Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide storage, in particular to an intelligent storage device for carbon dioxide. Background Art

[0002] In the existing field of carbon dioxide storage tank technology, accurately measuring the remaining amount of carbon dioxide in the tank has always been a major challenge facing researchers and engineers. Conventional methods all use U-tube liquid level measurement methods, such as the Chinese utility model patent publication number CN204269184U, which discloses a detachable liquid level detection mechanism for low-pressure carbon dioxide fire extinguishing devices. Although the principle of U-tube liquid level measurement is simple and intuitive, problems often arise in actual application scenarios. Specifically, due to its physical properties, carbon dioxide easily condenses into dry ice particles during storage and use. These tiny dry ice particles gradually clog the narrow tube portion of the U-tube, causing distorted or even complete failure of liquid level readings. This inaccuracy not only weakens the real-time and accuracy of tank management, but also can trigger a series of chain reactions due to misjudgments, such as forced adjustments to production plans, confusion in resource allocation, and even temporary interruptions to production lines, resulting in immeasurable losses to production efficiency and economic benefits.

[0003] In addition, existing traditional carbon dioxide storage tanks do not have corresponding boosting devices. When the amount of carbon dioxide pumped out reaches a certain level, the pressure inside the tank will drop significantly, making it impossible to continue operations. There is no corresponding effective way to utilize the remaining carbon dioxide in the tank, resulting in great waste.

[0004] Furthermore, a high gas-to-liquid ratio of CO2 within a tank significantly impacts the efficiency of pumping out the liquid CO2. Failure to reduce the gas-to-liquid ratio significantly reduces the pumping efficiency. Traditional regulation methods are cumbersome, inefficient, and difficult to achieve precise control, making them unable to meet the high automation and intelligent demands of modern industry.

[0005] Therefore, it is necessary to study an intelligent storage device for carbon dioxide to solve the above problems or alleviate the impact of the above problems. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2As shown, the intelligent storage device for carbon dioxide of the present invention may include:

[0033] A storage tank 1 for containing carbon dioxide;

[0034] A gravity sensing unit, which is disposed at the bottom of the storage tank 1 and is used to measure the weight of the carbon dioxide in the storage tank 1;

[0035] The boosting unit is connected to the storage tank 1 and is used to gasify part of the carbon dioxide in the storage tank 1 .

[0036] Specifically, the storage tank 1 serves as a safe container for containing carbon dioxide and can ensure the storage environment of carbon dioxide; the gravity sensing unit serves as a measuring device for carbon dioxide, and by monitoring the weight of the entire storage tank 1, based on the fact that the weight of the storage tank 1 itself remains unchanged, it can monitor the weight of the carbon dioxide in the storage tank 1, thereby replacing the traditional U-tube liquid level measurement method, and avoiding blockage caused by the formation of dry ice by carbon dioxide and resulting in inaccurate measurement; the boosting unit serves as a boosting device for increasing the internal pressure of the storage tank 1, and by gasifying part of the carbon dioxide in the storage tank 1, ensures the pressure environment in the storage tank 1 and improves the output efficiency of carbon dioxide.

[0037] In this way, the intelligent storage device cooperates with the boosting unit and the gravity sensing unit to facilitate full utilization of the carbon dioxide in the storage tank 1, which can not only ensure the real-time and accuracy of the carbon dioxide content measurement, but also improve the utilization rate of the carbon dioxide in the storage tank 1 and improve production efficiency.

[0038] It should be noted that the storage tank 1 should be made of high-strength, corrosion-resistant materials, such as stainless steel or alloy steel. The storage tank 1 should be installed on a flat, stable foundation to ensure that it will not be displaced or tilted due to vibration or external forces during operation.

[0039] In one example, Figures 1 to 3 As shown, the boosting unit may include a heat exchanger 2 arranged outside the storage tank 1, the heat exchanger 2 is provided with a heat exchange pipe 3 running through it, and both ends of the heat exchange pipe 3 are respectively connected to the interior of the storage tank 1.

[0040] Specifically, both ends of heat exchange tube 3 are connected to the interior of tank 1. Some of the liquid carbon dioxide in tank 1 flows through heat exchange tube 3 and is heated and vaporized by heat exchanger 2. The vaporized carbon dioxide then returns to tank 1, raising the internal pressure of tank 1. Heat exchange tube 3 is carefully designed based on the on-site usage environment to ensure that the gaseous carbon dioxide can flow smoothly back into tank 1, maintaining a stable pressure within tank 1.

[0041] Furthermore, the heat exchanger 2 has a heat exchange cavity, in which a hot fluid for heating the heat exchange tube 3 is contained. The heat exchange tube 3 is bent in a circuitous manner in the heat exchange cavity and has a serpentine disc structure.

