Description

Technical Field

[0002] In the daily operation of the tank farm, the pressure inside the pipelines of the storage and transportation system is affected by a variety of complex factors, such as temperature. When the outside temperature rises, the materials inside the pipelines undergo significant thermal expansion, which directly leads to a sharp increase in internal pressure. Excessive pressure can cause serious damage to pipeline valves and equipment. This damage not only disrupts the normal production order of the tank farm but may also trigger potential safety accidents, causing huge losses to personnel and property.

[0003] Currently, traditional pipeline pressure control methods mainly rely on regular manual inspections and manual valve adjustments. However, this approach has significant limitations: the timeliness of pressure control within the pipelines of tank farm storage and transportation systems is low, making it difficult to respond quickly and accurately to sudden pressure changes.

[0020] Figure 1 This is a schematic diagram of the tank farm storage and transportation system in an embodiment of this utility model. (Reference) Figure 1 As shown in the figure, an embodiment of the present invention provides a tank farm storage and transportation system, comprising: a tank body 10 for storing materials; a pump front end pipe 20, the inlet of which is connected to the outlet of the tank body 10; a loading pump assembly 30, the inlet of which is connected to the outlet of the pump front end pipe 20; a pump rear end pipe 40, which is disposed on the outlet side of the loading pump assembly 30 and is used to transport materials at the outlet of the loading pump assembly 30 to the downstream side of the loading pump assembly 30; and a return main pipe 50, the inlet of which is connected to the pump rear end pipe 40, and the outlet of the return main pipe 50. A first valve 60 is connected to the front end pipe 20 of the pump body and is located on the return main pipe 50, near the outlet of the return main pipe 50. A pressure sensor 70 is located on the return main pipe 50 or the rear end pipe 40 of the pump body and is used to detect the internal pressure of the rear end pipe 40 of the pump body. If the pressure sensor 70 is located on the return main pipe 50, it is located near the inlet of the return main pipe 50. A controller is electrically connected to the first valve 60 and the pressure sensor 70 and is used to: acquire the detection pressure of the pressure sensor 70; and control the first valve 60 to open if the detection pressure is greater than a preset pressure threshold.

[0021] In some implementations, the controller is also configured to: control the first valve 60 to close if the detected pressure is less than or equal to a preset pressure threshold.

[0022] refer to Figure 2 As shown, Figure 2 This is a first schematic diagram of the connection and arrangement of various parts of the tank farm storage and transportation system in an embodiment of the present invention. The pump rear end pipe 40 includes a first pipe 410, a second pipe 420, a third pipe 430, and a fourth pipe 440. The tank farm storage and transportation system also includes an electrostatic eliminator 80, a filter 81, a loading assembly 82, and an arm-mounted loading arm 83. The first pipe 410 is disposed between the loading pump assembly 30 and the electrostatic eliminator 80, the second pipe 420 is disposed between the electrostatic eliminator 80 and the filter 81, the third pipe 430 is disposed between the filter 81 and the loading assembly 82, and the fourth pipe 440 is disposed between the loading assembly 82 and the arm-mounted loading arm 83.

[0023] It should be noted that during normal material transport in the tank farm storage and transportation system, the material will flow sequentially through tank 10, loading pump assembly 30, static eliminator 80, filter 81, loading assembly 82, and loading arm 83. Loading pump assembly 30 includes multiple loading pumps.

[0024] refer to Figure 2 and Figure 3 As shown, Figure 3 This is a second schematic diagram showing the connection and setting positions of various parts of the tank storage and transportation system in an embodiment of the present invention. The inlet of the return main pipe 50 is set on the first pipe 410, and the pressure sensor 70 is set on the return main pipe 50 or the first pipe 410.

[0025] It should be noted that when the inlet of the return main pipeline 50 is located at the first pipeline 410 and the pressure sensor 70 is located at the return main pipeline 50, the detection of the pressure sensor 70 is the most accurate, which can improve the accuracy of pipeline pressure control in the tank area storage and transportation system.

[0026] refer to Figure 4 As shown, Figure 4 This is a third schematic diagram of the connection and setting positions of various parts of the tank storage and transportation system in an embodiment of the present invention. The inlet of the return main pipe 50 is set on the second pipe 420, and the pressure sensor 70 is set on the return main pipe 50 or the second pipe 420.

