摘　　要：以CaO粉末做吸收剂,通过固定床干法脱硫实验,分别研究了温度、进口浓度、Ca/S摩尔比、吸收剂粒径和停留时间等各因素对脱硫效率的影响,结果表明:当=825℃、Ca/S=2.82、粒径为75m、进口浓度in=1783mg/m3、R=0.4s时,脱硫效率可达89.6%,出口SO2浓度为185mg/m3,低于国家标准规定的260mg/m3。CaO was chosen to be absorbent in the drying fixed-bed which was used to desulfur in the experiment, The effect regulation of temperature, inlet concentration of SO2, Ca/S molar ratio, diameter of the absorbent and resident time on desulphurization efficiency were studied. The results show that when T= 825 ℃, Ca/S= 2,82, d= 75μm, Ci= 1783 mg/m^3, tR= 0.4 s, η = 89.6%, and the outlet concentration of SO2, Cout = 185 mg/m^3, is less than 260 mg/m^3 which is national standard.
