Description

Technical Field

[0001] The invention relates to the technical field of gas injection, in particular to a carbon dioxide gas-liquid combined mixed injection structure and a use method thereof. Background Art

[0002] High-pressure liquid CO2 absorbs heat and does work through gasification and expansion, releasing pressure energy, driving water movement and impacting turbines to achieve power generation. It is green and environmentally friendly, simple to install, low cost, safe and reliable, and can achieve good energy-saving and carbon-reduction effects in key carbon-emitting enterprises such as steel, metallurgy, and chemical industry.

[0003] For the energy storage type high-pressure CO2 power generation system that recycles the waste heat of industrial circulating water, the system not only realizes thermoelectric conversion in an environment of 100 to 40°C, thereby broadening the range of waste heat resources that can be used for power generation, but also uses its working mode to provide a new industrial circulating water cooling method, solving problems such as water loss, pollution discharge, greenhouse gas emissions, energy conservation, renewable energy utilization, carbon cycle, etc.

[0004] In practical applications, the endothermic expansion of liquid carbon dioxide usually involves pumping both liquid and gaseous carbon dioxide into the power tank at the same time. The two are not fused, resulting in low efficiency in the endothermic expansion of the liquid carbon dioxide. In addition, the gaseous and liquid carbon dioxide remain in a continuous delivery state. When the amount of liquid carbon dioxide reaches a certain value, a burst expansion will occur, causing the pressure in the power tank to be too high, which may lead to problems such as damage to the power tank.

A guiding groove is formed on the receiving rod. A movable disk is slidably installed on the receiving rod. Second limiting blocks slidably fitted with the guiding groove are arranged on the inner wall of the movable disk. A first spring abutting against the movable disk is sleeved on the receiving rod. A guiding assembly connected to the receiving rod is arranged inside the hollow tube.

[0017] As a further solution of the present invention: The guiding assembly includes support sleeves installed symmetrically inside the hollow tube. A support rod is slidably installed inside the support sleeve. A sealing disk is arranged at the end of the support rod. The sealing disk is slidably connected to the receiving rod. A communication structure connected to the movable disk is arranged on the sealing disk.

[0018] As a further solution of the present invention: The connection structure includes a plurality of first conduction grooves opened on the sealing disc and evenly distributed at equal circumferential intervals. A plurality of second conduction grooves and atomization holes are opened on the movable disc and evenly distributed at equal circumferential intervals. The second conduction grooves are in conduction cooperation with the first conduction grooves, and the atomization holes are in mutual conduction with the second conduction grooves.

[0019] As a further solution of the present invention: The conduction control mechanism includes a fixing plate installed in the reaction tank. A rotating rod is rotatably installed on the fixing plate. The rotating rod is slidably connected to the follower disc. A guiding groove is opened on the rotating rod, and a guiding component connected to the rotating rod is arranged in the conduction pipe.

[0020] As a further solution of the present invention: The guiding component includes second guiding columns installed symmetrically in the conduction pipe. A supporting disc slidably connected to the rotating rod is slidably installed on the second guiding columns. The supporting disc is rotatably connected to the follower disc. A fourth limiting block slidably fitted with the guiding groove is arranged on the inner wall of the supporting disc.

[0022] It further includes a second spring sleeved on the second guiding columns. Two ends of the second spring are respectively abutted against the guiding plate and the supporting disc. A third spring abutted against the guiding plate is sleeved on the rotating rod.

[0023] A usage method of a mixed injection structure combining carbon dioxide gas and liquid includes the following steps:

[0024] Step 1: The dual-material pumping mechanism alternately conveys liquid carbon dioxide and gaseous carbon dioxide into the hollow tube through the piston cylinder in sequence;

[0025] Step 2: Along with the pressure change in the hollow tube, the pressurization atomization mechanism is driven to move, so as to atomize the carbon dioxide mixture of gas and liquid and then convey it into the reaction tank;

[0026] Step 3: The carbon dioxide mixture of gas and liquid will expand and gasify in the reaction tank, so that the pressure in the reaction tank and the conduction pipe gradually increases, so as to drive the conduction control mechanism to move;

