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.

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;
- 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;
- a second pressure transducer measuring the corona discharge cell pressure;
- a temperature transducer measuring temperature of the gas flow at the orifice;
- and
- an electronics system adjusting the first valve to maintain a constant flow from the feed gas source to the corona discharge cell, the electronics system generating the electrical control signals from calculations of flow of the feed gas through the orifice responsive to electrical signals from the first pressure transducer, the second pressure transducer and the temperature transducer;
- and
- a regulator maintaining pressure in the corona discharge cell independent of pressure in the application process.
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;
- and
- a regulator receiving gas from the corona discharge cell and sending the gas to the application process, the regulator further comprising:
- a block with an inlet for receiving gas from the corona discharge cell and an outlet for sending the gas to the application process;
- a flexible diaphragm disposed with respect to the block to cover the inlet and outlet;
- and
- a subsystem biasing the diaphragm against the inlet and outlet by gas pressure so that the pressure of the gas flow from the inlet to the outlet is controlled by the gas pressure of the subsystem against the diaphragm;
- whereby the regulator maintains pressure in the corona discharge cell independent of pressure in the application process.
