Detailed Implementation

[0021] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0022] The adaptive optimization method, apparatus, electronic device, and storage medium of the system according to embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0023] Figure 1 This is a flowchart illustrating an adaptive optimization method for a system provided in an embodiment of this disclosure.

[0024] like Figure 1 As shown, the method includes the following steps: Step 101: Collect real-time data on particle size, bulk density, and moisture content of the ash material; The particle size of ash refers to the size and distribution of ash particles. Ash particles of different sizes exhibit different flow characteristics during pneumatic conveying. Fine-grained ash is more easily carried by airflow, while coarse-grained ash requires higher airflow velocities to avoid sedimentation. Bulk density refers to the mass per unit volume of ash, directly reflecting its compactness. Ash with high bulk density requires greater airflow thrust during conveying to overcome its gravity and inter-particle friction. Moisture content refers to the water content of the ash. Ash with excessive moisture content is prone to particle agglomeration, increasing conveying resistance and even raising the risk of pipe blockage. To achieve real-time data acquisition, the system deploys corresponding detection devices at key nodes in the ash conveying path, such as the silo pump outlet and below the ash hopper. For example, a particle size sensor using laser diffraction is used to monitor the particle size distribution of the ash in real time, a density sensor is used to obtain the bulk density data of the ash in real time, and a moisture sensor is used to continuously monitor the moisture content of the ash. These detection devices can quickly respond to changes in ash characteristics, transmitting the collected particle size, bulk density, and moisture data to the system's control unit in real-time. This provides accurate and timely raw data support for the subsequent dynamic generation of a three-dimensional characteristic map of ash quantity (t / h) × pressure loss (kPa) × ash-to-gas ratio, ensuring that the map accurately reflects the actual characteristics of the ash. This lays the data foundation for adaptive gas volume control, effectively addressing the problem of ash characteristic changes caused by coal quality fluctuations, and avoiding the drawbacks of high energy consumption and easy pipe blockage caused by the use of fixed gas volume configuration in traditional systems due to the lack of real-time ash characteristic data.

[0025] Step 102: Construct a three-dimensional dynamic ash characteristic map based on the particle size, bulk density, moisture content data and coal quality parameters of the ash material; The particle size, bulk density, and moisture content of ash, as key parameters directly reflecting the physical properties of ash, provide real-time dynamic data support for map construction: particle size distribution determines the suspension and flowability of ash in airflow, bulk density reflects the compactness of ash and the thrust required for conveying, and moisture content is related to the agglomeration tendency and conveying resistance characteristics of ash. Coal quality parameters, especially ash content, are core factors affecting the essential properties of ash. A coal quality-map mapping library is established to achieve precise adaptation of map types—when the ash content is >25%, the ash often exhibits higher compactness and conveying difficulty. In this case, the system automatically uses pre-stored high-density ash maps to ensure that the maps can specifically match the ash characteristics under high-ash coal conditions.

[0026] The coordinate axes of the three-dimensional dynamic ash material characteristic map are clearly defined as ash content (t / h) × pressure loss (kPa) × ash-to-gas ratio. Ash content represents the amount of ash transported per unit time, pressure loss reflects the pipeline pressure loss during transport, and the ash-to-gas ratio reflects the proportional relationship between ash mass and transport gas flow rate. These three elements together constitute the core dimensions describing the ash material transport status. During map construction, the system first uses pre-stored basic characteristic maps as an initial reference based on real-time collected particle size, bulk density, moisture data, and current coal quality parameters. Then, it enters a dynamic correction stage. When the deviation between the measured pressure loss and the map's estimated value is greater than 10%, the system updates the map parameters in real time according to the preset formula "new ash-to-gas ratio = original ash-to-gas ratio × (measured pressure loss / estimated pressure loss) 0.8," ensuring that the map can dynamically track subtle changes in ash material characteristics. Through this construction process, the three-dimensional dynamic ash material characteristic map can reflect the correlation between ash content, pressure loss and ash-to-gas ratio under different ash material characteristics and coal quality parameters in a real and real time. It provides an accurate characteristic benchmark for subsequent adaptive gas volume control, effectively solves the problem of unreasonable gas volume configuration caused by rigid ash material characteristic characterization in traditional systems, and lays a key characteristic understanding foundation for coping with the ash transportation challenges brought about by coal quality fluctuations.

