The invention relates to a portable and foldable smoke box, which belongs to the technical field of environmental testing and solves the technical problems that the existing smoke box is not easy to move, has a fixed volume, and cannot be applied to multiple environments at the same time. The smoke box of the present invention includes a smoke box body, a folding and telescopic unit, a fixing unit and a clamping unit; the smoke box body is provided with an outer wall of the smoke box, first and second fixing plates, and the first fixing plate is provided with a gas inlet and outlet , the second fixed plate is provided with a gas and particle monitoring unit; the fixed unit includes the first fixed rod to the fourth fixed rod with the same structure; the folding telescopic unit includes the first to the fourth folding telescopic rods with the same structure and arranged in parallel; One to the fourth fixed rods are hinged with the first to the fourth folding telescopic rods. The smog box provided by the invention has a variable volume and is easy to move, and can be used for collection, photochemical reaction and monitoring of pollution sources outdoors; and can be used for simulation research on the process of generating secondary organic aerosols from volatile organic compounds indoors.
Description
technical field [0001] The invention relates to the technical field of environmental testing, in particular to a portable and foldable smoke box. Background technique [0002] Automobile exhaust and factory exhaust gas contain a large amount of primary pollutants such as nitrogen oxides and hydrocarbons. Under the action of sunlight and ultraviolet rays, photochemical reactions will occur to produce secondary pollutants. The smog formed by their mixture is called photochemical smog. The frequent haze phenomenon in recent years will also accelerate the early arrival of photochemical smog. [0003] The photochemical reactions in the atmosphere are carried out under very complex conditions. Meteorological conditions (wind speed, wind direction, humidity, temperature, light intensity, etc.) and pollutant status (species, concentration, emission sources, etc.) important influence. The smog box simulation system is a device designed to simulate photochemical reactions under simp...
