Abstract
Abstract A static diffuser for use within the water tank of an ozonator system. The diffuser comprises a depending water pipe into which water is fed under pressure by an external pump. The lower end of the pipe flares outward and has an internal fixed cone which combines with the flared end of the pipe to provide an annular laterally directed water discharge. The annular discharge includes angularly directed vanes to enhance the water discharge and assist in forming a high velocity outwardly directed circular sheet of water. The pipe is surrounded, in spaced relation, by a shroud through which the ozone is introduced. The shroud is provided with an annular slot outward of the pipe discharge, the shape of the shroud at the slot forming a modified 360° circular venturi whereby the discharging high velocity sheet of water creates a negative pressure drawing the ozone therewith into the surrounding body of water for a ozonation thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
For use in an ozonator system incorporating a tank within which liquid is to be ozonated; a static diffuser, said diffuser comprising a liquid feed pipe having a discharge end portion adapted for positioning within the tank below the level of liquid within the tank, said discharge end portion being outwardly flared, a static flow modifier positioned within the flared discharge end portion and defining therewith a liquid discharge opening laterally directed relative to said pipe, means for producing a pressurized flow of liquid through said pipe and out said discharge opening, an ozone feeding shroud outward of and generally paralleling said pipe, a discharge slot in said shroud in outwardly aligned relation with said discharge opening for passage of discharging liquid therethrough, said shroud, at the shroud slot, defining a general venturi configuration for acceleration of the liquid passing therethrough and entrainment of ozone within the discharging liquid.
Claim 2
Dependent Claim
149 words
For use in an ozonator system incorporating a tank within which liquid is to be ozonated; a static diffuser, said diffuser comprising a liquid feed pipe having a discharge end portion adapted for positioning within the tank below the level of liquid within the tank, said discharge end portion being outwardly flared, a static flow modifier positioned within the flared discharge end portion and defining therewith a liquid discharge opening laterally directed relative to said pipe, means for producing a pressurized flow of liquid through said pipe and out said discharge opening, an ozone feeding shroud outward of and generally paralleling said pipe, a discharge slot in said shroud in outwardly aligned relation with said discharge opening for passage of discharging liquid therethrough, said shroud, at the shroud slot, defining a general venturi configuration for acceleration of the liquid passing therethrough and entrainment of ozone within the discharging liquid.
Claim 3
Dependent Claim
39 words
The diffuser of claim 1 wherein the flared end portion of the pipe is circular, said flow modifier being positioned centrally therein with the defined liquid discharge opening being circular for a discharge of liquid in an annular sheet.
Claim 4
Dependent Claim
33 words
The diffuser of claim 2 wherein said flow modifier is of a conical configuration with a peripheral wall generally paralleling the outward flare of the surrounding discharge end portion of the feed pipe.
Claim 5
Dependent Claim
41 words
The diffuser of claim 3 wherein the conically configured modifier and surrounding discharge end portion of the feed pipe define an annular flow chamber therebetween which generally decreases in size toward the discharge opening for an acceleration of liquid passing therethrough.
Claim 6
Dependent Claim
36 words
The diffuser of claim 4 including multiple vanes positioned within the liquid discharge opening peripherally about the flared discharge end portion, said vanes being similarly angularly directed for effecting a circular movement of the discharging liquid.
Claim 7
Dependent Claim
36 words
The diffuser of claim 3 including multiple vanes positioned within the liquid discharge opening peripherally about the flared discharge end portion, said vanes being similarly angularly directed for effecting a circular movement of the discharging liquid.
Claim 8
Dependent Claim
22 words
The diffuser of claim 6 wherein the discharge end portion of the feed pipe is separately formed therefrom and releasably mounted thereon.
