The inventive method for recovery of tires, mainly waste tires, consists in supplying waste tires to a pyrolysis column, in exposing the tires to the action of variable magnetic field in such a way that they are heated to a temperature of rubber thermal decomposition, in removing volatile products which are formed during the rubber thermal decomposition process, in cooling solid residues of the thermal decomposition products and in removing them from the pyrolysis column, wherein the tires are previously divided into parts which are supplied to the pyrolysis column through a feed port and the tires are inductively heated by means of a magnetic field, the frequency of which ranges from 1 to 1000 kHz. A device for carrying out said method is also disclosed.
L'invention concerne un procédé de recyclage de pneus usés qui consiste à alimenter des pneus usés dans une colonne de pyrolyse, à agir sur eux avec un champ magnétique alternatif pour les porter à la température de décomposition thermique du caoutchouc, à évacuer les produits volatils se formant lors de la décomposition thermique du caoutchouc, à refroidir les résidus durs de la décomposition thermique du caoutchouc et à les évacuer de la colonne de pyrolyse, les pneus étant préalablement séparés en deux parties qui sont ensuite alimentés dans la colonne de pyrolyse via une fenêtre de chargement, et le chauffage par induction des parties depneus s'effectuant par la génération de courants d'induction dans la corde métallique des fragments des pneus avec un champ magnétique possédant une fréquence entre 1 et 1000 KHz. L'invention concerne aussi un dispositif de mise en oeuvre de ce procédé.
