摘要
建立了一个用于柴油机排气微粒泡沫陶瓷过滤体微波再生过程模拟计算的数学模型。通过模拟计算，对过滤体微波再生特性进行了数值预测，并对影响过滤体再生的几种主要因素进行了分析。计算结果表明，过滤体微波再生技术是可行的，再生持续时间为（１０～１５）ｍｉｎ，再生效率一般可达到８５％左右，但再生效率和再生速率受再生时间、过滤体积碳量、气流中氧含量以及气流速度大小等因素的影响。计算结果可以为再生系统的进一步优化提供理论依据。
A mathematical model is proposed for the numerical computation of the microwave regeneration process of the diesel exhaust particulate filter.In this study,the numerical prediction of the filter microwave regeneration characteristic is made and the effect of some main factors on the process of regeneration is analyzed.The results show that it is possible to regenerate the diesel particulate filters in certain conditions by using microwave energy,the regeneration duration is 10～15 minutes,the efficiency of regeneration is 85% or so,but the efficiency and rate of regeneration are affected by many factors.The results of the calculation can provide a theoretical basis for the optimal design of the microwave regeneration system.
