Ozone Generation System

Abstract

An ozone generation system which is adaptable for supplying ozone to different medium and small application processes. The system has a source of feed gas, a corona discharge cell receiving the feed gas from the feed gas source and generating ozone for the application process, a flow controller measuring and managing the flow of the feed gas from the feed gas source to the corona discharge cell; and a regulator receiving gas from the corona discharge cell and sending the gas to the application process. The regulator maintains pressure in the corona discharge cell independent of the application process pressure.

The invention claimed is: 
     
         1 . An ozone generation system for supplying ozone to an application process, the system comprising:
 a source of feed gas;   a corona discharge cell receiving the feed gas from the feed gas source and generating ozone for the application process;   a flow controller measuring and managing the flow of the feed gas from the feed gas source to the corona discharge cell, the controller including
 a first valve controlling the flow from the feed gas source to the corona discharge cell, the valve responsive to electrical control signals; and 
 an electronics system adjusting the valve to maintain a constant flow from the feed gas source to the corona discharge cell, the electronics system generating the electrical control signals responsive to calculations of flow of the feed gas through an orifice; 
 an orifice through which the feed gas flows; 
 a first pressure transducer measuring a differential gas pressure across the orifice and at intervals measuring a zero differential pressure to recalibrate the first pressure transducer; and 
   a regulator maintaining pressure in the corona discharge cell independent of pressure in the application process.   
     
     
         2 . A flow controller for measuring and managing flow of a feed gas from a feed gas source to a corona discharge cell in an ozone generation system, comprising:
 a first valve controlling the flow from the feed gas source to the corona discharge cell, the valve responsive to electrical control signals;   an electronics system adjusting the valve to maintain a constant flow from the feed gas source to the corona discharge cell, the electronics system generating the electrical control signals responsive to calculations of flow of the feed gas through an orifice;   an orifice through which the feed gas flows; and   a first pressure transducer measuring a differential gas pressure across the orifice and at intervals measuring a zero differential pressure to recalibrate the first pressure transducer.
