[0002] The resin used by the condensate polishing system greatly determines the water quality effect of the treated condensate. If the separation effect of the positive and negative resins is poor, a large amount of positive resin is mixed in the negative resin, and a large amount of negative resin is mixed in the positive resin, which further causes permanent pollution and damage to the positive and negative resins during the acid and alkali regeneration, respectively.

[0003] In order to study the resin operation effect and change rule of the condensate polishing high-speed mixed bed, improve the water and steam quality of the unit, and avoid the influence on the corrosion, salt accumulation and pipe explosion of various thermal equipment, it is necessary to carry out related test research on resin separation.

[0004] The resin regeneration workshop of the power plant is always in a production state, and the device is made of stainless steel material, so it is impossible to check the running state of the internal resin and provide test conditions for the research on resin separation. Therefore, it is necessary to study and invent a test device for simulating resin high tower separation, which can accurately simulate the dynamic separation of the high tower, effectively solve the problem of difficult test in the power plant, and test different types and proportions of resins. By recording the flow, flow rate and sedimentation of resin separation, the resin separation effect is judged through online image recognition, which is beneficial to selecting resins with good separation effect and providing basis and solution for solving the problem of difficult separation of various resins.

DETAILED DESCRIPTION

[0048] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application.

[0049] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0050] Embodiment 1, refer to Figures 1-2 For an embodiment of the present application, a dynamic simulation test device for resin high-tower separation is provided, comprising:

[0051] The high-tower separation dynamic simulation experiment device provided by the present application comprises a desalted water tank 100, a booster pump 200, a remote flow meter 300, a control cabinet and start-stop switch 400, a separation tower 500, a resin storage tank 600, valve 700 (number #1-#14), a camera 800, a resin interface intelligent identification and control device 900;

[0052] The water outlet at the bottom of the desalted water tank 100 is connected to the upper water inlet and the bottom water inlet of the separation tower 500 through the booster pump 200 and the remote flow meter 300 respectively; wherein the signal line of the remote flow meter is connected to the resin interface intelligent identification and control device 900.

[0053] As shown in Figure 2 The valve 700 (number #1-#14) can control the desalted water delivery flow rate by the size of its opening.

[0054] The backwash flow rate of each set of different proportion brand resin needs to be determined according to the density and particle size of the resin itself.

[0055] The opening adjustment of valve 1# can control the water tank water flow rate, and the opening adjustment of valve 2# can control the flow rate into the separation tower.

[0056] The booster pump 200 is connected to the control cabinet and start-stop switch 400, and by starting the pump and opening different valves, the desalted water can be delivered into the separation tower through the upper water inlet or the lower water inlet.

[0057] The top cover of the separation tower 500 can be opened and closed, and resin can be added. When there is resin and desalted water in the separation tower, water can be introduced from the bottom by a booster pump to start the backwashing and layering of the mixed anion and cation resins. The backwashing and layering requires controlling the flow rate from large to small by controlling the opening of the valve 700 to achieve the state of “upward pressure and downward dragging” of the resin backwashing, which is beneficial to the layering of the resins.

[0058] The fat outlet at the bottom of the separation tower 500 is connected to the resin storage tank 600 through a valve and a pipeline, and the upper fat inlet and the bottom fat outlet of the resin storage tank 600. By starting the booster pump, water is transported from the upper part, and resin is pressed into the resin storage barrel from the lower part. In addition, under the condition that the separation tower is full of water, the booster pump is used to pump water from the upper part of the separation tower to form a negative pressure state, so that the resin enters the bottom of the separation tower from the bottom fat outlet of the resin storage barrel.

[0059] The camera 800 is placed on the side of the peephole of the separation tower 500, and the camera 800 is connected with the resin separation interface intelligent identification and control device 900 for monitoring the separation interface of the mixed anion and cation resins after the backwashing and layering, identifying and recording the color moment value of the separation interface, and obtaining the data of the flow meter. The high-definition camera technology is used to monitor the separation process of the resins, automatically judge the separation process of the resins, and send signals to the program control system to realize the separation of the mixed resins in the separation tower.

[0060] The separation tower made of acrylic material is transparent, and the separation movement state of the resins being washed by water can be observed. The separation tower in the power plant is made of stainless steel with an inner rubber lining due to the pressure requirement, and only a peephole is provided for observing the local separation interface.

[0061] The simulation device has a small volume and requires a small amount of resin for testing, and can simulate various resin separation tests. The on-site separation tower is large, about 10 m high, and can accommodate 6-10 m3 of resin at a time. The peephole is generally in the middle, and a large amount of resin must be added to observe the separation interface, which is not conducive to the test. The simulation test device effectively avoids this problem.

[0062] The judgment of the separation process of the resins includes that the color of the anion and cation resins is different, and a clear horizontal separation line appears, indicating good separation effect; no separation interface appears, indicating no separation; and the curved separation line indicates that the identification is not successful.

[0063] The color difference of the upper and lower colors of the separation line is the color moment value calculated by real-time image recognition.

