Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas leakage monitoring, and particularly relates to a storage tank leakage simulation testing device and system. BACKGROUND

[0002] The monitoring of combustible gas leakage is an important part of industrial facility safety and environmental protection. In particular, in the oil, chemical, mineral and public utility industries, many facilities use or store various combustible gases. Due to the strong volatility of these gases, once leakage occurs, not only can it cause significant damage to equipment, but also can pose a serious threat to the safety of workers, so gas leakage monitoring experiments need to be conducted to improve the monitoring ability of combustible gas leakage.

[0003] At present, gas sensors are mainly installed on storage tanks storing oil and gas, and then the gas sensors are used to detect oil and gas leakage.

[0004] However, when conducting gas leakage detection experiments on storage tanks in actual industrial scenarios, oil and gas leakage cannot be controlled, the experimental precision is poor, and the safety is poor. Moreover, the gas sensors on the storage tanks storing oil and gas are often randomly installed. When the leakage point of the storage tank is far away from the gas sensor, the gas sensor can only detect oil and gas leakage when the storage tank leaks a large amount of oil and gas, resulting in poor detection effect of the gas sensor, thereby increasing the risk of oil and gas leakage.

DETAILED DESCRIPTION

[0027] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a 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 persons skilled in the art without creative labor should fall within the scope of protection of the present application.

[0028] Figure 1 is a structural schematic diagram of a tank leakage simulation test device 01 provided by the present application, which comprises a gas generation module 101, a gas leakage simulation module 102, a gas discharge module 103 and a plurality of test gas detection modules 104.

[0029] Among them, the gas generation module 101 and the gas discharge module 103 are connected with the gas leakage simulation module 102, and the plurality of test gas detection modules 104 are installed on the outer wall of the gas leakage simulation module 102, and each test gas detection module 104 is located at a different position on the outer wall of the gas leakage simulation module 102.

[0030] The gas generation module 101 is used to generate leakage test gas and deliver the leakage test gas to the gas leakage simulation module 102.

[0031] The gas leakage simulation module 102 comprises a plurality of leakage simulation combinations 21, each leakage simulation combination 21 comprises a simulation leakage port 221 and a corner down pressure cylinder 222 connected with each other, and each simulation leakage port 221 is connected with a corner down pressure cylinder 222.

[0032] The corner down pressure cylinder 222 is used to open the simulation leakage port 221 connected with the corner down pressure cylinder 222, so that the leakage test gas leaks through the simulation leakage port 221.

[0033] The test gas detection module 104 is used to detect the leakage test gas after the leakage of the leakage test gas, and record the gas leakage detection time, so that the staff can obtain the best combination mode of the plurality of test gas detection modules 104 according to the gas leakage detection time of each test gas detection module 104 corresponding to each leakage test after a plurality of leakage tests.

[0034] Among them, the simulation leakage ports 221 corresponding to a plurality of leakage tests are different, and the gas leakage detection time corresponding to the best combination mode of the plurality of test gas detection modules 104 in each leakage test is the shortest.

[0035] The gas discharge module 103 is used to discharge the leakage test gas.

[0036] Specifically, the gas generation module 101 generates the gas for the leakage test, which generates the required leakage test gas through specific chemical reactions, physical methods or other technical means, and delivers it to the gas leakage simulation module 102 through pipes or other delivery methods. The gas generation module 101 is connected to the gas leakage simulation module 102 to ensure that the generated leakage test gas can smoothly enter the gas leakage simulation module 102, providing a gas source for subsequent leakage simulation experiments. The gas leakage simulation module 102 includes multiple leakage simulation combinations 21, each of which is composed of a simulation leakage port 221 and a corner down pressure cylinder 222 connected to each other, and each simulation leakage port 221 is connected to a corner down pressure cylinder 222. The gas leakage simulation module 102 is connected to the gas generation module 101 on the one hand to receive the leakage test gas from the gas generation module 101, and on the other hand to the gas export module 103 to discharge the leakage test gas after the experiment is completed. A plurality of test gas detection modules 104 are also installed on the outer wall of the gas leakage simulation module 102 for detecting the leakage of the leakage test gas.

