The invention discloses a large amount of nano-
particle trapping, particle size screening and generating
system, which comprises a large amount of nano-
particle trapping mechanism, a charging mechanism, a particle size screening mechanism and a particle eruption mechanism. The invention can realize particle size sieving and
trapping of external air containing particles of different particle sizes through a
cyclone separation system, a charging device and a high-
voltage electric field, and uniformly suspend nano-scale particles of different particle sizes in a
storage tank filled with special solvents. It can also be stored in the liquid
bottle for
backup, and the high-speed
airflow can also be generated by the high-pressure
air pump, and the storage liquid can be carried through the pressure reducing valve and the delivery pipeline through the
liquid storage bottle of different particle sizes to the
nozzle for high-speed spraying, so as to deliver the required particles to the target environment. Aerosols with different flow rates and different concentrations of particles can be used for
air pollution and personal protection
filtration performance research, as well as
pharmacology and
toxicology research of
aerosol inhalants, which are fundamental and applied in promoting occupational health, environmental governance,
emergency rescue and other fields Research matters.
