利用空气负离子净化新风实验研究

Experimental Research of Fresh Air Purification with Air Negative Ion

本文根据专利“一种负离子新风净化系统”(ZL201720448691.0)搭建负离子新风净化装置,在不同的沉降斜板间距和倾斜角度下,对PM 2.5 沉降效果进行观察。实验结果表明:负离子对PM2.5 的沉降具有良好的促进作用,沉降斜板能够明显提高PM2.5 的沉降效率,沉降斜板在适当的倾斜角度下,PM2.5 沉降效果会更好,去除率有明显提高。

According to the patent “A Negative Ion Fresh Air Purification System”(ZL201720448691.0), an experimental device for negative ion fresh air purification was built. The settlement effect of PM2.5 was observed with different spacing and inclination angles of inclined plates. The experimental result shows that the negative ions have a good promotion effect on the settlement of PM2.5 , and the settling inclined plate can significantly increase the settlement efficiency of PM2.5 . The settling effect of PM2.5 will be better and the removal rate will be obviously improved under the appropriate inclined angle of the settling inclined plate.
