Disclosed is a dry carbon dioxide capture apparatus with improved carbon dioxide capture efficiency through preventing gas backflows into vertical transport lines. The dry CO2 capture apparatus includes a capture reactor having a capture buffer chamber on the bottom side, a capture diffusion plate on top of the capture buffer chamber, and adsorbent particles in a space above the capture diffusion plate; a first separator connected to the capture reactor through a vertical transport line; a regenerator having a regeneration buffer chamber on the bottom side, a regenerating diffusion plate on top of the regeneration buffer chamber, and adsorbent particles in a space above the regenerating diffusion plate; a second separator connected to the regenerator through a gas separation line; and a second particle transfer line connected to the regenerator at one end and connected to the capture reactor at the other end.

Dry carbon dioxide capture 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 reactorto permit CO containing gas externally supplied to be in contact with a dry solid absorbent to capture CO; a recovery cycloneconnected to the recovery reactorto exhaust CO-free gas while separating a solid portion containing CO; a fluidized bed type regeneration reactorwhich receives the solid portion through a solid feeding pipeconnected to the recovery cycloneand 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; a regeneration cycloneto exhaust the separated CO outside in order to use CO in the regeneration reactor; and a water vapor pretreatment deviceconnected to the regeneration reactorto absorb H O in the dry solid absorbent and feedback the H O containing absorbent to the recovery reactor
