摘　　要：针对多膛炉焙烧氧化锌烟尘氟氯脱除率低的问题,开展氧化锌烟尘焙烧过程热力学分析,基于热力学分析结果进行试验验证。研究结果表明:在烟气流量400 mL/min,烟气成分为SO_(2)0.32%、O_(2)7.61%、H_(2)O 9.61%、N_(2)82.46%(烟气成分为模拟回转窑烟气),焙烧温度700℃,焙烧时间210 min的较优条件下,氟氯的脱除率分别为98.06%、91.56%。To address low removal rate of fluorine and chlorine from zinc oxide flue dust roasted in multi hearth furnace,thermodynamic analysis of zinc oxide flue dust roasting process was carried out,and experimental verification was carried out based on thermodynamic analysis results.The results show that removal rates of fluorine and chlorine is 98.06% and 91.56% respectively under the condition including flue gas flow of 400 mL/min,flue gas components of SO_(2)0.32%,O_(2)7.61%,H;O 9.61%,N_(2)82.46%(simulation of flue gas of rotary kiln),roasting temperature of 700℃,and roasting time of 210 min.
