阐述了铜冶炼提铜尾渣作为冶炼烟气脱硫剂的反应机理,并进一步阐述pH、烟气流速、矿浆浓度对烟气脱硫的影响。试验表明,提铜尾渣具有很强的脱除SO2的能力,最佳试验参数为pH=1、固液比1∶3、烟气流速在400mL/min以下,脱硫效率可提高至95%左右。
Abstract：Reaction mechanism of copper extraction tailings as desulfurizer for smelting flue gas was studied.Influence of pH value,flue gas flow rate and slurry concentration on flue gas desulfurization was investigated.The experimental results show that copper tailings have strong ability to remove SO2.Desulfurization efficiency can be improved to be about 95% under the optimum conditions including pH value of 1,ratio of solid to liquid of 1∶3,and flue gas flow rate of 400 mL/min below.
