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.

[0011] As a further solution of the present invention: the connecting structure includes a plurality of first conducting grooves which are opened on the sealing disk and are equidistantly distributed around the circumference, and a plurality of second conducting grooves and atomization holes which are equidistantly distributed around the circumference are opened on the movable disk, the second conducting grooves are in conduction with the first conducting grooves, and the atomization holes are in conduction with the second conducting grooves.

[0015] A method for using a carbon dioxide gas-liquid combined mixed ejection structure comprises the following steps: Step 1: The dual-material pumping mechanism delivers liquid carbon dioxide and gaseous carbon dioxide to the hollow tube alternately through the piston cylinder; Step 2: As the pressure in the hollow tube changes, the pressurized atomization mechanism is driven to move, so as to atomize the gas-liquid mixed carbon dioxide and then transport it to the reaction tank; Step 3: The gas-liquid mixed carbon dioxide will expand and gasify in the reaction tank, causing the pressure in the reaction tank and the conduction pipe to gradually increase, thereby driving the conduction control mechanism to move; Step 4: Under the action of the conduction regulating mechanism, the follower rotating assembly is controlled to move, so that when the pressure in the conduction pipe reaches a certain value, the conduction regulating mechanism is used to control the conduction of the second discharge hole, and the gas in the reaction tank is discharged through the discharge pipe.

[0016] Compared with the prior art, the beneficial effect of the present invention is that the present application can pump gaseous and liquid carbon dioxide into the hollow tube by alternating pumping, so as to mix and then atomize and transport them to the reaction tank for reaction. Specifically, under the action of the double-material pumping mechanism, the gaseous and liquid carbon dioxide are pumped into the hollow tube in sequence, and when the air pressure in the hollow tube changes, the pressurized atomizing mechanism is automatically controlled to move, so that the hollow tube is conductive, and the mixed gaseous and liquid carbon dioxide is atomized and then transported to the reaction tank. When the gaseous and liquid carbon dioxide are alternately added into the hollow tube, 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 evenly, and the atomized carbon dioxide can absorb heat and expand more quickly, thereby accelerating the rate of energy conversion.

[0017] 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 air pressure, the conduction regulating mechanism and the follower rotating component will be driven to move. When the air pressure reaches the set range, the conduction regulating mechanism controls the conduction of the second discharge hole to discharge the high-pressure gas through the discharge pipe. The conduction and closing of the second discharge hole can be controlled by the conduction regulating mechanism and the follower rotating component, so as to adjust 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 is no longer added to the reaction tank, the residual carbon dioxide in the reaction tank can be automatically discharged, and the conduction pipe can be controlled to be blocked again to prevent the residual carbon dioxide from not being discharged, and the reaction tank is always in a high-pressure state, resulting in a reduced service life of the reaction tank. 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.

[0033] See also Figure 1 to Figure 12 In an embodiment of the present invention, a carbon dioxide gas-liquid combination mixed ejection structure comprises: 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; Also includes: See also Figure 1-Figure 3 , Figure 5-Figure 7 , a piston cylinder 3 is installed at the end of the hollow tube 2, and a double-material pumping mechanism connected to the hollow tube 2 is arranged in the piston cylinder 3, and the double-material pumping mechanism can transport the material in the piston cylinder 3 to the hollow tube 2 to adjust the pressure in the hollow tube 2, and the double-material pumping mechanism includes a motor 6 installed at the end of the piston cylinder 3, and a transmission rod 7 connected to the output shaft of the motor 6 is rotatably installed in the piston cylinder 3, and the transmission rod 7 is provided with a symmetrically arranged annular groove 701 and a first spiral groove 702, and the first spiral groove 702 is connected to the end of the annular groove 701. A conveying assembly connected to the transmission rod 7 is arranged in the piston cylinder 3, wherein the conveying assembly includes a first guide column 9 installed in the piston cylinder 3 and symmetrically arranged, a piston disk 8 slidably installed on the first guide column 9 and slidably connected to the transmission rod 7, and the inner wall of the piston disk 8 is provided with a first limit block 801 slidably engaged with the annular groove 701 and the first spiral groove 702; it also includes a feed pipe 301, a first feeding pipe 302, and a second feeding pipe 303 connected to the circumferential outer wall of the piston cylinder 3, and the first feeding pipe 302 and the second feeding pipe 303 are connected to the hollow tube 2.