[0027] Step 103: Based on the dynamic ash material characteristic spectrum and pressure gradient data, the ash conveying gas volume is optimized in real time using a dual-constraint optimization algorithm.

[0028] The dynamic ash characteristic map provides a precise benchmark for ash characteristics for gas volume optimization. This three-dimensional map uses ash content (t / h) × pressure loss (kPa) × ash-to-gas ratio as the coordinate axis, reflecting in real time the ash conveying characteristics under the correlation of current ash particle size, bulk density, moisture content, and coal quality parameters (such as coal ash content). For example, when the coal ash content is >25% and the high-density ash map is activated, the map will output a reference range of ash-to-gas ratio suitable for high-density ash, providing an initial characteristic basis for gas volume optimization. The pressure gradient data is acquired in real time by pressure sensors deployed every 3 meters along the ash conveying pipeline. It reflects the pressure change trend at different locations in the pipeline. The pressure difference ΔP between adjacent sensors can intuitively reflect abnormal changes in ash flow resistance. For example, an increase in ΔP may indicate the risk of local pipe blockage, providing real-time operating condition feedback for the algorithm.

[0029] The dual-constraint optimization algorithm uses "minimizing total gas volume" as its core objective function, i.e., min(total gas volume) = f(ash quantity, ash mass, pipe pressure). It aims to solve the problem of excessive gas supply under low load caused by the fixed gas volume configuration of traditional systems, reducing energy consumption through dynamic adjustment of gas volume. Simultaneously, the algorithm sets two key constraints to ensure ash conveying safety: first, the terminal velocity ≤ 15 m / s. The terminal velocity is the airflow velocity at the end of the ash conveying pipeline; excessively high velocity will significantly exacerbate wear on the inner wall of the pipeline. This constraint avoids excessive equipment wear by limiting the terminal airflow velocity. Second, the starting Froude number ≥ 1.25. The Froude number is a dimensionless parameter reflecting the ratio of airflow inertial force to ash weight. Insufficient Froude number at the ash conveying start (such as the outlet of a silo pump) will lead to insufficient ash fluidization and particle agglomeration. This constraint ensures that the ash can be effectively carried by the airflow, preventing pipe blockage from the source.

[0030] In the specific optimization process, the algorithm first calls the parameters such as the current ash volume, ash-to-gas ratio, and estimated pressure loss output from the dynamic ash characteristic map. Combined with the actual pipe pressure changes monitored by the pressure gradient data (e.g., when the deviation between the measured pressure loss and the map's estimated value is >10%, the ash-to-gas ratio after dynamic correction of the map is referenced), the algorithm calculates the initial gas volume value under the current operating conditions in real time. Then, it performs verification and adjustment based on dual constraints: if the final velocity corresponding to the calculated gas volume exceeds 15 m / s, the gas volume is reduced until the anti-wear constraint is met; if the initial Froude number is less than 1.25, the gas volume is appropriately increased to enhance fluidization carrying capacity until the anti-clogging constraint is met. Through this collaborative optimization logic of "characteristic map as the benchmark, pressure gradient to adjust operating conditions, and dual constraints to ensure safety," the algorithm can output the optimal gas volume value in real time that meets the current ash conveying requirements and minimizes energy consumption when coal quality fluctuations cause changes in ash characteristics. This effectively overcomes the industry pain points of rigid gas volume configuration, high energy consumption, and pipe clogging and wear in traditional systems.

[0031] In some embodiments, after optimizing the ash conveying gas volume in real time using a dual-constraint optimization algorithm based on the dynamic ash material characteristic spectrum and pressure gradient data, the method further includes: The utilization rate of each gray pipe is calculated based on the operating status of multiple gray pipes. When the utilization rate is lower than the set threshold, the pipe borrowing mechanism is activated, and the gas volume after the pipe borrowing is adjusted through the gas volume redistribution formula to achieve load balancing and collaborative optimization among multiple gray pipes.

[0032] By monitoring the actual operating data of each ash pipe in real time, the utilization rate of each ash pipe is calculated. The formula for calculating the utilization rate η is defined as η = actual ash volume / design throughput. This formula directly reflects the ratio of the actual ash conveying volume of the ash pipe to the maximum designed ash conveying capacity. A higher η value indicates that the ash pipe is fully loaded, while a low η value means that the ash pipe has idle capacity. The system sets a utilization rate threshold (e.g., η < 60%). When the utilization rate of a certain ash pipe is detected to be lower than this threshold, it indicates that the ash pipe is not fully utilizing its ash conveying capacity. At this time, the pipe borrowing mechanism is activated, that is, the ash material from other high-load ash pipes (such as the ash material generated by the second electric field) is transferred to the low-utilization ash pipe (such as the first electric field pipe) for transportation through system scheduling. This achieves a reasonable distribution of ash material transportation tasks among multiple ash pipes and avoids the situation where some ash pipes are overloaded while others are idle.

