Abstract

La présente invention concerne un appareil de nettoyage respectueux de l'environnement et un procédé de nettoyage qui améliorent considérablement la performance de nettoyage en nettoyant pendant une courte période de temps sans causer de pollution extérieure, en installant un filtre à particules diesel (DPS) devant être nettoyé par alimentation d'une solution de nettoyage dans un bain de nettoyage ayant une structure simple de manière à ce qu'il soit immergé dans la solution de nettoyage, et en injectant la solution de nettoyage et de l'air comprimé à travers une entrée et une sortie du DPS tout en faisant tourner le DPS dans un état immergé dans la solution de nettoyage liquide. Afin de réaliser l'objectif technique, la présente invention fournit un appareil de nettoyage pour un DPS qui comprend : un bain de nettoyage (10) ; une plaque de base (20) ; un dispositif rotatif (30) ; des première et deuxième tiges de buse (50, 60) ; et un moyen de commande (non illustré). Selon la présente invention, afin de pouvoir nettoyer le DPS (1) tout en faisant tourner le DPS (1) dans un état immergé dans la solution de nettoyage qui est un milieu de grande densité, la présente invention comprend un moyen de support (40) pour supporter le DPS (1) dans la direction d'une entrée (2) et d'une sortie (3) du DPS, de telle sorte que le DPS (1) puisse être tourné sans s'écarter d'une position régulière, et en termes du procédé de nettoyage, la solution de nettoyage (5) et l'air comprimé sont injectés conjointement dans le DPS (10), ce qui réduit ainsi le temps de nettoyage et améliore la performance de nettoyage.
