Abstract
A hollow fiber membrane module 10 has a hollow fiber membrane bundle 11 and a housing case 15. The housing case 15 has first molding members 17 and a second molding member 18. At each first molding member, a tubular portion 19 and a nozzle portion 20 are integrally molded. The second molding member 18 has a tubular shape coaxially continuous from the tubular portion 19. Values obtained by dividing, by the wall thickness of the second molding member, the wall thicknesses of the housing case 15 at positions separated in the axial direction from a connecting position toward the first molding member 17 side by distances of 3 times and 5 times the wall thickness of the second molding member 18 are 1.0 to 1.3 and 1.0 to 1.5, respectively.
Claims9
A hollow fiber membrane module, comprising:
- a hollow fiber membrane bundle configured by bundling a plurality of hollow fiber membranes;
- and
- a housing case that has a first molding member formed by integrally molding a tubular portion and a nozzle portion with a lumen communicated with the tubular portion and a tubular second molding member coaxially continuous with the tubular portion and accommodates the hollow fiber membrane bundle, wherein
- a total length of the housing case in an axial direction exceeds 1 m;
- and
- values obtained by dividing, by a wall thickness of the second molding member, wall thicknesses of the first molding member at positions separated from a connecting position between the first molding member and the second molding member toward the first molding member side by distances of 3 times and 5 times the wall thickness of the second molding member in the axial direction are 1.10 to 1.3 and 1.17 to 1.5, respectively.
