Patent number: 11701620Abstract: An external circulation-type hollow fiber membrane module which has a high processing capacity and which is capable of inhibiting a to-be-treated liquid within a case from flowing through a short path and efficiently bringing the liquid into contact with a hollow fiber membrane in whichever direction of a vertical direction, a horizontal direction, etc., the liquid flows. An external circulation-type hollow fiber membrane module is provided with: a hollow fiber membrane bundle; a case; and a short-path prevention body that blocks flowing of a to-be-treated liquid in a gap between the hollow fiber membrane bundle and the case, wherein a first end of the hollow fiber membrane bundle is fixed in the case, and the short-path prevention body is provided to the downstream side of a first port which is a liquid flow-in port in the case so as to project from the inner surface of the case.Type: GrantFiled: December 12, 2019Date of Patent: July 18, 2023Assignee: MITSUBISHI CHEMICAL CLEANSUI CORPORATIONInventors: Yoshie Tanizaki, Hiroyuki Okazaki
