Description
Technical Field
The invention relates to the technical field of atmospheric detection, in particular to an atmospheric comprehensive detection system and method based on continuously adjustable small-angle scattering spectrum.
Background
The atmosphere refers to air surrounding the earth, and the atmosphere has complex components, and besides high content of nitrogen and oxygen, the atmosphere also contains a large amount of aerosols and other gases, and the aerosols and other gases have great influence on weather, climate forecast, global water circulation, human health, the earth environment and the like, so the components of the atmosphere need to be detected to better protect the earth environment and human health.
Aerosol refers to a gaseous dispersion of solid or liquid particles suspended in a gaseous medium. The commonly used PM2.5 and PM10 in environmental monitoring is an indication of aerosol concentration in the atmosphere, PM2.5 indicates aerosol particles having an aerosol particle diameter of less than 2.5 microns, and PM10 indicates aerosol particles having an aerosol particle diameter of less than 10 microns. In the prior art, the method of gamma ray or oscillating balance is mostly adopted to detect the aerosol in the atmosphere, and both methods are weight-based measuring methods and can only give out the total amount of the aerosol with the diameter less than 2.5 microns or less than 10 microns. The number of aerosol particles with different particle diameters, namely the distribution form of an aerosol particle spectrum, cannot be distinguished, and the aerosol particle spectrum and the optical characteristics thereof are important parameters for describing physical and radiation characteristics of the aerosol and are also important input parameters in an environment prediction model, so that the real condition of the aerosol cannot be well detected by adopting a gamma ray method or a vibration balance method.
In order to overcome the disadvantages of the gamma ray method or the vibration balance method, some aerosol particle spectrum measuring methods are developed in the prior art, and these methods can be roughly divided into two types, the first type is an optical method, which measures the intensity estimation of laser light at different angles by introducing air flow into a laser cavity, and the second type is a kinetic method, which measures by introducing air flow into a group of filter membranes with different aperture sizes. These measurement methods can only obtain the aerosol particle spectrum at the measurement location, and the spatial representativeness is poor and at the same time the cost is high. In fact, the distribution of the scattering of sunlight by aerosol particles in different directions is related to the size of the aerosol particles and the measurement wavelength, so that the particle spectrum of the aerosol can be detected by acquiring a small-angle scattering spectrum close to the sun direction by utilizing the characteristic. At present, sunlight detection equipment such as a sunlight photometer can only realize direct sunlight or measurement at a certain angle, the field angle of the instrument is fixed, the instrument cannot be changed according to requirements, the measurement at different angles can only be realized in a scanning mode, and the small-angle scattering measurement required by aerosol spectrum measurement cannot be realized.
In addition, various existing detection devices can only detect single components of the atmosphere, and if the atmosphere is required to be comprehensively detected, various different devices are required to be used simultaneously, so that the detection efficiency is low, and the cost is high.
