Description

Technical Field

[0001] This invention relates to the field of carbon dioxide sequestration leakage simulation technology, specifically to a carbon dioxide geological sequestration leakage artificial control simulation device. Background Technology

[0002] Authorized publication number CN219737404U discloses an artificial control simulation device for carbon dioxide geological storage leakage. This device features a carbon dioxide chamber at the bottom of a simulation chamber, inside which is a carbon dioxide detector. A large amount of soil is placed on a partition within the simulation chamber. Pressure is applied to the soil using a pressing component to simulate soil layers of different densities. The carbon dioxide detector monitors the carbon dioxide emitted into and above the soil, improving the device's functionality. Furthermore, a carbon dioxide adsorption box is installed on the right side of the simulation chamber, containing activated carbon to adsorb the carbon dioxide within the chamber, preventing it from entering the working chamber, thus enhancing environmental protection and improving the safety of the simulation device.

[0003] However, the applicant found that as carbon dioxide leakage increased, the activated carbon gradually became saturated and needed to be replaced. However, existing technology cannot replace activated carbon without leaking carbon dioxide. Therefore, we propose a simulated device for artificial control of carbon dioxide geological sequestration leakage. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] As mentioned in the background section, existing technologies address the problem that activated carbon gradually becomes saturated with increasing carbon dioxide leakage, necessitating replacement. However, existing technologies cannot replace activated carbon without causing further carbon dioxide leakage. This invention proposes a simulated device for artificially controlling carbon dioxide geological sequestration leakage.

[0017] Example 1 Reference Figures 1 to 4 A simulated device for artificial control of carbon dioxide geological storage leakage includes a simulation box 1, a breathable baffle 2 inside the simulation box 1 for carbon dioxide to pass through in case of leakage, a pressure sensor 3 and a soil layer 4 on the breathable baffle 2, a carbon dioxide detector 5 on the bottom inner wall of the simulation box 1, a carbon dioxide delivery pipe 6 connected to the simulation box 1 below the breathable baffle 2, a pressing component 7 on the simulation box 1 above the soil layer 4, a control panel 8 on the simulation box 1, a connecting pipe 9 on the upper right side of the simulation box 1, and a sealing ring 10 on the inner wall of the connecting pipe 9. The inner wall of the sealing ring 10 is fitted with a fixing tube 11, which is connected to the adsorption box 12. The bottom of the adsorption box 12 is provided with a slide rod 13, which is slidably connected to the slide rail 14. The slide rail 14 is set on the simulation box 1, and the slide rail 14 is provided with screws that are connected to the slide rod 13. An activated carbon adsorption assembly is installed inside the adsorption box 12.

[0018] The activated carbon adsorption assembly includes a base plate 15, the bottom of which is attached to the bottom inner wall of the adsorption box 12, a fixing frame 16 is attached to the top of the base plate 15, activated carbon 17 located in the fixing frame 16 is attached to the top of the base plate 15, and the right side of the activated carbon 17 is attached to the right inner wall of the adsorption box 12.

[0019] Connect the simulation chamber 1 to the power supply, and connect the carbon dioxide delivery pipe 6 to the carbon dioxide delivery device. The carbon dioxide is delivered into the simulation chamber 1 through the carbon dioxide delivery device. The carbon dioxide detector 5 can monitor the carbon dioxide concentration below the breathable partition 2 and display it on the control panel 8. At the same time, press the pressing component 7 down. The pressure sensor 3 can monitor the pressure of the pressing component 7. The density of the soil layer 4 can be obtained by the pressure. The leakage data of carbon dioxide at different densities can be obtained by the carbon dioxide emission. The carbon dioxide released from the soil layer 4 enters the adsorption box 12 through the fixed pipe 11 and is then adsorbed by the activated carbon 17 to prevent carbon dioxide from being released from the simulation chamber 1 and damaging the surrounding environment.

[0020] A crossbar 30 is provided on the left inner wall of the fixed frame 16. A spring 32 is provided on the right inner side of the crossbar 30. A movable rod 31 is attached to the right side of the spring 32 and is attached to the inner wall of the crossbar 30. The right side of the movable rod 31 is attached to the inner wall of the adsorption box 12. Activated carbon 17 is attached to the crossbar 30 and the movable rod 31. Through the right inner wall of the adsorption box 12, the movable rod 31 compresses the spring 32, so that the right side of the movable rod 31 is aligned with the activated carbon 17.

