Title (EN) PROCESS FOR THE DESTRUCTION OF RUBBER-BASED MATERIALS AND AUTOMOBILE FRAGMENTATION RESIDUES
(FR) PROCEDE DE DESTRUCTION DE MATERIAUX ET DE RESIDUS DE DEMOLITION D'AUTOMOBILES A BASE DE CAOUTCHOUC
Abstract:
(EN) A process for the destruction of rubber-based materials and plastic materials, the process employing a metal smelt in a smelt reactor (1), wherein products of the rubber-based material and/or a plastic material are partially fragmented to form product pieces and the fragmented material is then contacted with an iron smelt, where oxygen is supplied to the smelt. The invention is distinguished in that the pieces of said material are supplied to the metal bath (11), that the pieces are substantially or completely retained in the bath (11) under the bath surface (12) until the pieces have been gasified in contact with the smelt and supplied oxygen, that a foaming slag (13) is established on top of the smelt, and that the metal bath is brough into agitation to such a degree that the pieces are drawn down beneath the bath surface (12) by the motion of the smelt.
(FR) L'invention porte sur un procédé de destruction de matériaux à base de caoutchouc et de matières plastiques utilisant un métal en fusion dans un réacteur à fusion (1) dans lequel des produits constitués de matériau à base de caoutchouc et/ou de matières plastiques sont partiellement morcelés pour donner des morceaux desdits produits, ce matériau morcelé étant ensuite mis en contact avec de l'acier en fusion recevant un apport d'oxygène. L'invention se distingue par le fait que, d'une part les morceaux dudit matériau, qui sont amenés dans un bain de métal (11), sont maintenus, dans une large mesure ou complètement, en dessous de la surface (12) du bain jusqu'à ce qu'ils aient été gazéifiés au contact du produit en fusion et de l'oxygène apporté, ce qui se solde par la formation d'un laitier moussant (13) sur le dessus du bain en fusion et que, d'autre part le bain de métal est agité à tel point que les morceaux sont tirés vers le bas sous la surface (12) du bain par le mouvement du produit en fusion.
