These methods are not only cumbersome to operate and slow to connect, but may also have problems such as loose connection and easy leakage. Especially in high temperature and high pressure working environments, the risk of leakage is higher, affecting the safety and reliability of the system. At the same time, during the steam-water separation process, components such as fine wire mesh plates are prone to adhere to impurities and dirt, affecting the steam-water separation effect.

[0007] As a further solution of the present invention: the quick connection mechanism is rotatably connected to the side fixing block via a rotating block.

[0008] As a further solution of the present invention: the movable paddle is slidably connected inside the paddle slot, one end of the support spring is connected to the fixed spring block, and the other end is fixedly connected inside the spring block slot, the groove opened on the side of the fixed block is adapted to the positioning block, and the top of the fixed block is wedge-shaped, which is convenient for squeezing the positioning block into the spring block slot.

[0009] As a further solution of the present invention: a through hole slightly larger than the diameter of the soda inlet pipe is opened inside the first gear, and a through hole slightly larger than the diameter of the soda inlet pipe is opened inside the fourth gear.

[0010] As a further solution of the present invention: the rotating fixed block and the cleaning brush are provided in four groups, and the cleaning brush is in contact with the fine wire mesh plate.

[0011] As a further solution of the present invention: the first gear is meshed with the second gear, and the third gear is meshed with the fourth gear.

[0012] As a further solution of the present invention: the diameter of the bottom of the shielding cover is slightly smaller than the diameter of the main cavity to allow liquid to pass through.

[0013] The present invention also discloses a method for using a steam-water separator inside a boiler, comprising the following steps:

[0014] Step 1: Before starting the steam-water separation process, first use the quick connection mechanism to connect the steam-water inlet pipe and the external pipe, rotate the upper arc-shaped fixing plate to make it fit with the clamp ring of the external pipe, and then rotate the lower arc-shaped fixing plate to make it fit with the clamp ring of the external pipe. During this process, the fixed card block will squeeze the positioning card block into the spring block groove, and the positioning card block will clamp the groove on the side of the fixed card block to achieve the quick connection of the steam-water inlet pipe and the external pipe. The traction force of the two sets of spring rods ensures the close fit between the steam-water inlet pipe and the external pipe, preventing liquid and steam leakage;

[0015] Step 2: The steam-water mixture is introduced into the main cavity through the steam-water inlet pipe. Inside the main cavity, the steam-water mixture begins the preliminary steam-water separation process. The fan blades installed on the side of the steam-water inlet pipe start to rotate under the drive of the dual-rotor motor to generate a wind field. This wind field helps the steam in the steam-water mixture to rise, while the liquid part sinks due to gravity. At the same time, the shielding cover under the steam-water inlet pipe prevents the droplets from being attracted by the wind field generated by the fan blades and floating up, thereby further ensuring the effect of steam-water separation, thereby initially realizing steam-water separation. A fine wire mesh plate is also provided in the steam-water inlet pipe, which is composed of a mesh material composed of filamentary materials. When the droplet diameter is larger than the gap between the wire meshes, they cannot pass through the wire mesh and are intercepted. For droplets of small diameter, due to the certain viscosity of water and the irregular shape of the droplets at high speed, they will be "bridged" due to their own tension when passing through the gap composed of the wire mesh, thereby being intercepted, further improving the efficiency of steam-water separation.

[0016] Step 3: The rotating shaft under the dual-rotor motor drives the third gear to rotate, and the fourth gear meshed with the third gear also starts to rotate. The rotating fixed block under the fourth gear rotates accordingly, and then drives the cleaning brush to rotate on the fine wire mesh plate. This structure helps to remove impurities that may be attached to the fine wire mesh plate and ensure that the soda enters the tube unobstructed;

[0017] Step 4: After steam-water separation, the steam is discharged through the steam outlet pipe, while the liquid part remains in the main cavity. When the liquid in the main cavity accumulates to a certain level, the separated water can be discharged by controlling the liquid outlet valve.

