摘要
采用除尘脱硫塔对烟气进行脱硫除尘，吸收用碱液pH控制在8～9，此时S02去除率为90％以上，处理后烟气可以达到《锅炉大气污染物排放标准》GB13271-2001中的Ⅱ时段二类区排放标准。该工艺适合小型烟气处理，能有效地控制二氧化硫烟气对大气的污染。
Desulphurization and dust removal tower is adopted for gas desulphurization and dust removal, pH value of lye for absorption is controlled in 8～9, removal rate of S02 is more than 90%, the gas after being treated can reach emission standard of II time interval Class-2 area in Emission Standard of A ir Pollutants for Boilers （GB13271-2001）, the process is suitable for small-sized gas treatment and can effectively control air pollution issues.
