Description

Technical Field

[0001] This invention relates to the field of evaporation control technology, and in particular to an automatic control system for a non-condensable gas valve during the evaporation process. Background Technology

[0002] An evaporation system is a device or system that converts a liquid into a gas through heating. It is widely used in many industrial fields. The system is usually composed of components such as an evaporator, a condenser, and a compressor. By heating the liquid, it evaporates into a gas in the evaporator, and then cools it in the condenser and converts it back into a liquid, thus realizing the conversion and recovery of heat energy. The working principle of the evaporation system is based on the cycle of evaporation and condensation. It can efficiently process water or other liquids and achieve goals such as concentration, separation, and purification. Evaporation systems play an important role in industries such as chemical, pharmaceutical, food, and seawater desalination.

[0003] In evaporation systems, non-condensable gas valves play a crucial role in controlling and regulating the flow of non-condensable gases generated during evaporation, ensuring the stability and efficiency of the evaporation process. Existing technologies have achieved precise control of non-condensable gas valves by integrating advanced components such as sensors, controllers, and actuators. However, in actual operation, manual switching of valve openings is required, especially in terms of timing, which necessitates manual coordination. Some technologies employ preset control logic and algorithms, but the parameters of evaporation systems are variable, making it difficult for preset control logics to adapt to different operating conditions. After adjusting the logic, its rationality cannot be verified. Therefore, this invention proposes an automatic control system for non-condensable gas valves during evaporation to address the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes an automatic control system for non-condensable gas valves during the evaporation process. This automatic control system uses a simulation unit to simulate the opening time, holding time, and cycle switching time of each non-condensable gas valve according to the control logic, thereby evaluating the operating parameters of the evaporation system, improving its rationality, and avoiding losses.

[0005] To achieve the objectives of this invention, the invention is implemented through the following technical solution: an automatic control system for non-condensable gas valves during evaporation, comprising a control unit, a non-condensable gas valve group, a sensor group, a DCS control unit, an analog unit, and a reporting module. The control unit is used to receive external commands, store control logic, process data, and send control signals to the non-condensable gas valve group. The non-condensable gas valve group includes multiple non-condensable gas valves, each corresponding to a different effect of the evaporator, for controlling the entry and exit of non-condensable gases. The sensor group is installed on the multiple non-condensable gas valves to detect the valve's open / closed state and feed back signals to the control unit. The DCS control unit is used to communicate with the control unit to remotely compile the control logic.

[0006] The simulation unit is used to simulate the opening time, holding time, and cycle rotation time of each non-condensable gas valve according to the compiled control logic, and to evaluate the operating parameters of the evaporation system. This is implemented through the control unit. The reporting module is used to output a parameter report after one cycle of the non-condensable gas valve group's operating control logic.

[0007] A further improvement is that the control unit includes a central processing unit, a connection interface, and a storage unit. The central processing unit is used for overall control processing of data signals of the entire system. The connection interface is used to connect the non-condensable gas valve group, the sensor group, and the DCS control unit, receive external instructions, execute control logic, and issue control signals. The storage unit is used to store the control logic compiled by the DCS control unit.

[0008] A further improvement is that the non-condensable gas valve group is an electromagnetically controlled valve group, which automatically opens and closes based on control logic to control the entry and exit of non-condensable gas, and the non-condensable gas valve group has a built-in remote control module for manual remote control operation.

[0009] A further improvement is that the sensor group includes multiple sets of open and closed position sensors, and the multiple sets of open and closed position sensors are respectively installed on multiple non-condensable gas valves. The sensor group has a built-in communication module, and the communication module communicates with the connection interface via wired data.

[0010] Further improvements include: the DCS control unit includes a communication module, a monitoring module, and an operation module. The communication module is used for wired data communication with the connection interface. The monitoring module is used to display all data collected, processed, and sent by the control unit on the terminal display. The operation module provides a human-machine interaction channel for operators to compile control logic. The monitoring module and operation module are directly connected to the operator's mobile APP for remote monitoring and remote compilation via the mobile APP.

[0011] A further improvement is that the simulation unit includes a data acquisition module, a modeling unit, and a simulation demonstration module. The data acquisition module is used to collect and store the equipment composition parameters, operating parameters, and position parameters of the evaporation system and the non-condensable gas valve group.

