| 摘 要： | 为了研究适应我国国情的低浓度ＳＯ２冶炼烟气修复方法，在某铜冶炼厂通过试验考察了Ｍｎ＾２＋，Ｆｅ＾２＋，Ｚｎ＾２＋３种金属离子吸收液对ＳＯ２烟气的净化性能，并由正交试验找出了混合吸收液的最优配比。采用混合吸收液净化处理低浓度ＳＯ２冶炼烟气，当吸收液中硫酸浓度为２０％时，泡沫吸收塔的ＳＯ２净化效率仍可保持在８５％以上。

| Abstract: | In order to approach an applicable method of purifying smelting-gases containing so,in low concentration for China,the experimental research of catalytic oxidizing SO2 in smelting-gas by Mn2+,Fe2+ and Zn2+ in liquid-phase was performed in a copper smelter.The optimum proportion of metal ions in the absorption solution was obtained by the orthogonal experiment.The solution with mixed metal ions offered a better purification ability to smelting-gases,when the concentration of H2SO4 in the solution rose to 20%,the purification efficiency of SO2 still could be maintained above 85%.The method is aPPlicable for the waste gas treatment in the smelter of nonferrous metals. |