[0027] Step 4: Under the action of the conduction control mechanism, control the movement of the follower rotation assembly, so that when the pressure in the conduction pipe reaches a certain value, control the second discharge hole to conduct through the conduction control mechanism, and discharge the gas in the reaction tank through the discharge pipe.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: This application can pump gaseous and liquid carbon dioxide into the hollow pipe in an alternating pumping manner for mixing and then atomizing and transporting it into the reaction tank for reaction. Specifically, under the action of the dual-material pumping mechanism, gaseous and liquid carbon dioxide are pumped into the hollow pipe in sequence, and when the air pressure in the hollow pipe changes, the pressurization atomization mechanism is automatically controlled to move, so that the hollow pipe is conducted, and the mixed gaseous and liquid carbon dioxide is atomized and then transported into the reaction tank. When gaseous and liquid carbon dioxide are alternately added into the hollow pipe, the gaseous and liquid carbon dioxide can be mixed with each other. At the same time, the atomized carbon dioxide can enter the reaction tank more uniformly, and the atomized carbon dioxide can absorb heat and expand more quickly, thereby accelerating the rate of energy conversion.

[0029] As the carbon dioxide in the reaction tank absorbs heat and expands, the pressure in the reaction tank and the conduction pipe will increase. Under the action of the air pressure, drive the conduction control mechanism and the follower rotation assembly to move, and when the air pressure reaches the set range, the conduction control mechanism controls the second discharge hole to conduct, so as to discharge the high-pressure gas through the discharge pipe. The conduction and closing of the second discharge hole can be controlled through the conduction control mechanism and the follower rotation assembly, so as to realize the adjustment of the conduction amount according to the pressure in the reaction tank to ensure that the pressure of the gas discharge is within the set range. At the same time, when gaseous and liquid carbon dioxide are no longer added into the reaction tank, the residual carbon dioxide in the reaction tank can be automatically discharged, and the conduction pipe is blocked again to prevent the residual carbon dioxide from not being discharged, resulting in the problem that the reaction tank is always in a high-pressure state and the service life of the reaction tank is reduced. At the same time, because the atomized carbon dioxide automatically absorbs heat and expands, there is no need to pump it through a power pump, thereby achieving the purpose of reducing energy consumption.

[0045] See also Figures 1 to 12 In an embodiment of the present invention, a carbon dioxide gas-liquid combination mixed ejection structure comprises:

[0046] A reaction tank 1, and a hollow tube 2 and a conducting tube 4 installed at both ends of the reaction tank 1, wherein one end of the conducting tube 4 away from the reaction tank 1 is connected to a discharge pipe 5;

[0047] Also includes:

[0048] See also Figures 1 - 3 ,Figures 5 - 7 A piston cylinder 3 is installed at the end of the hollow tube 2. A dual-material pumping mechanism connected to the hollow tube 2 is provided inside the piston cylinder 3. The dual-material pumping mechanism can transport the material inside the piston cylinder 3 into the hollow tube 2 to adjust the pressure inside the hollow tube 2. The dual-material pumping mechanism includes a motor 6 installed at the end of the piston cylinder 3. A transmission rod 7 connected to the output shaft of the motor 6 is rotatably installed inside the piston cylinder 3. Annular grooves 701 and first spiral grooves 702 are symmetrically arranged on the transmission rod 7. The end of the first spiral groove 702 is connected to the annular groove 701. A conveying assembly connected to the transmission rod 7 is provided inside the piston cylinder 3. Among them, the conveying assembly includes first guide columns 9 installed symmetrically inside the piston cylinder 3. A piston disk 8 slidably connected to the transmission rod 7 is slidably installed on the first guide columns 9. A first limiting block 801 slidably engaged with the annular groove 701 and the first spiral groove 702 is provided on the inner wall of the piston disk 8. An inlet pipe 301, a first feeding pipe 302, and a second feeding pipe 303 are also connected to the circumferential outer wall of the piston cylinder 3. The first feeding pipe 302 and the second feeding pipe 303 are connected to the hollow tube 2.

