| 20100290171 | METHOD AND DEVICE FOR PRODUCING A BIPOLAR IONIC ATMOSPHERE USING A DIELECTRIC BARRIER DISCHARGE - A method produces a bipolar ionic atmosphere using a dielectric barrier discharge, and to a device suitable for carrying out the method. The solution for achieving this aim is to trigger an electrical surface discharge at more or less regular intervals on the wall of a channel through which a gaseous medium flows. The flow channel is formed by a dielectric and a wall electrode such that the channel wall consists in the direction of flow alternately of a conductive electrode material and a dielectric. In principle it will suffice if the channel is formed of only one dielectric and one conductive section which adjoin each other. The electrical surface discharge is triggered by a second electrode which is separated by the dielectric from the wall electrode and the flow channel, and to which a temporally varying high voltage is applied by an impulse generator. | 11-18-2010 |
