Description

Technical Field

[0001] This application relates to the technical field of environmental engineering, and in particular to a method, apparatus, equipment and computer storage medium for the treatment and control of acid mist exhaust gas. Background Technology

[0002] Acid mist exhaust contains acid mist particles that are very small, smaller than water mist particles but with higher humidity than smoke particles. The particle size is between 0.1 μm and 10 μm. It is a substance between smoke and water mist, and its direct emission into the air can easily cause pollution.

[0003] In related technologies, the main method for purifying acid mist exhaust gas is the spray circulation method, which is a relatively economical and simple method for exhaust gas treatment. However, during the neutralization treatment of acid mist exhaust gas using a spray tower, there may be insufficient neutralization or waste due to the excessive use of alkali solution, and precise control over the spray neutralization process is not possible. Summary of the Invention

[0004] In order to achieve precise control over the spray treatment process, this application provides an acid mist exhaust gas treatment control method, device, equipment, and computer storage medium.

[0005] Firstly, the acid mist exhaust gas treatment and control method provided in this application adopts the following technical solution: A method for treating and controlling acid mist exhaust gas includes: Real-time acquisition of the current pH value of the first acid mist exhaust gas at the air inlet; The corresponding first spraying volume is obtained based on the current pH value of the first acid mist exhaust gas. Get the current spray volume; The current spray volume is adjusted based on the first spray volume; Obtain the current pH value of the second acid mist exhaust gas; Determine whether the pH value of the current second acid mist exhaust gas meets the emission standards; If the pH value of the current second acid mist exhaust gas does not meet the emission standards, a circulation processing signal will be output.

[0006] By adopting the above technical solution, the current pH value of the first acid mist exhaust gas at the inlet is obtained in real time, and the corresponding first spray volume is determined based on this. This allows for rapid assessment of the acidity of the acid mist exhaust gas entering the treatment system, and the corresponding amount of alkaline solution sprayed can be quickly determined accordingly. This enables on-demand treatment, avoiding the use of excessive or insufficient alkaline solution. Automated processing allows for rapid and effective real-time adjustments, improving treatment efficiency. Real-time monitoring, dynamic adjustment, and feedback control achieve precision and high efficiency in acid mist exhaust gas treatment. The current pH value of the second acid mist exhaust gas is obtained, and its compliance with emission standards is determined. Real-time monitoring of the treated exhaust gas provides a direct understanding of the neutralization effect of the acid mist exhaust gas, ensuring that the treated gas meets environmental emission requirements and preventing the emission of excessive exhaust gas due to insufficient treatment. When the current pH value of the second acid mist exhaust gas does not meet the emission standards, the electronic equipment outputs a cyclic processing signal, i.e., the excessive exhaust gas is circulated for treatment, thereby making it compliant with the standards. This forms a closed-loop control mechanism.

[0007] Optionally, before correcting the current spray volume based on the first spray volume, the method further includes: The pH value of the third acid mist exhaust gas is obtained from the previous moment based on the current moment; Calculate the first difference between the current pH value of the first acid mist exhaust gas and the pH value of the third acid mist exhaust gas; Take the absolute value of the first difference; Determine whether the absolute value is greater than the change threshold; If the absolute value is greater than the change threshold, then it is determined whether the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas; If the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas, then when performing the correction of the current spraying amount based on the first spraying amount, a preset time is obtained; The current spraying volume is gradually changed to the first spraying volume based on the preset time.

[0008] By adopting the above technical solution, before correcting the current spray volume based on the first spray volume, the electronic device calculates the difference, takes the absolute value of the difference, and determines whether the absolute value is greater than the change threshold. At this point, it checks whether the pH value of the acid mist exhaust gas has changed significantly. If the absolute value is greater than the change threshold, the change is large, so further judgment is made: whether the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas, i.e., whether the acidity has decreased significantly. If the pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas, the electronic device adopts a gradual correction method when correcting the current spray volume based on the first spray volume. That is, it gradually corrects to the first spray volume within a preset time, rather than making an instantaneous correction. This can avoid insufficient spray volume due to fluctuations in the pH value of the acid mist exhaust gas, that is, it can better cope with fluctuations and thus avoid incomplete neutralization.

