DETAILED DESCRIPTION

[0011] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, systems, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0012] First of all, the production equipment in this application are all equipment used in the alkali process production process, such as evaporation tank, evaporation tank liquid level regulating valve, condensate tank, condensate tank liquid level regulating valve, alkali flow regulating valve, etc. The alkali process production process refers to the process of converting 32% alkali into 50% alkali through process reaction. During the entire production process, the liquid level in the evaporation tank can be measured with a liquid level gauge, and the temperature in the evaporation tank can be measured with a thermometer. The regulating valve (valve) can be centrally controlled by electronic equipment. Each regulating valve also has a single-loop PID automatic adjustment function. When the main control part of the electronic equipment fails, the single-loop PID automatic adjustment function corresponding to each regulating valve can still achieve automatic control.

[0013] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.

[0014] Please refer to Figure 1 , Figure 1 A flowchart of a method for controlling production equipment provided in one embodiment of the present application can be executed by an electronic device. The method may include S101 to S104.

[0015] S101: Obtain target production requirements, which include target weight and production time of product alkali.

[0016] In this embodiment, the target production demand is a specific production task indicator to be achieved based on the production plan or process requirements. It serves as the guiding and control goal for the entire production process. In this embodiment, the target production demand includes the target weight and production duration of the product alkali. The product alkali refers to the target product produced through the alkali process, namely, an alkali solution with a concentration increased from 32% to 50%. Compared to the raw alkali (32% alkali), the product alkali has a higher concentration. The target weight is the desired weight of the product alkali output (usually in tons, kilograms, etc.), pre-set according to the production plan. The target duration is the time period required to produce the target weight of the product alkali (usually in hours, minutes, etc.).

[0017] This embodiment provides quantifiable control targets for subsequent production processes by clarifying the target weight and production time of the product alkali, ensuring that electronic equipment can dynamically adjust the operating parameters of production equipment based on real-time data to achieve efficient and accurate process control.

[0018] S102: Based on the target production demand, obtain the regional production items of each production area, wherein there are multiple production areas, and the production areas are divided according to the alkali process production flow. Each production area includes at least one type of production equipment. The regional production items are used to represent the weight and production time of the product alkali required to be produced in each production area under the conditions of production time and the target weight of the product alkali required to be produced.

[0019] In this embodiment, there are multiple production areas, which are physical units divided according to the alkali process production flow, such as a three-effect evaporation area, a two-effect evaporation area, and a single-effect evaporation area. Each production area includes at least one type of production equipment. For example, a three-effect evaporation area includes different types of production equipment, such as evaporation tanks, heaters, and control valves.

[0020] In this example, the regional production item is the weight of caustic soda produced that each production area is required to produce within a given production duration and target weight. For example, if the overall target in the target production requirement is "100 kg of 50% caustic soda in 8 hours," the 3-effect evaporation area might need to produce "120 kg of 38% caustic soda in 2 hours," the 2-effect evaporation area might need to produce "110 kg of 45% caustic soda in 2 hours," and the 1-effect evaporation area might need to produce "100 kg of 50% caustic soda in 4 hours."

[0021] S103: Determine an adjustment mode of each production area based on the regional production item of the production area, where the adjustment mode includes the start / stop state and the opening degree of each valve.

[0022] In this embodiment, the regulation method is a strategy for setting and controlling the operating status of valve-type equipment within a production area to achieve regional production targets. The regulation method includes the start / stop status and valve opening of each valve. The valve start / stop status, or the valve's on / off state, controls the flow of fluids. Valve opening refers to the degree to which the valve is open, typically expressed as a percentage, such as 0% to 100%, and is used to control parameters such as fluid flow and pressure. For example, the evaporator liquid level control valve can control the amount of alkaline solution flowing into the evaporator by adjusting the valve opening to maintain a stable liquid level within the tank.

