Abstract

An ozone generator includes a high-voltage electrode and at least one counter electrode, which define an interstice in which at least one dielectric is arranged and through which a gas flows in the flow direction, the high-voltage electrode and the at least one counter electrode being provided with a connection for an electrical voltage supply to generate silent discharges, and a wire fabric being arranged in the gas flow and its density decreasing in the flow direction.

First claim

The invention claimed is:

1. An ozone generator comprising:
a high-voltage electrode;
at least one counter electrode,
an interstice defined between the high-voltage electrode and the at least one counter electrode and configured to permit gas flow in a flow direction,
at least one dielectric disposed in the interstice,
a connection for an electrical voltage supply to the high-voltage electrode and the at least one counter electrode for generating silent discharges,
wherein a wire fabric, disposed in the gas flow, has a density that decreases in the flow direction.

2. The ozone generator according to claim 1 , wherein a free cross-sectional area of the fabric increases in the flow direction.

3. The ozone generator according to claim 1 , wherein the fabric is a mesh, the mesh size of which continuously increases in the flow direction.

4. The ozone generator according to claim 1 , wherein the high-voltage electrode is formed at least partially of the fabric.

5. The ozone generator according to claim 1 , wherein the at least one counter electrode and the high-voltage electrode are plates that form a plate ozone generator.

6. The ozone generator according to claim 1 , wherein the at least one counter electrode and the high-voltage electrode are tubular and aligned concentrically to one another, and the fabric defines a round hollow line.

7. The ozone generator according to claim 1 , wherein the ozone generator includes a single counter electrode, the high-voltage electrode comprises the fabric, and the dielectric is arranged in contact with the single counter electrode.

8. A wire fabric for use in a gas flow of an ozone generator, wherein a density of the fabric in the gas flow decreases in a flow direction determined by the gas flow.

9. The wire fabric according to claim 8 , wherein a free cross-sectional area of the fabric increases continuously or in sections in the flow direction.

10. The wire fabric according to claim 8 , wherein the fabric is a mesh, the mesh size of which increases in the flow direction.

11. The wire fabric according to claim 8 , wherein the fabric is a wire mesh, with a multi-part design with individual sections, wherein the fabrics of the individual sections have different densities.

12. The wire fabric according to claim 11 , wherein the individual sections each have a constant mesh width, wherein the mesh width increases in the flow direction from one section to the next.

13. An electrode arrangement comprising:
a central electrically non-conducting rod,
a fabric surrounding the central electrically non-conducting rod, and
a dielectric tube surrounding the fabric, that can be impinged upon by a gas flow through the fabric,
wherein a density of the fabric in the gas flow decreases in a flow direction determined by the gas flow.

14. The electrode arrangement according to claim 13 , wherein a free cross-sectional area of the fabric increases continuously or in sections in the flow direction.

15. The electrode arrangement according to claim 13 , wherein the fabric is a mesh, the mesh size of which increases in the flow direction.
