DC-voltage ozone generation

A DC-voltage ozone generator with a barrier discharge is described. The dis charge is formed between fixed metallic electrodes placed at a small distan ce from both surfaces of a disc dielectric rotor, and charged sections of i ts 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 cu rrent depends on the dynamic barrier capacitance, number of electrodes, and rotor rotation rate. The quantity of the produced ozone rises with the inc rease in the velocity of gas travelling through the discharge gaps. The max imum output of 7 gk at a 0.2-g/m(3) ozone concentration is achieved at a 35 -m(3)/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 t raditional design.
