Title
(DE) VERFAHREN UND VORRICHTUNG ZUM RECYCLING VON WERTMETALLHALTIGEN ABFALLSTOFFEN
(EN) METHOD AND DEVICE FOR RECYCLING WASTE MATERIALS CONTAINING VALUABLE METALS
(FR) PROCÉDÉ ET DISPOSITIF DE RECYCLAGE DE DÉCHETS CONTENANT DES MÉTAUX DE VALEUR
Abstract
(DE) Die Erfindung betrifft Verfahren zum Recycling von wertmetallhaltigen Abfallstoffen in einem Wirbelschichtofen (100), umfassend die Phasen I, Anfahren des Wirbelschichtofens; und II Kontinuierliche Wiederaufbereitung der wertmetallhaltigen Abfallstoffe, dadurch gekennzeichnet, dass der Wirbelschichtofen (100) während der Phase II der kontinuierlichen Wiederaufbereitung der wertmetallhaltigen Abfallstoffe autotherm betrieben wird, wobei die Prozesstemperatur über den Füllstand des Wirbelschichtofens (100) und den Materialdurchfluss geregelt wird. Die Erfindung stellt weiterhin eine Vorrichtung, umfassend einen Wirbelschichtofen (100) zum Recycling von wertmetallhaltigen Abfallstoffen in einem kontinuierlichen autothermen Verfahren bereit.
(EN) The invention relates to a method for recycling waste materials containing valuable metals in a fluidised bed furnace (100), comprising the phases I, starting up the fluidised bed furnace; and II continuously reprocessing the waste materials containing valuable metals, characterised in that the fluidised bed furnace (100) is operated autothermally during phase II of the continuous reprocessing of the waste materials containing valuable metals, the process temperature being controlled by means of the fill level of the fluidised bed furnace (100) and the material through-flow. The invention also relates to a device, comprising a fluidised bed furnace (100) for recycling waste materials containing valuable metals in a continuous autothermal method.
(FR) L'invention concerne un procédé de recyclage de déchets contenant des métaux de valeur dans un four à lit fluidisé (100), comprenant les phases I, à partir du four à lit fluidisé ; et II) à traiter en continu les déchets contenant des métaux de valeur, caractérisé en ce que le four à lit fluidisé (100) est actionné autothermiquement pendant la phase II du retraitement continu des déchets contenant des métaux de valeur, la température de traitement étant régulée au moyen du niveau de remplissage du four à lit fluidisé (100) et le flux de matériau à travers l'écoulement. L'invention concerne également un dispositif comprenant un four à lit fluidisé pour le recyclage de déchets contenant des métaux de valeur dans un procédé autothermique continu.
