The salt granules aerosol generating apparatus consists of a fan, a filter, a dryer, an air heater, a Venturi tube, a salt solution storage tank, a metering pump, an aerosol generating chamber, a controller and an online laser particle size analyzer. According to the apparatus, an acoustic agglomeration technology is applied to the salt granules aerosol generating apparatus, the size of the salt granules is adjusted by controlling the frequency of sound waves, and a salt granule aerosol generating apparatus capable of controlling the granule size is provided for relevant scientific research. The apparatus has the advantages that the granule size of the salt granules can be rapidly and conveniently adjusted and controlled.

Description

technical field [0001] The invention relates to the field of aerosol generation, in particular to a salt particle aerosol generation device based on acoustic wave agglomeration. Background technique [0002] Sulfur dioxide (SO2) emitted from industrial and agricultural production and living processes 2 ), nitrogen oxides (NOx) and ammonia (NH 3 ) The sulfate, nitrate and ammonium salt formed by chemical reaction are important components of atmospheric particulate pollutants. In the research field of controlling and eliminating atmospheric particle pollutants, there is an urgent need for an aerosol generating device capable of controlling the particle size of salt particles. The salt particle aerosol generated by the device can be used for scientific experimental research such as simulation, testing, evaluation, and inspection of the gas environment, especially for experimental research on the particle aerosol of sulfate, nitrate and ammonium salt. [0003] After the satur...
