Abstract:
A plurality of air-tight corona generating cells of a corona generator are supported in a liquid-tight housing where they are immersed in a dielectric liquid such as transformer oil for preventing arcing between the edges of the two electrodes of each corona generating cell. The dielectric liquid is in heat exchange relationship with the external surface of each electrode and is circulated between a cooler and the housing for cooling the electrodes. A center support disc located between the electrodes of a cell unexpectedly increases the ozone yield.

Abstract:
An electro chemical conversion cell that can break down certain gasses to provide ozone and monovalent oxygen from a supplied volume of a suitable 02-containing gas. The conversion cell is provided with at least one metal mesh electrode within a generator reaction chamber, and a power supply which is adapted to supply a high alternating electric current voltage to at least partially break-down O2 in the input gas to yield ozone. A fluid flow passage extends through the reaction chamber as a generally elongated passage through the reaction cavity. The fluid flow passage extends from an upstream end, where the O2-containing gas is initially supplied into the housing, to a downstream end where treated gas either flows outwardly therefrom under pressure or is evacuated from the housing. In a simplified construction, the fluid flow passage is delineated by a series of electrically insulating plates and/or spacers which are used to partition the reaction cavity.
Abstract:
An ozone generation cell has a first conductor generally having a line geometry and a second conductor having a first groove formed in a surface thereof, and having first and second flanks on opposite sides of the first groove. The second conductor and the first groove are arranged such that the first groove follows the first conductor in parallel spaced-apart relation. The ozone generation cell also has a first dielectric having a first passage-defining portion positioned between the first conductor and the first groove. The first dielectric has first and second side portions on opposite sides of the passage-defining portion that are generally parallel to the first and second flanks respectively. The first passage-defining portion is spaced-apart from only one of the first conductor and the first groove to form a first fluid passageway defined in part by the first passage-defining portion.

An ozone generation cell is disclosed. The ozone generating cell has a first conductor generally having a line geometry and a second conductor having a first groove formed in a surface thereof, and having first and second flanks on opposite sides of the first groove. The second conductor and the first groove are arranged such that the first groove follows the first conductor in parallel spaced-apart relation. The ozone generation cell also has a first dielectric having a first passage-defining portion positioned between the first conductor and the first groove. The first dielectric has first and second side portions on opposite sides of the passage-defining portion that are generally parallel to the first and second flanks respectively. The first passage-defining portion is spaced-apart from only one of the first conductor and the first groove to form a first fluid passageway defined in part by the first passage-defining portion, for conducting fluid from which ozone may be obtained when an electric field of sufficient strength is produced in the first fluid passageway by a potential applied across the first and the second conductors.

Abstract:
A reactive gas generator cell includes a high voltage assembly having a high voltage electrode plate and a low voltage assembly having a low voltage electrode plate. Each of the high and low voltage assemblies may include a cover plate and a channel plate. A welded metallic seal may join the high voltage assembly and the low voltage assembly to create a permanently sealed chamber between the assemblies. A refractory metal surface, which may be a tungsten surface, is disposed on at least one of the low voltage electrode plate and the high voltage electrode plate. A dielectric barrier is disposed between the high voltage electrode plate and the low voltage electrode plate. A discharge region for confining a reactive gas is defined, at least in part, by the refractory metal surface and a surface of the dielectric barrier. A spacer, which may be formed from a refractory material, may be positioned between the surface of the dielectric barrier and the refractory metal surface to define a predetermined gap.
Abstract:
There is provided a highly efficient and compact ozone generating apparatus in which a very short air gap of about 0.2 mm is formed at high accuracy. Non-discharge portions are dispersed and disposed to cover an entire discharge space, or a spacer is provided to form the non-discharge portion. Further, an elastic body is mounted on a back face of an electrode, thereby enhancing an air gap accuracy of the discharge space.