[0049] Specifically, there are two symmetrically arranged inlet pipes 301. One of the inlet pipes 301 is used to transport liquid carbon dioxide, and the other inlet pipe 301 is used to transport gaseous carbon dioxide. The first feeding pipe 302 is used to transport the liquid carbon dioxide inside the piston cylinder 3 into the hollow tube 2, and the second feeding pipe 303 is used to transport the gaseous carbon dioxide inside the piston cylinder 3 into the hollow tube 2. There are two sets of symmetrically arranged annular grooves 701 and first spiral grooves 702, and the circumferential angle of the annular groove 701 is 90°. The number of spiral turns of the first spiral groove 702 is one-fourth of a turn. The piston disk 8 divides the piston cylinder 3 into two spaces. One of the spaces is connected to one of the inlet pipes 301 and the first feeding pipe 302, and the other space is connected to the other inlet pipe 301 and the second feeding pipe 303. A plurality of one-way valves are provided on the piston cylinder 3 and are respectively connected to the inlet pipe 301, the first feeding pipe 302, and the second feeding pipe 303, so that the material inside the piston cylinder 3 can only enter the piston cylinder 3 through the inlet pipe 301 and be discharged through the first feeding pipe 302 or the second feeding pipe 303.

[0050] Specifically, in the initial state, the piston disk 8 is located at the connection position of one of the annular grooves 701 and the first spiral groove 702. At this time, the piston disk 8 is at the end of the stroke in the direction away from the first feed pipe 302, so that the piston cylinder 3 is filled with liquid carbon dioxide. When the motor 6 operates, it drives the transmission rod 7 to rotate, thereby driving the annular groove 701 and the first spiral groove 702 to move. At this time, the first limit block 801 will disengage from the annular groove 701 and enter the first spiral groove 702, causing the piston disk 8 to move. The piston disk 8 will move along the length direction of the first guide post 9. Since the first guide post 9 has a guiding function, it can ensure that the piston disk 8 does not rotate with the transmission rod 7 during movement. Under the action of the piston disk 8, the liquid carbon dioxide in the piston cylinder 3 is pumped into the hollow tube 2 through the first feed pipe 302. At the same time, under the action of the piston disk 8, gaseous carbon dioxide is inhaled into the space on one side of the second feed pipe 303 through the feed pipe 301. When the first limit block 801 disengages from the first spiral groove 702 and moves into another annular groove 701, the piston disk 8 moves to the end of the stroke, and the pumping of liquid carbon dioxide is completed. At this time, the first limit block 801 will slide in the annular groove 701 until the first limit block 801 disengages from the annular groove 701 and enters another first spiral groove 702. The piston disk 8 will move towards the initial position and pump the gaseous carbon dioxide in the piston cylinder 3 into the hollow tube 2 through the second feed pipe 303. At the same time, liquid carbon dioxide is inhaled into the space on one side of the first feed pipe 302 through the feed pipe 301. When the first limit block 801 is reset, the pumping of gaseous carbon dioxide is completed. Repeat the above steps to achieve continuous and alternating pumping of gaseous and liquid carbon dioxide.

[0051] Please refer to Figures 3 - 6 , Figure 8, A pressure-boosting atomization mechanism is arranged inside the hollow tube 2. The pressure-boosting atomization mechanism can act when the pressure inside the hollow tube 2 changes to adjust the conduction state between the hollow tube 2 and the reaction tank 1. The pressure-boosting atomization mechanism includes a receiving rod 10 installed inside the hollow tube 2. A guiding groove is formed on the receiving rod 10. A movable disk 14 is slidably installed on the receiving rod 10. A second limiting block 1403 that is slidably engaged with the guiding groove is arranged on the inner wall of the movable disk 14. A first spring 15 that abuts against the movable disk 14 is sleeved on the receiving rod 10. A guiding component connected to the receiving rod 10 is arranged inside the hollow tube 2. Among them, the guiding component includes support sleeves 11 that are installed inside the hollow tube 2 and are symmetrically arranged. A support rod 12 is slidably installed inside the support sleeve 11. A sealing disk 13 is arranged at the end of the support rod 12. The sealing disk 13 is slidably connected to the receiving rod 10. A communication structure connected to the movable disk 14 is arranged on the sealing disk 13. The above-mentioned communication structure includes a plurality of first conduction grooves 1301 that are formed on the sealing disk 13 and are equidistantly distributed in a circumferential manner. A plurality of second conduction grooves 1401 and atomization holes 1402 that are equidistantly distributed in a circumferential manner are formed on the movable disk 14. The second conduction grooves 1401 are in conduction cooperation with the first conduction grooves 1301. The atomization holes 1402 are in mutual conduction with the second conduction grooves 1401.

