Abstract

APPAREILLAGE ET PROCEDE D'EPURATION A CONTRE-COURANT DE LA PATE A PAPIER AFIN DE SEPARER LES FIBRES DESTINEES AU PAPIER DES ELEMENTS POLLUANTS DE DENSITE MOINDRE. IL COMPREND UN EPURATEUR CENTRIFUGE A CONTRE-COURANT DONT L'ORIFICE D'ADMISSION PRESENTE UNE SURFACE D'ECOULEMENT TRES SUPERIEURE A CELLE DES ORIFICES D'ADMISSION DES EPURATEURS CENTRIFUGES A CONTRE-COURANT CLASSIQUES. LA SURFACE D'ECOULEMENT DE CHACUN DES ORIFICES DE SORTIE DU SOMMET ET DE LA BASE EST SUPERIEURE A CELLE DE L'ORIFICE D'ADMISSION ET LES COURANTS EVACUES SONT REGLES DE FACON QUE LE DEBIT DE PATE EPUREE QUI S'ECOULE PAR L'ORIFICE DU SOMMET SOIT INFERIEUR AU DEBIT DES REBUTS PAR L'ORIFICE DE LA BASE. APPLICATION A L'EPURATION DE LA PATE REALISEE AVEC DES DECHETS DE PAPIER ET DE CARTON ET DESTINEE A LA FABRICATION DE PAPIER NEUF.
