MEMBRANE DISTILLATION MODULE AND MEMBRANE DISTILLATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/111158
Kind Code:
A1
Abstract:
Provided is a membrane distillation module 100 comprising a membrane distillation membrane cartridge 10 and a membrane distillation housing 20, wherein: the membrane cartridge 10 comprises a membrane anchoring part 12 in which porous membranes 11 are anchored by anchoring resin; the housing 20 comprises a housing body 30 and a housing lid 40; the membrane distillation module 100 comprises a support part 60 where the outer surface of the membrane anchoring part 12 is supported by the inner surface of the housing 20 with a seal member 50 interposed therebetween; and a value C in the cross section of the support part 60 is at least 30°C as represented by the following formula, where dF is the equivalent circular diameter (mm) of the outer circumference of the membrane anchoring part 12, kF is the linear expansion coefficient (1/℃) of the anchoring resin, dE is the equivalent circular diameter (mm) of the inner circumference of the housing 20, and kE is the linear expansion coefficient (1/°C) of a portion where the housing 20 contacts the seal member 50.
