Description

Technical Field

[0001] The invention relates to the technical field of coal preparation, and in particular to a coal slurry water control device. Background Art

[0002] Coal is the main energy source in my country and an important pillar of the national economy. Coal preparation is the process of sorting coal to remove mineral impurities from raw coal and obtain products of different specifications to improve the utilization rate of raw coal and meet the needs of different customers. With the continuous mining of coal, high-quality coal resources are decreasing year by year. In order to improve sustainable development, the mining of low-quality coal resources is increasing year by year.

[0003] In the process of mining low-quality coal resources, the quality of raw coal is unstable, the coal slime content is high, and there are many impurities, which in turn causes the quality of the coal slime water washed from the raw coal to be unstable, making it very difficult to treat. The treatment of coal slime water is an important link in the production process of the coal preparation plant, which directly affects the production efficiency and environmental protection of the coal preparation plant.

[0004] Coal slime water treatment usually includes steps such as concentration, flocculation, and dehydration. In this process, dosing is a key link. The appropriate dosage can improve the efficiency of coal slime water treatment and reduce environmental pollution. However, due to the unstable quality of coal slime water, the existing coal slime water control system often cannot adjust the dosage in time, resulting in insufficient or excessive dosage.

[0005] Insufficient dosing will lead to poor treatment of coal slime water, high coal slime content in overflow water, and increased risk of environmental pollution. Excessive dosing will cause waste of reagents and increase production costs. In addition, inappropriate dosing may also affect the quality of coal slime and reduce its economic value.

[0006] The existing coal slurry water control system cannot keep up with the changes in coal slurry water quality, resulting in waste of dosing and increased production costs. In this case, operators often need to manually adjust the dosage based on experience, which not only increases labor intensity, but also makes it difficult to ensure the consistency and stability of the treatment effect.

[0007] In addition, the existing coal slurry water control system usually lacks real-time monitoring and intelligent control functions, and cannot respond to changes in coal slurry water quality in a timely manner. This makes it difficult for the system to adapt to the coal slurry water treatment needs under different coal types and different working conditions, affecting the overall production efficiency of the coal preparation plant.

[0047] The existing coal slurry water control system has poor automatic control adaptability and cannot respond to changes in coal slurry water quality in a timely and appropriate manner, which easily leads to waste of reagents and increased production costs. This application proposes a coal slurry water control device, which realizes automatic and accurate addition of reagents through the cooperation of multiple sensors and controllers, thereby improving production efficiency and cost-effectiveness.

[0048] The technical problem solved by this application is how to achieve accurate and automated control of adding reagents to coal slime water during coal slime water treatment. Figure 1 to Figure 2 As shown, the present application provides a coal slurry water control device including a concentration tank, a coal slurry water dosing device and a coal slurry dehydration device. The concentration tank 10 includes a concentration tank body 11, a liquid inlet pipe 12 and a coal slurry concentration bottom flow pipe 13, wherein the liquid inlet pipe 12 is located above the concentration tank body 11 and communicates with the concentration tank body 11, and the coal slurry concentration bottom flow pipe 13 is located below the concentration tank body 11 and communicates with the concentration tank body 11; the coal slurry water dosing device 20 shown includes a flow meter 21, a density meter 22, an interface meter 23, a turbidity meter 24, a dosing device 25 and a controller 26, wherein the flow meter 21 is arranged on the liquid inlet pipe 12, and the flow meter 21 is used to obtain the flow information of the coal slurry water flowing through the liquid inlet pipe 12, the density meter 22 is arranged on the liquid inlet pipe 12, and the density meter 22 is used to obtain the density information of the coal slurry water flowing through the liquid inlet pipe 12, the interface meter 23 is arranged in the concentration tank body 11, and the interface meter 23 is used to In order to obtain the position information of the solid-liquid interface in the concentrating tank body 11, the turbidity meter 24 is movably arranged in the concentrating tank body 11 along the depth direction of the concentrating tank body 11, and the turbidity meter 24 is used to obtain the information of the turbidity degree of the liquid at different depths in the concentrating tank body 11, the drug delivery device 25 is connected with the concentrating tank body 11, and the drug delivery device 25 is used to add the agent into the concentrating tank body 11, the controller 26 is respectively connected with the flow meter 21, the density meter 22, the interface meter 23, the turbidity meter 24 and the drug delivery device 25, and is used to collect the information obtained by the flow meter 21, the density meter 22, the interface meter 23 and the turbidity meter 24, and control the drug delivery device 25 to add the agent into the concentrating tank body 11; the coal slime dehydration device 30 is connected with the coal slime concentrating bottom flow pipe 13, and the coal slime dehydration device 30 is used for coal slime collection and dehydration treatment.