[0018] Furthermore, a method for adjusting the steam-water separator inside the boiler is added. In step 1, the quick connection mechanism is automatically operated by intelligent sensors and algorithms. Image recognition technology is used to detect the docking status of the steam-water inlet pipe (3) and the external pipe (7), and the positions of the upper arc-shaped fixing plate (63) and the lower arc-shaped fixing plate (64) are automatically adjusted by a machine learning algorithm to achieve the best sealing and connection effect. This can reduce the complexity of the operation and the need for manual adjustment. The specific steps are as follows:

[0019] Step 1: System components and hardware configuration

[0020] Smart sensors and cameras: Choose industrial-grade cameras with higher resolution and high frame rates to ensure continuous images of high-speed actions can be captured.

[0021] Distance sensor: Laser distance sensor, with high measurement accuracy requirements, is used to accurately control and detect the distance between the soda inlet pipe and the external pipe.

[0022] Pressure sensor: Use a pressure sensor with an accuracy of ±0.01bar to monitor and record pressure changes during the connection process to evaluate sealing performance.

[0023] Hardware interface: Use an industrial computer with high-speed processing power, equipped with a good-performance GPU to support complex machine learning calculations and real-time data processing.

[0024] Step 2: Data collection and preprocessing

[0025] The following parameters were recorded during each connection operation: video image sequence, distance sensor readings at each stage, pressure sensor readings. Initially, data was collected for at least 1000 connection operations, including both successful and failed cases.

[0026] The video of each operation is annotated, including marking the time points of successful or failed connection and the relevant sensor readings, as well as the correct position of the fixing plate.

[0027] Step 3: Build and train the machine learning model

[0028] Define the CNN architecture and parameter ranges:

[0029] CNN architecture selection:

[0030] Basic architecture: A network architecture with a sequence of multi-layer convolutional layers, batch normalization layers, ReLU activation layers, max pooling layers, and two fully connected layers is selected. Such a structure ensures sufficient model complexity to capture complex image features.

[0031] Output layer: Classification or regression is performed as needed, and the last layer selects the softmax function to meet the needs of the recognition task.

[0032] Parameters include:

[0033] Learning rate: affects the speed at which the model weights are updated.

[0034] Batch size: Smaller batches provide more frequent updates, while larger batches improve memory utilization and computational efficiency.

[0035] Number of filters: affects the feature extraction capability of the model.

[0036] Filter size: determines the size of the local field of view for feature extraction.

[0037] Initialize the whale population:

[0038] Population size: Set a certain number of whales, and the "position" of each whale is a hyperparameter configuration.

[0039] Random initialization: Each hyperparameter is randomly initialized within its specified range to ensure the diversity of the population.

[0040] Fitness evaluation:

[0041] Build the model: Build a CNN model based on the position (hyperparameter set) of each whale. The specific construction steps are as follows:

[0042] The position X of each whale i , represents a set of specific CNN hyperparameters. These hyperparameters include:

[0043] Learning rate (η), batch size (B), number of filters (F n ), filter size (F s )

[0044] Next, we build a CNN model based on the hyperparameter set, use the selected learning rate η and Adam optimization, compile the optimizer to prepare for training, and Optimizer is the optimizer formula:

[0045] Optimizer = Adam(η)

[0046] The last step is training and evaluation: each model is trained using the labeled data set, and its performance is evaluated on the validation set, using the mean square error as the fitness evaluation.

[0047] Update whale position:

[0048] Surround the prey strategy (narrow the search area):

[0049] X i,new =X * -A·|C·X * -X i |

[0050] Spiral update strategy (simulating the spiral feeding behavior of whales):

[0051] X i,new =|X * -X i |·e b·l ·cos(2πl)+X *

[0052] Where b = 1 is the helical constant, which is used to control the tightness of the helical behavior, and A and C are calculated according to the following formula:

[0053] A=2a·ra

[0054] C=2q

[0055] X i,new It is the new location of the whale after the update;

[0056] X i is the position of the i-th whale, representing a set of hyperparameters of CNN;

[0057] X * is the optimal set of hyperparameters found so far;

[0058] A is a coefficient matrix that controls the amplitude of the search step and affects how close the whale is to the optimal solution or the random direction;

[0059] C is another coefficient matrix used to calculate the distance between the target whale and the current whale position;

[0060] l is a random number in the interval [-1,1], which is used in the spiral update strategy to determine the direction and amplitude of the spiral rise or fall;

[0061] a is a coefficient that decreases linearly with the iteration process. It is used to control the value of A and affects the globality and locality of the search.

