[0019] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0020] The embodiments of the present application provide a real-time monitoring method, equipment and medium for gas and liquid leakage in storage tanks. By locating the leakage point and monitoring the leakage status of different tank leakage types in earth-covered storage tanks, the technical problem in the prior art that the accuracy of leakage point positioning of earth-covered storage tanks cannot be maintained under the condition of improving the leakage concentration monitoring accuracy is solved. The leakage position of the earth-covered storage tank is quickly located and the leakage status is monitored in real time, thereby improving the safety of the earth-covered storage tank.

[0021] The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0022] Figure 1 A flow chart of a real-time monitoring method for gas and liquid leakage in a storage tank provided in an embodiment of the present application. Figure 1 As shown, a real-time monitoring method for gas and liquid leakage in a storage tank provided in an embodiment of the present application specifically includes the following steps:

[0023] Step 101: Acquire storage tank parameter data, and classify the storage tank parameter data into leakage states to obtain the storage tank leakage type.

[0024] Among them, the types of storage tank leakage include: tank leakage and connection leakage.

[0025] Specifically, the method includes: based on the tank parameter data, obtaining the tank component connection type through the tank connection type classification; wherein the tank component connection types include: welding and sealing; according to the tank component connection type, determining the tank leakage state corresponding to the tank component connection type through tank leakage judgment; matching the tank leakage state with the tank connection type to obtain the tank leakage type.

[0026] The present application classifies the tank parameter data according to the leakage status to obtain the tank leakage type, thereby achieving the classification of the leakage conditions of different positions and different functional components of the earth-covered tank, and improving the accuracy of the tank leakage status monitoring.

[0027] In the examples of the present application, detailed explanation is given by the following Example 1.

[0028] Example 1: Earth-covered storage tanks generally use a combination of welding and sealing connections. The welding part is generally on the tank body, and the sealing connection is generally used on connecting parts such as pipes, flanges, and valves.

[0029] Firstly, the inherent parameters of the storage tank are obtained, and the connection modes corresponding to different components in the storage tank are distinguished to obtain the connection types of the tank components.

[0030] Next, the leakage status classification uses the support vector machine (SVM) algorithm to classify the processed data and divide the leakage status of the storage tank into three states: normal, warning and leakage.

[0031] When it is determined to be a leakage state, the leakage type determination module determines whether it is a connection leakage or a tank body leakage according to the connection type (welding, sealing) of the storage tank.

[0032] Step 102: When the storage tank leakage type is tank body leakage, determine the tank body leakage point through phased array C scanning.

[0033] Specifically, the method includes: determining the leakage range of the tank body by calibrating the connection position of the tank body based on the leakage type of the tank; when the leakage type of the tank body is tank body leakage, performing a phased array C scan on the leakage range of the tank body to determine the scanning image of the tank body; and obtaining the leakage point of the tank body by making a critical judgment on the leakage of the tank body based on the scanning image of the tank body.

[0034] In the case where the tank leakage type is tank body leakage, the present application determines the tank body leakage point through phased array C scanning, realizes the positioning of the tank body leakage point, and improves the positioning accuracy of the tank body leakage point.

[0035] In the examples of the present application, detailed explanation is given by the following Example 2.

[0036] Example 2: Phased array C-scan technology acquires information inside a material by emitting ultrasonic waves and receiving echo signals. Its principle is based on the propagation speed of ultrasonic waves in the material, and the internal structure and defects of the material are determined by calculating the time delay and propagation speed of the echo signal. This technology uses the characteristics of the phased array probe to control the time delay of the excitation (or receiving) pulses of each element in the transducer array, and changes the phase relationship of the sound wave reaching a certain point in the workpiece, thereby achieving the deflection and focusing of the sound beam. Then, imaging is achieved by combining mechanical and electronic scanning.

[0037] First, the leakage range of the tank body is determined by calibrating the connection position of the tank body, that is, the pre-welding position calibration in the tank body manufacturing process. The leakage range of the tank body represents the range of the tank body that may be weakened due to welding or corrosion.