[0034] In detail, two feeding pipes 301 are symmetrically arranged, one of which is used to transport liquid carbon dioxide, and the other is used to transport gaseous carbon dioxide. The first feeding pipe 302 is used to transport the liquid carbon dioxide in the piston cylinder 3 to the hollow tube 2, and the second feeding pipe 303 is used to transport the gaseous carbon dioxide in the piston cylinder 3 to the hollow tube 2. The annular groove 701 and the first spiral groove 702 are symmetrically arranged in two groups, and the circumferential angle of the annular groove 701 is 90°, and the first spiral groove 702 is symmetrically arranged in two groups. The number of spiral turns is one quarter of a turn, and the piston disk 8 divides the piston cylinder 3 into two spaces, one of which is connected to one of the feed pipes 301 and the first feeding pipe 302, and the other is connected to the other feed pipe 301 and the second feeding pipe 303. A plurality of one-way valves are arranged on the piston cylinder 3, which are respectively connected to the feed pipe 301, the first feeding pipe 302, and the second feeding pipe 303, so that the material in the piston cylinder 3 can only enter the piston cylinder 3 through the feed pipe 301, and be discharged through the first feeding pipe 302 or the second feeding pipe 303.

[0035] Specifically, in the initial state, the piston disc 8 is located at the connection position between one of the annular grooves 701 and the first spiral groove 702. At this time, the piston disc 8 is located at the end of the stroke away from the first feeding pipe 302, so that the piston cylinder 3 is filled with liquid carbon dioxide. When the motor 6 is working, 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 be separated from the annular groove 701 and enter the first spiral groove 702, so that the piston disc 8 moves. The piston disc 8 will move along the length direction of the first guide column 9. Since the first guide column 9 has a guiding function, it can ensure that the piston disc 8 will not rotate with the transmission rod 7 during movement. Under the action of the piston disc 8, the liquid carbon dioxide in the piston cylinder 3 is pumped into the hollow tube 2 through the first feeding pipe 302. At the same time, under the action of the piston disc 8, through The feed pipe 301 sucks gaseous carbon dioxide into the space on one side of the second feeding pipe 303. When the first limit block 801 disengages from the first spiral groove 702 and moves into another annular groove 701, the piston disc 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 disc 8 will move toward the initial position and transport the gaseous carbon dioxide in the piston cylinder 3 to the hollow tube 2 through the second feeding pipe 303. At the same time, the liquid carbon dioxide is sucked into the space on one side of the first feeding 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 alternating pumping of gaseous and liquid carbon dioxide.

[0036] See also Figure 3-Figure 6 , Figure 8 , a pressurized atomization mechanism is arranged in the hollow tube 2, and the pressurized atomization mechanism can be activated when the pressure in the hollow tube 2 changes to adjust the conduction state between the hollow tube 2 and the reaction tank 1. The pressurized atomization mechanism includes a receiving rod 10 installed in the hollow tube 2, and a guide groove is provided on the receiving rod 10. A movable disk 14 is slidably installed on the receiving rod 10, and a second limit block 1403 that is slidably engaged with the guide groove is provided 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, and a guide component connected to the receiving rod 10 is provided in the hollow tube 2, wherein the guide component includes a receiving rod 10 installed in the hollow tube 2 A supporting sleeve 11 is symmetrically arranged, a supporting rod 12 is slidably installed in the supporting sleeve 11, a sealing disk 13 is arranged at the end of the supporting rod 12, the sealing disk 13 is slidably connected to the receiving rod 10, and a connecting structure connected to the movable disk 14 is arranged on the sealing disk 13, the connecting structure mentioned above includes a plurality of first conducting grooves 1301 which are opened on the sealing disk 13 and are equidistantly distributed around the circumference, a plurality of second conducting grooves 1401 and atomization holes 1402 which are equidistantly distributed around the circumference are opened on the movable disk 14, the second conducting grooves 1401 are connected and cooperated with the first conducting grooves 1301, and the atomization holes 1402 are connected with the second conducting grooves 1401.

