氨吸收法处理低浓度SO_2烟气在铅锑冶炼上的应用

Application of Ammonia Absorbed Method to Dispose Low Concentration SO_2 Exhaust in Process of Lead and Tin Metallurgy

针对铅锑冶炼厂环保车间石灰乳喷淋处理低浓度SO2烟气存在的问题,对环保车间进行了技术改造,采用碳酸氢氨水溶液代替石灰乳喷淋处理低浓度SO2烟气,副产亚硫酸氨产品,取得了良好的效果。

As the problem in low concentration SO2 exhaust disposal processes through spraying milk of lime in environment protection plant of Lead and Tin metallurgy factory, the technology reform has been done. Ammonia Bicarbonate displaced the milk of lime to dispose low concentration SO2 exhaust, the byproduct was Ammonia Sulrite, and good effect were gotten.
