摘要： The invention is a method and system for the generation of high voltage, pulsed, periodic corona discharges capable of being used in the presence of conductive liquid droplets. The method and system can be used, for example, in different devices for cleaning of gaseous or liquid media using pulsed corona discharge. Specially designed electrodes and an inductor increase the efficiency of the system, permit the plasma chemical oxidation of detrimental impurities, and increase the range of stable discharge operations in the presence of droplets of water or other conductive liquids in the discharge chamber.

摘要： The present invention relates to devices for producing ozone, wherein said devices use a pulsed corona discharge such that there is no need for a dielectric in the electrode gap. This invention may be used to increase the ozone concentration above 20 g/standard m (a concentration required for the practical use of an ozonator), while reducing the power consumption necessary for producing ozone down to 10 kW-hr/kg of ozone in an ozonator that uses such pulsed corona discharge. In order to achieve such results, this invention proposes an ozonator for producing ozone in a pulsed corona discharge, wherein said discharge is ignited by sending short pulses (less than 500 nanosec.) having a high voltage and a positive polarity onto a corona-generating electrode. The electrode not generating a corona or at least the part thereof which is in contact with said discharge is made of aluminium, an aluminium alloy or a conductive alloy having a thermal conductivity exceeding 50 W/m*degree. The high-voltage pulse source is provided with a high-voltage on/off function and generates a pulsed corona discharge having a specific power exceeding 50 W/l. The frequency between successive pulses is higher than 500 Hz, while the ratio between the amplitude of the high-voltage pulses and the amplitude of the remaining DC voltage between said pulses is 1.5-3.