[0049] The concentrating tank of the present application is used to contain and concentrate coal slime water to ensure the separation of coal slime and water. The coal slime water dosing device obtains the flow rate, density, solid-liquid interface position and turbidity information of the coal slime water through a flow meter, a density meter, an interface meter and a turbidity meter, and processes this information through a controller, thereby accurately controlling the dosing device to add reagents to the concentrating tank. The coal slime dehydration device is used to further process the concentrated coal slime, dehydrate it and collect it.

[0050] In the process of treating coal slime water, the traditional thickening tank intermittently adds reagents to the thickening tank through the dosing pump. Workers adjust the dosing intervals and control the dosage by measuring the interface of coal slime water in the thickening tank and observing the clarity of overflow water based on manual experience. With the development of technology, coal preparation plants have adopted automatic control equipment, which can obtain the parameter information of the raw coal slime water entering the coal slime tank and the parameter information of the precipitated coal slime water in the coal slime tank through electromagnetic flowmeters, electronic concentration pots, sludge interface meters, turbidity meters and other equipment. Generally, the dosage is calculated by combining the predetermined ratio information with the parameter information of the raw coal slime water, and the dosage is adjusted. The parameter information of the precipitated coal slime water in the coal slime tank is used as the limited predetermined information to issue an early warning for values ​​outside the range.

[0051] The controller in the coal slime water dosing device in this embodiment includes an acquisition module, a data preprocessing module, a model training module and a dosing control module. The acquisition module is respectively connected to the flow meter, the density meter, the interface meter and the turbidity meter, and is used to collect information obtained by these devices. The data preprocessing module is connected to the acquisition module, and is used to preprocess the collected data. The model training module is connected to the data preprocessing module, and is used to obtain external data and preprocessed data, and train and construct a linear regression model. The dosing control module is respectively connected to the model training module and the dosing device, and is used to receive the dosing results given by the model training module and control the dosing device to add drugs into the concentration tank according to the results.

[0052] In this embodiment, the linear regression model creation process may include:

[0053] 1. Data Collection

[0054] Determine the independent and dependent variables related to the dosage of the thickener. The dependent variable is the dosage of the thickener, recorded as y; the independent variables include the mud flow rate, recorded as x 1 ; Inlet sludge concentration, denoted as x 2 ; Turbidity, recorded as x 3 ; pH value, recorded as x 4 .

[0055] According to the preset time interval, the sludge flow rate, sludge concentration, turbidity, pH value and corresponding dosage data of the thickening tank are collected, and the data are collected continuously for a certain period of time, such as 4-12 months, to cover different working conditions and seasonal changes. The sludge flow rate can be measured using an electromagnetic flow sensor, such as Emerson's Rosemount 8700 series. The measurement range is determined according to the actual sludge flow rate, with an accuracy of ±0.5%, which is used to measure the flow of sludge or slurry entering the thickening tank. It is installed on the sludge inlet pipeline. The sludge concentration is measured by a nuclear radiation concentration meter, such as Dandong Oriental Measurement and Control's DFC-200, with a measurement range of 0-50%, and its parameters can be adjusted according to actual conditions, with an accuracy of ±0.5%, which is used to measure the concentration of the sludge. Installed on the sludge inlet pipeline to ensure accurate measurement. Turbidity is measured by a turbidity meter, such as Hach's sc200 turbidity meter, with a measurement range of 0-1000NTU and an accuracy of ±0.01NTU, which is used to monitor the turbidity of the liquid in the thickening tank in real time. It is installed at the outlet of the concentration tank to ensure that the turbidity of the supernatant after precipitation is measured. The dosage is obtained through the flow metering device of the dosing pump.

[0056] 2. Data preprocessing

[0057] The first step is data cleaning: check whether there are missing values ​​or outliers in the collected data. For missing values, you can use mean filling, median filling or interpolation filling based on other data; for outliers, you can identify and process them by setting a reasonable threshold range (such as mean ± 3 times standard deviation), and you can choose to delete outliers or make corrections.

[0058] The second is data standardization: Since the dimensions and value ranges of different independent variables may vary greatly, in order to improve the performance of the linear regression model, the data needs to be standardized. Commonly used standardization methods include Z-score standardization, the formula is Where X is the original data, μ is the mean, and σ is the standard deviation.

[0059] 3. Model building

[0060] The first step is to divide the data set: divide the preprocessed data into a training set and a test set according to a certain ratio (such as 70%-30% or 80%-20%). The training set is used to train the model, and the test set is used to evaluate the performance of the model.

