Dielectric barrier discharge cell with hermetically sealed electrodes, apparatus and method for the treatment of odor and volatile organic compound contaminants in air emissions, and for purifying gases and sterilizing surfaces
A Dielectric Barrier Discharge Plasma Generation Cell includes a plurality of hot electrodes interspersed with a plurality of ground electrodes whereby a power supply connected between the hot and ground electrodes creates a non-thermal plasma between the electrodes. The hot electrodes are hermetically sealed by a rubber material such as a siloxane material surrounding portions of the hot electrodes. The cells are useful in odor removal systems to neutralize odors and VOC emissions in commercial and/or industrial air streams and in gas purification and sterilizing systems which utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and/or reduction of odor causing molecules, VOC's, and other contaminants. Where a plurality of cells are electrically connected in parallel, shorts in a cell can be detected by sensing the difference in currents feed to each of the plurality of cells.
