Embodiment 1

[0051] see figure 1 , thermal power plant discharge soot pollution simulation simulation method of the present invention, comprises the following steps:

[0052] First, obtain the relevant operating data of power generation and electrostatic precipitator of the thermal power plant and the monitoring data of the smoke at the air outlet of the chimney, and combine the meteorological and environmental parameters in the surrounding area of ​​the single thermal power plant (which can be obtained from the Meteorological Bureau) to quantitatively calculate the The impact of smoke and dust pollutants emitted by a single thermal power plant on air quality, establish a smoke diffusion simulation mathematical model of the impact of a single thermal power plant on environmental pollution in a certain surrounding area, and analyze the diffusion mechanism of PM2.5:

[0053] ρ ( x , y , z ...

Embodiment 2

[0076] see figure 1 , the simulation method of smoke and dust pollution from thermal power plants in this embodiment is different from Embodiment 1 in that after completing the quantitative analysis of smoke and dust pollution in thermal power plants, considering the combined effect of the above two models, the following smoke and dust in thermal power plants around the city are established Comprehensive emission analysis, simulation quantitative model:

[0077] ρ ( x , y , z ) = Q 2 π u ‾ σ y σ ...

Embodiment 3

[0083] see figure 1 , figure 2 . The simulation method of smoke and dust pollution from thermal power plants in this embodiment is different from Embodiment 1 and Embodiment 2 in that by quantitatively analyzing the impact of pollution emissions from thermal power companies around the city on urban pollution, the following is established: figure 2 The thermal power plant pollution diffusion dynamic GIS system shown in the figure dynamically displays the pollution situation in 3D simulation in the GIS system, and users can intuitively and visually obtain the pollution diffusion information of different locations in the region.

Abstract

The invention discloses an analogue simulation method for discharged smoke dust pollution of a thermal power plant. The analogue simulation method comprises the following steps: firstly, obtaining relative operation data of power generation and electric dust removal of a power station, and monitoring data of smoke dust of a chimney air outlet; combining weather and environment parameters in the peripheral region of a concerned single thermal power plant to establish a smoke dust diffusion simulation mathematic model in the certain region of the periphery of the single thermal power plant; secondly, considering a polymerization effect of PM2.5 according to electric dust removal operation parameters and environment and weather conditions of the thermal power plant and establishing a diffusion and polymerization simulation mathematic model of influences caused by the environmental pollution of the thermal power plant in the peripheral analyzing region; thirdly, carrying out simulation predication and quantitative calculation on PM2.5 and PM10 pollution emissions respectively and establishing a simulation procedure of comprehensive effects of the two models; and fourthly, considering a plurality of power station comprehensive effects to form a quantitative and simulation analyzing model for the smoke dust emission of the thermal power plant in a researching range to obtain predicated quantitative data of the pollution of the thermal power plant.

Description

technical field [0001] The invention relates to a simulation method for smoke and dust emission pollution of a thermal power plant, in particular to a simulation method for a thermal power plant to discharge smoke and dust pollution after adopting electric dust removal. Background technique [0002] Environmental protection is a necessary activity for human beings to maintain their own lives and homes. In order to develop industries, China has developed a large number of thermal power plants, which has caused great environmental protection problems, especially PM2.5 pollution. Judging from the current research results, the source of PM2.5 composition is complex. The main components include not only carbon, sulfate, etc., but also lead, arsenic, cadmium, copper and other substances that are harmful to human life. PM2.5 particles are tiny, and human beings The breathing filtration system cannot form an effective defense against it. During the diffusion and floating process of ...
