Abstract

The apparatus for producing a desired quantity of ozone uses a flow of air in which a corona discharge utilizes high voltage to produce sparks. This apparatus includes a source of high voltage and the spark is produced when metal or conducting edge portions of the blades are moved in way of spaced conductors carried in a tubular confine. The blades are carried as an assembly which may be rotated by a flow of air. The flow of air and the turning of the assembly maintains the blades in a cooled condition so that unwanted burning of the edges of the blades does not occur. The corona discharged ozone may be used in swimming pools, or as an air purifier or dust eliminator. The ozone, when used in a closed building, will utilize a timer so an excess of ozone is not produced. The rotating of the bladed member is preferably by the flow of air, said volume of air flow regulates the speed of rotation.

Apparatus in and by which ozone is produced by a corona discharge in the presence of flowing air, said apparatus including:

(a) a source of high voltage delivered to said apparatus by at least first and second electrical current conductors;
(b) a housing adapted to receive said conductors and having a tubular confine in which a supporting means is formed and in which there is a plurality of adjustably mounted electrical conducting members carried in said supporting means and in current conducting association with one of said electrical conductors;
(c) a first electrical conductive means supported by and arranged about the tubular confine and connecting the adjustable means to one side of the source of high voltage;
(d) a shaft member positioned substantially at the axis of said tubular confine portion of the housing and carrying a plurality of substantially rigid and like positioned blades, each blade disposed in a plane substantially normal to the axis of the shaft and providing an assembly which is carried by associated bearing means, and as an assembly is moved in a rotational manner with each blade having electrical conducting means provided at its outer edge portions and as the blades are moved to sweep in a circular path;
(e) a second electrical conducting means leading from the source of high voltage to the conducting means provided at the outer edge portion of each blade;
(f) means for producing a rotation of the blade assembly, and
(g) means for conducting the produced ozone from within the tubular confine portion of the housing, said ozone produced by said corona discharge of high voltage when and as the conducting outer edge portions of the rotatably moving blades are brought near to, opposite and past a plurality of electrical conducting members spaced a selected distance from said conducting outer edge portion of the blades so that a corona discharge is discontinuously produced when and as the rotating blade is moved therepast and high voltage is caused to flow as an arc through an air supply.
