Sintering flue gas desulfurization and denitrification method and device

Abstract

The invention discloses a sintering flue gas desulfurization and denitrification method and device, and belongs to the technical field of desulfurization and denitrification. The sintering flue gas desulfurization and denitrification device comprises a cylinder body, a cylinder cover arranged above the cylinder body in a sealing manner, and a conveyor mounted on the right side surface of the cylinder body. The conveyor is assembled to be used for conveying active coke adsorption particles in the cylinder body, so that the active coke adsorption particles can fall down from top to bottom, be conveyed to the upper part and fall down again. An H-shaped support is arranged and matched with a spiral feeding rod and an obliquely-arranged permeable plate for use, a filter screen on the H-shaped support is used for dedusting flue gas, an activated carbon adsorption net is used for primary desulfurization and denitrification, the active coke adsorption particles in the cylinder body fall down from top to bottom and are sprayed out from bottom to top together with flue gas, secondary desulfurization and denitrification are achieved, and the desulfurization and denitrification effects are good. Meanwhile, the spiral feeding rod is arranged and matched with the permeable plate, so that the active coke adsorption particles can be recycled, and the desulfurization and denitrification working efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of desulfurization and denitrification, and in particular relates to a desulfurization and denitrification method for sintering flue gas and a device thereof. Background technique [0002] Sintering, which refers to transforming powdery materials into dense bodies, is a traditional process. People have long used this process to produce ceramics, powder metallurgy, refractory materials, ultra-high temperature materials, etc. Generally speaking, the dense body obtained by sintering after the powder is formed is a polycrystalline material, and its microstructure is composed of crystals, glass bodies and pores. The sintering process directly affects the grain size, pore size, and grain boundary shape and distribution in the microstructure, which in turn affects the performance of the material. The flue gas generated during the sintering process will be doped with sulfur and nitrate components, so desulfurizatio...