[0037] It should be noted that the guide groove can be divided into four sections, namely the first vertical groove 1001, the first inclined groove 1002, the second vertical groove 1003, and the second inclined groove 1004, and 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, and a one-way valve is provided 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 in the hollow tube 2 is small, and the first spring 15 is in a compressed state, so that the movable disk 14 and the sealing disk 13 are located toward the movable disk. At the end of the stroke on one side of the piston cylinder 3, the movable disk 14 and the sealing disk 13 are tightly fitted with each other. Under the action of the movable disk 14, the second limit block 1403 is located at the connection position of the first vertical groove 1001 and the second inclined groove 1004, and the first conducting groove 1301 and the second conducting 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 feeding pipe 302. At this time, the pressure change in the hollow tube 2 is small, and the position of the sealing disk 13 will not change.

[0038] When the liquid carbon dioxide is delivered, the gaseous carbon dioxide is delivered to the hollow tube 2 under the action of the second feeding pipe 303, so that the pressure in the hollow tube 2 increases, and under the action of the pressure, the sealing disk 13 is pushed to move in the direction away from the piston cylinder 3, so that the support rod 12 moves in the direction 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 disk 13 does not rotate. The sealing disk 13 will also push the movable disk 14 to move and compress the first spring 15. The movable disk 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 disk 14 will rotate, thereby driving the second conducting groove 1401 to move.

[0039] At this time, the second conducting groove 1401 will move to the position connected with the first conducting groove 1301, so that the gas-liquid mixed carbon dioxide is discharged through the atomizing hole 1402 and transported to the reaction tank 1 through the hollow tube 2. When the second limit block 1403 moves to the position connected with the first inclined groove 1002 and the second vertical groove 1003, the conduction size between the first conducting groove 1301 and the second conducting groove 1401 is the largest. When the gaseous carbon dioxide in the piston cylinder 3 is discharged, the air pressure in the hollow tube 2 gradually decreases. At this time, the first spring 15 The movable disk 14 is elastically released and drives the movable disk 14 to move toward the initial position, so that the second limit block 1403 moves 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 disk 14 rotates toward the initial angle. When the second limit block 1403 returns to the initial position, the first conducting groove 1301 is misaligned with the second conducting groove 1401 again, and the above steps are repeated, thereby achieving the effect of synchronously transporting gaseous and liquid carbon dioxide into the reaction tank 1.

[0040] 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 resetting process of the movable disk 14, the carbon dioxide in the piston cylinder 3 will not be transported to the hollow tube 2, ensuring that the subsequent carbon dioxide can be smoothly transported to the hollow tube 2, and since the inclination angle of the first inclined groove 1002 is greater than the inclination angle of the second inclined groove 1004, the first conducting groove 1301 and the second conducting groove 1401 can be controlled to quickly conduct with each other, and during the resetting process of the movable disk 14, the gas in the hollow tube 2 is gradually discharged, and when gaseous and liquid carbon dioxide are alternately added into the hollow tube 2, gaseous and liquid carbon dioxide can be mixed with each other. At the same time, under the action of the atomizing hole 1402, the carbon dioxide is atomized to ensure 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.

[0041] See also Figure 3 , Figure 9-12 , a conduction and regulation mechanism is arranged in the conduction tube 4, a follower disk 25 is connected to the conduction and regulation mechanism, a second discharge hole 26 is provided on the follower disk 25, the conduction and regulation mechanism includes a fixed plate 16 installed in the reaction tank 1, a rotating rod 17 is rotatably installed on the fixed plate 16, the rotating rod 17 is slidably connected with the follower disk 25, a guide groove is provided on the rotating rod 17, a guide assembly connected with the rotating rod 17 is provided in the conduction tube 4, wherein the guide assembly includes a second guide column 21 installed in the conduction tube 4 and symmetrically arranged, a support disk 23 slidably connected with the rotating rod 17 is slidably installed on the second guide column 21, the support disk 23 is rotatably connected with the follower disk 25, a fourth limit block 2301 slidably engaged with the guide groove is provided on the inner wall of the support disk 23, and a first discharge hole 24 conducting and cooperating with the second discharge hole 26 is provided on the support disk 23.