[0009] Optionally, when gradually changing the current spray volume to the first spray volume based on the preset time, the method further includes: Real-time determination of whether the pH value of the current first acid mist exhaust gas changes to a decrease; If the pH value of the current first acid mist exhaust gas changes to a decrease, then calculate the second difference between the pH value of the third acid mist exhaust gas and the pH value of the current first acid mist exhaust gas; Determine whether the second difference is greater than the first threshold; The first threshold is equal to the absolute value divided by three; If the second difference is greater than the first threshold, then the spray volume at the previous moment is obtained based on the first spray volume and the current spray volume is corrected, and the obtained spray volume is used as the second spray volume; The current spray volume is adjusted based on the second spray volume.

[0010] By adopting the above technical solution, during the gradual change of spray volume, the pH value of the first acid mist exhaust gas is monitored in real time to see if it decreases. If the pH value of the first acid mist exhaust gas decreases, the electronic device calculates a second difference and then determines whether the second difference is greater than a first threshold, i.e., whether the change is too large. The first threshold is equal to the absolute value divided by three. If the second difference is greater than the first threshold, the electronic device controls the spray volume to return to the second spray volume. Real-time sensing of the pH value change of the acid mist exhaust gas during exhaust gas treatment achieves true dynamic feedback control, improving the flexibility and accuracy of control. In this case, the decrease in the pH value of the acid mist exhaust gas exceeds one-third of the absolute value, indicating that the previous large fluctuations may be abnormal. Therefore, the spray volume is directly restored to the second spray volume to ensure sufficient spray volume to neutralize the acid mist exhaust gas. Furthermore, the first threshold is dynamically changing and related to previous detection data, allowing for better adjustment based on actual conditions. This ensures sufficient spray volume for neutralization while minimizing waste.

[0011] Optionally, before correcting the current spray volume based on the second spray volume, the method further includes: Based on the preset time, the current spray volume is adjusted to start timing and a first timing time is obtained; When the second difference is greater than the first threshold, the first timing period stops. The first duration is obtained based on the first timing period; Determine whether the first duration is greater than the second threshold; The second threshold is equal to two-thirds of the preset time; If the first duration is greater than the second threshold, then the step of correcting the current spray volume based on the second spray volume is stopped. The process then transitions to the step of acquiring the current pH value of the first acid mist exhaust gas at the air inlet in real time. If the first duration is not greater than the second threshold, then the step of correcting the current spray volume based on the second spray volume continues.

[0012] By adopting the above technical solution, before the correction based on the second spray volume, the electronic device starts timing based on a preset time to correct the current spray volume and obtains a first timing time. The first timing time starts from the time when the current spray volume gradually changes to the initial time of the first spray volume. Then, when the second difference is greater than the first threshold, the first timing time stops. After that, the electronic device obtains a first duration based on the first timing time. The electronic device judges whether the first duration is greater than the second threshold. The second threshold is equal to two-thirds of the preset time. That is, when the electronic device judges that the second difference is greater than the first threshold, whether the actual time taken for correction based on the preset time has exceeded two-thirds of the preset time. If the first duration is greater than the second threshold, the electronic device stops executing the step of correcting the current spray volume based on the second spray volume. At this time, a lot of time has been spent adjusting the spray volume, so it does not instantly restore to the first spray volume. Instead, it switches to the step of real-time acquisition of the current first acid mist exhaust gas pH value at the air inlet, that is, it switches to the step of real-time control, avoiding more waste. At the same time, it can also perform real-time control based on real-time detection, thereby meeting the need for neutralizing acid mist exhaust gas. Furthermore, a time limit is introduced to prevent premature exit from disrupting the strategy, and to prevent premature exit from wasting resources or over-processing.

[0013] Optionally, after the output loop processing signal, the following may also be included: The first increment is obtained based on the current pH value of the second acid mist exhaust gas. The current spraying volume is adjusted based on the first increment.

[0014] By adopting the above technical solution, after outputting the circulation processing signal, since the acid mist exhaust gas has been determined to be non-compliant with emission standards, it is necessary to circulate the acid mist exhaust gas that has already been treated once. The electronic equipment obtains the corresponding first increment based on the current pH value of the second acid mist exhaust gas. The first increment is an additional spray volume added while meeting the normal treatment process. Then, the electronic equipment adjusts the current spray volume based on the first increment. That is, by increasing the first increment, the neutralization requirements of the circulated acid mist exhaust gas are met. At the same time, because it is an additional addition, it will not cause insufficient spray volume for the neutralization of the normally treated acid mist exhaust gas. The circulation processing method also ensures that the final emitted acid mist exhaust gas meets emission standards, and the increase in spray volume is based on actual needs, which can reduce unnecessary waste.

