柴油机尾气中颗粒污染物防治技术

摘要

柴油机排放尾气中含有大量污染物,对环境和人体健康造成很大的威胁,国家排放标准的提高促进柴油机尾气排放治理技术的革新.本文主要针对柴油机尾气中的颗粒污染物,综述现有的柴油机机外尾气颗粒物防治技术措施,并对比了各技术在工程实践上的优缺点和适用工况.%Diesel exhaust contains large quantities of pollutants which cause great threat to the environmental and human health. The exhaust emission control technologies innovate rapidly with the improvement of the diesel emission standards. Mainly aiming at the particulate contamination in the diesel exhaust, the paper reviews the outside control technologies of diesel engine exhaust particulates. The advantages and disadvantages of each technology and applicable conditions in engineering practices are compared.
