Reverse osmosis membrane filter element based on membrane separation technology

Abstract

The invention provides a reverse osmosis membrane filter element based on a membrane separation technology. The reverse osmosis membrane filter element comprises a fixing device, core rods, a water inlet unit and a water outlet unit, wherein the core rods are uniformly mounted in the fixing device; the water inlet ends of the uniformly arranged core rods are in fixed communication through the water inlet unit; the water outlet unit is mounted on the outer wall of the lower end of the fixing device; and the water outlet unit communicates with the water outlet end of each core rod. The problemsthat in a parallel mounting process of existing reverse osmosis membrane filter elements, the water filtering effect of the core rods is affected as the core rods are prone to shaking in a fixing andmounting process, and the water filtering efficiency of the core rods is affected as water inflow is uneven due to the fact that the multiple core rods fixed in parallel are adopted at present are solved.

Description

technical field [0001] The invention relates to the technical field of water quality purification, in particular to a reverse osmosis membrane filter element based on membrane separation technology. Background technique [0002] The filter element is to clean the polluted water to the state required for production and life, that is, to make the water reach a certain degree of cleanliness. Remove solid particles in water, kill bacteria, and filter out harmful chemical components. Common materials for reverse osmosis membrane filters are nitrocellulose, cellulose acetate and polyamide. Among them, the reverse osmosis membrane filter uses the selective permeability of the reverse osmosis membrane to only pass through the solvent (usually water) and intercept ionic substances or small molecular substances, and uses the static pressure on both sides of the membrane as the driving force to separate the liquid mixture. membrane process. [0003] The current reverse osmosis membr...

AI Technical Summary

Problems solved by technology

[0003] The current reverse osmosis membrane filter elements are mostly installed inside the water purifier, but the current water purifier usually needs to install multiple reverse osmosis membrane filter elements in parallel. The following problems mainly exist in the process of parallel installation of the current reverse osmosis membrane filter elements: It is easy to shake during the fixed installation of the rod, which will affect the water filtration effect of the mandrel, and the multiple parallel fixed mandrels currently used lead to uneven water inflow, which affects the water filtration efficiency of the mandrel
