    Abstract: An ozone generator includes at least four independent ozone generation control channels that energize at least four independent ozone generation plates. The at least four independent ozone generation control channels allow for multiple modes of operation, including sterilization, disinfecting, and managing, in addition to interleaved operation, which significantly extends the useful life of the individual ozone generation plates. The ozone generator is placed in a preexisting conditioned airflow that enters a conditioned airspace enclosed by a container. Being placed in the preexisting conditioned airflow, the ozone generator does not require a fan or other air movement device to actively transport ozone-enriched air or oxygen through the ozone generator.

  • Patent number: 8734727
    Abstract: Apparatus for the production of a product gas (eg hydrogen and ozone) comprises: a supply of reactant gas (eg oxygen and steam) (14); a pair of electrodes (24) with a space between them of less than 1 mm (28); a conduit to lead the reactant gas from the source through the space between the electrodes; a power source (26) to apply a voltage across the electrodes to dissociate the reactant gas and ultimately permit formation of product gas; and a conduit (40) to supply the product gas to an outlet. A sterilization unit for water treatment employs such apparatus and includes a fluidic oscillator to oscillate the flow of oxygen and/or ozone, and wherein said outlet comprises a plurality of orifices (42) to be submerged in said water and for the purpose of forming micro bubbles of ozone. An analyzer for detecting large organic molecules in eg air can employ the ozone generator to breakdown the large molecule into simpler and easier-to-detect-and-identify molecules.

  • Patent number: 8733596
    Abstract: A method of generating ozone containing fluid comprising: drawing atmospheric air into an air compartment, generating ozone within the air compartment from air in the air compartment by conversion within the compartment of oxygen in the air within the compartment into ozone to form ozonated air, discharging the ozonated air from the air compartment, mixing the ozonated discharged air with a flowable fluid to form a ozonated fluid-air mixture, and passing the ozonated fluid-air mixture out a discharge outlet. Preferrably the method is carried out in a dispenser utilizing a piston pump to draw air through a corona discharge ozone generator and to draw liquid from a liquid reservoir and simultaneously pass both the ozonated air and liquid through a foam generator to generate foam.

  • Patent number: 8728402
    Abstract: The invention relates to an ozone generator, comprising two electrodes and a dielectric layer arranged between the above such that between the dialectic layer and one of the electrodes an ozonizing gap is formed, through which an oxygen-containing gas can be run. In the direction of the flow of the gas, a dielectric capacity (CD) of the dielectric layer of the gas becomes smaller and/or layer thickness of the dielectric layer becomes greater, such that a gap width of the ozonizing gap is greater on the inlet side than the outlet side.

    Abstract: An apparatus for generating ozone inside packaged articles comprises an electrode assembly in which coplanar electrodes are supported along a contact surface. The electrodes are solid state conductive electrodes. These electrodes may be interdigitated and/or arranged with uniform spacing therebetween along a portion of their length. Where the electrodes are straight they may be parallel, but other shapes can also be evenly spaced. In some examples the electrodes are partially insulated and partially exposed. In some examples the electrodes are embedded/potted in an insulator to exclude air spaces from around the electrodes.

    Abstract: A method and apparatus for combustion analysing a sample in a combustion analyzer (120,160,180), where the sample comprises a proportion of sulphur. The sample is supplied to the combustion analyzer and combusted to produce combustion products, comprising a yield of sulphur dioxide for detection. Nitrogen monoxide or a source of nitrogen monoxide is supplied to the combustion analyzer to improve the yield of sulphur dioxide in the combustion products. The yield improver may be supplied before and/or during the combusting step. A proportion of yield improver is preferably greater than the (expected) proportion of sulphur. Ozone may be supplied to the combustion products to convert at least a proportion of any nitrogen monoxide in the combustion products to nitrogen dioxide, before detection.

  • Patent number: 8696796
    Abstract: Systems and methods for producing an ozone destructor are disclosed herein. Generally, these systems and methods include an ozone destructor that has a housing defining an air passage duct. In some cases, this air passage duct includes a first chamber and a second chamber that are arranged so that air is able to flow into the first chamber, through the second chamber, and out of the destructor. In some cases, an air drying mechanism is disposed in the first and/or the second chamber. Additionally, in some cases, the ozone destructor further includes multiple mechanisms that reduce ozone to oxygen. In light of these features, the ozone destructor is capable of incrementally drying and reducing air and ozone, respectively, as they pass through the first chamber and the second chamber.
