摘要
将双极性脉冲高压引入介质阻挡反应器(螺旋棒式不锈钢电极、石英玻璃介质),分别对氯苯和甲苯的分解特性进行了实验研究.结果发现,这种放电形式可以高效注入能量,兼有脉冲电晕放电和介质阻挡放电的特点.脉冲高压使电场强度急剧增强,瞬间产生大功率放电和高能粒子,可以实现对VOCs化学键的高效裂解.与工频交流高压、单极性脉冲高压的试验结果比较表明,双极性脉冲高压取得了最高的降解效果;氯苯比甲苯难以分解.
Ambipolar pulse high voltage was introduced into dielectric barrier reactor （quartz glass medium and stainless-steel electrode with screw） to test study the decomposition character of Chlorobenzene and toluene. This electric discharge way could inject effectively energy, and had both the characters of pulse corona and dielectric barrier discharge. Pulse high voltage enhanced rapidly the intensity of electric field, and produced instantaneously strong discharge and highly energized particles and could realize highly effective fission of chemical bonds of VOCs. Comparing the test results of working frequency interflow high voltage and monopolar pulse high voltage, showed that highest removal efficiency was gained with ambipolar pulse voltage; chlorobenzene was removed more difficultly than toluene.
