Abstract: An apparatus for drying particles in a fluidized state includes a particle input segment into which wet particles are input, a drying segment having a multi-perforated plate dividing an inner space of the drying segment into an upper section and a lower section, a plurality of upper partition plates partitioning the upper section and positioned above the multi-perforated plate, a plurality of lower partition plates in the lower section respectively corresponding to the plurality of upper partition plates, a plurality of pairs of channel plates in the lower section that pass through the multi-perforated plate such that each pair of the plurality of pairs of channel plates are respectively arranged on opposite sides of respective ones of the plurality of upper partition plates and on opposite sides of respective ones of the plurality of lower partition plates; and a heated-air flow supply segment for supplying hot gas to the drying segment.

Abstract: 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.

Abstract: 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.