[0037] The simulation leakage port 221 is used to simulate the actual tank leakage situation, so that the leakage test gas can leak out through these simulation leakage ports 221, thereby providing a detection object for the test gas detection module 104. The corner down pressure cylinder 222 opens the simulation leakage port 221 connected thereto through its action, thereby controlling the leakage process of the leakage test gas. Through the driving of the corner down pressure cylinder 222, the opening and closing of each simulation leakage port 221 can be accurately controlled, realizing independent operation of a single simulation leakage port 221 or synchronous control of multiple simulation leakage ports 221, that is, according to the experimental requirements, the opening of a single simulation leakage port 221 or the simultaneous opening of multiple simulation leakage ports 221 can be accurately controlled, realizing the simulation of different gas leakage scenarios.

[0038] A plurality of test gas detection modules 104 are respectively installed at different positions on the outer wall of the gas leakage simulation module 102, and the test gas detection module 104 is used to detect the distribution of the leakage test gas after leakage and record the gas leakage detection time. For example, the test gas detection module 104 can be a gas sensor. The staff can analyze the detection effect of different positions according to the gas leakage detection time recorded by the test gas detection module 104 at different positions in each leakage test, so as to determine the best combination mode of the multiple test gas detection modules 104 after multiple leakage tests. This best combination mode means that in each leakage test, the gas leakage detection time of each test gas detection module 104 corresponding to the leakage situation of different simulation leakage ports 221 is the shortest time, so as to realize rapid and accurate detection of the leakage gas.

[0039] The gas discharge module 103 is used to discharge the leakage test gas, ensure that the gas in the gas leakage simulation module 102 can be effectively removed after the experiment, and prepare for the next experiment, and also ensure the safety of the experimental environment. The gas discharge module 103 is connected with the gas leakage simulation module 102, and the leakage test gas is discharged from the gas leakage simulation module 102 through the discharge device inside the gas discharge module 103.

[0040] During the experiment, the gas generation module 101 generates the leakage test gas and delivers it to the gas leakage simulation module 102. In the gas leakage simulation module 102, according to the experimental requirements, the corresponding simulation leakage port 221 is opened by the corner down pressure cylinder 222 to control the leakage test gas to leak out through the simulation leakage port 221. A plurality of test gas detection modules 104 installed on the outer wall of the gas leakage simulation module 102 detect the leakage test gas and record the gas leakage detection time. The workers analyze the detection effect of different test gas detection modules 104 according to the results of multiple leakage tests, and determine the best test gas detection module 104 combination mode. After the experiment, the gas discharge module 103 discharges the leakage test gas, and completes the entire leakage simulation test process.

[0041] Exemplary, Figure 2 is an exemplary structural schematic diagram of the storage tank leakage simulation test device 01 provided by the present application. The gas generation module 101 and the gas leakage simulation module 102 are both internal structures of the storage tank, and the gas discharge module 103 is a pipeline connected to the outside of the storage tank. The gas generation module 101 generates the leakage test gas and delivers it to the gas leakage simulation module 102. In the gas leakage simulation module 102, according to the experimental requirements, the leakage test gas is discharged through the simulation leakage port 221. After the experiment, the gas discharge module 103 discharges the leakage test gas, and completes the entire leakage simulation test process.

[0042] The scheme of the present application, the tank leakage simulation test device comprises a gas generation module, a gas leakage simulation module, a gas export module and a plurality of test gas detection modules; wherein, the gas generation module and the gas export module are connected with the gas leakage simulation module, a plurality of test gas detection modules are installed on the outer wall of the gas leakage simulation module, and each test gas detection module is located at a different position on the outer wall of the gas leakage simulation module; the gas generation module is used for generating leakage test gas and conveying the leakage test gas to the gas leakage simulation module; the gas leakage simulation module comprises a plurality of leakage simulation combinations, each leakage simulation combination comprises a simulation leakage port and a corner down pressure cylinder connected with each other, and each simulation leakage port is connected with a corner down pressure cylinder; the corner down pressure cylinder is used for opening the simulation leakage port connected with the corner down pressure cylinder, so that the leakage test gas leaks through the simulation leakage port; the test gas detection module is used for detecting the leakage test gas after the leakage and recording the gas leakage detection time, so that the worker obtains the best combination mode of the plurality of test gas detection modules according to the gas leakage detection time of each test gas detection module corresponding to each leakage test after a plurality of leakage tests; wherein, the simulation leakage ports corresponding to the plurality of leakage tests are different, and the gas leakage detection time corresponding to the best combination mode of the plurality of test gas detection modules in each leakage test is the shortest; the gas export module is used for discharging the leakage test gas. That is, the scheme of the present application, on the one hand, the corner down pressure cylinder opens the simulation leakage port connected with the corner down pressure cylinder, so that the leakage test gas leaks through the simulation leakage port, which can flexibly control the oil and gas leakage, improve the experimental precision and experimental safety. On the other hand, the gas generation module and the gas leakage simulation module simulate the gas leakage, and the test gas detection module detects the leakage gas after the gas leakage, so as to obtain the best combination mode of the plurality of test gas detection modules according to the gas leakage detection time of the test gas detection module, so as to realize the fastest detection of the leakage condition of each leakage point, thereby avoiding the poor detection effect of the test gas detection module when the leakage point of the tank is far away from the test gas detection module, and further reducing the risk degree of oil and gas leakage.

