Abstract
A mechanism for rapping the electrodes of an electrostatic precipitator for the purpose of dislodging dust deposited on the electrodes is disclosed. The rapping mechanism incorporates a pair of impact beams (1, 1') between which collecting electrodes are suspended. The impact beams are so arranged that the beams slide on the upward-facing edges of a pair of support carriers (2, 2') secured to the precipitator housing. A drop hammer (7) rotatable about a horizontal shaft raps an anvil (6) secured to the impact beam pair (1, 1'), thereby causing a horizontal vibration of the impact beam pair (1, 1') without imparting any impact energy to the precipitator housing. A pair of springs (12) secured to the precipitator housing, one at each end of the impact beam pair, act against the horizontal movement of the impact beam pair and restore the impact beam pair to its original position.
