摘要： An air purifying system includes: a carbon dioxide remover including first and second spaces partitioned by a gas permeable membrane with 50 nm or less diameter micropores; a feed passage leading to-be-purified air from a room to the first space; a supply passage supplying clean gas having lower carbon dioxide and higher oxygen concentrations than the to-be-purified air to the second space; a discharge passage discharging, from the second space, mixed gas; a return passage leading purified air from the first space into the room, the purified air resulting from removing carbon dioxide from the to-be-purified air; and adjusting equipment adjusting a gas pressure in the first and second spaces to be substantially equal to each other. The to-be-purified air flows in the first space along a surface of the gas permeable membrane, and the clean gas flows in the second space along a surface of the gas permeable membrane.

摘要： A gas separation membrane module includes at least one hollow fiber membrane element and a casing. The hollow fiber membrane element includes hollow fiber membranes and a cylindrical body. The cylindrical body extends in a longitudinal direction of the hollow fiber membranes, and accommodates the hollow fiber membranes. The hollow fiber membrane element includes sweep gas introduction ports and mixed gas discharge ports. A first supply chamber, a first discharge chamber, a second supply chamber, and a second discharge chamber are positioned between the casing and the hollow fiber membrane element. The first supply chamber, the first discharge chamber, the second supply chamber, and the second discharge chamber are partitioned off from each other.

摘要： Each of a pair of couplers includes: a vacuum double-pipe structure main part; a valve seat forming an opening through which a fluid flows; and a valve body in the main part. The valve body is configured such that, when separating the couplers, in each coupler, the body is brought into contact with the seat by a spring to close the opening, and when coupling the couplers, the body of each coupler is pressed by the body of the other coupler to move away from the seat and open the opening. The valve body includes: a holding member holding a sealing material sealing between the body and the seat when the body is in contact with the seat; a resin block covering a distal end surface of the holding member; and a metal operating member accommodating the block and protruding from the holding member to pass through the opening.
