摘要： 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.

摘要： A safe and efficient hydrothermal reaction apparatus is described herein. Decomposition or synthesis of object material is performed by the continuous passing of the material through a flow passage of multi-staged reactor units under turbulent flow conditions. The flow passage is formed by a curved or spiral piping. In each reactor unit, a hot plate block is included as a heating unit. The hot plate block and the curved piping are placed in an appropriate thermal contact relationship. A portion of the curved piping is freely supported, so as to accommodate stress caused in the piping under high-temperature/high-pressure conditions. A tank is provided for regulating or controlling the pressure fluctuation within the flow passage which may be caused by solids or powder present or occurring in the flow passage during high-pressure treatment. A portion of object material which has not been decomposed during the high-pressure treatment is again introduced or returned to the reactor for complete decomposition thereof after the addition of more solvent.
摘要翻译：这里描述了一种安全有效的水热反应装置。目标材料的分解或合成是通过在湍流条件下连续通过多级反应器单元的流动通道进行的。流动通道由弯曲或螺旋管道形成。在每个反应器单元中，包括热板块作为加热单元。热板块和弯曲管道放置在适当的热接触关系中。弯曲管道的一部分自由地支撑，以适应在高温/高压条件下在管道中产生的应力。提供一个罐，用于调节或控制流道内的压力波动，这可能是由在高压处理期间存在或发生在流路中的固体或粉末造成的。在加入更多的溶剂之后，将高压处理中尚未分解的物料的一部分再次引入或返回到反应器中以使其完全分解。
