摘　　要：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。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.
