| 摘 要： | 工程机械在高原地区运行时有害气体(尾气)CO、HC等的排放量较大,为了给高原地区隧道施工等地下工程通风设计与污染控制提供科学依据,依托关角隧道工程,对高原隧道施工中所使用的装载机、挖掘机、自卸汽车等内燃设备所排放的有害气体进行了测试,并对测试结果采用多项式拟合的方法进行拟合。研究结果表明:高原环境下工程机械排放的有害气体(尾气)CO、HC排放量以指数方式变化,随着转速增大而增大;过量空气系数φa减小时排放量增大,反之,φa增大时排放量减小。 |
| 关 键 词： | 机械工程 高原隧道 施工通风 工程机械 有害气体(尾气) 排放特性 |

| Abstract: | In pleatu regions,the engineering machinery has more harmful emission such as CO and HC.In order to provide scientific basis for ventilation design and pollution control of the tunnels in plateau,based on the construction of Guanjiao tunnel,the harmful gas from the loaders,excavators and dump vehicles was tested,the emission characteristics of harmful gas from engineering machinery under tunnel construction in plateau regions was studied by the way of polynomial fitting.The results show that the harmful gas... |
| Keywords: | mechanical engineering tunnel in plateau construction ventilation engineering machinery harmful gas emission characteristic |