[0023] Each production area has different regional production items, and the corresponding adjustment method is also different. For example, the regional production item of the three-effect evaporation area may be "produce 120kg of 38% alkali in 2 hours". Then the adjustment method of the three-effect evaporation area can be to open the raw alkali liquid pump, open the raw alkali liquid regulating valve, and keep the valve opening at 10%. After the 32% alkali treatment is completed, open the three-effect alkali regulating valve and keep the opening at 10%; the adjustment method of the two-effect evaporation area can be to open the second-effect alkali pump, open the second-effect alkali regulating valve, and keep the valve opening at 12%; the adjustment method of the one-effect evaporation area can be to open the first-effect alkali pump, open the first-effect alkali pump regulating valve, and keep the valve opening at 10%.

[0024] Because the entire alkali process production process is to convert 32% alkali into 50% alkali through process reaction, 50% alkali can be obtained after 32% alkali passes through the 3rd effect evaporation area, the 2nd effect evaporation area and the 1st effect evaporation area in sequence.

[0025] S104: Adjust the production equipment in each production area based on the adjustment method of the production area.

[0026] In this example, production equipment refers to equipment involved in alkali process production, including but not limited to valves (such as liquid level control valves, flow control valves, and pressure control valves), containers (such as evaporation tanks, condensate tanks, and alkali liquid storage tanks), detection equipment (such as liquid level gauges and thermometers), and actuators (such as pumps). The control methods for each production area can be used to adjust the control valves, pumps, and other equipment in that area.

[0027] From the above, it can be concluded that the embodiment of the present application determines the regional production items of each production area based on the target production demand, and then determines the adjustment method based on the regional production items, so that the start and stop status and opening adjustment of each valve can closely revolve around the production target, and realizes the correlation and coordination between the control parameters of each valve. When the production demand changes, the control parameters of each valve can be adjusted in a timely and accurate manner, ensuring the stability and efficiency of the entire production process and improving the production efficiency of alkali products.

[0028] In addition, the embodiment of the present application obtains the target weight and production time of the product alkali, and determines the regional production items of each production area based on this, so that the production process can be accurately planned and controlled. Each production area clearly defines the weight of the product alkali required to be produced under given conditions, so that production resources can be reasonably allocated and each production link is closely connected, avoiding resource waste and production disconnection in the production process, not only improving production efficiency, but also better ensuring the quality consistency of the product alkali.

[0029] In one embodiment of the present application, the multiple production areas include a first production area, a second production area, and a third production area, and the pipelines in the first production area, the second production area, and the third production area are connected in sequence; In the embodiment of the present application, determining the adjustment mode of each production area based on the regional production item of the production area includes: determining a first adjustment method for the first production area based on the regional production item corresponding to the first production area; Determining an initial adjustment mode for a second production area based on a first adjustment mode for the first production area, and adjusting the initial adjustment mode for the second production area based on a regional production item corresponding to the second production area to obtain a second adjustment mode; Based on the first adjustment method of the first production area, the initial adjustment method of the third production area is determined; based on the regional production item corresponding to the second production area, the initial adjustment method of the third production area is adjusted to obtain the target adjustment method; based on the regional production item corresponding to the third production area, the target adjustment method is adjusted to obtain the third adjustment method.

[0030] In this embodiment, the multiple production areas include a first production area, a second production area, and a third production area. The first production area may be a three-effect evaporation area, the second production area may be a two-effect evaporation area, and the third production area may be a single-effect evaporation area. Because the three production areas are divided according to the alkali process production flow, the three production areas are connected by pipelines.

[0031] In this embodiment, the first, second, and third adjustment modes all include the open / closed state of the control valve, the opening degree of the control valve, etc. However, the three adjustment modes also differ in that they are determined based on different criteria and are targeted at different production equipment.

[0032] For example, the first adjustment method is determined based on the regional production items corresponding to the first production area. The equipment targeted by this adjustment method may include the 32% raw alkali solution regulating valve, the triple-effect alkali solution regulating valve, and the triple-effect condensate tank level regulating valve. Furthermore, the first adjustment method may also include adjustments to the level gauge parameters, thermometer, hygrometer, and other equipment parameters corresponding to the triple-effect evaporator.

