[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during the combustion of fuel and production processes in the factory area of ​​an enterprise. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead and mercury sulfate, beryllium, smoke and productive dust. When discharged into the atmosphere, they will pollute the air. Desulfurization is the removal of sulfides in the waste gas, and denitrification is the removal of nitrogen oxides NOX in the waste gas. Desulfurization, denitrification and dust removal equipment are needed to treat industrial waste gas, so as to achieve pollution-free treatment of industrial waste gas.

[0003] Among the related technologies, wet flue gas desulfurization produces a large amount of wastewater, increasing the risk of secondary pollution; although dry flue gas desulfurization is easy to operate, its desulfurization efficiency is low and it cannot meet strict emission standards; selective catalytic reduction (SCR) denitrification relies on expensive catalysts and needs to be replaced regularly, resulting in high operating costs; although electrostatic precipitator can effectively capture most particulate matter, its capture effect on fine particles is poor, making it difficult to fully meet the standards.
