Beschreibung
Zusammenfassung:	The invention provides an energy-saving continuous waste plastic cyclic cracking system with high yield and high sealing property. The system is characterized in that a cracking reaction kettle is connected with a superheated steam generating device; a cyclic heating device is arranged on the cracking reaction kettle; a gas inlet and gas outlet of the cyclic heating device are connected with the cracking reaction kettle to form a cyclic heating loop; a screw feeder and a screw slag extractor are respectively connected with a feeding hole and a discharge hole of the cracking reaction kettle; a cooling device, a gas-liquid separation device and a gas storage device are arranged on an exhaust pipeline in sequence; the exhaust pipeline and the cracking reaction kettle form an exhaust circulation loop. The invention also provides a continuous waste plastic cyclic cracking method. The system and the method have the advantages that waste plastics are pyrolyzed by utilizing the method and the generated gases are inpu
