Abstract:
An ozone generator for generating ozone by applying a specified process to oxygen by discharge includes a first raw material gas supply unit for supplying the oxygen as a first raw material gas, and a second raw material gas supply unit for supplying an oxide compound gas as a second raw material gas, in which, by excited light, excited and generated by a discharge in the oxygen and the oxide compound gas, the oxide compound gas is dissociated, or the oxide compound gas is excited accelerating dissociation of the oxygen, and ozone is generated. In this way, ozone generation efficiency is raised.
Abstract:
A method and apparatus for improving the yield of ozone gas in a closed ozone generator unit. In a closed ozone generator unit, oxygen gas is transformed into ozone gas by means of alternating current, the oxygen gas being substantially pressurized before entry into the unit. The unit is exposed to an external pressure substantially equal to or higher than the pressure of the oxygen gas.
Abstract:
The present invention discloses an ozone generator with reduced NOx comprising an air stream generating device; a drying device; an electrical field generating unit; a high-voltage generating device; and a cooling device. The flow velocity of the air stream in the ozone generating area can be increased by the air stream generating device up to 700 s.c.c.m. The temperature in the ozone generating area can be lowered by the cooling system to lower than 10° C. The amount of NOx produced by the disclosed ozone generator can be reduced substantially.
Abstract:
An electronic type ozone generating device utilizing an elongated tube or cylinder having a negative electrode in the form of a fine wire, and a conductive coating on an inner surface of the tube connected to a source of positive potential, whereby air to be ionized forms a dilectric. In contrast to prior art devices in which the air to be treated flows in substantially continuous fashion, means is provided for injecting fixed quantities of air to be treated in pulsed fashion to provide for greater effectiveness. In a second embodiment, means is provided for moving a plurality of fine wire electrodes in an orbital path within the tube relative to the principal axis thereof to provide greater ionization.
Abstract:
A method for ozonation of a water stream by providing at least 70% by volume oxygen feed gas, generating 4-8% by wt. ozone in such gas by silent electric discharge with low power per unit ozone, contacting with water to dissolve ozone, and atmospherically venting ozone-depleted gas from the contacting.
Abstract:
A three phase power ozonator system in which the head of an ozonator cell containing multiple cylindrical type elements is tri-partitioned to define three sectors in the cell each of which contains a portion of the total number of cylindrical type dielectric elements. The partitions are made of insulating material such as polyvinyl chloride. Each sector is distinct and each sector is adapted to be operated with single phase electrical power. As a result the ozonator cell as a whole is able to operate using three phase electrical power. This arrangement allows for the operation of the ozonator cell in a system having any number of other three phase electrically operated components of equal or smaller electrical load than the ozonator cell in such a way that a balanced electrical load is maintained throughout the system.An electrical supply and control sub-system including a three phase power transformer, current sensors for each electrical sector and voltage sensor for one sector, current and voltage comparators and a variable transformer driven by a reversible electric motor, provides current to the electrodes in all sectors, monitors the current in all phases and turns off the electrical supply if significant imbalances among the sectors are detected.
Abstract:
A PERIODICALLY REVERSE GAS FLOW METHOD AND APPARTUS FOR OZONE PRODUCTION IS DESCRIBED. BECAUSE MOISTURE REDUCES THE EFFICIENCY OF MOST OZONIZERS, MOISTURE REMOVED FROM AN OXYGEN CONTAINING FLUID BEFORE IT PASSES THROUGH THE OZONOIZER AND THE MOISTURE IN RETURNED TO THE OXYGEN AND OZONE CONTAINING FLUID AFTER THE OZONIZER. AT LEAST TWO MOISTURE ADSORBENT MATERIAL COLUMNS ARE USED SO THAT THE OXYGEN CONTAINING FLUID IS FIRST PASSED SERIALLY THROUGH THE TWO COOLUMS WITH THE OZONIER INTER POSED AND THEN PERIODICALLY REVERSED TO PASS SERIALLY THROUGH THE THREE COMPONETS IN THE OPPOSITE DIRECTION SO THAT AT LEAST ONE COLUMN IS ALWAYS IN AN ADSORBENT CYCLE WHILE AT LEAST ANOTHER COLUMN IS ALWAYS IN A DESORBER CYCLE. THE PRESSURE OF THE OXYGEN CONTAINING FLUID MAY BE INCREASED IMMEDIATELY UPSTREAM OF THE ADSORBER COLUMN AND REDUCED IMMEDIATELY DOWNSTREAM OF THE ADSORBER COLUMN, FOR INCREASED EFFICIENCY. THE HEAT OF ADSORPTION IS TRANSFERRED FROM THE ADSORGER COLUMN TO THE DESORBER COLUMN, WITH THE OZONIZER SERIALLY INTERPOSED; THE COOLANT FLUID FLOW IS PREFFERABLY CO-CURRENT TO THE OXYGEN FLUID FLOW AND REVERSED EVERYTIME THAT THE OXYGEN CONTAINING FLUID FLOW IS REVERSED.