[0062] r and q are random numbers in the interval [0,1], which are used to dynamically adjust the values ​​of A and C to increase the randomness and diversity of the search process;

[0063] Random or Exploration Updates: The algorithm decides to explore new areas and the whales will randomly move towards or away from the best solution, which helps to escape from local optima.

[0064] Termination condition: Repeat steps 3 and 4 until the maximum number of iterations and fitness are reached, and there is no significant improvement in consecutive generations.

[0065] Step 4: Implementation and automatic adjustment

[0066] Design of control algorithm:

[0067] First, the goal: to use stepper motors to precisely control the position of the curved fixing plate to enable fast and precise docking with external pipes.

[0068] Implementation:

[0069] Design a closed-loop control system that dynamically adjusts the number and direction of the stepper motor based on the prediction data obtained from the model in step three.

[0070] A PID (Proportional-Integral-Derivative) controller is used to achieve this. A PID controller adjusts the control output based on the deviation, which is the difference between the desired position and the actual position.

[0071]

[0072] in:

[0073] u(t) is the control input (drive signal of the stepper motor) at time t;

[0074] e(t) is the deviation at time t, that is, the difference between the predicted position and the current position;

[0075] e(τ) represents the error or deviation in the past time period τ (from 0 to the current time t);

[0076] K p , K i , K d They are the proportional, integral, and derivative gains of the PID controller;

[0077] Real-time feedback control:

[0078] Real-time data processing, the machine learning model predicts in real time where the curved fixing plate should be and sends the position difference (deviation) to the control system.

[0079] Stepper motor adjustment:

[0080] According to the driving signal u(t) calculated by the PID algorithm, the stepper motor adjusts its steps and direction to minimize the position deviation.

[0081] The control resolution of the stepper motor determines the accuracy of the adjustment. Each step of the stepper motor corresponds to a small adjustment in the position of the fixed plate.

[0082] Step 5: Monitoring and maintenance

[0083] User Interface: Develop a graphical user interface (GUI) that displays real-time data, operating status, historical trend graphs, and suggested warnings or adjustments.

[0084] Maintenance interface: provides system performance log, error report and maintenance reminder functions.

[0085] Compared with the prior art, the present invention has the following beneficial effects:

[0086] 1. The quick connection mechanism of the present invention can quickly and conveniently realize the connection between the steam-water inlet pipe and the external pipeline. At the same time, the traction force of the two sets of spring rods ensures the tightness of the connection, effectively preventing the leakage of liquid and steam, and improving the safety and reliability of the system.

[0087] 2. In the present invention, a dual-rotor motor drives the cleaning brush to rotate on the fine wire mesh plate, which can automatically remove impurities that may be attached to the fine wire mesh plate, keep the soda and water inlet pipe unobstructed, reduce the trouble of manual cleaning, and improve the operating efficiency of the equipment.

[0088] 3. The wind field system composed of the fan blades and the dual-rotor motor arranged in the steam-water inlet pipe and the shielding cover under the steam-water inlet pipe in the present invention significantly improves the efficiency of steam-water separation. The wind field generated by the fan blades helps the steam to rise and the liquid to sink, while the shielding cover prevents the droplets from floating up, thus ensuring the effect of steam-water separation.

[0089] 4. Through the application of intelligent control technology, this patent effectively improves the automation and accuracy of the docking operation between the soda inlet pipe and the external pipeline, significantly improves the accuracy and efficiency of the operation, and reduces the need for manual operation and possible errors. In addition, the overall reliability of the system is improved, and the technical level and market competitiveness are also enhanced accordingly. These implementation details not only optimize product performance, but also help to highlight its innovation and technological advancement in patent applications, bringing obvious economic and technical benefits to users and the industry.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of its embodiments based on the overall structure of the present invention.

[0101] Reference Figures 1 to 7In an embodiment of the present invention, a steam-water separator inside a boiler comprises: a main shell 1, a main cavity 2 is opened inside the main shell 1, a steam-water inlet pipe 3 is fixedly connected to the outside of the main shell 1, a steam outlet pipe 4 is fixedly connected to the outside of the main shell 1, two sets of side fixing blocks 5 are fixedly connected to the outside of the steam-water inlet pipe 3 and the steam outlet pipe 4, a quick connection mechanism 6 is arranged on the side of the side fixing block 5, an external pipeline 7 is arranged on the side of the steam-water inlet pipe 3, and a liquid outlet valve 18 is fixedly connected to the bottom of the main shell 1 to control the discharge of the separated water inside the main cavity 2;

