<P>PROBLEM TO BE SOLVED: To provide a dry carbon dioxide capture apparatus with improved carbon dioxide capture efficiency through preventing gas backflows into a vertical transport pipe by using a bubble fluidized bed capture device. <P>SOLUTION: The dry carbon dioxide capture apparatus includes a capture reactor 101 having a capture buffer chamber 102 communicated with a gas inflow pipe 106 on the bottom side, a capture diffusion plate 104 covering the top of the capture buffer chamber, and absorbent particles 138 stored in a space above the capture diffusion plate; the vertical transport pipe 108 having one end connected to the capture reactor and the other end connected to a first separator 112 for capturing carbon dioxide by the absorbent particles and separating and delivering the remaining gas; a regeneration reactor 124 communicated with a regeneration heat source inflow pipe in the lower part and to which the absorbent particles separated by the first separator are supplied by a first particle transfer pipe connected to the first separator; a second separator 120 for separating and delivering only carbon dioxide separated by the regeneration reactor; and a second particle transfer pipe 132 connected to the regeneration reactor at one end and connected to the capture reactor at the other end. <P>COPYRIGHT: (C)2012,JPO&INPIT |
