羊毛滤料对PM2.5的过滤性能研究

Study on the Performance of PM2.5 with Wool Filter Media

从实验角度研究了羊毛滤料原样、经过纳米TiO2光催化整理后的整理样对PM2.5的过滤效率和阻力,并做了相关比较与分析。实验结果表明:随着风速的增大,相同克重的羊毛滤料对PM2.5的过滤效率逐渐降低,同时阻力大幅增加。随着克重的增加,羊毛滤料对PM2.5的过滤效率增大,过滤阻力也相应增大。经过纳米TiO2整理剂整理后,羊毛滤料整理样对PM2.5的过滤效率有所提高,但是阻力也有了相应的提高。

From the point of experiment, this paper studied the filtering performance of the wool acupuncture filter, the wool acupuncture filter after padding by nanometer TiO2 photocatalysis, Polypropylene Materials and Polypropylene Electret Materials to PM2.5, The result shows that At a certain filtrating speed, the wool filtration material＇s filtering efficiency to PM2.5 and decreased. With the increase of filtrating speed, wool filter filtering efficiency of particle decreased, while the resistance increased significantly. With the increase in density, the filtering efficiency of wool fiber to particles increased,the filtration resistance also improved accordingly.
