Abstract

L’invention concerne un procédé de pyrolyse destiné à traiter les déchets de caoutchouc et de plastique et les matériaux contenant des résines. Ledit procédé implique l'utilisation d'un pyrolyseur, le broyage des déchets dans un broyeur dans l'atelier produisant les déchets de caoutchouc et de plastique et leur chargement dans un bac d'alimentation, en introduisant simultanément la charge dans le craqueur du pyrolyseur à l’aide d’un chariot de chargement. Le gaz de combustion de la conduite de gaz se mélange à l’air chaud chauffé par la chambre d’accumulation de chaleur et brûle avec lui ; la chaleur dégagée par la combustion est transférée au craqueur et provoque la pyrolyse de la charge. Au démarrage du système de circulation forcé, le gaz de pyrolyse est amené vers le système de séparation et de récupération de fioul et de gaz dans lequel le gaz de pyrolyse est séparé en fioul et gaz combustible. Le système de séparation et de récupération de fioul et de gaz comporte un séparateur fioul-gaz, un condenseur et un séparateur fioul-eau. Le résidu est amené à l’atelier de noir de carbone après pyrolyse complète de la charge dans le craqueur ; là, le noir de carbone et les déchets acier sont séparés et le procédé de pyrolyse global est terminé.
