Description

Technical Field

[0001] The present application relates to the technical field of smelting, and in particular to a method, device, electronic equipment and storage medium for zero emission control of waste gas. Background Art

[0002] With the development of industry, the number of smelting plants such as steel and iron smelting is increasing day by day, and the number of corresponding production lines and production equipment is also increasing. During the production process, certain dust removal treatments will be carried out, and then a large amount of hot waste flue gas and dust-containing gas will be generated.

[0003] In the related technology, hot waste flue gas, dusty gas, etc. are directly discharged into the atmosphere after being dusted by certain dust removal equipment. However, even after being processed by the dust removal equipment, a certain amount of smoke and dust are still contained in them. When a large amount of waste gas is directly discharged into the atmosphere, the amount of particulate matter contained is also very large. Therefore, how to recycle the waste gas to reduce waste gas emissions has become an urgent problem to be solved. Summary of the invention

[0004] In order to recycle waste gas to achieve green production, the present application provides a waste gas zero emission control method, device, electronic equipment and storage medium.

[0005] In the first aspect, the present application provides a method for controlling zero emission of exhaust gas using the following technical solution: A method for controlling zero emission of exhaust gas, comprising: Get exhaust gas demand request; determining a requirement type of the exhaust gas demand request based on the exhaust gas demand; If the exhaust gas demand request includes a temperature requirement, controlling the first exhaust gas supply; if the exhaust gas demand request does not include a requirement, controlling the second exhaust gas supply; Before controlling the first exhaust gas supply or the second exhaust gas supply, the method further includes: Get dust concentration value; Determine whether the dust concentration value is greater than a dust concentration threshold value based on the dust concentration value; If the dust concentration value is greater than the dust concentration threshold, the dust removal module is controlled to operate to perform secondary dust removal; Among them, the exhaust gas storage module is used to receive the exhaust gas generated by each device and store the exhaust gas, which includes hot waste flue gas and dust-containing gas. The exhaust gas that does not enter the exhaust gas storage module is regarded as the first exhaust gas, and the exhaust gas that enters the exhaust gas storage module is regarded as the second exhaust gas.

[0006] By adopting the above technical solution, it is possible to intelligently judge the demand type according to the received exhaust gas demand request, and control the first exhaust gas supply or the second exhaust gas supply accordingly. This precise matching capability ensures the real-time correspondence between exhaust gas supply and demand, and improves the efficiency and accuracy of exhaust gas treatment. By using the exhaust gas that has not entered the exhaust gas storage module as the first exhaust gas, this part of the exhaust gas can be directly supplied to the equipment in need, reducing the transfer and storage links of the exhaust gas and improving the utilization efficiency of the exhaust gas. At the same time, the second exhaust gas entering the exhaust gas storage module can be processed more centrally and efficiently, thereby achieving the goal of energy conservation and emission reduction. By intelligently managing the supply and treatment of exhaust gas, the impact of exhaust gas generated during the production process on the environment is significantly reduced.

[0007] Optionally, the method further includes: obtaining an oxygen concentration requirement value based on the exhaust gas demand request; Obtaining a detection value of oxygen concentration of the exhaust gas; Determining whether the oxygen concentration detection value is greater than the oxygen concentration requirement value; If the oxygen concentration detection value is not greater than the oxygen concentration requirement value, calculating a first difference based on the oxygen concentration requirement value and the oxygen concentration detection value; calculating an average oxygen supply based on the first difference; A control signal is sent to the oxygen supply module based on the average oxygen supply.

[0008] By adopting the above technical solution, the oxygen concentration detection value of the exhaust gas can be intelligently obtained according to the oxygen concentration requirement value in the exhaust gas demand request, and by comparison, it can be determined whether the oxygen supply needs to be adjusted. Precise control ensures that the oxygen concentration in the exhaust gas can accurately meet specific needs, and improves the fineness and accuracy of exhaust gas treatment. Appropriate oxygen concentration helps the oxidation or reduction reaction of harmful substances in the exhaust gas, thereby accelerating the purification of the exhaust gas during the combustion process.

[0009] Optionally, the method further includes: Acquiring the pressure detection value of the exhaust gas storage module in real time; Determining whether the pressure detection value is greater than the first pressure threshold; If the pressure detection value is greater than the first pressure threshold, the air inlet of the exhaust gas storage module is closed.

