Patent ID: 8257469

Claim:
An electrostatic filter for the separation of dust particles from a gas stream with minimum one collecting electrode ( 3 - 7 ) fixed in a housing through which the gas flows and with a discharge electrode ( 16 - 20 ) arranged parallel to it at a distance, as well as equipment for the cleaning of the collecting electrode ( 3 - 7 ) working periodically, wherein the discharge electrode ( 16 - 20 ) is part of a cable ( 28 ) in which a cleaning equipment ( 33 ) is fixed and this cable ( 28 ) is connected to a drive system ( 27 , 31 , 32 ) for the execution of a cleaning movement, wherein at least a part of the cable ( 28 ) having the discharge electrode ( 16 - 20 ) can be wound on a coiling drum ( 27 ) for the execution of a cleaning movement of the cleaning equipment ( 33 ), and wherein the discharge electrode ( 16 - 20 ) is fixed between an upper and lower insulator provided in the cable ( 29 , 30 ).
