摘要
以镁钙砖烧成用隧道窑烟气治理为例,提出了干法脱硫、选择性催化还原(简称SCR)脱硝的治理工艺。据此,可以实现二氧化硫、粉尘和氮氧化物的排放浓度分别低于10、35和50 mg·m^(-3)的超低排放标准。该工艺已在山西某生产镁钙砖的耐火材料企业投入使用,运行效果良好,但每吨产品增加成本约13.5元。
Taking the flue gas treatment of tunnel kilns for firing magnesia-calcia brick as an example,the treatment process of dry desulphurization and SCR denitrification technology was put forward.The ultra-low emission standards of sulfur dioxide,dust and nitrogen oxide lower than 10,35 and 50 mg·m^(-3),respectively were realized.The process has been put into use in a magnesia-calcia brick enterprise in Shanxi Province,and the operation effect was good,but the cost of per ton product increased about CNY13.5.
