요약

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.

A dry carbon dioxide (CO2) capturing (100) device which includes at least two, i.e. a first and second dry carbon dioxide (CO2) capturing parts comprising: a first and second recovery reactors (104, 105) to recover CO2 by contacting a solid sorbent with exhaust gas, which is fed from outside through an exhaust gas supply line and contains CO2;a first and second recovery cyclones (106, 122) connected to the recovery reactors to discharge a gas while separating the solid sorbent capturing CO2 ('CO2-captured solid sorbent') only;a first and second regenerators (110, 126) connected to the recovery cyclones (106, 122) to receive the CO2-captured solid sorbent and separate CO2 captured in the solid sorbent through a fluidized gas; anda first and second pre-treatment reactors (116, 132) connected to the regenerators through sorbent supply lines to cool the solid sorbent free from CO2 and feedback the cooled solid sorbent to the recovery reactors,wherein 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, anddifferent solid sorbents are used in the first and second CO2 capturing parts, andwherein the solid sorbent used in the first dry CO2 capturing part has a lower sorption temperature range for absorbing CO2 than the solid sorbent used in the second dry CO2 capturing part.
