[0031] Step S15, controlling the polymerization drying system based on the target operating parameters to perform polymerization drying on the object to be dried.

[0032] A polymerization drying control method of the present embodiment uses the drying tower parameter set of the polymerization drying system to train the initial time series model to obtain a target drying model. The real-time operating parameters of the polymerization drying system and the attribute parameters of the object to be dried are obtained, input into the target drying model for processing, and the target operating parameters are obtained. The polymerization drying system is controlled based on the target operating parameters to perform polymerization drying on the object to be dried. In this way, the operating parameters of the polymerization drying system are automatically adjusted using the trained target drying model to achieve dynamic regulation of various drying variables of the polymerization drying system, reduce coupling effects, and make control less difficult. At the same time, this automated control method reduces the complexity of the drying process and improves the drying efficiency of the system.

[0033] Among them, the real-time operation parameters include real-time bed temperature, real-time airflow pipe hot air temperature, real-time airflow pipe hot air temperature and real-time steam pressure. The attribute parameters include the type of drying object, the weight of the drying object, the bed temperature setting value, and the airflow pipe bottom setting temperature (the bed temperature setting value and the airflow pipe bottom setting temperature corresponding to different objects to be dried are different to avoid damaging the physical properties of the objects to be dried).

[0034] In this embodiment, the working principle of the polymerization drying system is: mainly using high temperature and high-speed airflow to quickly dry the wet raw material to be dried (such as polyvinyl chloride PVC) to meet the processing requirements. The specific process is as follows:

[0035] Heating and conveying of hot air: First, the hot air is heated by the heater and then sent to the drying tower through the fan. The wet raw materials enter the drying tower after pre-treatment such as crushing and mixing.

[0036] Drying process: In the drying tower, high-temperature, high-speed air fully contacts the raw materials and quickly removes the moisture in the raw materials. At the same time, according to different needs, an appropriate amount of air carrier, such as starch, calcium carbonate, etc., can be added to help absorb moisture and improve drying efficiency.

[0037] Treatment after drying: The dried PVC raw materials will be discharged from the drying tower together with the carrier gas and enter the next process.

[0038] The process characteristics of the polymerization drying system are reflected in:

[0039] High efficiency and fast speed: high temperature and high speed airflow are used for drying, which has high heat and mass transfer efficiency and fast drying speed, thus improving production efficiency.

[0040] Simple operation: The equipment has a simple structure and is easy to operate, which can reduce labor costs and maintenance costs1.

[0041] Wide applicability: It is suitable for raw materials in various forms, such as granular, powdery, etc., and has a wide range of humidity requirements for raw materials, which can meet different production needs.

[0042] Energy saving and environmental protection: Through reasonable design and control, low energy consumption and low emissions can be achieved, which meets the requirements of energy saving and environmental protection in modern industry.

[0043] The application scenario of the polymerization drying system is mainly in the plastic processing industry, especially when processing plastic raw materials such as polyvinyl chloride (PVC). This drying method can effectively improve production efficiency and product quality, reduce energy consumption and pollution emissions, and is an important direction for the green development of the plastic processing industry.

[0044] Strong adjustability: process parameters such as temperature and speed can be adjusted according to actual needs to adapt to different drying requirements.

[0045] Optionally, a drying tower parameter set of a polymerization drying system is obtained, including:

[0046] Obtaining original drying tower parameters of the polymerization drying system in a historical period, the original drying tower parameters including original property parameters and original operation parameters;

[0047] Preprocessing the original drying tower parameters to obtain historical drying tower parameters, which include drying object attribute parameters and historical operation parameters;

[0048] Using the dry object attribute parameters as labels of the corresponding historical operating parameters to obtain the labeled operating parameters;

[0049] Arrange multiple labeled operating parameters in chronological order to form a drying tower parameter set.

[0050] In this embodiment, the original drying tower parameters of the polymerization drying system in the historical time period are obtained, and the original drying tower parameters are preprocessed to reduce useless data in the original drying tower parameters, so as to obtain historical drying tower parameters with fewer interference parameters. The drying object attribute parameters are used as labels of the corresponding historical operating parameters to obtain labeled operating parameters, and multiple labeled operating parameters are arranged in chronological order to form a drying tower parameter set, which can improve the accuracy of the training set, thereby improving the model accuracy of the target drying model obtained by subsequent model training, and further improving the accuracy of the subsequent use of the target drying model to dynamically control the operating parameters of the polymerization drying system.

[0051] The preprocessing in this embodiment includes data cleaning and screening.

[0052] Optionally, the initial time series model is trained using the drying tower parameter set to obtain a target drying model, including:

[0053] The drying tower parameter set is input into the initial time series model for processing to obtain the predicted operating parameters;

[0054] Obtaining error loss based on the predicted operating parameters and the corresponding true target operating parameters;

[0055] The initial time series model is optimized based on the error loss to obtain the target drying model.

