摘要：

利用车载被动DOAS测量系统，对某钢铁企业进行分装置绕行观测。采用了计算参与拟合截面相关性的方法，确定痕量气体最优反演波段，获取观测路径上的垂直柱浓度后，结合测量时间内的车速以及风速风向信息，计算得出区域内SO2及NO2排放净通量。实验得出某钢铁企业厂区内轧钢冶炼区域SO2与NO2排放净通量均值分别为149kg/h和372kg/h；焦化区域SO2与NO2排放净通量均值分别为260kg/h和286kg/h；电厂区域SO2与NO2排放净通量均值为21kg/h和26kg/h；石灰烧培区域SO2与NO2排放净通量均值为64kg/h和79kg/h；烧结区域SO2与NO2排放净通量均值为34kg/h和99kg/h。

Abstract:

Mobile passive differential optical absorption spectroscopy (DOAS) was used for the remote sensing of the emission flux from different systems of a steel factory. Correlation matrix of the absorption cross sections used for DOAS retrievals. Vertical column density was retrieved by this system, combined with the meteorological wind field and car speed information, the emission of SO2 and NO2 in the area was estimated. The result showed the average value of the flux of SO2 and NO2 in the rolling and smelting system was 149kg/h and 372kg/h. The average value of the flux of SO2 and NO2 in the coking system was 260kg/h and 286kg/h. The average value of the flux of SO2 and NO2 in the power system was 21kg/h and 26kg/h. The average value of the flux of SO2 and NO2 in the roasting system was 64kg/h and 79kg/h. The average value of the flux of SO2 and NO2 in the sintering system was 34kg/h and 99kg/h.
