Description

Technical Field

[0001] The present invention relates to the field of safety engineering technology, and in particular to a hydrogen filling leakage accident simulation device, an interaction method and an application thereof. Background Art

[0002] Hydrogen energy has outstanding advantages such as convenient storage and transportation, diverse sources, and clean and environmentally friendly. Many countries regard the development of hydrogen energy as an important energy strategy.

[0003] Hydrogen has potential leakage and explosion hazards during its preparation, storage, transportation, filling and use. Hydrogen safety has become an important prerequisite for the application and large-scale commercial promotion of hydrogen energy. According to statistics, accidents at hydrogen refueling stations account for 53%. Therefore, with the accelerated construction of hydrogen refueling stations and the gradual popularization of self-service hydrogen refueling in the future, strengthening the job operation and emergency response training of hydrogen refueling station practitioners will play a positive role in reducing the occurrence of accidents and preventing accidents from expanding.

[0004] Leakage is prone to occur during the hydrogen filling process of the hydrogen refueling machine, including failure of the seal between the hydrogen refueling gun and the hydrogen refueling port of the hydrogen energy vehicle, damage to the hydrogen refueling gun hose, damage to the hydrogen refueling machine hose terminal, etc. It is of positive significance to simulate the above leakage conditions and carry out targeted emergency response training.

[0005] Traditional hydrogen refueling station job operation emergency response training mainly adopts the following methods:

[0006] (1) Book learning, that is, allowing hydrogen station staff to learn independently by referring to documents, drawings and other materials. However, this training method has the disadvantages of being single in form, detached from production practice and taking a long time to learn.

[0007] (2) Multimedia learning, that is, allowing hydrogen station staff to learn through videos, PPT, etc. Although this method is much more vivid in form, it also has the disadvantage of being out of touch with production practice.

[0008] (3) On-site internship, that is, on-site visits and learning at the equipment site under the guidance of senior employees of the hydrogen station. This training method is limited by the personal ability and explanation level of the instructors on the one hand, and is easily affected by various risk factors on the other hand and cannot be carried out frequently. In addition, the training efficiency of short-term on-site internships is not very high. Only through repeated long-term internships can the ideal training effect be truly achieved.

[0009] (4) Drills and simulations, that is, by assuming accident conditions, the participants simulate the accident handling process through narration, assumed operations and discussions. The above methods cannot truly simulate the accident status (such as leakage, etc.), and the training effect will be affected to a certain extent.

[0010] In view of the shortcomings of the traditional emergency response training methods for hydrogen refueling station operations, it is urgent to propose a hydrogen filling leakage accident simulation device, interactive method and application to realize the simulation operation training of hydrogen filling gun sealing docking, hydrogen filling and hydrogen leakage emergency response, so as to reduce the occurrence of hydrogen filling leakage accidents and reduce accident losses. Summary of the invention

[0011] In view of the shortcomings of the current emergency response training methods for hydrogen filling station job operations, the present invention proposes a hydrogen filling leakage accident simulation device, an interactive method and an application.

[0148] Example 2

[0149] In this embodiment, a hydrogen filling leakage accident simulation interactive method is proposed, which is adapted to the hydrogen filling leakage accident simulation device described in Example 1, and is used for hydrogen filling machine hose terminal damage leakage simulation, hydrogen filling gun hose damage leakage simulation and hydrogen filling port seal failure leakage simulation, such as Figure 2 As shown, the specific steps include:

[0150] Step 1: Based on the along-the-line resistance loss equation, Bernoulli equation, thermodynamic convection and heat transfer equation, and combined with the structural parameters of the hydrogen filling leakage accident simulation device, a hydrogen filling station process calculation model is constructed to realize small-scale process fluctuation simulation and leakage state simulation under normal conditions.

[0151] The process calculation model of the hydrogen refueling station is based on the switch quantity obtained by the PLC control module from the simulation object and the DCS host computer system. The instrument information is output to the DCS host computer system and the simulation object through the PLC control module via the TCP protocol and serial port protocol, forming a closed loop of control, calculation and display system.

[0152] Step 2, perform CFD simulation based on the process calculation model of the hydrogenation station, set simulation parameters according to the actual conditions of hydrogenation port seal failure, hydrogenation gun hose damage, and hydrogenation machine hose terminal damage, and construct numerical simulation models for hydrogenation port seal failure, hydrogenation gun hose damage, and hydrogenation machine hose terminal damage.

[0153] In this embodiment, CFD simulation Fluent is used to simulate and construct a numerical simulation model of hydrogenation port seal failure, a numerical simulation model of hydrogenation gun hose damage, and a numerical simulation model of hydrogenation machine hose terminal damage, such as Figure 3 to Figure 5 shown.

[0154] During the CFD simulation process, a steady-state solver was used, with hydrogen as the ideal gas model, and the calculation parameters for each form were subdivided into leakage port diameters of 5mm, 10mm, 20mm and leakage velocities of 10m / s, 50m / s, and 100m / s, for a total of six combination types. A total of 27 (9 states for each of the three forms) leakage state simulation values ​​were obtained.

