Abstract
Description
Technical Field
[0001] This invention relates to the field of high-pressure carbon dioxide pipeline transportation technology, specifically a high-pressure carbon dioxide pipeline transportation device. Background Technology
[0002] In the industrial field, high-pressure carbon dioxide is widely used in many important processes such as oil extraction, chemical synthesis, and food preservation. In oil extraction, it is used to enhance oil recovery by injecting it into oil-bearing formations to increase crude oil recovery. In chemical synthesis, it is often used as a reaction raw material or medium to drive chemical reactions. In food preservation, it can inhibit the growth of microorganisms and extend the shelf life of food.
[0003] As the conveying pressure increases and the conveying distance grows, the carbon dioxide inside the pipeline rubs frequently against the pipe wall. In addition, the heat generated during the compression process accumulates, causing the temperature of the conveying pipeline to rise sharply. Once the temperature exceeds the safety threshold, the physical state of the carbon dioxide may change. Changes in parameters such as density and viscosity will lead to a significant decrease in conveying efficiency, and may even trigger dangerous chemical reactions such as polymerization and decomposition of the carbon dioxide inside the pipeline, seriously threatening the safety of the entire conveying system. To address this, we propose a high-pressure carbon dioxide pipeline conveying device. Summary of the Invention
[0004] The purpose of this invention is to provide a high-pressure carbon dioxide pipeline transportation device.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-pressure carbon dioxide pipeline conveying device, comprising a conveying pipeline and a controller, wherein the outer surface of the conveying pipeline is wrapped with a heat dissipation component, a pressure relief component is installed at one end of the conveying pipeline, and an alarm component is installed inside the controller;
[0006] The heat dissipation assembly includes a shell, a support column, thermally conductive cotton, a bottom shell, a liquid injection tube, and a leak-proof plug. The support column is fixedly connected to the upper surface of the bottom shell. The thermally conductive cotton has evenly distributed holes inside and is disposed on the upper surface of the bottom shell. The shell is fixedly connected to one side of the support column. A liquid injection port is penetrating the surface of the shell. The liquid injection tube is fixedly connected to the liquid injection port. The leak-proof plug is placed at one end of the liquid injection tube.
[0007] As a further aspect of the present invention: an adhesive patch is installed on the inner wall surface of the bottom shell, and the heat dissipation component is fixed to the outer surface of the delivery pipe by the adhesive patch.
[0008] As a further embodiment of the present invention: the left end of the conveying pipe is threadedly connected to one end of the tee, a sealing plate A is provided between the conveying pipe and the tee, and the pressure relief assembly is placed inside the tee.
[0009] As a further embodiment of the present invention: the pressure relief assembly includes a hydraulic rod, a return spring, a pressure-bearing block, and a fixed base;
[0010] The pressure block is fixedly connected to one end of the hydraulic rod, the return spring is sleeved on the outer surface of the hydraulic rod, the fixed base is movably connected to one side of the tee, and one end of the hydraulic rod is in contact with one end of the fixed base.
[0011] As a further embodiment of the present invention: a pressure relief port is provided on the rear side of the pressure block, and a dust plug is installed at one end of the pressure relief port. One end of the dust plug is connected to the outer surface of the tee through an anti-loss rope.
[0012] As a further embodiment of the present invention: the right end of the conveying pipeline is connected to the controller, the alarm component includes an alarm light, an alarm and a pressure detector, the alarm light is fixedly connected to the front side of the controller, the alarm is fixedly connected to both sides of the controller, the pressure detector is placed inside the controller, and the pressure detector is located inside the conveying pipeline.
[0013] As a further embodiment of the present invention: a carbon dioxide booster pump is threadedly connected to the left side of the tee, a sealing plate B is provided between the tee and the carbon dioxide booster pump, and the carbon dioxide booster pump is fixed above the platform by screws.
[0014] As a further aspect of the present invention: the controller is mounted on top of the platform.
[0015] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:
[0016] 1. This invention wraps a heat dissipation component around the outside of the conveying pipeline. During operation, the coolant injected through the injection port quickly absorbs heat and vaporizes. The vapor diffuses into the low-temperature area inside the heat dissipation component and then condenses and flows back. This efficient heat transfer cycle not only quickly removes a large amount of heat but also makes the surface temperature of the pipeline uniformly distributed, effectively avoiding local overheating. This achieves the effect of efficiently reducing the temperature of the conveying pipeline and preventing high-pressure carbon dioxide from causing danger due to abnormal temperature.
[0017] 2. This invention provides a pressure relief assembly consisting of a hydraulic rod, a return spring, a pressure-bearing block, and a fixed base inside the tee. When the pressure inside the pipeline is too high, the pressure-bearing block pushes the hydraulic rod to compress the return spring and open the pressure relief port, thereby automatically releasing the excessive pressure, ensuring the safety of pipeline transportation, and preventing accidents such as pipeline rupture caused by excessive pressure.