[0064] The camera recognizes the resin image of the peephole of the separation tower, compares the color moment values of the real-time anion and cation separation interface images, and sets the color moment value in the control system to 30. When the recognition value is greater than 30, it is judged that the separation interface is recognized. If it is less than 30, it is judged that it is not recognized.

[0065] The control system sends a signal to the program control system to realize the separation of the mixed resins in the separation tower. Figure 1The composition, water in and out, and resin in and out are separated.

[0066] The regeneration of the power plant is a set of mixed resin 6-10m 3 The amount is large, and the price is 10-30 million; and through the test device of the application, only a few tens of liters of amount are required at a time, and various resins are conveniently matched for testing.

[0067] The image recognition control system of the traditional method does not access the flow signal, the flow signal is accessed in the application, the flow rate is calculated in the control device, and the flow and flow rate data are stored, and the color moment of the image recognition control device is combined to comprehensively judge the resin separation effect.

[0068] As Figure 2 As shown in the figure, in order to quickly and accurately identify and judge the layering effect of the positive and negative resins in the resin high tower separation process, the application designs a deep neural network model to identify and finely segment and locate the separation interface. The neural network model YOLO-Unet is composed of YOLO and U-Net network. Among them, YOLO is used to quickly detect the approximate area of the resin boundary line, and U-Net is used to accurately segment the pixel level in the area to obtain the specific position of the boundary line. Through this division of labor, the system can balance the real-time and accuracy of identification.

[0069] The model processes from three steps of data collection, model training and actual application:

[0070] (1) Image data collection

[0071] Camera equipment: install a high-definition camera in the resin separation tower to capture the image of the resin boundary line in real time. It is recommended to collect images under different experimental conditions to ensure the generalization ability of the model.

[0072] Image annotation: annotate the collected images. The annotation information includes the accurate position of the boundary line (segmentation annotation) and the area of the boundary line (bounding box annotation), which is used as the basic data for training YOLO and U-Net.

[0073] Physical data collection: record experimental parameters such as flow rate u, flow Q, cross-sectional area S, etc. in each group of experiments as auxiliary data input.

[0074] (2) Data enhancement

[0075] Since the performance of the resin boundary line may differ under different environments, data enhancement can be used to increase the diversity of data, such as rotation, flipping, scaling and brightness adjustment to generate more training samples.

[0076] (3) Neural network training

[0077] The target of YOLO is to quickly detect the approximate position of the resin demarcation line. Training YOLO requires using an image dataset with demarcation line annotations and optimizing the target detection loss function. The input of the network is the preprocessed resin separation column image, and the output is the predicted box of the demarcation line, which predicts the area of the demarcation line. In the present application, the CIOU loss function is used to measure the difference between the predicted box and the real box. CIoU is an IoU-based loss function that not only considers the overlapping area between the predicted box and the real box, but also considers the center point distance and the difference in aspect ratio between them:

[0078]

[0079] wherein, ρ(b,b * ) is the distance between the center points of the predicted box and the real box, c is the diagonal length of the smallest enclosing box that can enclose the two boxes, α is a weight factor, and v is the difference in height ratio.

[0080] For the classification loss, a binary cross-entropy loss is used for training to identify whether the target pixel is a demarcation line:

[0081] L B =-[ylog(p)+(1-y)log(1-p)]

[0082] wherein, y is the real label (1 represents the demarcation line and 0 represents the background). p represents the predicted probability, which represents the probability that a certain candidate box contains the demarcation line. 1-p represents the probability of being background. The third part of the loss is the confidence loss, which measures whether the predicted box contains the target object and also considers the background area. In the present application, a binary cross-entropy loss is used for learning:

[0083]

[0084] wherein, y is the real label, if the predicted box contains the target, then y=1; if the predicted box does not contain the target, then y=0. is the predicted confidence, i.e. the probability of whether there is a target in the predicted box. Through the combination of these three loss functions, the final training is completed.

[0085] The task of the U-Net is to perform accurate pixel-level segmentation on the basis of the area provided by YOLO, and to identify the specific shape of the resin separation line. The accuracy of the U-Net comes from its encoder-decoder structure and skip connections. This architecture enables the U-Net to retain high-resolution spatial information during image dimension reduction, while combining deep semantic information for fine-grained segmentation. Finally, a binary image with the same size as the input image is output, representing the separation line and the background. The value of each pixel is 0 (background) or 1 (separation line). Then use Opencv to extract the contour of the separation line, and then calculate whether there is a separation case N and the color difference matrix M. Combine the color difference matrix M to calculate the color difference of the resin on both sides of the separation line. By comparing the colors on both sides of the separation line, the color difference value is calculated to evaluate the resin separation effect.

[0086] The image recognition control system of the traditional method does not access the flow signal, and the flow signal is accessed in the application, the flow rate is calculated in the control device, and the flow and flow rate data are stored, and the color moment of the image recognition control device is combined to comprehensively judge the resin separation effect.

[0087] The flow meter signal is connected to the resin intelligent recognition control device; the flow, flow rate, and color moment recognition are comprehensively combined to determine.

