<p>A device in an electrostatic precipitator for suspending, controlling and rapping one or more collecting electrodes (2) arranged essentially vertically in one or more substantially parallel rows (1), said device comprising for each row (1) a substantially horizontally oriented carrier element (3), to which the upper ends of the collecting electrodes (2) are attached, connecting elements (4a, 4b) which connect the carrier element to the casing (5) of the electrostatic precipitator, control means (11a, 11b, 12a, 12b, 13, 14a, 14b) for controlling the motion of each row (1) of collecting electrodes in the transverse and/or longitudinal direction of the electrostatic precipitator, and a rapping mechanism (6) for rapping the collecting electrodes (2) of each row, comprising a rapping means (7), such as a rapping hammer, and an anvil (9) connected to the carrier element (3). The carrier element (3) of each row is separately suspended by means of said connecting elements (4a, 4b), thereby permitting, during rapping, a minimum horizontal pivoting motion restricted to each row (1) of collecting electrodes and occurring in the longitudinal direction of the electrostatic precipitator.</p> |
