[0002] Thermal power units are electric power units that use coal, oil or natural gas as energy and generate electricity through thermal power. They are widely used in power systems and are an important part of my country's power industry.

[0003] When burning coal, oil or natural gas, thermal power units release large amounts of carbon dioxide, sulfur oxides, nitrogen oxides and particulate matter. These pollutants not only cause air quality to deteriorate, but also cause acid rain, greenhouse effect and harm to human health.

[0004] In modern thermal power plants, it is a common design for multiple thermal power units to share one chimney. When multiple thermal power units share a chimney and different thermal power units use different types of pollutant control technologies, pollutants emitted by different thermal power units gather in the chimney and further react chemically to generate new compounds. The existing pollutant emission management methods for thermal power units ignore the chemical reactions of pollutants in the chimney, resulting in the problem of underestimation of actual emission concentrations and low accuracy of pollutant monitoring in pollutant emission management.

It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0056] Please refer to Figure 1 , Figure 1 The overall flow diagram of the method for managing pollutant emissions from thermal power plants based on data analysis provided in the embodiment of the present application specifically includes the following steps:

[0058] S120: performing component characteristic analysis based on the first pollutant data to determine a similarity coefficient of pollutant components of the thermal power unit;

[0059] The larger the similarity coefficient of pollutant components of thermal power units, the closer the components and chemical properties of pollutants emitted by different thermal power units are, which means that the reaction characteristics of pollutants are also similar. Therefore, when pollutants with similar components are collected in the chimney, the probability of new chemical reactions between pollutants is relatively small due to the consistency of chemical properties. Determine the similarity coefficient of pollutant components of thermal power units, including:

[0060] Acquire the first pollutant data in the flue of each thermal power unit, and convert the first pollutant data into a pollutant component set of each thermal power unit;

[0061] The pollutant component similarity coefficient between thermal power unit i and thermal power unit j is calculated by the pollutant component set. The calculation formula of the pollutant component similarity coefficient between thermal power unit i and thermal power unit j is as follows:

[0062]

[0063] Where P i represents the pollutant component set of thermal power unit i, P j represents the pollutant component set of thermal power unit j, X(P i∩P j ) represents the pollutant component set P i and the pollutant component set P j The number of elements in the intersection, X(P i ∪P j ) represents the calculation of the pollutant component set P i and the pollutant component set P j The number of elements in the union, J(P i ,P j ) represents the similarity coefficient of pollutant components between thermal power unit i and thermal power unit j;

[0064] The pollutant component similarity coefficient of the thermal power unit is calculated by the pollutant component similarity coefficient of the thermal power unit i and the thermal power unit j.

[0068] By obtaining the data of pollutants in each thermal power unit and public chimney, and calculating the reaction coefficient of the pollutant components of the thermal power unit, the reaction potential between pollutants of different units can be quantitatively evaluated. Among them, the introduction of emission mass concentration limits provides a basis for quantifying the degree of environmental harm of each pollutant component, which helps to judge the impact of different pollutant components on the environment. When the reaction coefficient of the pollutant component of the thermal power unit is high, it means that the probability of pollutants from different thermal power units reacting when mixed in the chimney is greater, which leads to the generation of new pollutants or changes in emission concentrations.

The emission mass concentration limit is obtained through the Emission Standard of Air Pollutants for Thermal Power Plants (GB13223-2011);

[0073] By calculating the total emission mass concentration of different pollutant components in the flue of thermal power units, and further comparing the total emission mass concentration of different pollutant components with the pollutant data in the public chimney, the pollutant component concentration variation coefficient is obtained, thereby revealing the concentration variation of each pollutant component. The significance of the pollutant component concentration variation coefficient for the pollutant component reaction coefficient of thermal power units is that it provides a quantitative basis for understanding the reaction degree of pollutants from different units in the shared chimney.
