摘　　要：综合利用“石灰石-石膏法”和“石灰-石膏法”烟气脱硫的原理,用高锰酸钾生产中产生的苛化渣对锅炉烟气进行脱硫。通过研究反应温度、液固比、干渣粒度以及反应时间对脱硫效果的影响,实验表明在常温、液固比4 mL/g、干渣粒度(+120目^-80目,70%,平均约148μm)、反应时间为7 h脱硫效果较好,最终实现废气、废渣同时治理,既经济又环保。Comprehensive utilization of the principle that"limestone-gypsum process"and"lime-gypsum process"for flue-gas desulfurization,in which the causticizing slag generated from potassium permanganate production can be used for flue-gas desulfurization.The reaction temperature,liquid-solid ratio,the particle size of dry residue,and the effect of reaction time on desulfuration results are studied,the experiment show,the desulfuration effect is better under the following conditions:at normal temperature,the liquid-solid ratio is 4 mL/g,the particle size of dry residue is+120 mesh^-80 mesh,70%,the average particle size is about 148μm,the reaction time is 7 hours.Therefore,it is realized the simultaneous treatment of waste gas and slag,which is economical and environment-friendly.
