Abstract

Cette invention concerne un distributeur de fluidisation conçu pour acheminer de la poudre d'alumine dans le système de purification des fumées d'un procédé électrolytique de traitement d'aluminium. Le distributeur de fluidisation comprend une chambre de matériau conçue pour contenir et distribuer du matériau, de multiples boîtes distributrices conçues pour recevoir respectivement le matériau provenant de la chambre de matériau et le décharger vers l'extérieur, et une chambre à gaz conçue pour fournir l'air de fluidisation pour la chambre de matériau afin de fluidiser le matériau dans ladite chambre. Ladite chambre de matériau est agencée horizontalement ou quasi-horizontalement, et elle communique avec la boîte distributrice à travers un tuyau distributeur et une buse distributrice. Du fait d'une différence de hauteur réduite entre la chambre de matériau et la boîte distributrice et du fait de la fluidisation du matériau dans la chambre de matériau, la surface supérieure du matériau dans la chambre tend à être horizontale, et une relative homogénéité peut être obtenue en vue de la distribution. Ainsi, l'alumine en poudre peut être efficacement distribuée vers plusieurs endroits avec des résultats meilleurs, et l'efficacité de la purification des fumées dans l'électrolyse de l'aluminium peut être assurée et améliorée. En outre, le coût du distributeur est moindre et sa structure est simple, ce qui facilite sa fabrication.