[0061] The second is the linear regression model: Assuming that the dosage y and the mud flow rate x 1 , inlet sludge concentration x 2 , turbidity x 3 and pH x 4 There is a linear relationship between them, and the expression of the linear regression model is y = β 0 +β 1 x 1 +β2 x 2 +β 3 x 3 +β 4 x 4 +∈, where β 0 Intercept, β 1 , β 2 , β 3 , β 4 is the regression coefficient and ∈ is the error term.

[0062] Finally, the model is trained, using the training set data to estimate the regression coefficient β through methods such as least squares. 0 , β 1 , β 2 , β 3 , β 4 .

[0063] 4. Model Evaluation

[0064] The test set is used to evaluate the model performance, and the mean square error (MSE) and the coefficient of determination (R 2 ), and evaluate the model.

[0065] 5. Dosage prediction and application

[0066] Predicting dosage: In practical applications, the values ​​of independent variables such as mud flow rate, mud concentration, turbidity and pH value are obtained in real time, and input into the trained linear regression model to get the predicted dosage.

[0067] Dosing control: According to the predicted dosage, adjust the operating parameters of the dosing equipment (such as the dosing pump) to achieve accurate control of the dosage of the concentration tank. At the same time, continuously monitor the actual dosing effect and related operating parameters, and regularly update and optimize the model based on feedback information to adapt to changes in working conditions.

[0068] The acquisition module is responsible for acquiring data information from flow meters, densitometers, interface meters, and turbidity meters, which are the basis for dosing control. The data preprocessing module preprocesses the collected data to ensure the accuracy and consistency of the data, which is crucial for model training. The model training module uses the preprocessed data and external data to train the linear regression model and generate a dosing strategy. The dosing control module accurately controls the dosing amount of the dosing device based on the dosing results provided by the model training module, thereby achieving effective control of coal slime water.

[0069] In terms of implementation, the acquisition module can transmit data with flow meters, densitometers, interface meters and turbidity meters through standard industrial communication protocols to ensure the real-time and accuracy of data. The data preprocessing module can use common data processing methods such as filtering, denoising, and normalization to improve the quality of data. The model training module can use historical data and external data for model training based on machine learning algorithms to generate a linear regression model for dosing control. The dosing control module can accurately adjust the dosing amount by controlling valves or pumps to ensure the accuracy and timeliness of dosing.

[0070] Through the above scheme, the present application solves the technical problems of data collection, preprocessing, model training and dosing control in the coal slime water control device, ensures the precise control of the dosing amount, improves the efficiency and effect of coal slime water treatment, reduces the waste of reagents, and reduces production costs. Compared with the prior art, the technical solution of the present application significantly improves the accuracy and response speed of dosing control by introducing data preprocessing and model training modules, and can better adapt to changes in coal slime water quality, thereby achieving more stable and efficient coal slime water treatment.

[0071] Furthermore, the present application also proposes that the dosing device 25 includes a dosing box 25-1, a dosing flow regulating valve 25-2 and a dosing pipe 25-3, the dosing box 25-1 is used to store predetermined medicines, the dosing pipe 25-3 is connected to the dosing box 25-1 through the dosing flow regulating valve 25-2, and the dosing flow regulating valve 25-2 is used to adjust the amount of predetermined medicines entering the dosing pipe 25-3, the dosing pipe 25-3 is at least partially located below the liquid level in the concentration tank body 11, and is used to add the predetermined medicines to the liquid in the concentration tank body 11.

[0072] The medication box 25-1 includes a first medication box and a second medication box, and the first medication box and the second medication box are used to store flocculants and coagulants respectively; the medication flow regulating valve 25-2 includes a first medication flow regulating valve and a second medication flow regulating valve; the first medication flow regulating valve is connected to the first medication box through management, and the second medication flow regulating valve is connected to the second medication box through a pipeline; the medication pipe 25-3 includes a first medication pipe and a second medication pipe, the first medication pipe is connected to the first medication flow regulating valve, and the second medication pipe is connected to the second medication flow regulating valve.

[0073] Specifically, the dosing box can be made of corrosion-resistant materials to prevent the medicine from corroding the box body. The dosing flow regulating valve can use a high-precision regulating valve to ensure accurate control of the dosage. The installation position of the dosing pipeline should ensure that at least part of it is located below the liquid level in the concentration tank body, so that the medicine can directly enter the liquid to ensure the effective use of the medicine. In addition, the material of the dosing pipeline should also be corrosion-resistant to extend its service life. As a preferred embodiment, the dosing pipeline can be divided into multiple sections, one of which is located outside the concentration tank body and the other is located below the liquid level, and is connected by a connector to facilitate installation and maintenance.

