1965年以来,国内做了大量的现场试验,对东风_1型(2000马力)内燃机车通过隧道时,对隧道内空气的污染情况有了较详细的了解,从而可针对不同情况,采取防治措施,使隧道内作业人员免受或减轻有害气体对身体健康的危害。本文简略介绍东风_1型内燃机车废气中有害气体的成分、浓度和分布规律等试验资料,供对运营隧道有害气体采取综合防治措施时参考。一、内燃机车废气中有害气体的成分内燃机车废气中有害气体的成分与所用的柴油以及机车的构造、性能等有较大的关系,
Since 1965, a large number of field trials have been conducted in China. When a diesel locomotive of Dongfeng-1 (2000 horsepower) passes through a tunnel, the pollution of the air in the tunnel is well understood. Therefore, prevention and control measures can be taken for different situations So as to prevent workers in tunnels from or reduce the harmful effects of harmful gases on their health. This article briefly introduces the experimental data of the composition, concentration and distribution of harmful gases in the exhaust gas of Dongfeng-1 diesel locomotive for reference when taking comprehensive prevention and control measures for harmful gases in the operation tunnel. First, the composition of harmful gases in the exhaust gas of a diesel locomotive The composition of the harmful gas in the exhaust gas of a diesel locomotive has a great relationship with the structure and performance of the used diesel and the locomotive,
