Abstract
Description
Technical Field
[0001] This invention relates to the field of automated control technology for industrial evaporation and concentration processes, specifically to an intelligent evaporation and concentration control method, system, equipment, and storage medium. Background Technology
[0002] Most existing automated control systems for evaporation and concentration employ fixed parameter or fixed-range control strategies. The control logic typically relies on a single monitored variable, such as adjusting steam valves based on evaporation temperature differences or controlling material pump flow based on liquid level signals. However, under different materials, concentration stages, and equipment load conditions, the evaporation process exhibits significant nonlinear changes, making single-variable control prone to problems such as control lag, untimely adjustments, and inaccurate segment switching. Furthermore, since the evaporation process usually involves multiple stages such as heating, steady-state evaporation, devolatilization, and concentration, the conditions for determining each stage often lack consistent linkage criteria, making it difficult to form a complete segmented control logic.
[0003] Meanwhile, in existing evaporation and concentration systems, valves and pumps are mostly controlled independently, lacking effective linkage between actuators. For example, adjusting the steam valve opening and changing the feed pump flow rate are often executed separately, causing changes in the material state inside the evaporator to be out of sync within the same control cycle, posing challenges to the real-time performance and stability of the control system. Furthermore, the mechanisms for monitoring quantity processing and parameter updates in traditional systems are relatively simple, typically only recording the values collected in the current cycle without incorporating the actual actions of the actuators into the parameter update process. This means that operating parameters cannot reflect system dynamics in real time, hindering the judgment and execution of subsequent control steps. Summary of the Invention
[0004] In view of the above-mentioned problems, the present invention is proposed.
[0005] Therefore, the technical problem solved by this invention is that existing automated evaporation and concentration methods suffer from poor synchronization of monitoring data, fixed relationships between parameters, reliance on a single threshold for segment division, dispersed adjustments between execution structures, and a lack of sequential correlation in the control chain. The invention also addresses the problem of how to construct a system that can dynamically adjust parameter mapping relationships according to changes in operating conditions, achieve continuous connection between segment judgment and instruction generation, and ensure that the feedback from the execution action can be updated to the next cycle's operating parameter set in a timely manner.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent evaporation and concentration control method, comprising collecting evaporation monitoring data to form an operating parameter set and establishing a parameter mapping relationship.

[0018] Based on the combined judgment results of the running parameter set and mapping relationship, each segment is triggered and the segment number is calculated.
[0019] As a preferred embodiment of the intelligent evaporation and concentration control method of the present invention, the step of generating evaporation process control instructions includes taking the section number, the set of operating parameters and the parameter mapping relationship as inputs, and generating control instructions by combining the main criteria and auxiliary criteria.
[0020] The generation of control instructions includes calculating the main criteria and reconfirming the auxiliary criteria.
[0021] Once all criteria are met and the triggering conditions are met, the instruction is written into the control instruction sequence.
[0022] As a preferred embodiment of the intelligent evaporation and concentration control method of the present invention, the step of valve pump group linkage adjustment includes parsing the control command sequence and determining the corresponding execution object according to the parsed structure.
[0023] Instruction adaptation is performed on each execution object in sequence.
[0024] For valve actuators, by checking the current valve position, valve response delay, and valve stroke constraints, the transition step from the current opening to the target opening is calculated, and valve adjustment commands are generated according to the set step sequence.
[0025] For pump-type actuators, pump conditions are determined by detecting the pump's current frequency, minimum adjustable resolution, pump start-up status, and pump switching status, and pump adjustment commands are generated.
[0026] Based on the segment number in the control command sequence, the correlation of all execution objects is determined, and the steam valve, return valve, and pump group are constructed into a set of linked objects.
[0027] Based on the segment number and relevant variables in the set of operating parameters, a linkage criterion is generated from the instruction sequence to determine the linkage order and linkage conditions between the execution objects.
[0028] When the linkage conditions are met, instructions are issued to the execution objects in the linkage order.
