Abstract

Appareil servant à réaliser un procédé de nettoyage de surfaces de bâtiments, qui comprend une chambre (11) compartimentée en zones inférieure et supérieure (35a, 35b) par un moyen de limitation pyramidal (33). Un gaz à vitesse lente est introduit à partir d'un corps perforé (15) pour fluidifier un lit de matériau particulaire (13) possédant une certaine énergie et s'évacuant vers une pièce manuelle (21) par l'intermédiaire d'un moyen d'évacuation (19). Le lit est maintenu en condition stable par la descente sous gravité du matériau particulaire (37) retenu par le moyen de limitation (33). Le matériau (37) et le matériau (13) forment un continuum au passage de communication périphérique (41) du moyen de limitation. Un gaz à vitesse élevée traversant le passage (25) et six passages (95) dans un élément créant un tourbillon (79) entraîne les particules transportées par le gaz à vitesse lente le long du passage (23) à la jonction (27) du passage (23) avec les passages (95). Quand le matériau particulaire atteint la jonction, il est immédiatement accéléré par le gaz à vitesse élevée jusqu'à sa vitesse d'évacuation de la pièce manuelle.
