Device in electrostatic precipitator for suspending, controlling and rapping of collecting electrodes

一种在静电吸尘器内用于悬挂、控制和振打一个或多个集电电极(2)的装置，这些电极基本上垂直地排成一个或多个基本平行的排(1)，该装置包括用于每一排(1)的一基本上水平取向的承载件(3)；集电电极(2)的上端连接于承载件；连接元件(4a、4b)，其将承载件连接于静电吸尘器的壳体(5)上；控制装置(11a、11b、12a、12b、13、14a、14b)，用于控制各排(1)集电电极在静电吸尘器的横向和/或纵向上的运动；一振打机构(6)，用于振打各排集电电极，该振打机构包含一振打装置(7)，例如一振打锤和一连接于承载件(3)上的一砧座(9)。各排的承载件(3)由所述连接件(4a、4b)单独悬挂，因此，在振打过程中允许发生在静电吸尘器的纵向的一种相对于各集电电极排(1)有限制的最小水平枢轴运动。 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.