[0012] A further improvement is that the modeling unit is used to input the data collected by the acquisition module into the Revit software, to visualize the parameters in three dimensions, and then, based on BIM three-dimensional integration technology, to construct a three-dimensional image model using ContextCapture to obtain a simulation model.

[0013] A further improvement is that the simulation demonstration module is used to write the simulation model according to the compiled control logic, using BIM simulation methods, and perform simulation execution to simulate the opening time, holding time, and cycle rotation time of each effect non-condensable gas valve. Specifically, it includes the following simulation steps:

[0014] Set the opening time of each effect non-condensable gas valve, and after engaging the non-condensable gas valve interlock and the non-condensable gas valve automatic opening button, open the I effect non-condensable gas valve first according to the control logic relationship, wait for the valve to act, and upload the open position signal after the valve acts.

[0015] After the open signal of the first-effect non-condensable gas valve is held for a set time, the valve will automatically close. After the first effect is completed, the valve will close and wait for the valve to close signal. After the valve close signal is received, the second-effect non-condensable gas valve will be opened.

[0016] This process continues until the last valve. After the entire program has been executed once, the operation stops, and the cycle time is set for the next cycle.

[0017] A further improvement is that the simulation demonstration module has a built-in calculation algorithm to calculate the operating parameters of the evaporation system under the current simulation conditions, thereby evaluating the rationality of the control logic. After the evaluation is deemed reasonable, the control logic is output to the control unit for execution.

[0018] Further improvements are made in that the reporting module includes a report output module and a self-adjustment module. The report output module is used to output the actual operating parameters of the evaporation system and the opening and closing records of the non-condensable gas valve group as a report log after one cycle of the entire evaporation system and the non-condensable gas valve group operation control logic, and send them to the terminal display and the operator's mobile APP. The self-adjustment module is used to input the actual operating parameters of the evaporation system to the simulation unit, compare them with the simulated parameters, and use deep learning algorithms to compensate and adjust the simulated parameters.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention uses a DCS control unit to compile the control logic, and the control unit executes the control logic to the non-condensable gas valve group. The sensor group detects the opening and closing status of the valves and feeds back the signal to the control unit. Before executing the control logic, the simulation unit simulates the opening time, holding time and cycle time of each non-condensable gas valve according to the control logic, and evaluates the operating parameters of the evaporation system to improve its rationality and avoid losses.

[0021] 2. In the simulation control logic of this invention, the opening time, holding time, and cycle rotation time of each non-condensable gas valve are used as execution parameters, and the action signal of the non-condensable gas valve is used as the trigger point. In this way, multiple groups of valves are automatically driven in sequence. The entire control logic is based on one-button start-up of automatic control, which saves manual start-up time, improves the stability of the production system, reduces the number of operations by monitoring personnel, and the time and sequence are controllable, saving manpower and improving the safety of the on-site process system and personnel.

[0022] 3. After one cycle of the entire evaporation system and the non-condensable gas valve group operation control logic, this invention outputs the actual operating parameters of the evaporation system and the opening and closing records of the non-condensable gas valve group as a report log, which is convenient for operators to obtain. At the same time, the actual operating parameters are input to the simulation unit, and the simulation parameters are compensated and adjusted in conjunction with the deep learning algorithm to improve the simulation accuracy of the simulation unit.

[0024] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0025] Example 1

[0026] according to Figure 1 As shown in the figure, this embodiment proposes an automatic control system for non-condensable gas valves during evaporation, including a control unit, a non-condensable gas valve group, a sensor group, a DCS control unit, an analog unit, and a reporting module. The control unit is used to receive external commands, store control logic, process data, and send control signals to the non-condensable gas valve group. The non-condensable gas valve group includes multiple non-condensable gas valves, and the multiple non-condensable gas valves correspond to different effects of the evaporator, used to control the entry and exit of non-condensable gases. The sensor group is installed on the multiple non-condensable gas valves to detect the opening and closing status of the valves and feed back signals to the control unit. The DCS control unit is used to communicate with the control unit to realize remote compilation of control logic.

