Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a novel reverse osmosis membrane component. Background Technology

[0002] Reverse osmosis technology is one of the most mainstream desalination and water purification technologies, and its core is the reverse osmosis membrane module.

[0003] For example, in Chinese patent application CN202220430745.1, a novel reverse osmosis membrane module is described. Its features include a reverse osmosis membrane element, a membrane module connector, and a concentrate collection device. Two membrane module connectors are symmetrically installed at both ends of the reverse osmosis membrane element. Each membrane module connector has a placement cavity containing the concentrate collection device. The concentrate collection device includes a collection shell that contacts the placement cavity. Twelve support ribs are symmetrically fixed to the center of the outer periphery of the collection shell. Each support rib has five symmetrically arranged through holes. A pure water through hole is provided inside the collection shell, connecting to the collection cavity, but the pure water through hole is not connected to the collection cavity. This invention, through the design of the reverse osmosis membrane element, membrane module connector, and concentrate collection device, allows the rotating ring to drive the baffle to rotate. When the baffle stops compressing the sponge, the collection port opens, allowing the concentrate in the concentrate outlet to flow into the collection cavity and be absorbed by the sponge, thus preventing residual concentrate from contaminating the pure water.

[0004] While the above-mentioned solutions have the advantages mentioned above, they also have disadvantages: the inlet channel design is unreasonable, which leads to salt accumulation on the membrane surface, reducing the desalination rate. At the same time, they are prone to fouling, with suspended solids, colloids, and microorganisms accumulating on the inlet side, causing membrane pore blockage and requiring frequent cleaning. Additionally, leakage is prone to occur at the connection between the end cap and the membrane housing, affecting the stability of the system. Utility Model Content
