Abstract

The invention relates to a discharge electrode (30) produced from metal sheet and intended for use in an electrostatic dust precipitator which in addition to incorporating the discharge electrode also incorporates one or more collector electrodes. A voltage source is provided for supplying energy to the discharge and collector electrodes, so as to create therebetween a high d.c. voltage and an electrostatic field which separates dust from a dust-laden medium flowing through the precipitator, this dust settling primarily on the collector electrode. The discharge electrode comprises an elongated member (30) having distributed therealong a plurality of electrode parts presenting one or more discharge tips (37a, 37b, 38a, 38b). The electrode parts extend transversally to the longitudinal axis of the elongated member and project beyond the outer defining surfaces thereof. The elongated member (30) is formed from a folded or like corrugated metal sheet, with the folds (31,32,33,34,35) oriented in the longitudinal direction of the elongated member.