[0056] In this embodiment, the drying tower parameter set is input into the initial time series model for processing to obtain the predicted operating parameters. Based on the error loss obtained from the predicted operating parameters and the corresponding true target operating parameters, the difference between the predicted value and the true value can be understood, so that it can be understood whether the model accuracy of the initial time series model meets the requirements. The initial time series model is optimized based on the error loss so that the model accuracy of the optimized target drying model can meet the requirements, so that the accuracy of the subsequent dynamic regulation of the operating parameters of the polymerization drying system using the target drying model can meet the requirements.

[0057] Optionally, the initial time series model is optimized based on the error loss to obtain a target drying model, including:

[0058] When the error loss meets the preset requirements, the initial time series model is used as the target drying model;

[0059] When the error loss does not meet the preset requirements, the network parameters of the initial time series model are adjusted to obtain an optimized time series model;

[0060] The optimized time series model is trained using the drying tower parameter set. When the corresponding error loss meets the preset requirements, the optimized time series model corresponding to the error loss meeting the preset requirements is used as the target drying model.

[0061] In this embodiment, when the error loss meets the preset requirements, it means that the model accuracy of the corresponding initial time series model can meet the requirements, and the initial time series model at this time can be used as the target drying model. When the error loss does not meet the preset requirements, it means that the model accuracy of the corresponding initial time series model does not meet the requirements. At this time, it is necessary to optimize the initial time series model by adjusting the network parameters of the initial time series model, so that the error loss corresponding to the optimized time series model obtained by optimization meets the preset requirements, that is, the model accuracy of the optimized time series model obtained by optimization meets the requirements, and the optimized time series model at this time is used as the target drying model. In this way, the model accuracy of the target drying model obtained meets the requirements, so that the accuracy of the subsequent use of the target drying model to dynamically control the operating parameters of the polymerization drying system can meet the requirements.

[0062] The preset requirement is that the multiple error losses corresponding to the drying tower parameter set are all less than or equal to the preset value. The network parameters of the initial time series model include hidden layer weights and output layer weights.

[0063] Optionally, the attribute parameters and the real-time operation parameters are input into the target drying model for processing to obtain the target operation parameters, including:

[0064] In the target drying model, the target time step corresponding to the real-time operating parameters is determined;

[0065] The real-time operation parameters are input into the target time step, and the real-time operation parameters are processed using the hidden layer and output layer corresponding to the target time step to obtain the target operation parameters.

[0066] In this embodiment, the real-time operation parameter includes the real-time time of the object to be dried in the polymerization drying system. Based on the real-time time in the real-time operation parameter, the corresponding target time step in the target drying model can be found, and the real-time operation parameter is input into the target time step, and the real-time operation parameter is processed using the hidden layer and output layer corresponding to the target time step to obtain the target operation parameter, so that the model can directly obtain the current desired target operation parameter based on the real-time operation parameter, so as to control the polymerization drying system based on the target operation parameter, realize dynamic drying of the object to be dried, and improve the flexibility of drying.

[0067] In this embodiment, the hidden layer and output layer corresponding to the target time step include the hidden layer and output layer of the target time step itself, and the hidden layer and output layer of the time step after the target time step.

[0068] Optionally, controlling the polymerization drying system to perform polymerization drying on the object to be dried according to the target operating parameters includes:

[0069] Determine the optimized control parameters based on the real-time operating parameters and the target operating parameters;

[0070] The polymerization drying system is controlled according to the optimized control parameters to perform polymerization drying treatment on the object to be dried.

[0071] In this embodiment, the optimized control parameters are determined based on the real-time operating parameters and the target operating parameters, and the polymerization drying system is controlled according to the optimized control parameters to perform polymerization drying treatment on the object to be dried, so that the polymerization drying system can dynamically dry the object to be dried, thereby enabling targeted drying and improving the drying efficiency of the system.

[0072] In this embodiment, the target operating parameters include target bed temperature, target airflow pipe bottom temperature, target airflow pipe hot air temperature and target steam pressure. The optimized control parameters include target hot air temperature and target air temperature regulating valve opening, and the target hot air temperature is used to adjust the bed temperature, the airflow pipe bottom temperature and the airflow pipe hot air temperature. The target air temperature regulating valve opening is adjusted based on the real-time bed temperature, the real-time airflow pipe bottom temperature, the real-time airflow pipe hot air temperature and the real-time steam pressure to control the drying temperature and system temperature and improve the stability and safety of the drying system. When the polymerization drying system is controlled according to the optimized control parameters, the real-time bed temperature must always be less than or equal to the bed temperature setting value, the real-time airflow pipe bottom temperature must always be less than or equal to the airflow pipe bottom setting temperature, the real-time steam pressure must be within a pressure range, and the pressure disturbance corresponding to the real-time steam pressure per unit time is only greater than a maximum value, or less than a minimum value, the air temperature regulating valve opening is adjusted, which can not only avoid system overpressure damage, but also avoid the large temperature fluctuation at the bottom of the drying tower caused by the pressure real-time regulating valve, further improving the drying efficiency and safety.

