Abstract

The invention relates to a multi-channel membrane tube, which is characterized in that the permeate side is in the multi-channel of the membrane tube, and the outer surface of the membrane tube is used as the raw material side or closed, and can be used as a membrane module without adding a closed shell-shaped jacket. In the case of the same external dimensions, the multi-channel membrane tube of the novel structure can have different ratios of the permeate side area and the raw material side area, thereby improving the utilization efficiency of the surface area of ​​the membrane tube. It is applied to the process of immersing the membrane element or membrane module in the raw material fluid for membrane separation, and has the characteristics of simple manufacture and low equipment 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...
