Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide sequestration, and in particular to a pressurized and efficient marine carbon dioxide sequestration device. Background Art

[0002] Ocean storage of carbon dioxide refers to storing captured carbon dioxide in the deep sea or on the seabed and under seabed sediments to isolate it from the atmosphere. To ensure the storage effect of carbon dioxide, the carbon dioxide can be completely dissolved in seawater during the floating process after injection. The injection location of carbon dioxide needs to be at least 500 meters above the seabed. If a certain injection depth is to be reached, an injection device corresponding to the ocean depth needs to be built, which is costly and difficult to implement.

[0003] In this regard, the invention patent with prior art publication number CN116608415A provides a carbon dioxide storage device based on a deep-sea platform. Before the carbon dioxide is injected into the second dissolution site in the ocean, it undergoes multiple dissolutions in the first dissolution site, thereby increasing the dissolution rate of the carbon dioxide injection process by increasing the dissolution path of the carbon dioxide.

[0004] The existing technology uses the method of increasing the dissolution path to make carbon dioxide pass through seawater multiple times before injecting it into the ocean to promote the dissolution of carbon dioxide. However, the seawater pressure environment inside the pipeline is different from the external seawater pressure environment. The dissolution rate of carbon dioxide in the seawater inside the pipeline is far from the dissolution rate in the ocean, and the overall dissolution effect is not significantly improved. Summary of the Invention

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present invention provides a pressurized and efficient marine carbon dioxide storage device, comprising a plurality of pressurized cabins 1 arranged in an array, the pressurized cabin 1 at the head end is connected to an injection pipe 2, and the pressurized cabin 1 at the tail end is connected to an air supply pipe 3, the air injection pipe 2, the plurality of pressurized cabins 1, and the air supply pipe 3 are connected in sequence to form a continuous carbon dioxide transport pipeline.

[0052] The pressurized chamber 1 provides a place for carbon dioxide to dissolve before being injected into the ocean. The pressurized chamber 1 is generally set up in an area close to the carbon dioxide injection location. In order to further improve the dissolution effect, the dissolution rate can also be optimized by adding a pressurized chamber 1.

[0053] A pressurizing sleeve 4 is movably installed on the pressurizing cabin 1, and an inner cavity 5 is formed inside the pressurizing sleeve 4 and the pressurizing cabin 1. The size of the inner cavity 5 changes with the movement of the pressurizing sleeve 4 on the pressurizing cabin 1. When the inner cavity 5 becomes smaller, the internal pressure of the inner cavity 5 increases, which promotes the dissolution of carbon dioxide in seawater.

[0054] The pressurized chamber 1 and the pressurized sleeve 4 are provided with a liquid hole group 6 on their side walls. Seawater enters the inner chamber 5 through the liquid hole group 6. The liquid hole group 6 opens or closes in response to the movement of the pressurized sleeve 4 on the pressurized chamber 1. Before pressurization begins, the liquid hole group 6 is open. After pressurization begins, the liquid hole group 6 is closed.

[0055] The pressurizing sleeve 4 is provided with a push-pull structure 7, which controls the movement of the pressurizing sleeve 4 on the pressurizing cabin 1. When the pressurizing sleeve 4 is pushed toward the pressurizing cabin 1, the liquid hole group 6 is closed and the inner cavity 5 is reduced to pressurize the seawater and carbon dioxide that have entered the inner cavity 5. When the pressurizing sleeve 4 is pulled away from the pressurizing cabin 1, the liquid hole group 6 is opened.

[0056] The two adjacent pressurized cabins 1 are connected to each other through an air duct 8. An opening and closing component 9 is provided in the air duct 8. The opening and closing component 9 controls the opening and closing state of the air duct 8 to close the air duct 8 when the seawater and carbon dioxide in the inner cavity 5 are pressurized, and to open the air duct 8 at other times.

[0057] An inlet 12 and an outlet 13 are respectively provided on the opposite side walls of the pressurized cabin 1. The inlet 12 on the front end of the pressurized cabin 1 is connected to the gas injection pipe 2, and the outlet 13 on the rear end of the pressurized cabin 1 is connected to the gas delivery pipe 3.

[0058] Between adjacent pressurized cabins 1 , one end of the air passage 8 is connected to the outlet 13 of the preceding pressurized cabin 1 , and the other end is connected to the inlet 12 of the following pressurized cabin 1 .

[0059] Taking the internal pressurization process of a pressurized cabin 1 as an example for analysis, the air ducts 8 at the inlet 12 and outlet 13 are closed. At this time, the inner cavity 5 becomes smaller, which can achieve the purpose of pressurizing seawater and carbon dioxide.

