Claim:
1. A carbon dioxide capture apparatus having a temperature swing adsorption mode for selective separation of carbon dioxide from flue gases which contain carbon dioxides, comprising: a carbon dioxide sorption column including a carbon dioxide adsorption unit in which adsorption of carbon dioxide from flue gases occurs; a carbon dioxide desorption column connected to the carbon dioxide sorption column and including a carbon dioxide desorption unit in which desorption of the adsorbed carbon dioxide occurs; a carbon dioxide absorbent repeatedly adsorbing and desorbing carbon dioxide while circulating through the carbon dioxide sorption column and the carbon dioxide desorption column; and a heat exchange unit in which heat exchange occurs between the absorbent after carbon dioxide adsorption and the absorbent after carbon dioxide desorption, wherein the heat exchange unit has a structure: in which tubes through which the absorbent after carbon dioxide desorption is moved are inserted into a tube through which the absorbent after carbon dioxide adsorption is moved or tubes through which the absorbent after carbon dioxide adsorption is moved are inserted into a tube through which the absorbent after carbon dioxide desorption is moved; or in which planar passages through which the absorbent after carbon dioxide adsorption is moved are in face-to-face contact with planar passages through which the absorbent after carbon dioxide desorption is moved.
