Abstract:
1. A hollow fiber membrane module comprising: a hollow fiber membrane bundled body that contains a rectangular parallelepiped hollow fiber membrane bundle having plural hollow fiber membranes bundled together, and the hollow fiber membrane bundled body has an outer periphery formed into a cylindrical shape along the entire length direction thereof; an outer chassis that has a cylindrical part enclosing the hollow fiber membrane bundled body, and an inner periphery of the cylindrical part being formed into a cylindrical shape along the entire length direction thereof; a first flow path that is formed by utilizing the outer chassis, introduces a first fluid into a hollow part of the hollow fiber membranes at one end of the hollow fiber membrane bundled body, and discharges the first fluid from the hollow part of the hollow fiber membranes at the other end of the hollow fiber membrane bundled body; a second flow path that is formed by utilizing the outer chassis, introduces a second fluid into a space among the hollow fiber membranes on a side surface of the hollow fiber membrane bundled body, and discharges the second fluid from the space among the hollow fiber membranes on a side surface of the hollow fiber membrane bundled body; and an annular sealing member that is provided between the outer periphery of the cylindrical shape of the hollow fiber membrane bundled body and the inner periphery of the cylindrical part of the outer chassis, to seal between a side of the first flow path and a side of the second flow path, a fluid component being transported between the first fluid and the second fluid through the hollow fiber membranes, wherein a rectangular perforated partition plate that expands the second fluid in the cylindrical axial direction to guide it to the side surface of the hollow fiber membrane bundle is provided in the second flow path, wherein the hollow fiber membrane bundled body has an inner chassis having a cylindrical part enclosing the hollow fiber membrane bundle from the side thereof, and the cylindrical part of the inner chassis is formed to have a cylindrical outer periphery along the entire length direction thereof, wherein the second flow path has a second inlet flow path that penetrates a side wall of the inner chassis at a certain position in the length direction thereof and introduces the second fluid into the side surface of the hollow fiber membrane bundle, and a second outlet flow path that penetrates the side wall of the inner chassis at another position in the length direction thereof and discharges the second fluid from the side surface of the hollow fiber membrane bundle, and further has an annular sealing member that is provided between an outer periphery of the cylindrical part of the inner chassis and an inner periphery of the cylindrical part of the outer chassis and seals between a side of the second inlet flow path and a side of the second outlet flow path, and wherein the second inlet flow path that penetrates the side wall of the inner chassis is formed as a through-hole with a rectifying lattice.
