Abstract

The invention relates to a high-pressure reaction system. The high-pressure reaction system comprises a high-pressure reactor provided with a first feeding port and a liquid phase discharge port; a feeding cylinder which comprises a feeding cylinder feeding port provided with a first valve, and a feeding cylinder discharging port connected with the first feeding port, wherein a second valve is arranged between the first feeding port and the feeding cylinder discharging port; a discharging cylinder which comprises a second discharging port connected with the liquid phase discharging port and adischarging cylinder discharging port provided with a fourth valve, wherein a third valve is arranged between the liquid phase discharging port and the second discharging port; and an oil hydraulic pump which is connected with the feeding cylinder. According to the high-pressure reaction system, scientific arrangement on valves relating to the feeding cylinder and the discharging cylinder is adopted. The invention also provides efficient energy recovery feeding and discharging process of the high-pressure reaction system; under assisting of pressure provided by the oil hydraulic pump, intermittent feeding and discharging or continuous feeding and discharging are achieved, energy can be fully utilized, the circulation rate of materials in the system can be reduced, and power consumption isreduced.
