Ceramic hollow fibre membrane module

摘要

A fluid filter membrane module comprises a tubular housing containing a spiral array of porous ceramic fine fibers with a hollow core discharging to a collection point. The housing receives a pressurized supply of a fluid mixture whose finer components permeate under pressure into the fine ceramic tube core. The module housing and fine ceramic fibers have the same coefficient of thermal expansion. The module housing is a flexible metal, plastic or rubber. The fiber pitch length is 0.5-10 times the fiber outer diameter. The spiral inner diameter is at least 20 mm. The module contains a multitude of spiral fibers.