[0073] In an exemplary embodiment, the target bed temperature is 55°C and the real-time bed temperature is 50°C. The heat required to increase the bed temperature from 50°C to 55°C is calculated, and then the hot air temperature corresponding to the heat injected within 1 minute (adjustment time) is calculated to be a°C (generally, the wind speed is fixed, so the heat corresponding to the same hot air temperature per unit time is fixed, so it is only necessary to adjust the hot air temperature). The corresponding optimization control parameter is a°C for the target hot air temperature, and a 1-minute adjustment time is maintained. After 1 minute, the target hot air temperature is dynamically adjusted according to the system heat loss, so that the heat brought by the hot air is balanced with the loss. This achieves accurate drying control of the polymerization drying system at each time step (control link), so as to increase the probability that each batch of objects to be dried can meet the drying standards after drying, and reduce the situation of unqualified drying.

[0074] See also Figure 2 , Figure 2 This is a schematic diagram of a process flow of a polymerization drying control method provided in an exemplary embodiment of the present application, such as Figure 2As shown, first, the attribute parameters of the object to be dried are set, that is, the category of the object to be dried (such as polyvinyl chloride) and the weight of the object to be dried (system feed amount), as well as the bed temperature setting value of the tower bed area of ​​the drying tower and the bottom setting temperature of the airflow pipe of the airflow pipe for outflowing hot air. Secondly, the object to be dried is fed into the tower bed area of ​​the drying tower according to the weight of the object to be dried and the category of the object to be dried, and the hot air of the initial temperature of the system is injected into the tower bed area of ​​the drying tower, and the bed temperature of the tower bed area, the bottom temperature of the airflow pipe of the airflow pipe, the hot air temperature of the airflow pipe and the steam pressure (the real-time steam pressure is directly observed by the steam pressure observer) are detected in real time, and the real-time bed temperature, the real-time bottom temperature of the airflow pipe, the real-time hot air temperature of the airflow pipe and the real-time steam pressure are obtained, and the real-time operating parameters are obtained. At the same time, the hot air injected into the drying tower dries the object to be dried in the tower bed area, passes through the airflow pipe and flows out from the air temperature regulating valve. In addition, the drying tower is also equipped with a matching hand operator, which allows the staff to control the control parameters of the polymerization drying system at any time to achieve the desired drying tower operating parameters and to promptly respond to abnormal problems caused by control failure or internal damage to the drying tower. Figure 2 The SP in it represents the set temperature value, and the PV represents the measured temperature value.

[0075] Then, the measured real-time operating parameters are input into the target drying model for processing to obtain target operating parameters, including target bed temperature, target airflow tube bottom temperature, target airflow tube hot air temperature and target steam pressure, and based on the target operating parameters, optimized control parameters are obtained, including target hot air temperature and target air temperature regulating valve opening, and the hot air temperature is adjusted based on the target hot air temperature, and the air temperature regulating valve is adjusted based on the target air temperature regulating valve opening, so that the bed temperature in the tower bed area reaches the target bed temperature, the airflow tube bottom temperature of the airflow tube reaches the target airflow tube bottom temperature, the airflow tube hot air temperature of the airflow tube reaches the target airflow tube hot air temperature, and the steam pressure of the airflow tube reaches the target steam pressure, so as to control the drying temperature, system temperature and system pressure, realize safe and stable polymerization drying of the object to be dried, and improve the stability and safety of the drying system.

[0076] In this embodiment, when the object to be dried is PVC, since the decomposition temperature of PVC is about 190 degrees, the drying temperature is usually about 60-70 degrees, and PVC is a heat-sensitive raw material, the drying time should not be too long, generally about two hours. In addition, the glass transition temperature and thermal degradation temperature of the PVC resin itself are relatively low, and the temperature of the material layer should not exceed 70 degrees during drying. The focus of drying PVC should be on temperature distribution. During the drying period, attention should be paid to making the temperature distribution of the internal space of the drying tower uniform, and controlling the retention of particles to achieve polymerization drying without dead ends in the drying tower. Therefore, the collection interval of the real-time operating parameters can be set to 5 minutes, 10 minutes, etc. Therefore, the control interval for controlling the polymerization drying system based on the target operating parameters corresponds to 5 minutes, 10 minutes, etc.