[0043] Figure 3 Another structural schematic view of the tank leakage simulation test device 01 provided by the present application. On the basis of the above embodiment, the gas generation module 101, the gas leakage simulation module 102 and the gas export module 103 in the tank leakage simulation test device 01 are refined.

[0044] Optionally, the gas leakage simulation module 102 further comprises a sealing plate 22. A plurality of leakage simulation combinations 21 are uniformly distributed on the sealing plate 22. The sealing plate 22 is used to avoid the leakage of the leakage test gas from the positions other than the simulation leakage port 221.

[0045] Specifically, the gas leakage simulation module 102 further comprises a sealing plate 22, which is located in the middle of the gas leakage simulation module 102 and connected with the shell of the gas leakage simulation module 102 to ensure that the leakage test gas does not leak from a position other than the simulation leakage port 221, thereby increasing the accuracy of the experiment. A plurality of leakage simulation combinations 21 are uniformly distributed on the sealing plate 22, that is, the leakage simulation combinations 21 are uniformly distributed on the sealing plate 22, the simulation leakage port 221 is a port on the sealing plate 22 and is connected with the corner pressing cylinder 222, so that when the corner pressing cylinder 222 is opened, the simulation leakage port 221 is opened, and the leakage test gas leaks from the simulation leakage port 221.

[0046] Exemplarily, Figure 4 is an exemplary structural schematic diagram of the sealing plate 22 of the storage tank leakage simulation test device 01 provided by the present application, as Figure 4 shown, the sealing plate 22 is uniformly distributed with 16 simulation leakage ports 221, and each simulation leakage port 221 is connected with the corner pressing cylinder 222. When the corner pressing cylinder 222 is opened, the simulation leakage port 221 is opened, and the leakage test gas leaks from the simulation leakage port 221.

[0047] Exemplarily, Figure 5 is an exemplary structural schematic diagram of the gas leakage simulation module 102 of the storage tank leakage simulation test device 01 provided by the present application, as Figure 5 shown, the gas leakage simulation module 102 is provided with two layers of sealing plates 22, and each layer of sealing plate 22 is provided with 16 simulation leakage ports 221, and each simulation leakage port 221 is connected with the corner pressing cylinder 222. When the corner pressing cylinder 222 is opened, the simulation leakage port 221 is opened, and the leakage test gas leaks from the simulation leakage port 221. The outer wall of the gas leakage simulation module 102 is provided with a gas sensor mounting port for mounting a gas sensor to detect the leakage gas. By increasing or reducing the gas sensor and changing the distribution mode of the gas sensor, the experiment is completed, and the best combination mode of the gas sensor is obtained. The flange 106 of the gas leakage simulation module 102 is used to connect the storage tank, and the wire arrangement groove 105 of the gas leakage simulation module 102 is used to arrange the internal connecting wire.

[0048] Optionally, the gas generation module 101 comprises a constant temperature water bath 11, an oil pan 13 and a constant temperature water circulating machine 12. The constant temperature water circulating machine 12 is connected with the constant temperature water bath 11 and is used to provide constant temperature water to the constant temperature water bath 11.

[0049] The constant temperature water bath 11 is used to heat the oil pan 13.

[0050] The oil pan 13 is placed on the constant temperature water bath 11, and the oil pan 13 is used to carry the test oil product, so that the constant temperature water bath 11 generates the leakage test gas after heating the oil pan 13.

