    摘要:

    提出一種柴油機(jī)排氣微粒捕集器過(guò)濾體布置方式,，捕集器中采用若干端截面為扇形的單元塊過(guò)濾體，呈圓周排列并在微波再生時(shí)作軸向旋轉(zhuǎn),。分析了單元塊旋轉(zhuǎn)式過(guò)濾體捕集器的過(guò)濾及再生機(jī)理,，并與傳統(tǒng)的整體式過(guò)濾體微粒捕集器的壓降特性及捕集效率進(jìn)行比較,對(duì)其再生效果進(jìn)行評(píng)價(jià)。試驗(yàn)研究表明,，采用單元塊旋轉(zhuǎn)式過(guò)濾體能較好地實(shí)現(xiàn)微粒捕集器連續(xù)再生,，其性能優(yōu)于整體式過(guò)濾體，并有效地解決了車載電源功率對(duì)微波再生技術(shù)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 better solution to continuous regeneration and has better performance. It is able to break the power restriction when used for vehicle.
