Abstract:
1. An atmospheric plasma generator, comprising: a casing comprising an insulator; a longitudinal columnar plasma-generating zone which is defined by the casing; a first electrode and a second electrode which are separately disposed at both ends along a longitudinal axis of the longitudinal columnar plasma-generating zone and a surface of the first electrode faces a surface of the second electrode in a longitudinal direction of the longitudinal columnar plasma-generating zone, a distance between the first electrode and the second electrode defining a longitudinal length of the longitudinal columnar plasma-generating zone; a plasma-generating gas inlet for supplying a plasma-generating gas to the longitudinal columnar plasma-generating zone in a first direction normal to the longitudinal direction of the longitudinal columnar plasma-generating zone; and at least one outlet for jetting a gas comprising at least a plasma in the first direction normal to the longitudinal direction of the longitudinal columnar plasma-generating zone, in which the at least one outlet is provided along the longitudinal direction of the longitudinal columnar plasma-generating zone, wherein the longitudinal columnar plasma-generating zone comprises one continuous space in an atmospheric pressure between the surface of the first electrode and the surface of the second electrode, wherein the longitudinal length of the longitudinal columnar plasma-generating zone, in the longitudinal direction, is more than a width, which is perpendicular to the longitudinal direction and to the first direction, of the longitudinal columnar plasma-generating zone, and wherein the surface of the first electrode and the surface of the second electrode are exposed to, and in contact with, the plasma-generating gas, and a linear electric discharge is generated between the surface of the first electrode and the surface of the second electrode.