[0010] By adopting the above technical solution, the pressure detection value of the exhaust gas storage module can be obtained in real time. The real-time monitoring capability provides data support for the precise control of the pressure of the exhaust gas storage module, ensuring the timeliness and accuracy of pressure management. When the pressure detection value exceeds the preset first pressure threshold, the electronic device will automatically control the closure of the air inlet of the exhaust gas storage module to prevent safety risks caused by excessive pressure. The intelligent adjustment mechanism effectively protects the structural integrity and operational stability of the exhaust gas storage module. Optionally, before closing the air inlet of the exhaust gas storage module, the method further includes: Determining whether the exhaust gas storage module is in a maximum gas output state; If the exhaust gas storage module is in a state of maximum gas output, the step of closing the air inlet of the exhaust gas storage module is not performed; Acquiring a corresponding air inlet adjustment value based on the pressure detection value; A control signal is sent based on the air intake adjustment value and the first exhaust gas supply is controlled.

[0011] By adopting the above technical solution, it is first determined whether the exhaust gas storage module is in the maximum gas output state. If so, the step of closing the air inlet will not be executed, ensuring that the air inlet will not be closed when the gas output demand is high, avoiding unnecessary air flow interruption, and ensuring the continuity of exhaust gas treatment. Based on the real-time pressure detection value, the electronic device can obtain the corresponding air inlet adjustment value, and send a control signal according to the adjustment value to dynamically adjust the first exhaust gas supply. This dynamic adjustment mechanism enables the size of the air inlet to be adjusted in real time according to the pressure change in the exhaust gas storage module, which not only ensures the smooth entry of exhaust gas, but also avoids the safety risks that may be caused by excessive pressure. By introducing the judgment of the maximum gas output state and the dynamic adjustment of the air inlet, the system can more flexibly respond to the exhaust gas treatment needs under different circumstances, and the intelligent adjustment method also helps to improve the stability of the system.

[0012] Optionally, the method further includes: Get the current time; Acquiring corresponding historical exhaust gas data based on the current time; Determining a change trend based on the historical exhaust gas data; If the historical exhaust gas data is on an upward trend, obtaining a preset time; Based on the preset time, the air inlet is controlled to gradually decrease to be closed; If the historical exhaust gas data is in a downward trend, determining in real time whether the pressure detection value is less than the second pressure threshold; If the pressure detection value is less than the second pressure threshold, the air outlet and the air inlet are controlled to be closed; The second pressure threshold is smaller than the first pressure threshold.

[0013] By adopting the above technical solution, the corresponding historical exhaust gas data is obtained based on the current time, and these data are used to determine the changing trend of exhaust gas emissions. The electronic equipment can make corresponding adjustments according to the rising or falling trend of exhaust gas emissions, so as to more actively manage the exhaust gas treatment process. When the historical exhaust gas data shows an upward trend, the electronic equipment will obtain the preset time and gradually reduce the air inlet until it is finally closed during this time period. The progressive closing method helps to make a smooth transition and avoid the impact on the exhaust gas treatment system caused by the sudden closure of the air inlet. Intelligently adjusting the switching status of the air inlet and outlet can optimize the exhaust gas treatment process according to actual conditions and improve the efficiency of exhaust gas treatment.

[0014] Optionally, before the air outlet and the air inlet are both closed, the method further includes: Determining whether the first exhaust gas supply quantity meets the demand quantity; If the first exhaust gas supply cannot meet the demand, the step of controlling the closing of the gas outlet is not performed; calculating a second difference based on the demand amount and the supply amount; acquiring a corresponding air outlet adjustment value based on the second difference; A control signal is sent based on the air outlet adjustment value.

[0015] By adopting the above technical solution, it is determined whether the first exhaust gas supply meets the demand, which helps to ensure the balance between supply and demand of exhaust gas treatment. If the supply cannot meet the demand, the step of closing the air outlet is not executed to avoid insufficient air supply. The corresponding air outlet adjustment value is obtained, and a control signal is sent according to the adjustment value to dynamically adjust the size of the air outlet. The dynamic adjustment mechanism enables the opening of the air outlet to be adjusted in real time according to the actual supply and demand situation, which not only ensures the smooth discharge of exhaust gas, but also avoids unnecessary energy waste. By real-time monitoring of supply and demand changes and rapid calculation of the air outlet adjustment value, the system can respond to exhaust gas treatment needs in a short time. Rapid response capability helps to improve the overall operating efficiency of the system and reduce performance losses caused by adjustment lags.