[0021] A motor 27 is installed on the right side of the adsorption box 12. The output shaft of the motor 27 is equipped with a drive pulley 28, which is connected to a driven pulley 29. The driven pulley 29 is mounted on a rotating shaft 25, which is connected to a bearing bracket 26. The bearing bracket 26 is mounted on the adsorption box 12. Screws 24 are installed on both the top and bottom sides of the rotating shaft 25. The threads on the two screws 24 are turned in opposite directions. Mounting rods 23 are screwed onto both screws 24, causing the mounting rods 23 to move in opposite directions. Vertical rods 21 are installed on the left end of both mounting rods 23. The vertical rods 21 pass through the top and bottom sides of the adsorption box 12. The bottom vertical rod 21 is connected to the bottom plate 15. The bottom of the top vertical rod 21 is connected to a movable plate 22 located above the fixed tube 11. The movable plate 22 and the bottom plate 15 move the same distance. When the movable plate 22 comes into contact with the activated carbon 17, the movable plate 22 blocks the fixed tube 11.

[0022] A baffle 18 runs through the right side of the adsorption box 12. A limiting rod 19 runs vertically through the baffle 18. The bottom end of the limiting rod 19 is inserted into the bottom block 20 connected to the adsorption box 12. By moving the limiting rod 19 upward, the limiting of the baffle 18 can be removed, and then the baffle 18 can be taken out so that the activated carbon 17 can be taken out from the position of the baffle 18 for replacement.

[0023] A balloon 36 is connected to the simulation chamber 1 to squeeze the unadsorbed carbon dioxide in the adsorption chamber 12 back into the simulation chamber 1, and then temporarily store it through the balloon 36.

[0024] Example 2 Reference Figure 1 A support rod 33 is provided on the bottom right side of the simulation box 1. An electric telescopic rod 34 is provided on the top of the support rod 33. A support block 35 is provided at the output end of the electric telescopic rod 34. The top of the support block 35 is attached to the bearing frame 26. The support block 35 is moved by the electric telescopic rod 34, which can support the bearing frame 26 and improve the stability of the adsorption box 12.

[0025] The rest of the structure is the same as in Example 1.

[0026] When it is necessary to replace activated carbon 17, move the movable plate 22 and the base plate 15 to the opposite side until the movable plate 22 just blocks the fixed tube 11. At this time, the movable plate 22 and the activated carbon 17 are in contact, and the carbon dioxide can be squeezed into the simulation box 1. As the base plate 15 moves upward, the movable rod 31 remains in contact with the adsorption box 12. After removing the baffle 18, the movable rod 31 is no longer under the pressure of the baffle 18, causing the spring 32 to push the movable rod 31 to move to the right, making it convenient for the user to pull the movable rod 31. By pulling the movable rod 31, the crossbar 30 pulls the fixed frame 16 to the right on the base plate 15, allowing the fixed frame 16 to be removed. This facilitates the removal and replacement of the activated carbon 17 pulled out of the adsorption box 12. After replacement, the activated carbon 17 is put back into the fixed frame 16, and then the baffle 18 is reinstalled. The base plate 15 and the movable plate 22 are then moved to opposite sides. In this invention, the motor 27 drives the bidirectional screws 24 to rotate, causing the base plate 15 and the movable plate 22 to move synchronously towards each other by the same distance. During the movement, the movable plate 22 squeezes the residual carbon dioxide in the adsorption box 12 back into the simulation box 1 and temporarily stores it through the balloon 36. When the movable plate 22 comes into contact with the activated carbon 17, it seals the fixed tube 11, creating a carbon dioxide-free enclosed space inside the adsorption box 12. Then, the baffle 18 is removed, and the movable rod 31, no longer obstructed by the inner wall of the adsorption box 12, extends to the right under the action of the spring 32. The operator can then directly pull the movable rod 31 to slide the fixed frame 16 and activated carbon 17 out. The entire process involves zero carbon dioxide leakage and is seamless and quick, achieving mechanical linkage between compression exhaust, physical sealing, and pull-out replacement through a single power source.