[0033] The second adjustment method is determined based on the first adjustment method of the first production area and the regional production parameters corresponding to the second production area. The adjustment method of the upstream area (the first production area) will affect the initial adjustment method of the downstream area. The final adjustment method of each area needs to be modified based on its own production parameters. The second adjustment method targets production equipment such as the second-effect alkali solution regulating valve and the second-effect condensate tank level regulating valve. In addition, the second adjustment method can also include adjustments to the parameters of the liquid level gauge corresponding to the second-effect evaporator, as well as the parameters of the thermometer, hygrometer, and other equipment.

[0034] The third adjustment method works similarly, as the adjustment methods of the upstream areas (the first and second production areas) affect the production methods of the downstream areas. Therefore, the third adjustment method is determined based on the first adjustment method, the regional production parameters of the second and third production areas, and the regional production parameters of the third production area. The third adjustment method targets production equipment such as the first-effect alkali solution regulating valve and the first-effect condensate tank level regulating valve. Furthermore, the third adjustment method can also include adjusting the parameters of the level gauge corresponding to the first-effect evaporator, as well as the parameters of the thermometer, hygrometer, and other equipment.

[0035] As can be seen from the above, first, the embodiment of the present application establishes a regulation linkage mechanism between production areas. Using the regulation parameters of the first production area as a benchmark, it provides an initial regulation method for the second and third production areas, avoiding parameter conflicts caused by independent regulation of each area. This ensures that key indicators such as temperature and flow rate maintain consistency during cross-area transmission, thereby improving the overall stability of the system.

[0036] Secondly, based on the initial adjustment method, the downstream area in the embodiment of the present application made secondary adjustments in combination with the actual production items of each area, realizing the dual control mode of "reference framework + personalized calibration", which not only ensures the standardization of the production process, but also can flexibly respond to the special process flows of different areas, further improving the consistency of production efficiency and product quality.

[0037] In one embodiment of the present application, determining a first adjustment mode for the first production area based on the regional production item corresponding to the first production area includes: determining a first target liquid level value of a first evaporation tank based on a weight of alkali product required to be produced in the first production area, and comparing a real-time liquid level value of the first evaporation tank with the first target liquid level value, wherein the first evaporation tank belongs to the first production area; If the real-time liquid level value of the first evaporation tank is greater than the first target liquid level value, reducing the opening of the flow control valve and the liquid level control valve in the first production area; If the real-time liquid level value of the first evaporation tank is less than or equal to the first target liquid level value, the openings of the flow regulating valve and the liquid level regulating valve in the first production area are increased.

[0038] In this embodiment, the core equipment in the first production area is the first evaporator (i.e., the three-effect evaporator). The liquid level in the first evaporator directly reflects the amount of alkaline solution stored in the tank. The production time required for each production area to produce the product alkali has no impact on the regulation method for that production area. With a fixed production time, maintaining the liquid level in the first evaporator at the target value means that the amount of alkaline solution flowing in and out per unit time meets the weight requirement for the area's production item. Therefore, when the liquid level in the first evaporator changes, the state of the regulating valve must be adjusted promptly.

[0039] In this embodiment, the first target liquid level is a theoretical value calculated based on the weight of the alkali product required to be produced in the first production area, the volume of the first evaporator, and the production duration. When the real-time liquid level of the first evaporator is greater than the first target liquid level, it indicates that the current inflow exceeds the outflow, and the alkali solution inventory in the tank exceeds expectations, which may lead to overload or low production efficiency in subsequent production areas (the second and third production areas). In this case, the flow control valve opening can be reduced to reduce the input flow rate of the alkali solution (e.g., the input of raw alkali solution); the level control valve opening can be reduced to reduce the output flow rate of the alkali solution (e.g., the amount of alkali solution delivered to the second production area). When the real-time liquid level of the first evaporator is less than or equal to the first target liquid level, it indicates that the current inflow is less than the outflow, and the alkali solution inventory in the tank is insufficient, which may lead to subsequent production interruption or inability to complete the regional production item. In this case, the flow control valve opening can be increased to increase the input flow rate of the alkali solution (e.g., increasing the supply of raw alkali solution); and the level control valve opening can be increased to increase the output flow rate of the alkali solution.

