Non-thermal plasma reactor and exhaust line of a motor vehicle comprising this reactor.

摘要

Reactor nonthermal plasma (16) for treating the exhaust gases of a motor vehicle, of the type comprising an enclosure circulation of exhaust gases in which is housed a bundle of individual reactors (20) extending all substantially parallel to a flow direction of exhaust gas, each elementary reactor (20) a first (22) and second (24) electrodoas, intended to be brought to different potentials, separated by a dielectric barrier (26) having comprising a generally tubular shape, the first electrode (22) a generally rod extending substantially coaxially in the dielectric barrier (26) and having the second electrode (24) having a generally cylindrical envelope extending substantially coaxially around the barrier (26), with the individual reactors (20) supported by a barrel (30) comprising at least one plate (32) conductive radial bracing of the individual reactors (20) substantially perpendicular to the direction of flow of the exhaust gases, characterized in that the plate (32) is electrically connected to each second electrode (24) of elementary reactor (20), the second electrodes (24) of elementary reactors material coming out of the plate (32) of the radial bracing.
