Abstract

L'INVENTION CONCERNE UN PROCEDE POUR ELIMINER LES OXYDES DE SOUFRE DES GAZ D'ECHAPPEMENT CHAUDS PRODUITS LORS DE LA FABRICATION DE NODULES DE FER REDUITS. DANS UN SYSTEME COMPORTANT UN FOUR DE PRETRAITEMENT CONSTITUE D'UNE ZONE DE SECHAGE 2, D'UNE ZONE DE PRECHAUFFAGE 3 ET D'UNE ZONE DE DURCISSEMENT 4 QUE TRAVERSE UNE GRILLE MOBILE 1, ET UN FOUR ROTATIF 5 RECEVANT LA MATIERE QUITTANT LA ZONE DE DURCISSEMENT, ON INTRODUIT PAR L'ENTREE DE LA GRILLE MOBILE DES NODULES CRUS 8 A TENEUR ELEVEE EN OXYDES DE SOUFRE ET UN AGENT DE DESULFURATION SOLIDE POUR LES FAIRE PASSER A TRAVERS LES ZONES SUCCESSIVES, PUIS DANS LE FOUR ROTATIF OU ON REDUIT LES NODULES, TANDIS QUE L'ON FAIT PASSER LES GAZ D'ECHAPPEMENT CHAUDS DU FOUR ROTATIF DANS UNE DIRECTION OPPOSEE POUR QUE L'AGENT DE DESULFURATION PRECHAUFFE EN ABSORBE DE FACON SATISFAISANTE LES OXYDES DE SOUFRE. L'INVENTION S'APPLIQUE EN PARTICULIER A L'ELIMINATION EFFICACE SIMPLE ET PEU COUTEUSE DES OXYDES DE SOUFRE DES GAZ D'ECHAPPEMENT CHAUDS DE LA FABRICATION DES NODULES DE FER REDUITS.
