ABSTRACT:
A corona discharge generator is disclosed, and includes a central tube of electrically conducting material circumscribed by a glass tube having an electrically conducting coating on its exterior surface and being sealed to the exterior surface of the central tube at opposites ends of the glass tube. The central tube is blocked within the longitudinal extent of the glass tube, and provided with holes between the interior of the central tube and the annular enclosure formed between the central tube and the glass tube, toward the opposite ends of the glass tube. Oxygen-containing gas flows along the central tube, out a first hole or holes to the enclosure, along the enclosure and back through one or more holes into the central tube on the downstream side of the blockage. A pulsed electrical signal is applied to the two tubular electrodes to effect a corona discharge within the enclosure, thereby producing ozone. An electrical circuit is disclosed to provide such a pulse signal of variable frequency whereby the rate of production of ozone may be selected.