[0038] Then, the calibrated leakage range of the tank body is scanned by phased array C to obtain a tank body scan image. In practical applications, the critical thickness of tank body leakage is set according to the tank body parameters of the earth-covered tank.

[0039] Finally, according to the leakage criticality judgment, the part of the tank body whose thickness is lower than the critical value is determined to obtain the leakage point of the tank body.

[0040] Step 103: When the storage tank leakage type is connection leakage, a gas-liquid leakage determination is performed on a preset connection point to determine the storage tank connection leakage point.

[0041] Specifically include: based on the tank leakage type, determine the tank connection leakage point group through the tank body sealing position calibration; wherein, the tank connection leakage point group includes: valves, flange interfaces, ventilation ducts; when the tank leakage type is connection leakage, determine the leakage source of the tank connection leakage point group to obtain the tank connection leakage status; wherein, the tank connection leakage status includes: tank connection liquid leakage, tank connection gas leakage, tank connection mixed leakage; according to the tank connection leakage status, determine the tank connection leakage point.

[0042] When the tank leakage type is connection leakage, the present application determines the gas-liquid leakage at the preset connection point, determines the tank connection leakage point, locates the tank connection leakage point, and improves the positioning accuracy of the tank connection leakage point.

[0043] In the examples of the present application, this is explained in detail through the following Example 3.

[0044] Example 3: First, the leakage point group of the tank connection point is determined by calibrating the tank sealing position, that is, the sealing connection position during the use of the tank body. The tank connection leakage point group represents the points where the various connection parts of the tank may have poor sealing effect or loose connection.

[0045] Then, the leakage point group of the tank connection point is judged for gas and liquid leakage, that is, the leakage source is judged to determine whether the current point is gas leakage, liquid leakage or mixed leakage. For gas leakage, it can be directly judged by the pressure change inside the tank or the leakage sensor arranged at the corresponding point. Due to the fast fluidity and diffusion speed of gas, it is generally installed in the close part; for liquid leakage, it can be judged by chemical or physical coating, and data is collected through the image acquisition end of the Internet of Things.

[0046] Finally, the tank connection leakage point is determined according to the tank connection leakage status.

[0047] It should be noted that the data information corresponding to the tank connection leakage point includes the leakage status corresponding to each point.

[0048] Step 104: Based on the preset storage tank material type, real-time flow monitoring is performed on the tank body leakage point and / or the tank connection leakage point to obtain the tank leakage rate data.

[0049] Specifically, it includes: obtaining the current liquid level height of the storage tank, and when the type of material stored in the storage tank is a volatile liquid, performing real-time gas flow detection on the leakage points of the storage tank body and / or the leakage points of the storage tank connection above the current liquid level to determine the leakage flow of the first storage tank; performing real-time liquid flow detection on the leakage points of the storage tank body and / or the leakage points of the storage tank connection below the current liquid level to determine the leakage flow of the second storage tank, and performing delayed gas flow measurement on the leakage points of the storage tank body and / or the leakage points of the storage tank connection consistent with the current liquid level to determine the leakage flow of the third storage tank; determining the leakage rate data of the first storage tank based on the leakage flow of the first storage tank, the leakage flow of the second storage tank and the leakage flow of the third storage tank; when the type of material stored in the storage tank is a non-volatile liquid, performing real-time liquid flow detection on the leakage points of the storage tank body and / or the leakage points of the storage tank connection below the current liquid level to determine the leakage flow of the fourth storage tank, and determining the leakage rate data of the second storage tank based on the leakage flow of the fourth storage tank; obtaining the leakage rate data of the storage tank based on the leakage rate data of the first storage tank or the leakage rate data of the second storage tank.

[0050] Before real-time flow monitoring is performed on the tank body leakage point and / or the tank connection leakage point based on the preset tank storage material type to obtain the tank leakage rate data, the method also includes: based on the tank body leakage point and the tank connection leakage point, through the emergency repair route configuration, determining the first emergency repair personnel arrangement strategy; according to the first emergency repair personnel arrangement strategy, through manual emergency repair safety assessment, determining the second emergency repair personnel arrangement strategy.