[0029] As a preferred embodiment of the intelligent evaporation and concentration control method of the present invention, the step of updating the operating parameter set includes re-collecting the temperature, pressure, material flow rate, steam flow rate, evaporator liquid level, inlet and outlet temperature difference of the heat exchanger, reflux characteristic quantity, evaporation section temperature difference, and concentration monitoring quantities related to the material of the evaporation device.
[0030] Perform a data integrity check on the current periodic monitoring data.
[0031] By comparing the valid monitoring data recorded in the previous cycle's operating parameter set, we can determine the status of missing or abnormal values in the current cycle's monitoring data.
[0032] When missing values exist, imputation is performed on the missing points based on a time series sliding window.
[0033] When a sudden change occurs, it is removed based on the statistical deviation judgment criteria of the monitored quantity.
[0034] Another objective of this invention is to provide an intelligent evaporation and concentration control system that solves problems such as scattered monitoring parameters, unsystematic control logic, and lack of linkage in the current automated control technology for evaporation and concentration processes by constructing a collaborative working scheme for evaporation parameter acquisition and mapping, as well as segment control and linkage execution.

[0046] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0047] Example 1, referring to Figures 1-3 As an embodiment of the present invention, an intelligent evaporation and concentration control method is provided, the control method comprising:
[0048] S1: Collect evaporation monitoring data to form a set of operating parameters and establish parameter mapping relationships.
[0049] Periodically collect monitoring data from the evaporation unit.
[0050] The monitored parameters include temperature, pressure, material flow rate, steam flow rate, evaporator liquid level, inlet and outlet temperature difference of heat exchanger, secondary steam reflux parameters, and material concentration.
[0051] The monitored data are uniformly converted to the same time base, and the synchronized data sequence is established by aligning the timestamps.
[0052] During the synchronization process, monitoring quantities with missing data are interpolated, and the closest valid value is determined by a sliding window to ensure the continuity of the parameter set input.
[0053] Noise filtering is performed on the monitored quantities, and abnormal mutations are eliminated using statistical deviation judgment and normalization.
[0054] This unifies all parameters to the preset dimension range.
[0055] The processed monitoring data are combined to output a set of operating parameters.
[0056] A preferred approach for outputting the data sequence of the runtime parameter set is:
[0057] ;
[0058] in, Indicates the index of the current collection period. This indicates the temperature monitoring data over a period of time. Indicates the set of runtime parameters. Indicates pressure monitoring volume. Indicates material flow rate. Indicates steam flow rate. Indicates the liquid level in the evaporator. This indicates the temperature difference between the inlet and outlet of the heat exchanger. This represents the characteristic quantity of secondary steam reflux. This indicates the amount of material concentration monitored. This indicates the temperature monitoring data.
[0059] Furthermore, the correspondence between different monitoring quantities in the set of operating parameters is analyzed.
[0060] The analysis of the correspondence includes performing a step-by-step comparison of the temperature, pressure, flow rate, and liquid level parameters in the parameter set to form a mapping structure.
[0061] A preferred scheme for forming the mapping structure is:
[0062] ;
[0063] ;
[0064] in, Indicates the first and the Mapping value of each monitored quantity express The first in One portion, express The first in One portion, This represents a mapping structure.
[0065] The mapping structure is used to describe the relationships between variables within the evaporation system.
[0066] The process of establishing a mapping relationship includes performing correlation analysis on the parameter set, and writing the corresponding relationship into the mapping table when the correlation exceeds a pre-set mapping condition threshold.
[0067] Furthermore, the mapping structure can be used to construct a joint index of evaporation state stability to help determine the entry and maintenance conditions of the steady-state evaporation zone.
[0068] Specifically, in the current collection cycle Next, select the mapping value in the mapping structure that reflects the key coupling relationship. And calculate the changes in adjacent periods;
[0069] When in continuous If the selected mapping values all meet the judgment conditions within a collection cycle, the evaporation process is determined to be in a stable state of correlation.
[0070] If the conditions are not met, trigger the mapping update process or reduce the confidence level of the segment switching decision.
