Carbon dioxide capture and liquefaction device

The invention provides a carbon dioxide capture and liquefaction device. The first end of an absorption tower is connected with a carbon dioxide gas source so that carbon dioxide can react with a lean amine solution in the absorption tower to generate a rich amine solution. The first end of a first...

Beschreibung
Zusammenfassung:	The invention provides a carbon dioxide capture and liquefaction device. The first end of an absorption tower is connected with a carbon dioxide gas source so that carbon dioxide can react with a lean amine solution in the absorption tower to generate a rich amine solution. The first end of a first heat exchanger is connected with an outlet of the absorption tower, the second end of the first heat exchanger is connected with one end of a reboiler, and the first heat exchanger is used for using high-temperature steam condensate in the reboiler for primary heat exchange with the rich amine solution. The first end of a second heat exchanger is connected with the third end of the first heat exchanger, the second end of the second heat exchanger is connected with the first end of a desorption tower, and the second heat exchanger is used for secondary heat exchange with the rich amine solution after primary heat exchange. The second end of the desorption tower is connected with the other end of the reboiler so that
