    Abstract: This invention relates to apparatus for maximising ozone generation from a UV bulb. The apparatus includes a UV bulb which emits UV light below 200 nm, peaking at 185 nm. Bulbs emitting UV light at 185 nm are well known to generate ozone but generally also emit UV light at 254 nm which is well known to deplete ozone. The concept of the present invention is to create an environment where air or oxygen carrying gas can be exposed to the 185 nm and 254 nm UV light outputs from a bulb in such a way that the 185 nm ozone generating effect is enhanced and 254 nm ozone depleting effect is reduced. The apparatus also includes a member which may either be transmissive to or non-transmissive to UV light at 254 nm and the environment in which the effect of the UV light at 185 nm is enhanced exists between the UV lamp and the member.

  • Patent number: 7560080
    Abstract: A method for generating ozone from gases containing oxygen. The ozone is generated by silent electric discharge in an installation comprising at least two gaps, which are traversed by the gas, each of said gaps being formed between an electrode and a dielectric that separates each gap from an additional electrode. According to the invention, the restriction of the volumetric flow of the gas of at least one gap is controlled.

  • Publication number: 20080193343
    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.

  • Publication number: 20080063578
    Abstract: A system for reducing carbonaceous material is disclosed. The system includes a compartment configured to receive the carbonaceous material. An auger is located within the compartment and centered about a drive shaft. A rotational drive mechanism is coupled to the drive shaft and configured to rotate the auger to enable the carbonaceous material to travel through the compartment as the auger is rotated. A plurality of lifting arms are coupled to a surface of the auger. The lifting arms are configured to lift and stir the carbonaceous material as the auger is rotated. At least one microwave generator is coupled to the compartment and configured to radiate the carbonaceous material as it travels through the compartment to reduce the carbonaceous material into at least one chemical component of the carbonaceous material.

  • Patent number: 7314600
    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.

  • Patent number: 7241428
    Abstract: A compact capacitively coupled electrode structure for use in a gas plasma reactor/generator is disclosed. The electrode structure comprises a parallel plate type anode and cathode spaced to define a gas flow path or volume therebetween. A plurality of electrically conductive fin elements are interposed in the space between the anode and cathode. The fin elements substantially increase the ratio of electrode surface area to volume, and subdivide the gas flow path or volume, thereby substantially increasing the efficiency of plasma gas processing that is possible over a broad range of operating parameters, without substantially increasing the spacing between the anode and cathode. Static or closed operation is also disclosed. Also disclosed is a multi-anode/multi-cathode electrode assembly embodying the basic electrode structure and a highly efficient and compact gas plasma reactor/generator employing the assembly.

  • Patent number: 7179432
    Abstract: An improved corona generator structure includes a ground tube body sheathed within an insulating sleeve. One end of the ground tube body is provided with a sealing lid for being firmly coupled to the end portion of the ground tube body. At least one piece of high voltage electrode plate is coupled with the insulating sleeve. The high voltage electrode plate is provided with a plurality of spacers for allowing a gap of a substantially equal height to be formed between every area of the high voltage electrode plate and the insulating sleeve so as to uniformly distribute the corona on the high voltage electrode plate when electricity conducts therethrough. Furthermore, the two retaining sleeves are coupled to both end portions of the high voltage electrode plate and the insulating sleeve such that the high voltage electrode plate is firmly positioned on the insulating sleeve.
