Dust removal and desulfurizing system for treating industrial waste gas by using viscous absorption liquid and treatment method

Abstract

The invention discloses a dust removal and desulfurizing system for treating industrial waste gas by using viscous absorption liquid and a treatment method. The dust removal and desulfurizing system comprises a dust removal and desulfurizing container, a viscous absorption liquid circulating tower, an industrial waste gas source and a gas receiving tower, the viscous absorption liquid circulatingtower circularly supplies the viscous absorption liquid to the dust removal and desulfurizing container, the industrial waste gas source conveys industrial waste gas to the dust removal and desulfurizing container, and the industrial waste gas subjected to dust removal and desulfurizing is received by the gas receiving tower; the dust removal and desulfurizing container is provided with a cylindrical dust removal and desulfurizing cavity and an annular liquid distribution cavity from inside to outside, the cylindrical dust removal and desulfurizing cavity is inserted into a vertical pipe, thevertical pipe is provided with a gas distribution stirring assembly and an elastic spiral choked flow blade assembly from top to bottom, and viscous absorption liquid is stirred while the gas distribution stirring assembly distributes gas; and the elastic spiral choked flow blade assembly conveys the viscous absorption liquid downwards to chock flow of industrial waste gas and generates vertical elastic vibration under flow impact of the viscous absorption liquid at the same time. The dust removal and desulfurizing system integrates industrial waste gas dedusting and desulfurizing, and dedusting and desulfurizing are thorough and efficient.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a dust removal and desulfurization system and a treatment method for treating industrial waste gas with viscous absorption liquid. Background technique [0002] In the existing industrial waste gas treatment process, the two indispensable processes are dust removal and desulfurization. Since the two processes of dust removal and desulfurization are carried out separately, the efficiency of waste gas treatment is low. In addition, dust removal is usually carried out by cyclone separator or directly into clean water. , has the defects of incomplete dust removal and too fast diversion of exhaust gas. Desulfurization is mostly absorbed by alkaline absorption liquid. The mixing and contact of the two is not thorough enough, resulting in excessive sulfur dioxide residues that do not meet the standard. Recycling desulfurization treatment is required, and the effic...
