Abstract

The invention relates to a multiple passage membrane pipe, which is characterized in that the penetration side is in said membrane pipe, and the outer surface of membrane pipe os used as raw material side or sealed, and the membrane component can be prepared without sealed shell cover. The new multiple passage membrane pipe possesses penetration side area and raw material side area on condition of same external dimension, which can increase availability ratio of membrane pipe surface area. The invention is used to separate membrane for membane component immersing into raw material fluid, and is characterized by simple production and low device cost.

Description

technical field

[0001] The invention relates to a multi-channel membrane tube and its application, in particular to a multi-channel membrane tube with high membrane surface area utilization efficiency and its application in an air-lift membrane treatment device. Background technique

[0002] The membrane device can realize the membrane filtration separation process of microfiltration and ultrafiltration, which is used to separate fluids containing macromolecules or large-sized particles. Solvents and small-molecule solutes in the fluid permeate the membrane, and macromolecules or large-sized particles are retained by the membrane. Compared with conventional filtration, membrane filtration has the characteristics of high filtration precision and energy saving.

[0003] In practical application, the membrane tube is mainly multi-channel, because the multi-channel membrane tube has a compact structure, a relatively large membrane area, and it is relatively easy to realize cross...