[0071] When any monitoring quantity in the operating parameter set changes beyond the limit within a continuous acquisition period, the mapping update process is triggered.
[0072] The mapping update process includes rebuilding the mapping function based on the running parameters of the current cycle.
[0073] S2: Execute multi-segment control logic based on parameter mapping relationship to generate evaporation process control instructions; perform valve and pump group linkage adjustment according to control instructions, and update the operating parameter set according to linkage adjustment.
[0074] like Figure 2 and Figure 3 As shown, the evaporation process is divided into a heating zone 100, a steady-state evaporation zone 200, a devolatilization zone 300, and a concentration endpoint zone 400.
[0075] The heating zone 100 is specifically the heater E104 area, the steady-state evaporation zone 200 is specifically the tower bottom temperature, pressure, and liquid level control area, the devolatilization zone 300 is specifically the TI103 area, used to measure the temperature and pressure monitoring of the upper part of the tower body, and the concentration zone 400 is specifically the area displaying the changes in the tower bottom liquid level.
[0076] The system checks the entry conditions for the current segment, verifies the continuous conditions within the segment, and determines the conditions for segment switching.
[0077] Based on the combined judgment results of the running parameter set and mapping relationship, each segment is triggered and the segment number is calculated.
[0078] The logic for calculating the segment number is as follows: first, the entry conditions of the segment are checked, then the continuous conditions within the segment are verified, and the segment migration is completed when the switching conditions are met.
[0079] Specifically: the temperature threshold is used to determine the completion status of the heating process; the liquid level difference or liquid level change amplitude threshold is used to determine whether the evaporation process has entered a state of stable liquid level change; and the material concentration threshold is used to determine whether the process has entered the relevant state of the concentration endpoint; based on the above determinations, the segment number is output.
[0080] A preferred scheme for calculating the segment number is:
[0081] ;
[0082] ;
[0083] in, This indicates the difference between the liquid level in the current cycle and the liquid level in the previous cycle. This indicates the liquid level for the current cycle. Indicates the liquid level in the previous cycle. The temperature threshold indicating when heating is complete. The threshold indicating when the liquid level change tends to a steady state. Indicates the material concentration threshold. Indicates the section number, This indicates the amount of material concentration monitored.
[0084] Specifically, in the heating zone, it is determined whether the temperature rise meets the conditions for entering the steady-state evaporation zone, and in the devolatilization zone, it is determined whether the change rate of light components meets the conditions for zone transition.
[0085] The section number, operating parameter set, and parameter mapping relationship are used as inputs to generate control commands through a combination of primary and auxiliary criteria.
[0086] Among them, the main criterion is used to determine the main adjustment direction and adjustment amount of the control command, and it is preferably the deviation criterion of the key controlled variable corresponding to the segment;
[0087] When the section is a heating zone or a steady-state evaporation zone, the key controlled variable is preferably the temperature monitoring quantity, and the main criterion can be the deviation between the target temperature and the current temperature.
[0088] When the control of the section is dominated by liquid level, the key controlled variable is preferably the evaporator liquid level, and the main criterion can be the deviation between the target liquid level and the current liquid level.
[0089] Auxiliary criteria are used to perform secondary confirmation and constraint on the control commands output by the main criteria, including: safety range constraints of pressure monitoring quantities, rate of change constraints of liquid level, correlation stability constraints derived from parameter mapping relationships, and actuator constraints.
[0090] The preferred combination of primary and secondary criteria is as follows: first, the target adjustment amount or target value is calculated by the primary criterion; then, the secondary criteria are checked one by one. When any secondary criterion is not met, the target adjustment amount is subjected to limiting, holding or downgrading update processing, and the processing result is written into the control command sequence.
[0091] A preferred method for generating control commands is:
[0092] ;
[0093] in, This indicates the target opening degree of the steam valve in the current cycle. This indicates the target opening degree of the steam valve in the previous cycle. This indicates the regulating coefficient of the steam valve. Indicates a section The corresponding target temperature, This indicates the temperature monitoring data collected previously.
