Description

Technical Field

[0001] This application relates to the field of blast furnace ironmaking technology, and discloses a monitoring system and method for blast furnace tuyeres air volume distribution based on CFD. Background Technology

[0002] Hot blast enters the blast furnace primarily through the hot blast main duct, hot blast surround duct, air supply branch ducts, and tuyeres. The air volume and velocity at each tuyer directly determine the smelting intensity in that vortex zone. However, in reality, each tuyer is in a harsh environment of high temperature and high pressure, making it difficult for instruments to directly measure the air volume and velocity at the tuyer. Therefore, understanding the distribution of the gas flow is crucial. The hot blast system distributes hot blast to the tuyeres through the hot blast surround duct, forming the initial gas flow distribution in the tuyer vortex zone. However, due to the annular structure of the hot blast surround duct, the air flow distribution at the tuyeres is not uniform.

[0003] In recent years, to reduce pig iron costs, blast furnace smelting intensity has been continuously increased. This requires extremely high uniformity of tuyere blast volume distribution. However, smelting operations such as increasing oxygen enrichment and pulverized coal injection will exacerbate the unevenness of tuyere blast volume distribution, causing differences in the smelting environment in different areas of the blast furnace, worsening the local environment, and reducing the blast furnace's lifespan. However, current technology lacks methods or equipment for monitoring the uniformity of blast volume distribution at the blast furnace tuyeres. Summary of the Invention

[0004] This application relates to the field of blast furnace ironmaking technology, and discloses a monitoring system and method for blast furnace tuyeres air volume distribution based on CFD. It can monitor the blast furnace tuyeres air volume distribution and circumferential working uniformity, providing strong guidance for production operators to adjust upper and lower operating procedures. Simultaneously, it helps to open up the blast furnace's "black box" state, improving the blast furnace's digitalization and visualization level.

[0027] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0028] Figure 1 A schematic diagram of a CFD-based monitoring system for blast furnace tuyeres air volume distribution is shown in an embodiment of this application.

[0029] like Figure 1 As shown in this application, the monitoring system for blast furnace tuyere air volume distribution based on CFD includes: a client and a server; wherein, the client is used to acquire tuyere data of the blast furnace tuyere, send a calculation task to the server, and perform a visualization simulation display of the calculation results of the calculation task, the calculation task being obtained based on the tuyere data; the server is used to receive and process the calculation task sent by the client, and feed back the processed calculation results to the client so that the calculation results can be displayed through the client.

[0030] With the rapid development of computer science and technology, computational fluid dynamics (CFD) technology has been widely used in the iron and steel metallurgy industry. CFD technology is based on the conservation equations of momentum, energy and mass. It uses numerical methods to discretize the governing equations of the flow field onto a series of grid nodes and find their discrete numerical solutions. CFD technology can be used to simulate the detailed structure of complex flows, facilitate the optimization analysis of isolated elements, and also discover some new phenomena in flows that cannot be observed.

[0031] In this application, the monitoring system for blast furnace tuyere air volume distribution based on CFD can consist of one or more clients and one or more servers, and data can be transmitted between the clients and servers via TCP (Transmission Control Protocol).

[0032] The client can be used to obtain tuyere data from the blast furnace tuyere and generate calculation tasks based on the tuyere data. The calculation tasks can include the tuyere data. The client can send the calculation tasks to one of the servers. The server can receive the calculation tasks sent by the client, process the calculation tasks, obtain the corresponding calculation results, and feed back the processed calculation results to the client. The client can then display the calculation results to relevant personnel for viewing.

[0033] In one embodiment, the client includes a data acquisition module, a task management module, a result display module, a chart analysis module, and a result management module; wherein, the data acquisition module is used to acquire the tuyere data of the blast furnace tuyere, and the tuyere data includes at least structural dimension data and process parameter data.

[0034] In this application, the data for the blast furnace tuyere includes at least structural dimension data and process parameter data. The structural dimension data includes at least the structural data of the blast furnace tuyere such as tuyere length, tuyere diameter, and tuyere inclination angle. The process parameter data includes at least the data such as air volume and air pressure.

[0035] The on-site secondary system can acquire structural dimension data and process parameter data of the blast furnace tuyere through detection devices installed near the blast furnace tuyere at set time intervals, and store the acquired data in the on-site secondary system database. The set time interval can be 1 hour, 2 hours, or other times as needed; there are no restrictions here.

[0036] The client can transmit data with the field secondary system database via Modbus protocol or other communication protocols. The client's data acquisition module can obtain the latest stored structural dimension data and process parameter data of the blast furnace tuyeres in the field secondary system database in real time.

