Abstract:
1. A dry carbon dioxide (CO 2 ) capture apparatus, comprising: a capture reactor wherein a capture buffer chamber connected with a gas inflow line is provided on the bottom side of the capture reactor, a capture diffusion plate is provided on a top side of the capture buffer chamber, and adsorbent particles are charged in a part of a space which is formed above the capture diffusion plate; a first separator connected to the capture reactor through a vertical transport line, in order to separate the adsorbent particles fed from the capture reactor into a solid part and a gas residue remaining after removing CO 2 by the adsorbent particles, then, discharge the gas residue; a regenerator wherein a regeneration buffer chamber connected to a regenerated heat source input line is provided on the bottom side of the regenerator, and a regenerating diffusion plate is provided on the top side of the regeneration buffer chamber, and adsorbent particles are charged in a part of a space which is formed above the regenerating diffusion plate, and wherein the regenerator is connected to the first separator through a first particle transfer line and receives solid adsorbent particles therefrom; a second separator connected to the regenerator through a gas separation line, in order to separate CO 2 only from the adsorbent particles in a powder state fed from the regenerator, then, discharge the separated CO 2 ; and a second particle transfer line connected to the regenerator at one end and connected to the capture reactor at the other end, wherein the bottom end of the vertical transport line is located lower than a height of the adsorbent particles charged in the capture reactor.
