Description

Technical Field

[0001] The utility model relates to the technical field of storage tank anti-seepage transformation auxiliary equipment, and more specifically, to a real-time monitoring device for the pressure of a hollow layer in a storage tank bottom plate. Background Art

[0002] Vertical storage tanks are an important piece of equipment used in the storage and transportation of oil and gas. They are widely used in various locations in the petroleum and petrochemical industries and play an important role in the storage and dispatch of oil products. Generally speaking, the design service life of vertical storage tanks is 20 years, but due to corrosion problems, some tanks may experience bottom plate corrosion and perforation in less than 20 years. Tank bottom plate corrosion is an important cause of tank failure. Large amounts of leakage caused by tearing of the tank bottom are all caused by trace amounts of leakage. The initial small amount of leakage will weaken the bearing capacity of the tank bottom foundation, and the tank bottom plate will crack under the pressure of crude oil on the tank bottom, which will cause a large amount of oil to gush out.

[0003] Some existing tank bottom plates have poor corrosion resistance and are prone to corrosion pits. Some tanks have been in service for more than 20 years, with a probability of seepage or leakage exceeding 20%. Most of these tanks are still in service, posing a significant safety hazard. However, the existing technology lacks a solution for effectively monitoring leakage points in tank bottom plates. Furthermore, during the modification of tank bottom plates, the measurement and maintenance of the pressure in the hollow layer have a direct impact on the effectiveness of the modification, but the existing technology lacks a solution for measuring the pressure in the hollow layer.

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are merely embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.

[0029] Figure 1 Figure 1 is a schematic diagram of an embodiment of the real-time monitoring device for the hollow layer pressure of the tank bottom plate provided by the present application;

[0030] Figure 2 Figure 1 is a schematic diagram of an embodiment of the real-time monitoring device for the hollow layer pressure of the tank bottom plate provided by the present application; DETAILED DESCRIPTION

[0031] The core of the present application is to provide a real-time monitoring device for the hollow layer pressure of the tank bottom plate, which can measure the hollow layer pressure in real time to provide a basis for pressure supplement, ensure that the pressure of the hollow layer is always within a normal range, thereby improving the quality of anti-seepage reconstruction and the safety during service, and prolonging the service life of the tank.

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] An embodiment of the real-time monitoring device for the hollow layer pressure of the tank bottom plate provided by the present application is shown in Figure 1. Figure 1 Figure 1 A schematic diagram of an embodiment of the real-time monitoring device for the hollow layer pressure of the tank bottom plate provided by the present application is shown in Figure 1. The device can include:

[0034] The first pipe body 1 is installed on the tank bottom plate 2, and the first end 11 is in communication with the hollow layer of the tank bottom plate 2. Specifically, the first pipe body 1 can be installed on the tank bottom plate 2 by welding, which can ensure that the installation is firm enough and will not fall off during long-term service. Of course, other connection methods such as bolt connection, clamping, and bonding can also be used according to actual needs, which are not limited herein. Moreover, the hollow layer provided on the tank bottom plate 2 is used to detect whether there is a leakage position of the tank bottom plate 2. When there is a leakage position, the hollow layer is under negative pressure relative to the atmospheric pressure. Then, the outside air will enter the hollow layer through the leakage position, resulting in an increase in the pressure in the hollow layer, that is, a decrease in the negative pressure. In this way, whether there is a leakage position can be represented by detecting the gas pressure in the hollow layer, and a fast and accurate leak detection method is provided. The first pipe body 1 can be connected to the gas guide pipe extending from the hollow layer by welding. The connection part should be sealed to avoid gas leakage from the connection part to the inside. Of course, the first pipe body 1 and the gas guide pipe can also be connected by bolt connection, which is not limited herein. ​

[0035] The first end 31 of the second tube body 3 is connected to the second end 12 of the first tube body 1. The two can be connected by welding to ensure a sealing effect, or by an integrated manufacturing process to directly obtain such a connection structure. Of course, they can also be connected by threading or clamping. A pressure replenishing interface 32 is provided on the second tube body 3. When pressure replenishment is needed, a pressure replenishing component can be connected to the pressure replenishing interface 32. For example, a vacuum pump can be used to evacuate the second tube body 3. Since it is connected to the hollow layer through the first tube body 1, the pressure in the hollow layer can be adjusted to the required negative pressure value to achieve negative pressure replenishment. After the pressure replenishment is completed, the pressure replenishing component can be disconnected from the pressure replenishing interface 32 until it is reconnected when needed next time.

