Abstract: An ozone producing apparatus includes an ozone generator for generating ozonized oxygen, an adsorption/desorption tower for adsorbing and storing ozone from the ozonized oxygen, and an ozone desorbing device for desorbing adsorbed and stored ozone for supply, wherein the apparatus further includes an oxygen gas supply tank for supplying oxygen to the adsorption/desorption tower at the time that desorption is started and an oxygen gas flow rate adjusting valve for adjusting flow rate of the oxygen gas to, be supplied. Ozone injection can be made definite, and the apparatus is economical in the aspect of both initial and running costs. It presents great effects of preventing slime adhesion and can also limit generation of oxidants even when applied to sea water.
Abstract: An ozonizer and water purifier equipped with the ozonizer comprising an ozonizing discharge element; an electric circuit for applying a voltage to the ozonizing discharge element so as to produce an ozone-generating discharge; a housing having an opening formed therein for receiving the ozonizing discharge element; a cover which seals the ozonizing discharge element in the housing; and a device for turning off the voltage applied to the ozonizing discharge element when the cover is removed. In another embodiment, at least a part of the cover or housing is transparent so as to enable detection of the discharge state of the ozonizing discharge element.
Abstract: A device for supporting instruments in an enclosure, in particular a decontamination enclosure, the enclosure being defined by a bottom, at least one vertical side wall, and a top cover, each instrument having an active portion and a connection portion in the form of a cable, the device comprising a bracket extending substantially perpendicularly to the vertical side wall inside the top portion of the enclosure, said bracket having a plurality of suspension members each of which is designed to co-operate with a portion of cable close to the active portion of an instrument.
Abstract: An electrical apparatus includes a reaction chamber. A stream of contaminated gasses flows through the chamber. An elongated coronating electrode is positioned in the reaction chamber for producing a corona discharge within the chamber. A multi-stage Fitch generator connected to the electrode produces a high level, rapidly pulsating voltage in the electrode. Controlled amounts of an inert gas or inert gas-air mixture are combined with the contaminated gases to provide a high concentration of inert gas in the reaction chamber. In the inert gas-enriched atmosphere, the pulsating corona discharge produces a high concentration of metastable intermediates that greatly increase the rate of chemical conversion of the contaminants. Switching circuitry allows the pulsating voltage output of the Fitch generator to be superimposed on a constant direct current voltage in the electrode, setting up an electrostatic field in the reaction chamber for removing conversion byproducts from the gas stream.

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.
Abstract: An ozone producing apparatus comprising an ozone generator for generating ozonized oxygen, an adsorption/desorption tower for adsorbing and storing ozone from the ozonized oxygen generated by the ozone generator, and an ozone desorbing means for desorbing the adsorbed and stored ozone for supply, wherein a reducer storage for storing reducer therein is connected to the adsorption/desorption tower through a switch valve which is opened when the ozone producing apparatus is under an abnormal driving condition. Desorbed ozone can be safely treated even in the case of power failure or an abnormal driving condition in which high pressure or high temperature exists in the adsorption/desorption tower.
Abstract: An apparatus for producing ozone from oxygen comprises a high voltage electrode connectable to a current source; a ground electrode spaced from the high voltage electrode and having an upstream end and a downstream end; a dielectric element positioned between the high voltage electrode and the ground electrode; a path for air flow positioned between the dielectric element and the ground electrode; and, a current collector positioned downstream of the high voltage electrode and comprising an extension of the ground electrode.
