Activated carbon static sorting device

Abstract

The invention discloses an activated carbon static sorting device which comprises a vertical sorting cylinder and multiple material guiding chutes. The top of the vertical sorting cylinder is provided with a feed port; the bottom of the vertical sorting cylinder is provided with a discharge port; one side of the lower end of the vertical sorting cylinder is provided with an air inlet; one side of the upper end of the vertical sorting cylinder is provided with an air outlet; the multiple material guiding chutes are located in the vertical sorting cylinder and arranged in the vertical direction; one end of each material guiding chute is fixedly connected with the inner wall of the vertical sorting cylinder; the other end of each material guiding chute inclines downwards; and the fixed ends of any two adjacent material guiding chutes are located on the two sides of the axis of the vertical sorting cylinder respectively. According to the activated carbon static sorting device provided by the invention, activated carbon entering the sorting cylinder slides down along the material guiding chutes which are arranged in an up-and-down staggered mode, meanwhile, dust and fine particles are blown out through reverse air, the falling distance of the activated carbon can be shortened, secondary fragmentation is avoided, coalescent activated carbon can be scattered, and the distance between the particles can be increased, so that the dust and the fine particles in the activated carbon can be effectively removed, and normal operation of a flue gas desulfurization and denitrification adsorption tower is guaranteed.

Description

technical field [0001] The invention relates to a device capable of separating dust and fine particles from activated carbon particles, and belongs to the technical field of separation. Background technique [0002] In the adsorption tower of the activated carbon desulfurization and denitrification device, the activated carbon flows in from the top of the adsorption tower (about 50 meters high), and the flue gas enters from the bottom of the adsorption tower. , to reduce system resistance. The diameter of the initial activated carbon particles is 8-9mm. With the increase of the process running time, the activated carbon will undergo wear and chemical consumption, and the particle size will become smaller and smaller. Small particles and dust filling the gaps in the activated carbon bed will increase the flue gas resistance. , if the distribution is uneven, segregation will be formed to cause unstable air flow, which will increase the instability of the system and reduce the...

Problems solved by technology

The diameter of the initial activated carbon particles is 8-9mm. With the increase of the process running time, the activated carbon will undergo wear and chemical consumption, and the particle size will become smaller and smaller. Small particles and dust filling the gaps in the activated carbon bed will increase the flue gas resistance. , if the distribution is uneven, segregation will be formed to cause unstable air flow, which will increase the instability of the system and reduce the adsorption effect

Moreover, activated carbon dust is easy to accumulate in the adsorption tower, and the accumulated heat will cause local temperature rise and form hot spots, which seriously threaten the safety of the process system

The usual method to solve the above problems is to install a high-efficiency balanced vibrating screen in the activated carbon conveying system, and use the vibrating screen to screen out small particles of activated carbon. Difficult to remove