[0042] Further, the guide groove can be divided into multiple sections, namely, 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, and 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 from head to tail. In the initial state, the pressure in the reaction tank 1 and the guide tube 4 is relatively small. Under the action of the follower rotating assembly, the support plate 23 and the follower plate 25 are located toward the reaction tank 1. At the end of the stroke in the direction of rotation, the fourth limit block 2301 is located at the connection 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 dislocated state, the conducting pipe 4 is in a blocked state, a limit groove is provided on the circumferential outer wall of the rotating rod 17, and a limit rod slidably connected to the limit groove is provided on the inner wall of the follower disk 25 to ensure that the follower disk 25 rotates with 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, thereby increasing the air pressure in the reaction tank 1 and the conducting pipe 4.

[0043] Under the action of air pressure, the support plate 23 is pushed to move in the direction away from the reaction tank 1 and move along the length direction of the second guide column 21. The support plate 23 will also drive the follower plate 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 rotating component to move. When the pressure in the conducting pipe 4 reaches the set value, the fourth limit block 2301 will move to the connection position between the first straight groove 1701 and the first arc groove 1702. Under the action of the follower rotating component, the rotating rod 17 is controlled to rotate so that the fourth limit block 2301 moves to the connection position between the first arc groove 1702 and the second spiral groove 1703. The rotating rod 17 will also drive the follower plate 25 to move, so as to drive the second discharge hole 26 to move to the conducting position with the first discharge hole 24. At this time, the high-pressure gas in the conducting pipe 4 will be discharged through the discharge pipe 5.

[0044] Preferably, since the gaseous and liquid carbon dioxide continuously enters the reaction tank 1 and continuously absorbs heat and expands in the reaction tank 1, the pressure in the reaction tank 1 will decrease when the high-pressure gas is discharged. Under the action of the follower rotating 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 toward the initial angle to reduce the conduction size of the first discharge hole 24 and the second discharge hole 26 until the gas pressure in the reaction tank 1 is maintained within a certain range, thereby automatically adjusting the conduction size of the first discharge hole 24 and the second discharge hole 26 according to the pressure in the reaction tank 1, ensuring that the pressure of the discharged high-pressure gas is within a certain range. If the gaseous and liquid carbon dioxide is no longer added to the reaction tank 1, the reaction tank 1 will be The air pressure in the tank 1 will gradually decrease. Under the action of the follow-up rotating component, the support plate 23 will continue to move toward the initial position 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 follow-up rotating component, the rotating rod 17 rotates to allow the fourth limit block 2301 to enter the second straight groove 1705 through the second arc groove 1704. At this time, the conduction size of 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 plate 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.

[0045] At this time, under the action of the follow-up rotating component, the rotating rod 17 is controlled to rotate toward the initial angle to reset the fourth limit block 2301. By controlling the conduction 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 gaseous and 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 conducting pipe 4 can be controlled to be blocked again to prevent the residual carbon dioxide from not being discharged, and the reaction tank 1 is always in a high-pressure state, resulting in a problem of reduced service life of the reaction tank 1. 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.

[0046] See also Figure 3 , Figure 9-12 , a follow-up rotating assembly is also provided in the conduction pipe 4, and the follow-up rotating assembly can drive the follow-up disk 25 to move through the conduction regulating mechanism when the pressure in the conduction pipe 4 changes, so as to perform a conduction or closing action on the second discharge hole 26, and the follow-up rotating assembly includes a third spiral groove 18 opened on the rotating rod 17, and a guide plate 19 slidably connected to the rotating rod 17 is slidably mounted on the second guide column 21, and a third limit block 1901 slidably engaged with the third spiral groove 18 is provided on the inner wall of the guide plate 19; and it also includes a second spring 20 sleeved on the second guide column 21, and the two ends of the second spring 20 are respectively abutted against the guide plate 19 and the support disk 23, and the rotating rod 17 is sleeved with a third spring 22 abutting against the guide plate 19.

