摘要
介绍了有色冶炼行业低浓度二氧化硫烟气的处理工艺,包括烟气脱硫、非稳态转化工艺、WSA工艺、一转一吸加尾吸工艺、常规两转两吸制酸工艺。企业应结合自身的实际情况,根据冶炼系统不同的烟气浓度和烟气量,选择合适的处理工艺。
The treatment process of low - SO_2 metallurgical flue gases is introduced including flue gas desulfurization,SO_2 unstaedy-state conversion,wet sulphuric acid（WSA）process,single contact（conversion） and single absorption with tail gas absorption process,and double-conversion-absorption process.The enterprises should combine with the actual situation and choose the appropriate treatment process based on the different features about the flue gas concentrations and quantity of the smelting system.