[0027] In other embodiments, the inlet of the main return pipe 50 is located on the third pipe 430, and the pressure sensor 70 is located on either the main return pipe 50 or the third pipe 430.

[0028] In some embodiments, the tank farm storage and transportation system further includes: a return branch pipe 84, the inlet of which is located between the first valve 60 and the inlet of the return main pipe 50, and the outlet of which is located between the first valve 60 and the outlet of the return main pipe 50; and a second valve 85, which is located on the return branch pipe 84.

[0029] It should be noted that if the first valve 60 malfunctions, material will be unable to flow back from the rear end pipe 40 to the front end pipe 20 of the pump body through the main return pipe 50. This means the material in the rear end pipe 40 cannot be reduced, and the excessively high internal pressure in the rear end pipe 40 cannot be effectively alleviated. Therefore, this embodiment of the invention incorporates a return branch pipe design. In the event of a failure in the main return pipe 50, adjustment can be made through the return branch pipe 84, thereby improving the reliability of pipeline pressure control in the tank farm storage and transportation system.

[0030] In some implementations, the first valve 60 is a check valve and the second valve 85 is a manual valve.

[0031] It should be noted that if the first valve 60 does not have directional limitation, material may enter the pump body's rear pipe 40 from the front pipe 20 through the return main pipe 50, especially when the equipment has stopped operating, which would disrupt the normal operation of the equipment. Therefore, this embodiment of the invention limits the first valve 60 to a one-way valve. In this case, material cannot enter the pump body's rear pipe 40 from the front pipe 20 through the return main pipe 50; material can only enter the pump body's front pipe 20 from the rear pipe 40 through the return main pipe 50, thus avoiding disruption to the normal operation of the equipment and improving the reliability of pipeline pressure control in the tank farm storage and transportation system.

[0032] In some embodiments, the tank farm storage and transportation system further includes: a first valve assembly 86, disposed on the front end pipe 20 of the pump body, and located between the inlet of the front end pipe 20 of the pump body and the outlet of the return main pipe 50.

[0033] In some embodiments, the tank farm storage and transportation system further includes: a material inlet pipe 88, the outlet of which is connected to the inlet of the tank body 10; and a second valve assembly 87 disposed on the material inlet pipe 88.

[0034] refer to Figure 2 As shown, the first valve assembly 86 includes a third valve 861, a fourth valve 862, and a fifth valve 863 located from the nearest to the farthest point from the outlet of the tank 10; the second valve assembly 87 includes a sixth valve 871, a seventh valve 872, and an eighth valve 873 located from the nearest to the farthest point from the inlet of the tank 10.

[0035] It should be noted that the first valve assembly 86 is used to control the outflow of material from the outlet of the tank 10, and the second valve assembly 87 is used to control the inflow of material into the tank 10. The third valve 861, the fifth valve 863, the sixth valve 871 and the eighth valve 873 can be manual valves, and the fourth valve 862 and the seventh valve can be pneumatic valves.

[0036] This invention focuses on pipeline safety technology in tank farms, aiming to provide a professional solution to address excessive pipeline pressure caused by rising ambient temperatures, thus preventing damage to pipeline valves and related equipment. Specifically, this system achieves efficient pressure control and safe pressure relief by adding a pressure sensor 70 to the pipeline and appropriately modifying the pipeline to include a one-way valve precisely controlled by the pressure sensor. Excessive pressure can cause serious damage to pipeline valves and equipment, disrupting normal production in the tank farm and potentially triggering safety accidents, resulting in significant losses of life and property. Therefore, this invention reduces the risk of safety accidents in the tank farm while lowering the internal pressure of the pipeline.

