ABSTRACT:
An impact device (15) applies hammer-like blows, or impact forces, to a metallic support frame (13) from which high-voltage electrodes (10) are suspended in an electrostatic precipitator in order to dislodge accumulated particulates from high-voltage electrodes (10). The impact device (15) is electrically isolated by an insulator (19) from metallic components of the precipitator other than the support frame (13) and components electrically connected to the support frame (13). The insulator (19) has a bore (18) that accommodates movement of the impact device (15) from a withdrawn position away from the support frame (13) to an impact position in contact with the support frame (13) upon energization and de-energization of a solenoid (17). The insulator (19) remains unstressed as the impact device (15) contacts the support frame (13).
