<P>PROBLEM TO BE SOLVED: To uniform a flow of gas in a module case interior. <P>SOLUTION: In a hollow fiber module 10, its outer circumference part is covered by a housing 20 in a state with a plurality of bundles of hollow fiber membranes 12 housed in a cylindrical module case 11. A gas introducing part 30 introduces gas into a space between the housing 20 and the module case 11. In such a case, the module case 11 plurally has gas inlets 14 for sending the gas into the interior of the module case 11 along a circumferential direction of the module case 11. In each of the gas inlets 14, an opening area becomes smaller as a position in the circumferential direction of the module case 11 becomes separated from a gas introducing part 30 side. <P>COPYRIGHT: (C)2007,JPO&INPIT |
