Atmospheric environment simulation experiment cabin

Abstract

The invention relates to atmospheric environment simulation experiment equipment which can simulate a single or compound air pollution factor environment and atmospheric states of different altitude heights in an actual environment, can accurately simulate the temperature, the humidity and the illumination environment in an urban environment to reduce the atmospheric environment in a real city and can provide stable and precise biological cultivation conditions. On the premise of preventing secondary pollution, the atmospheric environment simulation experiment equipment can be used for single or compound air pollutant biologic effect researches and atmospheric secondary pollution forming mechanism researches. The atmospheric environment simulation experiment equipment is divided into an outer structure and an inner structure; the outer structure comprises a cabin body, a cabin door, an integrated control cabinet, an artificial simulation pollutant source, a gas treatment system and a gas collection system; the inner structure comprises a stainless steel mesh, an experiment table, a gas circulating system, a temperature and humidity control system, an atmosphere and particle pollutant sampling sensor and an ultraviolet-visible lamp group.

Description

technical field [0001] The invention relates to a kind of experimental equipment for atmospheric environment simulation, which can simulate the environment of single or compound air pollution factors and the atmospheric state of different altitudes in the actual environment, etc., and is used for studying the biological influence of air pollutants or the formation of atmospheric secondary pollution. mechanism etc. Background technique [0002] With the continuous advancement and rapid development of urbanization and industrialization in my country, the problem of urban air pollution is becoming more and more serious. The intensity of air pollution in my country is large and the coverage is wide, showing obvious regional pollution characteristics; in addition, the characteristics of compound pollution are prominent, and air pollution is obvious. The seasonal characteristics are seriously affected. Especially since 2013, smog has occurred with an unprecedented frequency, wide ...

AI Technical Summary

Problems solved by technology

However, relevant research in this direction is still in its infancy, based on the fact that there are relatively few simulation devices used by various research institutions to systematically study air pollutants, and most of them are self-made simulation devices that can only meet their own experimental needs

The atmospheric environment simulation devices used in different laboratories have not been standardized, and problems such as time repeatability and spatial repeatability of experimental data are prone to instability

In addition, the internal environment of these simulated devices cannot meet the basic survival and growth needs of experimental subjects, and is not suitable for research on the biological and health effects of air pollutants