[0040] In this embodiment, if the real-time liquid level value of the first evaporator tank is greater than the first target liquid level value, the accuracy of the liquid level gauge parameters corresponding to the first evaporator tank, as well as the accuracy of the thermometer parameters and the hygrometer parameters, may be improved. If the real-time liquid level value of the first evaporator tank is less than or equal to the first target liquid level value, the accuracy of the liquid level gauge parameters corresponding to the first evaporator tank, as well as the accuracy of the thermometer parameters and the hygrometer parameters, may be reduced.

[0041] From the above, it can be concluded that the embodiment of the present application converts the abstract "product alkali weight index" into a specific "liquid level control target" through a closed-loop mechanism of liquid level feedback-valve adjustment, and uses dynamic adjustment of the valve opening to achieve precise matching of production flow, ensuring that each production area completes the weight task within the specified time, while maintaining the stability and continuity of the entire alkali process production process.

[0042] In one embodiment of the present application, determining an initial adjustment mode of a second production area based on a first adjustment mode of a first production area includes: If the first adjustment mode is to reduce the opening of the flow control valve and the liquid level control valve in the first production area, then the initial adjustment mode of the second production area is determined to be to increase the opening of the flow control valve and the liquid level control valve in the second production area; If the first adjustment mode is to increase the opening of the flow control valve and the liquid level control valve in the first production area, then determining the initial adjustment mode of the second production area is to reduce the opening of the flow control valve and the liquid level control valve in the second production area; The second adjustment method is obtained by adjusting the initial adjustment method of the second production area based on the regional production item corresponding to the second production area, including: A second target liquid level value of the second evaporation tank is determined based on the weight of the alkali product required to be produced in the second production area. Based on a comparison result of the real-time liquid level value of the second evaporation tank and the second target liquid level value, the initial regulation mode of the second production area is adjusted to obtain a second regulation mode.

[0043] In the alkali process of this example, 32% alkali must pass through the first, second, and third production areas in sequence to produce 50% alkali. The output of the first production area directly affects the input of the second production area, so the regulation of the two production areas must be linked to maintain material balance throughout the process.

[0044] In this embodiment, when the regulating valve opening in the first production zone is reduced (i.e., the flow / liquid level regulating valve opening is reduced), its output flow rate decreases, resulting in a decrease in the input to the second production zone. To prevent the liquid level in the evaporator tank in the second production zone from dropping, the regulating valve opening in that zone needs to be increased to replenish the flow rate and maintain a stable liquid level. Conversely, if the regulating valve opening in the first production zone is increased, the output flow rate increases, and the input to the second zone increases. In this case, the regulating valve opening in that zone needs to be reduced to prevent overflow or overpressure due to excessively high liquid levels.

[0045] The "reverse compensation" logic of the initial adjustment method in this embodiment is essentially to achieve dynamic balance of material flow through reverse matching of the adjustment actions in the upstream and downstream areas, so as to avoid liquid level fluctuations or material accumulation in the downstream due to upstream adjustment, thereby affecting production efficiency.

[0046] In this embodiment, after the initial control mode is determined, it needs to be revised based on the regional production parameters for the specific area. The regional production parameters for the second production area determine the second target liquid level for its evaporator. This value is the theoretically optimal liquid level calculated based on the production volume and is used to guide the precise control of the regulating valve opening. If the real-time liquid level of the second evaporator deviates from the target liquid level, further adjustments are required based on the initial control mode. Specifically, if the real-time liquid level is less than the target liquid level (e.g., due to reduced upstream flow), even if the initial control mode is "increase opening," the opening needs to be further increased based on the deviation to accelerate material input. If the real-time liquid level is greater than or equal to the target liquid level (e.g., due to excessive upstream flow), the opening needs to be further reduced or the valve needs to be temporarily closed, in addition to the initial "decrease opening" mode, to prevent the liquid level from exceeding the limit.

