Abstract
A safe and efficient hydrothermal reaction apparatus for converting waste plastic into oil is described herein. The apparatus comprises a receiver tank for containing therein a mixture of plastic and water; a high-pressure injection pump in communication with the receiver tank through a flow passage change-over valve, the flow passage change-over valve being in communication with a water injection passage; a reactor device including a curved piping in communication with the injection pump, the curved piping being provided with a heating means; and an effluent tank in communication with the reactor device through a pressure reducing valve. The flow rate of the mixture injected into the reaction device may be controlled by regulating the pressure reducing valve. Thermal decomposition of the mixture is performed in the reactor device under pressure and temperature conditions equal to, or above, a value by which a supercritical condition of water is achieved, and under the turbulent flow conditions generated partly by the curved piping.
