摘要
提出将碳化微米长木纤维作为微粒捕集器的过滤体材料,并建立相应的数学模型,通过理论和试验对其排气压降梯度进行研究。结果表明:该种材料所制成的尾气净化器过滤效率高、压降梯度小,可为柴油机尾气净化开辟一个新的方向。
Diesel powered vehicles produce a considerable amount of particulate laden exhaust gases, which is thought to be the main source of air pollution and also cause lung cancer. The diesel particulate filter（DPF） is one of the leading technologies for reducing diesel PM（ particulate material）. In this paper, utilizing carbonized micro-length wood fiber（CMLWF） as filter material of DPF is presented and a corresponding mathematic model is built for the first time. Theory and test prove that the filter efficiency of the CMLWF DPF is high, the pressure drop gradient low and performance life long, which can successively open up a new direction for reducing diesel PM.
