| 摘 要： | 提出一种柴油机排气微粒捕集器过滤体布置方式,捕集器中采用若干端截面为扇形的单元块过滤体,呈圆周排列并在微波再生时作轴向旋转。分析了单元块旋转式过滤体捕集器的过滤及再生机理,并与传统的整体式过滤体微粒捕集器的压降特性及捕集效率进行比较,对其再生效果进行评价。试验研究表明,采用单元块旋转式过滤体能较好地实现微粒捕集器连续再生,其性能优于整体式过滤体,并有效地解决了车载电源功率对微波再生技术的限制。

| Abstract: | A new rotary unit-block diesel particulate filter(DPF) was developed.There were several unit blocks with fan-shaped cross-section in the filter.These blocks were arranged in a circle and axial rotation during regeneration with microwave.The mechanism of the rotary unit-block DPF on the filtration and regeneration were analyzed and the filtration efficiency,the pressure drop characteristic were compared with the traditional overall body filter.The experimental study shows that rotary unit-block DPF is a bett... |
