| 摘 要： | 为对水泥行业实现大气污染排放动态监测，反映污染排放的时空分布特征，提出基于热异常点探测数据的新型干法水泥气态污染物排放量测算方法.利用VIIRS热异常点的FRP(fire radiation power，辐射功率)参数结合水泥产业结构特点，建立FRP与污染物排放之间的定量估算关系.利用2013—2017年北京市水泥生产统计信息和热异常点探测数据进行了大气污染排放评估，结果显示:①利用热异常产品的FRP参数估算北京市水泥厂的污染排放水平，利用NOx和SO2排放量的统计数据对排放估算值进行相关性验证，二者统计值与估算值之间的相关性系数分别为0.65和0.63.②2013—2017年北京市所有水泥厂的热异常点数据与环境统计数据中水泥总产量、熟料总产量、煤炭总产量以及NOx、SO2和烟(粉)尘排放量的相关性均较好，相关性系数均在0.7左右.③自2013年以来，北京市金隅琉水环保科技有限公司和北京金隅北水环保科技有限公司的热异常点数均呈下降趋势.由于采取了减排措施，水泥总产量和污染排放量也均呈逐年减少的趋势.研究显示，基于热异常点探测数据的新型干法水泥气态污染物排放量测算方法可快速获取水泥厂的位置信息、热释放规模，结合污染排放因子可间接评估水泥厂NOx和SO2等主要污染物的排放情况.

| Abstract: | In order to realize the dynamic monitoring of air pollution emissions in the cement industry and reflect the distribution characteristics of pollutant emissions, a new method for measuring air pollution emissions from new dry cement is explored by thermal anomaly detection data. The fire radiation power (FRP) parameters of VIIRS thermal anomaly detection data are applied to establish a quantitative estimation relationship between FRP and pollution emissions, combined with the characteristics of the cement industry structure. Based on the statistical information of cement production and thermal anomaly data in Beijing from 2013 to 2017, the assessment of air pollution emission is carried out and results show that:(1) The correlation coefficients are 0.65 and 0.63 respectively by using the FRP parameter of thermal anomaly to estimate the cement plants pollution emission level in Beijing. The statistical data of nitrogen oxide and sulfur dioxide emission is used to verify the correlation of emissions estimates. (2) During the period of 2013-2017, the thermal anomaly data of all cement plants in Beijing has a good correlation with the total output of cement, the total output of clinker, the total output of coal, and the emissions of nitrogen oxide, sulfur dioxide, and flue gas (powder) dust, with the correlation coefficient of about 0.7. (3) Since 2013, the account of thermal anomaly points has decreased in Beijing Jinyu Liushui Environmental Protection Technology Co., Ltd. (Jinyu Liushui) and Beijing Jinyu Beishui Environmental Protection Technology Co., Ltd. (Jinyu Beishui). Due to the emission reduction measures, the total output and pollution emissions of cement have decreased over the years. The new dry cement gaseous pollutant emission measurement method based on the thermal anomaly detection data can quickly obtain the location information and heat release scale of the cement plant. Combined with pollution emission factors, the emission of the main pollutants such as nitrogen oxide and sulfur dioxide from cement plants can be evaluated. |
