Al₂O₃ 유전체를 이용한 산소 / 공기 원료에 따른 오존발생기의 특성

The ozone generation is commonly made with silent discharge method using quartz glass dielectric. In this paper, using Al₂O₃ dielectric to instead of the traditional quartz glass dielectric to improve the system efficiency is presented. The dielectric was manufactured as tube shape (Internal diameter × Outside diameter: 11 × 15mm) using 99% Al₂O₃ ceramic. The characteristics of dielectric discharge and ozone generation were studied of experiments with variation of discharge power, discharge electrode space and rate of flow for supplied gas (O₂/Air). As the experimental results, in the same discharge space, the ozone concentration continuously increased with input power increasing, and ozone yield increased until saturation happened. Also, the expended power increased with discharge space extended due to discharge power increased. In additional, the ozone concentration of oxygen ozone was higher than air that was observed when using oxygen ozone in proposed experiments.
