Abstract:
This invention relates to an ozone generator for deodorizing and sterilizing without doing harm to a human body, and being applied to general home appliances, includes a discharger for discharging using high voltage generated from a high-voltage generating portion and an ozone generator for generating ozone by secondary-discharging with a medium of metal inside of the discharger. Thus, ozone can be generated in a place of high temperature, humidity and much dust and at a lower cost, and since a glass tube, a glass bar and a ceramic stick are employed, product cost is reduced.
Abstract:
A generator cell includes a high voltage assembly having a high voltage electrode, a low voltage assembly having a low voltage electrode, a barrier dielectric between the electrodes defining a discharge region for producing a reactive gas, and a welded seal joining the assemblies to create a permanently sealed chamber between the assemblies including the discharge region. The generator cell may have a gap in the discharge region of 0.005 inch or less. The cells may be modularly combined to form a reactive gas generator system.

The invention relates to an electrode for an ozone generator of the type comprising an outer electrode having an inner surface made of dielectric material and an outer surface comprising an electric conducting material; an inner electrode having an outer surface, said inner electrode being concentrically positioned inside the outer electrode; a gap positioned between said inner and outer surfaces; means for circulating an oxygen containing gas through said gap; means for applying a potential difference between said inner and outer surfaces; means for cooling the inner electrode; and means for cooling the outer electrode; wherein said inner electrode comprises: a massive member of heat and electric conducting material whose at least a portion of the outer surface is provided a plurality of protrusions defining a plurality of points; at least one inner duct having opposite opened ends, provided in the massive member and defining an inner surface to said inner electrode, said inner duct being intended to allow a flow of cooling gas to circulate therethrough and contact said inner surface; said electrode having such a mass and outer surface that it can work as a heat sink to collect heat generated at its outer surface and bring it at a regulated heat flow to its inner surface where it can be collected by the cooling gas. The invention also relates to an ozone generator comprising such an inner electrode and to a method of use of said ozone generator.
Abstract:
A corona discharge ozone generator has an inter-electrode gap established by dielectric spacers that engage gap confronting surfaces and are distributed in the gap so that the electrodes need not be self-supporting. Also, gas flow impedance material, which can include the gap spacers, is distributed in the gap to ensure substantially uniform flow of an oxygen containing gas.
Abstract:
In an ozone generator, spring elements (5) of metal pointing transversely to the longitudinal direction of the tube are provided for spacing the dielectric (3) from the metallic outer electrode (1). These spring elements are either bonded directly to the dielectric (3) and are stuck onto a tape-shaped carrier which is attached to the dielectric (3) and at their free ends rest against the inside wall of the outer electrode (1). In this manner, the discharge gap is only minimally constricted and the assembly of the inner tubes (2a, 2b) is simplified.
Abstract:
A flat plate corona cell for generating ozone with a generally convergent radial gas flow. The net gas flow direction through the corona gap is from the outer edges of the cell inward towards an exit port in the approximate center of the cell. This eliminates parasitic arcing at the perimeter, greatly increases the life of the perimeter seal, and provides a homogenous gas flow which increases ozone output. The cell design allows both electrodes to be operated at high voltage, therefore reducing the effective kilovolts with respect to ground by half.
Abstract:
Disclosed herein is an apparatus and method for the production of ozone gas comprising: a parallel resonance circuit formed by a high voltage transformer and a companion flexible polymeric corona discharge chamber which encloses an electrode and serves as both a passageway and reservoir for oxygen bearing gas, and a fluid counter-electrode, all contained within an appropriate enclosure. Said corona discharge chamber possesses an electrical reactance which can be varied in order to match the electrical reactance of a companion high voltage transformer so that the components resonate, hereby maximizing the transfer of energy to the corona discharge gap. The dwell of corona discharge is further enhanced by an electrostatic potential incorporated across said tube wall (electret effect). Heat formed in said discharge gap (detrimental to ozone production) is advantageously transferred to said fluid counter-electrode which also serves as an electrolytic connection between said high voltage transformer and said corona discharge chamber. Within said chamber, relatively large volumes of oxygen may be exposed to the high field density, ozone producing, resonating discharges as consequence of its flexible and linear design. The apparatus and methods described herein permit and encourage the use of intermittent and cyclic application of resonating energy and therefore achieves an improved degree of electrical efficiency. The teachings of the present invention make practical the use of alternative sources of energy for the private and commercial generation of ozone gas.

A sealed glass tube having an electrical conductor therein arranged when combined with a high voltage and an encircling perforated metal member on the tube to produce ozone. The tube has an electrically conducting cap fitted on and integrally secured to one end thereof, and an externally threaded adapter is mounted on the cap for quick attachment to and detachment from an ozone generator manifold. The conductor has a projecting end secured to an outer end wall of the cap, and such wall in turn has a lug attached thereto providing quick attachment to a source of high voltage.

A substantially tubular-shaped ozone generator embodying an inner electrode, a coaxial outer electrode surrounding the inner electrode and a tube member formed of dielectric material arranged between the inner electrode and the outer electrode. Within the tube member formed of dielectric material there is arranged a substantially cylindrical core provided at its outer surface with one or a number of substantially helically-shaped grooves extending in the axial direction of the core and forming a throughpass channel for the medium to be ozonized and the ozone which is generated.