[0033] To ensure stable and efficient ash conveying after pipe borrowing, the system precisely adjusts the air volume after pipe borrowing using an air volume redistribution formula: Air volume after pipe borrowing = Original air volume * (1 = Borrowed ash volume / Original ash volume) 0.7. Here, "Original air volume" refers to the air volume value of the ash pipe before pipe borrowing, optimized by a dual-constraint optimization algorithm; "Borrowed ash volume" is the ash volume transferred from other ash pipes to this ash pipe; and "Original ash volume" is the actual ash conveying volume of the ash pipe before pipe borrowing. The exponent of 0.7 in the formula is based on experiments on ash conveying characteristics, aiming to balance the relationship between air supply and ash volume increase—when the borrowed ash volume increases, the air volume increases non-linearly, ensuring sufficient airflow thrust to carry the new ash while avoiding excessive air volume increase leading to increased energy consumption or excessive terminal velocity. Through this air volume redistribution mechanism, the air volume of the ash pipe after pipe borrowing can dynamically adapt to the conveying needs of the new ash, ensuring that key parameters such as ash-to-air ratio, terminal velocity, and starting Froude number still meet system constraints.

[0034] In summary, by calculating the utilization rate of the ash pipes and initiating the pipe borrowing mechanism when the utilization rate is low, and adjusting the gas volume in conjunction with the gas volume redistribution formula, this step achieves load balancing among multiple ash pipes, reduces the phenomenon of peak gas volume superposition, improves the resource utilization efficiency and operational stability of the overall ash conveying system, and further optimizes the collaborative operation performance of the pneumatic ash conveying system.

[0035] In some embodiments, the construction of a three-dimensional dynamic ash characteristic map based on the particle size, bulk density, moisture data, and coal quality parameters of the ash further includes: The ash content parameters of the ash material characteristic spectrum are dynamically adjusted by using boiler load signal, dust collector secondary current signal and ash hopper weighing signal as real-time signal inputs.

[0036] The boiler load signal (in MW) directly reflects the real-time operating load status of the boiler. An increase in boiler load means an increase in coal consumption, and correspondingly, an increase in ash production; conversely, a decrease in load means a decrease in coal consumption and a decrease in ash production. As an important correlated variable of ash content parameters, this signal can capture the overall fluctuation trend of ash content caused by changes in boiler operating intensity in real time, providing a basis for macroscopic adjustments of ash content parameters in the graph.

[0037] The secondary current signal (in A) of the dust collector is closely related to the dust removal efficiency and ash collection status of the dust collector. Changes in the secondary current can indirectly reflect the ash adsorption of the electrodes inside the dust collector. When the secondary current fluctuates abnormally, it may indicate that there is an instantaneous change in the amount of ash entering the ash conveying system (such as a sudden increase in the amount of ash during the electrode cleaning). The system senses the dynamic fluctuation of the amount of ash through this signal and helps to correct the instantaneous value of the ash amount parameter in the spectrum.

[0038] The ash hopper weighing signal (unit: t / h) directly measures the mass flow rate of the ash material to be conveyed in the ash hopper in real time. It is the most direct source of measured data for ash quantity parameters. Its value directly corresponds to the current actual ash material conveying volume of the ash conveying system, providing the core basis for the accurate setting of ash quantity parameters in the graph.

[0039] During the construction of the three-dimensional dynamic ash characteristic map, these real-time signals are continuously input into the system control unit, working in conjunction with the particle size, bulk density, moisture content, and coal quality parameters of the ash. The system first calls the pre-stored basic map based on the coal quality parameters, then predicts the overall trend of ash content through the boiler load signal, obtains the real-time actual ash content by combining the ash hopper weighing signal, and then verifies the ash content fluctuation through the dust collector secondary current signal. After integrating the dynamic changes in ash content reflected by these signals, the parameter value of the "ash content (t / h)" coordinate axis in the map is adjusted in real time to ensure that the ash content parameter in the map is always consistent with the actual ash generation and conveying status of the current ash conveying system. This provides an accurate ash content benchmark for subsequent adaptive gas volume control and avoids unreasonable gas volume configuration caused by lag or deviation in ash content parameters.

