Abstract

The invention discloses an activated carbon desulfurization and denitrification regeneration system, and belongs to the technical field of flue gas purification. The system comprises a horizontal tower body and a conveying device, wherein the horizontal tower body comprises a heating insulation chamber and a cooling chamber; a protective gas inlet and a feeding hole are formed in the heating insulation chamber; a protective gas outlet and a discharging hole are formed in the cooling chamber; the conveying device is arranged in the horizontal tower body and comprises a conveying mechanism and ahopper; and the conveying mechanism is configured to convey activated carbon entering the hopper from the feeding hole to the discharging hole. According to the activated carbon desulfurization and denitrification regeneration system, by arranging the horizontal tower body and the hopper, compared with the prior art, the extrusion of the activated carbon at the bottom of a tower can be reduced, and the activated carbon is not directly in frictional collision with the tower wall of the horizontal tower body, so that the physical loss of the activated carbon can be reduced. In addition, by arranging the horizontal tower body, the distance between the bottom of the adsorption tower and the feeding hole can be reduced, so that the energy consumption for conveying the activated carbon from thebottom of the adsorption tower to the feeding hole can be reduced, the efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to an activated carbon desulfurization and denitrification regeneration system. Background technique [0002] As a collaborative purification technology for industrial flue gas pollutants, activated carbon desulfurization and denitrification can not only achieve joint removal of SO 2 , NO x It has the function of dust and dust, and has the advantages of high removal efficiency, small footprint, low investment and operating costs. Active desulfurization and denitrification technology mainly uses activated carbon to treat SO in the flue gas. 2 , NO x , dust and other components adsorption and catalytic oxidation, catalytic reduction removal. The whole system mainly includes desulfurization and denitrification reactor, regeneration reactor and SO 2 Gas recovery processing unit. When the flue gas passes through the activated carbon bed of the adsorption desulfurizati...
