Description

Technical Field

[0001] The invention relates to the technical field of flue gas treatment, and in particular to a high-efficiency flue gas desulfurization and environmentally friendly device. Background Art

[0002] Flue gas desulfurization is widely used in many industries that generate large amounts of sulfur oxide emissions, including but not limited to: Power industry: Coal-fired power plants are the main application area for flue gas desulfurization equipment, because the flue gas generated by coal burning contains a large amount of sulfur dioxide. Iron and steel metallurgical industry: Flue gas generated in the process of iron and steel making, including blast furnaces, converters, coke ovens, etc., also needs to be desulfurized. Chemical industry: Waste gas generated in processes such as coal chemical industry, petrochemical industry, fertilizer, and sulfuric acid production often needs to be desulfurized. Building materials industry: Cement plants, glass plants, etc. also release sulfur-containing flue gas during the production process, which requires flue gas desulfurization equipment for treatment. Non-ferrous metal smelting: Flue gas generated in the smelting process of metals such as lead, zinc, and copper also needs to be desulfurized.

[0003] At present, a single method is often used for flue gas desulfurization. This method does not fully absorb the sulfur-containing gas in the flue gas, which easily causes the leakage of sulfur-containing gas and damages the environment. In order to better solve this problem, we propose an efficient flue gas desulfurization environmentally friendly device. Summary of the invention
