[0045] The bottom of the autoclave 2 is fixedly provided with a support frame 1, which supports the autoclave 2.

[0046] Working principle:

[0047] In use, the liquid material is passed into the autoclave 2 through the feeding hole 22, and the liquid material flows over the fixed cylinder 11. One end of the first gas pipe 5 is connected with the gas to be reacted.

[0048] The valve on the second gas pipe 7 is closed, and the valve on the first gas pipe 5 is opened. The gas pump 4 is started, so that the gas enters the inside of the third gas pipe 8 through the first gas pipe 5, and then enters the inside of the annular pipe 12 and the fourth gas pipes 13, and is discharged through the gas outlets to react with the material in the fixed cylinder 11.

[0049] When more gas is passed in, the gas will move out of the liquid material in the form of bubbles and float to the top of the autoclave 2.

[0050] Close the valve on the first gas pipe 5 and open the valve on the second gas pipe 7. This allows the gas from the top of the autoclave 2 to enter the second gas pipe 7, and then re-enter the fixed cylinder 11 through the third gas pipe 8 to carry out the reaction.

[0051] The motor 3 is started, causing the shaft 9 to rotate, which in turn drives the auger 10 to rotate. The rotation of the auger 10 presses the liquid material downwards, causing it to move downwards inside the fixed cylinder 11, and then flow out of the fixed cylinder 11 through its bottom. Meanwhile, the liquid material at the top of the fixed cylinder 11 is forced into the fixed cylinder 11, thus causing the liquid material to flow inside the autoclave 2, allowing more liquid material to come into contact with the gas, thereby reducing the reaction time.

[0052] After the reaction is complete, the material in the high-pressure reactor 2 is discharged through the discharge pipe.

[0053] Example 2: As Figures 4-6 As shown, an energy-saving gas supply system for a high-pressure reactor includes a high-pressure reactor 2.

[0055] A fixed cylinder 11 is fixedly installed at the bottom of the autoclave 2, and the auger 10 is rotatably installed inside the fixed cylinder 11. The fixed cylinder 11 is gourd-shaped.

[0056] Several support plates are evenly fixedly connected to the bottom surface of the fixed cylinder 11, and the bottom ends of the support plates are fixedly connected to the bottom surface of the inner cavity of the autoclave 2.

[0063] A first one-way valve 20 is arranged on the fifth gas pipe 14. The first one-way valve 20 allows the gas in the piston cylinder 16 to be discharged only through the fifth gas pipe 14. The fifth gas pipe 14 discharges the gas to the ring pipe 12.

[0064] A piston rod 18 is sealingly and slidably connected to the inside of the piston cylinder 16. One end of the piston rod 18 extends to the outside of the piston cylinder 16. A driving assembly is arranged on the rotating shaft 9, which drives the one end of the piston rod 18 to slide in the inside of the piston cylinder 16. The piston cylinder 16 is used for gas extraction or gas discharge by sliding of the piston rod 18.

[0065] The other end of the piston cylinder 16 is fixedly connected with a second gas pipe 7, and the other end of the second gas pipe 7 is fixedly penetrated through the fixed plate 17.

[0066] A second one-way valve 21 is arranged on the second gas pipe 7. The second one-way valve 21 allows the gas in the piston cylinder 16 to enter only through the second gas pipe 7.

[0067] The driving assembly comprises a rotating disc 15 which is an elliptical cylinder. The rotating disc 15 is fixedly sleeved on the rotating shaft 9, and the rotating disc 15 is in abutting sliding fit with one end of the piston rod 18.

[0068] One end of the piston cylinder 16 is fixedly connected with a spring 19, the spring 19 is sleeved on the piston rod 18, and the other end of the spring 19 is fixedly connected to the end of the piston rod 18. The spring 19 abuts the outer surface of the rotating disc 15.

[0069] An inlet hole 22 is formed on the outer side of the top of the autoclave 2, and liquid material is introduced into the autoclave 2 through the inlet hole 22. The top of the autoclave 2 is fixedly connected with an exhaust pipe 6, and the exhaust pipe 6 is provided with a valve. The bottom end of the autoclave 2 is fixedly connected with a discharge pipe.

[0070] The bottom of the autoclave 2 is fixedly provided with a support frame 1, and the support frame 1 supports the autoclave 2.

[0071] Working principle:

[0072] In use, liquid material is introduced into the autoclave 2 through the inlet hole 22, and the liquid material flows over the fixed cylinder 11. One end of the third gas pipe 8 is connected with the gas to be reacted.

[0073] The gas to be reacted enters the inside of the annular pipe 12 and the fourth gas pipe 13 through the third gas pipe 8, and then is discharged through the gas outlet hole to react with the material in the fixed cylinder 11.

[0074] When more gas is introduced, the gas will move out of the liquid material in the form of bubbles and float to the top of the autoclave 2.

[0075] The rotating shaft 9 is driven to rotate by the starting motor 3, and the rotating shaft 9 drives the auger 10 to rotate. The rotation of the auger 10 will press the liquid material downward, so that the liquid material moves downward in the inside of the fixed cylinder 11, and then flows out of the fixed cylinder 11 through the bottom of the fixed cylinder 11. The liquid material at the top of the fixed cylinder 11 is pressed into the fixed cylinder 11, so that the liquid material flows in the inside of the autoclave 2, and more liquid material is contacted with the gas, thereby reducing the reaction time.

[0076] The rotating shaft 9 will also drive the rotating disc 15 to rotate. Since the rotating disc 15 is an elliptical cylinder, when the end of the rotating disc 15 rotates to contact the end of the piston rod 18, the rotating disc 15 will gradually push the piston rod 18 to slide into the inside of the piston cylinder 16 and compress the spring 19. At this time, the gas in the piston cylinder 16 is discharged into the annular pipe 12 through the fifth gas pipe 14, and then into the fixed cylinder 11.

[0077] When the end of the rotating disc 15 rotates away from the end of the piston rod 18, the spring 19 pushes the piston rod 18 to slide the piston rod 18 to the outside of the piston cylinder 16. The end of the piston rod 18 is always in abutting cooperation with the rotating disc 15 under the action of the spring 19. The gas at the top of the autoclave 2 enters the piston cylinder 16 through the second gas pipe 7.

[0078] Further, the piston cylinder 16 is subjected to gas suction and exhaust through the reciprocating sliding of the end of the piston rod 18 in the piston cylinder 16.

[0079] After the reaction is completed, the material in the autoclave 2 is discharged through the discharge pipe.