[0036] The first real-time pressure monitoring component 4 has a first end 41 that is connected to the second end 33 of the second tube body 3, so that the gas pressure in the second tube body 3 can be monitored in real time. Since the second tube body 3, the first tube body 1 and the hollow layer are connected, the pressure monitored by the first real-time pressure monitoring component 4 is equivalent to the gas pressure in the hollow layer. The first real-time pressure monitoring component 4 can optionally use a device that can convert pressure changes into electrical signals, specifically a piezoresistive, piezoelectric or capacitive element, wherein the piezoresistive element detects pressure by changing the material resistance with pressure, the piezoelectric element uses the piezoelectric effect to generate an electric charge by causing the crystal to vibrate through pressure, and the capacitive element changes the capacitance value by changing the tiny cavity structure. The pressure monitoring component 4 needs to be protected by a sealing material to achieve isolation from the external environment and ensure the accuracy of pressure measurement. It also includes a signal processing circuit for amplifying, filtering and conditioning the electrical signal output by the pressure sensor. This signal processing circuit can improve the sensitivity and stability of the sensor and convert the pressure signal into the required voltage, current or digital signal. It also uses an output interface to electrically connect and transmit data with the real-time pressure data transmission component 5. The first real-time pressure monitoring component 4 can also be protected by a casing to prevent its internal components from being affected by the external environment and physical damage. It can be, but is not limited to, a metal casing, a plastic casing, etc., as long as it has corrosion resistance, waterproofness and wear resistance.

[0037] The real-time pressure data transmission component 5, the first end 51 is communicatively connected to the first real-time pressure monitoring component 4. It should be noted that, as mentioned above, the first real-time pressure monitoring component 4 can convert the pressure signal into an electrical signal, and the two can realize the transmission of the electrical signal through the output interface. The real-time pressure data transmission component 5 can be used to transmit the electrical signal representing the pressure for corresponding processing. The real-time pressure data transmission component 5 can be made of traditional cables, smart pipes or optical fibers, etc., so that the data transmission rate is high and the real-time performance is good. Of course, a wireless transmission component can also be used, such as electromagnetic wave transmission, which is more convenient to arrange and will not be easily damaged. Of course, this real-time pressure data transmission component can be selected according to actual needs, and there is no limitation here.

[0038] The pressure regulating component 6 is communicatively connected to the second end 52 of the real-time pressure data transmission component 5, so that the electrical signal representing the pressure can be transmitted to the pressure regulating component 6. The pressure regulating component 6 can be located in the control room and can have a display device so as to be monitored in real time by relevant staff. In this way, the staff can see the pressure in the hollow layer of the bottom plate of the storage tank in real time. When the real-time pressure does not meet the requirements, timely pressure replenishment can be carried out, or when a leakage is determined to occur, timely maintenance can be carried out. Moreover, the same pressure regulating component 6 can be connected to the hollow layers of the bottom plates of multiple storage tanks at the same time to realize simultaneous monitoring of multiple storage tanks, and each storage tank can also be divided into multiple areas, each area is provided with a corresponding real-time monitoring device, so that it is easy to know which part of which storage tank has a leakage problem, so that the monitoring efficiency and processing efficiency are higher.

[0039] It can be seen from the above technical solution that in the embodiment of the above-mentioned real-time monitoring device for the pressure of the hollow layer of the bottom plate of the tank provided by the utility model, since it includes a first tube body, which is installed on the bottom plate of the tank, and the first end is connected to the hollow layer of the bottom plate of the tank, and a second tube body, the first end of which is connected to the second end of the first tube body, and a pressure supplement interface is provided on it, so that when the pressure supplement component is connected, the pressure in the hollow layer of the bottom plate of the tank can be adjusted. It also includes a first real-time pressure monitoring component, the first end of which is connected to the second end of the second tube body, so that the pressure in the hollow layer of the bottom plate of the tank can be monitored. Since it also includes a real-time pressure data transmission component, the first end of which is communicated with the first real-time pressure monitoring component, and a pressure regulating component, which is communicated with the second end of the real-time pressure data transmission component, the monitored pressure in the hollow layer of the bottom plate of the tank can be transmitted using the pressure data transmission component. The pressure in the hollow layer is transmitted to the pressure regulating component to provide a basis for pressure regulation. It can be seen that the device can measure the pressure of the hollow layer of the tank bottom plate in real time to provide a basis for pressure replenishment, ensuring that the pressure of the hollow layer is always within the normal range. It can not only ensure that the pressure in the hollow layer is in a normal state at all times during the anti-seepage transformation process, so that the anti-seepage transformation process can proceed smoothly, but also monitor the pressure in the hollow layer in real time during the service of the tank. When the pressure is missing, it can be discovered in time and data support can be provided for pressure replenishment to ensure the normal service of the tank bottom plate. Moreover, when the pressure loss is serious or frequent, it is easy to discover in time to provide early reminders for leakage of the tank bottom plate, and it is easier to deal with the leakage in the early stage. It can be seen that the device can simultaneously improve the quality of the anti-seepage transformation of the tank bottom plate and the safety during the service process, thereby increasing the service life of the tank.

