Abstract

Cette invention consiste à cuire telle quelle la carcasse entière d'un véhicule à moteur mis à la ferraille et dont on a retiré les pièces de valeur ainsi que matières dangereuses. L'élimination du câblage électrique de la carcasse du véhicule en est ainsi facilitée, tandis que les métaux sont récupérés sous forme de ferraille sans entraîner la formation de poussière non métallique due au broyage. Les résidus de la décomposition thermique, qui ont été séparés lors de la cuisson de la carcasse du véhicule, sont ensuite soumis à un traitement thermique sous vide et à haute température. La dioxine décomposée et les métaux lourds présents dans les résidus de décomposition thermique peuvent ainsi être récupérés dans un système d'évacuation sous vide, ceci de manière à pouvoir récupérer la ferraille et le carbone issu de la décomposition thermique. La poussière issue du broyage de la carcasse du véhicule est ensuite cuite en vue de sa décomposition thermique dans des conditions où l'apport en oxygène est aussi réduit que possible. Les solides restants sont réchauffés à une température allant de 400 à 500° C et à une pression réduite, ce qui permet d'éviter que la dioxine et les métaux lourds ne se mélangent aux résidus de la décomposition thermique.