[0047] In this embodiment, if the first regulation mode is to maintain the openings of the flow control valve and the liquid level control valve in the first production area and increase the evaporation temperature in the first evaporator, the initial regulation mode for the second production area is determined to be to increase the openings of the flow control valve and the liquid level control valve in the second production area or to decrease the evaporation temperature in the second evaporator.

[0048] If the first adjustment method is to maintain the openings of the flow control valve and the liquid level control valve in the first production area and reduce the evaporation temperature in the first evaporator, the initial adjustment method for the second production area is determined to be to reduce the openings of the flow control valve and the liquid level control valve in the second production area or to increase the evaporation temperature in the second evaporator.

[0049] From the above, we can conclude that, first, this embodiment achieves dynamic material balance through the reverse linkage of upstream and downstream production area adjustment methods, avoiding liquid level fluctuations or material accumulation downstream due to upstream production area adjustments, thereby ensuring the continuity of the production process. Second, this embodiment sets target liquid level values ​​based on regional production items and adjusts the initial adjustment method based on real-time liquid level value feedback, ensuring that each production area can independently complete its production tasks, ultimately achieving improved production efficiency.

[0050] In one embodiment of the present disclosure, an initial adjustment method of the third production area is determined based on the first adjustment method of the first production area, the initial adjustment method of the third production area is adjusted based on the regional production item corresponding to the second production area to obtain a target adjustment method, and the target adjustment method is adjusted based on the regional production item corresponding to the third production area to obtain a third adjustment method.

[0051] In this embodiment, if the first adjustment method is to reduce the opening of the flow control valve and the liquid level control valve in the first production area, then the initial adjustment method of the third production area is determined to be to increase the opening of the flow control valve and the liquid level control valve in the third production area at a first ratio.

[0052] A second target liquid level value for the second evaporator is determined based on the weight of the alkali product required to be produced in the second production area. Based on a comparison of the real-time liquid level value of the second evaporator and the second target liquid level value, the initial control mode for the third production area is adjusted to obtain a target control mode. If the real-time liquid level value of the second evaporator is greater than the second target liquid level value, the openings of the flow control valve and the liquid level control valve in the third production area are reduced by a second ratio. If the real-time liquid level value of the second evaporator is less than or equal to the second target liquid level value, the openings of the flow control valve and the liquid level control valve in the third production area are increased by a second ratio.

[0053] A third target liquid level value for the third evaporator is determined based on the weight of the alkali product required to be produced in the third production area. The target regulation mode for the third production area is adjusted based on a comparison between the real-time liquid level value of the third evaporator and the third target liquid level value to obtain a third regulation mode. If the real-time liquid level value of the third evaporator is greater than the third target liquid level value, the openings of the flow control valve and the liquid level control valve in the third production area are reduced by a third ratio. If the real-time liquid level value of the third evaporator is less than or equal to the third target liquid level value, the openings of the flow control valve and the liquid level control valve in the third production area are increased by a third ratio. In summary, the third regulation mode involves multiplying the first ratio, the second ratio, and the third ratio to obtain the adjustment of the openings of the flow control valve and the liquid level control valve in the third regulation mode.

[0054] In one embodiment of the present application, based on the target production demand, obtaining regional production items of each production area includes: Establish a mathematical model of the production process, using the production capacity parameters and basic material conversion rates of each production area as model parameters; The target production demand, the actual material conversion rate of each production area, and the equipment operating parameters of each production area are input into the production process mathematical model to obtain the regional production items of each production area.

[0055] In this embodiment, the production process mathematical model is a mixed integer non-linear programming (MINLP) model, which is a mathematical expression or system of equations used to describe the relationships between material conversion and capacity allocation in the alkali process production process. Parameters of the MINLP model include the capacity parameter for each production area and the basic material conversion rate.

