Abstract:
A system for generating ozone by corona discharge, comprising:a plurality of corona discharge ozone generating cells each disposed respectively in one of a plurality of flow branches; a plurality of flow control orifices each disposed in one of the flow branches upstream of and coupled to the corona discharge ozone generating cell in the flow branch for controlling a flow of incoming gas to the corona discharge ozone generating cell for producing an ozone-containing gas in the flow branch from the incoming gas by corona discharge; an upstream pressure regulator disposed upstream of and coupled to the plurality of corona discharge ozone generating cells in the flow branches in parallel for setting and automatically maintaining a desired inlet pressure of the incoming gas entering each corona discharge ozone generating cell; and a plurality of downstream pressure regulators each disposed in one of the flow branches downstream of and coupled to the corona discharge ozone generating cell in the flow branch for setting and automatically maintaining a separate, desired cell pressure for the corona discharge ozone generating cell in each flow branch so that effects of variances caused by processing of the ozone-containing gas downstream of the corona discharge ozone generating cell and the downstream pressure regulator on ozone production by the ozone generating cell in each flow branch are at least substantially eliminated.
