Membrane element, filter element and water purification device

By designing two raw water inlets in the membrane element, diversion into the membrane, thereby reducing impurity deposition near the long side, extending the service life of the membrane element and increasing the overwater flow, the serious problem of impurity deposition in the membrane near the raw water inlet in the membrane element is solved.

AI Technical Summary

Technical Problem

The membrane impurities near the long side of the raw water inlet in the membrane element are severely deposited, resulting in a short service life of the membrane element.

Method used

A membrane element is designed in which water enters from two raw water inlets (first raw water inlet and second raw water inlet), and flows out from the water purification outlet from the first side through the base diaphragm to the second side. The second raw water inlet is located on the first short side or the second short side of the base diaphragm, and the shunt reduces the flow of filtered water near the long side of the first raw water inlet and reduces the amount of impurity deposition.

Benefits of technology

Through the split design, the amount of impurity deposited in the base diaphragm near the long side of the first raw water inlet is reduced, the service life of the membrane element is extended, and the overwater flow rate is increased when filtering the same volume of water.

Abstract

The utility model discloses a membrane element, filter element and water purification plant, relates to water treatment technical field, membrane element includes: can be wound into the basic membrane element, the basic membrane under the unfold state has first short side, second short side, first long side and second long side, basic membrane has first face and second face, and the first face and second face have first face and second face. The two first surfaces or the two second surfaces of the adjacent basic membranes are opposite at intervals, a first raw water inlet is formed in the first long edge side of the two adjacent basic membranes with the opposite first surfaces, and a second raw water inlet is formed in the first short edge side or the second short edge side of the two adjacent basic membranes with the opposite first surfaces; and a purified water outlet is formed on the second long edge side of the two adjacent basic membranes with opposite second surfaces. The problem that the service life of the membrane element is short due to the fact that impurities of the basic membrane near the long side serving as the raw water inlet in the membrane element are severely deposited can be solved.
