影响固定床烟气脱硫因素的实验研究
The Experimental Study of the Factors that Affecting the Removal Efficiency of SO2 in Fixed-bed
【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。
【Abstract】 CaO was chosen to be absorbent in the drying fixed-bed which was used to desulfur in the experiment. The effect regulation oftemperature、 inlet concentration of SO2、Ca/S molar ratio、diameter of the absorbent and resident time on desulphurization efficiency werestudied. The results show that when =825 ℃、Ca/S=2.82、 =75 m、 in=1 783 mg/m3、 R=0.4 s, =89.6%, and the outletconcentration of SO2, out=185 mg/m3, is less than 260 mg/m3 which is national standard.