[0016] Optionally, when the exhaust gas demand request includes a temperature requirement, it also includes: Obtaining the working status of the heat recovery module; If the heat recovery module is in a necessary recovery state, after sending the control signal based on the outlet adjustment value, a path modification signal is sent to make the output second exhaust gas pass through the heat recovery module.

[0017] By adopting the above technical solution, when the exhaust gas demand request includes a temperature requirement and the heat recovery module is in a necessary recovery state, a path modification signal will be sent after adjusting the air outlet to allow the second exhaust gas to pass through the heat recovery module so that the second exhaust gas can undergo heat exchange to increase the temperature.

[0018] In the second aspect, the present application provides an exhaust gas zero emission control device that adopts the following technical solution: A first acquisition module, used for acquiring an exhaust gas demand request; A first judgment module, configured to judge the requirement type of the exhaust gas demand request based on the exhaust gas demand; if the exhaust gas demand request includes a temperature requirement, then the process is transferred to a first control module; if the exhaust gas demand request does not include a requirement, then the process is transferred to a second control module; The first control module is used to control the first exhaust gas supply; The second control module is used to control the second exhaust gas supply; A second acquisition module, used for acquiring a dust concentration value before controlling the first exhaust gas supply or the second exhaust gas supply; A second judgment module is used to judge whether the dust concentration value is greater than a dust concentration threshold value based on the dust concentration value; if the dust concentration value is greater than the dust concentration threshold value, the control is transferred to a third control module; The third control module is used to control the dust removal module to perform secondary dust removal; Among them, the exhaust gas storage module is used to receive the exhaust gas generated by each device and store the exhaust gas, which includes hot waste flue gas and dust-containing gas. The exhaust gas that does not enter the exhaust gas storage module is regarded as the first exhaust gas, and the exhaust gas that enters the exhaust gas storage module is regarded as the second exhaust gas.

[0028] The embodiment of the present application discloses a method for controlling zero emission of exhaust gas. The method for controlling zero emission of exhaust gas can be performed by an electronic device.

The terminal device can be a smart phone, a tablet computer, a desktop computer, etc., but is not limited thereto.

[0029] The present application embodiment discloses a method for controlling zero emission of exhaust gas. Figure 1 , a method for controlling zero emission of exhaust gas includes the following main processes: Step S100, obtaining an exhaust gas demand request; Step S200, determining the requirement type of the exhaust gas demand request based on the exhaust gas demand; if the exhaust gas demand request includes a temperature requirement, proceeding to step S300; if the exhaust gas demand request does not include a requirement, proceeding to step S500; Step S300, obtaining dust concentration value; Step S301, judging whether the dust concentration value is greater than the dust concentration threshold value; if the dust concentration value is greater than the dust concentration threshold value, proceeding to step S302; Step S302, controlling the dust removal module to operate to perform secondary dust removal; Step S400, controlling the supply of the first exhaust gas; Step S500, obtaining dust concentration value; Step S501, judging whether the dust concentration value is greater than the dust concentration threshold value; if the dust concentration value is greater than the dust concentration threshold value, proceeding to step S502; Step S502, controlling the dust removal module to operate to perform secondary dust removal; controlling the supply of the second exhaust gas; Among them, the exhaust gas storage module is used to receive the exhaust gas generated by each device and store the exhaust gas, which includes hot waste flue gas and dust-containing gas. The exhaust gas that does not enter the exhaust gas storage module is regarded as the first exhaust gas, and the exhaust gas that enters the exhaust gas storage module is regarded as the second exhaust gas.

[0030] The electronic device obtains the take-off demand request, and then determines the type of exhaust gas demand request based on the take-off request, that is, it needs to be supplied according to the demand situation. If the take-off demand request includes a temperature requirement, the electronic device controls the supply of the first exhaust gas; if the exhaust gas demand request does not include a temperature requirement, the electronic device controls the exhaust gas storage module to supply the second exhaust gas. Both the first exhaust gas and the second exhaust gas are exhaust gases. The first exhaust gas is the part of the collected exhaust gas that has not entered the exhaust gas storage module, and the second exhaust gas is the part that has entered the exhaust gas storage module for storage.

