Abstract:
This invention concerns a SiO.sub.2, SiN.sub.x protection film formed by a CVD or PVD gas phase glowing method capable of preventing melting of the matrix ingredients at the surface of a dielectric material in electric discharge of an ozone generator and it relates to a dielectric material used for an ozone generator capable of overcoming the problems for the abrasion of electrode and dielectric material or melting of ions or molecules of during electric discharge, as well as a method of forming a protection film therefor based on the finding that an SiO.sub.2 film or SiN.sub.x film can be formed easily on a surface of a predetermined electric material or, further, on a surface of electrode by processing a specific reaction gas, for example, comprising a crude gas such as SiH.sub.4, SiCl.sub.4, N.sub.2, NH.sub.3 or TEOS or further incorporated with an inert gas or like by means of an atmospheric CVD process such as CVD or heat CVD and, in particular, on the finding that the protection film can be disposed directly to the surface of the dielectric material and the electrode in an ozone generator after the completion of assembling.
Abstract:
In an ozone generator, spring elements (5) of metal pointing transversely to the longitudinal direction of the tube are provided for spacing the dielectric (3) from the metallic outer electrode (1). These spring elements are either bonded directly to the dielectric (3) and are stuck onto a tape-shaped carrier which is attached to the dielectric (3) and at their free ends rest against the inside wall of the outer electrode (1). In this manner, the discharge gap is only minimally constricted and the assembly of the inner tubes (2a, 2b) is simplified.
Abstract:
A self-contained and self-supporting cell for generating ozone by corona discharge which consists basically of two open-ended straight tubes. An inner metal tube serves as a first electrode and is cooled by a fluid flowing through its core. An outer glass or ceramic tube concentrically surrounds and is shorter than the inner tube, carries a second electrode on its outer surface, and is cooled by a flow of fluid across its outer surface. The inner metal tube serves as a supporting column on which all other components are mounted and aligned. It carries a collar near each of its ends, and across each collar are clamped outer end-pieces carrying coolant seals and fittings, the inner side of the clamp assembly comprising flat aligning plates. Short cylinders of non-conductive inert material, bearing seals on each face and dry gas inlet/ozone outlet ports, fit concentrically around the inner tube and are clamped between the surfaces of clamping-plates. The ends of the dielectric tube fit inside sealing rings in the inner faces of the short cylinders. The invention also includes an extension coupling which allows the mounting of two or more dielectric tubes in series on a single metal tube.
Abstract:
A sealed glass tube having an electrical conductor therein arranged when combined with a high voltage and an encircling perforated metal member on the tube to produce ozone. The tube has an electrically conducting cap fitted on and integrally secured to one end thereof, and an externally threaded adapter is mounted on the cap for quick attachment to and detachment from an ozone generator manifold. The conductor has a projecting end secured to an outer end wall of the cap, and such wall in turn has a lug attached thereto providing quick attachment to a source of high voltage.
Abstract:
An ozone-generating element is disclosed which has a tube ozonizer (1), consisting essentially of an outer metal tube (3) forming one electrode, and of a glass tube (4) which is located coaxially therein and is spaced from it and the inner surface of which is provided with an electrically conductive layer (5) serving as the other electrode. Ozone is formed by pulse discharges with a passive, plate-like spark gap (12) with a defined response voltage serving as a switching element. The tube ozonizer (1) is fed by a low-frequency current source (7) via a high-voltage transformer (9), to the secondary winding (10) of which a storage capacitor (11) is connected. A series of embodiments is proposed, and in these part or all the constructional elements of the critical pulse circuit form a constructional unit with, or integrated into, the tube ozonizer (1). In this way, it is possible to produce pulse circuits of extremely low inductance which lead to up to a doubling of the total efficiency of ozone generation. By means of the highest integration stage which is considered especially advantageous, it becomes possible to convert conventional ozone generators fed with alternating current to pulse operation, without having to carry out expensive conversion and adaptation work, especially in terms of circuitry.
Abstract:
A substantially tubular-shaped ozone generator embodying an inner electrode, a coaxial outer electrode surrounding the inner electrode and a tube member formed of dielectric material arranged between the inner electrode and the outer electrode. Within the tube member formed of dielectric material there is arranged a substantially cylindrical core provided at its outer surface with one or a number of substantially helically-shaped grooves extending in the axial direction of the core and forming a throughpass channel for the medium to be ozonized and the ozone which is generated.
Abstract:
Apparatus for the production of ozone is disclosed. The apparatus comprises two or more electrically conductive wires each encased in an insulating material being brought into contact with each other. The principal advantage of the apparatus of the present invention is its durability.
Abstract:
An ozone generator module of the electric 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. Surprisingly good results are obtained by employing a combination of three method steps; - limiting variation in the cross sectional dimension of the field to within a very small range of tolerance; controlling the temperature of the electrodes; and limiting the density of the field by regulating the voltage across the field and the frequency employed.