[0042] Specifically, heat exchanger 2 includes heat exchange tubes 3 extending through the heat exchange cavity. Heat is transferred between the hot fluid within the cavity and the heat exchange tubes 3, heating the carbon dioxide within the heat exchange tubes 3. Heat exchange tubes 3 are serpentine, coiled structures formed by twisting and turning to increase the length of the heat exchange tubes 3 within the cavity and extend the heating time of the liquid carbon dioxide. Heat exchanger 2 also includes inlets and outlets for the entry and exit of hot fluid, which can be high-temperature gas, high-temperature water, or thermal oil.

[0043] In one example, Figure 1 and Figure 4 As shown, the boosting unit further includes a heater 4 disposed inside the storage tank 1, and the heater 4 is installed on the side wall or bottom wall of the storage tank 1. Specifically, the heater 4 can heat the carbon dioxide in the storage tank 1 by electric heating. Figure 1 The arrows in show that the heater 4 can be arranged at different positions on the side wall or bottom wall of the storage tank 1 .

[0044] Thus, when the intelligent storage device detects that the pressure in storage tank 1 is lower than a preset pressure threshold, it can automatically control the activation of the external heat exchanger 2 for heating, heating the portion of liquid carbon dioxide flowing through the heat exchange tube 3, causing it to quickly convert to gaseous form, thereby increasing the pressure in storage tank 1. When the temperature of the external heat exchanger 2 does not meet the requirements or rapid pressurization is required during use, the internal heater 4 can be activated to directly heat the carbon dioxide in storage tank 1 to accelerate its gasification. In this way, the internal heater 4 and the external heat exchanger 2 work together to achieve the purpose of pressurizing storage tank 1, thereby optimizing the pressure control mechanism in storage tank 1 and solving the problem of traditional storage tanks requiring a discharge pump. The intelligent storage device uses a pressurization unit to ensure that the internal pressure does not rely on a discharge pump and can also output carbon dioxide stably.

[0045] In one example, Figure 1 and Figure 2 As shown, the connection end of the heat exchange tube 3 to the storage tank 1 is equipped with an electric valve 5, which is used to remotely control the on / off state of the heat exchange tube 3. The electric valve 5 opens and closes accordingly with the start and stop of the heat exchanger 2, and can cooperate with the signal connection module and the remote terminal to control the on / off state of the heat exchange tube 3. In combination with the Internet of Things technology, users can accurately open and close the heat exchange tube 3 and the storage tank 1 at any time and any place.

[0046] It should be noted that an outlet pipe 11 for outputting carbon dioxide may be further provided at the bottom of the storage tank 1 , and a corresponding electric valve 5 may also be installed on the outlet pipe 11 .

[0047] In one example, Figure 1and Figure 2 As shown, the gravity sensing unit includes a plurality of gravity sensors 6 evenly distributed at the bottom of the storage tank 1 , and the plurality of gravity sensors 6 cooperate to form a weighing platform for supporting the storage tank 1 .

[0048] Specifically, there can be four gravity sensors 6, located at the four corners of the bottom of the tank 1, to form a stable and reliable weighing platform. These gravity sensors 6 are very sensitive to changes in gravity and can detect subtle fluctuations in the overall weight of the tank 1. Based on the fact that the weight of the tank 1 itself remains unchanged, changes in the carbon dioxide content in the tank 1 can be monitored.

[0049] It should be noted that after monitoring the overall weight change of the storage tank 1, the gravity sensor 6 needs to integrate the preset carbon dioxide density parameters and the real-time temperature correction coefficient, and then use advanced data processing algorithms to perform complex and precise calculations, and finally accurately obtain the total remaining amount of liquid and gaseous carbon dioxide in the storage tank 1, which can provide solid data support for the management of the storage tank 1.

[0050] The gravity sensor 6 can be fixed to the bottom of the storage tank 1 by bolts or welding. The gravity sensor 6 can be a piezoresistive gravity sensor, a capacitive gravity sensor, a vibration gravity sensor or a piezoelectric gravity sensor.

[0051] Further, if Figure 5 As shown, the gravity sensor 6 is a piezoresistive gravity sensor, which works based on the principle of resistance change and consists of a piezoresistor and an elastic body. When the elastic body is deformed by gravity, the resistance value of the piezoresistor changes, thereby achieving the measurement of gravity acceleration.

[0052] In one example, Figure 1 and Figure 4 As shown, the intelligent storage device further includes a pressure sensor 7 and a temperature sensor 8 arranged on the top of the storage tank 1 . The pressure sensor 7 is used to monitor the pressure data inside the storage tank 1 , and the temperature sensor 8 is used to monitor the temperature data inside the storage tank 1 .