[0031] Before the electronic device controls the supply of the first exhaust gas or the second exhaust gas, the electronic device also needs to obtain the dust concentration value of the exhaust gas, and then the electronic device determines whether the dust concentration value is greater than the dust concentration threshold. The exhaust gas has been dust-removed when it is recycled. However, during recycling and storage, long-term accumulation will also cause dust accumulation, thereby mixing a certain amount of dust when the exhaust gas is supplied. Therefore, it is necessary to control the dust concentration of the supplied exhaust gas. If the dust concentration value is greater than the concentration threshold, the electronic device needs to control the dust removal module to perform secondary dust removal on the exhaust gas.

[0032] The sources of waste gas are all parts related to flue gas and dusty gas in the production process of steel mills, iron mills, rolling mills, etc., including but not limited to the waste gas generated by pelletizing workshops, sintering workshops, lime kiln workshops, and waste gas generated by dust removal of various equipment such as blast furnaces, sintering machines, chain grates, rotary kilns, converters, lime kilns, etc. The specific sources are not limited to the above equipment. The reuse of waste gas is to apply the waste gas to the equipment that needs to be burned. Since combustion requires oxygen in the air, the waste gas can be applied to equipment that can burn, such as blast furnaces, sintering machines and other equipment. The waste gas is directly introduced into the equipment that needs to be burned, eliminating the step of emitting the waste gas into the atmosphere, thereby reducing the amount of particulate matter contained in the waste gas emitted into the air, and realizing the recycling and reuse of waste gas to reduce emissions to the atmosphere and achieve green production.

[0033] As an optional implementation of the embodiment of the present application, the method further includes: obtaining an oxygen concentration requirement value based on an exhaust gas demand request; obtaining an oxygen concentration detection value of the exhaust gas; determining whether the oxygen concentration detection value is greater than the oxygen concentration requirement value; if the oxygen concentration detection value is not greater than the oxygen concentration requirement value, calculating a first difference based on the oxygen concentration requirement value and the oxygen concentration detection value; calculating an average oxygen supply based on the first difference; and sending a control signal to the oxygen supply module based on the average oxygen supply. The electronic device obtains the oxygen concentration requirement value based on the exhaust gas demand request, that is, when the combustion equipment is burning, a high oxygen content may be required to make the combustion more intense, so the electronic device obtains the oxygen concentration detection value of the exhaust gas, and then the electronic device determines whether the oxygen concentration detection value is greater than the oxygen concentration requirement value. If the oxygen concentration detection value is not greater than the oxygen concentration requirement value, the electronic device calculates a first difference based on the oxygen concentration requirement value and the oxygen concentration detection value, and then calculates the average oxygen supply based on the first difference, that is, calculates the oxygen content that needs to be supplemented. Then, the electronic device sends a control signal to the oxygen supply module based on the oxygen supply, so that the oxygen supply module supplies oxygen to the exhaust gas, thereby increasing the proportion of oxygen in the exhaust gas, thereby meeting the combustion demand.

[0034] As an optional implementation of an embodiment of the present application, the method also includes: acquiring a pressure detection value of the exhaust gas storage module in real time; determining whether the pressure detection value is greater than a first pressure threshold; and closing the air inlet of the exhaust gas storage module if the pressure detection value is greater than the first pressure threshold.

[0035] The electronic device obtains the pressure detection value of the waste gas storage module in real time, and then determines whether the pressure detection value is greater than the first pressure threshold, that is, determines whether the waste gas stored in the storage module is excessive. If the pressure detection value is greater than the first pressure threshold, the electronic device controls the air inlet of the waste gas storage module to close. Since the pressure detection value is too large, it means that the storage pressure of the waste gas storage module is too large at this time, and it is not appropriate to add waste gas to the storage module at this time, so the electronic device controls the air inlet of the waste gas storage module to close.

[0036] As an optional implementation of an embodiment of the present application, before closing the air inlet of the exhaust gas storage module, it also includes: judging whether the exhaust gas storage module is in a maximum air outlet state; if the exhaust gas storage module is in a maximum air outlet state, not executing the step of closing the air inlet of the exhaust gas storage module; obtaining a corresponding air inlet adjustment value based on the pressure detection value; sending a control signal based on the air inlet adjustment value and controlling the first exhaust gas supply.

