电石渣在湿法脱硫中的消溶特性

采用盐酸模拟烟气中的SO2，在釜式反应器中研究了溶液pH值和温度对湿法烟气脱硫中电石渣的消溶特性的影响。实验结果表明：溶液pH值越小，电石渣的消溶速率越快，且在实验控制条件下所达到的最终消溶率也越大；消溶速率随着温度的升高而加快。实验测出了不同工况下电石渣的最终消溶率，并得出了电石渣消溶特性的经验公式。

Dissolution Characteristics of Carbide Slag During Wet Flue Gas Desulfurization

The effect of the solution's pH value and temperature on carbide slag's dissolution property in wet flue gas desulfurization processes has been studied by using a pot type reactor with hydrochloric acid simulating SO2 in flue gas. Test results indicate: the smaller the solution's pH value,the quicker dissolution of carbide proceeds and the larger the final rate of dissolution attained under test conditions;dissolution quickens with rising temperature.The final dissolution rate of carbide was obtained by test measurements and an empirical formula,which reflects the dissolution property of carbide,was found.Figs 4,tables 3 and refs 7.