[0040] refer to Figure 2 , Figure 2 The figure is a schematic diagram of a specific embodiment of a device for real-time monitoring pressure of the hollow layer of the bottom plate of a storage tank. In a specific embodiment of the device for real-time monitoring pressure of the hollow layer of the bottom plate of a storage tank, a pressure supplement component 7 can also be included, which is connected to the pressure supplement interface 32 and the two are detachably connected. It should be noted that since the hollow layer needs to maintain a negative pressure state, the pressure supplement mentioned here means supplementing the negative pressure, that is, vacuuming. When the negative pressure is insufficient, a vacuuming operation is performed to increase the negative pressure to maintain the negative pressure in the hollow layer. The pressure supplement component 7 is generally a vacuum pump. Of course, other devices that can pump air can also be selected according to actual needs. The pressure supplement component 7 can be connected to the pressure supplement interface 32 by a threaded connection, and the interface can be sealed with sealant to ensure a good seal, or other optional methods can be used. There is no limitation here, as long as a sufficiently good sealing effect is guaranteed.

[0041] For further reference, Figure 2The above-mentioned pressure replenishing component 7 can have a switch unit 71, which is used to turn on or off the pressure replenishing component 7 to achieve automatic operation. Moreover, the switch unit 71 can be communicatively connected to the above-mentioned pressure regulating component 6. This pressure regulating component 6 can send an opening or closing instruction to the switch unit 71. The pressure regulating component 6 is used to open the switch unit 71 when the real-time pressure data is low, and close the switch unit 71 when the pressure is replenished to an appropriate pressure value. Specifically, when the switch unit 71 receives the opening instruction, it can open the pressure replenishing component 7 for pressure replenishment operation, and when the switch unit 71 receives the closing instruction, it can close the pressure replenishing component 7. Close the pressure replenishing component 7 to stop the pressure replenishing operation, so that there is no need for manual participation, the pressure replenishing efficiency is higher, the hollow part is always kept in a sufficient negative pressure state, and the negative pressure will not be too large, thereby ensuring that the hollow layer has a sufficiently good real-time leakage monitoring function. It should be noted that the pressure replenishing process and the alarm process do not conflict. An alarm can be issued when the pressure is less than a certain threshold, and pressure replenishment can be started at the same time. The alarm can still continue during the pressure replenishment process. If the alarm continues for more than a certain period of time, it proves that there may be a large leakage area at this time and maintenance is required. If the alarm does not exceed a certain period of time, only pressure replenishment is required and no maintenance is required.

[0042] Further reference Figure 2 The above-mentioned tank bottom hollow layer pressure real-time monitoring device may further include a pressure display component 8, which is in communication with the pressure control component 6 to display real-time pressure data. Specifically, the pressure display component 8 can be in the form of an LED display screen, which can display real-time pressure data to relevant monitoring personnel. The pressure of multiple hollow layers of multiple tanks can be displayed on a single pressure display component 8, thereby achieving simultaneous monitoring and improving monitoring efficiency.

[0043] For further reference, Figure 2 The above-mentioned real-time monitoring device for the pressure of the hollow layer of the bottom plate of the storage tank may also include a pressure alarm component 9, which is in communication with the pressure control component 6 to alarm when the pressure is low. It should be noted that when the pressure in the hollow layer is monitored to be less than a certain threshold, such as -70kpa, of course, other thresholds can be selected according to actual needs, and the pressure alarm component 9 can be used to alarm, including but not limited to pop-up interface alarm, sound alarm and flash alarm. Multiple alarm methods can be combined to allow on-site monitoring staff to promptly know the abnormal situation and deal with it in time. A remote message can also be sent to the client to alarm. If the alarm lasts too long, it proves that the leakage is serious and needs to be repaired. In this case, a certain time threshold can be set. When the alarm lasts longer than a certain time threshold, an alarm signal for maintenance reminder can be issued to make the staff pay special attention.

