Ceramic nanofiltration membrane assembly for water purifier

Abstract

The invention discloses a ceramic nanofiltration membrane assembly for a water purifier. The ceramic nanofiltration membrane assembly comprises a shell, a ceramic nanofiltration membrane filter element and an upper cover which are arranged in the shell, the upper cover is provided with a water inlet, a water outlet and a concentrated water outlet, the ceramic nanofiltration membrane filter elementis internally provided with a plurality of filtration channels and water purification channels, the water purification channels are enclosed plate-shaped cavities, the outer wall face of the ceramicnanofiltration membrane filter element is provided with a plurality of water outlet grooves, a water inlet cavity is formed between the inner wall of the upper cover and the upper end face of the ceramic nanofiltration membrane filter element, a water outlet cavity is formed between the inner wall of the shell, the outer wall of the ceramic nanofiltration membrane filter element and the water outlet grooves, and a concentrated water cavity is formed between the bottom of the shell and the lower end face of the ceramic nanofiltration membrane filter element. The filter element is the ceramic nanofiltration membrane filter element, compared with a method of a coating in the past, the service life is longer, and the filtration effect is better; by arranging the purification channels in the ceramic nanofiltration membrane filter element, filtration areas are larger, pressure of the filtration wall is even, and during use for a long time, crack on the ceramic nanofiltration membrane filterelement is not prone to being formed.

Description

technical field [0001] The invention relates to a ceramic nanofiltration membrane assembly for a water purifier. Background technique [0002] With the advancement of industrialization, the problem of environmental pollution is becoming more and more serious, especially the problem of water resource pollution. However, there are problems such as the lag in the improvement of waterworks and equipment, the corrosion of urban water supply pipe networks, the deposition of sediment in water, and the unsafety of secondary water supply. The terminal purification of water resources has received more attention, and the safety of drinking water has attracted more and more attention. The water purifier is a water treatment device that intercepts suspended colloids, heavy metals, microorganisms, viruses, bacteria and other substances in raw water through the principle of physical filtration, and allows water molecules and other ions to pass through. [0003] At present, most water puri...

AI Technical Summary

Problems solved by technology

The existing tubular ceramic nanofiltration membrane only relies on the dense micropores on the tube wall to carry out the filtrate during the filtration process, while the macromolecular substances or suspended solids in the raw water are easily attached to the tube wall, causing the micropores to be blocked, resulting in a poor filtration effect. bad

Moreover, since the interior of the tubular ceramic nanofiltration membrane is under pressure for a long time, cracks are prone to occur, so there is a common problem of short service life.
