Dry carbon dioxide capturing device using multi sorbents
Disclosed is a dry CO2 capturing device using multi sorbents so as to maintain the sorption rate for exhaust gas containing CO2. The dry carbon dioxide (CO2) capturing device comprises at least two dry carbon dioxide (CO2) capturing parts comprising: a first and second recovery reactors 104 and 105 to recover CO2 by contacting a solid sorbent with exhaust gas; a first and second recovery cyclones 106 and 122 connected to the recovery reactors; a first and second regenerators 110 and 126 connected to the recovery cyclones; and a first and second pre-treatment reactors 116 and 132 connected to the regenerators through sorbent supply lines. The first and second dry carbon dioxide (CO2) capturing parts are connected to each other so as to feed an isolated gas, which is separated with the solid sorbent in the first recovery cyclone 106 of the first dry CO2 capturing part, to the second dry CO2 capturing part through the exhaust gas supply line, and different solid sorbents are used in the first and second CO2 capturing parts.
