摘要:
An ozone generating apparatus comprising at least one ozone generating unit including: two electrodes (2,31) mutually opposed to generate discharge in response to high voltage applied therebetween; at least one dielectric (4) interposed between the electrodes; and a gas supply mechanism to supply an oxygen-containing gas between the electrodes so as to generate ozone by the discharge; wherein a discharge space (5) has a gas pressure of one atmosphere or more. The invention is characterised by a choice of discharge gap length (less than 0.4 or less than 0.6 mm) and by the product of the gas pressure and the discharge gap length.
摘要:
The invention relates to an ozone generator comprising a plurality of hollow cathode tubes which are arranged between the bases of tubes and which define an inner area through which gas flows and an outer jacket area which can be impinged upon by a coolant. A cooling unit comprising an evaporator, a compressor and a condenser is provided for cooling purposes. Efficiency is particularly high by virtue of the fact that the evaporator of the cooling unit is directly integrated into the outer jacket of the ozone generator. Production costs are reduced by virtue of the fact that fewer, more corrosion-resistant materials are used.
摘要:
In an electric discharge type ozonizer using highly pure oxygen gas having a purity of not lower than 99.99% as a raw material gas, the pressure of a gas in the discharge space of a discharger is raised to a level higher than atmospheric pressure by at least 1.1 kgf/cm² and/or in which a liquid-cooled discharger is used, and the temperature of the cooling liquid is set at a level not lower than 15°C, whereby the ozonizer is capable of stably producing ozone gas at a high ozone concentration without causing lowering of the ozone concentration with time.

A corona discharge ozonator (10) is provided that comprises a first electrode (12), a second electrode (14) and a dielectric material (16) disposed between the electrodes. An ozonization chamber (24) is formed between one (14) of the electrodes and the dielectric material (16) and defines a fluidi flow path. A plurality of thermally-conducting solids (40) are within the fluid flow path. Substantially each of the solids touches another of the solids and either the dielectric material (16) or the first or second electrode (12, 14). These solids (40) transfer heat from the hotter (12) to the cooler (14) of the dielectric (16) and the first or second electrode when one (14) of the electrodes is cooled by a conventional means such as a water bath (34). Corona discharge ozonators (10) of the invention have improved ozone output and increased ozone production energy efficiency.
摘要:
An ozone generator is set forth wherein the production of ozone is increased by the more efficient cooling of the generator electrodes and therefore the discharge gap where the ozoneforms. The cooling is effected by the use of a boiling coolant fluid which has a high heat transfer capacity. Additionally the electrode structure is made more rigid for increased life in the presence of boiling cooling fluid. A method of ozone preparation is also set forth. Alternately cooling can be enhanced by the introduction of a gas into the coolant to enhance coolant turbulence without boiling the coolant.
摘要:
This is a discharge cell used for an ozonizer. A space where a discharge gap amount is determined between the first electrodes 10 and 10 is formed by stacking a couple of upper and lower first electrodes 10 and 10, constituted by the plate-like rigid body, in both sides with sandwiching a couple of rigid body spacers 20 and 20. In this space, a dielectric body unit 30 that consists of a rigid body of the sandwich structure of sandwiching a second electrode 32 is arranged between glass plates 31 and 31. The dielectric body unit 30 is supported in a neutral position in the space by a plurality of spacers 40, 40,... for discharge gap formation that are inserted between the upper and lower first electrodes 10, and forms discharge gaps 50 and 50 in both sides. The minimum discharge gap amount G of 0.4 mm or less is stably secured. It is possible to prevent the damage of a cell component and a pressurizing mechanism.

An ozone generating apparatus comprises at least one ozone generating unit which includes: two electrodes mutually (2, 31) which are opposed to generate a discharge in response to high voltage applied therebetween; at least one dielectric (4) interposed between the electrodes to provide insulation between the electrodes; and a gas supply mechanism to supply an oxygen-containing gas between the electrodes so as to generate ozone by the discharge. In this unit a spacer (61) is inserted into a discharge space (5) causing the discharge to ensure a predetermined distance or more between the electrodes of the ozone generating unit, and the spacer forms a non-discharge portion where no discharge occurs.
摘要:
An ozonizer, wherein plate-shaped electric discharge cells are prevented from being deformed, and, even when ozone gas of high concentration and high pressure is produced, an outstanding ozone generation efficiency can be secured. The main body (10) of the ozonizer formed by stacking a plurality of electric discharge cells (11) is housed in a pressure vessel (20). Pressurized gas having a pressure equal to the pressure of material gas supplied to the electric discharge cells (11) is supplied to the pressure vessel (20). The difference between the interior and the exterior of an electric discharge cell (11) is eliminated, so that the deformation of an electric discharge cell (11) is prevented. Dry gas is used as the pressurized gas, whereby the insulation failure due to condensation can be avoided.
