Abstract

The invention relates to a treating agent for removing sulfur dioxide, sulfur trioxide and hydrogen sulfide from tail gas of an oil burning boiler. The treating agent is prepared by compounding following components: 2-ethoxy benzaldehyde, 4-methoxy benzyl bromide, cyclohexanone, N,N-diethylethanamine, 3-butene-1-alcohol, 1-tetralone, tricresyl phosphate, N,N-dimethyl trimethylene diamine, 2-methoxy-5-fluorouracil, isopropamide, N-butyloxycarboryl-3-piperidone, ethyl chlorooxoacetate, N,N-dimethyl methylamine, 2-bromine-4'-methylacetophenone, quinoline-2-formaldehyde, absolute ethyl alcohol, and the like. The treating agent is strong in complexing power with target matters, the speed of forming complex and sediment is high, the removal rate can reach 99%, the cost is low, the dosage is less, no scaling is formed and no damage is caused to the environment.

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...
