摘要
电碳材料燃烧排放产生的颗粒物在大气中传输和扩散受到风场和大气条件的影响,其中包括风速、温度和湿度的变化和不确定性,预测电碳材料燃烧排放的分布变得困难。因此,研究电碳材料燃烧排放对大气颗粒物浓度的影响。使用大气监测仪器收集数据,并建立高斯烟羽模型,模拟电碳材料燃烧排放颗粒物在大气中的沉积与扩散情况。将辽宁省某火电厂作为监测区域,采用线性回归分析方法分析并验证了电碳燃烧排放颗粒物浓度与气象因子之间的关系。通过不同方法对比说明:所提方法分析出的电碳材料燃烧排放对大气颗粒物浓度的影响更符合实际情况。
The transmission and diffusion of particulate matter generated from the combustion of carbon materials in the atmosphere are influenced by wind fields and atmospheric conditions,including changes and uncertainties in wind speed,temperature,and humidity.Predicting the distribution of carbon material combustion emissions becomes difficult.This study therefore analyzes the impact of combustion emissions from electrocarbon materials on atmospheric particulate matter concentration.It collects data using atmospheric monitoring instruments and establishes a Gaussian plume model to simulate the deposition and diffusion of particulate matter emitted from the combustion of carbon materials in the atmosphere.A thermal power plant in Liaoning Province was used as a monitoring area,and linear regression analysis was used to analyze and verify the relationship between the concentration of particulate matter emitted from electric carbon combustion and meteorological factors.By comparing different methods,it is demonstrated that the proposed method analyzes the impact of combustion emissions from carbon materials on atmospheric particulate matter concentration,which is more in line with the actual situation.
