Apparatus for confinement of the short-lived hydroxyradical OH associated with ozone reaction processes
First Claim
1. Apparatus for promoting the production of hydroxyradical OH in the course of a reaction of ozone with water, and to confine said hydroxyradical OH reaction products for mixing with the water circulating stream of a pool, comprising:
- a venturi nozzle connected to convey said circulating stream and including a low pressure port;
a confining cavity defined by an upstream and a downstream end having said downstream end connected to said low pressure port;
an air flow restricting ozone generating assembly including an inlet end and an outlet end at the edges of spaced electrodes therebetween connected at said outlet end to said upstream end of said confining cavity; and
a pressure actuated valve assembly communicating with the adjacent atmosphere and connected to said inlet end of said ozone generating assembly; and
a feedback compensating electrical excitation circuit connected across said spaced electrodes.

Abstract
The output of a flow restricting ozone generator assembly is connected through a conveying chamber to a low pressure port of a venturi nozzle which is inserted into the water circulating plumbing of a pool or spa. The conveying chamber then stores the water vapors from the water flow through the nozzle which are communicated to the ozone generator to promote the reaction products hydroxyradical OH that is then drawn through the port to mix with the circulating water flow. A spring biased valve at the inlet to the ozone generator is urged to close upon the instance when the flow through the nozzle ceases, terminating the low pressure at its throat and thereby fully confusing the reaction products from inadvertent escape.

7. A method for promoting and thereafter confining the reaction products hydroxyradical OH produced in the course of a reaction of ozone with water within the circulating water stream of a pool, comprising the steps of:
-
generating a low pressure source by accelerating said circulating water stream through a reduced section of a venturi nozzle; communicating said low pressure to the outlet of an ozone generator cell dimensioned to form a flow restriction between the electrodes thereof; and connecting the inlet of said generator cell to the atmosphere across a pressure actuated valve assembly. - View Dependent Claims (8, 9)
