Problems solved by technology

At present, the dust removal methods mainly include electrostatic dust removal, cloth bag dust removal, electric bag composite dust removal, wet electrostatic dust removal, etc. It is difficult to achieve ultra-low emission standards with a single dust removal method, while the combined dust removal system is complex, high in investment, large in floor area, and easy to operate. The cost is high, it is difficult to improve the dust removal standard of the existing equipment, and the burden on the enterprise is heavy, so it is urgent to study new dust removal technology

Description

technical field [0001] The invention belongs to the technical field of boiler flue gas dedusting, and in particular relates to a labyrinth swirl dedusting device and a dedusting method. Background technique [0002] In recent years, the situation of air pollution control in my country has been severe. Haze weather has occurred from time to time and shows a worsening trend. The main factor causing haze is the high concentration of particulate matter. The main reason is that the concentration of dust emitted by industrial production is too high. At present, my country's heavy air pollution areas are concentrated in Northeast China, North China, and Central China. Industries such as steel, cement, building materials, chemicals, electric power, and papermaking are affected by uneven regional economic development. Most of the environmental protection facilities are relatively old, with low efficiency and excessive renovation costs. High, resulting in serious excessive emissions. ...