[0074] The present application divides the medication box into two independent parts, storing different medicines (flocculants and coagulants) respectively, and realizes independent control of different medicines through independent flow regulating valves and pipeline systems. The first medication box and the second medication box store flocculants and coagulants respectively, ensuring independent storage and management of medicines. The independent setting of medication flow regulating valves allows the flow of each medicine to be adjusted separately, ensuring precise control of the dosing process. The independent design of medication pipelines allows different medicines to be transported through their respective pipeline systems to avoid mixing and contamination.

[0075] Furthermore, the first medication box and the second medication box can be designed with different materials to adapt to the chemical properties of different medicines. For example, the storage box of the flocculant can be made of corrosion-resistant materials, while the storage box of the coagulant can be made of high-strength materials. The medication flow control valve can be an electric or pneumatic control valve to achieve more precise flow control. The material and diameter of the medication pipeline can be selected according to the characteristics of the medicine and the flow requirements to ensure the stability and reliability of the delivery process.

[0076] The present application achieves precise control of dosing during the treatment of coal slime water by improving the dosing device, avoiding waste of reagents and reducing production costs. At the same time, through an independent pipeline system, the mixing and contamination of different reagents are avoided, and the treatment effect is improved. Compared with the prior art, the present application provides a more efficient and accurate dosing control system for coal slime water treatment, solving the problems of inaccurate dosing, reagent waste and contamination in the prior art.

[0077] Furthermore, the present application also proposes that the coal slurry water dosing device 20 also includes a pH sensor 27, which is arranged on the liquid inlet pipe 12, and the pH sensor 27 is used to obtain the pH value information of the coal slurry water flowing through the liquid inlet pipe 12, and the pH sensor 27 is connected to the acquisition module 26-1, and the pH sensor 27 is used to transmit the pH value information of the coal slurry water obtained by the pH sensor 27 to the acquisition module 26-1.

[0078] The pH sensor is arranged on the liquid inlet pipe, and is used to obtain the pH value information of the coal slurry water flowing through the liquid inlet pipe. The sensor is connected to the acquisition module, and can transmit the acquired pH value information to the acquisition module. By adding a pH sensor, the pH value of the coal slurry water can be monitored in real time, and the information can be transmitted to the acquisition module, so that the pH value information can be subsequently introduced into the linear regression model, and the dosing ratio of two different agents can be regulated by the pH value to ensure the accuracy of the dosage, avoid the waste of agents, improve the processing efficiency, and reduce the production cost. Compared with the prior art, the present application can predict the dosing ratio of two different agents according to the linear regression model, thereby improving the accuracy of dosing, reducing the waste of agents, improving the processing efficiency, and reducing the production cost. In this way, the treatment process of coal slurry water is more efficient and economical.

[0079] Furthermore, the present application also proposes that the coal slurry water dosing device 20 also includes an underflow concentration meter 28, which is installed on the coal slurry concentration underflow pipe 13, and the underflow concentration meter 28 is used to obtain the concentration information of the concentrated underflow coal slurry water. The underflow concentration meter 28 is connected to the acquisition module 26-1, and the underflow concentration meter 28 is used to transmit the concentrated underflow coal slurry water concentration information of the coal slurry water in the concentration tank body 11 obtained by the underflow concentration meter 28 to the acquisition module 26-1.

[0080] The present application adds an underflow concentration meter to the coal slime water dosing device, and the underflow concentration meter is installed on the coal slime concentration underflow pipe to obtain the concentration information of the concentrated underflow coal slime water. The underflow concentration meter is connected to the acquisition module and can transmit the acquired concentration information to the acquisition module. In this way, the concentration of the concentrated underflow of the coal slime water can be monitored in real time, and the underflow concentration information is also added to the linear regression model. By controlling the dosage and the feed amount of the raw coal slime, the underflow slime concentration is controlled to provide suitable coal slime for the filter press in the next process, thereby improving the coal slime sedimentation effect while improving the coal slime dehydration efficiency and reducing the energy consumption of the equipment.

[0081] Underflow densitometers can use a variety of types of sensors, such as ultrasonic densitometers, electromagnetic densitometers, or optical densitometers. These sensors are able to provide reliable concentration measurement data in complex coal slurry water environments. Specifically, ultrasonic densitometers use the propagation speed and attenuation characteristics of ultrasound to measure the concentration of coal slurry water; electromagnetic densitometers determine the concentration by measuring the effect of suspended particles in coal slurry water on electromagnetic waves; and optical densitometers obtain concentration information by measuring the scattering and absorption of light by coal slurry water.
