Abstract:
1. Apparatus for treatment of odor and volatile organic compound contaminants in gas emissions and for purifying gases, comprising: a dielectric barrier discharge non-thermal plasma (NTP) generation cell having a gas flow path therethrough, said cell having a plurality of electrically hot electrodes and ground electrodes positioned in the gas flow path so that gas flowing in the gas flow path will flow across a portion of these electrodes, at least the hot electrodes being hermetically sealed across the gas flow portion of the electrodes; a cell gas inlet leading to the gas flow path through the cell; a cell gas outlet for discharging gas that has passed through the cell; a source of cleaning solution to be applied to the electrodes in the cell to wash gas stream contaminants and/or reaction by-products off the electrodes; and a plurality of nozzles in fluid flow communication with the source of cleaning solution and directed toward the electrodes to spray cleaning solution onto the electrodes at selected times during operation of the cell when desired to clean the electrodes.