[0053] Specifically, temperature sensor 8 is used to accurately monitor the temperature data within storage tank 1, thereby providing temperature information for the management of storage tank 1. Pressure sensor 7, with its excellent measurement accuracy and response speed, can continuously monitor the dynamic changes in the internal pressure of storage tank 1 in real time, thereby assisting the control unit in accurately controlling and maintaining the stability of the internal pressure of storage tank 1.

[0054] It should be noted that the data collected by the pressure sensor 7 is transmitted to the information processing module and accurately compared with the preset pressure threshold. Once it is detected that the pressure in the storage tank 1 is lower than the set lower limit, the intelligent storage device will automatically trigger the self-pressurization program, start the built-in heater 4 and the external heat exchanger 2 to work together to increase the pressure; conversely, if the pressure reaches or exceeds the set upper limit, the intelligent storage device will respond quickly, automatically cut off the power supply of the heater 4 and adjust the working state of the heat exchanger 2 to accurately control and maintain the pressure in the tank within a constant range, thereby ensuring the safety and stability of the operation of the storage tank 1.

[0055] In one example, Figure 1 、 Figure 2 and Figure 4 As shown, the intelligent storage device further includes a safety valve 9 provided on the top of the storage tank 1 , and the safety valve 9 is used for safely releasing pressure when the storage tank 1 is over-pressurized.

[0056] Specifically, several safety valves 9 can be installed, and their number can be set according to the specific operating conditions and safety requirements of the storage tank 1. These safety valves 9, as an important component of pressure management, work in conjunction with the pressure sensor 7. Under the continuous monitoring of the pressure sensor 7, once the pressure in the storage tank 1 abnormally rises to a dangerous threshold, the safety valve 9 will respond quickly, automatically opening and releasing excess pressure, effectively preventing the occurrence of overpressure accidents, ensuring that the storage tank 1 can still maintain safe operation in an emergency, and safeguarding the overall stability and safety of the storage tank 1.

[0057] In one example, Figure 1 、 Figure 2 and Figure 4 As shown, the intelligent storage device further includes a display screen 10 mounted on the outside of the storage tank 1 , and the display screen 10 is used to display parameter information of the storage tank 1 .

[0058] Specifically, the display screen 10 is mounted on the outside of the storage tank 1. As a central information processing and display unit, the display screen 10 can integrate and analyze the detection signals from various sensors on the storage tank 1 (such as gravity sensor 6, pressure sensor 7 and temperature sensor 8, etc.), and convert these signals into accurate liquid level, pressure and temperature data through algorithm processing, and display them on the screen in real time. This design not only improves the immediacy of data acquisition, but also allows operators to accurately control the storage tank 1 through a remote terminal regardless of their location. In addition, the built-in data recording and analysis function of the display screen 10 supports in-depth query of historical data and customized report generation, providing data support for scientific researchers and managers, facilitating in-depth data analysis and scientific decision-making.

[0059] It should be noted that the intelligent storage device may also include a remote terminal (not shown in the drawings) connected to the display screen 10, so that related tasks of the display screen can also be completed through the remote terminal.

[0060] In one example, the display screen 10 has a built-in signal connection module and an information processing module (not shown in the drawings). The signal connection module is used to transmit information between the information processing module and the monitoring equipment and the remote terminal. The information processing module is used to analyze and process the monitoring data of the storage tank 1.

[0061] Specifically, the signal connection module is a bridge for information transmission between the information processing module and various sensors, electric valves 5, remote terminals and other equipment. The information processing module is the analysis and processing center for various monitoring data, and displays the analysis results to the operator for viewing or for the control unit to implement the control program.

[0062] Furthermore, the display screen 10 is also equipped with a control unit and an alarm unit (not shown in the accompanying drawings). The control unit includes an automatic control unit and a manual control unit. The automatic control unit can automatically run the corresponding control program according to the analysis results of the information processing module. The manual control unit can be issued by the operator under operation instructions or controlled by a remote terminal, that is, it can be controlled locally or remotely. The alarm unit may include a low liquid level alarm, a high pressure alarm, and an over-temperature alarm for the storage tank, etc., and has multiple early warning functions. In this way, once the intelligent storage device detects any abnormal situation, such as too low liquid level, excessive pressure, or abnormally high temperature, it will immediately trigger an alarm signal, and can issue an emergency prompt on site through a high-decibel alarm sound, and quickly push the alarm information to the preset remote terminal through remote communication means such as text messages and emails to ensure that abnormal situations can be responded to and effectively handled in a timely manner, thereby comprehensively improving the safety and reliability of the storage tank 1.

