Abstract: A discharge electrode for electrostatic precipitators has a support composed of an electrically non-conductive material, a fabric composed of crossed and twisted threads and disposed on an exterior of the support, the support having an upper end and a lower end, and further comprising an additional layer of a synthetic elastomer which covers at least one of the ends over a length of 400-600 mm. Also, an electrostatic precipitator for treatment of exhaust gasses containing SO.sub.2, SO.sub.3, HF or HCL is proposed with the new discharge electrode.

Abstract: Selfsupporting mastlike corona discharge electrodes are proposed for use in a dustcollecting electrostatic precipitator having gas passage-forming platelike collecting electrodes. From a metal strip which has the same width everywhere the corona discharge electrode can be manufactured continuously in any desired length and virtually without a waste of material. By cutting and bending operations the metal strip is formed to constitute a selfsupporting corona discharge electrode which has an adequate flexural stiffness and is provided with the required corona discharge tips.
