摘要
针对目前空气中悬浮颗粒过滤困难的问题,提出采用微米木丝和微纳米木粉组构PM2.5过滤器的目标,利用木材天然环保的过滤材料及其炭化后天然结构中的孔穴吸附功能,过滤汽车尾气、燃煤微粒等大气悬浮颗粒。文章对国内外目前过滤器进行分析,提出木基生态级负离子PM2.5过滤器的过滤机制和技术路线,通过可行性论证,将为我国采用木基材料作为空气过滤器的应用前景提出一个研究方向。
In accordance with the difficult problem of particles suspended filter in the air,this paper proposed the target of PM2. 5 filter grouped by micron wood wool and micro and nano wood flour. Using filtration material of timber natural environmental and the cavities adsorption function of its natural structure after carbonization to filter automobile exhaust, coal particles and other atmospheric particles suspended. Through analysis of filter at home and abroad,this paper proposed filtering mechanism and technical route of wood-based ecological level anion PM2. 5 filter. After feasibility demonstration,it would propose a research direction of application prospects by using wood-based materials as air filter.
