光等离子空气净化技术在城市轨道交通车辆中的应用

Application of Light Plasma Air Purification Technology in Metro Vehicles

在概述过滤式空气净化技术、静电式空气净化技术、臭氧空气净化技术及光等离子净化技术的基础上,对光等离子净化技术产品在轨道交通车辆加装应用的可行性进行了研究,并对车内空气中TVOC、细菌净化改善效果进行了测试。结果表明,开启净化装置2 h后,车厢内空气中细菌总数去除率为100%、TVOC去除率为90%,空调出风口和车厢中部拉手物表细菌去除率分别为98%和99%,说明光等离子净化技术可有效降低车厢内的TVOC、空气和物表细菌数量,提升车厢内空气质量。

On the basis of summarizing filtration air purification technology,electrostatic air purification technology,ozone air purification technology and light plasma purification technology,the feasibility of applying light plasma purification technology products to rail transit vehicles was studied,and the improvement effect of TVOC and bacteria purification in the air inside the vehicles was tested.The results showed that after the purification device was started for 2 h,the removal rates of total bacteria and TVOC in the air in the compartment are 100%and 90%,and the removal rates of bacteria on the surface of the air conditioner outlet and the handle in the middle of the compartment are 98%and 99%,respectively,indicating that the light plasma purification technology can effectively reduce TVOC,the bacteria amount in the air or on the surface of the compartment and improve the air quality in the compartment.