[0015] Optionally, before correcting the current spray volume based on the first increment, the method further includes: Determine whether the step of gradually changing the current spray volume to the first spray volume based on the preset time is being performed; If the step of gradually changing the current spraying amount to the first spraying amount based on the preset time is being performed, the total surplus is calculated based on the preset time, the current spraying amount, and the first spraying amount. The total supplementary amount is calculated based on the preset time and the first increment; Determine whether the total surplus is greater than or equal to the total replenishment; If the total surplus is greater than or equal to the total replenishment, then the step of correcting the current spraying amount based on the first increment is stopped. If the total surplus is not greater than the total replenishment, then the step of correcting the current spraying amount based on the first increment continues.

[0016] By adopting the above technical solution, before the electronic device adjusts the current spray volume based on the first increment, the electronic device determines whether it is currently executing the step of gradually changing the current spray volume to the first spray volume based on a preset time. If it is, the electronic device calculates the surplus amount based on the preset time, the current spray volume, and the first spray volume. Then, the electronic device calculates the supplementary amount based on the preset time and the first increment. It determines whether the surplus amount is greater than the supplementary amount. If the surplus amount is greater than the supplementary amount, the electronic device does not execute the step of adjusting the current spray volume based on the first increment; if the surplus amount is not greater than the supplementary amount, it continues to execute. This method can utilize the surplus spray volume during the gradual reduction of the spray volume in the normal treatment process to treat the acid mist waste gas that needs to be circulated, realizing the utilization of the surplus spray volume. At the same time, the circulation treatment is less frequent, which can also reduce the impact on the normal treatment process. Furthermore, even if the surplus amount is greater than the supplementary amount, it can still cope with the situation where the pH value of the acid mist waste gas rises in the normal process. When faced with multiple spray volume adjustment requirements, instead of simply adding them up or executing them directly, we first assess whether the existing adjustments can meet the new requirements, achieve coordinated optimization between control objectives, avoid repeated or excessive adjustments, improve the rationality of the overall control strategy, and achieve the improvement from coarse adjustment to fine coordination.

[0017] Optionally, after stopping the step of correcting the current spray volume based on the first increment, the method further includes: Obtain the increase in pH value of the current second acid mist exhaust gas after one cycle of treatment; Calculate the reciprocal of the increase value and use the reciprocal as a proportionality coefficient; The second increment is obtained by multiplying the proportionality coefficient by the first increment; The current spray volume is corrected based on the second increment, and a multi-cycle processing signal is output.

[0018] By adopting the above technical solution, after stopping the step of correcting the current spray volume based on the first increment, the electronic device acquires the increase in the pH value of the current second acid mist exhaust gas after one cycle of processing. It then calculates the reciprocal of this increase and uses it as a proportionality coefficient. This coefficient is multiplied by the first increment to obtain the second increment. The current spray volume is then corrected based on this second increment, and multiple cycle processing signals are output. Calculating the proportionality coefficient based on the increase value allows for dynamic calculation of the second increment according to actual conditions, ensuring that the second increment better meets actual needs. Since one cycle of processing has already been completed, the preset time correction process may have been finished or largely completed. To better meet the needs of subsequent cycles, a second increment is required. This also allows for better handling of future unforeseen anomalies, minimizing waste while meeting current requirements and addressing potential issues.

[0019] Secondly, the acid mist exhaust gas treatment and control device provided in this application adopts the following technical solution: An acid mist exhaust gas treatment and control device, comprising: The first acquisition module is used to acquire the current pH value of the first acid mist exhaust gas at the air inlet in real time. The second acquisition module is used to acquire the corresponding first spraying amount based on the current pH value of the first acid mist exhaust gas. The third acquisition module is used to acquire the current spray volume; The first correction module is used to correct the current spraying volume based on the first spraying volume; The fourth acquisition module is used to acquire the current pH value of the second acid mist exhaust gas; The judgment module is used to transfer the signal to the output module if the pH value of the current second acid mist exhaust gas does not meet the emission standards. The output module is used to output a cyclic processing signal.

