Abstract

L'invention concerne un appareil de traitement de réaction de conversion de craquage et de réduction destiné à des déchets organiques ménagers, l'appareil de traitement comprenant un dispositif de réaction de conversion de craquage et de réduction rotatif fermé (8), et un dispositif de chauffage (16) destiné à chauffer indirectement des matériaux dans ce dernier depuis l'extérieur du dispositif de réaction de conversion de craquage et de réduction rotatif fermé (8). L'ensemble du processus depuis le craquage jusqu'au traitement de gaz adopte un fonctionnement en cycle fermé en vue d'isoler des matériaux organiques de l'air, de sorte que le processus de traitement et l'évacuation soient complètement commandés, que le processus de réaction de matériaux organiques soit stable et que la sortie soit stable. Les matériaux organiques sont agités en continu et chauffés uniformément dans le dispositif de réaction, de sorte que la réaction soit complètement achevée, ce qui permet de maximiser la production de produits de ressources, tels que le gaz combustible et le goudron, et de réduire la génération d'autres produits nocifs. Le système entier réalise un cycle d'énergie, et le système lui-même présente un besoin réduit en carburant fourni extérieurement, ce qui permet de réduire considérablement la consommation d'énergie et les coûts de fonctionnement.