[0056] Capacity parameters represent indicators related to the amount of material or output that each production area can process per unit time. Basic material conversion rate represents the ratio of raw alkali (e.g., 32% alkali) converted to the target product (product alkali or intermediate) under ideal or standard conditions. Actual material conversion rate represents the actual ratio of raw alkali converted to product alkali (or intermediate) during the actual production process in each production area. Equipment operating parameters represent the operating status of production equipment (e.g., regulating valves, evaporation tanks) within each production area.

[0057] In this embodiment, the target production demand, the actual material conversion rate of each production area, and the equipment operating parameters of each production area are input into the production process mathematical model to obtain the regional production items of each production area, including: For each production area, the weight of the caustic soda product in that production area is calculated using the first formula based on the target production demand, the actual material conversion rate of that production area, and the equipment operating parameters of that production area. The production duration of that production area is calculated based on the weight of the caustic soda product in that production area and the maximum production capacity per unit time of that production area. The weight of the caustic soda product in that production area and the production duration of that production area are combined as the regional production item for that production area. Among them, the first formula is:

[0058] Among them, Q i represents the weight of the product alkali in the i-th production area, D represents the target weight of the product alkali, t represents the production time, C i represents the maximum production capacity per unit time of the i-th production area, represents the basic material conversion rate of the k-th production area, Represents the equipment operating parameter vector of the kth production area P k Correction function for basic material conversion rate, P k represents the equipment operation parameter vector of the kth production area, and n represents the total number of production areas.

[0059] In this embodiment, ,in, t k 、 P k are temperature parameters and pressure parameters, is the calibration factor. , Represents the actual material conversion rate of the kth production area.

[0060] As can be seen from the above, this example provides a specific method for calculating regional production items for each production area using the MINLP model. Based on the basic conversion rate and equipment parameter correction function, this method can optimize production by combining theoretical and practical conditions. Furthermore, by balancing capacity constraints with target demand, it can avoid capacity waste or overload, achieve efficient utilization of production resources, and effectively improve the scientific nature and execution efficiency of production plans.

[0061] In one embodiment of the present application, a production process mathematical model is established, which then includes: Dynamically correct capacity parameters based on equipment aging factors, which are derived from the operating time and cumulative processing data volume of production equipment in each production area; Based on the revised production capacity parameters, a revised production process mathematical model is determined; The target production demand, the actual material conversion rate of each production area, and the equipment operating parameters of each production area are input into the production process mathematical model to obtain the regional production items of each production area, including: The target production demand, the actual material conversion rate of each production area, and the equipment operating parameters of each production area are input into the revised production process mathematical model to obtain the regional production items of each production area.

[0062] In this embodiment, the equipment aging factor is a coefficient that quantifies the performance degradation of production equipment due to accumulated operating time and increased processing load. It can dynamically adjust production capacity parameters to reflect the actual decline in equipment production capacity over time. The equipment aging factor is derived based on the operating time and the accumulated processing data volume of production equipment in each production area, for example, using the following formula:

[0063] in, represents the equipment aging factor of the jth production equipment, a and is the decay rate parameter, t j is the coefficient corresponding to the cumulative operating time of the j-th production equipment, V j Indicates the cumulative amount of data processed by the j-th production equipment.

[0064] In this embodiment, the capacity parameters are dynamically modified based on the equipment aging factor, including: The revised capacity parameters are: ,in, It represents the maximum production capacity per unit time of the i-th production area after correction, , represents the number of production equipment in the i-th production area, represents the overall equipment aging factor for the i-th production area. When the production capacity parameter changes, the maximum production capacity per unit time of the i-th production area in the production process mathematical model becomes the maximum production capacity per unit time of the i-th production area after correction. Calculating the weight of the alkali product in the corresponding production area based on this parameter is more accurate. In this embodiment, the corrected production process mathematical model can be expressed using the corrected first formula, namely:
