[0017] To make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, the first xx script may be referred to as the second xx script, and similarly, the second xx script may be referred to as the first xx script.

[0019] As Figure 1 shown, a method for warning of excessive concentration of organized waste gas emissions provided by an embodiment of the present invention, the method includes: S100, obtaining detection device data, the detection device being an on-line detection device, the detection device data including the pollutant concentration of the gas, the pollutants including sulfur dioxide, nitrogen oxides, particulate matter and volatile organic compounds.

[0020] In this step, detection device data is obtained, the detection device being an on-line detection device. The on-line detection device includes a gas sampling device, a gas analyzer, a particulate matter measuring instrument, a data processing unit and an environmental parameter monitor. The gas sampling device is used to extract a flue gas sample from an exhaust stack or a discharge pipe, and the gas analyzer is used to analyze gas pollutants; The particulate matter measuring instrument is used to measure the concentration of particulate matter. The data processing unit is used to receive, store and analyze the detection data and upload it to the central control system. The environmental parameter monitor is used to monitor temperature, humidity, flow rate and oxygen content to correct the error of the measurement data; The detection device data includes the pollutant concentration of the gas, the pollutants including sulfur dioxide, nitrogen oxides, particulate matter and volatile organic compounds. Whether the emission concentration of the organized waste gas is qualified is determined by monitoring the pollutants.

[0021] S200, obtaining a detection threshold, the detection threshold being the maximum allowable value of the pollutant concentration in the air, comparing the detection data with the detection threshold, determining the pollution source according to the pollution result, obtaining the pollution source treatment method, and sending the treatment method to the terminal.

[0022] In this step, the detection threshold is obtained. The detection threshold is the maximum allowable value of the pollutant concentration in the air. The detection data is compared with the detection threshold, the current concentration value of each pollutant is obtained, and it is compared with the detection threshold stored in the database. If the concentration of a certain pollutant exceeds the detection threshold, it is determined that it exceeds the standard and the warning mechanism is triggered; Determine the pollution source based on the polluted results. When it is found that the pollutants exceed the standard, it is necessary to determine the pollution source, compare the historical data of the same emission outlet, and judge whether it is continuous or accidental over-standard. Obtain the operating parameters of the emission equipment, such as temperature, flow rate, and filtration status, and analyze the abnormal situation of the equipment.

[0023] S300. Compare the processing results with the detection threshold to obtain the second comparison result. Classify the pollutant concentrations below the threshold, obtain the classification rules, and the higher the pollutant concentration, the higher the warning level.

[0024] In this step, compare the processing results with the detection threshold. After implementing the pollution treatment measures, it is necessary to detect the pollutant concentration again and compare the latest detection data with the set detection threshold to determine the effectiveness of the treatment measures. This process is called the second comparison; Obtain the second comparison result. For pollutants that have been reduced below the detection threshold, it is necessary to further subdivide their concentrations for risk assessment and early warning management. The main goal of pollutant classification is to distinguish different levels of compliance, ensure that emissions are within a safe range, set warning levels, and even if the pollutants meet the standards, they can be classified and managed according to the concentration level; Obtain the classification rules. Classify by the percentage of pollutant concentration to the threshold. The higher the pollutant concentration, the higher the warning level.

[0025] S400. Perform visual processing based on the equipment data, predict the subsequent pollutant concentration through the visual processing results, obtain the prediction result, determine the cause of pollutant generation based on the prediction result, obtain the solution to the cause of pollutant generation, and send the solution to the terminal.

[0026] In this step, perform visual processing based on the equipment data. In order to more intuitively analyze the emission trend of pollutants, the system will perform visual processing on the real-time monitoring equipment data, and predict the future concentration of pollutants based on the visual data; Obtain the prediction result, determine the cause of pollutant generation based on the prediction result. When the prediction result shows that the pollutant concentration is about to exceed the standard, it is necessary to analyze the pollution source. According to the cause of pollutant generation, the system automatically matches the best treatment plan to ensure that the pollutant concentration is reduced to a safe level. After confirming the best pollution treatment plan, the solution will be sent to the relevant terminal to ensure that relevant personnel can take measures in a timely manner.

