Abstract

Procédé de centrifugation d'huiles usées, par l'utilisation d'un séparateur dont le tambour centrifuge 1 est alimenté par une entrée centrale 2 et présente un conduit de sortie 9 pour le liquide soutiré de la zone centrale et un conduit de sortie 10 pour le liquide soutiré de la zone périphérique, les substances solides et l'eau étant acculées dans la chambre de substance solide 5 et le liquide soutiré de la zone périphérique étant recyclé dans l'entrée tant que de l'huile s'écoule, le recyclage étant terminé aussitot que de l'eau s'écoule.Process for centrifuging used oils, by using a separator, the centrifugal drum 1 of which is fed by a central inlet 2 and has an outlet duct 9 for the liquid withdrawn from the central area and an outlet duct 10 for the liquid withdrawn from the peripheral zone, the solid substances and the water being forced into the solid substance chamber 5 and the liquid withdrawn from the peripheral zone being recycled into the inlet as long as oil flows, recycling being finished as soon as water flows out.