[0102] The quick connection mechanism 6 includes a rotating block 61, through which the quick connection mechanism 6 is rotatably connected to the side fixing block 5, a spring rod 62 is fixedly connected to the side of the rotating block 61, an upper arc-shaped fixing plate 63 is fixedly connected to the movable end of the spring rod 62, a lower arc-shaped fixing plate 64 is rotatably connected below the upper arc-shaped fixing plate 63, a fixed clamping block 65 is fixedly connected to the lower arc-shaped fixing plate 64, a spring block groove 66 is provided below the upper arc-shaped fixing plate 63, a paddle groove 67 is provided on the side of the spring block groove 66 that penetrates to the side of the upper arc-shaped fixing plate 63, and a spring block groove 66 is provided inside. A fixed spring block 68 is slidably connected, a support spring 69 is fixedly connected to the side of the fixed spring block 68, a movable paddle 610 is fixedly connected to the side of the fixed spring block 68, a locking block 611 is fixedly connected to the side of the fixed spring block 68, the movable paddle 610 is slidably connected inside the paddle slot 67, one end of the support spring 69 is connected to the fixed spring block 68, and the other end is fixedly connected inside the spring block slot 66, the groove on the side of the fixed block 65 is adapted to the locking block 611, and the top of the fixed block 65 is wedge-shaped, which is convenient for squeezing the locking block 611 into the spring block slot 66.

[0103] The above scheme is adopted: when the quick connection mechanism 6 is not in use, the lower arc-shaped fixing plate 64 is not fixed to the upper arc-shaped fixing plate 63. When it is necessary to connect the soda inlet tube 3 with the external pipe 7, it is only necessary to rotate the upper arc-shaped fixing plate 63 to fit the clamping ring of the external pipe 7. At this time, the lower arc-shaped fixing plate 64 is rotated to fit the clamping ring of the external pipe 7. At this time, the fixed block 65 will squeeze the positioning block 611 into the spring block groove 66. The positioning block 611 clamps the groove on the side of the fixed block 65 to complete the fixation. The traction force of the two sets of spring rods 62 ensures that the soda inlet tube 3 is tightly attached to the external pipe 7 to prevent liquid leakage and steam leakage. When disassembly is required, it is only necessary to move the movable paddle 610 so that the positioning block 611 no longer clamps the groove on the side of the fixed block 65. The connection between the soda inlet tube 3 and the external pipe 7 can be released by rotating the lower arc-shaped fixing plate 64.

[0104] Reference Figure 1 and Figure 5A fan blade 8 is rotatably connected to the side of the soda inlet pipe 3, a first gear 9 is fixedly connected below the fan blade 8, a through hole slightly larger than the diameter of the soda inlet pipe 3 is opened inside the first gear 9, a dual-rotor motor 10 is fixedly connected to the side of the soda inlet pipe 3, a second gear 11 is fixedly connected to the rotating shaft above the dual-rotor motor 10, a third gear 12 is fixedly connected to the rotating shaft below the dual-rotor motor 10, a fine wire mesh plate 13 is fixedly connected to the side of the soda inlet pipe 3 below the third gear 12, a fourth gear 14 is rotatably connected to the side of the soda inlet pipe 3 above the fine wire mesh plate 13, a through hole slightly larger than the diameter of the soda inlet pipe 3 is opened inside the fourth gear 14 A through hole with a diameter of the water inlet pipe 3 is provided, a rotating fixed block 15 is fixedly connected below the fourth gear 14, a cleaning brush 16 is fixedly connected below the rotating fixed block 15, and four groups of rotating fixed blocks 15 and cleaning brushes 16 are arranged, the cleaning brush 16 is fitted with the fine wire mesh plate 13, a shielding cover 17 is fixedly connected below the steam-water inlet pipe 3, the first gear 9 is meshed with the second gear 11, the third gear 12 is meshed with the fourth gear 14, the diameter of the bottom of the shielding cover 17 is slightly smaller than the diameter of the main cavity 2 to allow liquid to pass through, and the shielding cover 17 can prevent droplets from being attracted and floating by the wind field generated by the fan blades 8 to affect the effect of steam-water separation.

