Carbon dioxide removal apparatus
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.
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.
