Abstract:
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.
Abstract:
In an ozone generator composed of a plurality of circular, plate-shaped high-voltage electrodes arranged in a stack, the electrodes including at least two solid electrodes which are spaced from one another and a counter-electrode, the generator further being composed of two circular plates of insulating material disposed in the stack between the two solid electrodes, with the counter-electrode being disposed between, and spaced from, the two plates to form therewith two discharge spaces, and with the outer diameter of the counter-electrodes being less than that of the plates, and a ring clamped and squeezed between the plates in the vicinity of their peripheries, the ring is of a gasket material which is initially resilient, and which is formed to have, at each side directed toward a respective plate, at least two beads projecting in the axial direction of the plates and spaced apart in the radial direction of the plates, and the plates are rigidly supported against the two solid electrodes.
Abstract:
An ozone generator of simplified construction comprising a tubular first metallic electrode surrounded by a concentric tubular dielectric member having on its outer surface a second metallic electrode, the dielectric member being longer than the first electrode, and identical end members for slidably receiving and mounting the first electrode and the dielectric member to form an ozone generator, whereby compressive forces are borne by the first metallic electrode.
Abstract:
An ozone generator having a housing accommodating parallel mounted ozonizing elements, each consisting of water-cooled inner and outer electrodes mounted coaxially with a constant gap through which passes the gas to be treated and in which an electric discharge is initiated. Located between the ozonizing elements along their axes are cooling chambers communicating with the gaps of the adjacent ozonizing elements. The inlet and outlet devices for passing the gas to be treated are so arranged in the housing that the gas passes through the ozonizing elements in a direction across their axes.
Abstract:
An ozone generator module of the electirc discharge field type is provided having at least one cell comprising an assembly of three concentric tubular members, the inner and outer tubular members being electrodes separated by a tubular dielectric member spaced from one of the electrodes a distance sufficient to define a high density electric discharge zone between them, the cell or cells being disposed within a liquid container. Substantially optimum conditions for the production of ozone are provided by making the cross sectional dimension of the field uniform throughout to within a very small range of tolerance and by controlling the temperature of the electrodes by cooling them with liquid coolants one of which is a dielectric liquid, and limiting the density of the field by regulating the voltage across the field and the frequency employed.
