Abstract:
An ozone generating system and an ozone generating method producing ozone at a high concentration and operating at high efficiency, in which a raw material gas with no nitrogen added and mainly containing oxygen is used. The amount of generation of NOX by-product is null. A raw material gas not containing nitrogen and mainly containing oxygen is supplied to an ozone generator, an AC voltage is applied to produce discharge light having a wavelength of 428 nm to 620 nm, a catalytic material containing a photocatalytic material with a band gap energy of 2.0 eV to 2.9 eV is provided on an electrode or a dielectric in a discharge region, gas pressure is kept at 0.1 MPa to 0.4 MPa, and ozone is generated.
Abstract:
The present invention provides a method and apparatus for sterilizing articles using an ozone-containing gas, where condensation of water from the sterilization atmosphere during the sterilization process is substantially prevented. The inventive sterilization method includes providing a sterilization chamber and placing an article into the sterilization chamber. The sterilization chamber is sealed prior to equalizing the temperature of the article and the atmosphere in the sterilization chamber. A vacuum is applied to achieve a preselected vacuum pressure in the sterilization chamber. Once the vacuum pressure is set, water vapour is supplied to the sterilization chamber. Ozone-containing gas is then supplied to the sterilization chamber and the sterilization chamber remains sealed for a preselected treatment period, where the sterilization chamber remains sealed throughout the whole process. Finally, vacuum in the sterilization chamber is released.
Abstract:
Electro-kinetic air transporter and conditioner systems and methods are provided. A system includes a pin emitter electrode and a ring collector electrode located downstream from the emitter electrode. A driver electrode, which is preferably insulated, is located at least partially within an interior of said ring collector electrode. A high voltage source provides a voltage potential to at least one of said emitter electrode and said collector electrode to thereby provide a potential difference therebetween. The driver electrode may or may not be at a same voltage potential as the emitter electrode, but should be at a different voltage potential than the collector electrode. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
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:
An improved ozone generator having at least one dielectric layer between spaced-apart electrodes and having a corona chamber with dielectric solid adsorbent particles disposed in the corona chamber for selectively adsorbing ozone.
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.
