- An innovative ozonizer has been developed using a high frequency, surface discharge and a high purity Ti-Si-Al ceramic catalyst as a dielectric component. Using a type of thin film, a thin cylindrical compound ceramic catalyst layer was adhered to the outside surface of its inner electrode. An alternating current (AC) exciting voltage with frequencies from 0.6 kHz to 1.0 kHz and peak-to-peak voltages of 4-6 kV was applied between the electrodes to produce a stable high-frequency silent discharge. A substantial reduction of the exciting voltage was also enabled by means of a thin Ti-Si-Al ceramic catalyst tube. As a result, the ozonizer can effortlessly obtain the required ozone concentration (50-60 g/㎥ for oxygen) and high ozone efficiency consumption power (180 g/kWh for oxygen) without the assistance of any particular methods. For purposes of this experiment, oxygen gas temperature was set at 20c, with an inner reactor pressure of 1.6 atm at 600 Hz and a flow rate of 2 l/min.