[0037] It should be noted that the pressure sensor 70 is precisely installed at a specific location on the pipeline, and its main function is to monitor pressure changes within the pipeline in real time and with high accuracy. The pressure sensor 70 can transmit the monitored pressure signal to the controller in a high-fidelity format. To ensure the accuracy and timeliness of the measurement, the pressure sensor 70 uses a high-precision pressure sensor, and its installation location is carefully selected, typically at locations within the pipeline where pressure changes are highly sensitive, such as bends and diameter changes. These locations can sensitively capture subtle pressure variations. The check valve is installed on the return branch pipe 84, and its opening and closing states are entirely intelligently controlled by the controller. When the pressure within the pipeline exceeds the preset working pressure, the controller receives the signal from the pressure sensor 70, processes it quickly and accurately, and issues a clear command to open the check valve. At this time, the material in the pipeline will smoothly return through the return branch, effectively reducing the pressure within the pipeline. When the pressure within the pipeline returns to the normal working pressure range, the controller will issue another command to close the check valve, restoring the pipeline to its normal operating state. The one-way valve employs a unique unidirectional flow design, ensuring that the liquid (material) can only flow in one direction within the pipeline, fundamentally preventing reverse flow. Its opening and closing actions are controlled by a controller via an advanced electromagnetic drive device, featuring rapid response and high reliability. The controller utilizes a programmable logic controller (PLC), possessing powerful computing and control capabilities. During control, after receiving the pressure signal from the pressure sensor 70, the controller digitizes the signal using a built-in algorithm. Specifically, the controller meticulously compares the processed pressure signal with a pre-set working pressure. Based on the comparison result, the controller quickly and accurately issues corresponding control commands. Furthermore, the controller allows users to flexibly set different pressure thresholds according to varying working conditions and stringent safety requirements, achieving personalized and precise system control.

[0038] It should be noted that the pressure sensor 70 features an innovative design: This embodiment of the invention not only employs a high-precision sensor but also integrates advanced internet technology and big data analytics. The pressure sensor 70 can upload real-time monitored pressure data to a cloud server. Through in-depth mining and analysis of a large amount of historical data, it can predict pipeline pressure change trends and issue early warning signals, providing a more proactive guarantee for the safe operation of the pipeline. The one-way valve has been optimized and improved: It utilizes new sealing materials and structural design, significantly improving its sealing performance and reliability. Simultaneously, the electromagnetic drive device employs advanced permanent magnet synchronous motor technology, offering higher efficiency and lower energy consumption, ensuring rapid valve response while reducing system operating costs. The controller has undergone intelligent upgrades: In addition to traditional control functions, the controller incorporates artificial intelligence algorithms such as fuzzy control and neural network control. These algorithms can automatically adjust control parameters based on real-time changes in pipeline pressure, achieving more intelligent and adaptive pressure control and improving system stability and reliability. This invention provides real-time monitoring and automatic control: Pressure sensor 70 continuously monitors the pressure within the pipeline, and the controller automatically and intelligently controls the opening and closing of the check valve based on the monitoring data. The entire process requires no manual intervention, significantly improving the safety and reliability of pipeline operation and ensuring stable system operation in various complex environments. Effective pressure relief: When the pressure within the pipeline exceeds a preset pressure threshold, the check valve opens instantaneously, allowing the liquid in the pipeline to flow back rapidly, thus quickly and effectively reducing the pressure within the pipeline. This timely pressure relief operation comprehensively protects the safety of pipeline valves and equipment, significantly reducing damage and malfunctions caused by excessive pressure and extending the service life of the equipment. Economical and practical: The system structure of this invention is simple and reasonable, with relatively low manufacturing costs, and is very convenient in terms of installation and subsequent maintenance. Compared with traditional pressure protection devices, it has a higher cost-performance ratio and is very suitable for large-scale tank farm applications. High flexibility: The controller allows users to flexibly set different pressure thresholds according to different working scenarios and strict safety requirements. This high degree of flexibility and adaptability enables the system to better meet diverse practical needs, ensuring stable and efficient operation under various complex working conditions.