[0051] Specifically, the constant-temperature water circulating machine 12 serves as the heat source supply core of the entire gas generation module 101, which can continuously provide constant-temperature hot water. Through precise temperature control technology, the output hot water temperature is ensured to always remain within the set rated temperature range, for example, within 90-100 degrees Celsius, to provide a stable heat source for the constant-temperature water bath tank 11, thereby ensuring that the test oil in the oil pan 13 can be heated under constant temperature conditions, and in turn, stably generate the leakage test gas. By being connected to the constant-temperature water bath tank 11, the constant-temperature water is delivered to the constant-temperature water bath tank 11, realizing precise control of the water temperature in the constant-temperature water bath tank 11. The constant-temperature water bath tank 11 serves as the heating platform for the oil pan 13, and the constant-temperature water inside can uniformly transfer heat to the oil pan 13 placed thereon, so that the test oil in the oil pan 13 reaches the required heating temperature, thereby promoting the test oil to volatilize and generate the leakage test gas. The constant-temperature water bath tank 11 receives the constant-temperature water provided by the constant-temperature water circulating machine 12 through the connection with the constant-temperature water circulating machine 12, ensuring that the water temperature in the water bath tank always remains constant, and providing a stable heating environment for the oil pan 13. The oil pan 13 is replaceable, facilitating replacement when different oil products are used without the need for cleaning. This design not only improves the convenience of operation, but also avoids cross-contamination between different oil products, ensuring the accuracy of experimental results. The oil pan 13 is used to carry the test oil and is placed on the constant-temperature water bath tank 11. When the constant-temperature water bath tank 11 heats the oil pan 13, the test oil in the oil pan 13 volatilizes under heat to generate the leakage test gas, providing the required test gas for subsequent leakage simulation experiments.

[0052] After the constant-temperature water circulating machine 12 is started, the water is heated to the set rated temperature and kept constant through the internal heating and temperature control system. The constant-temperature water circulating machine 12 delivers the constant-temperature water to the constant-temperature water bath tank 11, so that the water temperature in the constant-temperature water bath tank 11 reaches and remains at the set constant temperature. The oil pan 13 containing the test oil to be detected is placed on the constant-temperature water bath tank 11, and the constant-temperature water in the constant-temperature water bath tank 11 uniformly transfers heat to the oil pan 13. The test oil in the oil pan 13 begins to volatilize after being heated, generating the leakage test gas. The generated leakage test gas leaks out through the simulated leakage port 221 of the gas leakage simulation module 102 and enters the subsequent leakage simulation test link.

[0053] Optionally, the gas generation module 101 further comprises an oil pan replacement door 14, which is installed on the outer wall of the gas generation module 101 through a hinge, and is used to open and replace the oil pan 13.

[0054] Specifically, the oil pan replacement door 14 is connected to the outer wall of the gas generation module 101 through a hinge. This connection allows the replacement door to be flexibly opened and closed, making it convenient for the operator to replace the oil pan 13 as needed. In the closed state, the oil pan replacement door 14 can be tightly attached to the outer wall of the gas generation module 101, forming a good sealing effect. This sealing design can effectively prevent gas from leaking from the gap between the replacement door and the device outer wall, ensuring the airtightness of the gas generation module 101 during the experiment, thereby ensuring the accuracy of the generation and leakage simulation process of the leakage test gas.

[0055] Optionally, the gas generation module 101 further comprises a constant temperature water bath support frame 15 and a sliding rail 16.

[0056] The constant temperature water bath tank 11 is installed on the sliding rail 16, which is used for forward and backward sliding to replace the oil pan 13.

[0057] The constant temperature water bath support frame 15 is used to support the constant temperature water bath tank 11 after it is pulled out through the sliding rail 16.

[0058] Specifically, the sliding rail 16 is installed on the inner base of the gas generation module 101 and matches the bottom of the constant temperature water bath tank 11. Its track design can ensure that the constant temperature water bath tank 11 remains stable during sliding, avoiding water spilling or oil pan 13 displacement due to shaking or tilting. The sliding rail 16 provides support for the forward and backward sliding of the constant temperature water bath tank 11. Through the sliding rail 16, the operator can easily pull out or push back the constant temperature water bath tank 11 from the gas generation module 101, making it convenient to replace the oil pan 13. The constant temperature water bath support frame 15 is installed below the constant temperature water bath tank 11, and its position design allows it to accurately support the constant temperature water bath tank 11 after it is pulled out through the sliding rail 16. The constant temperature water bath support frame 15 can stably carry the constant temperature water bath tank 11 and the water inside it, ensuring that the constant temperature water bath tank 11 remains stable during the replacement of the oil pan 13, avoiding the water bath tank from being knocked over or the oil pan 13 from being damaged due to unstable support.