[0018] 3. This invention installs a pressure detector inside the controller and alarm lights and alarms on the front and sides of the controller. When the pressure detector detects an abnormal pressure in the pipeline, it immediately triggers the alarm lights and alarms, thereby timely alerting the staff so that they can take quick measures to ensure the safe and stable operation of the entire high-pressure carbon dioxide conveying device.

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.
[0029] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0030] Please see the appendix Figure 1 -Appendix Figure 7 This invention discloses a high-pressure carbon dioxide pipeline transportation device, mainly comprising two key components: a transportation pipeline 1 and a controller 2. A heat dissipation component 3 is tightly wrapped around the outer surface of the transportation pipeline 1. This component plays a crucial role in ensuring the safe and stable transportation of high-pressure carbon dioxide. The heat dissipation component 3 is composed of a shell 31, a support column 32, thermally conductive cotton 33, a bottom shell 34, a liquid injection pipe 35, and a leak-proof plug 36. The support column 32 is firmly fixed to the upper surface of the bottom shell 34, serving as support and separation, providing the basic framework for the subsequent installation and layout of other components. The thermally conductive cotton 33 has evenly distributed holes inside, which are systematically laid on the upper surface of the bottom shell 34. Due to its excellent thermal conductivity, it can quickly conduct heat from the surface of the transportation pipeline 1. When coolant is injected, the heat is quickly absorbed by the coolant and then vaporized. The vapor expands within the heat dissipation component 3. After dissipating to the low-temperature area, the condensed coolant flows back. The outer shell 31 is fixedly connected to one side of the support column 32, acting as a protective cover to enclose the internal heat-conducting cotton 33 and coolant, preventing external factors from interfering with the heat dissipation process. The surface of the outer shell 31 has a liquid injection port, and the liquid injection pipe 35 is tightly fixedly connected to the liquid injection port. Through the liquid injection pipe 35, the operator can easily inject coolant into the heat dissipation component 3. The anti-leak plug 36 is firmly placed at one end of the liquid injection pipe 35. After the liquid injection is completed, it can effectively prevent coolant leakage and ensure the normal operation of the heat dissipation component 3. The inner wall surface of the bottom shell 34 is equipped with an adhesive piece 37. Through the adhesive piece 37, the heat dissipation component 3 can be firmly attached to the outer surface of the delivery pipe 1, ensuring that the heat dissipation component 3 and the delivery pipe 1 are in close contact during the delivery process, achieving efficient heat transfer, thereby effectively reducing the temperature of the delivery pipe 1 and preventing the high-pressure carbon dioxide from causing danger due to abnormal temperature.
[0031] In Example 1, a pressure relief assembly 4 is installed at one end of the conveying pipe 1. The left end of the conveying pipe 1 is threadedly connected to one end of the tee 11. A sealing plate 1101 is provided between the conveying pipe 1 and the tee 11. The pressure relief assembly 4 is placed inside the tee 11. The pressure relief assembly 4 includes a hydraulic rod 41, a return spring 42, a pressure block 43, and a fixed base 44. The pressure block 43 is fixedly connected to one end of the hydraulic rod 41. The return spring 42 is sleeved on the outer surface of the hydraulic rod 41. The fixed base 44 is movably connected to one side of the tee 11. One end of the hydraulic rod 41 is in contact with one end of the fixed base 44. A pressure relief port 45 is provided on the rear side of the pressure block 43. A dust plug 46 is installed at one end of the pressure relief port 45. One end of the dust plug 46 is connected to the outer surface of the tee 11 through an anti-loss rope.
[0032] Specifically, a tee 11 is installed at the left end of the conveying pipeline 1 using a threaded connection. This threaded connection not only facilitates installation and disassembly, but also features an A-sealing plate 1101 at the connection point. The A-sealing plate 1101 greatly enhances the sealing of the connection, preventing high-pressure carbon dioxide leakage and ensuring the safety and efficiency of the conveying process. The pressure relief component 4 is cleverly placed inside the tee 11. The pressure relief component 4 mainly consists of a hydraulic rod 41, a return spring 42, a pressure-bearing block 43, and a fixed base 44. The pressure-bearing block 43 is firmly fixed to one end of the hydraulic rod 41, and the return spring 42 is sleeved on the outer surface of the hydraulic rod 41. When the pressure inside the pipeline is normal, the return spring 42 is in its natural state, providing stable support for the pressure-bearing block 43. When the pressure rises abnormally, the return spring 42 can also play a role in buffering and regulating. The fixed base 44 is movably connected to one side of the tee 11, with one end of the hydraulic rod 41 contacting one end of the fixed base 44. This design allows the pressure relief component 4 to... The various components form an organic whole, capable of working collaboratively. When the pressure inside the pipeline is too high, the pressure block 43 will push the hydraulic rod 41 under pressure, causing the hydraulic rod 41 to compress the return spring 42. As the return spring 42 is compressed, the pressure block 43 gradually moves, thereby opening the pressure relief port 45 on its rear side. One end of the pressure relief port 45 is equipped with a dust plug 46. Under normal circumstances, the dust plug 46 can prevent dust, debris, etc. from entering the pressure relief port 45, avoiding blockage and ensuring that the pressure relief component 4 can work normally when needed. Moreover, one end of the dust plug 46 is connected to the outer surface of the tee 11 through an anti-loss rope. This thoughtful design effectively prevents the dust plug 46 from being lost during use, ensuring the integrity and reliability of the entire device. When the pressure inside the pipe is too high, the high-pressure carbon dioxide will directly push open the dust plug 46 and then be discharged through the pressure relief port 45, thereby quickly reducing the pressure inside the pipeline, ensuring the safety of pipeline transportation, and preventing serious accidents such as pipeline rupture caused by excessive pressure.