[0094] The generation of control instructions includes calculating the main criteria and reconfirming the auxiliary criteria.
[0095] Once all criteria are met and the triggering conditions are met, the instruction is written into the control instruction sequence.
[0096] Furthermore, the control instruction sequence is parsed, and the corresponding execution object is determined based on the parsed structure.
[0097] Instruction adaptation is performed on each execution object in sequence.
[0098] For valve actuators, by checking the current valve position, valve response delay, and valve stroke constraints, the transition step from the current opening to the target opening is calculated, and valve adjustment commands are generated according to the set step sequence.
[0099] For pump-type actuators, pump conditions are determined by detecting the pump's current frequency, minimum adjustable resolution, pump start-up status, and pump switching status, and pump adjustment commands are generated.
[0100] A preferred method for generating pump control commands is as follows:
[0101] ;
[0102] in, Indicates the target frequency of the pump in the current cycle. This indicates the target frequency of the pump in the previous cycle. Indicates the pump adjustment coefficient. Indicates a section The corresponding target liquid level, This indicates the liquid level for the current cycle.
[0103] Based on the segment number in the control command sequence, the correlation of all execution objects is determined, and the steam valve, return valve, and pump group are constructed into a set of linked objects.
[0104] Based on the segment number and relevant variables in the set of operating parameters, a linkage criterion is generated from the instruction sequence to determine the linkage order and linkage conditions between the execution objects.
[0105] The linkage criteria include: segment number, key variable deviation, key variable change rate, and stability index of parameter mapping relationship.
[0106] The preferred criterion for determining the linkage condition is: when the change in the target value of the main control object exceeds the preset linkage trigger threshold and pressure is applied, linkage is allowed to be triggered;
[0107] When the mapping stability index is not met or the rate of change exceeds the limit, segment-related interactions are prohibited and the instruction is executed with hold processing.
[0108] The rule for determining the linkage sequence is preferably related to the section number: steam valve adjustment instructions are issued first in the heating zone, and after the valve reaches the target opening degree or reaches the preset transition step length node, the return valve and pump group adjustment instructions are issued.
[0109] In the steady-state evaporation zone, the fine-tuning valve is maintained under temperature constraints first, and then the pump frequency is adjusted according to the liquid level deviation.
[0110] In the devolatilization zone and concentration endpoint zone, pressure and concentration-related constraints are prioritized, and then linkage updates related to reflux are performed.
[0111] When the linkage conditions are met, instructions are issued to the execution objects in the linkage order.
[0112] Furthermore, the temperature, pressure, material flow rate, steam flow rate, evaporator liquid level, inlet and outlet temperature difference of the heat exchanger, reflux characteristic quantity, evaporation section temperature difference, and concentration monitoring quantities related to the material of the evaporation device were re-collected.
[0113] Perform a data integrity check on the current periodic monitoring data.
[0114] By comparing the valid monitoring data recorded in the previous cycle's operating parameter set, we can determine the status of missing or abnormal values in the current cycle's monitoring data.
[0115] Specifically, when missing values exist, the missing points are imputed based on a time series sliding window; when abrupt values exist, they are removed based on the statistical deviation judgment conditions of the monitored quantities.
[0116] A preferred approach for eliminating statistical bias judgment criteria is as follows:
[0117] The median of the central statistic and the absolute median difference of the discrete statistic are taken. If the absolute value of the difference between the collected value and the median is less than the median difference, the value is discarded.
[0118] Example 2 is an embodiment of the present invention, which provides an intelligent evaporation and concentration control system, including an evaporation parameter acquisition and mapping construction module and a section control and linkage execution module.
[0119] The evaporation parameter acquisition and mapping module is used to collect evaporation monitoring data to form a set of operating parameters and establish parameter mapping relationships.
[0120] The section control and linkage execution module is used to execute multi-section control logic according to parameter mapping relationship, generate evaporation process control instructions; perform valve and pump group linkage adjustment according to control instructions, and update the operating parameter set according to linkage adjustment.