[0027] The simulation unit simulates the opening time, holding time, and cycle time of each effect's non-condensable gas valve according to the compiled control logic, evaluating the operating parameters of the evaporation system. This is implemented through the control unit. The reporting module outputs a parameter report after one cycle of the non-condensable gas valve group's control logic. In use, the DCS control unit compiles the control logic and executes it to the non-condensable gas valve group. Sensors detect the valve's open / closed status and feed back signals to the control unit. Before executing the control logic, the simulation unit simulates the opening time, holding time, and cycle time of each effect's non-condensable gas valve according to the control logic, evaluating the evaporation system's operating parameters to improve its rationality and avoid losses. The opening time and sequence of each effect's non-condensable gas valve are set through the DCS interface. The interlock and automatic open buttons are engaged to start the automatic control system. The system automatically executes the preset control logic, completing the opening, holding, and closing operations of each effect's non-condensable gas valve. The DCS interface is monitored to view the system's operating status and alarm information, ensuring normal system operation. Control parameters are adjusted or system operation is manually intervened according to production needs.

[0028] The control unit includes a central processing unit (CPU), a connection interface, and a storage unit. The CPU is used for overall system data signal processing. The connection interface connects to the non-condensable gas valve assembly, sensor assembly, and DCS control unit, receiving external commands, executing control logic, and issuing control signals. The storage unit stores the control logic compiled by the DCS control unit. The non-condensable gas valve assembly is an electromagnetically controlled valve assembly that automatically opens and closes based on control logic to control the entry and exit of non-condensable gases. The valve assembly also has a built-in remote control module for manual operation, offering versatility and convenience. The sensor assembly includes multiple open and closed position sensors, each mounted on a different non-condensable gas valve. The sensor assembly has a built-in communication module that communicates with the connection interface via wired data, used to detect the opening and closing of the non-condensable gas valves.

[0029] The DCS control unit includes a communication module, a monitoring module, and an operation module. The communication module communicates with the connection interface via wired data. The monitoring module displays all data collected, processed, and sent by the control unit on a terminal display. The operation module provides a human-machine interface for operators to compile control logic. The monitoring and operation modules are directly connected to the operator's mobile app for remote monitoring and compilation, facilitating monitoring and compilation operations for the operator.

[0030] The simulation unit includes a data acquisition module, a modeling unit, and a simulation verification module. The data acquisition module is used to collect and store the equipment composition parameters, operating parameters, and location parameters of the evaporation system and non-condensable gas valve group. The modeling unit is used to input the data collected by the acquisition module into Revit software, visualize the parameters in three dimensions, and then construct a three-dimensional image model using ContextCapture based on BIM three-dimensional integrated technology to obtain the simulation model.

[0031] The data acquisition module collects key information from the evaporation system and non-condensable gas valve assembly. This information includes, but is not limited to, equipment composition parameters (such as material, size, and model), operating parameters (such as temperature, pressure, and flow rate), and location parameters (the spatial position of the equipment within the system). The collected data is stored for subsequent modeling and analysis, ensuring accuracy and completeness. In the modeling unit, Revit software is used: Professional BIM software like Revit is used to input the data provided by the data acquisition module. Revit supports the creation of detailed architectural and structural models, and through parametric design, the model can be adjusted to adapt to different design requirements. 3D parameterization: In Revit, data is used to create a 3D model of the equipment in a virtual environment, based on its actual size, shape, and location. This process makes the originally abstract data intuitive and visual. BIM 3D integration technology: BIM-based 3D integration technology emphasizes information integration and sharing. During the modeling process, attention is paid to the completeness and consistency of the information carried by the model (such as equipment performance parameters, maintenance records, etc.). ContextCapture 3D Image Model Construction: To further enhance the realism and accuracy of the model, the modeling unit uses software like ContextCapture to construct a 3D image model. ContextCapture can process large amounts of photo or video data, generating high-precision 3D models through automatic matching and reconstruction algorithms. This step is used to supplement or validate the model built in Revit.

