Abstract:
A frame-type ozone generator (242) has a plurality of elongated electrodes (201, 202) deployed in substantially parallel, spaced relation to each other so as to form a substantially flat electrode array, and a flow generator (241) for generating a flow of oxygen containing gas through the electrode array in a direction substantially perpendicular to the electrode array. Each of the electrodes is formed from an electrically conductive core (211) covered with polyvinyl-difluoride (212). Preferably, each electrode array is arranged within a frame (206) of a given area. Also disclosed are an apparatus for treating a product with ozone-containing gas in which pressure-waves are used to enhance effectiveness of the ozone treatment, and a two-chamber batch method for implementing treatment of a product with possibly harmful gases such as ozone.

Each of the electrodes is formed from an electrically conductive core covered with polyvinyl-difluoride. Preferably, each electrode array is arranged within a frame of a given area, each frame being configured for assembly with other similar frames to form an extended ozone generator of area greater than the given area. Also disclosed are an apparatus for treating a product with ozone-containing gas in which pressure-waves are used to enhance effectiveness of the ozone treatment, and a two-chamber batch method for implementing treatment of a product with possibly harmful gases such as ozone.

The gas flow rate adjustment apparatus (7) includes a plurality of flow rate adjustment parts (71, 72, 73, 75), and outputs a second mixed gas serving as the raw material gas to the ozone generation apparatus (1). The second mixed gas includes an oxygen gas outputted from a first oxygen flow rate adjustment part (71) and a first mixed gas outputted from a mixed gas flow rate adjustment part (75). The raw material gas generated by the gas flow rate adjustment apparatus (7), which includes an oxygen gas and a nitrogen gas, contains the nitrogen gas added to the oxygen gas with the rate of addition being in a range of more than 0 PPM and not more than 100 PPM.

Abstract:
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.
Abstract:
A method is proposed for generating a non-thermal plasma having a predetermined ozone concentration, with the following steps: providing an at least approximately closed volume as a reaction region (5); activating a plasma source (3) and generating a non-thermal plasma in the reaction region (5), wherein the plasma is held in the reaction region (5) at least until a predetermined ozone concentration is reached or the ozone concentration falls below a predetermined upper limit.
