Abstract

L'INVENTION A POUR OBJET UNE INSTALLATION ET UN PROCEDE PERFECTIONNES DE PREPARATION D'UNE PATE A PAPIER A PARTIR D'UNE MATIERE LIGNOCELLULOSIQUE REDUITE EN MORCEAUX ET PREALABLEMENT IMPREGNEE D'UN REACTIF ELIMINE ENSUITE PAR LAVAGE EFFECTUE PROGRESSIVEMENT PAR UNE SERIE D'ETAPES SUCCESSIVES, DE DILUTION ET DE FILTRATION. SELON L'INVENTION, L'ON FAIT PASSER LA MATIERE EN CONTINU D'UNE ETAPE DE LAVAGE A LA SUIVANTE DANS DES ZONES DE TRAITEMENT SUCCESSIVES D'UN MEME APPAREIL PLACEES L'UNE APRES L'AUTRE LE LONG D'UNE DIRECTION LONGITUDINALE D'AVANCEMENT DANS, CHAQUE ZONE DE TRAITEMENT, LA MATIERE EST DILUEE AVEC UN LIQUIDE DE LAVAGE INJECTE EN AMONT DE LA ZONE ET SOUMISE A UN MALAXAGE SIMULTANE, PUIS A UNE COMPRESSION PROGRESSIVE DANS LE SENS LONGITUDINAL D'AVANCEMENT, SE TERMINANT PAR UN ESSORAGE EFFECTUE PENDANT LE PASSAGE DANS LA ZONE DE TRAITEMENT SUIVANTE, LA PHASE LIQUIDE ET LES RESIDUS A ELIMINER ETANT EXTRAITS PAR LA COMPRESSION PROGRESSIVE ET PAR L'ESSORAGE ET EVACUES PAR UNE FILTRATION EFFECTUEE DANS LA ZONE DE COMPRESSION DANS UNE DIRECTION TRANSVERSALE A LA DIRECTION.THE OBJECT OF THE INVENTION IS A PERFECTIONED INSTALLATION AND A PROCESS FOR PREPARING A PAPER PULP FROM A LIGNOCELLULOSIC MATERIAL REDUCED TO PIECES AND PREVIOUSLY IMPREGNATED WITH A REAGENT THEN ELIMINATED BY WASHING CARRIED OUT PROGRESSIVELY BY A SERIES OF STEPS FOLLOWING , DILUTION AND FILTRATION. ACCORDING TO THE INVENTION, THE MATERIAL IS CONTINUOUSLY PASSED FROM ONE WASHING STEP TO THE NEXT IN SUCCESSIVE TREATMENT ZONES OF THE SAME APPLIANCE PLACED ONE AFTER THE OTHER ALONG A LONGITUDINAL DIRECTION D 'ADVANCEMENT IN EACH TREATMENT ZONE, THE MATERIAL IS DILUTED WITH A WASHING LIQUID INJECTED UPSTREAM OF THE ZONE AND SUBJECTED TO SIMULTANEOUS MIXING, THEN TO A PROGRESSIVE COMPRESSION IN THE LONGITUDINAL DIRECTION OF ADVANCEMENT, ENDING WITH A SPIN PERFORMED DURING THE PASSAGE THROUGH THE FOLLOWING TREATMENT ZONE, THE LIQUID PHASE AND THE RESIDUES TO BE ELIMINATED BEING EXTRACTED BY PROGRESSIVE COMPRESSION AND BY SPIN AND REMOVED BY FILTRATION CARRIED OUT IN THE COMPRESSION ZONE IN A DIRECTION TRANSVERSAL TO THE DIRECTION.
