矿山井下开采空间狭小、通风条件差,井下装载机作业时产生的尾气难以及时、顺畅排放到矿井之外,由此造成井下空间污染严重,给工作人员的健康带来极大危害。本文主要讲述井下装载机柴油机尾气的危害,提出净化方法,并介绍水洗式尾气过滤装置。1.柴油机尾气的危害柴油机尾气中有害成分主要有氮氧化物(NO_x)、碳氢化合物(HC)、 Underground mine mining space is small, poor ventilation, exhaust gas generated during downhole loader operation is difficult to timely discharge smoothly to the mine, resulting in underground space pollution, causing great harm to the health of staff. This article mainly describes the hazards of downhole diesel engine exhaust gas, proposed purification methods, and introduced washing type exhaust filter device. 1, the hazards of diesel exhaust Diesel exhaust harmful components are mainly nitrogen oxides (NO x), hydrocarbons (HC)
