Title (EN) METHOD AND PLANT FOR PRODUCING ACTIVE FORMED COKE AS GRANULATE ON THE BASIS OF PRETREATED PIT COAL
(FR) PROCEDE ET INSTALLATION DE FABRICATION DE COKE MOULE ACTIF EN TANT QUE GRANULAT SUR LA BASE DE HOUILLE PRETRAITEE
Abstract:
(EN) The process for producing active formed coke as granulate on the basis of pretreated pit coal provides to pass the preformed granulate through different treatment areas of a shaft (1) and to expose it along its path to a burning and activating process, as well as to a further treatment. The granulates are fed in plane heaps adapted to the cross-section of the shaft and have the same thickness with respect to the cross-section of the latter; they are supported in stages by grates (2) with free intervals therebetween. By maintaining predetermined dwelling times in the various stages, the heaps traverse the treatment areas and the shaft from top to bottom. In the treatment areas, they are traversed by gases or vapours (31) introduced sideways in the intervals separating adjacent heaps. The passage of the heaps from one grate to the other is effected by a regulated motion taking out at least partially grate bars (15, 16) from the grate plane, so that the granulates form again on the following grate a heap having the same thickness with respect to the cross-section.
(FR) Le procédé de fabrication de coke moulé actif en tant que granulat sur la base de houille prétraitée prévoit de faire passer le granulat prémoulé par différentes zones de traitement d'un puits (1) et de l'exposer sur le parcours au procédé de carbonisation et d'activation, ainsi qu'à un traitement ultérieur. Les granulats sont amenés en tas plats adaptés à la section transversale du puits et de même épaisseur par rapport à la section transversale de celui-ci, ils sont soutenus en étages par des grilles (2) avec des intervalles libres entre elles. En maintenant des temps de séjour prédéterminés dans les divers étages, les tas traversent les zones de traitement et le puits de haut en bas. Dans les zones de traitement, ils sont traversés par des gaz ou vapeurs (31) introduits latéralement dans les intervalles séparant des tas voisins. Le passage des tas d'une grille à l'autre est effectué grâce à un mouvement régulé sortant au moins une partie des barreaux de grille (15,16) du plan de la grille, de telle manière que les granulats reforment sur la grille suivante un tas de même épaisseur par rapport à la section transversale.
