Abstract:
An apparatus for generating ozone with at least one ceramic tube forming a dielectric, a discharge electrode associated with the ceramic tube and connected to a high voltage supply and a counter-electrode is proposed, in which the at least one ceramic tube is cooled by a coolant and an oxygen-containing gas is passed into the vicinity of the discharge tube. The at least one ceramic tube (1) is inserted in a ceramic moulding (2) by means of oxidic glass or ceramic solders and an encasing tube (6) embraces the at least one ceramic tube (1) and is sealed against the ceramic mouldings (2).
Abstract:
A multi-tube ozone generator which includes a plurality of ozone generating tubes packed or nested in a close proximity to one another to provide a compact and nested configuration while still providing sufficient cooling passages between the tubes. Each of the tubes is provided with a central portion and an enlarged, flared hexagonal configured end portion which are joined to adjacent flared ends along their mating edges. The present invention also relates to a method for making such an ozone generator.
Abstract:
In an ozone generator of modular design, glass tubes (3) are installed, tightly packed, in a housing (2) and cast therein by a casting compound (4) of good thermal and/or electric conductivity. Double helixes (5) of steel wire are placed in the glass tubes. Only the spaces between the tube inside wall and the steel wires act as discharge spaces (6).
Abstract:
A corona discharge ozonator is provided that comprises a first electrode, a second electrode and a dielectric material disposed between the electrodes. An ozonization chamber is formed between one of the electrodes and the dielectric material and defines a fluid flow path. A plurality of thermally-conducting solids are within the fluid flow path. Substantially each of the solids touches another of the solids and either the dielectric material or the first or second electrode. These solids transfer heat from the hotter to the cooler of the dielectric and the first or second electrode when one of the electrodes is cooled by a conventional means such as a water bath. Corona discharge ozonators of the invention have improved ozone output and increased ozone production energy efficiency.
Abstract:
A method of treating liquid waste with ozone by passing the liquid to be treated between complementary horizontal electrodes having therebetween electrically conductive particles so as to form an electrode bed, pulsing air simultaneously with said liquid, and maintaining between said electrodes an electrical potential so that as the air and liquid pass through said electrode bed, the bed expands to establish electrical contact between the electrodes thus to create localized arcing between particles in the bed and to form ozone.
Abstract:
The invention provides a process for the mass production of ozone in a liquid form from liquid oxygen, by the utilization of ozonizing radiations or electric discharge occurring in the oxygen gasified by being warmed to a temperature not higher than the boiling point of ozone.
Abstract:
A unique combination of one and preferably a pair of gas drying units for drying oxygen containing gas to be ozonized and a corona discharge ozone generating unit is provided by a vortex tube unit having an inlet for receiving dried air to be ozonized, a cool air outlet carrying the slow moving molecules of the gas to the inlet of the ozone generating unit and a warm air outlet connected through passageways extending to openings in the drying units for circulating warm air for drying saturated gas drying units. Where two drying units are provided, the air to be dried and ozonized is preferably alternately automatically fed to the inputs of the two drying units, and the warm air outlet of the vortex tube unit is alternately fed through the air drying unit so the drying unit which at a given instant is not receiving air to be dried is itself being dried by warm de-moisturizing air.
Abstract:
A SILENT OZONIZER IS DISCLOSED WHICH INCLUDES A CYLINDRICAL DIELECTRIC TUBE CARRYING A FIRST ELECTRODE ON ITS INTERIOR BETWEEN ITS ENDS. A HOUSING MEANS INCLUDING A SECOND ELECTRODE IS LOCATED AROUND THE DIELECTRIC TUBE SO AS TO DEFINE A TUBULAR CHANNEL EXTENDING BETWEEN THE TWO ELECTRODES. MEANS ARE PROVIDED FOR INTRODUCING AND REMOVING THE GAS TANGENTIALLY FROM THE OPPOSITE ENDS OF THE CHANNEL. PREFERABLY THE DIELECTRIC TUBE IS A TRANSPARENT TUBE WHICH IS DIRECTLY CONTACTED BY THE FIRST ELECTRODE AND THE SECOND ELECTRODE IS OF A METAL WHICH ACTS AS AND/OR WHICH CARRIES A CATALYST FOR THE PRODUCTION OF OZONE. SUCH A CATALYST MAY BE USED IN A DIFFERENTLY CONSTRUCTED OZONIZER; SIMILARLY SUCH A TRANSPARENT DIELECTRIC TUBE MAY BE UTILIZED BETWEEN ELECTRODES IN OTHER DIFFERENTLY CONSTRUCTED SILENT OZONIZERS.
