Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane equipment technology, specifically to a reverse osmosis membrane device with a highly efficient sterilization structure. Background Technology

[0002] A reverse osmosis membrane is a polymeric thin film with selective separation capabilities. Driven by applied pressure, it allows water molecules to pass through while retaining dissolved salts, organic matter, microorganisms, and other impurities, thereby achieving desalination, purification, or concentration of a solution. Its core principle is reverse osmosis, which forces water molecules to permeate from a high-concentration solution (such as seawater) to a low-concentration side by applying pressure higher than the solution's osmotic pressure, achieving separation.

[0003] Chinese utility model patent CN217323723U discloses a reverse osmosis membrane device with a highly efficient sterilization structure, which includes "a number of filter plates 12 are fixedly connected at equal intervals on the left and right sides of the front plate 9, and a number of filter sheets 13 are arranged at equal intervals inside the filter plates 12. The filter sheets 13 can be made of water filtration materials such as quartz sand, resin, and activated carbon. The filter sheets 13 can play a preliminary filtration role for the water. A number of installation boxes 14 are fixedly connected at equal intervals on both the left and right sides of the front side inside the outer shell 1. A number of ultraviolet sterilization lamps 16 are fixedly connected at equal intervals inside the installation boxes 14. The ultraviolet sterilization lamps 16 can irradiate and sterilize the water that has been preliminarily filtered. An activated carbon filter box 17 is fixedly connected to the lower side inside the outer shell 1. The activated carbon filter box 17 can be filled with various forms of activated carbon or other substances that effectively adsorb chlorine." However, the fixedly connected filter plates and filter sheets in this device are inconvenient to replace and maintain. Utility Model Content
