Reactor for the plasma treatment of a gas flow, particularly exhaust gases produced by the internal combustion engine of a motor vehicle.

摘要

Reactor for treating gas flows with plasma, particularly for the treatment of exhaust gases produced by an internal combustion engine of a motor vehicle, comprising a reactor body (8) of generally elongated shape, made of a material dielectric and crossed by a plurality of parallel channels (10) extending longitudinally in said body, means of inlet and outlet (6, 7) for conducting the flow of gas to be treated through said body (8) and electrodes ( 14) created in said body corona discharges to stimulate in it the treatment of said gas flow, characterized in that each of said electrodes (14) is arranged in a channel (10) forming part of said plurality of channels (10) and it extends for at least a portion of the length of the corresponding channel, that the channels (10) are arranged side by side in the said reactor body (8) following longitudinal overlapping planes, in that said electronic ears (14) are arranged in at least two layers of parallel electrodes (12, 13) one of which comprises electrodes that will bind to one pole of high voltage source (21) and the other comprises electrodes to be disposed to join the other pole of said high voltage source (21) and in that said electrode layers (12, 13) are spaced apart a predetermined distance.
