Abstract:
1. An isolating device, comprising: a body rotating about an axis and generating a first power, wherein the body comprises a plurality of plate-shaped electrode structures to generate the first power, and each of the plate-shaped electrode structures forms a planar main surface; a first working fluid; a second working fluid; a first guiding portion penetrating through the plate-shaped electrode structures along a direction substantially perpendicular to the planar main surfaces of the plate-shaped electrode structures and guiding the first working fluid to pass through the body to form a first working region, wherein the first working fluid is isolated from the plate-shaped electrode structures by the first guiding portion; and at least two discrete second guiding portions spaced apart in a circumferential direction and penetrating through the plate-shaped electrode structures along the direction substantially perpendicular to the planar main surfaces of the plate-shaped electrode structures, rotating about the axis and guiding the second working fluid to pass through the body, wherein the second working fluid is isolated from the plate-shaped electrode structures by the second guiding portions, and the plate-shaped electrode structures generate an electrical field substantially parallel to the first and second guiding portions; wherein the second working fluid is excited by the first power entirely generated by the plate-shaped electrode structures of the body to form a second working region which rotates about the axis and forms a plasma curtain for isolating the first working region.
