摘要
通过新增选择性非催化还原脱硝装置(SNCR)和湿法烟气脱硫装置,以及对原有的急冷塔和布袋除尘器进行改造,使焚烧装置外排烟气满足相关环保要求,即SO_(2)质量浓度≤50 mg/m^(3)、NO_(x)质量浓度≤250 mg/m^(3)、烟尘质量浓度≤20 mg/m^(3),改造经验值可供类似项目参考。
The selective non catalytic reduction(SNCR)and FGD system are selected,and the original quench tower and bag filter are upgraded,which can make the flue gas discharged from the incineration device meet the local environmental requirements,that is,SO_(2) concentration≤50 mg/m^(3),NO_(x) concentration≤250 mg/m^(3) and dust concentration≤20 mg/m^(3).The experience can be used as reference for similar projects.
