Dry desulfurization and denitrification device for catalytic cracking regenerated flue gas

The utility model belongs to the technical field of flue gas treatment, and discloses a dry desulfurization and denitrification device for catalytic cracking regenerated flue gas, which comprises a shell, a cover plate is fixedly mounted at the top of the shell, a guide barrel is fixedly mounted in the middle of the interior of the shell, and three bearing plates are fixedly mounted in the guide barrel at equal intervals. A base is fixedly mounted at the bottom in the shell, and clamping grooves are formed in the left end and the right end of the upper end in the base correspondingly. By arranging the desulfurization plate, the guide plate, the denitration plates and the like, the purpose of good desulfurization and denitration effects is achieved, flue gas enters the shell and the guide barrel through the communicating pipe, the flue gas passes through the three denitration plates, and the denitrated flue gas enters the outer end of the interior of the shell through the top of the guide barrel; the flue gas
