设计了一种红外再生柴油机微粒捕集器系统(Diesel Particulate Filter,DPF),采用双过滤单元捕集排气微粒。以6110A柴油机为试验用机,进行捕集器红外再生特性的试验研究。结果表明:影响红外再生性能的主要因素有微粒累积量、预热时间、红外加热器加热功率及再生用废气量等。微粒累积量和再生用废气量主要影响再生过程中过DPF内部的最高温度与平均温度,预热时间和加热器功率主要影响再生时间。试验同时表明:微粒捕集器平均再生效率超过80%,且工况适应性好。 An infrared regeneration Diesel Particulate Filter (DPF) was designed. The dual-filter unit was used to capture the exhaust particles. 6110A diesel engine as a test machine, experimental research on catcher infrared regeneration characteristics. The results showed that the main factors influencing the infrared regeneration performance are particle accumulation, preheating time, heating power of infrared heater and exhaust gas for regeneration. Particulate accumulation and the amount of exhaust gas for regeneration mainly affect the maximum temperature and the average temperature inside the DPF during the regeneration process. The preheating time and the heater power mainly affect the regeneration time. At the same time, the experiment shows that the average regeneration efficiency of particle trap is more than 80% and the adaptability of working conditions is good.
