ABSTRACT:
There is provided a static eliminator capable of improving a sheath effect exerted by shielding a leading end of a discharge electrode by a clean gas so as to prevent the leading end of the discharge electrode from being contaminated, in which a first-stage circumferential chamber, a second-stage circumferential chamber and a first gas pool are arrayed in series along the longitudinal direction of a discharge electrode, the first gas pool is disposed in the mode of diametrically overlapping a gas outflow channel for shielding located on the inner circumferential side of the first gas pool, and a clean gas is supplied to the first gas pool through the chambers disposed at multi-stages by means of the circumferentially spaced multi-stage orifices (the first and second chases).
