A nano-scale particle mass capture, particle size screening and generation system

Abstract

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.

Description

technical field [0001] The invention relates to the technical fields of occupational hygiene, environmental management and emergency rescue, in particular to a mass collection, particle size screening and generation system of nano-scale particles. Background technique [0002] Particulate matter in ambient air is a general term for various solid and liquid particles existing in the atmosphere, and its particle size ranges from 0.1 to 100 microns, which is one of the most important pollutants in the air; various particulate substances are uniformly dispersed in the air. A relatively stable and bulky suspension system is obtained, that is, an aerosol system. Among them, fine particles are more likely to enter the human body, stay in the environment for a longer time, and absorb more heavy metals and toxic and harmful substances, so the harm to the human body is also greater. A large number of studies have shown that the increase in the concentration of inhalable particulate m...
