Ozone Generation Characteristic of Ceramic Reactor using Ti-Al-Si

세라믹 방전관의 오존 발생 특성

A novel ozonizer has been developed using a high frequence surface discharge and a high purity ceramic as its dielectric component. And A cylindrical thin compound ceramic catalyst in reactor is adhered to inside of the film-like outside electrode. An ac exciting voltage with frequency to 0.6 kHz from 1.0 kHz and $4{\sim}6$ kV of peak-to-peak is applied between the electrodes to produce a stable high-frequency silent discharge for generation of ozone. A substantial reduction of the exciting voltage is also enabled by using a thin ceramic. As a result, the ozonizer can easily produce ozone concentration(50 $g/m^3$ for oxygen) and power efficiency(240 g/kWh for oxygen) without using a special enrichment means.
