Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Regeneration eines offenen Partikelabscheiders, umfassend zumindest folgende Schritte: a) Ermitteln mindestens eines Parameters (7) als Kenngröße für die Regenerationsfähigkeit des offenen Partikelabscheiders (1); b) Vergleichen des mindestens einen Parameters (7) mit einem ersten Schwellwert (4); c) Bestimmung mindestens eines Anteils (3) von einem Vergleichszeitraum (2), zu dem der Parameter (7) den ersten Schwellwert (4) erreicht hat; d) Vergleichen des Anteils (3) mit einem ersten Mindestanteil, der einer Mindestregenerationszeit im Vergleichszeitraum (2) entspricht; und e) Einleiten von Maßnahmen zur Beeinflussung des Parameters (7), so dass dieser wenigstens entsprechend dem ersten Mindestanteil liegt und der erste Schwellwert (4) erreicht ist und/oder der offene Partikelabscheider (1) regeneriert wird.
(EN)
The invention relates to a method for regenerating an open particle separator, comprising at least the following steps: a) establishing at least one parameter (7) as a characteristic of the regeneration capability of the open particle separator (1); b) comparing the at least one parameter (7) with a first threshold value (4); c) determining at least one portion (3) of a comparison time period (2) at which the parameter (7) has reached the first threshold value (4); d) comparing the portion (3) having a first minimum portion that corresponds to a minimum regeneration time in the comparison time period (2); and e) taking measures to influence the parameter (7) so that said parameter lies at least according to the first minimum portion and the first threshold (4) is reached and/or the open particle separator (1) is regenerated.
