used with surface water. After disinfection, the microorganisms contained in the tap water are killed and reach the safe drinking standard. However, the corpses of microorganisms remain in the water. During the long-term operation of the reverse osmosis water purifier, the corpses of microorganisms will adhere to the surface of the membrane to form a microbial colloid film layer, which seriously affects the water production and water quality of the RO membrane. When the RO reverse osmosis water purifier is working, the flowing water flow is the reverse osmosis working phenomenon. However, when the RO reverse osmosis water purifier stops working, the long-term static osmosis is the forward osmosis working phenomenon. The forward osmosis phenomenon will cause the TDS value of the water produced by the RO water purifier to be too high when it works again, affecting the water quality, and causing the problem of clogging of the RO membrane of the water purifier. Utility Model Content
