摘要
本文针对河北省某钢厂烧结机烟气不达标现状,增设SDA喷雾旋转脱硫除尘及SCR选择性催化还原脱硝装置。技改后,烧结烟气中颗粒物浓度降至1.8mg/m^3,二氧化硫浓度降至30mg/m^3,氮氧化物浓度降至45mg/m^3,实现达标排放。
In view of the current situation of sintering machine flue gas non-compliance in a steel plant in Hebei province, SDA spray rotary desulfurization and dedusting and SCR selective catalytic reduction denitration device were set up. After technical transformation, the concentration of particulate matter in sintering flue gas is reduced to 1.8 mg/m3, sulfur dioxide concentration to 30 mg/m3, and nitrogen oxide concentration to 45 mg/m3, achieving the emission standard.
