内容記述 Fundamental studies of a new type ozonizer without dielectrics have been carried out. The rate constant k[1] for O+O[2]+O[2] → O[3]+O[2] has been measured by the absorption measurements using a 253 nm line of a mercury lamp and is estimated about 2.2×10[-34] cm[6] sec[-1]. The ozone generation characteristics are also measured for various parameters, such as the charging voltage, gas mixture ratio, steepness of the waveform of the applied voltage and the gap spacing of the main electrodes so on. A new type ozonizer with double discharge also has been proposed to improve the efficiency of the ozone generation. The mixtures of He/O[2] is effective to keep the discharge stable at atmospheric pressure and the maximum efficiency of the ozone generation of about 380 g/kWh has been obtained by a small-sized ozonizer. On the other hand, the efficiency of 400-450 g/kWh has been obtained by a large-sized one. The discharge volume for each ozonizer is about 23 cm[3] and 917 cm[3] , respectively. The superposition of the high frequency corona discharge (HFCD) during the main discharge is also effective to improve the efficiency of the ozone generation. A simple electrical circuit which is able to obtain the applied voltage with the rapid rise time and control the delay time between the predischarge and the main-discharge is used. The effect of the series gap connected with the main electrodes on the ozone generation and the glow-toarc transition is studied. A coaxial cylindrical double discharge type ozonizer is made and the characteristics of the ozone generation are measured. It is confirmed that this device is able to operate stably in air at atmospheric pressure for the stored energy at least in the range of 0.05-0.8J and the ozone of about 9μg per one discharge is produced.
