A RO reverse osmosis membrane filtration purification filter element fixing system

Abstract

The invention relates to an RO reverse osmosis membrane filtration and purification filter element, which includes a liquid inlet unit, a limiting unit and a liquid outlet unit. The unit and the liquid outlet unit are symmetrically arranged, and the liquid inlet unit and the liquid outlet unit are both tapered structures; the present invention can solve the problem of RO reverse osmosis membrane filtration and purification When the filter element is fixed and when the water pipe is connected: it needs to be assisted to place and straighten the RO reverse osmosis membrane filter purification filter element before it can be fixed together, which increases the labor cost; because the RO reverse osmosis membrane needs to be placed in sequence The liquid inlet and liquid outlet of the filtration and purification filter element are connected to water pipes, which leads to an increase in the use of water pipes, increases the cost of purchasing water pipes, and increases the time for laying water pipes, 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
