Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide storage technology, and more specifically, relates to a carbon dioxide condensation device. Background Technology

[0002] To achieve efficient storage and transportation of liquid carbon dioxide, the industry widely adopts cryogenic liquefaction technology, which cools it to a specific low temperature, keeping it in a liquid state at the corresponding saturated vapor pressure. This significantly reduces its volume compared to its gaseous state, thereby significantly improving storage and transportation efficiency and reducing operating costs.

[0003] During long-term storage, ambient heat continuously seeps into the system through the tank's insulation layer and exposed metal pipes, causing the liquid carbon dioxide inside the tank to absorb heat and vaporize, resulting in a continuous increase in pressure in the gas phase space. When the pressure exceeds the container's maximum operating pressure, the safety valve will be forced to open to ensure safety, releasing high concentrations of carbon dioxide directly into the atmosphere. This release process not only wastes valuable carbon dioxide resources but also exacerbates the greenhouse effect, leading to significant negative environmental and economic consequences. Utility Model Content

[0004] To address the problem that a certain amount of carbon dioxide needs to be released to the outside when the internal pressure of a carbon dioxide storage tank is too high, this utility model proposes a carbon dioxide condensation device to overcome the aforementioned technical problems existing in the relevant technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a carbon dioxide condensation device, comprising a support plate. The support plate is characterized by having extension components on both sides, an installation component at the bottom of the extension components, a cooling component at the top of the support plate, and a reflux connection component at the front of the cooling component. The reflux connection component connects a storage tank to the cooling component, allowing high-temperature carbon dioxide inside the storage tank to flow into the cooling component, while the hydraulically cooled carbon dioxide flows back into the storage tank through the reflux connection component.

[0006] Furthermore, the expansion assembly includes an expansion plate, which is provided on both sides of the support plate. A fixing frame is fixedly connected to the opposite side of the expansion plate and the support plate. A movable seat is movably connected to the outer surface of the fixing frame, and a rotating rod is rotatably connected inside the movable seat.

[0007] Furthermore, one end of each of the two rotating rods is rotatably connected to the corresponding extension plate and support plate, respectively. A connecting plate is provided at the bottom of the support plate, and the connecting plate is rotatably connected to the movable seats on both sides of the support plate.

[0008] Furthermore, the mounting assembly includes a base plate, two of which are symmetrically arranged at the bottom of the support plate. Two fixing frames are fixedly installed on the top of the base plate. A lifting screw is rotatably connected inside the fixing frame. The lifting frame is threadedly connected to the outer surface of the lifting screw. The top of the lifting frame is fixedly installed at the bottom of the extension plate. The lifting frame is movably connected to the fixing frame.

[0009] Furthermore, a storage box is fixedly installed at the bottom of the base plate corresponding to the lifting screw, and a linkage rod is provided on the bottom plate of the base plate, the linkage rod passing through the storage box. Furthermore, the bottom end of the lifting screw extends into the interior of the storage box, and bevel gears are fixedly connected to both the linkage rod and the outer surface of the lifting screw, with the two bevel gears meshing together.

[0010] Furthermore, a drive motor is fixedly installed on the top of the base plate, and gears are fixedly connected to the output end of the drive motor and the outer surface of the linkage rod. The two gears mesh together, and a shielding shell is provided on the outer surface of the two gears. The shielding shell is fixedly connected to the base plate, and a caster wheel is fixedly connected to the bottom of the base plate.

[0011] Furthermore, the cooling assembly includes a refrigerator, which is fixedly installed on the top of a support plate. A support sleeve is fixedly installed on the top of the support plate. A condenser tank is disposed inside the support sleeve. A cooling pipe is fixedly installed on the outer surface of the refrigerator, and the cooling pipe passes through the condenser tank. The cooling pipe inside the condenser tank is spirally arranged.

[0012] Furthermore, the connection reflux assembly includes a connecting pipe and a reflux pipe, both of which are fixedly connected to the bottom of the condenser.

[0013] Furthermore, a solenoid valve is fixedly installed at the bottom end of both the connecting pipe and the return pipe. A pressure sensor is installed inside the solenoid valve. A hose is fixedly connected to the bottom end of the solenoid valve, and a connecting flange is fixedly connected to the bottom end of the hose.

[0014] This utility model has the following beneficial effects: 1. This utility model connects the storage tank and the cooling component together by means of a reflux assembly. When the gas pressure inside the storage tank is high, carbon dioxide can flow into the cooling component through the reflux assembly. The carbon dioxide that has been cooled and formed into liquid in the cooling component then flows back into the storage tank through the reflux assembly until the gas pressure inside the storage tank returns to normal. The above arrangement eliminates the need to directly discharge carbon dioxide to the outside of the storage tank when the gas pressure inside the tank is too high, thereby effectively avoiding the waste of resources and preventing the emitted carbon dioxide from affecting the external environment.

