RO reverse osmosis membrane filtration and purification filter element

Abstract

The invention relates to an RO reverse osmosis membrane filtration and purification filter element. The RO reverse osmosis membrane filtration and purification filter element comprises a liquid inletunit, a limiting unit and a liquid outlet unit; the limiting unit is installed on the lower end of the liquid inlet unit; the liquid outlet unit is installed on the lower end of the limiting unit; furthermore, the liquid inlet unit and the liquid outlet unit are symmetrically arranged; and both the liquid inlet unit and the liquid outlet unit are tapered structures. The RO reverse osmosis membranefiltration and purification filter element in the invention can solve the following problems existing when the RO reverse osmosis membrane filtration and purification filter elements are fixed and connected with water pipes in a scene that multiple RO reverse osmosis membrane filtration and purification filter elements need to be used: the RO reverse osmosis membrane filtration and purification filter elements can be fixed together only after being placed and righted in an assisted manner, so that the human cost is increased; because the liquid inlets and the liquid outlets of the RO reverseosmosis membrane filtration and purification filter elements need to be connected with the water pipes in sequence, the use amount of the water pipes is increased; the water pipe purchasing cost is increased; furthermore, the time for laying the water pipes is increased, etc.

Description

technical field [0001] The invention relates to the technical field of water quality purification treatment, in particular to an RO reverse osmosis membrane filtration purification filter element. Background technique [0002] Reverse osmosis membranes are widely used in electric power, petrochemical, steel, electronics, medicine, food and beverage, municipal and environmental protection and other fields, in seawater and brackish water desalination, boiler feed water, industrial pure water and electronic grade ultrapure water preparation, pure drinking It plays an important role in water production, wastewater treatment and special separation process, and RO reverse osmosis membrane is a kind of reverse osmosis membrane; [0003] In some scenarios where multiple RO reverse osmosis membrane filtration purification filter elements are required, usually multiple RO reverse osmosis membrane filtration purification filter elements are fixed together, or a single RO reverse osmosi...

AI Technical Summary

Problems solved by technology

[0004] 1. When fixing multiple RO reverse osmosis membrane filtration and purification filter elements together, because the appearance of the RO reverse osmosis membrane filtration purification filter element is cylindrical and the number is large, it is necessary to be assisted to swing the RO reverse osmosis membrane filtration purification filter element It can only be fixed together after being placed and righted, which increases the labor cost; while fixing a single RO reverse osmosis membrane filtration purification filter element in turn increases the time for fixing the RO reverse osmosis membrane filtration purification filter element, and due to RO The reverse osmosis membrane filtration purification filter element is not fixed together, which wastes the space required for fixing the RO reverse osmosis membrane filtration purification filter element;

[0005] 2. Due to the need to connect the liquid inlet and outlet of the RO reverse osmosis membrane filtration and purification filter element to the water pipe in sequence, the usage of the water pipe increases, the cost of purchasing the water pipe is increased, and the cost of laying the water pipe is increased. time, thereby reducing the efficiency of laying water pipes
