Carbon dioxide capturing device including water vapor pretreatment apparatus
Disclosed is a CO capturing device for improving CO removal efficiency and use of a dry solid absorbent. The device comprises a CO recovery reactor 1 to permit CO containing gas externally supplied to be in contact with a dry solid absorbent to capture CO; a recovery cyclone 4 connected to the recovery reactor 1 to exhaust CO-free gas while separating a solid portion containing CO; 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 CO 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 CO outside in order to use CO in the regeneration reactor 2; and a water vapor pretreatment device 3 connected to the regeneration reactor 2 to absorb H O in the dry solid absorbent and feedback the H O containing absorbent to the recovery reactor 1.
