Method and device for preventing the deposition of soot on the insulating parts of a filter electrostatic

摘要

The invention relates to a method and device for preventing, in an electrostatic filter (1) comprising the insulating parts (2), the deposit of soot particles (3) on the insulating parts (2). the method comprises the step of creating a repellent electrical field (4) in the vicinity of the insulating parts (2): - by placing in or on at least one of the insulating parts (2) at least one repelling electrode (8), -, by applying to the repelling electrode (8) a voltage adéquate.la potential difference between the repelling electrode (8) and the central electrode (6), as well as the potential difference between the repelling electrode (8) and the peripheral electrode (7), creating a repellent electrical field (4), pushing the soot particles charged électriquement.on prevents the formation of a conductive channel (5) to the surface of the insulating parts (2) between said central electrode (6) and the peripheral electrode (7).