[0037] If the structural dimensions or process parameters of the blast furnace tuyeres are not stored in the secondary system database, they can be manually entered through the human-computer interaction page on the client side.

[0038] In one implementation, the task management module is used to generate a calculation task for the blast furnace tuyere based on the tuyere data, and to obtain the working status of each server in real time, and to allocate the calculation task and the tuyere data to a target server based on the working status of each server, wherein the target server is a server in an idle state.

[0039] In this application, the task management module can generate blast furnace tuyere calculation tasks based on the tuyere data obtained by the data acquisition module.

[0040] The task management module can also obtain the working status of all servers in the local area network. The working status of the servers can be divided into busy status and idle status.

[0041] If the task management module finds that all servers are busy, it can put the computing task into a queue and wait for an idle server. If the task management module finds that at least one server is idle, it can assign the computing task to any idle server so that the server can process the computing task in a timely manner.

[0042] It is important to note that before all servers on a local area network (LAN) can communicate with each other, server-side monitoring software can be deployed on all servers. After deployment, the servers on the LAN can communicate with each other.

[0043] In one embodiment, the server includes a task processing module, an automatic modeling module, an automatic discretization module, an automatic solution module, and a result management module; wherein, the task processing module is used to receive the calculation task and feed back the calculation results processed by the server to the client; the automatic modeling module is used to use the 3D modeling software in the server to automatically parametrically model the structural dimension data to obtain a 3D model of the blast furnace tuyeres, and to export the 3D model of the blast furnace tuyeres to obtain a first format model file.

[0044] In this application, when the server receives a computation task sent by the client, the server's task processing module can respond to the computation task sent by the client. Upon receiving the computation task from the client, the task processing module can transmit the computation task to the automatic modeling module and receive the computation results corresponding to the computation task transmitted by the result management module. It can also feed back the computation results corresponding to the computation task to the client. The computation results fed back by the server to the client can be intermediate format data, i.e., not the source code of the server's computation task, thus ensuring the confidentiality of the computation results to a certain extent and preventing unauthorized individuals from obtaining the computation results of the blast furnace tuyeres transmitted between the client and the server.

[0045] The automatic modeling module can acquire the calculation tasks transmitted by the task processing module and use local 3D modeling software on the server, such as SolidWorks and FreeCAD, to automatically parametrically model the structural dimension data of the blast furnace tuyere in the calculation task. It can obtain a 3D model of the blast furnace tuyere with a simulated size and actual size ratio of 1:1. The 3D model of the blast furnace tuyere can be exported according to the general STL (STereo Lithography) format to obtain a first format model file. The first format model file can be transmitted to the automatic discretization module. The first format model file can be a general STL format model file.

[0046] In one embodiment, the automatic discretization module is used to automatically parametrically discretize the first format model file using the three-dimensional discretization software in the server, and then export the discretized first format model file to obtain a second format model file.

[0047] In this application, after receiving the first format model file transmitted by the automatic modeling module, the automatic discretization module can use local 3D discretization software on the server, such as ICEM or Gmsh, to automatically parametrically discretize the first format model file. The discretized first format model file can then be exported according to the mesh file format supported by the CFD solver to obtain a second format model file. The second format model file can then be transmitted to the automatic solver module. The second format model file can be a mesh file supported by the CFD solver.

[0048] In one embodiment, the automatic solver module is used to automatically solve the second format model file and the process parameter data using the solver software in the server, to obtain the calculation results and solver log of the calculation task, wherein the solver software is based on CFD.

[0049] In this application, the automatic solving module can utilize local CFD solving software on the server, such as Fluent or OpenFOAM, to automatically solve the mesh files supported by the CFD solving software and the process parameter data in the calculation task, and obtain the solution results, i.e. the calculation results, as well as the solution process log.

[0050] This can be understood as follows: the physical model of the blast furnace tuyeres obtained by the automatic modeling module is broken down into individual grid points through the automatic discretization module, resulting in a first-format model file after discretization. A second-format model file is then exported, which is a grid file format supported by the CFD solving software. The automatic solving module uses the local CFD solving software on the server to automatically solve the second-format model file and process parameter data, obtaining the solution results and a solution process log of the automatic solving process.

[0051] In one embodiment, the result management module is used to store the computing task and the corresponding computing result in a database so that when processing the same computing task in the future, the computing result corresponding to the computing task can be obtained from the database.

[0052] In this application, the result management module can store the solution results and corresponding computation tasks obtained by the CFD solving software in a database, resulting in a computation task database that stores each computation task and its corresponding computation results. When the same computation task is encountered again, it is not necessary to solve the same computation task repeatedly. The corresponding computation results can be directly obtained from the computation task database and fed back to the client, thereby avoiding the repeated processing of the same computation task and maximizing the use of computer hard disk storage space and improving computational efficiency.