[0063] In order to better understand the above embodiments, the working principle of the intelligent storage device of the present invention will be further described below with reference to the accompanying drawings.

[0064] First, when the intelligent storage device is put into use, the gravity sensor 6 located at the bottom of the storage tank 1 immediately enters the working state and begins to continuously capture the subtle changes in the overall weight of the storage tank 1. This serves as a direct basis for judging the amount of carbon dioxide stored in the storage tank 1. After precise algorithm processing, it can be converted into extremely accurate liquid level information.

[0065] In addition, the display screen 10 of the intelligent storage device has a built-in information processing module. This information processing module has a built-in carbon dioxide density parameter library and takes into account the impact of temperature on density by introducing a temperature correction coefficient. This allows the information processing module to accurately calculate the remaining amount of carbon dioxide in the storage tank 1 even in the event of temperature fluctuations and to feed this information back to the external display screen 10 in real time. This process is highly automated and can achieve precise measurement of the remaining amount of carbon dioxide in the storage tank 1. The measurement data can be obtained by the staff in real time, which not only eliminates the errors and lags of manual measurement but also significantly improves the accuracy and real-time nature of the data.

[0066] When there is a demand for production or storage, the pressure in the storage tank 1 needs to be maintained within an appropriate range. Therefore, when the pressure in the storage tank 1 needs to be increased to meet specific operating conditions, the control unit integrated in the display screen 10 will automatically start and trigger the self-pressurization program. This program uses the physical properties of carbon dioxide to first perform preliminary heat exchange through the external heat exchanger 2, so that part of the liquid carbon dioxide is converted into gas, and then returns to the inside of the storage tank 1 through the designed heat exchange tube 3, forming a bottom-up pressure wave, thereby initially increasing the pressure in the storage tank 1. When the efficiency of the external heat exchanger 2 is difficult to meet the requirements, the internal heater 4 can be used for further heating to efficiently heat the remaining liquid carbon dioxide, causing it to expand and vaporize more fully. In this way, the carbon dioxide in part of the tank can be effectively vaporized through the boosting unit, realizing the self-pressurization process of the storage tank 1.

[0067] During the self-pressurization process, pressure sensor 7 is a crucial component. Its function is to constantly monitor changes in the pressure within tank 1 and compare this information with a preset pressure threshold in real time. If the pressure deviates from the safe or efficient range, the output power of heater 4 or the opening of electric valve 5 on heat exchange tube 3 will be immediately adjusted to ensure that the pressure is always maintained at the optimal level. If pressure sensor 7 detects that the carbon dioxide pressure within tank 1 is too high, it immediately triggers an alarm mechanism, issuing a high-pressure gas alarm, shutting down the pressurization unit, and simultaneously opening safety valve 9 to relieve the pressure.

[0068] Throughout the CO2 output process, both liquid level changes and pressure fluctuations are digitally displayed to the operator via display screen 10. This intuitive and accurate monitoring method not only improves operational convenience but also provides valuable real-time data support for troubleshooting and performance optimization.

[0069] Based on IoT technology, the intelligent storage device, in conjunction with a remote terminal, enables remote monitoring and intelligent management of storage tank 1. By integrating advanced components such as gravity sensor 6, pressure sensor 7, heater 4, heat exchanger 2, and display screen 10, it enables comprehensive monitoring and intelligent control of key parameters such as carbon dioxide content, pressure, and temperature within storage tank 1. Its high degree of automation, precise data processing, and real-time information feedback provide strong technical support for the safe operation and efficient management of storage tank 1.

[0070] In summary, the beneficial effects of the intelligent storage device of the present invention include:

[0071] The intelligent storage device of this utility model abandons the traditional U-tube liquid level measurement method in terms of metering, and instead adopts a combination of high-precision gravity sensors and advanced data processing algorithms to achieve real-time and accurate monitoring of the remaining amount of carbon dioxide in the storage tank. In terms of carbon dioxide pressurization, a self-pressurization mechanism is innovatively introduced. By heating part of the liquid carbon dioxide to gasify and expand it, the pressure in the storage tank is naturally increased, which not only reduces energy consumption but also simplifies the operation process. At the same time, the intelligent storage device realizes remote monitoring and safety assurance through the display screen and in conjunction with the remote terminal. It can monitor the operating status of the storage tank in real time and respond quickly in abnormal situations to ensure the safe and stable operation of the storage tank. This series of technological innovations not only simplifies the operating process and improves production efficiency, but also effectively reduces energy consumption costs. It sets a new benchmark for the automated management of carbon dioxide storage tanks and promotes the green and efficient development of industrial fields such as oil and gas fields.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
