PROBLEM TO BE SOLVED: To provide a system capable of achieving a prescribed chemical reaction by maintaining stable high pressure and high temperature.SOLUTION: A high-temperature high-pressure reaction system is provided with a discharge mechanism 20 for discharging in the atmosphere, a treated fluid reacted in a reactor 2 which receives the fluid to be treated and performs a chemical reaction at high temperature under high pressure. In order to compose the discharge mechanism, at least two sets of a discharge device 30 comprising a pair of shut-off valves 25 and the fluid pressure cylinders 21 and 22 connecting to the respective shut-off valves 25 are provided. Further, there is provided a pressurizing unit 27 for pressing a freely-slidable piston 26 provided to the cylinders 21 and 22 to pressurize the treated fluid-housing space in the cylinders 21 and 22. The pressurizing force by the pressurizing unit 27 is set lower than that of a high-pressure pump P for feeding the fluid to be treated and higher than the reaction set pressure in the reactor 2 at a prescribed temperature. Besides, the reaction system is provided with a mechanism 31 for controlling the discharge of the treated fluid, switching the receiving and discharging shut-off valves 23 and 24 to open and close reversely to each other, and selectively opening and closing the receiving shut-off valve 23. |
