Abstract:
In the present invention, particularly, means for removing moisture contained in a raw material gas is provided in a raw material gas supply part so that the amount of moisture contained in the raw material gas that is supplied to an ozone gas supply system is reduced, and additionally an ozone gas output flow rate management unit is provided that is configured to receive a plurality of ozone gas outputs from a plurality of nitrogen-free ozone generation units and capable of performing an ozone gas output flow rate control for selectively outputting one or a combination of two or more of the plurality of ozone gas outputs to any of a plurality of ozone treatment apparatuses by performing an opening/closing operation on a plurality of ozone gas control valves provided in the ozone gas output flow rate management unit.
Abstract:
Improvements in the supply of high-frequency electrical power to ozone-producing cells can be accomplished using the systems and techniques described herein. Application of a DC-DC converter operating at a switching frequency substantially greater than a load frequency, supports generation of a high-voltage AC for powering such cells, while allowing for reductions in component size and reductions in a quality factor of a load tuning circuit. Controllable power inverters used in obtaining one or more of the switching and load frequencies can be controlled using feedback techniques to provide stable, high-quality power to ozone-producing cells under variations in one or more of externally supplied power and load conditions. An inrush protection circuit can also be provided to selectively introduce a current-limiting resistance until an input DC bus has been sufficiently initialized as determined by measurements obtained from the DC bus. The current limiting resistance can be a positive-temperature coefficient thermistor.
Abstract:
The invention provides a power supply apparatus for supplying electric power to a capacitive load. The apparatus has a transformer, a positive half-period driver and a negative half-period driver supplying positive and negative half-periods of voltage to the first coil. The second coil forms an electric resonance circuit and supplies electric voltage to the load. Zero crossings of the voltage supplied to the first coil are determined from a third coil on the transformer, and alternation between positive and negative half-periods of voltage supplied to the first coil is done at the zero crossings of the voltage supplied to the first coil.

Abstract:
Devices for generating and storing ozone. A device for generating ozone includes: at least one elongated electrode unit including an outer tubular dielectric member and an inner conducting member having a longitudinal axis; and one or more elongated electrode tubes disposed circumferentially about the longitudinal axis. Each of the electrode tubes is arranged in parallel to the electrode unit. When an electrical potential is applied across the conducting member and electrode tubes during operation, plasma is established between the dielectric member and electrode tubes. The plasma converts oxygen gas into ozone gas.
