Problems solved by technology

[0002] The existing ultrafiltration membrane filtration technology cannot meet the life requirements of the combined ultrafiltration membrane and post-filter material. Under the same volume, the area of ​​the ultrafiltration membrane is small, or the built-in functional filter material has insufficient filtration surface area and the filter wall thickness is too thick , resulting in composite filter life can not meet product requirements
Moreover, in the existing filtration technology, the ultrafiltration membrane area is small under the same volume, or the built-in functional filter material has insufficient filtration surface area, resulting in the life of the composite filter element not meeting the product requirements.

Abstract

The invention discloses a composite filter element with an ultrafiltration membrane. The composite filter element comprises a shell, and a first-stage filter element, an ultrafiltration membrane filter element and a rear functional filter element are sequentially arranged in the shell in the water flow direction. The ultrafiltration membrane filter element comprises a body, the body comprises an outer cylinder and an inner cylinder which are arranged inside and outside, an annular cavity is formed between the inner periphery of the outer cylinder and the outer periphery of the inner cylinder,ultrafiltration membrane wires are arranged in the annular cavity, and a first water inlet is formed in the peripheral wall of the outer cylinder. The composite filter element has the advantage of being long in service life.

Description

technical field [0001] The invention relates to a composite filter core with an ultrafiltration membrane. Background technique [0002] The existing ultrafiltration membrane filtration technology cannot meet the life requirements of the combined ultrafiltration membrane and post-filter material. Under the same volume, the area of ​​the ultrafiltration membrane is small, or the built-in functional filter material has insufficient filtration surface area and the filter wall thickness is too thick , resulting in composite filter life can not meet the product requirements. Moreover, in the existing filtration technology, the area of ​​the ultrafiltration membrane is small under the same volume, or the filtration surface area of ​​the built-in functional filter material is not enough, resulting in that the service life of the composite filter element cannot meet the product use requirements. Contents of the invention [0003] In order to solve the above technical problems, the...