[0015] 2. This utility model involves pulling two extension plates, which in turn move two base plates via corresponding fixed and lifting frames, allowing the distance between the two base plates to be adjusted according to the width of the storage tank. Furthermore, by driving a drive motor, the lifting frame moves within the fixed frame via two meshing gears, a linkage rod, meshing bevel gears, and a lifting screw, allowing the support plate to be adjusted according to the height of the storage tank. These features enable the support plate to adapt to storage tanks of different sizes, resulting in high overall applicability of the device.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Example 1: Please refer to Figures 1-4 As shown, this utility model is a carbon dioxide condensation device, including a support plate 1, expansion components 2 are provided on both sides of the support plate 1, an installation component 3 is provided at the bottom of the expansion components 2, a cooling component 4 is provided at the top of the support plate 1, and a connecting return component 5 is provided at the front side of the cooling component 4. The connecting reflux assembly 5 is used to connect the storage tank and the cooling assembly 4 together, so that the high-temperature carbon dioxide inside the storage tank flows into the interior of the cooling assembly 4, and the hydraulic carbon dioxide formed after cooling flows back into the interior of the storage tank through the connecting reflux assembly 5.

[0022] In practical use, the mounting component 3 at the bottom of component 2, preferably a welding fulcrum or welding support in this embodiment, can be used to adjust the distance between the welding supports of the mounting component 3 by expanding the expansion component 2, so as to adapt to different sizes and external curvatures of different storage tanks, and to weld the welding supports of the mounting component 3 to the storage tank. After the support plate 1 is fixed in a suitable position on the storage tank by the expansion component 2, the connecting return component 5 is connected to the storage tank. When the carbon dioxide inside the storage tank increases due to the rise in temperature, the connecting return component 5 is opened. At this time, the high-temperature carbon dioxide can flow through the connecting return component 5 to the interior of the cooling component 4. After the cooling component 4 exchanges heat with the high-temperature carbon dioxide, it can condense into a liquid state, and the liquid carbon dioxide flows back into the interior of the storage tank through the connecting return component 5. When the pressure inside the storage tank drops to a predetermined value, the connecting return component 5 is closed.

[0023] Specifically, the storage tank and cooling assembly 4 can be connected together by the reflux assembly 5. When the internal pressure of the storage tank rises to a preset value, the cooling assembly 4 is turned on. Gaseous carbon dioxide can flow into the interior of the cooling assembly 4 through the reflux assembly 5. Inside the cooling assembly 4, the gaseous carbon dioxide comes into contact with the heat exchange tubes, and the cooling assembly 4 cools the heat exchange tubes to -30°C to -40°C. The cooled and liquid carbon dioxide then flows back into the storage tank through the reflux assembly 5 until the internal pressure of the storage tank returns to the normal preset value, at which point the cooling assembly 4 is turned off. This configuration ensures that when the internal pressure of the storage tank is too high, carbon dioxide does not need to be directly discharged to the outside of the storage tank, thus effectively avoiding resource waste and preventing the emitted carbon dioxide from affecting the external environment.

[0024] Example 2: Please refer to Figures 1-7 As shown, unlike Embodiment 1, the expansion component 2 includes an expansion plate 201. The expansion plate 201 is provided on both sides of the support plate 1. A fixing frame 202 is fixedly connected to the opposite side of the expansion plate 201 and the support plate 1. A movable seat 203 is movably connected to the outer surface of the fixing frame 202. A rotating rod 204 is rotatably connected inside the movable seat 203. One end of the two rotating rods 204 is rotatably connected to the corresponding expansion plate 201 and support plate 1, respectively. A connecting plate 205 is provided at the bottom of the support plate 1. The connecting plate 205 is rotatably connected to the movable seats 203 on both sides of the support plate 1.

[0025] By pulling the extension plate 201, the extension plate 201 can pull the rotating rod 204, causing the rotating rod 204 to rotate and drive the movable seat 203 to slide on the fixed frame 202. At this time, the distance between the extension plate 201 and the support plate 1 can increase, and the distance between the two sets of mounting components 3 at the bottom of the two extension plates 201 also changes. This setting allows the distance between the two mounting components 3 to be adjusted according to the width of the storage tank. During the above movement, the movable seats 203 on both sides of the support plate 1 can move synchronously under the connection of the connecting plate 205. This setting allows the two extension plates 201 to move synchronously when the extension plates 201 on both sides of the support plate 1 are moved. Furthermore, two rotating rods 204 are staggered vertically between the support plate 1 and the extension plate 201. Under the constraint of the two rotating rods 204, the overall stability of the extension plate 201 during movement is ensured, and the connection between the extension plate 201 and the support plate 1 is also relatively firm.

[0026] Example 3: Please refer to Figures 1-7 As shown, unlike Embodiment 1, in actual use, the mounting component 3 can be replaced with the following structure: The mounting component 3 includes a base plate 301, two base plates 301 are symmetrically arranged at the bottom of the support plate 1, two fixing frames 302 are fixedly installed on the top of the base plate 301, a lifting screw 303 is rotatably connected inside the fixing frame 302, a lifting frame 304 is threadedly connected to the outer surface of the lifting screw 303, the top of the lifting frame 304 is fixedly installed at the bottom of the extension plate 201, and the lifting frame 304 is movably connected to the fixing frame 302.

