摘要: 针对煤矿井下无轨胶轮车尾气污染物排放严重超标,难以满足非道路国Ⅳ排放标准的问题,设计了由“废气再循环(Exhaust Gas Recirculation,EGR)+氧化催化器(Diesel Oxidation Catalyst,DOC)+催化型颗粒捕集器(Catalyst Diesel Particulate Filter,CDPF)+防爆水冷结构”组成的尾气净化系统;利用GT-Power仿真软件建立催化器模型,分析了排气参数对DOC催化反应的影响规律;在此基础上,针对TDE6105DZLQFB02非道路国Ⅲ防爆柴油机研制了尾气净化装置并进行了柴油机性能及排放特性的对比试验。试验结果表明:加装尾气净化装置后,试验车辆在各工况下的CO、HC、NOx、PM的净化效率分别达到了96.80%、50.95%、25.50%、95.20%,可满足非道路国Ⅳ排放法规限值。Abstract: In view of the serious excessive emission of tail gas from trackless rubber tyred vehicle in coal mines,which is difficult to meet the non-road national stage Ⅳ,a tail gas purification system composed of “Exhaust Gas Recirculation(EGR) + Diesel Oxidation Catalyst (DOC) + Catalyst Diesel Particulate Filter (CDPF) + explosion-proof water cooling structure” was designed. GT-Power simulation software was used to establish the catalyst simulation model, and the influence of exhaust parameters on the catalytic reaction of DOC was obtained. On this basis,the tail gas purification device was developed for the explosion- proof diesel engine of TDE6105DZLQFB02 non-road national stage Ⅲ, and the performance and emission charateristics of the diesel engine were compared. The test results show that after the tail gas purification device is installed,the purification efficiency of CO,HC,NOx and PM of the test vehicle under each working condition reaches 96. 80%,50. 95%, 25. 50% and 95. 20% respectively,which can meet the limit of non-road national stage Ⅳ.