[0059] Optionally, the gas generation module 101 further comprises a retractable hose 17, and the constant temperature water circulating machine 12 is connected to the constant temperature water bath tank 11 through the retractable hose 17.

[0060] Specifically, the two ends of the flexible hose 17 are connected to the constant temperature water circulating machine 12 and the constant temperature water bath tank 11 respectively through quick couplings or sealing flanges. This connection method not only facilitates installation, but also ensures the sealing of the connection to prevent water leakage. The main function of the flexible hose 17 is to transport the constant temperature water generated by the constant temperature water circulating machine 12 to the constant temperature water bath tank 11. Through the connection of the hose, the constant temperature water can form a closed circulation system between the constant temperature water circulating machine 12 and the constant temperature water bath tank 11, ensuring that the water temperature in the constant temperature water bath tank 11 remains constant at all times. Since the constant temperature water bath tank 11 is installed on the slide rail 16 and needs to slide forward and backward to replace the oil pan 13, the flexible hose 17 can adapt to this sliding operation. During the extraction or return of the constant temperature water bath tank 11, the hose can freely expand and contract, and will not affect the transportation of constant temperature water due to stretching or compression, thereby ensuring the smooth operation.

[0061] After the constant temperature water circulating machine 12 is started, it heats the water to the set rated temperature through its internal heating and temperature control system and maintains it constant. The constant temperature water circulating machine 12 transports the constant temperature water to the constant temperature water bath tank 11 through the flexible hose 17. The constant temperature water enters the constant temperature water bath tank 11 through the flexible hose 17, uniformly transfers heat to the oil pan 13, and makes the test oil in the oil pan 13 volatilize to generate a leakage test gas. During the heating of the constant temperature water bath tank 11, the flexible hose 17 ensures the continuous supply of constant temperature water, and the water flow will not be interrupted even if the constant temperature water bath tank 11 is sliding. When it is necessary to replace the oil pan 13, the operator extracts the constant temperature water bath tank 11 from the inside of the gas generation module 101 through the slide rail 16. During the extraction, the flexible hose 17 can freely expand and contract to adapt to the sliding operation of the constant temperature water bath tank 11, ensuring that the transportation of constant temperature water is not affected. After the constant temperature water bath tank 11 is extracted, it is placed on the constant temperature water bath support frame 15 for oil pan 13 replacement operation. After the oil pan 13 replacement is completed, the operator pushes the water bath tank back into the gas generation module 101 through the slide rail 16. During the return, the flexible hose 17 can also freely expand and contract to ensure the continuous supply of constant temperature water until the constant temperature water bath tank 11 is completely pushed back into the device. After closing the oil pan replacement door 14, the gas generation and leakage simulation experiment can continue.

[0062] Exemplary, Figure 6 is an exemplary structural schematic diagram of the gas generation module 101 of the storage tank leakage simulation test device 01 provided by the present application, as Figure 6As shown, the gas generation module 101 includes a constant temperature water bath 11, an oil pan 13, a constant temperature water circulating machine 12, an oil pan replacement door 14, a constant temperature water bath support frame 15, a sliding rail 16, and a retractable hose 17. The oil pan 13 is placed on the constant temperature water bath 11, and the oil pan 13 is used to carry the test oil. The oil pan replacement door 14 is hingedly installed on the outer wall of the gas generation module 101, and is used to open the oil pan 13 for replacement. The constant temperature water bath 11 is installed on the sliding rail 16, which is used for forward and backward sliding to replace the oil pan 13. The constant temperature water bath support frame 15 is used to support the constant temperature water bath 11 after it is pulled out through the sliding rail 16. The constant temperature water circulating machine 12 is connected to the constant temperature water bath 11 through the retractable hose 17.

[0063] Optionally, the gas discharge module 103 includes an air duct 31 and a one-way axial flow fan 32.

[0064] The air duct 31 is connected to the gas leakage simulation module 102, and is used to make the leakage test gas leaked by the gas leakage simulation module 102 flow along the air duct 31.

[0065] The one-way axial flow fan 32 is installed at the outlet of the air duct 31, and is used to extract the leakage test gas.

