摘要

设计了一种具有2个平面电极和6个接地条电极的三电极混合体积/表面介质阻挡放电(V-SDBD)结构，以增强放电等离子体的生成，从而降解气态苯。两个平面电极分别由5khz交流发电机和50hz交流发电机供电。与50 Hz交流发电机激励的典型双电极体积DBD (VDBD)反应器相比，混合V-SDBD反应器具有更低的起始放电电压和更好的放电均匀性，在相同能效下，V-SDBD反应器的苯降解效率是VDBD反应器的1.12倍。此外，HVE-II上电压的增加促进了苯的降解，但降低了苯降解的能量效率。

The discharge characteristics and benzene degradation performance of a three-electrode DBD reactor powered by dual AC power generators

A three-electrode hybrid volume/surface dielectric barrier discharge (V-SDBD) configuration with two plane electrodes and six grounded strips electrode was designed for enhancing the generation of discharge plasma to degrade gaseous benzene. Two plane electrodes were separately powered by a 5 kHz AC generator and a 50 Hz AC generator, respectively. Compared with the typical two-electrode volume DBD (VDBD) reactor excited by 50 Hz AC generator, the hybrid V-SDBD reactor has lower onset discharge voltage and better discharge homogeneity, and the benzene degradation efficiency of V-SDBD was 1.12 times higher than that of VDBD at a similar energy efficiency. Moreover, an increase in the voltage on HVE-II promoted benzene degradation, but decreased the energy efficiency of benzene degradation.
