Description

Technical Field

[0001] This invention relates to the field of automatic control technology, and more specifically, to a method and apparatus for ultra-low emission management and control of flue gas applicable to the operation of electric furnaces. Background Technology

[0002] In the industrial production process of electric arc furnace smelting, high-temperature flue gas rich in harmful gases such as silica dust and sulfur dioxide is typically generated. To prevent further deterioration of air pollution, the flue gas needs to be treated to meet ultra-low emission requirements. Generally, electric arc furnaces are equipped with three major environmental protection devices: denitrification, dust removal, and desulfurization, to remove nitrates, dust, and sulfides respectively. However, in actual operation, the working state of the electric arc furnace cannot remain stable but fluctuates, resulting in fluctuations in the total amount of flue gas produced, necessitating adjustments to the operating parameters of the environmental protection equipment. Currently, however, environmental protection equipment typically only adjusts its operating parameters when it detects that the content of harmful gases in the flue gas passing through the equipment exceeds the standard, resulting in a lag. This means that the flue gas emission process cannot maintain ultra-low emissions throughout, leading to ineffective pollution control of the emitted flue gas. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a method and apparatus for ultra-low emission management and control of flue gas applicable to the operation of electric furnaces.

[0030] Figure 3 This is a schematic diagram of the structure of an electronic device provided by the present invention. Detailed Implementation

[0031] See Figure 1 , Figure 1 This is a schematic flowchart illustrating a method for ultra-low emission management and control of flue gas during electric furnace operation, provided in an embodiment of this application. In this embodiment, the method includes:

[0032] S101. Obtain historical operating parameter data, which includes historical electric furnace operating parameter data and historical environmental protection equipment operating parameter data.

[0033] The entity executing this application may be a cloud server.

[0034] In this embodiment, the electric furnace and environmental protection equipment are considered as a single electric furnace system. During operation, the electric furnace system generates historical operating parameter data. This historical operating parameter data includes historical operating data of the electric furnace and historical operating data of the environmental protection equipment. To determine the delay processing status of the electric furnace system under current conditions, the historical operating parameter data will be acquired first.

[0035] S102. Based on the historical operating parameter data, calculate the flue gas delay treatment time of each environmental protection device relative to the electric furnace.

[0036] In this embodiment, based on historical operating parameter data, the timing of fluctuations in the electric furnace parameters and the time required for each environmental protection device to adjust its parameters to improve flue gas treatment efficiency after the electric furnace parameters fluctuate can be analyzed and determined. By analyzing historical operating parameter data, the time required for each environmental protection device to adjust its parameters to adapt to changes in flue gas volume after the electric furnace parameters fluctuate can be calculated, i.e., the flue gas delayed treatment time.

[0037] In one possible implementation, step S102 includes:

[0038] Calculate the time delay between the change in the historical operating parameter data of the electric furnace and the change in the operating parameter data of the historical environmental protection equipment for each environmental protection device;

[0039] The processing time of each of the environmental protection devices is obtained, and the difference between the delay time and the processing time is calculated to obtain the flue gas delay processing time.

[0040] In this embodiment, the electric furnace does not fluctuate constantly; it operates smoothly most of the time. This allows for easy identification of the location of fluctuations using historical data, enabling the determination of the delay between changes in historical furnace operating parameters and changes in historical environmental protection equipment operating parameters. Considering that historical data shows environmental protection equipment parameters are only adjusted after exceeding the limit for harmful gas content at the equipment outlet, to achieve the proactive early adjustment effect of this application, parameter adjustment should be completed at the moment the flue gas enters the equipment. Therefore, the equipment processing time required for conventional environmental protection equipment treatment needs to be subtracted to finally obtain the flue gas delayed treatment time.

[0041] S103. When the real-time electric furnace operating parameter data changes, determine the environmental protection equipment parameter adjustment value, and adjust each of the environmental protection equipment based on the flue gas delay treatment time and the environmental protection equipment parameter adjustment value.

[0042] In this embodiment, after calculating and determining the flue gas delay treatment time, it is not necessary to wait until the content of harmful gases in the flue gas discharged by the environmental protection equipment is still high before making passive adjustments, which would result in an interval time that cannot guarantee ultra-low emissions. Instead, the parameter values ​​that the environmental protection equipment needs to be adjusted can be determined in advance when the real-time electric furnace operating parameter data changes, and the time required to adjust the values ​​can be actively estimated based on the flue gas delay treatment time, so as to ensure that ultra-low emissions are achieved throughout the entire production process.

[0043] In one possible implementation, determining the environmental protection equipment parameter adjustment value when the real-time electric furnace operating parameter data changes includes:

[0044] When the real-time operating parameter data of the electric furnace changes, obtain the parameter prediction model corresponding to each of the environmental protection devices.

[0045] The real-time electric furnace operating parameter data is imported into the parameter prediction model to obtain the environmental protection equipment parameter prediction value;

[0046] The adjustment value of the environmental protection equipment parameters is calculated based on the estimated value of the environmental protection equipment parameters and the current environmental protection equipment parameters.

[0047] In this embodiment, parameter prediction models can be pre-trained for the electric furnace and each environmental protection device. These models will be used to predict the parameter values ​​required for the environmental protection devices to achieve ultra-low emissions based on the real-time parameter values ​​of the electric furnace. Specifically, this parameter prediction model can employ a CNN neural network convolutional model, trained using historical data as the training set. After obtaining the predicted parameter values ​​for the environmental protection devices, combined with the current parameters, the necessary adjustment values ​​for the environmental protection device parameters can be calculated.

[0048] In one possible implementation, the step of adjusting each of the environmental protection devices based on the flue gas delay treatment time and the environmental protection device parameter adjustment value includes:

[0049] The effective duration of the environmental protection equipment parameter adjustment values ​​is determined based on a preset mapping table;

[0050] The actual delay processing time is obtained by calculating the difference between the flue gas delay processing time and the effective time.

[0051] After the actual delay processing time, the environmental protection equipment is adjusted based on the environmental protection equipment parameter adjustment value.

[0052] In this embodiment, a mapping table is pre-set, which sets the mapping relationship between the environmental protection equipment parameter adjustment values ​​determined by previous simulation tests and the effective time elapsed after the actual performance change of the equipment to meet the requirements. To ensure that the performance of the environmental protection equipment has been adjusted to meet the standards when the flue gas enters the equipment, the parameters should be adjusted in advance of the effective time, that is, the parameters of the environmental protection equipment should be adjusted after the actual delay processing time has elapsed since the real-time parameters of the electric furnace change.

[0053] In one possible implementation, the method further includes:

[0054] When the cumulative duration of a single instance where the current environmental protection equipment parameters exceed the preset critical parameter value exceeds the preset duration, an adjustment command is sent to the electric furnace to adjust the current electric furnace parameters, thereby reducing the capacity of the electric furnace.

[0055] In this embodiment, considering that the environmental protection equipment may operate under load for a long time in order to ensure ultra-low emissions, and in order to ensure the service life of the environmental protection equipment, if the current environmental protection equipment parameters exceed the critical parameter values ​​for a long time, an adjustment command will be sent to the electric furnace to temporarily reduce the capacity of the electric furnace by adjusting the electric furnace parameters, thereby reducing the amount of flue gas generated and reducing the load on the environmental protection equipment.
