机焦炉排放的大气污染物浓度特征研究

Research on Concentration of Atmospheric Pollutants from the Operation Process of Machine-coke Oven

调查焦化厂各排放源排放污染物浓度特征,得出焦炉烟囱排放的颗粒物、SO_2和NO_x浓度分别为48.6 mg/m3、35mg/m^3和165 mg/m^3;推焦地面站排放的颗粒物、Ba P和SO_2浓度分别为59.8 mg/m^3、0.012 mg/m^3和29 mg/m^3;焦炉顶排放的颗粒物、BSO和BaP浓度范围分别为0.56 mg/m^3~1.14 mg/m^3、0.09 mg/m^3~0.15 mg/m^3和0.10μg/m3~0.30μg/m3。

Three coking plants were selected as our research object, and the concentration characteristic of pollutants from emission sources have been analyzed systematacially. The average concentrations of particulate matter, SO_2 and NOxfrom coke oven chimney were 48.6 mg/m^3, 35 mg/m3 and 165 mg/m^3, respectively. The emission concentration of particulate matter, Ba P and SO_2 from the coking pushing station were 59.8 mg/m^3, 0.012 μg/m^3 and 29 mg/m^3, respectively. Among the pollutants from the fugitive emission at the top of coking oven, the emission concentration of NH_3 was the maximum, and ranged from 1.14 mg/m^3 to1.82 mg/m3, while the ranges of average emission concentration of particulate matter, BSO, Ba P and H_2S were 0.56 mg/m3~1.14mg/m^3, 0.09 mg/m3~0.15 mg/m3, 0.10 μg/m^3~ 0.30 μg/m^3 and 0.05 mg/m^3~0.09 mg/m^3, respectively.
