Abstract
Procédé de nettoyage de filtres à manches par balayage pneumatique à contre-courant. Une phase impulsionnelle suivie immédiatement d'une phase de balayage complémentaire consiste à provoquer un gonflement brusque de chaque manche suivi d'une phase finale au cours de laquelle un flux d'air de moindre intensité, mais de plus longue durée, permet au tissu filtrant de reprendre sa forme initiale très lentement. Application essentiellement aux filtres à basse pression utilisés notamment en meunerie pour la séparation et la récupération de la poussière de farine.
