Abstract
In order to meet the increasingly stringent environmental standards and promote the implementation of exhaust gas treatment for non-road mobile machinery in open-pit mines,this article analyzes the current situation and hazards of exhaust emissions from non-road mobile machinery in open-pit mines,and studies the current application status of various pollutant treatment technologies for particulate matter,nitrogen oxides,carbon monoxide,and hydrocarbons in the exhaust gases,and provides an outlook for the development of treatment technologies.The results show that the joint use of diesel oxidation catalyst,diesel particulate trap,particulate oxidation catalyst,selective catalytic reduction technology and exhaust gas recirculation technology can effectively purify the exhaust gas of non-road mobile machinery in open-pit mines.关键词
