Abstract

L'invention concerne une installation de dépoussiérage (1) comprenant une chambre de traitement (2) dans laquelle de la poussière est introduite à partir d'un flux volumique (3) chargé de poussière par le biais d'une entrée de flux volumique (23) et séparée, au moins un élément filtrant (4) étant disposé dans la chambre de traitement (2), à travers lequel le flux volumique (3) est attiré et au moyen duquel la chambre de traitement (2) est divisée en un côté gaz brut (21) et un côté gaz purifié (22), un dispositif de nettoyage (5) étant prévu, lequel peut produire, pour le nettoyage dudit au moins un élément filtrant (4), un flux de gaz de nettoyage (32) à partir du côté gaz purifié (22) vers le côté gaz brut (21) en sens inverse à la direction de flux volumique normale à l'opposé du ou des éléments filtrants, la chambre de traitement (2) comprenant, sur le côté gaz brut (21), une ouverture de dérivation à contre-courant (33) supplémentaire, par le biais de laquelle le flux de gaz de nettoyage (32) peut s'échapper à partir du côté gaz brut (21) vers l'extérieur de celui-ci, un élément filtrant de dérivation (6) filtrant le flux de gaz de nettoyage (31) étant disposé dans ou sur l'ouverture de dérivation à contre-courant (33), un dispositif de fermeture (7) étant disposé dans ou sur l'ouverture de dérivation à contre-courant (33) de telle sorte qu'en cas de direction de flux volumique normale du flux volumique (3) chargé de poussière, l'ouverture de dérivation à contre-courant (33) soit fermée.
