Abstract

The invention relates to a treatment agent for removing sulfide from oil-fired boiler tail gas. The treatment agent is prepared by compounding of the following components: 5, 7-trihydroxy-2- (3, 4, 5-trihydroxyphenyl)-4H-1-benzofuran-4-one, harringtonine, 7-hydroxy-6-methoxy-2H-1-benzopyran-2-one, pentahydroxyflavone-3-rhamnoside, 3-methyl pyridazine, 4-acetoxy-3-methoxy-(2-allyl)benzene, 4, 4'-sulfonyldianiline, and 3-methyl-3-phenyloxiranecarboxylic acid ethyl ester, 5-allyl-2, 3-(methylenedioxy)anisole, etc. The treatment agent has strong complexing ability with a target material, the complex precipitate forming rate is fast, the removal rate can reach 99%, the cost is low, the dosage is small, scaling does not form, and the treatment agent does not cause environmental harm.

Description

technical field [0001] The invention relates to a treatment agent for removing sulfur dioxide, sulfur trioxide and hydrogen sulfide in the tail gas of an oil-fired boiler, and belongs to the technical field of environmental protection. Background technique [0002] Desulfurizers generally refer to agents that remove free sulfur or sulfur compounds in fuels, raw materials or other materials; in the control and treatment of pollutants, they mainly refer to the removal of sulfur compounds (such as SO 2 , SO 3 and H 2 S) Agents used. Several commonly used desulfurizers are: calcium-based desulfurizer, sodium-based desulfurizer, magnesium-based desulfurizer, amino desulfurizer, etc. [0003] Calcium-based desulfurizers are most commonly used in desulfurization. Commonly used calcium-based desulfurizers include lime, slaked lime, carbide slag, limestone, and dolomite, which can also be obtained from calcium-rich industrial waste residues and raw materials. The advantage of thi...
