A rapping mechanism for the rapping of discharge and field electrodes in a high voltage driven electrostatic precipitator used for the cleansing of smoke laden gases from industrial plants, power works etc. The rapping effect is obtained by metal balls which run from the top of the precipitator to its bottom along a number of sloping tracks which are mounted stepwise, with differences of level, on the electrodes or on the carrying frames of same. A single ball in connection with its changing from one track to the following track, when falling freely and moving horizontally, hits both the underlying track and a stop mounted near the lower end of the track thereby causing each electrode carrying frame to receive two consecutive blows of different force so that the frame is rapped and the deposited dust is loosened and falls off. A lifting device of known type carries the balls from a terminated passage down along the tracks to a starting position for a renewed passage of the tracks.
