Abstract

図 Abstract Air filters have been commonly used for the removal of airborne particles. Currently the major concerns of air filters are （ 1 ） improvement of collection performance - a filter with a low pressure drop and a high collection efficiency, （ 2 ） influence of dust load on filter performance - prediction of filter life and development of a filter with a longer life, and （ 3 ） collection efficiency of nanoparticles - thermal rebound of sub -10 nm particles on fiber surfaces. In addition to the conventional usages of air filters, they may also be used for the classification of aerosol particles by tuning the filter structure and filtration conditions. Inertial filter is a low - pass filter, which may be used for the sampling of atmospheric particles and continuous measurement of PM 2 . 5 or PM 0 . 1 . The bounce - off of particles on fiber surfaces may be utilized to achieve “sieving” of aerosol particles. Another topic of filter is the collection efficiency of air filter for PM 2 . 5 . Combination of centrifugal force with air filter may solve many problems which the conventional air filters are confronted with now.

空气过滤器的现状及新应用的探索

摘要空气过滤器已被广泛用于去除空气中的颗粒。目前空气过滤器的主要关注点是(1)提高收集性能——低压降和高收集效率的过滤器;(2)粉尘负荷对过滤器性能的影响——过滤器寿命的预测和更长的过滤器的开发;(3)纳米颗粒的收集效率——亚-10纳米颗粒在纤维表面的热反弹。除了空气过滤器的常规用途外，它们还可以通过调整过滤器结构和过滤条件来对气溶胶颗粒进行分类。惯性滤波器是一种低通滤波器，可用于大气颗粒物的采样和pm2的连续测量。5点或下午6点。１．颗粒在纤维表面的反弹可以用来实现气溶胶颗粒的“筛分”。过滤器的另一个话题是空气过滤器对pm2的收集效率。５．离心力与空气滤清器的结合可以解决目前传统空气滤清器面临的许多问题。
