<p>PCT No. PCT/SE96/00611 Sec. 371 Date Nov. 25, 1997 Sec. 102(e) Date Nov. 25, 1997 PCT Filed May 10, 1996 PCT Pub. No. WO97/00727 PCT Pub. Date Jan. 9, 1997A device in an electrostatic precipitator for suspending, controlling and rapping one or more collecting electrodes arranged essentially vertically in one or more substantially parallel rows includes, for each row, a substantially horizontally oriented carrier element, to which the upper ends of the collecting electrodes are attached, connecting elements which connect the carrier element to the casing of the electrostatic precipitator, a control arrangement for controlling the motion of each row of collecting electrodes in the transverse and/or longitudinal direction of the electrostatic precipitator, and a rapping mechanism for rapping the collecting electrodes of each row. The rapping mechanism includes a rapping device, such as a rapping hammer, and an anvil connected to the carrier element. The carrier element of each row is separately suspended by means of the connecting elements, thereby permitting, during rapping, a minimum horizontal pivoting motion restricted to each row of collecting electrodes and occurring in the longitudinal direction of the electrostatic precipitator.</p> |
