隧道工程机械大多采用柴油机作为动力,因其作业环境恶劣,废气污染严重,应配备废气净化装置。本文提出的同时采用燃油添加剂、氧化催化转化器、喷水洗涤装置和涤烟剂的净化方法,经施工应用和净化前后尾气排放的测定,取得了较好的效果。 Most of the tunnel construction machinery uses diesel as the driving force. Due to the harsh operating environment and serious pollution of the exhaust gas, exhaust gas purification equipment should be provided. The proposed purification method using fuel additive, oxidation catalytic converter, water jet washing device and carbonic acid and nicotinic acid catalyst has achieved good results after application and determination of exhaust emission before and after purification.
