Abstract:
1. A surface dielectric barrier discharge plasma unit comprising: a solid dielectric structure provided with an interior space wherein an interior electrode is arranged, further comprising an exterior electrode for generating in concert with the interior electrode a surface dielectric barrier discharge plasma; a gas flow path along a surface of the solid dielectric structure and wherein the gas flow path is oriented substantially transverse with respect to a treating plane of the solid dielectric structure; wherein the solid dielectric structure substantially has an elongate shape having a top surface, defined as an exterior treating surface during operation of the unit, and an exterior side surface extending from the top surface and substantially transverse thereto, along which side surface at least a part of the gas flow path is located; wherein the gas flow path is oriented substantially transverse with respect to the top surface of the solid dielectric structure; and wherein the exterior side surface of the solid dielectric structure is at least partially covered by the exterior electrode; a cap structure surrounding the solid dielectric structure, opposite to the top surface, the cap structure being provided with an entry for flowing gas towards gas path along exterior side surfaces of the solid dielectric structure; and a conveyor configured to carry objects to be treated along and parallel to the top surface in a direction of a treatment path for the objects.
