Device in connection with a circular precipitator for a two-stage electrostatic filter

Abstract

A device in connection with a circular precipitator (1) for a two-stage electrostatic filter, wherein the precipitator (1) is formed of at least two strip-like electrode elements wound around a centrally arranged bobbin and the electrode elements are arranged at a distance “d” from one another so that gaps are formed between the electrode elements, wherein the device includes elements for rotating the precipitator (1) about its center axis and wherein a vacuum cleaner nozzle (27) is arranged on one side of the precipitator (1), the vacuum cleaner nozzle (27) being situated in the immediate vicinity of the precipitator (1). It is significant for the device that the vacuum cleaner nozzle (27) is provided with at least two elements (35/36) designed to penetrate into the gaps between adjacent electrode elements of the precipitator (1).