[0060] For the pressurized cabin 1 (the first pressurized cabin 1) located at the head end, its inlet 12 is connected to the gas injection pipe 2, and the gas injection pipe 2 itself maintains a downward ventilation state. Under the action of the gas pressure, it can further pressurize the carbon dioxide and seawater inside the inner cavity 5.

[0061] In the present invention, a number of pressurized cabins 1 are arranged between the gas injection pipe 2 and the gas transmission pipe 3. The push-pull structure 7 can drive the movement of the pressurized sleeve 4 to shrink the inner cavity 5, and pressurize the seawater and carbon dioxide that have entered the inner cavity 5. Under a certain pressure environment, the carbon dioxide is directly dissolved in the seawater before being injected into the ocean. The carbon dioxide travels through the several pressurized cabins 1 in sequence along the carbon dioxide transportation pipeline, optimizing the dissolution environment on the basis of increasing the dissolution path, thereby greatly improving the dissolution rate of carbon dioxide.

[0062] If the seawater and carbon dioxide in the inner cavity 5 are pressurized and the seawater has already filled the inner cavity 5, then most of the pressurization action acts on the seawater, which may not provide a good auxiliary effect on the dissolution effect between the carbon dioxide and the seawater. In this regard, the present invention has the following design: when the seawater and carbon dioxide that have entered the inner cavity 5 are pressurized, the seawater does not fill the inner cavity 5, and the carbon dioxide and seawater are in the inner cavity 5. During the continuous pressurization process, a large amount of carbon dioxide in the inner cavity 5 is dissolved in the seawater.

[0063] In practical applications, a certain pressurization cycle can be set. After each pressurization cycle, when the amount of seawater entering the inner cavity 5 reaches a certain amount, pressurization is performed and the injection of seawater is stopped at the same time to achieve the dissolution of carbon dioxide in the seawater.

[0064] To improve the pressure effect, Figure 6 and Figure 8 As shown, the present invention provides two boosting sleeves 4, and they are respectively arranged at opposite positions on the boosting cabin 1. The boosting cabin 1 is hollow, and the opening of one boosting sleeve 4 is opposite to the opening of the other boosting sleeve 4; the two boosting sleeves 4 can approach each other under the action of thrust.

[0065] In the above embodiment, one booster sleeve 4 is arranged above the booster cabin 1, and the other booster sleeve 4 is arranged below the booster cabin 1. When pressurized, the two booster sleeves 4 move in the direction close to the booster cabin 1. The booster sleeves 4 have the same shape and are symmetrically arranged. The design of the two booster sleeves 4 can also limit each other. When the two booster sleeves 4 approach each other until their ends contact each other, they can prevent each other from continuing to move, thereby limiting the booster sleeves 4 and limiting the range of volume change inside the content cavity 5.

[0066] In the present invention, the push-pull structure 7 can control the movement of the booster sleeve 4 on the booster cabin 1. When the booster sleeve 4 is pushed to move toward the booster cabin 1, the liquid hole group 6 is closed and the inner cavity 5 is reduced to pressurize the seawater and carbon dioxide that have entered the inner cavity 5. When the booster sleeve 4 is pulled to move away from the booster cabin 1, the liquid hole group 6 is opened. Specifically, Figure 6 、 Figure 7and Figure 8 As shown, the push-pull structure 7 includes a mounting frame 71, a first slide 72 mounted on one side of the mounting frame 71, and a second slide 73 mounted on the other side of the mounting frame 71;

[0067] The first slide 72 is connected to a first U-shaped push-pull frame 74, and the second slide 73 is connected to a second U-shaped push-pull frame 75. The ends of the first U-shaped push-pull frame 74 and the second U-shaped push-pull frame 75 respectively abut against different booster sleeves 4;

[0068] A rotating shaft 76 is installed at the bottom center of the mounting frame 71, and a rotating frame 77 is rotatably mounted on the rotating shaft 76. A first connecting shaft 78 is installed on the first U-shaped push-pull frame 74, and a first sliding sleeve 79 is rotatably mounted on the first connecting shaft 78. The first sliding sleeve 79 is slidably set on the rotating frame 77.

[0069] A second connecting shaft 710 is mounted on the second U-shaped push-pull frame 75 , a second sliding sleeve 711 is rotatably mounted on the second connecting shaft 710 , and the second sliding sleeve 711 is slidably disposed on the rotating frame 77 ;

[0070] By controlling the movement of the first slide 72 on the mounting frame 71, the first U-shaped push-pull frame 74 is driven to push one of the booster sleeves 4 toward the direction close to the booster cabin 1, and the rotating frame 77 is driven to rotate through the first slide 79, and the second U-shaped push-pull frame 75 is driven through the rotating frame 77 to push the other booster sleeve 4 toward the direction close to the booster cabin 1.

