Abstract: A rigid discharge electrode (2) intended for use in an electrostatic precipitator which, in addition to the discharge electrode, also includes 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 electric field, causing dust to be separated from a dust-laden medium passing between the electrodes, this separated dust settling primarily on the collector electrodes. The discharge electrode comprises a rod-like member (10) having attached therealong a plurality of electrode parts (17,18) presenting one or more discharge tips. The electrode parts extend transversely to the longitudinal axis of the rod-like member and project beyond the outer defining surfaces thereof. The rod-like member (10) presents two mutually opposite and mutually parallel surfaces (19,19'), and elonagated electrode parts (17,18) presenting discharge tips (17a,17b) are attached to or fitted on these surfaces.

Abstract: An electrode holding arrangement (11,12,13,14,15) forming part of an electrostatic percipitator and intended for supporting a plurality of discharge electrodes (2). In addition to the discharge electrodes (2) the precipitator also incorporates one or more collector electrodes (25), and a voltage source for supplying energy to the discharge and collector electrodes so as to create therebetween a high D.C. voltage which influences dust carried in a dust-laden medium passing between the discharge and collector electrodes in a manner to separate dust from the medium, this dust falling primarily on the collector electrodes. Respective discharge electrodes comprise a rod-like flexurily rigid member having attached thereto, or formed integrally therewith electrode parts which present discharge tips. A predetermined number of discharge electrodes (2) are attached at their upper end parts (2a) to a common, elongated, horizontallly extending electrode holding device (11).
