PLASMACHEMICAL PROCESS FOR DECOMPOSING AND/OR DESTROYING POLLUTANTS, IN PARTICULAR FOR CLEANING EXHAUST FUMES OF INTERNAL COMBUSTION ENGINES OR OTHER FOSSIL FUEL DRIVEN MACHINES, AND DEVICE THEREFOR
PLASMACHEMICAL PROCESS FOR DECOMPOSING AND/OR DESTROYING POLLUTANTS, IN PARTICULAR FOR CLEANING EXHAUST FUMES OF INTERNAL COMBUSTION ENGINES OR OTHER FOSSIL FUEL DRIVEN MACHINES, AND DEVICE THEREFOR
An undesirable gaseous or fine particulate substance runs together with admixed substances which influence plasmachemical reactions through a section to which dielectrically inhibited ('silent') discharges are applied. According to the invention all process parameters of the plasmachemical reactions are regulated in such a way that the desired cleavage of the pollutants is maximized and the occurrence of undesirable reactions, in particular ozone generation, is minimized. In a device suitable for carrying out this process, a guiding path (5) for the pollutants, including inlets (6, 7) for the admixed substances, is associated with an electrode arrangement (4), and means (3, 30-35) are provided for regulating the electric power and for ensuring a defined temperature of the pollutants to be processed.
