OZONE GENERATION METHOD AND APPARATUS Russian patent published in 2004 - IPC

FIELD: method and equipment for generating of ozone, may be used for disinfecting of sweet water and purifying of sewage water, as well as for cleaning of air in rooms.

SUBSTANCE: method involves purifying oxygen-containing working gas; separating moisture and directing into gap between electrodes, from peripheral to central parts of electrodes; exposing to electric discharge; creating heat-carrier flow in electrodes, said heat-carrier flow being preliminarily cooled and directed toward flow of oxygen-containing working gas flow, from canter to peripheral parts of electrodes. Apparatus has earthed electrodes located in hermetically sealed casing and adapted to be cooled by heat-carrier. Outer surfaces of electrodes are coated with dielectric material. Apparatus is further equipped with power source, whose terminals are connected to electrodes, connecting pipes for supplying of oxygen-containing working gas and heat-carrier, connecting pipes for discharge of heat-carrier and gas-ozone mixture. Electrodes are made from plates connected in sealing relation along their edges so as to define inner cavity, where jumpers are fixed. Electrode plates are made flat, arranged in parallel with one another and rigidly connected through jumpers positioned perpendicular to electrode plate surfaces. Maximal distance between jumpers is determined by ratio: where B is jumper gap, m; δ is thickness of plates, m; ς_t is admissible mechanical tension of plate, Pa; ΔP is pressure difference between electrode cavity and discharge gap, Pa. Connecting pipes for supplying of heat-carrier to electrodes and discharge of heat-carrier from electrodes are communicated with cavity of electrodes through injectors and collectors made in the form of pipes with openings arranged at opposite edges of electrodes.

EFFECT: increased efficiency in withdrawal of heat from discharge gap, reduced dimensions of ozonizer and provision for preventing of dielectric coating on surfaces of electrodes from destruction.
