Problems solved by technology

[0003] The current high-pressure reaction system mostly uses regulating valves to discharge and adjust the liquid level. The current production process of feeding and discharging materials is to carry out feeding and discharging under high pressure difference, which makes the valve wear seriously, the service life is short, the discharge energy is all lost, and a large amount of energy is generated at the same time. power consumption

Embodiment 2

[0066] like Figure 1-3 As shown, the difference between the present embodiment and the high-pressure reaction system of Embodiment 1 is that the quantity of the feed cylinder, the discharge cylinder and the hydraulic pump 15 in the present embodiment is two, one feed cylinder, one discharge cylinder and An oil pressure pump 15 connected with the feeding cylinder is a group of feeding and discharging devices, and a high-pressure reactor is respectively connected with two groups of feeding and discharging devices. As shown in the figure, in this embodiment, two sets of feeding and discharging devices are respectively located on the left and right sides of the high pressure reactor.

[0067] The present invention also provides a high-efficiency energy recovery feed-in and discharge process based on the high-pressure reaction system of the present invention, which includes the following steps,

[0068] The two groups of feeding and discharging devices are respectively the first ...

Embodiment 3

[0076] The difference between this embodiment and Embodiment 2 is that in this embodiment, the gas phase outlet 1 of the high-pressure reactor is connected to the second heat exchanger, and the second heat exchanger is connected to the equipment. The second heat exchanger recovers the energy of the gas phase outlet 1 and provides thermal energy and kinetic energy for the connected equipment. Thus, this embodiment further makes full use of system energy and improves the energy utilization rate.