[0027] As Figure 2 shown, as a preferred embodiment of the present invention, the steps of obtaining the detection threshold, where the detection threshold is the maximum allowable value of the pollutant concentration in the air, comparing the detection data with the detection threshold, determining the pollution source based on the polluted results, obtaining the treatment method for the pollution source, and sending the treatment method to the terminal specifically include: S201, obtain the detection threshold, where the detection threshold is the maximum allowable value of the concentration of pollutants in the air. Compare the detection data with the detection threshold to obtain a comparison result, and determine whether the pollutants exceed the standard according to the comparison result.

[0028] In this step, obtain the detection threshold. The detection threshold is the maximum allowable value of the concentration of pollutants in the air. The maximum allowable concentration of sulfur dioxide (SO2) is 500 mg / m³, the maximum allowable concentration of nitrogen oxides (NOx) is 300 mg / m³, the maximum allowable concentration of particulate matter (PM) is 50 mg / m³, and the maximum allowable concentration of volatile organic compounds (VOCs) is 200 mg / m³. Compare the detection data with the detection threshold. If the pollutant concentration ≤ the set threshold, it is considered that the pollutant emissions meet the standard. If the pollutant concentration > the set threshold, it is considered that the pollutants exceed the standard. Obtain the comparison result, directly compare the pollutant concentration value. If it exceeds the allowable value, mark it as exceeding the standard and enter the warning process.

[0029] S202, obtain the determination result, where the determination result includes not polluted and polluted. Determine the pollution source according to the polluted result, and obtain the treatment method for the pollution source. The treatment method is used to harmlessly treat the pollutants.

[0030] In this step, obtain the determination result. The determination result includes not polluted and polluted. Not polluted means that the concentrations of all detected pollutants are lower than the maximum allowable threshold, and the emissions meet the standards. Polluted means that the concentration of at least one pollutant exceeds the threshold, which may have an impact on the environment or human health, and it is necessary to further trace the pollution source and take control measures. Determine the pollution source according to the polluted result. By deploying sensors at multiple monitoring points, compare the pollutant concentrations at each point, find the highest point of pollutants, and determine the possible location of the pollution source. For example, deploy 10 VOCs detection stations in an industrial park. If the concentration at Station A is the highest, the area near Station A may be the pollution source. Obtain the treatment method for the pollution source. After determining the pollution source, the system automatically matches the optimal treatment method for the pollution source to ensure that the pollutants are harmlessly treated. For SO2 treatment, the concentration of limestone slurry can be increased to 5%-10%, the spray flow can be increased, and the absorption efficiency of the desulfurization tower can be improved. Ensure that the inlet temperature of the desulfurization tower is between 120-150°C to improve the absorption effect. For NOx treatment, the ammonia injection amount can be adjusted to prevent secondary pollution caused by ammonia escape and ensure the activity of the catalyst to avoid failure. For PM treatment, check whether the filter bag is damaged. If it is damaged, it needs to be replaced immediately, and adjust the dust cleaning frequency to avoid dust accumulation affecting the dust removal efficiency. For VOCs treatment, ensure that the combustion temperature is between 750-850°C to improve the VOC removal efficiency, and regularly check the catalyst status to avoid a decrease in activity.

[0031] S203. Verify the corresponding treatment method according to the pollution source and send the treatment method to the terminal.

[0032] In this step, verify the corresponding treatment method according to the pollution source. After confirming the pollution source, the system needs to match the most suitable treatment method to ensure that the pollutant emissions return to within the safety threshold. After determining the applicable pollution control plan, the system automatically sends the treatment plan to the relevant terminals to ensure that enterprises or environmental protection supervision departments can take measures promptly.

