Abstract:
An ozone generating apparatus has a plurality of ozone generating units connected in series to form a plurality of stages along the flow path of a gas. Each ozone generating unit has an ozonizing chamber having a material gas inlet and a product gas outlet and ozonizer discharge electrodes disposed in the ozonizing chamber and connected to an AC high-voltage source. The voltage applied to said ozonizing discharge electrodes of each successive stages is so varied that the ozonizing discharge electrodes of each downstream stage, as viewed in the direction of flow of the gas, is supplied with a lower voltage than the voltage supplied to said ozonizer discharge electrodes of an adjacent upstream stage. A series connection of a plurality of ozone generating units can form a composite ozone generating unit, and a plurality of such composite units may be connected in series to form a plurality of stages. The voltages applied to such successive stages is varied in the same manner a above. The ozone generating unit and the AC high-voltage source can have modular construction.
Abstract:
An apparatus for producing ozone from oxygen includes at least one discharge electrode and counterelectrode which are separated by a dielectric of high heat conductivity and tightly bear on the dielectric that is cooled in a direct manner. The discharge electrode, around which oxygen flows, forms a non-closed surface and is in the form of a wire. By applying an electric field, the discharge electrode triggers a discharge in the gas space surrounding the discharge electrode and on the dielectric. The discharge electrode is made of molybdenum, tungsten, niobium or tantalum and is directly exposed to the oxygen flow.

An ozone generating method for increasing the quantity of ozone produced by a silent discharge in high purity oxygen includes mixing nitrogen with the high purity oxygen in a predetermined ratio. The nitrogen gas is a catalyst for stable and highly efficient ozone generation from a high purity oxygen source.
Abstract:
A tubular type ozone generator with inner and outer concentric electrodes and a middle dielectric member. One end is sealed to permit feed gas traversing the inner gap between the inner electrode and the dielectric member to reverse direction and to traverse the outer gap between the dielectric member and the outer electrode. A method for producing ozone using a tubular type ozone generator where first the total feed gas is passed in one direction between an electrode and the dielectric member for producing ozone, reversed, and then passed in the reverse direction between the dielectric member and the other electrode producing additional ozone. A hollow inner electrode permits more efficient cooling of the inner electrode. A plurality of ozone generators are combined with intake and output manifolds for the feed gas and produced ozone.
Abstract:
A concentric tube ozonator which is designed from theoretical considerations to produce ozone efficiently with minimum electrical power consumption. Concentric tube assemblies in the ozonator are designed for ease of construction and replacement of the components thereof, with each concentric tube assembly providing for the relatively precise positioning of the components therein as is required for proper and efficient operation of the ozonator. Each concentric tube assembly is constructed with an outer tubular metal electrode and an inner tubular metal electrode positioned concentrically within the outer tubular electrode. A glass dielectric tube is positioned concentrically and centrally between the outer and inner tubular electrodes. This construction provides an inner concentric annular electrical field discharge gap between the glass dielectric tube and the inner tubular electrode, and an outer concentric annular electric discharge gap between the glass dielectric tube and the outer tubular electrode, in which the feed gas is converted into ozone. The efficiency of the ozonator is optimized by constructing the ozonator such that the inner and outer annular discharge gaps are maintained in the range of 0.45 mm to 0.55 mm, preferably at 0.5 mm, to provide a minimum discharge gap to convert oxygen to ozone to minimize the voltages required during operation thereof.
Abstract:
Ozone is added to captured water by a method and apparatus which involves corona discharge into an oxygen-containing gas in regions in a generator which alternate with regions where the newly formed ozone is cooled. The alternating corona and cooling regions permit the ozone to form without being thermally decomposed as soon as it is formed. Also disclosed is an overall system and method of controlling the level of dissolved ozone in a body of captured water which modulates the output of an ozone generator in accordance with readings of oxidation-reduction potential in the water.
Abstract:
A device for enriching a fluid with ozone includes an inner tubular member arranged within an outer tubular member and defining a separate flow path for a fluid within the inner tubular member and another one for a fluid between the inner and outer tubular members. An electrode which has a high voltage regulation and a coil portion which extends through the inner tubular member forms a grounding electrode. A fluid such as air which is to be enriched with ozone is passed either through the inner tubular member or the space between the two tubular members and a cooling fluid is passed in the other tubular member. The inner tubular member is made of an ultraviolet penetrable and heat resistant material such as quartz glass.