[0032] The simulation and verification module is used to simulate the opening, holding, and cycle times of various non-condensable gas valves by writing them into the simulation model according to the compiled control logic and applying BIM simulation methods. First, it receives and compiles user-defined control logic. This control logic specifies key parameters such as the opening, holding, and cycle times of each non-condensable gas valve to ensure that the simulation accurately reflects the actual system's operating state. BIM technology is used to deeply integrate the control logic with the 3D model. The BIM model incorporates non-geometric information such as equipment performance parameters and maintenance records, allowing the simulation to comprehensively consider various practical factors and improve the accuracy and reliability of the simulation results. In the BIM environment, the simulation and verification module drives the simulation model to perform dynamic simulation execution according to the compiled control logic. During this process, the module simulates the opening, holding, closing, and cycle times of each non-condensable gas valve, while simultaneously recording and analyzing system operating parameters such as temperature, pressure, and flow rate in real time. After the simulation is completed, the simulation and verification module performs a detailed analysis of the simulation results. The simulation process and results are presented to users intuitively through charts, animations, and other means, allowing users to clearly see the system's operating status and performance changes.

[0033] Specifically, the simulation steps include the following:

[0034] The opening time of each effect's non-condensable gas valve is set. After the non-condensable gas valve interlock and automatic opening button are activated, the control logic first opens the I-effect non-condensable gas valve, waits for valve action, and then sends an open-to-position signal. The I-effect non-condensable gas valve's open-to-position signal is held for a set time before automatically closing. After the I-effect completes its operation, the valve closes and waits for a closed-to-position signal. Once the closed-to-position signal is received, the II-effect non-condensable gas valve opens. This process continues until the last valve. After the entire procedure is executed once, operation stops, and a cycle time is set for the next cycle. The control logic and graphs are written using the DCS (Distributed Control System) to add automatic control of the non-condensable gas valves for evaporation. The start-up sequence and start-up time logic are written in the DCS control algorithm. When the operator operates the non-condensable gas switching button, the I-effect non-condensable gas valve automatically starts operating. The start-up sequence and start-up time are fully controllable. The start-up time can be extended or shortened according to the actual site conditions, and any stop operation can be removed from the start-up sequence. Cyclic control is also possible. It improves the stability of the production system, reduces the number of operations required by monitoring personnel, and simultaneously enhances the safety of the on-site process system and personnel.

[0035] The simulation and verification module incorporates a computational algorithm to calculate the operating parameters of the evaporation system under the current simulation conditions. This algorithm evaluates the rationality of the control logic. Once deemed reasonable, the control logic is output to the control unit for execution. The computational algorithm comprehensively considers various factors of the evaporation system, such as temperature, pressure, flow rate, and material concentration. Through mathematical models and physical equations, it accurately calculates the system operating parameters under the current simulation conditions. These parameters are crucial for evaluating system performance and optimizing the control logic. After obtaining the system operating parameters, the built-in computational algorithm further analyzes these parameters to evaluate the rationality of the preset control logic. The algorithm compares the simulation results with expected targets or industry standards to determine whether the control logic can effectively achieve stable system operation and efficient output. If any unreasonable aspects of the control logic are found, corresponding optimization suggestions are generated. These suggestions include adjusting control parameters, optimizing control strategies, and improving equipment configuration. After evaluating the rationality of the control logic, it is output to the control unit for execution. This process ensures the accuracy and effectiveness of the control logic in practical applications, providing strong support for the automation and intelligent control of the evaporation system.

[0036] Example 2

[0037] according to Figure 1 As shown in the figure, this embodiment proposes an automatic control system for non-condensable gas valves during evaporation, including a control unit, a non-condensable gas valve group, a sensor group, a DCS control unit, an analog unit, and a reporting module. The control unit is used to receive external commands, store control logic, process data, and send control signals to the non-condensable gas valve group. The non-condensable gas valve group includes multiple non-condensable gas valves, and the multiple non-condensable gas valves correspond to different effects of the evaporator, used to control the entry and exit of non-condensable gases. The sensor group is installed on the multiple non-condensable gas valves to detect the opening and closing status of the valves and feed back signals to the control unit. The DCS control unit is used to communicate with the control unit to realize remote compilation of control logic.