[0033] As Figure 3 shown, as a preferred embodiment of the present invention, the step of comparing the treatment result with the detection threshold to obtain a second comparison result, dividing the pollutant concentration below the threshold, and obtaining the division rule, where the higher the pollutant concentration, the higher the warning level, specifically includes: S301. Treat the pollutants according to the treatment method, obtain the treatment result, compare the treatment result with the detection threshold to obtain a second comparison result, and determine whether the treatment method is effective according to the second comparison result.

[0034] In this step, treat the pollutants according to the treatment method. The treatment methods for pollutants include source control, process control, and end treatment. Optimize the combustion conditions and reduce pollutant generation through source control, use adsorption, catalysis and other technologies through process control to treat pollutants before they enter the emission stage, and remove pollutants through desulfurization, denitrification, dust removal and other methods through end treatment; Obtain the treatment result. After the pollution treatment measures are implemented, it is necessary to re-detect the pollutant concentration to obtain the latest emission data of the pollutants to determine the actual effect of the treatment measures. After obtaining the pollutant concentration data after treatment, it is necessary to perform a second comparison with the detection threshold to determine whether the pollutants meet the standards: Pollutant concentration ≤ set threshold → treatment is effective and meets the standards; Pollutant concentration > set threshold → treatment is ineffective and the treatment plan needs to be optimized.

[0035] S302. If the determination result is lower than the threshold, it is determined that the treatment method is effective. If the determination result is higher than the threshold, it is determined that the treatment method is ineffective, and then re-select the treatment method.

[0036] In this step, if the determination result is lower than the threshold, after the pollutants are treated, it is necessary to re-detect their concentration and compare it with the set detection threshold to determine whether the treatment method is effective. If the pollutant concentration after treatment is lower than the detection threshold, it indicates that the treatment measures have achieved the control target and the pollutant emissions meet the standards; The concentration of pollutants after treatment is still higher than the detection threshold, indicating that the current treatment plan fails to effectively reduce pollutants and it is necessary to reselect or optimize the treatment method. For example, adjust the operating parameters of existing equipment to increase the treatment capacity, such as increasing the spray volume or replacing the filter bag type.

[0037] S303, classify the pollutant concentration below the threshold to obtain a classification rule, which is used to distinguish different warning methods for the pollutant concentration below the threshold. The higher the pollutant concentration, the higher the warning level.

[0038] In this step, classify the pollutant concentration below the threshold. When the pollutant concentration is below the set emission threshold, although it is not in an over-standard state, it may still have a potential impact on the environment. Therefore, it is necessary to classify the pollutant concentration below the threshold for risk monitoring and early warning; Obtain a classification rule, which is used to distinguish different warning methods for the pollutant concentration below the threshold; Table 1: Classification table Warning Level Pollutant Concentration Range (% Threshold) Treatment Method Level 1 (Safe) 0 - 50% Maintain the status quo and conduct normal monitoring Level 2 (Attention) 50 - 75% Enhance monitoring and optimize treatment equipment Level 3 (Warning) 75 - 100% May be about to exceed the standard, adjust the treatment strategy Level 4 (Severe Alarm) ≥ 100% Exceeded the standard, rectify immediately When the system completes the classification of pollutant concentration, the warning information will be automatically sent to the relevant terminals to ensure that relevant personnel respond in a timely manner.

[0039] Such as Figure 4 As shown, as a preferred embodiment of the present invention, the steps of performing visual processing according to device data, predicting the subsequent pollutant concentration through the visual processing result, obtaining the prediction result, determining the cause of pollutant generation according to the prediction result, obtaining the solution to the cause of pollutant generation, and sending the solution to the terminal specifically include: S401, obtain the data of existing detection equipment, perform visual processing according to the device data. The visual processing uses a line chart to obtain the visual processing result, and predict the subsequent pollutant concentration through the visual processing result.