[0071] During the specific implementation process, in the initial state, the booster sleeve 4 is located above and below the booster cabin 1, and the volume of the inner cavity 5 is the largest at this time. The first slide 72 is controlled to move downward on the mounting frame 71, driving the first U-shaped push-pull frame 74 to push one of the booster sleeves 4 toward the direction close to the booster cabin 1. The booster sleeve 4 located above moves downward. During the downward movement of the first U-shaped push-pull frame 74, the first slide 79 drives one side of the rotating frame 77 to rotate downward. At the same time, the first slide also slides along the rotating frame 77. After a short distance, the rotation of the rotating frame 77 drives the other end of the rotating frame 77 to rise, and drives the second U-shaped push-pull frame 75 to move up through the second sliding sleeve 711. The second U-shaped push-pull frame 75 pushes the other booster sleeve 4 toward the direction close to the booster cabin 1, and the booster sleeve 4 located below moves up under the push. In the above process, the booster sleeve 4 located above moves down, and the booster sleeve 4 located below moves up. When they move to the point where the two booster sleeves 4 are against each other, they stop moving. At this time, the volume of the inner cavity 5 changes to the minimum.

[0072] In order to drive the first slide 72 to move up and down on the mounting frame 71 during the above process, the present invention makes the following design: Figure 6As shown, a sleeve 712 is provided in the installation frame 71 , a lifting column 713 is movably mounted on the sleeve 712 , and the lifting column 713 is connected to the first slide 72 ;

[0073] like Figure 1 As shown, the lifting columns 713 corresponding to adjacent pressurized cabins 1 are connected by a connecting frame 714, and the connecting frame 714 is away from the air duct 8 and the pressurized cabin 1;

[0074] Among them, the lifting column 713 corresponding to the pressurized cabin 1 at the head end is connected to a driving shaft 715.

[0075] In the above embodiment, the up and down movement of the lifting columns 713 can be achieved by controlling the up and down movement of the active shaft 715 , thereby driving all the lifting columns 713 to move up and down synchronously through the connecting frame 714 .

[0076] If pressurization is to be implemented according to the periodic principle, the pressurization action needs to be performed after a pressurization cycle, that is, the active shaft 715 is controlled to descend at intervals. If the active shaft 715 is to be automatically periodically moved, a driving structure such as a cylinder can be set on the active shaft 715, and a program can be set to drive the active shaft 715 to perform periodic movement.

[0077] The first U-shaped push-pull frame 74 and the second U-shaped push-pull frame 75 not only push the boost sleeve 4, but also pull it. In order to facilitate the joint pushing and pulling actions, a pressure sleeve 10 is installed on the boost sleeve 4. The ends of the first U-shaped push-pull frame 74 and the second U-shaped push-pull frame 75 extend into the pressure sleeve 10. The pressure sleeve 10 is arranged on the boost sleeve 4 in the shape of an arch bridge. The first U-shaped push-pull frame 74 and the second U-shaped push-pull frame 75 drive the movement of the boost sleeve 4 by pushing and pulling the pressure sleeve 10.

[0078] The ends of the first U-shaped push-pull frame 74 and the second U-shaped push-pull frame 75 extend into the interior of the pressure sleeve 10 .

[0079] In the present invention, the liquid hole group 6 opens or closes following the movement of the pressurizing sleeve 4 on the pressurizing cabin 1. Before pressurization begins, the liquid hole group 6 is in an open state. After pressurization is implemented, the liquid hole group 6 is closed. Specifically, Figure 8 and Figure 9 As shown, the liquid hole group 6 includes a first hole body 61 provided on the side wall of the pressure sleeve 10 located at the bottom, and a second hole body 62 provided on the side wall of the pressurized cabin 1. When the first hole body 61 and the second hole body 62 are positioned at the same position, the inner cavity 5 is connected to the outside. When the first hole body 61 and the second hole body 62 are positioned at the same position, seawater cannot enter the inner cavity 5.

[0080] In the initial state, the volume of the inner cavity 5 is the largest. When the positions of the first hole body 61 and the second hole body 62 coincide, the inner cavity 5 is connected to the outside, and seawater can enter the inner cavity 5 through the first hole body 61 and the second hole body 62. After a certain amount of seawater enters, the pressurization sleeve 4 moves relative to the pressurization cabin 1 to implement pressurization. At the same time, the positions of the first hole body 61 and the second hole body 62 are misaligned. At this time, seawater cannot enter the inner cavity 5, and the inner cavity 5 is in a closed state.