[0155] Step 3, respectively use the hydrogenation port seal failure numerical simulation model, the hydrogenation gun hose damage numerical simulation model and the hydrogenation machine hose terminal damage numerical simulation model to perform hydrogenation port seal failure leakage simulation, hydrogenation gun hose damage numerical leakage simulation and hydrogenation machine hose terminal damage numerical leakage simulation to obtain simulation results of different leakage states during hydrogen filling.

During the CFD simulation, the tuning parameters of the hydrogenation port seal failure numerical simulation model, the hydrogenation gun hose damage numerical simulation model, and the hydrogenation machine hose terminal damage numerical simulation model are adjusted to simulate a variety of leakage states.

[0157] The tuning parameters include the aperture, shape, channel length of the leakage port of the leakage simulation mechanism after smoke occurs, the pressurization value of the leakage simulation mechanism pressurizing component, and the heating value of the leakage simulation mechanism heating component. By adjusting and controlling the aperture and shape of the leakage simulation mechanism pressurizing component, the leakage simulation mechanism heating component, the leakage simulation mechanism switch and the leakage port of the leakage simulation mechanism in the leakage simulation mechanism, simulation of different leakage states during hydrogen filling is achieved.

[0158] In this embodiment, the critical change condition is the relationship between the leakage state change conditions simulated by the water and alcohol mixture, that is, the possibility and change conditions of the leakage changing from one state to another. For example, the gas leakage changes from a leakage diameter of 5mm and a shooting speed of 10m / s to a leakage diameter of 20mm and a shooting speed of 100m / s, and the sequential relationship and response conditions between the various state points may be experienced in the middle.

[0161] Step 4.2, based on the simulation results of different leakage states during the hydrogen refueling process, analyze the correlation between the leakage states, construct an undirected control graph containing the key simulation nodes of the accident evolution path, and assign prior weights to the connecting edges of the key simulation nodes of each accident evolution path in the undirected control graph.

[0162] Step 4.3, initialize the process pressure and hose corrosion data, and determine whether a leakage accident occurs and the starting node of the leakage accident based on the initial pressure and corrosion data.

[0163] Step 4.4, using the graph traversal method, determine the first node of the hydrogen filling leakage accident evolution process according to the prior weights of the connecting edges of the key simulation nodes of each accident evolution path in the undirected control graph.

[0164] Step 4.5, by adjusting the aperture, shape, channel length of the leakage port of the leakage simulation mechanism in the leakage accident simulation device, as well as the pressurizing component and heating component of the leakage simulation mechanism, and using the hydrogenation port seal failure numerical simulation model, the hydrogenation gun hose damage numerical simulation model and the hydrogenation machine hose terminal damage numerical simulation model, the evolution state of the hydrogen filling leakage accident is simulated.

[0180] Example 3

[0181] In this embodiment, a hydrogen filling leakage accident emergency response drill platform is proposed. The hydrogen filling leakage accident emergency response drill platform is used in conjunction with the hydrogen filling leakage accident simulation device described in Example 1. The internal operating system adopts the hydrogen filling leakage accident simulation interactive method described in Example 2 to perform simulated operation training of hydrogen filling gun sealing docking, hydrogen filling and hydrogen leakage emergency response.

[0182] The application process of the hydrogen filling leakage accident emergency response drill platform is as follows: Figure 7 As shown, the specific steps include:

[0183] Step 1, after completing the installation of the hydrogen filling leakage accident simulation device, run the hydrogen filling leakage accident emergency response drill platform to pre-seal the operating system of the hydrogen filling leakage accident simulation interaction party, and enter the MR simulation training software interface. At this time, the system will prompt the operator to make function selections, including learning module, assessment module and query module, which are used to realize learning function, assessment function and query function.

[0184] Step 2, when the operator selects the learning module, the operator will perform cognitive training on all the operating steps in the preset training course in a single-operation mode by playing all roles. During the operation, the operator can proceed to the next step only after correctly performing the current step. During the operation, the system operator can use the help module to provide assistance and correctly perform the operating steps. After all the operations in the training course are completed, the system will record the operator's cognitive training course information as training data.

[0185] Step 3: When the operator selects the assessment module, the operator performs training assessment on some operating steps in the preset training course by playing different roles in a single-operation or multi-operation mode.

[0186] In the single-operator mode, the operator first selects a specific role and only executes the operating steps of the selected role. During the operation, the operating steps of other roles will be automatically executed and fed back by the system. After the operation is completed, the system will form an assessment record based on the operator's operation process and results and give an assessment score.

[0187] In the multi-person operation mode, different operators use different terminals to enter the same training scenario. Each operator first selects a specific role and only executes the operation steps corresponding to the role. The selected roles cooperate with each other to complete all the operation steps. After the operation is completed, the system will form an assessment record based on the operation process and results of all operators and give the assessment results.

[0188] Step 4, when the operator selects the query module, the system retrieves the operator's relevant information from the score database, queries and browses the operator's assessment records and assessment scores. At the same time, the system can also retrieve and view the assessment records and assessment scores of all operators from the score database.
