Description

Technical Field

[0001] The present invention specifically relates to a uranium hexafluoride conversion simulation platform, method and system. Background Art

[0002] The GFX conversion process is called the "one-step dry process", which uses a converter to directly convert uranium hexafluoride into uranium trioxide powder. The process is as follows: Figure 1 As shown: UF6 gas and water vapor that meet the process requirements undergo gas phase hydrolysis reaction in the reaction chamber to generate feather-like UO2F2 particles and HF gas. UO2F2 powder settles naturally and falls to the bottom of the reaction chamber, and is sent to the converter by the screw conveyor at the bottom of the reaction chamber, where it undergoes a reduction and defluorination reaction with the water vapor entering from the tail of the furnace to produce U3O8 powder, which is discharged from the tail of the furnace and discharged through a cooling screw discharge device.

[0003] Establishing a control simulation platform for uranium hexafluoride conversion devices, exploring ways to improve the stability of flow control and material ratio accuracy of uranium hexafluoride conversion devices, and providing references for the design and optimization of control methods for actual industrial devices have far-reaching practical significance. However, the simulation platform for uranium hexafluoride conversion devices currently has the following problems:

[0004] 1. The uranium hexafluoride conversion process uses a distributed micromechanism model, which takes a long time to calculate and is difficult to achieve real-time simulation and data display;

[0005] 2. The data at different locations inside the reactor are very abstract, making it difficult to intuitively represent the state of the reaction;

[0006] 3. The simulation process requires interaction between multiple platforms, and thread communication and control are complex. Summary of the invention

[0091] The uranium hexafluoride conversion simulation platform of this embodiment is written based on Java language, and the blocking queue is ArrayBlockingQueue provided under the java.util.concurrent package.

[0092] The uranium hexafluoride conversion simulation platform of this embodiment realizes data communication between the Java platform and multiple special software by designing a cross-platform interactive module, which utilizes the API interface between the corresponding software (the first simulation calculation software and the second simulation calculation software) and Java.

[0093] Among them, the first simulation calculation software 200 is a special software capable of simulating the control system, such as MATLAB. The second simulation calculation software 300 is a special software capable of dynamically simulating the chemical process, such as Comsol. The Comsol platform includes a reaction chamber module and a converter module to calculate the mechanism model. The Matlab platform includes SimScape physical model, conventional control module, and advanced control module to calculate the controller.

[0094] In this embodiment, the slave thread layer 2 includes a control system module 21, a reaction chamber module 22 and a converter module 23.

[0095] The main thread layer 1 is used to output simulation parameters related to the reaction chamber controller model to the control system module 21. The control system module 21 is used to call the first simulation calculation software 200 to perform simulation calculation on the reaction chamber controller model, and transmit the reaction chamber control parameters obtained by simulation to the reaction chamber module 22.

[0096] The main thread layer 1 is also used to output simulation parameters related to the reaction chamber model to the reaction chamber module 22, and the reaction chamber module 22 is used to call the second simulation calculation software 300 to perform simulation calculation on the reaction chamber model.

[0097] The main thread layer 1 is also used to output simulation parameters related to the converter controller model to the control system module 21. The control system module 21 is also used to call the first simulation calculation software 200 to perform simulation calculation on the converter controller model, and transmit the converter control parameters obtained by simulation to the converter module 23.

[0098] The main thread layer 1 is also used to output simulation parameters related to the converter model to the converter module 23, and the converter module 23 is used to call the second simulation calculation software 300 to perform simulation calculation on the converter model.

[0099] The slave thread calculates the control system module by calling Matlab, and the Comsol model calculates the reaction chamber module and the converter module, thus realizing the dynamic simulation calculation of the uranium hexafluoride conversion device. The main thread outputs the simulation parameters to the slave thread by using the blocking queue, and retrieves the simulation results of the slave thread through the blocking queue; the main thread controls the simulation calculation process of the slave thread by using the blocking queue.

[0100] In this embodiment,

[0101] The main thread layer 1 includes a data module, which includes a simulation parameter setting module 11 and a data display module.

[0102] The simulation parameter setting module 11 is used to output the simulation parameters related to the reaction chamber controller model, the simulation parameters related to the converter controller model, the simulation parameters related to the reaction chamber model and the simulation parameters related to the converter model to the slave thread layer 2 by using a blocking queue.

[0103] The data display module is used to retrieve the simulation results output from the thread layer 2 through the blocking queue for display.

[0104] As attached Figure 8 As shown, the functions of the simulation parameter setting module 11 are control strategy selection (PID and MPC can be selected, MPC is the default), PID parameter setting (when switching to PID control), material flow setting, and ratio setting between each material and the main material.

[0105] In this embodiment,

[0106] The main thread layer 1 also includes a data storage module 14, which is electrically connected between the data module and the slave thread layer 2, and is also electrically connected to the data management software 400.

[0107] The simulation parameters output by the simulation parameter setting module 11 are input to the slave thread layer 2 via the data storage module 14. The data storage module 14 is used to store the simulation parameters output by the simulation parameter setting module 11 as historical data in the data management software 400.

[0108] The simulation results output from the thread layer 2 are input to the data storage module via the data storage module 14 . The data storage module 14 is also used to store the simulation results output from the thread layer 2 as historical data in the data management software 400 .

[0109] In this embodiment,

[0110] The data display module includes a dynamic data display module 12 and a historical curve display module 13.

[0111] The dynamic data display module 12 is used to display the two-dimensional dynamic distribution diagram of the reactor output by the reaction chamber module 22 and the measurement point values ​​thereon, as well as the two-dimensional dynamic distribution diagram of the converter output by the converter module 23 and the measurement point values ​​thereon.

