| 中文摘要 |
| 为了研究适应我国国情的低浓度SO2冶炼烟气净化处理方法,在某铜冶炼厂通过试验考察了Mn2+、Fe2+、Zn2+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。这一方法对于中小型有色冶金企业的低浓度SO2冶炼烟气以及冶炼烟气制酸尾气的净化处理具有很好的适用性。 |
| 英文摘要 |
| 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. |
