Embodiment 1

[0030] Embodiments of the present application provide a method for arranging sensors for monitoring air pollutants in chemical parks, such as figure 1 shown, figure 1 This is a schematic flowchart of a sensor layout method for monitoring air pollutants in a chemical industry park in the embodiment of the application. The sensor layout method includes:

[0031] S1: Using the meteorological data in the chemical park and the location data of the elevated point source as parameters, establish an elevated point source diffusion model.

[0032] Among them, the meteorological data in the chemical industry park includes: average wind speed, wind direction, air pressure and temperature in the chemical industry park.

[0033] The location data of the elevated point source in the chemical park includes: the height of the elevated point source from the ground, and the horizontal and vertical distances between the air pollutants diffused from the elevated point source and the elevated poi...

Embodiment 2

[0052] Embodiments of the present application provide a method for arranging sensors for monitoring air pollutants in chemical parks, such as figure 2 shown, figure 2 This is a schematic flowchart of another sensor layout method for monitoring air pollutants in a chemical industry park in the embodiment of the present application. After step S3 in the first embodiment, the sensor layout method further includes:

[0053] S4: If the actual meteorological data or the position data of the elevated point source in the chemical industry park where the sensor deployment location has been determined has changed, step S2 is performed again.

[0054] Specifically, when the real-time meteorological data in the chemical industrial park or the location data of the elevated point sources set in the chemical industrial park to be laid out change, step S2 is re-executed, that is, the atmospheric emission through several elevated point sources in the chemical industrial park to be laid out i...

Abstract

The invention provides a chemical industry park atmospheric pollutant monitoring sensor layout method, and belongs to the field of industrial park air monitoring, and the method comprises the steps: taking meteorological data and elevated point source position data in a chemical industry park as parameters, and building an elevated point source diffusion model; acquiring actual meteorological data, elevated point source position data and atmospheric pollutant emission source intensity in the chemical industry park, and inputting the data into the elevated point source diffusion model to obtain atmospheric pollutant diffusion data; and according to the atmospheric pollutant diffusion data, determining a sensor arrangement position in the chemical industry park. As the application can simulate the pollutant diffusion path of the emission source, the layout of the sensors can be optimized, redundant sensors can be reduced, and the atmospheric environment quality data can be monitored scientifically and precisely.

Description

technical field [0001] The present application relates to the field of air monitoring in industrial parks, and in particular, to a sensor layout method for monitoring air pollutants in chemical parks. Background technique [0002] With the development of the economy, the emission requirements of chemical industrial parks are becoming more and more strict, especially the VOCs (Volatile Organic Compounds, volatile organic compounds) in chemical industrial parks participate in the formation of ozone and secondary aerosols in the atmospheric environment, which has a negative impact on regional Atmospheric ozone pollution and PM2.5 pollution have important impacts. Most VOCs have unpleasant special odor, and have toxic, irritating, teratogenic and carcinogenic effects, especially benzene, toluene and formaldehyde, which can cause great harm to human health. VOCs are important precursors to urban haze and photochemical smog, mainly from coal chemical, petrochemical, fuel paint ma...