[0052] It should be noted that the guiding groove can be divided into four sections, namely a first vertical groove 1001, a first inclined groove 1002, a second vertical groove 1003, and a second inclined groove 1004. The head and tail of the first vertical groove 1001, the first inclined groove 1002, the second vertical groove 1003, and the second inclined groove 1004 are connected to each other in sequence. A one-way valve is arranged at the connection position between the hollow tube 2 and the reaction tank 1, so that the material can only enter the reaction tank 1 through the hollow tube 2. In the initial state, the pressure inside the hollow tube 2 is relatively small, and the first spring 15 is in a compressed state, so that the movable disk 14 and the sealing disk 13 are located at the end of the stroke on the side facing the piston cylinder 3, and the movable disk 14 and the sealing disk 13 are closely attached to each other. Under the action of the movable disk 14, the second limiting block 1403 is located at the connection position between the first vertical groove 1001 and the second inclined groove 1004, and the first conduction groove 1301 and the second conduction groove 1401 are in a misaligned state. Therefore, the hollow tube 2 is in a blocked state. When the piston disk 8 moves, the liquid carbon dioxide in the piston cylinder 3 can be transported to the hollow tube 2 through the first feed pipe 302. At this time, the pressure change inside the hollow tube 2 is relatively small, and the position of the sealing disk 13 will not change.

[0053] After the transportation of liquid carbon dioxide is completed, under the action of the second feed pipe 303, gaseous carbon dioxide is transported into the hollow tube 2, increasing the pressure inside the hollow tube 2. Under the action of the pressure, the sealing disc 13 is pushed to move away from the piston cylinder 3, causing the support rod 12 to move away from the support sleeve 11. Under the action of the support rod 12 and the support sleeve 11, it is ensured that the sealing disc 13 will not rotate. The sealing disc 13 also pushes the movable disc 14 to move and compresses the first spring 15. The movable disc 14 will drive the second limit block 1403 to slide along the first vertical groove 1001. When the second limit block 1403 disengages from the first vertical groove 1001 and enters the first inclined groove 1002, the movable disc 14 will rotate, thereby driving the second conduction groove 1401 to move.

[0054] At this time, the second conduction groove 1401 will move to the position where it is connected to the first conduction groove 1301, enabling the carbon dioxide mixture of gas and liquid to be discharged through the atomization holes 1402 and transported into the reaction tank 1 through the hollow tube 2. When the second limit block 1403 moves to the position where the first inclined groove 1002 is connected to the second vertical groove 1003, the conduction size between the first conduction groove 1301 and the second conduction groove 1401 is the largest. After the gaseous carbon dioxide in the piston cylinder 3 is discharged, the air pressure inside the hollow tube 2 gradually decreases. At this time, the first spring 15 elastically releases and drives the movable disc 14 to move towards the initial position, causing the second limit block 1403 to move along the length direction of the second vertical groove 1003. When the second limit block 1403 disengages from the second vertical groove 1003 and enters the second inclined groove 1004, the movable disc 14 rotates towards the initial angle. When the second limit block 1403 returns to the initial position, the first conduction groove 1301 and the second conduction groove 1401 are misaligned again. By repeating the above steps, the effect of synchronously transporting gaseous and liquid carbon dioxide into the reaction tank 1 is achieved.

[0055] Preferably, when the second limit block 1403 slides along the second vertical groove 1003 and the second inclined groove 1004, since the first limit block 801 is located in the annular groove 701, during the reset process of the movable disc 14, the carbon dioxide in the piston cylinder 3 will not be transported into the hollow tube 2, ensuring that the subsequent carbon dioxide can be smoothly transported into the hollow tube 2. And because the inclination angle of the first inclined groove 1002 is greater than that of the second inclined groove 1004, the rapid mutual conduction between the first conduction groove 1301 and the second conduction groove 1401 can be controlled, and during the reset process of the movable disc 14, the gas inside the hollow tube 2 can be gradually discharged. When gaseous and liquid carbon dioxide are alternately added into the hollow tube 2, the gas and liquid carbon dioxide can be mixed with each other. At the same time, under the action of the atomization holes 1402, the carbon dioxide is atomized, ensuring that the liquid carbon dioxide entering the reaction tank 1 is more uniform, and the atomized carbon dioxide can absorb heat and expand more quickly, thereby accelerating the rate of energy conversion.

