Description

Technical Field

[0001] The utility model belongs to the technical field of RO membranes, in particular to an RO membrane structure with high interception capacity. Background Art

[0002] RO is a reverse osmosis membrane. Generally, water flows from low concentration to high concentration. Once water is pressurized, it will flow from high concentration to low concentration, which is the so-called reverse osmosis principle. Since the pore size of the RO membrane is one millionth of a hair (0.0001 micron), it is generally invisible to the naked eye. Bacteria and viruses are 5000 times larger than it. Therefore, the RO membrane has a very high interception capacity. Only water molecules and some mineral ions can pass through (the ions passing through have no benefit or loss orientation). Other impurities and heavy metals are discharged from the wastewater pipe. Existing patent (Announcement No.: CN211688525U ) A reverse osmosis membrane structure of a water purification device, the reverse osmosis membrane structure is convenient for protecting the reverse osmosis membrane body and filtering the water inlet and outlet ends of the reverse osmosis membrane body through a fixed filter net, thereby avoiding a large amount of impurities remaining at both ends of the reverse osmosis membrane due to long-term use, thereby reducing the water purification efficiency of the reverse osmosis membrane; through a fixed filter tube, it is convenient to take out the filter net for cleaning, thereby avoiding damage to the performance of the reverse osmosis membrane due to untimely cleaning; however, the RO membrane body in the RO membrane structure is very inconvenient to replace, which increases the difficulty of replacement for operators and reduces work efficiency.