[0105] The above scheme is adopted: the dual-rotor motor 10 is turned on, the upper rotating shaft drives the second gear 11 to rotate, and then drives the first gear 9 and the fan blades 8 to rotate to generate a wind field, and the lower rotating shaft drives the third gear 12 to rotate, and then drives the fourth gear 14 and the rotating fixed block 15 to rotate, so that the cleaning brush 16 rotates on the fine wire mesh plate 13 to remove impurities that may be attached, and the shielding cover 17 prevents the droplets from being attracted by the wind field generated by the fan blades 8 to float up, so as to ensure the effect of gas-water separation.

[0106] A method for using a steam-water separator inside a boiler comprises the following steps:

[0107] Step 1: Before starting the steam-water separation process, first use the quick connection mechanism 6 to connect the steam-water inlet pipe 3 and the external pipe 7, rotate the upper arc-shaped fixing plate 63 to make it fit with the clamp ring of the external pipe 7, and then rotate the lower arc-shaped fixing plate 64 to make it fit with the clamp ring of the external pipe 7. In this process, the fixed clamp block 65 will squeeze the positioning clamp block 611 into the spring block groove 66, and the positioning clamp block 611 will clamp the groove on the side of the fixed clamp block 65, so as to realize the quick connection between the steam-water inlet pipe 3 and the external pipe 7. The traction force of the two sets of spring rods 62 ensures the close fit between the steam-water inlet pipe 3 and the external pipe 7, and prevents the phenomenon of liquid leakage and steam leakage;

[0108] Step 2: The steam-water mixture is introduced into the main cavity 2 through the steam-water inlet pipe 3. Inside the main cavity 2, the steam-water mixture begins a preliminary steam-water separation process. The fan blades 8 installed on the side of the steam-water inlet pipe 3 start to rotate under the drive of the dual-rotor motor 10, generating a wind field. This wind field helps the steam in the steam-water mixture to rise, while the liquid part sinks due to gravity. At the same time, the shielding cover 17 below the steam-water inlet pipe 3 prevents the droplets from being attracted by the wind field generated by the fan blades 8 and floating up, thereby further ensuring the effect of steam-water separation, thereby preliminarily realizing steam-water separation. A fine wire mesh plate 13 is also provided in the steam-water inlet pipe 3, which is composed of a mesh material composed of filamentary materials. When the droplet diameter is larger than the gap between the wire meshes, they cannot pass through the wire mesh and are intercepted. For droplets of small diameter, due to the certain viscosity of water and the irregular shape of the droplets at high speed, they will be "bridged" due to their own tension when passing through the gap composed of the wire mesh, thereby being intercepted, further improving the efficiency of steam-water separation.

[0109] Step 3: The rotating shaft under the dual-rotor motor 10 drives the third gear 12 to rotate, and the fourth gear 14 meshing with the third gear 12 also starts to rotate. The rotating fixed block 15 under the fourth gear 14 rotates accordingly, and then drives the cleaning brush 16 to rotate on the fine wire mesh plate 13. This structure helps to remove impurities that may be attached to the fine wire mesh plate 13, ensuring that the soda enters the pipe 3 unobstructed;

[0110] Step 4: After steam-water separation, the steam is discharged through the steam outlet pipe 4, while the liquid portion remains in the main cavity 2. When the liquid in the main cavity 2 accumulates to a certain extent, the separated water can be discharged by controlling the liquid outlet valve 18.

[0111] Furthermore, a method for adjusting the steam-water separator inside the boiler is added, and the quick connection mechanism is automatically operated by an intelligent sensor and an algorithm. In step 1, the quick connection mechanism is automatically operated by an intelligent sensor and an algorithm. Image recognition technology is used to detect the docking condition between the steam-water inlet pipe (3) and the external pipe (7), and the position of the upper arc-shaped fixing plate (63) and the lower arc-shaped fixing plate (64) is automatically adjusted by a machine learning algorithm to achieve the best sealing and connection effect. This can reduce the complexity of the operation and the need for manual adjustment. The specific steps are as follows:

[0112] Step 1: System components and hardware configuration

[0113] Smart sensors and cameras: Choose industrial-grade cameras with a resolution of 1080p or higher and a frame rate of at least 60fps to ensure that continuous images of high-speed actions can be captured.

[0114] Distance sensor: Laser distance sensor, measuring accuracy ±0.1mm, used to accurately control and detect the distance between the soda inlet pipe and the external pipe.

