Abstract:
In an ozone generating system which performs intermittent operation, that is, an operation in an ozone generating operation period in which ozone is generated by discharging gas including oxygen at a discharge electrode part and an operation in an ozone generating operation standby period in which ozone is not generated by stopping discharge are alternately repeated, a gas circulating device which circulates gas in the ozone generating apparatus and removes at least nitric acid from the gas which is circulated is connected to the ozone generating apparatus.
Abstract:
In order to improve the reliability and reduce the power consumption of a device for generating ozone in an electric field, the components (1) conducting high voltage are far enough away from the earthed components (4) not to maintain a flashover in the pure gas section at the highest voltages required and the dielectric displacement flux is concentrated by solid insulation (2) to the extent that the field strength is adequate in the gas gap (3) between the surface of the insulator (2) and the counter-electrode (4) for generating ozone.
Abstract:
An ozone generator is set forth wherein the production of ozone is increased by the more efficient cooling of the generator electrodes and therefore the discharge gap where the ozoneforms. The cooling is effected by the use of a boiling coolant fluid which has a high heat transfer capacity. Additionally the electrode structure is made more rigid for increased life in the presence of boiling cooling fluid. A method of ozone preparation is also set forth. Alternately cooling can be enhanced by the introduction of a gas into the coolant to enhance coolant turbulence without boiling the coolant.
Abstract:
The present invention is directed to a portable ozone generator for use in small, confined, uninhabited spaces, such as refrigerators. The generator has a clam shell top and bottom. The bottom is of unitary construction and houses batteries. The top house electrical components, including circuitry for time generation of ozone.
Abstract:
A corona discharge device is provided in which a corona discharge region is formed between the very narrow and small surface area line edges of two electrodes. The electrodes may be generally sheet form and each have a base portion and N protruding portions extending from the base portion (N being an integer and ≥1). The protruding portions of the electrodes are shaped and positioned to inter-mate with another to define a serpentine shaped region between the electrodes, wherein edges of protruding portions of one electrode and edges of protruding portions of the other electrode are disposed in parallel to and directly opposite one another so as to form 2N-1 corona discharge region segments therebetween. When the electrodes are energized by a high voltage AC signal a corona discharge is formed in each discharge region segment. Preferably a dielectric wafer lies about half way within each corona discharge region, and is oriented perpendicularly to the plane of the electrodes. When mounted within a chamber, an oxygen containing gas can be fed through the corona discharge regions of the device to conveniently and efficiently generate ozone. The HVAC power circuit which provides the driving AC voltage to the electrodes may also have a corona adjustment level circuit that adjusts the mark-space ratio of the AC voltage.
Abstract:
A frame-type ozone generator has a plurality of elongated electrodes deployed in substantially parallel, spaced relation to each other so as to form a substantially flat electrode array, and a flow generator for generating a flow of oxygen containing gas through the electrode array in a direction substantially perpendicular to the electrode array. Each of the electrodes is formed from an electrically conductive core covered with polyvinyl-difluoride. Preferably, each electrode array is arranged within a frame of a given area, each frame being configured for assembly with other similar frames to form an extended ozone generator of area greater than the given area. Also disclosed are an apparatus for treating a product with ozone-containing gas in which pressure-waves are used to enhance effectiveness of the ozone treatment, and a two-chamber batch method for implementing treatment of a product with possibly harmful gases such as ozone.
Abstract:
The present invention provides ozone generating apparatus for use in air conditioning systems for sterilizing the recirculated air. The apparatus can also be used in food preservation and other areas where bacteria and other micro-organisms need to be controlled. The apparatus comprises a lamp (10, 20, 40, 50, 60) consisting of a tube (11, 21, 41, 51, 61) which has an internal conductor (15) surrounded by a layer of dielectric material. Surrounding the dielectric material is a layer of metal mesh material or a printed grid of similar conductive pattern. The internal conductor is applied with a high voltage power supply, and the high voltage breaks through the dielectric material in corona discharge to the outer metal mesh. Oxygen which comes into contact with the corona discharge (electric field) is ionised forming ozone (03) which is used to disinfect infected areas.
