Emission electrode in an electrostatic dust separator

Abstract

The emission electrode (12) has a support section (16), which imparts mechanical strength, with emission tips (20) disposed in at least two rows and directed on both sides towards adjacent collecting electrodes. It is composed of a single-piece metal sheet symmetrically folded to form the support section (16) which metal sheet has emission arms (18) which are integrally formed outside the folded support section (16) and extend over its entire active length (1) along the central plane (E) between the collecting electrodes (10) and which have emission tips (20) extending in the plane (E) or directed on both sides towards the adjacent collecting electrodes. The metal sheet is bent through more than a right angle on the inside of the emission arms (18) to form a double loop. To produce the emission electrode (12) a metal sheet having integrally formed emission arms (18) slotted at the front apices (19) is punched out "in-line" and cold-worked in the longitudinal direction to form the folded support section (16) on the inside of the emission arms (18). The emission tips are bent in the same operation.
