Abstract

A hollow fiber membrane module in which a housing body forming the hollow fiber membrane module includes an insertion opening into which end parts of the plurality of hollow fiber membranes are inserted so as to be fixed and held, and an opening portion which exposes open end surfaces of a plurality of hollow fiber membranes inserted from the insertion opening to outside, and a cover that blocks the opening portion of the housing body. According to the present invention, it is possible to provide a housing enabling open end surfaces of hollow fiber membranes to be sealed by easily exposing the open end surfaces of the hollow fiber membranes when the hollow fiber membranes are damaged.

First claim

The invention claimed is:

1. A hollow fiber membrane module, comprising:
a plurality of hollow fiber membranes that are arranged in a sheet form;
a housing that fixes the hollow fiber membranes and comprises a housing body and a cover; and
a pair of fastening members that are configured to fasten a joining portion between the housing body and the cover and extend in a width direction of the hollow fiber membrane module,
wherein
each of the fastening members comprises a groove extending in a longitudinal direction of the fastening member, where a width of the groove increases toward inside of the groove,
each of the housing body and the cover comprises guide portions configured to fit the groove when being covered by the fastening member,
the guide portion of the housing body and the guide portion of the cover have different shapes,
the groove comprises a flat bottom, a tilt surface, and a stepwise surface,
the guide portion of the housing body is configured to contact at least a part of the flat bottom and the stepwise surface of the groove,
the guide portion of the cover is configured to contact at least a part of the flat bottom and the tilt surface of the groove,
the housing body comprises
an insertion opening into which end parts of the plurality of hollow fiber membranes are inserted and sealed by a fixing resin, and
an opening portion formed in a longitudinal direction of the plurality of hollow fiber membranes to enable maintenance of open end surfaces of the plurality of hollow fiber membranes,

the cover openably and closeably covers the opening portion of the housing body,
the opening portion of the housing body is formed in the longitudinal direction along the housing, and
the opening portion of the housing body exposes the entire open end surfaces of at least one side of the plurality of hollow fiber membranes.

2. The hollow fiber membrane module according to claim 1 , wherein each of the guide portions of the cover and the housing body has a shape of which a width increases toward an outside of the guide portion.

3. The hollow fiber membrane module according to claim 2 , wherein the fastening member is divided into two or more pieces in the longitudinal direction of the fastening member.

4. The follow fiber membrane module according to claim 3 , wherein the housing further comprises a seal member between the guide portion of the housing body and the guide portion of the cover.

5. The follow fiber membrane module according to claim 4 , wherein the seal member comprises a rubber or an elastomer.

6. The follow fiber membrane module according to claim 5 , wherein the seal member comprises a silicone rubber, a fluorine rubber, or an acrylonitrile butadiene rubber.

7. The follow fiber membrane module according to claim 2 , wherein the housing further comprises a seal member between the guide portion of the housing body and the guide portion of the cover.

8. The hollow fiber membrane module according to claim 7 , wherein the fastening member is divided into two or more pieces in the longitudinal direction of the fastening member.

9. The follow fiber membrane module according to claim 7 , wherein the seal member comprises a rubber or an elastomer.

10. The follow fiber membrane module according to claim 9 , wherein the seal member comprises a silicone rubber, a fluorine rubber, or an acrylonitrile butadiene rubber.

11. The hollow fiber membrane module according to claim 1 , wherein the fastening member is divided into two or more pieces in the longitudinal direction of the fastening member.

12. The follow fiber membrane module according to claim 11 , wherein the housing further comprises a seal member between the guide portion of the housing body and the guide portion of the cover.

13. The follow fiber membrane module according to claim 12 , wherein the seal member comprises a rubber or an elastomer.

14. The follow fiber membrane module according to claim 13 , wherein the seal member comprises a silicone rubber, a fluorine rubber, or an acrylonitrile butadiene rubber.

15. The follow fiber membrane module according to claim 1 , wherein the housing further comprises a seal member between the guide portion of the housing body and the guide portion of the cover.

16. The follow fiber membrane module according to claim 15 , wherein the seal member comprises a rubber or an elastomer.

17. The follow fiber membrane module according to claim 16 , wherein the seal member comprises a silicone rubber, a fluorine rubber, or an acrylonitrile butadiene rubber.

18. The follow fiber membrane module according to claim 1 , wherein the guide portion of the cover has a chamfered portion.

19. The hollow fiber membrane module according to claim 18 , wherein the fastening member is divided into two or more pieces in the longitudinal direction of the fastening member.