[0115] Pressure sensor: Use a pressure sensor with an accuracy of ±0.01bar to monitor and record pressure changes during the connection process to evaluate sealing performance.

[0116] Hardware interface: Use industrial computers with high-speed processing capabilities, equipped with NVIDIA GPUs to support complex machine learning calculations and real-time data processing.

[0117] Step 2: Data collection and preprocessing

[0118] The following parameters were recorded during each connection operation: video image sequence, distance sensor readings at each stage, pressure sensor readings. Initially, data was collected for at least 1000 connection operations, including both successful and failed cases.

[0119] The video of each operation is annotated, including marking the time points of successful or failed connection and the relevant sensor readings, as well as the correct position of the fixing plate.

[0120] Step 3: Build and train the machine learning model

[0121] Define the CNN architecture and parameter ranges:

[0122] CNN architecture selection:

[0123] Basic architecture: A network architecture with a sequence of multi-layer convolutional layers, batch normalization layers, ReLU activation layers, max pooling layers, and two fully connected layers is selected. Such a structure ensures sufficient model complexity to capture complex image features.

[0124] Output layer: Classification or regression is performed as needed, and the last layer selects the softmax function to meet the needs of the recognition task.

[0125] Parameter range:

[0126] Learning rate: from 0.0001 to 0.01.

[0127] Batch size: from 16 to 128.

[0128] Number of filters: The number of filters in each convolutional layer ranges from 32 to 512.

[0129] Filter size: from 3x3 to 7x7.

[0130] Initialize the whale population:

[0131] Population size: Set the number of whales to 30. The "position" of each whale is a hyperparameter configuration.

[0132] Random initialization: Each hyperparameter is randomly initialized within its specified range to ensure the diversity of the population.

[0133] Fitness evaluation:

[0134] Build the model: Build a CNN model based on the position (hyperparameter set) of each whale. The specific construction steps are as follows:

[0135] The position X of each whale i , represents a set of specific CNN hyperparameters. These hyperparameters include:

[0136] Learning rate (η), batch size (B), number of filters (F n ), filter size (F s )

[0137] The selection range for each parameter is:

[0138] η∈[0.0001,0.01]

[0139] B∈[16,128]

[0140] F n ∈[32,512]

[0141] F s ∈{3×3,5×5,7×7}

[0142] Next, we build a CNN model based on the hyperparameter set, use the selected learning rate η and Adam optimization, compile the optimizer to prepare for training, and Optimizer is the optimizer formula:

[0143] Optimizer = Adam(η)

[0144] The last step is training and evaluation: each model is trained using the labeled data set, and its performance is evaluated on the validation set, using the mean square error as the fitness evaluation.

[0145] Update whale position:

[0146] Surround the prey strategy (narrow the search area):

[0147] X i,new =X * -A·|C·X * -X i |

[0148] Spiral update strategy (simulating the spiral feeding behavior of whales):

[0149] X i,new =|X * -X i |·e b·l ·cos(2πl)+X *

[0150] Where b = 1 is the helical constant, which is used to control the tightness of the helical behavior, and A and C are calculated according to the following formula:

[0151] A=2a·ra

[0152] C=2q

[0153] X i,new It is the new location of the whale after the update;

[0154] X i is the position of the i-th whale, representing a set of hyperparameters of CNN;

[0155] X * is the optimal set of hyperparameters found so far;

[0156] A is a coefficient matrix that controls the amplitude of the search step and affects how close the whale is to the optimal solution or the random direction;

[0157] C is another coefficient matrix used to calculate the distance between the target whale and the current whale position;

[0158] l is a random number in the interval [-1,1], which is used in the spiral update strategy to determine the direction and amplitude of the spiral rise or fall;

[0159] a is a coefficient that decreases linearly with the iteration process. It is used to control the value of A and affects the globality and locality of the search.

[0160] r and q are random numbers in the interval [0,1], which are used to dynamically adjust the values ​​of A and C to increase the randomness and diversity of the search process;

[0161] Random or Exploration Updates: The algorithm decides to explore new areas and the whales will randomly move towards or away from the best solution, which helps to escape from local optima.

[0162] Termination condition: Repeat steps 3 and 4 until the maximum number of iterations, 100, and a certain fitness are reached, and there is no significant improvement in consecutive generations.

