L'invention concerne un appareil de traitement intelligent sans danger de boues d'hydrocarbures par pyrolyse, comprenant un système de chauffage de boues d'hydrocarbures, un système de transmission pour la pyrolyse de boues d'hydrocarbures, un système d'isolation et de conservation de chaleur et un système de surveillance des données et de contrôle intelligent. Le système de chauffage de boues d'hydrocarbures est installé sur le système de transmission pour la pyrolyse de boues d'hydrocarbures, et est utilisé pour chauffer des boues d'hydrocarbures ; le système de transmission pour la pyrolyse de boues d'hydrocarbures est un système étanche, isolé du système de chauffage des boues d'hydrocarbures, et permet une transmission uniforme et efficace ainsi qu'un chauffage des boues d'hydrocarbures dans différents modes de transmission ; le système d'isolation thermique et de conservation est utilisé pour assurer l'isolation thermique et la conservation du système de chauffage de boues d'hydrocarbures et du système de transmission pour la pyrolyse de boues d'hydrocarbures ; le système intelligent de surveillance de données et de commande est électriquement connecté au système de chauffage de boues d'hydrocarbures et au système de transmission pour la pyrolyse de boues d'hydrocarbures, et est utilisé pour commander avec précision la puissance de chauffage du système de chauffage de boues d'hydrocarbures et une vitesse de transmission du système de transmission pour la pyrolyse de boues d'hydrocarbures. L'invention concerne également un procédé de traitement intelligent sans danger de boues d'hydrocarbures par pyrolyse.
