Abstract

Provided is a carbon dioxide removal apparatus capable of reducing heat loss that can be caused when carbon dioxide is desorbed from an adsorbent. The carbon dioxide removal apparatus includes a frame, and an adsorption-desorption part supported by the frame. A clearance is provided between the frame and the adsorption-desorption part, and an air guide having flexibility is provided in the clearance.

Claims (27)

1 . A carbon dioxide removal apparatus comprising:

a frame; and

an adsorption-desorption part supported by the frame, wherein

a clearance is provided between the frame and the adsorption-desorption part, and

an air guide having flexibility is provided adjacent to the clearance, wherein

the air guide is a sheet-like member,

the air guide has a free end that extends toward the adsorption-desorption part,

the free end moves, due to the flow of air, in a direction in which the free end comes into contact with the adsorption-desorption part.

2 . The carbon dioxide removal apparatus according to claim 1 , wherein

the adsorption-desorption part is partially fixed to the frame via a heat insulating holding member.

3 . The carbon dioxide removal apparatus according to claim 1 , wherein

the adsorption-desorption part comprises a heat exchanger,

the heat exchanger includes a refrigerant inlet and a refrigerant outlet,

the frame has a through hole formed therein,

the refrigerant inlet or the refrigerant outlet is disposed in the through hole,

a pipe flange is interposed between an inner wall of the through hole and the refrigerant inlet or the refrigerant outlet, and

a heat insulator is interposed between the pipe flange and the refrigerant inlet or the refrigerant outlet.

4 . The carbon dioxide removal apparatus according to claim 3 , wherein

a heat insulator is disposed in at least part of a portion between the frame and the pipe flange.

5 . The carbon dioxide removal apparatus according to claim 3 , wherein

a gap is provided between the frame and the pipe flange in the through hole,

the pipe flange has a mounting hole via which the pipe flange is fixed to the frame, and

the mounting hole includes an opening having an elongated circular shape.

6 . The carbon dioxide removal apparatus according to claim 1 , wherein

in a state in which an inside of the frame is decompressed, a degree of contact increases between the air guide and the adsorption-desorption part.

7 . The carbon dioxide removal apparatus according to claim 1 , wherein

the air guide is a foam material.
