Method and device for determining pollutant discharge amount of coal-fired power plant

Abstract

The embodiment of the invention provides a method and device for determining the pollutant discharge amount of a coal-fired power plant, relates to the field of atmospheric pollution monitoring and control, and can determine the optimal discharge amount of pollutants of the coal-fired power plant in combination with meteorological data, topographic data and the concentration condition of PM2.5. The method comprises the steps: acquiring pollutant emission parameters of a coal-fired power plant and meteorological data and topographic data of a preset region; updating a pre-stored pollutant emission source list according to the pollutant emission parameters; calculating an atmospheric PM2.5 concentration simulation value of the preset region according to the pollutant emission source list, the meteorological data and the topographic data and an atmospheric chemical transmission model; judging whether the atmospheric PM2.5 concentration analog value is greater than a preset concentration value or not; when it is determined that the atmospheric PM2.5 concentration simulation value is larger than a preset concentration value, updating the pollutant discharge amount according to a presetrule; when it is determined that the atmospheric PM2.5 concentration simulation value is smaller than or equal to the preset concentration value, outputting the pollutant discharge amount.

Description

technical field [0001] The invention relates to the field of air pollution monitoring and control, in particular to a method and a device for determining the pollutant discharge amount of a coal-fired power plant. Background technique [0002] At present, the total amount control adopted by China macroscopically is the target total amount control, and the allocation of my country's total amount control indicators basically adopts a "top-down" model, that is, the country takes the actual emissions declared by each province (region) as the benchmark. After verification, it will be used as the base, and after appropriate balance and adjustment, the total discharge target of major pollutants will be decomposed to each province, autonomous region or municipality directly under the Central Government, and then the provincial environmental protection bureau will decompose and implement the control target to each prefecture-level city, and then decompose it to each county. , district ...

AI Technical Summary

Problems solved by technology

For coal-fired power plants, although the traditional pollutant concentration control has been shifted to the total amount control, in the specific implementation of the total amount control, after the initial allocation of the total emission amount, the dynamic and planned management of the actual emission amount has not been realized, resulting in Unexpected excess emissions from power plants and regions have brought certain challenges to power generation companies and relevant government departments to implement precise control of total pollutant emissions

Furthermore, although the researchers have carried out target decomposition on the total emissions to analyze the emission reduction potential of coal-fired units, their research still focuses on primary pollutants, and has not included primary pollutant emissions and PM2 in the atmosphere. 5 concentrations are linked together, and cannot effectively improve the atmospheric environment by controlling pollutant emissions
