Development of dielectric barrier discharge-type ozone generator constructed with piezoelectric transformers: effect of dielectric electrode materials on ozone generation

摘要: The dependence of ozone generation on the types dielectric electrode material has been investigated using an generator constructed with piezoelectric transformer developed in our laboratory. is based excitation barrier discharge (DBD), which advantage a compact configuration for generating ozone. Four kinds materials are prepared electrodes. Electrical properties DBD and characteristics different materials. Differences mode among recognized discussed basis results Lissajous figures voltage–current waveforms. During continuous running generator, temporal decrease concentration observed owing to temperature increase inside reactor. Although influenced by many dielectrics, two important factors achieving high-efficiency identified this study. One use high-thermal conductivity electrode, functions well as heat sink transferring generated outside through material. other factor control mode. Our show that considered Townsend-like suitable generation.
