车辆尾气排放控制技术和排放标准在近年来得到了快速发展,但非尾气管(non-exhaust)排放却很少涉及。非尾气管排放主要包括车辆制动磨损、轮胎磨损、路面磨损和车辆扬尘,本研究调查了北京典型道路车流量和车辆运行速度等参数,应用欧盟非尾气管排放因子分析车辆制动磨损、轮胎磨损和路面磨损PM10排放。结果显示:不同类型道路的排放强度在1.1~10.7kg/(km.d)之间,高速路的排放强度最大,其次为环路,其他类型道路相对较小。建立了基于GIS的北京城区机动车非尾气管排放网格分布清单,高峰小时轮胎磨损PM10排放量为386.8 kg/h,车辆制动磨损PM10排放量为176.2 kg/h,路面磨损PM10排放量为103.2 kg/h,合计非尾气管PM10排放量为666.2 kg/h。
Vehicle exhaust emission control technology and emission standards have been rapidly evolving in recent years, but non-exhaust emissions are seldom addressed. Non-exhaust pipe emissions mainly include vehicle brake wear, tire wear, road wear and vehicle dust. This study investigated Beijing typical road traffic flow and vehicle speed and other parameters, the application of the EU non-exhaust pipe emission factor analysis of vehicle braking wear, tires Wear and Pavement Wear PM10 Emissions. The results show that the emission intensity of different types of roads is between 1.1 ~ 10.7kg / (km.d), the discharge intensity of expressway is the largest, followed by the loop, while the other types of roads are relatively small. A GIS-based grid distribution list of non-exhaust pipelines for motor vehicles in urban Beijing was established. The emission of PM10 was 386.8 kg / h for peak hour tires, 176.2 kg / h for vehicle brake wear and PM10 emissions for pavement wear were 103.2 kg / h, total PM10 emissions of non-exhaust pipe is 666.2 kg / h.