[0027] By rotating the lifting screw 303, the lifting screw 303 can drive the lifting frame 304 to move inside the fixed frame 302, thereby changing the length of the fixed frame 302 and the lifting frame 304. At the same time, under the lifting of the lifting frame 304, the extension plate 201 can drive the support plate 1 to rise and fall through the rotating rod 204, so that the height of the support plate 1 can be adjusted according to the height of the storage tank.

[0028] A storage box 305 is fixedly installed on the bottom of the base plate 301 corresponding to the lifting screw 303. A linkage rod 306 is provided on the bottom plate of the base plate 301. The linkage rod 306 passes through the storage box 305. The bottom end of the lifting screw 303 extends into the interior of the storage box 305. A bevel gear 307 is fixedly connected to the outer surface of both the linkage rod 306 and the lifting screw 303. The two bevel gears 307 mesh together.

[0029] The two fixed frames 302 and the lifting frame 304 on the top of the base plate 301 ensure the overall stability of the extension plate 201. At the same time, when the linkage rod 306 is rotated, the linkage rod 306 can drive the two lifting screws 303 synchronously through two sets of meshing bevel gears 307. This allows the two lifting screws 303 to drive the corresponding lifting frames 304 simultaneously. This arrangement ensures that when the height of the extension plate 201 is adjusted, the extension plate 201 will not jam due to the asynchronous rotation of the two lifting screws 303.

[0030] A drive motor 308 is fixedly installed on the top of the base plate 301. Gears 309 are fixedly connected to the output end of the drive motor 308 and the outer surface of the linkage rod 306. The two gears 309 mesh together. A shielding shell 310 is provided on the outer surface of the two gears 309. The shielding shell 310 is fixedly connected to the base plate 301. A caster wheel 311 is fixedly connected to the bottom of the base plate 301.

[0031] By driving the drive motor 308, the drive motor 308 drives the linkage rod 306 to rotate through two meshing gears 309. The casters 311 allow the base plate 301 to move, making it convenient to transport the entire device.

[0032] The cooling assembly 4 includes a refrigerator 401, which is fixedly installed on the top of the support plate 1. A support sleeve 402 is fixedly installed on the top of the support plate 1. A condenser 403 is provided inside the support sleeve 402. A cooling pipe 404 is fixedly installed on the outer surface of the refrigerator 401. The cooling pipe 404 penetrates the condenser 403 and is spirally arranged inside the condenser 403.

[0033] Guided by the cooling pipe 404, the coolant can flow from the refrigerator 401 to the interior of the condenser 403, and then flow out of the condenser 403 before flowing back into the refrigerator 401 under the guidance of the cooling pipe 404. Because the cooling pipe 404 inside the condenser 403 is spirally arranged, the high-temperature carbon dioxide inside the condenser 403 can better exchange heat with the coolant inside the cooling pipe 404.

[0034] The connection reflux assembly 5 includes a connecting pipe 501 and a reflux pipe 502. Both the connecting pipe 501 and the reflux pipe 502 are fixedly connected to the bottom of the condenser tank 403. A solenoid valve 503 is fixedly installed at the bottom end of both the connecting pipe 501 and the reflux pipe 502. A pressure sensor is installed inside the solenoid valve 503. A hose 504 is fixedly connected to the bottom end of the solenoid valve 503. A connecting flange 505 is fixedly connected to the bottom end of the hose 504.

[0035] The hoses 504 on both the connecting pipe 501 and the return pipe 502 are connected to the tank interface via the connecting flange 505. When the internal pressure of the tank rises, the pressure sensor transmits the detected pressure change to the controller, which then controls the solenoid valve 503 to open. At this time, since both the connecting pipe 501 and the return pipe 502 are equipped with check valves, the carbon dioxide inside the tank can only flow through the connecting pipe 501 to the condenser 403. When the high-temperature carbon dioxide is cooled and forms a liquid, the tilted design of the condenser 403 allows the liquid carbon dioxide to flow into the return pipe 502 under gravity and then back into the tank via the hose 504 at the bottom of the return pipe 502. When the internal pressure of the tank returns to normal, the controller receives a signal from the pressure sensor and then controls the two solenoid valves 503 to close.

[0036] By pulling the two extension plates 201, the two extension plates 201 move the two base plates 301 through the corresponding fixed frame 302 and lifting frame 304, so that the distance between the two base plates 301 can be adjusted according to the width of the storage tank. By driving the drive motor 308, the drive motor 308 drives the lifting frame 304 to move inside the fixed frame 302 through two meshing gears 309, a linkage rod 306, a meshing bevel gear 307, and a lifting screw 303, so that the support plate 1 can be adjusted according to the height of the storage tank. The above configuration allows the support plate 1 to adapt to storage tanks of different specifications, thus making the overall applicability of the device high.
