Document Type and Number:
WIPO Patent Application WO/2016/147343
Kind Code:
A1
Abstract:
[Problem] To provide a highly economical device for continuously converting plastic into oil, with which it is possible to convert plastic into oil at a high yield and with infrequent maintenance. [Solution] A device for continuously converting plastic into oil is provided with: an inner heating pipe 30 and an outer heating pipe 31 that are cylindrical and are disposed concentrically; and a multilayer heating unit 3 that has a cylindrical first heater 32 disposed on the inner side of the inner heating pipe 30, a cylindrical second heater 33 disposed between the inner heating pipe 30 and the outer heating pipe 31, and a cylindrical third heater 34 disposed on the outer side of the outer heating pipe 31. The device is configured such that when a plastic melt, which is obtained by heating and melting plastic, flows in the inner heating pipe 30, the plastic melt is heated from both sides by the cylindrical first heater 32 and second heater 33, and when the plastic melt flows in the outer heating pipe 31, the plastic melt is heated from both sides by the cylindrical second heater 33 and third heater 34.
