PROBLEM TO BE SOLVED: To provide a humidification device capable of reducing pressure drop and suppressing variation of humidification efficiency or tuning performance of pressure drop.SOLUTION: A humidification device is formed by a housing storing a hollow yarn membrane module case. Between an inner peripheral face of the housing for storing the case and a case wall face, through holes are formed on convex rib parts extended in a belt shape at two points from the case wall face with respect to a case longitudinal axial direction. Longitudinal axial direction side face ends of the convex ribs contact, preferably contact in a fitted state, to a projection part or a recessed part provided on the inner peripheral face of the housing.

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane cartridge in which airtightness is inspected and decrease in airtightness due to adhesion of active carbon is prevented. SOLUTION: The active carbon 50 is filled into an annular gap between a hollow fiber membrane module 40 and a first case 20. Thereafter, a plug 60 integrally formed with a meshed member 61 which is more finely meshed than the active carbon 50 is mounted in an introduction hole 32 of a second case 30. COPYRIGHT: (C)2004,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a hollow fiber membrane module in which both bundle end parts of hollow fiber membranes are inserted each into a bundle binding tube and fixed to each bundle binding tube through a potting part so that only the hollow inside of the hollow fiber membrane is opened to the outside and which enables not only hollow fiber membranes positioned in the peripheral surface on the side of the bundle of hollow fiber membranes or in the vicinity of the peripheral surface but hollow fiber membranes positioned inside the bundle of hollow fiber membranes to function effectively.SOLUTION: In a hollow fiber membrane module in which both bundle end parts of hollow fiber membranes are inserted each into a bundle binding tube and fixed to each bundle binding tube through a potting part so that only the hollow inside of the hollow fiber membrane is opened to the outside, hollow opening parts of the hollow fiber membranes in one end part of a hollow fiber membrane bundle are sealed with a sealing material, and, in the central part of the potting part in the module end part on the side where the hollow inside of hollow fiber membranes are sealed, there is provided a through hole penetrating the inside of the module and serving as an outlet for a fluid supplied externally to the module.