[0044] In each embodiment of the above-mentioned tank bottom plate hollow layer pressure real-time monitoring device, continue to refer to Figure 2 The second real-time pressure monitoring component 13 may also be mounted on the first tube body 1 and communicate with the first tube body 1. The second real-time pressure monitoring component 13 may preferably be a mechanical pressure gauge, which measures pressure through the elastic deformation of sensitive elements within the gauge (such as a Bourdon tube, diaphragm, or bellows). When pressure acts on these sensitive elements, they deform. A conversion mechanism within the gauge's movement then transmits this deformation to a pointer, causing the pointer to rotate to display the pressure. On-site workers can observe the pointer pointing to a certain reading to obtain real-time information about the gas pressure within the hollow portion of that location. This provides a clear and convenient view, facilitating on-site monitoring operations. Furthermore, data can be compared with the first real-time pressure monitoring component to verify accuracy. This provides a redundant function in the event of a malfunction, further ensuring accurate leakage monitoring of the tank floor. Furthermore, the first real-time pressure monitoring component may be a digital pressure gauge. The first tube body is welded and sealed to the tank floor, while the second tube body is threaded and sealed to the first tube body. This ensures more accurate gas pressure monitoring.

[0045] Continue to refer Figure 2 In each embodiment of the above-mentioned device for real-time monitoring pressure of the hollow layer of the bottom plate of a storage tank, the device may further include:

[0046] The first on-off piece A1 is installed on the first tube body 1 and is used to control the connection and disconnection of the gas between the first tube body 1 and the second tube body 3. It should be noted that the first on-off piece A1 can isolate the second tube body 3 and the above components. Under normal circumstances, the first on-off piece A1 is in the open state. When the second tube body 3 and other components need to be repaired or replaced, the first on-off piece A1 can be closed to ensure that the hollow layer pressure monitoring is not interrupted. At this time, the second real-time pressure monitoring component 13 can be used to monitor the pressure in real time. After the replacement or maintenance is completed, the first on-off piece A1 can be opened to achieve simultaneous monitoring of the two pressure monitoring components. It can be seen that the use of this first on-off piece A1 can make maintenance and component replacement more convenient.

[0047] Continue to refer Figure 2 In each embodiment of the above-mentioned device for real-time monitoring pressure of the hollow layer of the bottom plate of a storage tank, the device may further include:

[0048] The second on-off member A2 is installed on the second tube body 3, adjacent to the pressure replenishment interface 32, and is used to control the connection and disconnection of the pressure replenishment interface 32. In this case, when the second on-off member A2 is opened, the pressure replenishment component can be connected to start pressure replenishment, and the pressure of the hollow layer can be adjusted to -75kPa. This value can be selected according to actual needs and is not limited here. The second on-off member A2 can then be closed, and the pressure of the anti-seepage pressure-maintaining layer can be measured to observe the pressure-maintaining effect of the anti-seepage pressure-maintaining layer. If the pressure is insufficient, it indicates a leak point and construction needs to continue. If the pressure is sufficient, it indicates that the leak point no longer exists and construction is complete. This device can also be used for pressure monitoring during the service life of the tank to promptly detect any leaks.

[0049] Continue to refer Figure 2 In each embodiment of the above-mentioned device for real-time monitoring pressure of the hollow layer of the bottom plate of a storage tank, the device may further include:

[0050] The third on-off member A3 is mounted on the second tube body 3, adjacent to the second end 33 of the second tube body 3, and is used to control the connection and disconnection between the second end 33 of the second tube body 3 and the first real-time pressure monitoring component 4. It should be noted that the third on-off member A3 is used to isolate the first real-time pressure monitoring component 4. Under normal circumstances, the third on-off member A3 is in the open state. It is only closed when the first real-time pressure monitoring component 4 needs to be repaired or replaced, without affecting the normal operation of other components.

[0051] It should also be noted that the above-mentioned first on-off member A1, second on-off member A2 and third on-off member A3 can all be specifically implemented as valves. Under normal circumstances, the gas medium enters from the inlet of the valve and exits from the outlet. When the gas passage needs to be closed, the hand wheel can be turned to rotate the needle plug downward to block the passage until it is completely engaged with the needle groove, and the gas passage is closed.

[0052] In summary, the above-mentioned real-time monitoring device for the pressure of the hollow layer of the bottom plate of the tank can realize the real-time measurement and early warning of the pressure of the hollow layer pressure maintaining system of the anti-seepage transformation of the bottom plate of the tank, ensuring that a certain negative pressure state can be maintained at all times during the anti-seepage transformation construction process, which is beneficial to construction. In addition, when the pressure is lower than the normal value during the service of the tank, feedback pressure replenishment or regular pressure replenishment can be performed to ensure safety during the service process, which is convenient and fast, and easier to implement.

[0053] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
