High-temperature desulfurization technologies, such as wet desulfurization and dry desulfurization, are used to remove sulfides from flue gas. Among them, wet desulfurization mostly uses equipment such as spray absorption towers or absorption columns to contact flue gas with desulfurization liquid to cause a chemical reaction and convert sulfides into harmless substances; dry desulfurization is achieved by adding dry desulfurization agents, such as activated carbon, lime, calcium silicate, etc., to high-temperature flue gas to adsorb or chemically react sulfides to achieve removal effects.