[0051] Based on the preset tank storage material type, the present application performs real-time flow monitoring on the tank body leakage point and / or tank connection leakage point to obtain the tank leakage rate data, thereby realizing comprehensive monitoring and analysis of different tank leakage situations and real-time monitoring of the leakage status of the covered tank.

[0052] In the examples of the present application, a detailed explanation is given by the following Example 4.

[0053] Example 4: First, for volatile chemical liquid materials, it is necessary to obtain the current liquid level height of the storage tank. When the material type stored in the storage tank is volatile liquid, real-time gas flow detection is performed on the tank body leakage points and / or tank connection leakage points above the current liquid level to determine the leakage flow of the first tank.

[0054] The first tank leakage flow rate represents the gas leakage of the earth-covered tank above the current tank liquid level (i.e., the part without liquid leakage). Due to the inherent structure of the tank, in this partial leakage state, the tank body leakage point and the tank connection leakage point may leak separately or together.

[0055] Then, real-time liquid flow detection is performed on the tank body leakage point and / or tank connection leakage point below the current liquid level height to determine the leakage flow of the second tank, and delayed gas flow measurement is performed on the tank body leakage point and / or tank connection leakage point consistent with the current liquid level height to determine the leakage flow of the third tank.

[0056] The second tank leakage flow rate characterizes the liquid leakage of the earth-covered tank below the current tank liquid level (i.e., there is a liquid leakage part), and the third tank leakage flow rate characterizes the leakage of the earth-covered tank at the current tank liquid level (i.e., the leakage point or leakage range that may exist at the current liquid level height).

[0057] It should be noted that delayed gas flow measurement is used for the characteristics of volatile liquids. During the leakage process, the leakage point or leakage range under the current liquid level will produce mixed leakage of gas and liquid, and as the leakage continues, the liquid level will gradually decrease. Therefore, when the leakage point of the tank body and / or the leakage point of the tank connection that is consistent with the current liquid level is leaked, liquid leakage will occur first, and then gas leakage will occur. Delayed gas flow measurement is conducive to the stability and effectiveness of the data obtained from the leakage situation, and reduces the probability of useless data.

[0058] Finally, based on the leakage flow rate of the first storage tank, the leakage flow rate of the second storage tank and the leakage flow rate of the third storage tank, the leakage rate data of the first storage tank is determined.

[0059] For chemical liquid materials that are not easy to volatilize, real-time liquid flow detection is performed on the tank body leakage points and / or tank connection leakage points below the current liquid level height to determine the leakage flow of the fourth tank, and the leakage rate data of the second tank is determined based on the leakage flow of the fourth tank; based on the leakage rate data of the first tank or the leakage rate data of the second tank, the tank leakage rate data is obtained.

[0060] Step 105: Determine the tank leakage state curve based on the tank leakage rate data by monitoring the tank internal pressure.

[0061] Specifically, the method includes: obtaining a tank leakage rate curve group based on the tank leakage rate data through data smoothing; integrating the tank leakage rate curve group to obtain the tank current leakage status curve; determining the tank internal pressure change curve based on the tank internal pressure monitoring, and performing tank leakage expectation fitting between the tank current leakage status curve and the tank internal pressure change curve to determine the tank leakage status curve.

[0062] After determining the tank leakage state curve according to the tank leakage rate data through tank internal pressure monitoring, the method also includes: formulating a tank leakage pollution treatment strategy based on the tank leakage state curve; and performing pollution treatment on the tank leakage according to the tank leakage pollution treatment strategy.

[0063] This application determines the tank leakage status curve based on the tank leakage rate data and through tank internal pressure monitoring, realizes the visual analysis of the tank leakage status and the prediction of the leakage status change within a certain time range, and improves the feasibility and safety of formulating tank leakage response measures.
