Abstract

The invention provides a gas shooting detection system. The gas shooting detection system comprises a gas mixing regulation device, a gas chamber device, a light source, a spectrometer and a shootingdevice, wherein the gas mixing regulation device comprises a flow regulator, an inert gas humidity generator, a gas mixer, a to-be-detected gas supply bottle and an inert gas supply bottle; the gas chamber device comprises a gas absorption detection pool; a gas inlet of the gas chamber device is connected with a gas outlet of the gas mixing regulation device; the gas absorption detection pool comprises a light inlet hole, a white cell structure, a light outlet hole and a camera shooting port; a light path converter is arranged at the positions of the light outlet hole and the camera shooting port; the shooting device comprises a filter and a camera; the filter comprises a plurality of filter sheets arranged on a filter wheel; and the shooting device is connected with the camera shooting port. The gas shooting detection system provided by the invention also can implement detection on pollution gas with different concentrations and different humidity degrees, and is helpful for establishing a pollution gas shooting detection data model.

Description

technical field [0001] The invention relates to the technical field of pollutant gas concentration detection, in particular to a gas photographing and detection system. Background technique [0002] SO 2 (Sulfur dioxide), also known as sulfurous anhydride, is one of the main pollutants in the atmosphere. SO 2 It is a colorless polluting gas with a density greater than that of air. The main harm to the human body is that inhalation of it into the lungs will cause respiratory irritation and burning sensation, which will damage human health; the harmful effects on the natural environment include acidification, smog and sensitivity to ecosystem damage. SO 2 It can also lead to poor air quality, mainly through the formation of scattering and absorption of solar energy, affecting the Earth's atmospheric aerosol radiation budget. [0003] Currently for SO 2 There are many detection methods used, such as ultraviolet fluorescence method SO 2 The monitoring instrument mainly ad...
