Abstract:
An apparatus and method for generating ozone is provided. An ozone generator comprises a substantially transparent element having ozone-generating means mounted on an inner element area and an outer element area. An enclosure is positioned over the element, and an oxygen-containing gas is directed through the inner element area, creating ozone from a portion of the oxygen-containing gas. The ozone and oxygen-containing gas is then redirected over the outer element area, so that the oxygen-containing gas is at least twice exposed to the ozone-generating means, thereby generating additional ozone.
Abstract:
The present invention relates to methods and forms of apparatus for sterilizing various objects with ozone. The contents of a container may be sterilized by attaching a lid with an ozone generator to the container and generating ozone. Clothing may be treated by attaching the clothing to an ozone generator with a housing in the shape of a clothes hanger and generating ozone. Alternatively, the ozone generator in the shape of a clothes hanger may be placed in a closet with clothing to be treated. The power supply for the ozone generator may be a portable power supply, or power may be supplied from an adapter from an electrical outlet. Shoes may be deodorized by placing an ozone generator with an oblong shape in the shoes and generating ozone. A medical device may be sterilized by attaching the medical device to a sterilizing tip attached to a tubular screen, where the tubular screen is attached to the tip at one end and to an ozone generator at the other end, energizing the ozone generator and passing an oxygen-containing gas through the ozone generator to generate ozone.
Abstract:
The invention provides for the generating of a corona or other electric discharge and provides for the passing of a gas through the corona to effect ionizing, creating of ozone or the like. The ionized gas, ozone, etc., may be used for various purposes, such as the disinfecting of water or some other material, the filtering of one material, such as iron, minerals, or other materials, from another or other function. According to various methods of the invention, a corona discharge (or other electric discharge) is created, a gas is passed through the corona discharge; mixing of the gas may be provided by motionless mixing technique for one or more purposes, such as to assure maximum exposure of the gas to the corona discharge, to provide uniform temperature of the gas, to cool the corona generator, etc. According to one of the methods, too, a corona generator has an equivalent circuit of a plurality of capacitors, which may be charged in series and rapidly discharged in parallel.
Abstract:
Ozone is generated by directing ambient air through a co-axially oriented cathode and anode. In a preferred embodiment, the outer electrode is a tubular cathode, with the anode disposed about a longitudinal axis therein. The anode is provided with a plurality of vane assemblies, with each individual vane canted at an angle of from about 15null to about 70null, and preferably about 45null, to the planar body of the vane assembly. Air flow is provided either coincident with the longitudinal axis, or tangentially thereto.
Abstract:
The present invention relates to a method for metal coating on a tube, particularly a tube for ozone generators which have been widely used for commercial and industrial purposes. Quartz or high aluminum-oxide-containing is a preferred material for the tube for an ozone generator. According to the present method, the tube is coated with a film of gold by putting the tube in a stove wherein the temperature and baking time is controlled. The present method for coating improves the durability of tubes operated at high temperature brought forth by micro-discharge, and thus extends the service life of the tube as used in an ozone generator.
Abstract:
A household apparatus for treating water has a water treatment reactor; a dispense water path extending from the water treatment reactor to a dispenser whereby treated water produced in the water treatment reactor exits the apparatus by the dispenser; a filter removably mounted in the dispense water path; and, a sensor, (which may be a timer, a flow rate sensor and/or a back pressure sensor) for monitoring the flow of a treated water through the filter, the apparatus issuing a signal advising a user to change the filter when the time for the treated water to flow through the filter exceeds a predetermined value.
Abstract:
A corona-type, air-cooled ozone generator has a cluster of ganged cylindrical generator units (100) packed into a cylindrical pipe (10). Each unit has an inner electrode (101), a dielectric tube around the inner electrode (103), and a concentric outer electrode (102 with side wall openings (112). The corona air gap is between the dielectric and the outer electrode. The inner electrode and dielectric tube are held in each respective outer electrode with silicone end pieces (152, 151). Voltage is put on the inner electrodes while air is blown through the pipe from a blower (30); the air passes through the gaps between the units' ends and circulates through side wall openings, passing over the dielectric tubes and cooling them. Because the dielectric tubes are small, for example 0.25 inches across, they lose heat quickly and do not reach a high temperature. The generator is compact.

Abstract:
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.