[0056] Please refer to Figure 3 and Figures 9 - 12 A conduction control mechanism is provided inside the conduction pipe 4. A follower disk 25 is connected to the conduction control mechanism. A second discharge hole 26 is formed in the follower disk 25. The conduction control mechanism includes a fixed plate 16 installed inside the reaction tank 1. A rotating rod 17 is rotatably installed on the fixed plate 16. The rotating rod 17 is slidably connected to the follower disk 25. A guiding groove is formed in the rotating rod 17. A guiding component connected to the rotating rod 17 is provided inside the conduction pipe 4. Among them, the guiding component includes second guiding columns 21 installed symmetrically inside the conduction pipe 4. A support disk 23 slidably connected to the rotating rod 17 is slidably installed on the second guiding columns 21. The support disk 23 is rotatably connected to the follower disk 25. A fourth limiting block 2301 slidably fitted with the guiding groove is provided on the inner wall of the support disk 23. A first discharge hole 24 communicating and cooperating with the second discharge hole 26 is formed in the support disk 23.

[0057] Furthermore, the guiding groove can be divided into multiple segments, namely a first straight groove 1701, a first arc groove 1702, a second spiral groove 1703, a second arc groove 1704, a second straight groove 1705, and a third arc groove 1706. The head and tail of the first straight groove 1701, the first arc groove 1702, the second spiral groove 1703, the second arc groove 1704, the second straight groove 1705, and the third arc groove 1706 are connected to each other. In the initial state, the pressure inside the reaction tank 1 and the conduction pipe 4 is relatively small. Under the action of the follower rotation assembly, the support disk 23 and the follower disk 25 are located at the end of the stroke towards the reaction tank 1, so that the fourth limiting block 2301 is located at the connecting position of the first straight groove 1701 and the third arc groove 1706. At this time, the first discharge hole 24 and the second discharge hole 26 are in a misaligned state, and the conduction pipe 4 is in a blocked state. A limiting groove is formed on the circumferential outer wall of the rotating rod 17. A limiting rod slidably connected to the limiting groove is provided on the inner wall of the follower disk 25, which can ensure that the follower disk 25 rotates following the rotating rod 17. When the atomized gas-liquid mixed carbon dioxide enters the reaction tank 1, the gas-liquid mixed carbon dioxide will absorb heat and expand, increasing the air pressure inside the reaction tank 1 and the conduction pipe 4.

[0058] Under the action of air pressure, the support disk 23 is pushed to move away from the reaction tank 1 and along the length direction of the second guide post 21. The support disk 23 will also drive the follower disk 25 and the fourth limit block 2301 to move. The fourth limit block 2301 will slide along the first straight groove 1701, thereby driving the follower rotation assembly to move. When the pressure in the conduction pipe 4 reaches the set value, the fourth limit block 2301 will move to the connection position of the first straight groove 1701 and the first arc groove 1702. Under the action of the follower rotation assembly, the control rotating rod 17 rotates, so that the fourth limit block 2301 moves to the connection position of the first arc groove 1702 and the second spiral groove 1703. The rotating rod 17 will also drive the follower disk 25 to move, so as to drive the second discharge hole 26 to move to the conduction position with the first discharge hole 24. At this time, the high-pressure gas in the conduction pipe 4 will be discharged through the discharge pipe 5.

