【摘要】 对4种纳米光催化空气滤网的甲苯降解性能进行了测试,结果显示某进口样机光催化降解甲苯效果明显;蜂窝、铝基和纸基3种光催化空气滤网光催化效果不明显,主要靠所含活性炭的吸附作用来消除甲苯,其中纸基滤网消除甲苯效果最好。较高的甲苯初始浓度和中低迎面风速下光催化效果较好。更多还原

【Abstract】 Makes measurement of performance of four nanometer photocatalytic air filters to eliminate dilute toluene in air, the result shows that certain imported sample machine can effectively eliminate toluene by photocatalysis and that the photocatalytic effect of honeycomb, aluminium based and paper based filters is unobvious, they eliminate toluene mostly by adsorption of active carbon and the paper based filter has the best effect to eliminate toluene in the three filters. Photocatalytic effect is better at higher Initial toluene concentration and moderate and low approach air velocity.更多还原
