Abstract:
An ozone production apparatus for increasing ozone generation efficiency by improving ceramic plate cooling efficiency. An ozonizer of this invention has a steel plate shaped body for use as a discharge electrode through which gas is permeable from one surface to another. This discharge electrode is faced on both sides by two ceramic plates, with a material gas flow inlet provided on one side and an ozone flow outlet on the other side. The ozonizer unit is provided with an insulated waterproof cable for applying a high voltage to the discharge electrode. This ozonizer unit is submerged inside a cooling water tank, and a high voltage, high frequency power supply unit is connected between the discharge electrode and the cooling water, with the cooling water tank as the grounded side. In this manner, since the ozonizer unit is submerged inside the cooling water tank, the cooling efficiency is improved and the ozone generation increased.
Abstract:
An ozone generator (10) has top and bottom chambers (12, 14) interconnected by a vertically extending elongated tubular assembly (16). Assembly (16) has a control electrode (18) within a conductive tube member (20) and separated therefrom by an annular dielectric member (22) which only partly fills the space between items (18, 20). The dielectric member (22) is suspended by an O-ring at its upper end within the top chamber (12) and is free from contact with both the electrode (18) and the tube member (20). Gas flow between the top and bottom chambers (12, 14) is along radially inner and outer annular passageways within the assembly (16) and the top chamber (12) is partitioned into two chambers which respectively communicate with these passageways. The generator (10) may have a plurality of similar assemblies (16) extending in parallel between common top and bottom chambers (12, 14).
Abstract:
An ozone generator for producing ozone at pressures of up to 10,000 psi from oxygen or oxygen containing gas, which contains two electrodes for forming a corona discharge through the input gas, the first electrode being cooled by a first cooling fluid and the second electrode being cooled by a second cooling fluid, which further contains flexible barrier means for equalizing the pressure between the cooling fluids and the input gas.
Abstract:
An ozone generator utilizes one or more cylindrical anodes having disposed centrally therein an elongated cylindrical dielectric tube. The dielectric tube is filled with an inert gas at low pressure and contains at a first end thereof beyond the encirclement of the anode a relatively short electrode. In a preferred embodiment, the electrode takes the shape of a cone having the small end thereof coupled through the first end of the dielectric envelope to a source of high energy alternating electric power. The large end of the cone is open and directed toward the far end of the dielectric envelope. Electrons are emitted from the electrode and focused down the length of the dielectric envelope, creating an electron haze which induces a variety of electron focusing phenomena in an annular reaction space between the dielectric envelope and the encircling anode. These electron focusing phenomena include a corona on the outside of the dielectric envelope, high voltage spikes between the dielectric envelope and anode, and a virtual plasma filling the annular reaction space. The electron focusing phenomena induce ozone formation when oxygen bearing feed gas is pumped down the length of the reaction space. The exterior of the anode is provided with a water jacket for heat removal. Use of the ozone generator in a water purification system is disclosed for illustrative purposes.

An ozone generator cell of a novel design includes a thin ceramic sheet sandwiched between a perforated metallic sheet serving as discharge electrode and a water-cooled aluminum base. Dry air or oxygen is passed over the electrode surface and a high-voltage, high-frequency electric field is applied between the electrode and the base for a corona discharge.
Abstract:
A corona reaction system of the type wherein substantially all of the heat generated by corona discharge is removed from the system by gas flow therethrough. A corona discharge gas flow path is provided which is between 2.0 and 10 inches in length and bounded by discharge electrodes spaced apart at a distance of between 0.01 and 0.250 inch, whereby low pressure drop over the gas flow path is maintained under conditions of high power density and gas temperature.
Abstract:
A housing has an interior casing receiving a coolant. This casing is associated with a forced cooling system and has open ended tubular portions therethrough formed of electrically conducting metal. Glass ozone generating tubes are removably supported in the tubular portions by axial movement and are held in spaced ozone generating position by spacers on the tubes. The tubes have an electrically conducting silver coating on the interior surface and have an interior band engageable with the coating for admitting high voltage to the tube from a conductor leading into the tube. A treatment tank associated with the ozone generating system has a recirculating conduit operably connected with the housing for the ozone generating tubes. An additional conduit extends from the treatment tank to a storage tank and a filter for filtering out coagulated material is provided in this conduit.
Abstract:
High frequency tubular ozonizer in which one common housing contains several ozonizing elements, each of these elements having a high voltage and a low voltage electrode, both embodied in the form of coaxially disposed pipes coated with a dielectric material on the side of the reaction zone and provided with a circulation cooling liquid. Cooling efficiency is increased by providing a core fitted in the expanded portion of each of the high voltage electrodes, whereas each low voltage electrode is made of two coaxially arranged pipes with the cooling liquid circulating between the pipes. The ends of the high voltage tubular electrodes of the ozonizing elements are secured in the walls of manifolds which serve as admitting and discharging conduits for the cooling liquid. The ozonizer of the invention exhibits increased output of 50-100 times and when so constructed drastically reduces capital investment.

A system for subjecting gas to high voltage corona wherein a gas is sequentially (serially) exposed to a plurality of corona generation zones. In a preferred system, the gas is conducted through several corona generators which are connected in series by gas conduits, and the gas within the system is cooled subsequent to each exposure to corona.
