Abstract

A hollow fiber membrane module includes a housing having an inlet formed one end thereof and an outlet formed on the other end thereof, in which hot and humid humidifying fluid flows in through the inlet and the humidifying fluid after humidifying a cool and dry fluid flowing out of the housing through the outlet; at least one hollow fiber membrane bundle which is inserted into the housing in the longitudinal direction; a partitioning part for supporting the hollow fiber membrane bundle and partitioning an inflow space, in which the humidifying fluid flowing into the housing momentarily remains, and an outflow space, in which the humidifying fluid momentarily remains before being discharged through the outlet; and a potting part for potting both ends of the hollow fiber membrane bundle to the housing.

First claim

1 . A hollow fiber membrane module comprising:
a housing provided with an inlet formed at one end thereof and an outlet formed at the other end thereof, a hot and humid humidifying fluid flowing into the housing through the inlet and the humidifying fluid after humidifying a cool and dry fluid flowing out of the housing through the outlet; at least one hollow fiber membrane bundle inserted into the housing in a length direction of the housing; a partitioning part configured to support the at least one hollow fiber membrane bundle and to partition the interior of the housing into an inflow space, in which the humidifying fluid flowing into the housing momentarily resides, and an outflow space, in which the humidifying fluid momentarily resides before being discharged to the outside of the housing through the outlet; and potting parts configured to pot both ends of the at least one hollow fiber membrane bundle to the housing.

2 . The hollow fiber membrane module according to claim 1 , wherein a size of the inflow space is equal to or greater than a size of the outflow space.

3 . The hollow fiber membrane module according to claim 1 , wherein hollow fiber membrane cartridges, potted together with the at least one hollow fiber membrane bundle to the housing at once, are placed on both ends of the at least one follow fiber membrane bundle.

4 . The hollow fiber membrane module according to claim 3 , wherein vacant cartridges, inserted into the partitioning part without hollow fiber membrane bundles and potted to the housing at once, are additionally provided within the housing according to a humidifying capacity or a humidification degree.

5 . The hollow fiber membrane module according to claim 4 , wherein the vacant cartridges have a circular, oval or polygonal cross-section and are closed so that no fluid flows into an insertion space of the partitioning part.

6 . The hollow fiber membrane module according to claim 3 , wherein fluid passage parts are formed on the hollow fiber membrane cartridges so as to allow the fluid to easily flow into the at least one hollow fiber membrane bundle.

7 . The hollow fiber membrane module according to claim 3 , wherein the at least one hollow fiber membrane bundle in the hollow fiber membrane cartridges comprises 30 to 60% by volume of hollow fiber membranes with respect to a whole volume thereof.

8 . The hollow fiber membrane module according to claim 3 , wherein the hollow fiber membrane cartridges have a circular, oval or polygonal cross-section.

9 . The hollow fiber membrane module according to claim 3 , wherein a ratio of an equivalent diameter to a length of the at least one hollow fiber membrane bundle in the hollow fiber membrane cartridges is 1:2˜1:20.

10 . The hollow fiber membrane module according to claim 3 , wherein a wall thickness of the hollow fiber membrane cartridges is 10 mm or less.

11 . The hollow fiber membrane module according to claim 3 , wherein windows are formed on side walls of bodies of the hollow fiber membrane cartridges formed in the length direction of the housing so as to allow the hot and humid humidifying fluid to flow into the hollow fiber membrane cartridges.

12 . The hollow fiber membrane module according to claim 11 , wherein fluid passage parts are formed on the hollow fiber membrane cartridges so as to allow the fluid to easily flow into the at least one hollow fiber membrane bundle,
wherein a size of the windows is equal to or smaller than a size of the fluid passage parts.
