Abstract
Abstract An electrostatic precipitator for cleaning exhaust gases through ionization, including a high voltage generator installed in a stationary insulator within a chimney flue. The stationary insulator supports a carrying axle onto which a number of hollow high potential discharge electrodes are mounted and which has a direct electrical contact with the high voltage generator output. The carrying axle conducts a voltage produced by the generator to the mounted electrodes. The chimney flue serves as a discharge channel in which a collecting electrode is provided in the form of a continuous film of water flowing down along the inside walls of the chimney flue.
