<p>PROBLEM TO BE SOLVED: To provide a device for the conversion treatment of waste plastics into oil, which as a simple structure, can efficiently recover a heavy oil and does not need an installation for exhaust gas measures and impurity removal. SOLUTION: A heat exchanger 12 for cooling a vaporized gas to obtain a liquidized oil is connected to a piping 8 which is the passage of the vaporized gas, and a piping 13 for taking out only the vaporized gas is branched from the midway of the piping 8. A liquid oil tank 15, an oil strainer 16 and a purified oil tank 18 are sequentially and vertically disposed below the heat exchanger 12.</p> |
