Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane concentration equipment, specifically a high-pressure reverse osmosis membrane concentration equipment. Background Technology

[0002] Reverse osmosis membrane concentration equipment is used to concentrate liquids through reverse osmosis. It allows for liquid screening and control. The reverse osmosis membrane is an artificial semi-permeable membrane with specific characteristics, mimicking a biological semi-permeable membrane, and is the core component of reverse osmosis technology. The reverse osmosis membrane consists of a 0.1–0.3 μm thick skin layer (dense layer) and a 100–300 μm thick porous support layer. The principle of reverse osmosis technology is based on the principle that under pressure higher than the osmotic pressure of the solution, other substances cannot pass through the semi-permeable membrane, thus separating them from water. The membrane pore size of the reverse osmosis membrane is extremely small, therefore it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water. The system has advantages such as good water quality, low energy consumption, no pollution, simple process, and easy operation.

[0003] For example, the authorized patent with publication number CN213012094U (Two-End Reverse Osmosis Membrane Concentration Assembly Device) includes a horizontal tube, with supports fixed to the top and bottom left and right sides of the horizontal tube. A threaded rod is fitted inside the support, and a first ring is fitted to the outer wall of the threaded rod. A nut is threaded onto the right side of the outer wall of the threaded rod. This two-end reverse osmosis membrane concentration assembly device facilitates the connection and disassembly of the reverse osmosis membrane, thus avoiding the problem in existing reverse osmosis membrane concentration assemblies where disassembly is difficult during membrane replacement, causing significant work difficulties for operators. Furthermore, this two-end reverse osmosis membrane concentration assembly device allows filtration from both sides, improving filtration efficiency and reducing the work cycle. Therefore, this two-end reverse osmosis membrane concentration assembly device fully meets people's needs.

[0004] The aforementioned existing concentration equipment is inconvenient to carry by hand, and it is not convenient to separate the liquid inflow and the concentrated liquid and filtrate for discharge. It is not flexible enough to use, and the concentrated liquid is not convenient to collect or circulate for purification. Furthermore, the single-layer concentration control is not thorough enough for controlling the concentration of the liquid. Utility Model Content