[0066] Specifically, one end of the air duct 31 is tightly connected to the gas leakage simulation module 102, ensuring that the leaked test gas can smoothly enter the air duct 31. The air duct 31 can guide the leakage test gas to flow from the gas leakage simulation module 102 to the outlet of the air duct 31. It provides a clear flow path for the leakage gas, ensuring that the gas can flow in the predetermined direction, avoiding the disorderly diffusion of the gas inside the device. The design of the air duct 31 makes it easy for the leakage test gas to reach the outlet of the air duct 31, facilitating subsequent discharge or processing, and ensuring the safety and cleanliness of the experimental environment. The one-way axial flow fan 32 is installed at the outlet of the air duct 31 to extract the leakage test gas from the air duct 31. By generating negative pressure, the fan can effectively extract the gas from the inside of the air duct 31, ensuring the rapid discharge of the gas in the air duct 31. The operation of the one-way axial flow fan 32 can accelerate the discharge process of the leakage test gas, reduce the residence time of the gas inside the device, and thus improve the efficiency and safety of the experiment. And ensure that the gas can only be extracted from the inside of the air duct 31, prevent external gas from entering the air duct 31, avoid the interference of gas backflow to the experimental results, and also reduce the potential harm of external gas to the inside of the device.

[0067] Exemplary, Figure 7 is an exemplary structural schematic diagram of the gas discharge module 103 of the storage tank leakage simulation test device 01 provided by the present application, as Figure 7As shown, the gas outlet module 103 includes an air duct 31 and a unidirectional axial flow fan 32. The air duct 31 is connected with the gas leakage simulation module 102 for making the leakage test gas leaked by the gas leakage simulation module 102 flow along the air duct 31. Two unidirectional axial flow fans 32 are installed at two ends of the outlet of the air duct 31 at an angle of 45° for extracting the leakage test gas, which accelerates the gas discharge by using Bernoulli principle, shortens the operation time, and improves the experimental efficiency.

[0068] Optionally, the gas outlet module 103 further includes a unidirectional valve 33.

[0069] The unidirectional valve 33 is installed in the air duct 31 for unidirectional transmission of the gas in the air duct 31.

[0070] Specifically, the unidirectional valve 33 is installed in the air duct 31 between the gas leakage simulation module 102 and the air duct 31. This position design ensures that the leakage test gas must pass through the unidirectional valve 33 when entering the air duct 31, thereby realizing the unidirectional transmission of the gas. In the gas leakage simulation module 102, the leakage test gas leaks out through the simulation leakage port 221. The leaked test gas enters the inlet of the air duct 31, at which time the unidirectional valve 33 is in an open state to allow the gas to enter the air duct 31. The leakage test gas enters the air duct 31 through the unidirectional valve 33, and the unidirectional valve 33 ensures that the gas can only flow in one direction to prevent the gas from flowing in the opposite direction. The air duct 31 guides the leakage test gas to the outlet of the air duct 31, and the internal structure and design of the air duct 31 optimize the flow direction of the gas, reduce vortex and turbulence, and ensure smooth flow of the gas. The unidirectional axial flow fan 32 is installed at the outlet of the air duct 31 and generates negative pressure after being started to extract the leakage test gas from the air duct 31. The unidirectional valve 33 remains in the open state during the operation of the fan to ensure that the gas can be smoothly extracted through the air duct 31. The unidirectional valve 33 also prevents external gas from entering the air duct 31 to ensure that the gas in the air duct 31 does not flow in the opposite direction. After the leakage test gas is completely extracted, the air duct 31 and the fan stop working, the unidirectional valve 33 is closed, and the gas outlet process is completed. The gas inside the device is removed, ready for the next experiment, and ensures the safety and cleanliness of the experimental environment. By controlling the opening and closing of the unidirectional valve, the internal volatile gas can also be released to reduce the risk of explosion.

[0071] Exemplarily, Figure 8 is an exemplary structural schematic diagram of the unidirectional valve 33 of the storage tank leakage simulation test device 01 provided by the present application, as Figure 8 shown, the unidirectional valve 33 is installed in the air duct 31 for unidirectional transmission of the gas in the air duct 31.

