Processing technology of hollow fiber membrane module

Abstract

The invention discloses a processing technology of a hollow fiber membrane module, which comprises the following steps: S1, prepartion of materials, comprising winding: arranging a substrate strip onthe side wall of a roller for winding, partially covering the side wall of the roller by the substrate strip, and spirally winding hollow fiber membrane filaments on the roller to form a single winding layer; connection: connecting the winding layer and the substrate strip together; and cutting: cutting the winding layer and the substrate strip at the joint of the winding layer and the substrate strip to obtain a membrane with the substrate strips at the two ends, and connecting any end of the hollow fiber membrane silk on the membrane to the corresponding substrate strip; S2, case mounting: stacking a plurality of membranes in sequence, inserting one end of each membrane into one end membrane shell, and inserting the other end of each membrane into the other end membrane shell, wherein itis guaranteed that the ends of the membranes extend out of the end membrane shells; S3, glue pouring: pouring glue into the interior of the end membrane shell, and conducting standing solidification;and S4, cutting: cutting the end part, extending out of the end membrane shell, of the membrane to obtain the hollow fiber membrane module.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a processing technology of a hollow fiber membrane module. Background technique [0002] In traditional hollow fiber membrane modules, the ends of several hollow fiber membranes are generally put into the end membrane shell, and the ends of the hollow fiber membranes are encapsulated in the through end membrane shell by filling glue. Finally, the end of the hollow fiber membrane is cut to ensure that the opening of the end of the hollow fiber membrane is not blocked. However, during the process of putting the end of the hollow fiber membrane into the end membrane shell, the hollow fiber There will be crossing and entanglement between the hollow fiber membrane modules, which will cause the hollow fiber membrane modules to easily deposit or stick pollutants on the hollow fiber membrane filaments during the subsequent use process, thus affecting the service life of the holl...