[0047] Furthermore, the pitch of the third spiral groove 18 is smaller than the pitch of the second spiral groove 1703. In the initial state, the third spring 22 and the second spring 20 are both in a compressed state, and the elastic potential energy of the second spring 20 is greater than the elastic potential energy of the third spring 22, so that the guide plate 19 is located at the end of the stroke away from the discharge pipe 5, the third limit block 1901 is located at the end of the stroke of the third spiral groove 18 toward the reaction tank 1, and the support plate 23 is also located at the end of the stroke toward the reaction tank 1. When the pressure in the guide pipe 4 increases, the support plate 23 is pushed to move under the action of the air pressure, thereby driving the fourth limit block 230 1 slides along the first straight groove 1701, and 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 plate 23 has not crossed the second arc groove 1704, the elastic potential energy of the third spring 22 will exceed the elastic potential energy of the second spring 20, and the guide plate 19 has a tendency to move away from the reaction tank 1. With the continuous movement of the support plate 23, the elastic potential energy of the third spring 22 continues to increase until the fourth limit block 2301 moves to the connection position of the first straight groove 1701 and the first arc groove 1702.

[0048] At this time, the third spring 22 is elastically released and drives the guide plate 19 to move in a 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 spiral groove 18, so that the rotating rod 17 rotates, thereby controlling the fourth limit block 2301 to move to the connection position of the first arc groove 1702 and the second spiral groove 1703. At this time, the first discharge hole 24 and the second discharge hole 26 are connected to each other, and the connection 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 are elastically released, and drive the guide plate 19 and the support disk 23 to the initial The first and second springs 20 and 22 are gradually released from the first and second arc grooves 1704 until the fourth limit block 2301 moves to the initial position.

[0049] At this time, the elastic potential energy of the third spring 22 is still greater than the elastic potential energy of the second spring 20, thereby pushing the guide plate 19 to move in the direction away from the support plate 23, and 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, and 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 plate 23 to reset. When the support plate 23 is reset, the fourth limit block 2301 is located at the connection position between the second straight groove 1705 and the third arc groove 1706. At this time, the fourth limit block 2301 no longer restricts the rotation The rod 17 rotates, and the elastic potential energy of the third spring 22 is less than the elastic potential energy 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 rotation rod 17 to reset 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. Through the pressure change in the reaction tank 1, the compression amount of the second spring 20 and the third spring 22 can be automatically adjusted, thereby automatically adjusting the position of the support plate 23, so that the conduction amount of the first discharge hole 24 and the second discharge hole 26 can be adaptively adjusted. At the same time, after the reaction stops, the support plate 23 can be automatically controlled to reset and the residual carbon dioxide gas can be discharged.

[0050] A method for using a carbon dioxide gas-liquid combined mixed ejection structure comprises the following steps: Step 1: The dual-material pumping mechanism delivers liquid carbon dioxide and gaseous carbon dioxide to the hollow tube 2 alternately through the piston cylinder 3; Step 2: As the pressure in the hollow tube 2 changes, the pressurized atomization mechanism is driven to move, so as to atomize the gas-liquid mixed carbon dioxide and then transport it to the reaction tank 1; Step 3: The gas-liquid mixed carbon dioxide will expand and gasify in the reaction tank 1, so that the pressure in the reaction tank 1 and the conducting pipe 4 gradually increases, thereby driving the conduction regulating mechanism to move; Step 4: Under the action of the conduction regulating mechanism, the follower rotating assembly is controlled to move, so that when the pressure in the conduction pipe 4 reaches a certain value, the conduction regulating mechanism controls the second discharge hole 26 to be conducted, and the gas in the reaction tank 1 is discharged through the discharge pipe 5.