[0059] Preferably, since gaseous and liquid carbon dioxide continuously enters the reaction tank 1 and continuously undergoes endothermic expansion in the reaction tank 1, when discharging the high-pressure gas, the pressure in the reaction tank 1 will decrease. Under the action of the follower rotation mechanism, the fourth limit block 2301 is controlled by the support disk 23 to enter the second spiral groove 1703, so that the follower disk 25 rotates a certain angle towards the initial angle, so as to reduce the conduction size between the first discharge hole 24 and the second discharge hole 26 until the air pressure in the reaction tank 1 is maintained within a certain range. Thus, according to the pressure in the reaction tank 1, the conduction size between the first discharge hole 24 and the second discharge hole 26 is automatically adjusted to ensure that the pressure of the discharged high-pressure gas is within a certain range. If gaseous and liquid carbon dioxide is no longer added to the reaction tank 1, the air pressure in the reaction tank 1 will gradually decrease. Under the action of the follower rotation assembly, the support disk 23 is continuously driven towards the initial position, so as to drive the fourth limit block 2301 to slide in the second spiral groove 1703 until the fourth limit block 2301 moves to the connection position of the second spiral groove 1703 and the second arc groove 1704. Under the action of the follower rotation assembly, the rotating rod 17 rotates, so that the fourth limit block 2301 enters the second straight groove 1705 through the second arc groove 1704. At this time, the conduction size between the first discharge hole 24 and the second discharge hole 26 reaches the maximum again to discharge the gas remaining in the reaction tank 1. When the support disk 23 is reset, the fourth limit block 2301 moves to the connection position of the second straight groove 1705 and the third arc groove 1706.

[0060] At this time, under the action of the follow-up rotation assembly, the control rotating rod 17 is rotated towards the initial angle to reset the fourth limiting block 2301. By controlling the opening and closing of the first discharge hole 24 and the second discharge hole 26, the conduction amount can be adjusted according to the pressure in the reaction tank 1 to ensure that the pressure of the gas discharge is within the set range. At the same time, when the gas-liquid carbon dioxide is no longer added to the reaction tank 1, the residual carbon dioxide in the reaction tank 1 can be automatically discharged, and the conduction pipe 4 is controlled to be blocked again to prevent the residual carbon dioxide from not being discharged, resulting in the problem that the reaction tank 1 is always in a high-pressure state and the service life of the reaction tank 1 is reduced. At the same time, since the atomized carbon dioxide automatically absorbs heat and expands, there is no need to pump it through a power pump, thereby achieving the purpose of reducing energy consumption.

[0061] Please refer to Figure 3 、 Figures 9 - 12 There is also a follow-up rotation assembly arranged in the conduction pipe 4. The follow-up rotation assembly can drive the movement of the follow-up disc 25 through the conduction control mechanism when the pressure in the conduction pipe 4 changes, so as to perform the opening or closing action on the second discharge hole 26. The follow-up rotation assembly includes a third spiral groove 18 opened on the rotating rod 17. A guide plate 19 slidably connected to the rotating rod 17 is slidably installed on the second guide post 21. A third limiting block 1901 slidably engaged with the third spiral groove 18 is arranged on the inner wall of the guide plate 19. It also includes a second spring 20 sleeved on the second guide post 21. The two ends of the second spring 20 are respectively abutted against the guide plate 19 and the support disc 23. A third spring 22 abutting against the guide plate 19 is sleeved on the rotating rod 17.

[0062] Furthermore, the pitch of the third helical groove 18 is smaller than that of the second helical groove 1703. In the initial state, both the third spring 22 and the second spring 20 are in a compressed state, and the elastic potential energy of the second spring 20 is greater than that of the third spring 22, causing the guide plate 19 to be at the end of the stroke on the side away from the discharge pipe 5, the third limit block 1901 to be at the end of the stroke on the side of the third helical groove 18 facing the reaction tank 1, and the support disk 23 to also be at the end of the stroke on the side facing the reaction tank 1. When the pressure in the conduction pipe 4 increases, under the action of the air pressure, the support disk 23 is pushed to move, thereby driving the fourth limit block 2301 to slide along the first straight groove 1701. Under the action of the fourth limit block 2301 and the first straight groove 1701, it is ensured that the rotating rod 17 does not rotate. At this time, the third spring 22 is gradually compressed, and before the support disk 23 crosses the second arc groove 1704, the elastic potential energy of the third spring 22 will exceed that of the second spring 20, and the guide plate 19 has a tendency to move in the direction away from the reaction tank 1. As the support disk 23 continues to move, the elastic potential energy of the third spring 22 continues to increase until the fourth limit block 2301 moves to the connection position between the first straight groove 1701 and the first arc groove 1702.