[0040] In some embodiments, before optimizing the ash conveying gas volume in real time using a dual-constraint optimization algorithm based on the dynamic ash material characteristic spectrum and pressure gradient data, the method includes: The pressure gradient data is obtained by collecting pressure under different operating conditions based on preset sensors.

[0041] Pre-set sensors refer to pressure detection devices that are pre-deployed at key locations in the ash conveying system according to a specific layout. Specifically, pressure sensors are installed at the outlet of the silo pump and every 3 meters along the ash conveying pipeline. These sensors reuse the interface of a DN20 turbulence valve. This layout comprehensively covers the critical path of ash material from the silo pump discharge to pipeline transport, ensuring full-range monitoring of pressure changes within the pipeline. Sensor sampling and processing are supported by the system control architecture. Each ash pipe is equipped with an independent intelligent host with a built-in FPGA chip, receiving and processing the pressure signals collected by the sensors in real time at a high-frequency sampling frequency of 100Hz, ensuring the timeliness and accuracy of the pressure data.

[0042] The different operating conditions cover the entire operating cycle of the ash conveying system, including the start-up phase (pre-pressurizing the silo pump to 0.15MPa), the stable conveying phase (maintaining a Froude number of 1.25-1.5), the reduction phase (linearly reducing the gas volume according to the ash-to-gas ratio curve), and special operating conditions such as pipe blockage warning. Under each operating condition, pressure sensors continuously collect real-time pressure values ​​at the corresponding locations in the pipeline. The system obtains pressure gradient data by calculating the pressure difference (ΔP) between adjacent sensors. The pressure gradient data directly reflects the trend of resistance changes in ash flow within the pipeline. For example, the pressure gradient is gentle during stable conveying, while when ash agglomerates or locally deposits, the pressure difference between adjacent sensors will increase abnormally, providing a direct basis for subsequent judgment of ash flow status and triggering of gas replenishment or control mechanisms.

[0043] By acquiring pressure and calculating gradients under different operating conditions using preset sensors, the system can monitor the dynamic pressure distribution in the ash conveying pipeline in real time. This provides real and continuous pressure gradient data support for the verification and correction of dynamic ash material characteristic maps (such as the judgment of the deviation between measured pressure loss and estimated pressure loss) and the condition adaptation of the dual-constraint optimization algorithm, ensuring that subsequent gas volume optimization and control can accurately respond to the actual flow state of ash material in the pipeline.

[0044] In some embodiments, it also includes: In response to the startup phase, the fluidizing gas flow rate is set to the rated value.

[0045] The start-up phase, as the initial stage of the ash conveying process, involves ash materials in the silo pump in a relatively static or accumulated state. Insufficient fluidization at this time can easily lead to ash material clumping and poor flowability, resulting in blockage at the pump outlet or the beginning of the pipeline. The rated value is the fluidizing gas volume benchmark value preset by the system based on the silo pump design parameters, ash material characteristics, and anti-blocking requirements. In actual operation, this is specifically manifested as the fluidizing gas volume being set to 120% of the design value. This setting is higher than the gas volume during the stable operation phase, aiming to ensure sufficient fluidization of the ash material by enhancing airflow disturbance.

[0046] From a hardware perspective, the system adds an independent fluidizing gas valve assembly (DN40) to each silo pump, coupled with a fluidizing chamber cone angle optimized to 60°±2°. This provides structural assurance for the stable output and uniform action of the rated fluidizing gas volume, enabling the airflow to penetrate the ash layer more evenly, breaking down the agglomeration forces between particles, and transforming the ash into a fluidized state. This ensures that the ash has good flowability to enter the ash conveying pipeline. Simultaneously, the setting of this rated fluidizing gas volume works synergistically with the control strategy of "pre-pressurizing the silo pump to 0.15MPa" during the startup phase. Through the dual guarantee of pressure and gas volume, this lays the foundation for achieving the Froude number (≥1.25) in the subsequent stable conveying phase. It prevents the risk of pipe blockage due to insufficient fluidization from the start-up stage, ensuring a smooth transition of the ash conveying system from standstill to operation.
