摘　　要：铝电解槽产生的含SO2、CO、HF烟气,目前采用氧化铝干法吸附净化技术,能获得较高的氟净化效率,但不能脱除SO2,部分铝电解槽烟气中SO2浓度超过国家铝电解行业新环保标准中SO2最高允许排放浓度限值。本研究集成低浓度SO2烟气治理技术及硫酸锰生产技术,获得"铝电解槽低浓度二氧化硫烟气循环利用生产硫酸锰的方法"国家发明专利。文章介绍了研究成果,可为低浓度SO2烟气治理提供技术支持。Aluminum oxide-dry adsorption purification technology is adopted for the gas generated from aluminum electrolysis cell containing with SO2 , CO, HF, so that the high fluorine purification efficiency can be got, but the SO： cannot be removed, the SO2 con- centration in the gas in the part of aluminum electrolysis cell exceed the maximum allowable discharge concentration limit specified in the new environmental protection standards of national aluminum electrolytic industry. The low concentration SO2 gas treatment technology and man- ganese sulfate production technology is integrated studied, and the national invention patent Manganese Sulfate Production Process Technolo- gy by Recycling Low Concentration SO2 Gas Generated from Aluminum Electrolysis Cell is obtained. The research results of this technology are introduced, which can supply the technical support to low concentration SO2 gas treatment.
