Abstract

Four de fusion d'aluminium pour l'incineration de dechets contenant des metaux utiles tels que de l'aluminium utilisant des pneus au rebut en tant que combustibles pour recuperer l'aluminium contenu dans les dechets. Ce four se compose d'un four de production de gaz possedant une source de combustible constituee par des pneus au rebut, d'une cheminee de reaction de combustion possedant au centre une buse d'injection d'air secondaire, d'un four de fusion d'aluminium possedant a l'interieur un four de support d'aluminium, connecte de maniere sequentielle, des rails etant disposes dans le four pour former une voie de roulement pour un chariot servant a transporter les dechets incineres, ce chariot etant entraine et remorque au moyen d'un moteur et d'une courroie de remorquage. Le chariot possede un corps pourvu de roues et un lit pouvant etre bascule longitudinalement au moyen d'une tige au centre du corps. Le lit est en pente vers le sommet du four de support d'aluminium. Lorsque les dechets sont incineres, l'aluminium en fusion s'ecoule dans le four de support d'aluminium; le chariot est alors entraine vers l'extremite opposee de la voie de roulement ou le lit est bascule, dechargeant les dechets incineres a l'exterieur du dispositif. Tout le procede de fusion de l'aluminium, d'incineration des dechets, de transports et de decharges des residus incineres est ainsi execute sans a-coup et efficacement, ce qui permet d'obtenir un taux de recuperation d'aluminium relativement eleve.