[0037] Before the electronic device controls the air inlet to close, the electronic device determines whether the exhaust gas storage module is in the state of maximum air output. If the exhaust gas storage module is in the state of maximum air output, the electronic device does not perform the step of controlling the air inlet to close, but obtains the air inlet adjustment value based on the pressure detection value, and the electronic device sends a control signal based on the air inlet adjustment value, that is, the electronic device controls the opening change of the air inlet to reduce the amount of exhaust gas entering the exhaust gas storage module, which can avoid the rapid drop of exhaust gas in the exhaust gas storage module, so as to better control the amount of exhaust gas in the exhaust gas storage module. At the same time, the first exhaust gas supply is controlled to adjust the balance of supply, demand and storage.

[0038] As an optional implementation scheme of the embodiment of the present application, the method also includes: obtaining the current time; obtaining the corresponding historical exhaust gas data based on the current time; judging the change trend based on the historical exhaust gas data; if the historical exhaust gas data is on an upward trend, obtaining a preset time; controlling the air inlet to gradually decrease to closed based on the preset time; if the historical exhaust gas data is on a downward trend, judging in real time whether the pressure detection value is less than a second pressure threshold; if the pressure detection value is less than the second pressure threshold, controlling both the air outlet and the air inlet to be closed; wherein the second pressure threshold is less than the first pressure threshold.

[0039] The electronic device obtains the current time, and obtains the corresponding historical exhaust gas data based on the current time, and then determines the change trend based on the historical exhaust gas data. If the historical exhaust gas data is in an upward trend, it indicates that the current situation is that supply exceeds demand, so the electronic device obtains the preset time, and controls the air inlet to gradually decrease to close based on the preset time. The amount of exhaust gas is increasing. If the exhaust gas storage module does not close the air inlet, it will not undertake the task of storing more exhaust gas, so the air inlet is gradually closed at this time, and the exhaust gas is directly supplied, that is, all the first exhaust gas is used for supply. Even if the supply of the first exhaust gas is greater than the demand, this method is adopted to achieve rapid consumption. If the historical exhaust gas data is in a downward trend, the electronic device determines in real time whether the pressure detection value is less than the second pressure threshold. If the pressure detection value is less than the second pressure threshold, the electronic device controls the exhaust gas storage module to close both the outlet and the inlet. At this time, it can ensure that the flying storage module stores a certain amount of exhaust gas for subsequent use, and can also directly supply the first exhaust gas to ensure that the demand can be met.

[0040] As an optional implementation manner of the embodiment of the present application, before controlling the air outlet and the air inlet to be closed, it also includes: judging whether the first exhaust gas supply quantity meets the demand quantity; if the first exhaust gas supply quantity cannot meet the demand quantity, not executing the step of controlling the air outlet to be closed; calculating the second difference based on the demand quantity and the supply quantity; obtaining the corresponding air outlet adjustment value based on the second difference; and sending a control signal based on the air outlet adjustment value.

[0041] Before controlling the air inlet and the air outlet to be closed, the electronic device determines whether the first exhaust gas supply meets the demand. If the first exhaust gas supply does not meet the demand, it indicates that the supply is less than the demand at this time. Therefore, the electronic device does not execute the step of controlling the air outlet to be closed, but calculates the second difference between the demand and the supply, and obtains the corresponding air outlet adjustment value based on the second difference. The electronic device outputs a control signal based on the air outlet adjustment value to adjust the opening of the air outlet, that is, to control the second exhaust gas supply of the exhaust gas storage module, so that the combined amount of the first exhaust gas and the second exhaust gas can meet the demand.

[0042] As an optional implementation of an embodiment of the present application, when the exhaust gas demand request includes a temperature requirement, it also includes: obtaining the working status of the heat recovery module; if the heat recovery module is in a necessary recovery state, then after sending a control signal based on the outlet adjustment value, a path modification signal is sent to allow the output first exhaust gas to pass through the heat recovery module.

[0043] When the exhaust gas demand request includes a temperature requirement, the working status of the heat recovery module is obtained at this time. If the heat recovery module is in a necessary recovery state, after the electronic device sends a control signal based on the outlet adjustment value, a path modification signal is sent to allow the output second exhaust gas to pass through the heat recovery module to achieve a certain degree of heating.

[0044] The heat recovery module is used to recover the heat emitted by the combustion equipment. If the heat recovery module is in a non-essential recovery state, it means that the combustion equipment may not have heat dissipation or low heat dissipation at this time, and does not have the conditions for heat recovery. Therefore, it is meaningless for the second exhaust gas to pass through the heat recovery module at this time. Therefore, it is necessary to determine that the heat recovery module is in a necessary recovery state, and the second exhaust gas can achieve a certain degree of temperature rise after passing through the heat recovery module.
