低温等离子体在废气处理中的应用

Application of Low Temperature Plasm in Exhaust Gas Treatment

目前对异味恶臭废气的常用处理方法存在运转费用高、设备及运行管理要求高、占地面积大、净化效率不高、极易产生二次污染、易受污染物浓度及温度影响等缺点。低温等离子体降解污染物是利用高能电子、自由基等活性粒子与废气中的污染物作用,使污染物分子在极短的时间内发生分解,以达到降解污染物的目的。通过山东某制药公司废气处理项目应用实例,显示出低温等离子体处理废气的效果和经济效益的优势。

The treatment methods for exhaust gas of peculiar smell and malodor show shortcomings, such as high op- eration costs, strict requirement of equipment and operation management, big area of land required, low purification eficiency, the secondary pollution caused, influence of pollutant concentration and temperature, Pollutant is degraded by low temperature plasm that uses the effect of active particle and pollutant of energetic electron and free-radials and cause the degradation of pollutant molecule in a short periood of time so as to degrade the pollutants. Through the application example of exhaust gas treatment project in a certain pharmacy company of Shandong, it shows the effect of low temperature plasm in treatment of exhaust gas and the advange of economic benefits.
