摘要:
为对水泥行业实现大气污染排放动态监测,实时反映污染排放时空分布特征,本研究提出基于热异常点探测数据的水泥生产排放评估方法。该方法可快速获取水泥生产的位置信息、热释放规模及其变化,并结合污染排放因子间接评估出水泥厂NOx和SO2等主要污染物的排放情况。利用2013~2017年北京市的水泥生产统计信息,结合热异常点探测数据,进行了相关性分析,发现热异常点的FRP(热辐射功率)与水泥厂的产能、煤炭消耗和污染排放都呈明显正相关。据此相关关系,结合大气污染排放因子,提出了基于热异常点数据的新型干法水泥气态污染物排放评估模型,估算北京市水泥生产的大气污染排放水平的动态变化。监测结果显示:2013年以来,由于采取了减排措施,金隅琉水和金隅北水的水泥总产量和污染排放量成逐年减少的趋势,与此同时热异常点数也整体呈下降趋势。

Assessment of air pollution emission from industrial sources in Beijing based on thermal anomaly detection——taking cement production as an example
QIU YUN
Abstract:
Air pollution discharge evaluation was studied to reflect the spatial and temporal distribution characteristics of pollution discharge dynamically. This evaluation method can acquire the location information, heat release scale and heat variation of cement production immediately. The discharge of NOx and SO2 can also be estimated indirectly with other pollution emission factors based on this method. Correlation analysis was carried out between Beijing cement production statistical information and thermal anomaly points remote sensing data. The result showed that FRP (thermal radiation power) of thermal anomaly points was positively correlated with the productivity, coal consumption and pollution discharge of cement plants based on the data from 2013 to 2017. According to this result, a gaseous pollutant emission evaluation model designed for the new dry process cement production was proposed to estimate the dynamic change of air pollution emission from cement production in Beijing based on thermal anomaly data. The evaluation results show that the total cement production and pollution emissions of Jinyu Liulihe cement plant and Beijing cement plant have been decreasing since 2013, due to the adoption of emission reduction measurements. The amount of thermal anomalies of these 2 plants are also showed a decrease trend.
