摘　　要：柴油车排放的纳米级碳烟颗粒对环境造成的污染极为严重。针对这一问题,研制新型炭化微米木纤维过滤材料,利用炭化微米木纤维滤芯对柴油车尾气中的碳烟颗粒进行吸附;根据巨正则系综蒙特卡罗法对其吸附机理进行深入研究,计算纳米级碳烟颗粒吸附数密度;通过实验加以验证。结果表明,炭化微米木纤维虑芯对纳米级碳烟颗粒吸附效率高,模拟计算方法可行,可为滤芯各项参数的优化设计提供科学的理论支持。With the increasing number of diesel vehicles, environmental pollution are made by nano-soot particles emitted by diesels badly. In order to solve this problem, a new Carbonized Micron Wood Fiber （CMWF） material is developed and used in filtering the soot particles. Meanwhile, the adsorption mechanism of the nano-soot particles is researched based on Grand Canonical Ensemble Monte Carlo （GCEMC） method and the adsorption number density is simulated. Furthermore, the simulated result is validated by test, and the test result shows that the adsorption efficiency of the CMWF filters is high, the simulation method is feasible and the scientific theory support for optimizing design properties of CMWF filters can be provided.
