DEHUMIDIFYING HOLLOW-FIBER MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a dehumidifying hollow-fiber membrane module improved in the dehumidifying effect by more uniformly supplying a sweep gas to each hollow-fiber membrane of a hollow-fiber bundle. SOLUTION: Both ends of the hollow-fiber bundle consisting of plural hollow- fiber membranes 2 are opened and fixed to a housing 1 with a potting agent, and an inlet for a gas to be dehumidified is formed on one end of the bundle and an outlet for the dehumidified gas on the other end to constitute the module. Further, a sweep gas feed porous tube 3 with the end opened only at the potting part 6 on the dehumidified gas outlet side is dispersed in the hollow-fiber bundle.
