Abstract

Cette invention se rapporte à un appareil de récupération de pneus usagés en caoutchouc et d'autres produits en matières polymères au moyen de pyrolyses effectuées en l'absence d'oxygène dans un système connecté à fonctionnement continu. Etant donné que le processus de pyrolyse consiste à exposer des matières hydrocarbonées à des températures pouvant atteindre 900 degrés C environ et qu'il implique un dégraissage en profondeur du noir de carbone qui est un des produits de décomposition, il est nécessaire de prendre particulièrement en compte les problèmes de sécurité et de protection de l'environnement lors de l'analyse et de la détermination des solutions techniques et de la fonctionnalité globale dans toutes les conditions possibles de fonctionnement pour l'appareil dans sa totalité. On parvient généralement à ce résultat en procédant à un séchage et à un préchauffage de la matière entrante par des gaz pauvres en oxygène provenant de l'installation de chauffage destinée au processus de pyrolyse, en choisissant des verrous à inertie autobloquants à fonctionnement sûr au niveau des orifices d'entrée et de sortie du four à pyrolyse légèrement en surpression, relié directement à une section de broyage destinée aux résidus de noir de carbone, qui permet une séparation simultanée de l'armature en acier et des autres produits terminaux solides, et finalement en intégrant tous les éléments coopérants de façon à obtenir un module normalisé hermétique convenant également à des ensembles modulaires permettant des capacités accrues. Il est possible d'effectuer facilement la distribution de tous les produits récupérés - pétrole (environ 40 % en poids du poids initial du pneu), noir de carbone (45%), gaz (10%), ainsi que de l'armature en acier et des autres résidus - à partir de quantités conservées de manière séparée, et ce en minimisant l'intervention manuelle et les perturbations environnementales. Cet appareil permet de traiter à la fois des pneus entiers et des pneus découpés ou fragmentés et d'autres produits de matières polymères. Cet appareil est commandé et contrôlé par un système informatique complet et il est fabriqué sous forme de modules préfabriqués normalisés permettant un entretien rationnel et des livraisons internationales en conteneurs.
