Abstract

The invention provides a reverse osmosis membrane element and a reverse osmosis water purification device which help to reduce costs and save installation space. The filter element of the reverse osmosis membrane element is formed by folding a composite layer in accordion fashion. The composite layer comprises leader cloth, a reverse osmosis membrane, a separating net, a reverse osmosis membrane, and leader cloth in sequence; wherein the reverse osmosis membrane, the separating net, and the reverse osmosis membrane form a water-producing flow passage. The position of the raw water inlet of the filter element and the position of the waste water outlet enable the water in the water-producing flow passage flows in a direction perpendicular to the folding direction of the accordion fashion. The reverse osmosis water purification device of the present invention is equipped with the reverse osmosis membrane element of the present invention.

Description

technical field [0001] The invention relates to water treatment technology, in particular to a reverse osmosis membrane element and reverse osmosis water purification equipment. Background technique [0002] The common application form of reverse osmosis technology in water treatment is to make a spiral-wound reverse osmosis membrane element, also known as a spiral-wound reverse osmosis membrane element, which has a central tube with multiple holes and a coil wound on the central tube. Alternately stacked multi-layer reverse osmosis membranes and diversion nets. It generally has a cylindrical pressure vessel as the shell, and the central pipe is connected with the two ends of the shell through connectors. [0003] During use, the raw water enters the reverse osmosis membrane element from one end of the shell. Under the action of pressure, part of the water becomes pure water after being filtered by the reverse osmosis membrane and enters the central tube and flows out from ...