[0020] Thirdly, the electronic device provided in this application adopts the following technical solution: An electronic device includes a processor coupled to a memory; the processor is configured to execute a computer program stored in the memory such that the electronic device performs the method as described in the first aspect.

[0021] Fourthly, the computer-readable storage medium provided in this application adopts the following technical solution: A computer-readable storage medium includes a computer program or instructions that, when executed on a computer, cause the computer to perform the method as described in the first aspect.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The system acquires the current pH value of the first acid mist exhaust gas at the inlet in real time and determines the corresponding initial spray volume accordingly. This allows for rapid assessment of the acidity of the exhaust gas entering the treatment system and quickly calculates the required amount of alkaline solution to be sprayed, enabling on-demand treatment and avoiding excessive or insufficient use of alkaline solution. Automated processing allows for rapid and effective real-time adjustments, improving treatment efficiency. Real-time monitoring, dynamic adjustment, and feedback control achieve precise and efficient acid mist exhaust gas treatment. The system also acquires the current pH value of the second acid mist exhaust gas and determines whether it meets emission standards. Real-time monitoring of the treated exhaust gas provides a direct understanding of the neutralization effect, ensuring that the treated gas meets environmental emission requirements and preventing the emission of excessive exhaust gas due to insufficient treatment. When the current pH value of the second acid mist exhaust gas does not meet emission standards, the electronic equipment outputs a cyclic processing signal, recirculating the excessive exhaust gas to bring it into compliance. This forms a closed-loop control mechanism. Attached Figure Description

[0029] This application discloses a method for controlling acid mist exhaust gas treatment. This method can be executed by an electronic device. The electronic device can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet computer, desktop computer, etc., but is not limited to these.

[0030] This application discloses a method for controlling acid mist exhaust gas treatment. (Refer to...) Figure 1 The main process of an acid mist exhaust gas treatment and control method is described as follows (S100~S700): Step S100: Obtain the current pH value of the first acid mist exhaust gas at the air inlet in real time; Step S200: Obtain the corresponding first spray volume based on the current pH value of the first acid mist exhaust gas; Step S300: Obtain the current spray volume; Step S400: Adjust the current spray volume based on the first spray volume; Step S500: Obtain the current pH value of the second acid mist exhaust gas at the outlet; Step S600: Determine whether the pH value of the current second acid mist exhaust gas meets the emission standards; if the pH value of the current second acid mist exhaust gas does not meet the emission standards, proceed to step S700. Step S700: Output the loop processing signal.

[0031] The electronic device acquires the current pH value of the first acid mist exhaust gas exiting the inlet in real time. Based on this pH value, it determines the corresponding first spray volume, using an alkaline solution to neutralize the acid mist exhaust gas. This first spray volume is a pre-set value, sufficient to meet the neutralization requirements of the current acid mist exhaust gas. The electronic device then acquires the current spray volume and adjusts it based on the first spray volume to ensure it meets the neutralization requirements. Next, the electronic device acquires the current pH value of the second acid mist exhaust gas at the outlet, detecting the result after neutralization. It then determines whether the pH value of the second acid mist exhaust gas meets emission standards. If it does not meet the standards, the electronic device outputs a recirculation signal, recirculating the acid mist exhaust gas after one normal treatment to reduce its acidity and ensure it meets emission standards, preventing the release of acid mist exhaust gas into the environment due to insufficient neutralization.

[0032] As an optional implementation of this application, before correcting the current spray volume based on the first spray volume, the method further includes: obtaining the pH value of the third acid mist exhaust gas at the previous time based on the current time; calculating the first difference between the current pH value of the first acid mist exhaust gas and the pH value of the third acid mist exhaust gas; taking the absolute value of the first difference; determining whether the absolute value is greater than a change threshold; if the absolute value is greater than the change threshold, determining whether the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas; if the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas, obtaining a preset time when correcting the current spray volume based on the first spray volume; and gradually changing the current spray volume to the first spray volume based on the preset time.

