Abstract
Dispositif de mise en contact liquide-solide à contre-courant. Ce dispositif comprend une unité combinée de colonnes de filtration et de régénération empilées l'une sur l'autre ; la colonne de filtration a une entrée et une sortie de liquide, un milieu liquide à purifier étant fourni dans la colonne de filtration à travers l'entrée de liquide et évacué à l'extérieur à travers la sortie de liquide après avoir monté à travers un lit de matière de filtration dans la colonne de filtration; la colonne de régénération a son extrémité inférieure s'ouvrant dans la colonne de filtration et fournit une matière de filtration en quantité nécessaire pour compenser la réduction de quantité de matière de filtration dans la colonne de filtration chaque fois qu'une partie de la matière de filtration dans une région inférieure de la colonne de filtration est retirée et ramenée dans la colonne de régénération. La présente invention est particulièrement utile pour fournir des dispositifs de mise en contact liquide-solide à contre-courant permettant l'épuration de liquides salis.
