liquid-solid separation system of hollow fiber membrane with turbulence caused by reciprocating swing motion of membrane bundle module

摘要

The present invention relates to an apparatus for separating and concentrating a bundle of bundles of hollow fiber membranes by reciprocating swing, which separates a composite material having various properties and compositions existing in a fluid by molecular weight or size. More specifically, The membrane module connected in bundle with the membrane separator is installed in the radial direction of the central rotary shaft, the lower header is fixed by the reciprocating swing rotation of the central rotary shaft, and the fluid is separated by the hollow fiber membrane while the upper header is reciprocatingly swinging The hollow fiber separation membrane is swirled by a reciprocating swing process to generate a swirling flow to uniform the fluid, and the hollow fiber separation membrane is twisted and rubbed against each other to maintain a constant permeation rate of the fluid, , Minimizing elements that interfere with membrane permeability, such as sedimentary solute layers It is possible to increase the membrane permeation efficiency without deteriorating the permeability of the membrane and to continuously operate the hollow fiber membrane without any separate cleaning operation, thereby lengthening the membrane cleaning cycle and prolonging the service life of the hollow fiber membrane.
