This invention is about an industrial continuous cracking device of plastics. The technical program of this invention is as following: it includes the outer cylinder and the internal cylinder, and the two sides of the internal cylinder are connected with the outer cylinder; at least one of the outer cylinder and the internal cylinder is set with heating mechanism, and the helical ribbon is fixed in the inside of the outer cylinder wall; the transport mechanism is fixed in the internal cylinder, with its direction contrary to the outer cylinder's the feeding direction. The import mechanism of solid state heat carrier, which is between the outer cylinder and the internal cylinder, is fixed on the inlet side of the internal cylinder; the mechanism used for separating the solid state heat carrier and the solid product produced in cracking, is set in the outer cylinder; the outlets of the oil-gas and solid product are set on the outer cylinder. The structures of this invention are simple, and it can reduce the possessive space. Furthermore, when cycling in the cylinder, the solid heat carrier has no heat energy loss, and that can substantially reduce the operation cost of the equipment.

L'invention porte sur un équipement industriel pour le craquage en continu de matière plastique qui comprend un cylindre externe (13) et un cylindre interne (14). Deux extrémités du cylindre interne (14) sont amenées à communiquer avec le cylindre externe (13). Au moins l'un du cylindre interne (14) et du cylindre externe (13) a un dispositif de chauffage. Il y a des filets de vis (16) sur la paroi interne du corps principal du cylindre externe (13). Il y a un transporteur dans le cylindre interne (14), dont la direction de transfert est inverse à la direction de transfert du cylindre externe (13). Un mécanisme de guidage est pourvu à l'extrémité de l'entrée du cylindre interne (14) pour un caloporteur solide entrant dans le cylindre interne (14) à partir du cylindre externe (13). Un mécanisme de séparation (26) est pourvu dans le cylindre externe (13) pour séparer le caloporteur solide d'un produit solide de craquage. Il y a une sortie pour le gaz de pétrole (10) et une sortie pour le produit solide (25) sur le cylindre externe (13). L'appareil a une structure simple et peut réduire l'espace. Il n'y a pas de perte de chaleur et les coûts d'exploitation sont grandement réduits, en raison de la circulation du caloporteur solide dans les cylindres.