[0039] It should be noted that the installation of pressure sensor 70 requires the following: First, a professional evaluation and analysis are necessary to select the most suitable installation location. Generally, priority is given to areas within the pipeline that are sensitive to pressure changes, such as bends and diameter changes. Then, using professional installation tools, the pressure sensor 70 is securely installed on the pipeline, ensuring a good seal during installation to prevent leaks. After installation, the connection lines of the pressure sensor 70 are carefully inspected to ensure stable and accurate signal transmission. One-way valve installation: A return line is precisely constructed on the pipeline. The diameter of the return line needs to be scientifically and rationally selected based on the actual flow and pressure requirements of the pipeline. The one-way valve is correctly installed on the main return line, ensuring its installation direction is accurate and its unidirectional conduction performance is good. After installation, the connection lines and electromagnetic drive device of the one-way valve are comprehensively inspected and tested to ensure normal and stable operation. Controller installation: The controller is installed in a dedicated control room or a location easily accessible for operation and maintenance. The wiring between the controller, pressure sensor 70, and one-way valve is carefully inspected to ensure accurate and timely transmission of signal transmission and control commands. The controller undergoes professional programming settings, precisely setting key parameters such as working pressure and pressure threshold according to the actual working conditions of the pipeline. System Commissioning: After system installation, comprehensive and meticulous commissioning is required. First, the pressure sensor 70 is rigorously calibrated to ensure accurate and reliable pressure measurements. Then, based on the actual operating conditions of the pipeline, the controller's parameters are precisely set, reasonably defining the working pressure and pressure threshold. Next, simulating a pipeline pressure exceeding the working pressure, the opening and closing functions of the check valve are tested to check the system's response speed and reliability. During commissioning, parameters need continuous optimization and adjustment until the system can operate stably and accurately. System Operation and Maintenance: During daily system operation, a comprehensive and regular maintenance mechanism needs to be established, conducting comprehensive and meticulous inspections and maintenance of the pressure sensor 70, check valve, and controller. For the pressure sensor 70, the accuracy of its measured values ​​needs to be checked regularly, calibrated by comparison with a standard pressure source to ensure that its measurement error is within the allowable range. For the check valve, its opening and closing flexibility and sealing performance must be checked to prevent leakage or jamming. For the controller, its stable operation must be checked, including the running status of the hardware and the execution of the software program. Regular cleaning and maintenance of the system are also necessary to remove dust, debris, and other factors that may affect its normal operation. Furthermore, detailed system operation logs should be established, recording system operating parameters, fault occurrence times, and handling information to promptly identify and effectively address potential problems. Regarding the controller's computation, the Programmable Logic Controller (PLC) employs an efficient scan-cycle operation method. The PLC continuously cycles through three stages: input sampling, program execution, and output refresh.During the input sampling phase, the PLC reads the pressure signal from pressure sensor 70 and stores it in the input image register. During the program execution phase, the PLC performs logical operations and comparisons on the pressure signal in the input image register according to the pre-written program, and stores the results in the output image register. During the output refresh phase, the PLC transmits the control instructions from the output image register to the electromagnetic drive of the check valve, controlling the opening and closing of the check valve. This scan-cycle operation method ensures that the controller responds quickly and accurately to pressure changes, guaranteeing the system's real-time performance and stability.

[0040] This utility model provides a tank farm storage and transportation system, including: a tank body 10 for storing materials; a pump front end pipe 20, the inlet of which is connected to the outlet of the tank body 10; a loading pump assembly 30, the inlet of which is connected to the outlet of the pump front end pipe 20; a pump rear end pipe 40, located on the outlet side of the loading pump assembly 30, for conveying materials at the outlet of the loading pump assembly 30 downstream of the loading pump assembly 30; and a return main pipe 50, the inlet of which is connected to the pump rear end pipe 40, and the outlet of which is connected to the pump... The front end pipe 20 of the pump body is connected; the first valve 60 is set on the return main pipe 50 and is close to the outlet of the return main pipe 50; the pressure sensor 70 is set on the return main pipe 50 or the rear end pipe 40 of the pump body, and is used to detect the internal pressure of the rear end pipe 40 of the pump body; wherein, if the pressure sensor 70 is set on the return main pipe 50, the pressure sensor 70 is close to the inlet of the return main pipe 50; the controller is electrically connected to the first valve 60 and the pressure sensor 70, and the controller is used to: obtain the detection pressure of the pressure sensor 70; if the detection pressure is greater than the preset pressure threshold, control the first valve 60 to open. If the detected pressure exceeds the preset pressure threshold, it indicates that the internal pressure of the pump body's rear pipeline 40 is too high. At this time, the first valve 60 is opened, and the material will flow back from the pump body's rear pipeline 40 to the pump body's front pipeline 20 through the return main pipeline 50. This reduces the material in the pump body's rear pipeline 40, thereby reducing the internal pressure of the pump body's rear pipeline 40. This avoids delays caused by manual control and improves the timeliness of pressure control in the pipelines of the tank storage and transportation system.