[0081] In order to ensure the closed state of the inner chamber 5 during the pressurization process, the present invention also makes the following designs, such as Figure 5 and Figure 10 As shown, the gas pipe 8 and the gas delivery pipe 3 at least partially form a vertical pipe section 11; the opening and closing assembly 9 includes a valve seat 92 and a valve block 91 provided in the vertical pipe section 11. When the valve block 91 is stuck on the valve seat 92, the vertical pipe section 11 is closed;

[0082] A control rod 93 is provided through the vertical pipe section 11 . The control rod 93 passes through the vertical pipe section 11 and is connected to the valve block 91 in each gas passage 8 .

[0083] By controlling the up and down movement of the control rod 93, the closed state of the valve block 91 and the valve seat 92 can be controlled. In the initial state, the valve block 91 is away from the valve seat 92, the air duct 8 is in an open state, and the gas can flow. When the pressurized cabin 1 is pressurized, the control rod 93 drives the valve block 91 to be stuck on the valve seat 92, and the air duct 8 is closed.

[0084] The movement of the control rod 93 also follows the periodic principle. A driving structure such as a cylinder can be set at the end of the control rod 93, and a program can be set to drive the control rod 93 to perform periodic movement.

[0085] Unlike the active shaft 715, the control rod 93 is not reset after the pressurization is completed, but resets during the pressurization process, dividing the entire pressurization process into an early stage and a late stage. In the early stage of pressurization, the control rod 93 drives the valve block 91 to be stuck on the valve seat 92, and the air pipe 8 is closed. In the late stage of pressurization, the control rod 93 drives the valve block 91 away from the valve seat 92, and the air pipe 8 is opened. In this case, the pressurization action can cause the mixture that has been completely dissolved in the inner chamber 5 to be discharged from the air pipe 8 along the air flow, which means that the pressurization process not only promotes the dissolution of carbon dioxide and seawater, but also promotes the discharge of the mixture after dissolution, so that the next round of new seawater can enter the inner chamber 5 and dissolve with carbon dioxide.

[0086] During the up and down movement, the control rod 93 moves back and forth at the penetration point between the control rod 93 and the vertical pipe section 11 . To prevent gas leakage, a sealing ring is provided at the penetration point between the control rod 93 and the vertical pipe section 11 .

[0087] In addition, it is necessary to ensure that the radius of the control rod 93 is smaller than the minimum aperture of the valve seat 92 to prevent the control rod 93 from blocking the valve seat 92 and causing the problem of being unable to control opening and closing.

[0088] In summary, the main implementation process of the present invention is:

[0089] In the initial state, the volume of the inner chamber 5 is at its maximum. Seawater enters the inner chamber 5 from the first hole 61 and the second hole 62. After a certain amount of seawater is injected into the inner chamber 5, the air passage 8 is closed by controlling the control rod 93. The lifting column 713 is controlled to descend by the active shaft 715, driving the first slide 72 to move downward on the mounting frame 71, driving the first U-shaped push-pull frame 74 to push one of the booster sleeves 4 toward the direction close to the booster cabin 1. The booster sleeve 4 located above moves downward, and the first U-shaped push-pull frame 74 moves downward. During the process, one side of the rotating frame 77 is driven to rotate downward by the first sliding sleeve 79, and the rotation of the rotating frame 77 drives the other end of the rotating frame 77 to rise, and drives the second U-shaped push-pull frame 75 to move upward through the second sliding sleeve 711. The second U-shaped push-pull frame 75 pushes another booster sleeve 4 toward the direction close to the booster cabin 1. The booster sleeve 4 located at the bottom moves upward under the push, and the booster sleeve 4 located at the top moves downward. The booster sleeve 4 located at the bottom moves upward, and the volume of the inner chamber 5 gradually decreases, thereby achieving pressurization of carbon dioxide and seawater.

[0090] Before pressurization is completed, the control rod 93 drives the valve block 91 away from the valve seat 92, and the air passage 8 is opened. In this case, the pressurization action can cause the partially dissolved mixture in the inner chamber 5 to be discharged from the air passage 8 along the air flow, so that the next round of seawater can enter the inner chamber 5 to dissolve with the carbon dioxide.

[0091] Afterwards, the air passage 8 is opened and the pressurizing sleeve 4 is driven to reset, so that seawater enters the inner cavity 5 and the next pressurizing cycle is carried out.

[0092] After part of the mixture that has been completely dissolved is discharged, it will enter the next inner chamber 5, so the amount of seawater in each inner chamber 5 cannot be guaranteed to be completely consistent. However, due to the continuous injection of carbon dioxide gas, when the inner chamber 5 is pressurized, there must be carbon dioxide that has just passed through it. Therefore, each pressurization chamber 1 must pressurize the carbon dioxide and seawater inside it simultaneously when implementing pressurization, so as to achieve the purpose of dissolving carbon dioxide in seawater.
