The invention discloses a laboratory-used mineral aerosol generating system. The aerosol generating system includes a high-pressure air source, a humidity flow control module, a mineral aerosol generating chamber and a mixing chamber. The humidity flow control module includes a humidity flow control branch I and a humidity flow control branch II; a sieve plate loaded with mineral aerosol is arranged in the mineral aerosol generation chamber, and a closed chamber is formed in the mineral aerosol generation chamber; The gas outlets of the humidity flow control branch Ⅰ and the humidity flow control branch Ⅱ are connected to a temperature and humidity probe and a three-way proportional valve in turn; the two outlets of the three-way proportional valve are respectively connected to the mineral aerosol generating chamber and the closed chamber. The chambers are connected; the mineral aerosol generating chamber is connected with the mixing chamber. The mineral aerosol generation system can generate mineral aerosols of different concentrations and humidity, which can be used for the generation of mineral aerosols in different source areas, the inspection and calibration of mineral aerosol equipment, and also meets the research needs of inhalation toxicology tests.
Description
technical field [0001] The invention relates to a laboratory-used mineral aerosol generating system, which belongs to the field of aerosol technology. Background technique [0002] Mineral aerosol is one of the important components of atmospheric aerosol, and a large amount is emitted into the atmosphere every year. Mineral aerosols can affect ground temperature and reduce atmospheric visibility through direct and indirect radiation effects, and at the same time provide a reaction interface for various physical and chemical processes and a carrier for the accumulation of various pollutants. In the actual environment, mineral aerosols are affected by the source and the local environment, and will be affected by the external environment during the transmission process. Therefore, a system that can stably generate mineral aerosol is of great significance for studying the physical and chemical properties of mineral aerosol, simulating the reaction and aging process in the actua...
