危险废物焚烧工程烟气治理工艺研究
|
摘要
根据回转窑焚烧危险废物后烟气成分的特点,提出采用余热锅炉、旋转喷雾干燥塔、活性炭喷射器、袋式除尘、湿式洗涤塔、SNCR-SCR联合脱硝,上述六种设备组合成烟气治理系统。脱硫脱硝、除尘同时还能有效抑制二英生成,使排放烟气中污染物浓度满足《危险废物焚烧污染控制标准》的限值。
According to the characteristics of the flue gas from hazardous waste rotary kiln,the waste heat boilers,rotary spray drying tower,activated carbon injectors,bag filter,wet scrubbers and SNCR-SCR denitration are combined as a flue gas treatment system. It can not only conduct desulfurization,denitrification and dust-removal,but also effectively inhibit the formation of dioxins. The concentration of pollutants in the treated flue gas can meet the limits of"hazardous waste incineration pollution control standards".