[0033] Before the electronic device adjusts the current spray volume based on the first spray volume, it acquires the pH value of the third acid mist exhaust gas from the previous moment. Then, it calculates the first difference between the current pH value of the first acid mist exhaust gas and the pH value of the third acid mist exhaust gas. The absolute value of this first difference is taken, and it is then determined whether the absolute value is greater than a change threshold, i.e., whether the pH change of the acid mist exhaust gas is too large. If the absolute value is greater than the change threshold, the electronic device determines whether the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas, i.e., whether the acidity has decreased significantly. If the current pH value of the first acid mist exhaust gas is greater than the pH value of the third acid mist exhaust gas, the electronic device, when adjusting the current spray volume based on the first spray volume, acquires a preset time. Then, based on the preset time, it gradually changes the current spray volume to the first spray volume. That is, within the preset time, the spray volume is gradually changed until it is adjusted to the first spray volume. Transforming instantaneous adjustment into adjustment within a preset time allows for better handling of future pH decreases or fluctuations in the acid mist exhaust gas, and more effectively neutralizes the acid mist exhaust gas.

[0034] As an optional implementation of this application, when the current spraying amount is gradually changed to the first spraying amount based on a preset time, the method further includes: determining in real time whether the current pH value of the first acid mist exhaust gas changes to a decreasing value; if the current pH value of the first acid mist exhaust gas changes to a decreasing value, calculating a second difference between the pH value of the third acid mist exhaust gas and the current pH value of the first acid mist exhaust gas; determining whether the second difference is greater than a first threshold; the first threshold is equal to the absolute value divided by three; if the second difference is greater than the first threshold, obtaining the spraying amount at the previous moment based on the first spraying amount to correct the current spraying amount, and using the obtained spraying amount as the second spraying amount; and correcting the current spraying amount based on the second spraying amount.

[0035] When the current spray volume is changed to the first spray volume based on a preset time, that is, during the adjustment process, the electronic device determines in real time whether the current pH value of the first acid mist exhaust gas changes to a decrease, that is, whether the acidity of the acid mist exhaust gas at the air inlet increases. If the current pH value of the first acid mist exhaust gas changes to a decrease, the electronic device calculates the second difference between the pH value of the third acid mist exhaust gas and the current pH value of the first acid mist exhaust gas. The second difference is a positive number. Then the electronic device determines whether the second difference is greater than the first threshold. The first threshold is equal to the absolute value divided by three, that is, the first threshold is equal to one-third of the absolute value. If the second difference is greater than the first threshold, the electronic device obtains the spray volume at the moment before the current spray volume is corrected based on the first spray volume, that is, obtains the spray volume at the moment before the correction is made, which is the initial spray volume, and uses the obtained spray volume as the second spray volume. Then the current spray volume is corrected based on the second spray volume. After the pH value of the acid mist exhaust gas rises, i.e., when the second difference is greater than the first threshold, the initial spraying volume is restored to cope with the pH value change of the acid mist exhaust gas. This is because the previous large change may be caused by abnormal conditions or short-term sudden changes, so the spraying volume is restored at this time to cope with it and avoid the acid mist exhaust gas not being fully neutralized.

[0036] As an optional implementation of this application, before correcting the current spray volume based on the second spray volume, the method further includes: starting a timer based on a preset time to correct the current spray volume and obtaining a first timer; stopping the first timer when the second difference is greater than a first threshold; obtaining a first duration based on the first timer; determining whether the first duration is greater than a second threshold; the second threshold is equal to two-thirds of the preset time; if the first duration is greater than the second threshold, stopping the step of correcting the current spray volume based on the second spray volume; and switching to the step of obtaining the current first acid mist exhaust gas pH value at the air inlet in real time; if the first duration is not greater than the second threshold, continuing the step of correcting the current spray volume based on the second spray volume.

[0037] Before correcting the current spray volume based on the second spray volume, the electronic device starts timing based on a preset time to correct the current spray volume, thus obtaining the first timing time. This timing begins when the above steps start. Then, it judges in real time whether the second difference exceeds the first threshold. If so, the first timing stops, and the corresponding first duration is obtained based on the first timing time. The electronic device then judges whether the first duration exceeds the second threshold, which is equal to two-thirds of the preset time. In other words, it judges whether the correction process based on the preset time has lasted for more than two-thirds of the preset time. If the first duration exceeds the second threshold, it indicates that more than two-thirds of the preset time has elapsed. At this point, the electronic device stops executing the step of correcting the current spray volume based on the second spray volume, because a significant amount of time has already been spent on correction and control. Switching to this step would be wasteful and lead to wasted resources. Therefore, it switches to executing the step of real-time acquisition of the first acid mist exhaust gas pH value at the air inlet, i.e., switching to control based on the actual pH value of the acid mist exhaust gas, thus changing the control strategy. If the first duration does not exceed the second threshold, the electronic device continues executing the step of correcting the current spray volume based on the second spray volume.

