HOLLOW-FIBER MEMBRANE MODULE

摘要

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).
