Abstract
The present invention relates to a tubular ozone generator which uses a novel electrode structure wherein a wound electrode has a solid insulator between the turns of the windings.
Claims24
An apparatus for producing ozone, comprising,
- first and second dielectric means, each further comprising first and second surfaces;
- said first dielectric means being disposed in spaced-apart relation to said second dielectric means, whereby said second surface of said first dielectric means is disposed in spaced apart and opposing relation to said second surface of said second dielectric means;
- first and second spacer means, for maintaining said first and second dielectric means in substantially spaced-apart relation to one another;
- a reaction chamber comprising the volume between said first and second dielectric means;
- said reaction chamber being adapted to receive volume of gas comprising molecular oxygen;
- first electrode means disposed in along said first surface of said first dielectric means;
- second electrode means disposed along said second surface of said second dielectric means in substantially parallel relation to said first electrode means wherein said second electrode means comprises a winding of conductive wire disposed on said second surface of said second dielectric means, said windings being separated by a solid insulator;
- means for supplying gas containing molecular oxygen to said reaction chamber;
- means for supplying electrical power to said first and second electrode means, to induce a corona discharge in said gas comprising molecular oxygen whereby said corona discharge converts some of said gas comprising elemental oxygen to ozone;
- and
- wherein said reaction chamber is adapted 1o discharge a mixed stream of gas comprising ozone and the unreacted fraction of said volume of gas comprising molecular oxygen.
