Development of an Ozone Generator Operated with Fast Rising Voltages

摘要

An ozone generator utilizing fast-rising square-wave voltages has been contsructed, and has been istalled in a water purifying system for a swimming pool. Using a rotating spark-gap-switch, square wave voltages were generated with the peak value of 10 - 20 kV, rising time of 20 ns, and frequency of 100 - 300 Hz. At theozone concentratio nfo 6000 ppm, the energy yield of ozone gneeration of mroe than 70 g/kWh could be obtaine.d The ozone generator of 10 g/h ozone generation rate was operated continuously for 2 months without any problem, and life time of the switch was estimated to be 5 years.