[0163] Step 4: Implementation and automatic adjustment

[0164] Design of control algorithm:

[0165] First, the goal: to use stepper motors to precisely control the position of the curved fixing plate to enable fast and precise docking with external pipes.

[0166] Implementation:

[0167] Design a closed-loop control system that dynamically adjusts the number and direction of the stepper motor based on the prediction data obtained from the model in step three.

[0168] This is accomplished using a PID (proportional-integral-derivative) controller. A PID controller adjusts the control output based on the deviation, which is the difference between the desired position and the actual position.

[0169]

[0170] in:

[0171] K p , K i , K d Set to 0.1, 0.01, and 0.005 respectively

[0172] Real-time feedback control:

[0173] Real-time data processing, the machine learning model predicts in real time where the curved fixing plate should be and sends the position difference (deviation) to the control system.

[0174] Stepper motor adjustment:

[0175] According to the driving signal u(t) calculated by the PID algorithm, the stepper motor adjusts its steps and direction to minimize the position deviation.

[0176] The control resolution of the stepper motor determines the accuracy of the adjustment. Each step of the stepper motor corresponds to a slight adjustment of the position of the fixed plate, achieving an accuracy of no more than 0.1mm.

[0177] Step 5: Monitoring and maintenance

[0178] User Interface: Develop a graphical user interface (GUI) that displays real-time data, operating status, historical trend graphs, and suggested warnings or adjustments.

[0179] Maintenance interface: provides system performance log, error report and maintenance reminder functions.

[0180] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

9. A method for using a steam-water separator inside a boiler, characterized in that: It includes the following steps: Step 1: Before starting the steam-water separation process, first use the quick connection mechanism (6) to connect the steam-water inlet pipe (3) and the external pipe (7), rotate the upper arc-shaped fixed plate (63) to make it fit with the clamping ring of the external pipe (7), and then rotate the lower arc-shaped fixed plate (64) to make it fit with the clamping ring of the external pipe (7). In this process, the fixed block (65) will squeeze the positioning block (611) into the spring block groove (66), and the positioning block (611) will clamp the groove on the side of the fixed block (65), so as to realize the quick connection between the steam-water inlet pipe (3) and the external pipe (7). The traction force of the two sets of spring rods (62) ensures the close fit between the steam-water inlet pipe (3) and the external pipe (7), and prevents the phenomenon of liquid leakage and steam leakage; Step 2: The steam-water mixture is introduced into the main cavity (2) through the steam-water inlet pipe (3). Inside the main cavity (2), the steam-water mixture begins a preliminary steam-water separation process. The fan blades (8) installed on the side of the steam-water inlet pipe (3) start to rotate under the drive of the dual-rotor motor (10), generating a wind field. This wind field helps the steam in the steam-water mixture to rise, while the liquid part sinks due to gravity. At the same time, the shielding cover (17) below the steam-water inlet pipe (3) prevents the droplets from being attracted by the wind field generated by the fan blades (8) and floating up, thereby further The step ensures the effect of steam-water separation, thereby preliminarily achieving steam-water separation. A fine wire mesh plate (13) is also provided in the steam-water inlet pipe (3), which is composed of a mesh material composed of filamentary materials. When the diameter of the droplets is larger than the gap between the wire meshes, they cannot pass through the wire meshes and are intercepted. For droplets with small diameters, due to the certain viscosity of water and the irregular shape of the droplets at high speed, when they pass through the gaps formed by the wire meshes, they will be "bridged" due to their own tension, thereby being intercepted, thereby further improving the efficiency of steam-water separation. Step 3: The rotating shaft below the dual-rotor motor (10) drives the third gear (12) to rotate, and the fourth gear (14) meshed with the third gear (12) also starts to rotate. The rotating fixed block (15) below the fourth gear (14) rotates accordingly, thereby driving the cleaning brush (16) to rotate on the fine wire mesh plate (13). This structure helps to remove impurities that may be attached to the fine wire mesh plate (13) and ensure that the soda enters the pipe (3) unobstructed; Step 4: After steam and water are separated, the steam is discharged through the steam outlet pipe (4), while the liquid portion remains in the main cavity (2). When the liquid in the main cavity (2) accumulates to a certain level, the separated water can be discharged by controlling the liquid outlet valve (18).