[0112] The data storage module 14 is used to retrieve historical data from the data management software 400 according to the instructions transmitted by the historical curve display module 13, and output the historical data to the historical curve display module 13 for display.

[0113] In this embodiment, the data management software 400 is MySQL.

[0114] The main thread implements the main interface display, control parameter setting, historical curve display, simulation log recording, historical data storage and other functions. The historical data storage function refers to the connection with the Java platform and MySQL to store the simulation data in the database.

[0115] As attached Figure 2 As shown, the data storage module 14 stores the input and output information in the simulation process as historical data in the data storage platform MySQL to facilitate subsequent data call and analysis.

[0116] like Figure 5 As shown in the figure, the dynamic data includes the measurement point value and the two-dimensional dynamic distribution diagram. The measurement point value is directly displayed at the corresponding position of the interface. The two-dimensional dynamic distribution diagram includes the reactor two-dimensional dynamic distribution diagram and the converter two-dimensional dynamic distribution diagram. Among them, the reactor two-dimensional dynamic distribution diagram is obtained by using the grid data calculated by the mechanism model, and the corresponding RGB value is calculated according to the color table, and then interpolated and softened; the converter two-dimensional dynamic distribution diagram is designed using the third-party open source package JFreeChart, attached Figure 6The two-dimensional data dynamic distribution diagram of the reactor velocity field and temperature field and the two-dimensional data dynamic distribution diagram of the converter are shown. For the situation where there are multiple physical quantities dynamically distributed at the same position, a dynamic switching function is set in the form of a drop-down box, and the user can freely select the physical quantity. Figure 7 As shown, the historical curve display includes: bit number selection, upper and lower limit settings, display of current time and current data, time axis length selection, and forward and backward flipping functions.

[0117] As attached Fig. 9 As shown, the main thread layer 1 also includes a user log module 15, which records the simulation process of the control simulation platform and the operations performed at the corresponding time from the start of the simulation, including: simulation time initialization, control strategy modification, and setting value modification.

[0118] See attached Figure 3 In this embodiment, a control module is also included.

[0119] The control module is electrically connected between the main thread layer 1 and the slave thread layer 2, and is used to determine whether the slave thread layer 2 has output simulation results after a simulation cycle ends. When the judgment result is "yes", the main thread layer 1 is controlled to retrieve the simulation results output from the slave thread layer 2 for display, and output new simulation parameters to the slave thread layer 2.

[0120] The control module is also used to determine whether the main thread layer 1 has simulation parameters output after a simulation cycle ends. When the judgment result is "yes", the control slave thread layer 2 takes out the simulation parameters output by the main thread layer 1 and performs simulation calculations.

[0121] If the main thread does not output the new simulation parameters to the corresponding blocking queue, when the slave thread completes a simulation calculation, the slave thread will "pause" because it cannot obtain data. When the main thread outputs the simulation parameters, the slave thread will obtain the data and perform simulation calculations.

[0122] In this embodiment,

[0123] The control module includes a simulation acceleration module, which is used to control the slave thread layer 2 to simulate a window length in advance by using a background calculation method to ensure the real-time performance of the data display of the main thread layer 1.

[0124] As attached Figure 4As shown in the figure, the simulation acceleration module: Since the uranium hexafluoride conversion device model adopts a distributed partial micro mechanism model, the model calculation takes a long time. How to ensure the real-time performance of the simulation is a difficult problem that needs to be solved. The solution of this simulation platform is: using the background calculation method, the slave thread simulates a window length in advance, and the window length is 30 seconds, so as to ensure the real-time performance of the main thread data display. The data currently displayed by the main thread is actually the data of the previous cycle (play queue), and the slave thread is calculating the model data at this time (the data is saved in the preparation queue). When the main thread data refresh is completed and the slave thread calculation is completed at the same time, the next calculation cycle begins, and the data calculated and saved by the slave thread is displayed (the data in the preparation queue is stored in the play queue), and the slave thread starts a new calculation. This cycle is repeated to achieve the effect of real-time refresh display.

[0125] As attached Figure 5 As shown, the array lengths of the play queue p and the reserve queue r are both 30, and one data is read per second, that is, 30 data are read per cycle. The specific process is as follows:

[0126] (1) At time t-30, the simulation obtains 30 data within 30 seconds starting from time t and stores them in the preparation queue r[t-30]~r[t-1]. The 30 data obtained by simulation at time t-60 are stored in the play queue, that is, r[t-60]~r[t-31] are stored in sequence in p[t-30]~p[t-1]. The data presented to the user at time t-30 is real-time data.

[0127] (2) At time t, the simulation obtains 30 data within 30 seconds starting from time t+30 and stores them in the preparation queue r[t]~r[t+29], and the 30 data obtained by simulation at time t-30 are stored in the play queue, that is, r[t-30]~r[t-1] are stored in sequence in p[t]~p[t+29], so the data presented to the user at time t is also real-time data;

[0128] …and so on.

[0129] Example 2

[0130] This embodiment provides a simulation method for converting uranium hexafluoride using the simulation platform of embodiment 1, referring to Figure 2 :

[0132] The first simulation calculation software 200 is called from the thread layer 2 to perform simulation calculations on the reaction chamber controller model and the converter controller model respectively, and the reaction chamber control parameters obtained by simulation are used as the simulation control parameters of the reaction chamber model, and the converter control parameters obtained by simulation are used as the simulation control parameters of the converter model.