[0088] The analysis control unit obtains the data Q of the remote flow meter 300 and calculates the backwashing water inflow rate, which is represented as,

[0089] u = Q / S

[0090] Wherein, S represents the cross-sectional area of the separation tower;

[0091] The resin separation effect is judged by online image recognition, combined with the separation identification color moment M of each set of test mixed resin and whether the resin separation is identified N, to evaluate whether the resin meets the separation requirements, determine the best separation flow and flow rate of the mixed resin, and select the resin with good separation effect.

[0092] Judgment steps:

[0093] (1) Color moment value M >= 120, separation limit clear N = 2, the resin separation effect of this set of mixed ratio is good

[0094] (2) Color moment value 30 <= M < 120, separation limit relatively clear N = 1, the resin separation effect of this set of mixed ratio is good

[0095] (3) Color moment value M < 30, separation limit not clear N = 0, the resin separation effect of this set of mixed ratio is poor

[0096] (4) The control device records the M, N, and u values of each mixed resin ratio test and stores them in the database

[0097] (5) According to the database, comparison analysis can be performed to select resins and proportions suitable for field use.

[0098] Example 2, refer to Figure 3 According to an embodiment of the present application, a dynamic simulation test method for resin high column separation is provided, comprising:

[0099] Step 1, connect the high column separation dynamic simulation test device electrical control cabinet to the power supply, check the pipeline valve opening and closing and the normal state of the electrical control cabinet.

[0101] Step 3, the initial state of the high column separation dynamic simulation test device: all the default valves are closed, the flow is controlled by controlling the valve opening; the resin interface intelligent identification and control device is powered on for testing, remote access testing and camera position fine adjustment.

[0102] Step 4, operate the valves and start and stop the water pump on the separation column simulation test device to achieve the following functions:

[0103] Step 4.1.1, add resin through the top inlet of the separation column;

[0104] Step 4.1.2, open valves #1, #2, #3, start the water pump switch, and open the exhaust valve #14; when the water flows out of valve #14, the separation column is full of water, and water flows into the upper part of the separation column.

[0105] Step 4.1.3, open valves #1, #2, #3, #4, #5, start the water pump switch, and realize the separation column resin unloading;

[0106] Step 4.1.4, open valves #1, #2, #7, start the water pump switch. Water flows into the lower part of the separation column, and resin backwashing is performed. The flow is controlled from large to small by controlling the valve opening, and the flow data is transmitted to the resin interface intelligent identification and control device to realize the resin supporting and layering function: after backwashing separation, the resin interface intelligent identification and control device is used for identification, the color matrix between the positive and negative resins can be identified, and the positive and negative resin layering interface can be judged;

[0107] Step 4.1.5, open valves #1, #2, #3, #11, start the water pump switch; water flows out of the lower part of the separation column:

[0108] Step 4.1.6, open valves #2, #7, #10, and the high column drains.

[0109] Step 4.1.7, open valves #4, #8, #9, #10, and start the water pump switch; the negative pressure state draws resin from the bottom of the resin barrel, which can achieve the suction of resin from the bottom of the resin barrel, water from the upper part of the separation tower, and discharge from the No. 10 valve after pumping.

[0110] Step 4.2.1, mixed test for different brands and types of positive and negative resins to determine the effect of backwashing separation. The water flow rate is from large to small, that is, the flow rate is from large to small, and all the resins are first flushed into the funnel section at the top of the separation tower, and different particles with different settling speeds are sequentially dropped by gradually reducing the backwashing water rising flow rate, so as to separate the positive and negative resins. Record the flow data and feed it back to the resin interface intelligent identification and control device to calculate the water flow rate and adjust the valve, and record the picture and color matrix value of the resin separation corresponding to each flow or flow rate.

[0111] Step 4.3.1, test different proportions (for example, positive and negative ratio 1:1, 2:1, 3:1) for the same brand of positive and negative resins to determine the effect of backwashing separation. The water flow rate is from large to small, that is, the flow rate is from large to small, and all the resins are first flushed into the funnel section at the top of the separation tower, and different particles with different settling speeds are sequentially dropped by gradually reducing the backwashing water rising flow rate, so as to separate the positive and negative resins. Record the flow data and feed it back to the resin interface intelligent identification and control device to calculate the water flow rate and adjust the valve, and record the picture and color matrix value of the resin separation corresponding to each flow or flow rate.

[0112] Step 4.4.1, open valves #1, #2, #7, and start the water pump switch. Water is introduced into the lower part of the separation tower to perform resin backwashing, and the flow rate is controlled from large to small by controlling the valve opening, and the flow data is transmitted to the resin interface intelligent identification and control device to realize the resin separation and layering function: after backwashing separation, the resin interface intelligent identification and control device can identify the color matrix between the positive and negative resins, and judge the positive and negative resin layering interface.

[0113] This operation is the function of backwashing; backwashing various proportions of resins to determine separation; the resin interface intelligent identification and control device judges the color matrix of the separation; and the flow rate, flow rate, and color matrix data determine the separation effect of the test proportion of positive and negative mixed resins.
