蒸发冷却填料过滤性能的实验研究
|
摘要
为了验证蒸发冷却填料的除尘效率,借助气溶胶粒径谱仪(Promo2000),测试干式植物纤维填料以及湿润后的植物纤维填料过滤后的空气中可吸入的颗粒物浓度.测得在密闭环境下,使用单元式蒸发冷却设备后的室内PM 10可吸入颗粒物浓度减少32.9%,PM 2.5可吸入颗粒物浓度减少21.2%.得出单元式蒸发冷却设备对空气中的可吸入颗粒物具有良好的除尘效率并受风速影响.在实际生活中可以利用蒸发冷却填料对空气进行过滤除尘,提升室内的空气品质.
In order to verify the dedusting efficiency of the evaporative cooling filler,the concentrations of respirable particulate matter in filtered air of the dry plant fiber filler and the wetted plant fibrous filler were tested using aerosol particle size(Promo 2000).In the closed environment using a unit evaporative cooling device,PM 10 inhaled particulate matter concentration decreased by 32.9%,and PM 2.5 respirable particulate matter decreased by 21.2%.It is concluded that the unitary evaporative cooling device has a good dust removal efficiency for airborne particulate matter and is affected by the wind speed.In practice,the evaporative cooling fillers can be used to filter the air,and improve the indoor air quality.
