摘要:
Disclosed is a CO2 capturing device for improving CO2 removal efficiency and use of a dry solid absorbent. The device comprises a CO2 recovery reactor 1 to permit CO2 containing gas externally supplied to be in contact with a dry solid absorbent to capture CO2; a recovery cyclone 4 connected to the recovery reactor 1 to exhaust CO2-free gas while separating a solid portion containing CO2; a fluidized bed type regeneration reactor 2 which receives the solid portion through a solid feeding pipe 5 connected to the recovery cyclone 4 and divides the solid portion into CO2 and the other part containing the dry solid absorbent by using a fluidizing gas fed through a fluidizing gas supply pipe 8; a regeneration cyclone 6 to exhaust the separated CO2 outside in order to use CO2 in the regeneration reactor 2; and a water vapor pretreatment device 3 connected to the regeneration reactor 2 to absorb H2O in the dry solid absorbent and feedback the H2O containing absorbent to the recovery reactor.