[0038] As an optional implementation of this application, after outputting the loop processing signal, the method further includes: obtaining a corresponding first increment based on the current pH value of the second acid mist exhaust gas; and correcting the current spraying amount based on the first increment.

[0039] After the electronic device outputs a cycle processing signal, it obtains the corresponding first increment based on the current pH value of the second acid mist exhaust gas. Since it needs to treat both the acid mist exhaust gas entering through the normal inlet and the acid mist exhaust gas that has already undergone one treatment, it is necessary to increase the spray volume to neutralize the acid mist exhaust gas requiring cycle processing while still meeting the normal treatment requirements. The obtained first increment meets the neutralization needs of the acid mist exhaust gas requiring cycle processing, and then the electronic device adjusts the current spray volume based on the first increment.

[0040] As an optional implementation of this application, before correcting the current spraying volume based on the first increment, the method further includes: determining whether a step of gradually changing the current spraying volume to a first spraying volume based on a preset time is being executed; if a step of gradually changing the current spraying volume to a first spraying volume based on a preset time is being executed, then a surplus total is calculated based on the preset time, the current spraying volume, and the first spraying volume; a supplementary total is calculated based on the preset time and the first increment; determining whether the surplus total is greater than or equal to the supplementary total; if the surplus total is greater than or equal to the supplementary total, then the step of correcting the current spraying volume based on the first increment is stopped; if the surplus total is not greater than the supplementary total, then the step of correcting the current spraying volume based on the first increment continues.

[0041] Before the electronic device corrects the current spraying amount based on the first increment, the electronic device determines whether it is executing a step of gradually changing the current spraying amount to the first spraying amount based on a preset time. If this step is being executed, the electronic device calculates the total surplus based on the current spraying amount and the first spraying amount based on the preset time. Because it is a process of gradually reducing the spraying amount within the preset time, the sprayed alkaline solution may be excessive if the pH value of the acid mist exhaust gas does not change. Therefore, the amount of this part of the alkaline solution is calculated.

[0042] The electronic device calculates the total amount to be supplemented based on a preset time and a first increment. Then it determines whether the surplus amount is greater than or equal to the total amount to be supplemented, that is, whether the excess alkali solution is sufficient for supplementation. If the surplus amount is greater than or equal to the total amount to be supplemented, the electronic device stops executing the step of correcting the current spraying amount based on the first increment. If the surplus amount is not greater than the total amount to be supplemented, the electronic device continues to execute the step of correcting the current spraying amount based on the first increment.

[0043] As an optional implementation of this application, after stopping the step of correcting the current spray volume based on the first increment, the method further includes: obtaining the increase value of the current pH value of the second acid mist exhaust gas after one cycle of processing; calculating the reciprocal of the increase value and using the reciprocal as a proportionality coefficient; multiplying the proportionality coefficient and the first increment to obtain the second increment; correcting the current spray volume based on the second increment and outputting a multi-cycle processing signal.

[0044] After ceasing the step of correcting the current spray volume based on the first increment, the electronic device acquires the increase in the pH value of the current second acid mist exhaust gas after one cycle of processing, then calculates the reciprocal of the increase, uses the reciprocal as a proportionality coefficient, multiplies the proportionality coefficient by the first increment to obtain the second increment, and then adjusts the current spray volume based on the second increment to increase the spraying of alkaline solution, and outputs a multi-cycle processing signal to perform multiple neutralization treatments on the acid mist waste, ensuring that the acid mist waste can be completely neutralized and meet emission standards.

The output module 807 is used to output a cyclic processing signal.

[0046] In this optional embodiment, the acid mist exhaust gas treatment control device 800 further includes: The first acquisition submodule is used to acquire the pH value of the third acid mist exhaust gas at the previous moment based on the current moment before correcting the current spraying amount based on the first spraying amount. The first calculation submodule is used to calculate the first difference between the current pH value of the first acid mist exhaust gas and the pH value of the third acid mist exhaust gas; and to take the absolute value of the first difference. The first judgment submodule is used to determine whether the absolute value is greater than the change threshold; if the absolute value is greater than the change threshold, then proceed to the second judgment submodule.