[0040] In this step, obtain the data of existing detection equipment. A line chart is an intuitive way to show the change trend of pollutant concentration, which helps to analyze the change law of pollutant concentration and identify abnormal fluctuations. Perform visual processing according to the device data. The main role of line chart visualization is to identify the change trend of pollutant concentration and discover potential problems; Obtain the visual processing result, which can be used for trend judgment and anomaly detection. Trend judgment is that if the pollutant concentration continues to rise, it may mean that the efficiency of the treatment equipment has decreased, or the production process parameters have not been optimized. If the pollutant concentration fluctuates greatly in a short period of time, it may indicate that an anomaly has occurred in a certain process link, such as a failure of the desulfurization spray system; Abnormal detection is that the SO2 concentration rises sharply in a short period of time, which may indicate insufficient addition of desulfurizer, and the sudden increase in NOx concentration may indicate insufficient ammonia injection or catalyst aging.

[0041] S402, obtain the prediction result, determine the cause of pollutant generation according to the prediction result, obtain the solution to the cause of pollutant generation, obtain the corresponding solution according to the cause of pollutant generation, and send the solution to the terminal.

[0042] In this step, obtain the prediction result and predict the change trend of future pollutant concentration. The prediction result is used to discover potential over-standard risks in advance so as to take targeted measures. Determine the cause of pollutant generation according to the prediction result, analyze the pollution source, and the analysis of the pollution source includes the analysis of the equipment operation status, the comparison of production process parameters, and the influence of environmental factors; The analysis of the equipment operation status checks the working status of the pollution control equipment. The aging or efficiency decline of the equipment may lead to an increase in pollutant concentration; the comparison of production process parameters compares the production process parameters in different time periods, such as combustion temperature, flue gas flow rate, desulfurizer addition amount, etc. If a certain parameter fluctuates abnormally, it may be the cause of pollution exceeding the standard. The influence of environmental factors combines meteorological data, such as wind speed, humidity, and temperature, to judge whether pollutants accumulate due to poor diffusion; According to the cause of pollutant generation, the system automatically matches the best treatment plan to reduce the pollutant concentration and prevent exceeding the standard. For SO2 treatment, the concentration of limestone slurry can be increased to 5%-10%, the spray flow rate can be increased, the absorption efficiency of the desulfurization tower can be improved, and the inlet temperature of the desulfurization tower can be ensured to be between 120-150°C to improve the absorption effect; For NOx treatment, the ammonia injection amount can be adjusted to prevent secondary pollution caused by ammonia escape and ensure the activity of the catalyst to avoid failure; For PM treatment, check whether the filter bag is damaged. If it is damaged, it needs to be replaced immediately, and adjust the dust cleaning frequency to avoid dust accumulation affecting the dust removal efficiency; For VOCs treatment, ensure that the combustion temperature is between 750-850°C, improve the VOCs removal efficiency, and regularly check the catalyst status to avoid a decline in activity.

[0043] S403, obtain the treatment result according to the solution, re-perform visual prediction according to the treatment result, and determine whether the solution is effective according to the re-prediction result.

[0044] In this step, obtain the treatment result according to the solution. When the predicted concentration of pollutants exceeds the standard, the system will match a suitable treatment plan according to the pollution source and implement corresponding optimization measures. After implementing the treatment plan, it is necessary to conduct a secondary detection of the pollutant concentration to obtain the treatment effect data; Perform visual prediction again based on the processing results, perform secondary visualization processing on the new pollutant concentration data, and predict the future trend again. An effective solution is that the pollutant concentration decreases after treatment and it is predicted that it will not exceed the standard in the future; a partially effective solution is that the pollutant concentration decreases to some extent but is still close to the emission threshold, and the operating parameters of the equipment need to be further optimized to ensure long-term compliance; an ineffective solution is that the pollutant concentration does not decrease significantly after treatment and it is predicted that it may still exceed the standard in the future, and the treatment technology needs to be replaced or additional auxiliary treatment means need to be added.

[0045] For partially effective or ineffective solutions, match more precise optimization strategies according to the latest prediction results, and send the optimized solutions to relevant terminals to ensure that relevant personnel can adjust the equipment in a timely manner.

Perform visualization processing based on the device data, predict the subsequent pollutant concentration through the visualization processing result, obtain the prediction result, determine the cause of pollutant generation according to the prediction result, obtain the solution to the cause of pollutant generation, and send the solution to the terminal.
