Abstract:
A hollow-fiber membrane module (101) that includes a housing (30) including a small-diameter part (3B) which has an inner diameter smaller than the inner diameter of a flow-guiding cylinder (9) facing the part of the housing (30) which has a nozzle (8) disposed, the small-diameter part (3B) having been disposed on the lower side of the lower end of the flow-guiding cylinder (9) in the axial direction of the hollow-fiber membrane module (101), or that includes a flow-guiding cylinder (9) including a small-diameter part (9G) which has an inner diameter smaller than the inner diameter of the part of the flow-guiding cylinder (9) which faces the part of a housing (30) which has a nozzle (8) disposed, the small-diameter part (9G) having been disposed on the lower side of the range where flow-guiding holes (10) are present, in the axial direction of the hollow-fiber membrane module (101).

Abstract:
A cartridge type hollow-fiber membrane module of the present invention includes: a housing; a plurality of hollow fiber membranes housed in the housing; a first potting part which bundles first ends of the hollow fiber membranes while keeping the first ends open; a second potting part which bundles second ends of the hollow fiber membranes while keeping the second ends sealed; a fixing part which detachably fixes the first potting part to the housing; a sealing part which liquid-tightly seals a space between the first potting part and the housing; and a holding part which holds the second potting part so that the second potting part is detachable from the housing and so that liquids can pass through a space between the second potting part and the housing.
Abstract:
A hollow-fiber membrane module of the invention includes: a cylindrical case having a first end and a second end in a height direction thereof; a hollow-fiber membrane bundle being housed in the cylindrical case and having a plurality of hollow-fiber membranes each closed at an end part on the first end side and opened at an end part on the second end side; a first binding part binding the end parts on the first end side of the hollow-fiber membranes; a first flow channel guiding fluid to pass through the first binding part from the first end side to the second end side of the first binding part; and a channel material directing, at a terminal on the second end side of the first flow channel, a flow of at least a part of the fluid flowing out from the terminal on the second end side of the first flow channel toward a direction intersecting the height direction of the cylindrical case.
