| 摘 要： | 利用直流电晕自由基簇射对甲苯有机废气进行试验,分别考察了有机污染物浓度、温度、电压、湿度和停留趑时间等不同因素对去除率的影响.试验结果表明,降低气体温度和一定的湿度能够提高脱除效率,电压增高可以提高脱除效率,停留时间长使得脱除效率升高,但能量效率降低.有机物的浓度增大,会使得脱除效率降低,但同时能提高能量的利用效率.本实验的目的旨在为降解烟气中的多环芳烃(二噁英等)打下基础.

| Abstract: | Using DC corona radicals shower to decompose toluene in air, different parameters were studied, such as the concentration of toluene, temperature, voltage, humidity and the settled time. The results showed that the fall of temperature and appropriate humidity can increase the decomposing efficiency of toluene; the efficiency decreased with the increasing of the voltage; the settled time was longer, the decomposing efficiency was higher, but the energy efficiency decreased. Increasing the concentration of toluene made the removal efficiency lower, but in the same time, made the energy efficiency higher. The experiment built a good basis for researching radicals decompose PAHs(dioxins etc.). |
