Industrial area air monitoring method based on rainy and snowy weather

Abstract

The invention discloses an industrial area air monitoring method based on rainy and snowy weather, which belongs to the technical field of air monitoring. A controller and a detection bench are arranged, a circulating air pump and a foreign matter container are arranged in the detection bench.The method comprises the following steps that the detection bench is automatically opened through the controller; then, the circulating air pump and the foreign matter container are started; air flow is accelerated through the circulating air pump; the foreign matter container is gradually moved out to the outer side of the detection bench for containing rain and snow dissolved with pollution gas.Rain and snow in which pollution gas is dissolved are subjected to heating treatment, the polluted gas isrecovered from the liquid phase to the gas phase and is mixed into the air again, air components are reduced to the maximum extent, the components and the content range of the polluted gas in the airenvironment are fully detected by detecting the air before and after reduction respectively, and the air quality detection accuracy in rainy and snowy weather is greatly improved.

Description

technical field [0001] The invention relates to the technical field of air monitoring, in particular to an air monitoring method in industrial areas based on rainy and snowy weather. Background technique [0002] Air quality detection refers to the detection of air quality. The quality of air quality reflects the level of pollutant concentration in the air. Air pollution is a complex phenomenon, and the concentration of air pollutants at a specific time and place is affected by many factors. The emission of man-made pollutants from stationary and mobile pollution sources is one of the most important factors affecting air quality, including vehicle, ship, and aircraft exhaust, industrial enterprise production emissions, residents' living and heating, and waste incineration. Urban development density, topography and weather are also important factors affecting air quality. [0003] my country's ambient air quality monitoring network covers four levels: national, provincial,...

AI Technical Summary

Problems solved by technology

[0004]In recent years, air pollution accidents have occurred frequently in my country, especially complaints about atmospheric volatile organic compounds (VOCs) such as odor in industrial areas have remained high. The problem of odor complaints from air pollution accidents in industrial areas is very serious. Therefore, it is urgent to monitor and control the air environment near industrial areas. Under the action of snow, some polluting gases in the atmosphere can be dissolved in water, which changes the composition of polluting gases in the air and reduces the concentration of polluting gases, especially in the environment of industrial areas, which has a great impact on air components. Therefore, in this There is a large error in the monitoring of the air environment
