| 摘 要： | 基于烟气中氧气与二氧化硫浓度之间的关系对软锰矿浆烟气脱硫反应的影响机理分析,提出用氧硫比(氧气与二氧化硫的摩尔比)作为关联烟气含氧量与二氧化硫浓度的参数,考察了烟气氧硫比对软锰矿浆烟气脱硫体系锰浸出率及脱硫产物的影响,据此探讨了提高锰浸出率与硫酸锰产量的方法.结果表明,氧硫比是体系pH值变化的指针因子,并通过改变体系的...

| Abstract: | Based on analyzing the mechanism of the effect of the relationship between the concentration ratio of O2 and SO2 in the flue gas on the desulphurization reaction,the O2/SO2(molar ratio) was put forward as a correlated parameter for the concentrations of O2 and SO2 in the flue gas.The effect of O2/SO2 on the Mn2+ extraction ratio and byproduct formation were investigated,and the measures for increasing Mn2+ extraction ratio and output of MnSO4 were presented.The results show that the O2/SO2 is the decisive f... |