[0038] The simulation unit simulates the opening time, holding time, and cycle time of each effect's non-condensable gas valve according to the compiled control logic, evaluating the operating parameters of the evaporation system. This is implemented through the control unit. The reporting module outputs a parameter report after one cycle of the non-condensable gas valve group's control logic. In use, the DCS control unit compiles the control logic and executes it to the non-condensable gas valve group. Sensors detect the valve's open / closed status and feed back signals to the control unit. Before executing the control logic, the simulation unit simulates the opening time, holding time, and cycle time of each effect's non-condensable gas valve according to the control logic, evaluating the evaporation system's operating parameters to improve its rationality and avoid losses. The opening time and sequence of each effect's non-condensable gas valve are set through the DCS interface. The interlock and automatic open buttons are engaged to start the automatic control system. The system automatically executes the preset control logic, completing the opening, holding, and closing operations of each effect's non-condensable gas valve. The DCS interface is monitored to view the system's operating status and alarm information, ensuring normal system operation. Control parameters are adjusted or system operation is manually intervened according to production needs.

[0039] The reporting module includes a report output module and a self-adjustment module. The report output module outputs the actual operating parameters of the evaporation system and the opening / closing records of the non-condensable gas valve group as a report log after one cycle of the entire evaporation system and non-condensable gas valve group operation control logic. This log is sent to the terminal display and the operator's mobile app. The self-adjustment module inputs the actual operating parameters of the evaporation system into the simulation unit, compares them with the simulated parameters, and uses deep learning algorithms to compensate and adjust the simulated parameters. After a complete cycle of the entire evaporation system and non-condensable gas valve group operation control logic, the report output module automatically collects and organizes the actual operating data of the system. This includes, but is not limited to, key operating parameters of the evaporation system such as temperature, pressure, flow rate, and material concentration, as well as the opening / closing records of the non-condensable gas valve group. This data is output through multiple channels to ensure that operators can obtain the latest operating status information of the system anytime, anywhere, facilitating timely understanding of system performance, identification of potential problems, and appropriate decision-making. The self-adjustment module inputs the actual operating parameters of the evaporation system into the simulation unit in real time or periodically, and performs detailed comparative analysis with the simulated parameters obtained through the simulation verification module. This verifies the accuracy and reliability of the simulation model. Based on comparative analysis, deep learning algorithms are used to intelligently compensate and adjust the simulation parameters. Deep learning algorithms possess powerful data processing and pattern recognition capabilities, automatically identifying the differences between simulated and actual parameters and the underlying patterns, thereby generating more accurate simulation parameters that better reflect reality. These optimized simulation parameters are then reapplied to the simulation model, inferring the adjustment values. Through continuous iteration and optimization, the control logic of the evaporation system and non-condensable gas valve group gradually becomes more refined, significantly improving the overall system performance and operating efficiency. Simultaneously, this self-optimization and continuous improvement capability enables the system to better adapt to changes in the external environment and fluctuations in internal conditions, maintaining a long-term stable operating state.

[0040] The automatic control system for non-condensable gas valves in this evaporation process uses a DCS control unit to compile the control logic. The control unit executes the control logic to the non-condensable gas valve group. Sensors detect the valve's on / off status and feed back signals to the control unit. Before executing the control logic, a simulation unit simulates the opening time, holding time, and cycle time of each non-condensable gas valve according to the control logic, evaluating the operating parameters of the evaporation system to improve its rationality and avoid losses. Furthermore, in the simulated control logic, this invention uses the opening time, holding time, and cycle time of each non-condensable gas valve as execution parameters and the non-condensable gas valve action signal as the trigger point, thus automatically driving multiple valve groups sequentially. The entire control logic uses one-button automatic start as a benchmark, saving manual start-up time, improving the stability of the production system, reducing the number of operations required by monitoring personnel, and ensuring controllable timing and sequence, saving manpower, and improving the safety of the on-site process system and personnel. Meanwhile, after the entire evaporation system and non-condensable gas valve group operation control logic completes one cycle, the actual operating parameters of the evaporation system and the opening and closing records of the non-condensable gas valve group are output as a report log for easy access by operators. At the same time, the actual operating parameters are input to the simulation unit, and the simulation parameters are compensated and adjusted in conjunction with deep learning algorithms to improve the simulation accuracy of the simulation unit.