[0063] At this time, the third spring 22 elastically releases and drives the guide plate 19 to move in the direction away from the support disk 23 to compress the second spring 20. The guide plate 19 also drives the third limit block 1901 to slide along the third helical groove 18, causing the rotating rod 17 to rotate, thereby controlling the fourth limit block 2301 to move to the connection position between the first arc groove 1702 and the second helical groove 1703. At this time, the first discharge hole 24 and the second discharge hole 26 are mutually conducted, and the conduction size is the largest. As the high-pressure gas is discharged, the air pressure in the reaction tank 1 will decrease. At this time, the second spring 20 and the third spring 22 elastically release and drive the guide plate 19 and the support disk 23 to move towards the initial position. Under the action of the third limit block 1901 and the third helical groove 18, the rotating rod 17 rotates in the initial direction by a certain angle, causing the conduction size of the first discharge hole 24 and the second discharge hole 26 to decrease until the air pressure in the reaction tank 1 remains constant, and the fourth limit block 2301 is still in the second helical groove 1703. When the gas-liquid carbon dioxide is no longer added to the reaction tank 1, the air pressure in the reaction tank 1 gradually decreases, and the second spring 20 and the third spring 22 gradually elastically release until the fourth limit block 2301 moves to the connection position between the second helical groove 1703 and the second arc groove 1704, and the support disk 23 cannot continue to move towards the initial position.

[0064] At this time, the elastic potential energy of the third spring 22 is still greater than that of the second spring 20, thus pushing the guide plate 19 to move away from the support disk 23. Under the action of the third limit block 1901 and the third spiral groove 18, the rotating rod 17 rotates again, so that the fourth limit block 2301 enters the second straight groove 1705 along the second arc groove 1704. Under the action of the fourth limit block 2301 and the second straight groove 1705, the rotation of the rotating rod 17 is restricted. At this time, the third spring 22 is elastically released again and drives the support disk 23 to reset. After the support disk 23 is reset, the fourth limit block 2301 is located at the connection position of the second straight groove 1705 and the third arc groove 1706. At this time, the fourth limit block 2301 no longer restricts the rotation of the rotating rod 17, and the elastic potential energy of the third spring 22 is less than that of the second spring 20. Therefore, the second spring 20 is elastically released and drives the guide plate 19 to reset, so as to control the reset of the rotating rod 17 under the action of the third limit block 1901 and the third spiral groove 18, thereby controlling the fourth limit block 2301 to return to the connection position of the first straight groove 1701 and the third arc groove 1706. By the change of the pressure in the reaction tank 1, the compression amounts of the second spring 20 and the third spring 22 can be automatically adjusted, so as to automatically adjust the position of the support disk 23, making the conduction amount between the first discharge hole 24 and the second discharge hole 26 adaptively adjusted. At the same time, after the reaction stops, the support disk 23 can be automatically controlled to reset, and the remaining carbon dioxide gas can be discharged.

[0065] A method for using a mixed ejector structure combining carbon dioxide gas and liquid includes the following steps:

[0066] Step 1: The dual-material pumping mechanism alternately transports liquid carbon dioxide and gaseous carbon dioxide into the hollow tube 2 through the piston cylinder 3 in sequence;

[0067] Step 2: With the change of the pressure in the hollow tube 2, the pressurization and atomization mechanism is driven to move, so as to atomize the carbon dioxide in gas-liquid mixture and transport it into the reaction tank 1;

[0068] Step 3: The carbon dioxide in gas-liquid mixture will expand and gasify in the reaction tank 1, so that the pressure in the reaction tank 1 and the conduction tube 4 gradually increases, driving the conduction control mechanism to move;

[0069] Step 4: Under the action of the conduction control mechanism, the follow-up rotation assembly is controlled to move. When the pressure in the conduction tube 4 reaches a certain value, the second discharge hole 26 is controlled to conduct through the conduction control mechanism, and the gas in the reaction tank 1 is discharged through the discharge pipe 5.
