Abstract

The invention relates to an atmospheric aerosol smoke system for simulating an open burning of biomass and measuring a concentration of gaseous pollutants. The system comprises a combustion device forsimulating an open burning of biomass, an aerosol smoke box for simulating emission of atmospheric pollutants into the atmosphere, and a gaseous pollutant concentration measuring device connected insequence. The atmospheric aerosol smoke system of the invention has three functions simultaneously, that is, the process of the open burning of the biomass to emit the atmospheric pollutants can be accurately and truly simulated; the physicochemical reactions of various heights of the atmospheric pollutants produced by the open burning of crop straw in the troposphere and even the stratosphere areartificially controllable and repeatedly simulated, and at the same time the effects of complex meteorological and topographical factors in the actual environment are excluded; and CO analyzers, O3 analyzers, NO-NO2-NOx analyzers, and SO2 analyzers are used for accurately measuring the concentration of the gaseous pollutants in the simulated environment of atmospheric particulates emitted duringa simulated combustion.

Description

technical field [0001] The invention relates to an atmospheric aerosol smog system for simulating open-air burning of biomass and capable of measuring the concentration of gaseous pollutants. Background technique [0002] As a large agricultural country in the world, China ranks first in the world in the possession of crop stalks. According to statistics, more than 20% of the crop stalks are directly burned in the open air. Atmospheric aerosols produced by the open-air burning of crop straws play an important role in the deterioration of environmental quality (such as the formation of smog) and the reduction of visibility, and will participate in atmospheric transport and chemical processes. Their special optical properties and chemical composition affect the surface radiation. It can directly or indirectly affect the climate and gas-liquid circulation as cloud condensation nuclei; in addition, the atmospheric aerosols produced by the open-air burning of crop straws have sig...
