<P>PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module for moisture exchange, in which a dried oxidizing agent gas to be supplied into hollow fiber membranes can be humidified sufficiently and the wetted off-gas can be caused to uniformly flow while suppresing deviation of the packed hollow fiber membranes. <P>SOLUTION: The hollow fiber membrane module for moisture exchange includes: a cylindrical case; a plurality of hollow fiber membranes packed extending in an axial direction, in the space of the cylindrical case; seal parts for fixing the hollow fiber membranes at both ends of the cylindrical case and sealing the spaces at both ends thereof; an introduction port arranged on one side face of the cylindrical case; a discharge port arranged on the side face opposed to the introduction port-arranged side face; a first fluid route formed from one end side of the hollow fiber membrane to the other end side thereof via the inside of the hollow fiber membrane; a second fluid route formed from the introduction port to the discharge port via the inside of the space being the outside of the hollow fiber membrane; and a plurality of partition plates which are extended in the space and arranged in parallel to the side face of the cylindrical case where the introduction port and the discharge port are arranged. Each of the plurality of partition plates has an opening. The space between the cylindrical case and the partition plate, which is one of the plurality of partition plates and is arranged on the introduction port side, is made narrower than any of the space between the adjacent partition plates and the space between the cylindrical case and the partition plate arranged on the discharge port side. <P>COPYRIGHT: (C)2011,JPO&INPIT |