[0053] In one implementation, the result management module is used to receive the calculation results sent by the server system, and display the calculation results as three-dimensional visualizations or two-dimensional charts through the result display module or the chart analysis module.

[0054] In this application, the results management module can receive CFD calculation results sent by the server. The CFD calculation results can be displayed through the client's results display module or chart analysis module. The CFD calculation results can be displayed in the form of a local 3D model or a 2D chart to realize data visualization of the blast furnace tuyere data.

[0055] The CFD calculation results received by the client can be in an intermediate format, i.e., the source code of the non-server calculation results. This can keep the calculation results confidential to a certain extent and prevent other unauthorized individuals from obtaining the CFD calculation results of the blast furnace tuyeres transmitted between the client and the server.

[0056] In one implementation, the result display module is used to display the calculation results through three-dimensional visualization and to implement functions such as rotation, scaling, slicing, and subdivision. The chart analysis module is used to generate and display two-dimensional charts corresponding to the calculation results based on the calculation results.

[0057] In this application, the results display module can be used to display CFD calculation results through three-dimensional visualization, that is, to display CFD calculation results in the form of a three-dimensional model. It can also realize the functions of rotation, scaling, slicing and splitting on the three-dimensional visualization interface of CFD calculation results through human-computer interaction tools such as mouse or keyboard, which can enhance the staff's understanding of blast furnace tuyeres to a certain extent.

[0058] The results display module can use OpenGL or VTK libraries to achieve 3D visualization of CFD calculation results.

[0059] The chart analysis module can draw two-dimensional curves corresponding to CFD calculation results, or generate customized two-dimensional curves according to different application scenarios, and can also input data based on user-defined curves.

[0060] The chart analysis module can use the VTK library to display two-dimensional curves of CFD calculation results.

[0061] Based on the above system, this application also provides a CFD-based method for monitoring blast furnace tuyeres air volume distribution. Figure 2 A flowchart of a CFD-based monitoring method for blast furnace tuyeres air volume distribution is shown in an embodiment of this application.

[0062] like Figure 2 As shown, the monitoring method for blast furnace tuyeres air volume distribution based on CFD includes at least steps 210 to 250.

[0063] The following will be about Figure 2 Steps 210 to 240 are described in detail below:

[0064] In step 210, the client is used to obtain the tuyere data of the blast furnace tuyere, and a calculation task is generated based on the tuyere data.

[0065] In this application, simulation commands for the blast furnace tuyere can be obtained through the human-computer interaction page of the client. The tuyere data of the blast furnace tuyere can be obtained through the data acquisition module of the client, and the calculation task can be generated based on the tuyere data of the blast furnace tuyere using the task management module of the client.

[0066] Continue to refer to Figure 2 In step 220, the client is used to obtain the working status of each server, and the target server is determined based on the working status of each server.

[0067] In this application, the task management module of the client can be used to obtain the working status of all servers in the local area network. If the task management module finds that at least one server is in an idle state, then any server in an idle state is determined as the target server.

[0068] Continue to refer to Figure 2 In step 230, the client sends the computing task to the target server.

[0069] In this application, the client's task management module can be used to send computing tasks to a target server that is in an idle state.

[0070] Continue to refer to Figure 2 In step 240, the server receives the computing task and performs a solution process on the computing task to obtain the computing result.

[0071] In this application, the server's task processing module receives the computational tasks sent by the client. The task processing module can then transmit the computational tasks to the automatic modeling module. The automatic modeling module can automatically parametrically model the structural dimension data of the blast furnace tuyere in the computational tasks to obtain a three-dimensional model of the blast furnace tuyere. It then exports a first-format model file in the common STL format of the three-dimensional model of the blast furnace tuyere. The automatic discretization module can automatically parametrically discretize the first-format model file and export a second-format model file in the mesh file format supported by the CFD solving software. The automatic solving module can automatically solve the second-format model file and the process parameter data in the computational tasks to obtain the solution results, which are the computational results corresponding to the computational tasks.

[0072] Continue to refer to Figure 2 In step 250, the server feeds back the calculation result to the client, and the client displays the calculation result.

[0073] The server's result management module can be used to feed back the calculation results of the calculation tasks to the client. The client's result display module or chart analysis module can be used to display the calculation results, thereby realizing the data visualization of the blast furnace tuyere data. This will help operators understand the process parameters such as air volume and air pressure of the blast furnace tuyere.
