Treatment device for desulfurization and denitration of high-temperature industrial flue gas

Abstract

The invention relates to a treatment device for desulfurization and denitration of high-temperature industrial flue gas. The device comprises a smoke inlet pipe, a connecting flange and a smoke removing device body, wherein the smoke inlet pipe is of an inverted L-shaped structure, the smoke inlet pipe is of a hollow circular pipe structure, and the connecting flange is fixedly mounted at the endpart of the smoke inlet pipe; and the smoke removing device body is installed inside the smoke inlet pipe. Through the treatment device, the following problems are solved that when existing equipmentis applied to treatment of flue gas, a poor filtering effect and a short treatment time are obtained, filtration and impurity removal cannot be performed on the flue gas effectively, and harmful substances exist in the discharged flue gas; and when desulfurization and denitration treatment is performed on the flue gas, a reaction is performed through only contact of the flue gas with one side surface of a smoke removal pad, the other side surface of the smoke removal pad has a poor reaction effect with the flue gas, one side of the smoke removal pad is blocked easily after a long time of use,and the effect of flue gas treatment is affected.

Description

technical field [0001] The invention relates to the field of industrial flue gas treatment, in particular to a high-temperature industrial flue gas desulfurization and denitration treatment device. Background technique [0002] Industrial flue gas refers to the general term for all kinds of pollutant gases discharged into the air generated during fuel combustion and production processes in the factory area. Flue gas treatment is to effectively treat the toxic and harmful substances contained in the flue gas to a specified concentration. Under, and should avoid equipment corrosion or blockage and other adverse phenomena. With the continuous development of industry, a large amount of industrial flue gas is discharged into the air, causing serious pollution to the atmospheric environment and causing harm to human bodies. Before the flue gas is discharged, the flue gas needs to be treated in a harmless manner. [0003] At present, when the existing equipment desulfurizes and de...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment has poor filtering effect and short processing time when processing the flue gas, cannot effectively filter and remove impurities from the flue gas, and there are many harmful substances in the discharged flue gas, and During the desulfurization and denitrification reaction treatment of flue gas, the flue gas can usually only contact and react with one side of the smoke removal pad, and the other side of the smoke removal pad has a poor reaction with the flue gas. Blockage, affecting the effect of flue gas treatment and other problems
