A DC-voltage ozone generator with a barrier discharge is described. The discharge is formed between fixed metallic electrodes placed at a small distance from both surfaces of a disc dielectric rotor, and charged sections of its surface. The discharge has the form of a series of microdischarges, the duration of whose current pulses is on the order of 10 ns. The discharge current depends on the dynamic barrier capacitance, number of electrodes, and rotor rotation rate. The quantity of the produced ozone rises with the increase in the velocity of gas traveling through the discharge gaps. The maximum output of 7 g/h at a 0.2-g/m3 ozone concentration is achieved at a 35-m3/h air consumption. The power consumption for ozone production was 12.5 kWh/kg, which is less than that of ac or pulse voltage ozonizers of the traditional design.