[0033] In embodiment 2, the controller 2 is installed above the platform 7. An alarm component 5 is installed inside the controller 2. The right end of the conveying pipe 1 is connected to the controller 2. The alarm component 5 includes an alarm light 51, an alarm 52, and a pressure detector 53. The alarm light 51 is fixedly connected to the front of the controller 2, the alarm 52 is fixedly connected to both sides of the controller 2, and the pressure detector 53 is placed inside the controller 2 and inside the conveying pipe 1.
[0034] Specifically, the controller 2 is tightly connected to the right end of the conveying pipeline 1. This connection ensures that the controller 2 can obtain the pressure information inside the conveying pipeline 1 in real time, providing a solid foundation for accurate judgment and timely response. The alarm component 5 mainly consists of three parts: an alarm light 51, an alarm 52, and a pressure detector 53. The pressure detector 53 is placed inside the controller 2 and precisely located inside the conveying pipeline 1, enabling it to accurately sense the pressure value inside the conveying pipeline 1. During normal conveying, the pressure detector 53 continuously collects pressure data and feeds this data back to the controller 2. When the pressure inside the conveying pipeline 1 is within the normal range, the entire device operates smoothly. However, if an accident occurs, such as carbon dioxide... If the pressure in the delivery pipeline 1 exceeds the safety threshold due to abnormal operation of the booster pump 6, pipeline blockage, or poor heat dissipation of the heat dissipation component 3, the pressure detector 53 will immediately detect this change and quickly transmit the abnormal signal to the controller 2. Upon receiving the abnormal signal, the controller 2 will quickly trigger the alarm light 51 and the alarm 52, enabling the staff to notice the abnormal pressure in the delivery pipeline 1 at the first moment, so that they can quickly take corresponding measures, such as adjusting the operating parameters of the carbon dioxide booster pump 6, checking whether the pipeline is blocked, or checking the operating status of the heat dissipation component 3, thereby ensuring that the entire high-pressure carbon dioxide delivery device can operate safely and stably, and avoiding various dangers and accidents caused by abnormal pressure.
[0035] In embodiment 3, a carbon dioxide booster pump 6 is threadedly connected to the left side of the tee 11. A sealing plate 1102 B is provided between the tee 11 and the carbon dioxide booster pump 6. The carbon dioxide booster pump 6 is fixed above the platform 7 by screws.
[0036] Specifically, the left side of the tee 11 is connected to the booster pump via a thread, and a B sealing plate 1102 is placed at the connection point to effectively prevent high-pressure carbon dioxide leakage, ensure safe transportation, and avoid resource waste and safety hazards. At the same time, the booster pump is fixed to the platform 7 with screws, and the platform 7 provides stable support for it to avoid performance being affected by vibration displacement during operation.
[0037] Working principle:
[0038] First, the carbon dioxide booster pump 6 is turned on, and the pressurized carbon dioxide is injected into the delivery pipe 1 through the threaded connection of the tee 11 with the A sealing plate 1101. During the delivery process, the heat generated by the friction between the high-pressure carbon dioxide and the pipe wall and the compression is absorbed by the heat dissipation component 3 wrapped around the outside of the delivery pipe 1. The operator injects coolant into the heat dissipation component 3 through the injection pipe 35 and the injection port. After absorbing the heat, the coolant quickly vaporizes. The vapor diffuses into the low-temperature area within the outer shell 31 and condenses and flows back, continuously circulating and efficiently removing heat, so that the surface temperature of the pipe is evenly distributed, preventing safety accidents caused by abnormal temperature. At the same time, the pressure detector 53 monitors the pressure in the delivery pipe 1 in real time. The data is transmitted to the controller 2. When the pressure is normal, the pressure relief component 4 is in the initial state. The pressure block 43, supported by the return spring 42, seals the pressure relief port 45. The dust plug 46 also prevents debris from entering. Once the pressure detector 53 detects that the pressure exceeds the safety threshold, the controller 2 immediately triggers the alarm light 51 and the alarm 52 to remind the staff. If the pressure continues to rise, the excessive pressure in the pipeline will push the pressure block 43, causing it to drive the hydraulic rod 41 to compress the return spring 42, opening the pressure relief port 45. High-pressure carbon dioxide will be discharged, reducing the pressure in the pipeline. After the pressure returns to normal, the return spring 42 pushes the pressure block 43 to reset and reseal the pressure relief port 45. At this point, the entire process ends.