[0072] For example, during a single experiment, the one-way valve 33 and the one-way axial flow fan 32 of the gas guiding-out module 103 are opened to ensure that there is no residual volatile gas inside the storage tank. The temperature of the constant temperature water circulating machine 12 is set to the required temperature for the test and preheated, for example, to 100°C. After the constant temperature water bath is preheated to the rated temperature, the oil to be tested is poured into the oil pan 13 and placed in the constant temperature water bath 11. When the temperature of the oil to be tested in the oil pan 13 reaches the rated temperature, the one-way valve 33 and the one-way axial flow fan 32 of the gas guiding-out module 103 are closed to maintain the internal seal. Wait for 10 minutes for gas evaporation, and during the waiting period, the simulated leakage port 221 remains closed. The gas sensor is installed on the gas sensor installation port, and the simulated leakage port 221 is opened by controlling the corner depression cylinder 222 according to the experimental scheme. After opening, the gas sensor data is recorded. After the experiment is completed, the one-way valve 33 and the one-way axial flow fan of the gas guiding-out module 103 are opened, and the internal oil gas volatile gas is exhausted. The above experimental process is repeated multiple times, and by controlling the variable method, different numbers and different positions of gas sensors are selected to detect the leaked gas in each experiment of a leakage port, and then different numbers and different positions of gas sensors are selected to detect the leaked gas in multiple experiments of the next leakage port. After completing all the multiple experiments of the single leakage port and the multiple experiments of the multiple leakage ports, the best combination of the multiple gas sensors that can detect the leaked gas the fastest and require the least number of gas sensors in all experiments can be obtained, that is, the best combination of the multiple test gas detection modules in the embodiment of the application. The above experiment can achieve the experimental purpose of monitoring the internal relationship between the sensor layout in the confined space and the leakage monitoring performance by using the device of the application, so as to improve the actual gas sensor layout according to the experimental results, thereby improving the efficiency and safety of the leaked gas detection.

[0073] Optionally, the storage tank leakage simulation test device 01 comprises a sealed storage tank, and the gas generation module 101 and the gas leakage simulation module 102 are located inside the sealed storage tank.

[0074] Specifically, the sealed storage tank is a closed container, which provides a closed experimental environment for the gas generation module 101 and the gas leakage simulation module 102, ensures that the leakage test gas will not leak to the external environment during the experiment, and also prevents external gas from entering the inside of the storage tank to interfere with the experimental results.

[0075] The device of the present application can effectively prevent the leakage of test gas from positions other than the simulated leakage orifice by arranging a sealing plate in the gas leakage simulation module and uniformly distributing multiple leakage simulation combinations on the sealing plate. This design ensures that gas leakage only occurs through the pre-set simulated leakage orifice, thereby more accurately simulating the actual tank leakage situation and improving the reliability of the leakage simulation and the accuracy of the experimental results. The gas generation module uses a constant temperature water bath, an oil pan, and a constant temperature water circulating machine to accurately control the heating temperature of the oil product, ensuring that the test oil product stably volatilizes at the rated temperature to generate the leakage test gas. This precise temperature control helps to simulate the leakage situation under different temperature conditions and provides more reliable experimental conditions for studying the performance of the leakage monitoring system under different working conditions. The one-way valve and one-way axial flow fan in the gas outlet module ensure that the leakage test gas can only flow unidirectionally along the air duct and be extracted. This design prevents gas backflow and external gas from entering the air duct, avoiding interference with the experimental results and further improving the accuracy and reliability of the leakage simulation.

[0076] Figure 9 is a structural schematic diagram of a tank leakage simulation test system provided by the present application, as Figure 9 shown, the tank leakage simulation test system includes an electrical cabinet 02 and a tank leakage simulation test device 01 as any of the above embodiments.

[0077] The electrical cabinet 02 is connected with the tank leakage simulation test device 01, and is used to provide circulating air to the tank leakage simulation test device 01.

[0078] Specifically, the electrical cabinet 02 is used to centrally install and manage the electrical equipment required by the tank leakage simulation test device, such as air compressors, control circuits, sensor interfaces, power modules, etc. This centralized management method facilitates the maintenance and management of the equipment, improving the reliability and maintainability of the system. The electrical cabinet 02 provides circulating air for the tank leakage simulation test device through the built-in air compressor or the externally connected air source. These air is used to ensure the normal operation of the leakage simulation module. All electrical equipment is centrally installed in the electrical cabinet 02, which can make the tank leakage simulation test device 01 not have internal circuits and all use pneumatic control to avoid the risk of explosion and ensure safety.

[0079] The tank leakage simulation test system of the present application realizes the centralized management of electrical equipment and the stable supply of pneumatic power. The connection between the electrical cabinet and the tank leakage simulation test device ensures the stability and safety of the system operation, improving the efficiency and reliability of the experiment. This design not only facilitates the maintenance and management of the equipment, but also provides a reliable experimental platform for studying the performance of the leakage monitoring system.
