Abstract: An apparatus for purifying air comprising two electrodes having a dielectric material such as glass extending therebetween. The dielectric material is air permeable, for example, in the form of a bed of discrete particles such as glass beads. The electrodes are also air permeable, allowing the air to flow through the electrodes and dielectric. Ozone is generated by discharge at points of contact of the dielectric particles. Airflow through the device is improved, allowing greater cooling, and higher volumes of airflow but at lower concentrations of ozone production than with prior art devices, thus reducing toxicity.

Abstract: An apparatus for generating ozone and other atoms and molecules resulting from the bombardment of a feed gas with electrons has, preferably, a first electrode positioned within a channel in a second electrode. The first electrode is a substantially sealed tube made of dielectric material, having at least one electron gun positioned proximate an end thereof for firing electrons into the first electrode. In electrical communication with the electron gun is a rod, maintained in a tube also made of dielectric material, which acts to maintain a constant energy level through the length of the rod and thus the length of the electrode. Within the first electrode is an inert gas which, upon the firing of the electron gun, is formed into a plasma. When a feed gas (generally air) is passed between the first and second electrodes, the electrons and plasma cause the formation of ozone and other atoms and molecules in the feed gas, which products have beneficial uses in the treatment of water and air for different purposes.

The ozone generator in the system comprising a pair of conductive plates mounted parallel and opposed to each other and a pair of dielectric films. Preferably fused quartz, adhesively secured to the opposed faces of the plates by a heat-conductive, electrically-conductive adhesive.

Abstract: In order to enhance the efficiency of an ozone generator it is proposed that its outer electrodes (1,2) are formed essentially as metal plates arranged and separated from one another in pairs, between which a tube (3) or a layer of closely-spaced tubes (3) with a diameter corresponding to the separation of the metal plates lies. The tubes (3) have an outer coating of dielectric material, or themselves consist of such, and possess in each case an inner electrode (4) of an electrically conductive material.Despite a comparatively inhomogeneous discharge gap (6), such an ozone generator has a high efficiency of ozone generation because the heat arising in the discharge space can be dissipated optimally.
