Abstract

SYSTEME DE SEPARATION DES SUBSTANCES LIGNEUSES DISSOUTES, DANS L'EAU DE FABRICATION PROVENANT DE LA PRODUCTION DES PANNEAUX DE FIBRES DE BOIS PAR VOIE HUMIDE. CE SYSTEME COMPREND SUCCESSIVEMENT UN PRECHAUFFEUR 1, UN DEFIBRATEUR 2, UN CYCLONE 3, UN DISPOSITIF DE LESSIVAGE 4 ET UN DISPOSITIF DE DESHYDRATATION 5 DE LA PATE DEFIBREE. OR L'EAU DE FABRICATION PROVENANT DU DISPOSITIF DE DESHYDRATATION 5, EST REMISE EN CIRCULATION EN PARTIE VERS LE DEFIBRATEUR 2, ET EN PARTIE VERS UNE INSTALLATION D'EVAPORATION 6 COMPRISE DANS LE SYSTEME, A PARTIR DE LAQUELLE LA VAPEUR D'EAU OBTENUE EST DIRIGEE VERS LE PRECHAUFFEUR 1. CECI FORME AINSI UN CIRCUIT FERME DE CIRCULATION D'EAU EMPRUNTANT DEUX PARCOURS. CE SYSTEME EST DESTINE A ETRE UTILISE DANS LES INSTALLATIONS DE PRODUCTION DE PANNEAUX DE FIBRES DE BOIS.
