CONCENTRATION DISTRIBUTION APPARATUS FOR AEROSOL PARTICLES, CAPABLE OF IMPROVING RELIABILITY OF A TEST FOR AEROSOL PARTICLES

摘要

PURPOSE: A concentration distribution apparatus for aerosol particles is provided to easily implement various tests according to concentration change of aerosol particles in storage chambers and to supply the aerosol particles to each storage chamber as exact concentration.;CONSTITUTION: A concentration distribution apparatus for aerosol particles comprises a particle generation unit(100), a supply chamber(200), a pressure maintaining device(300), and a particle concentration control unit(500). The particle generation unit generates aerosolized particles to be in constant concentration. The supply chamber stores aerosolized particles generated by the particle generation unit in constant pressure state. In order to supply the aerosolized particles to multiple storage chambers, the multiple storage chambers and the supply chamber are connected. The pressure maintaining device constantly maintains the internal pressure of the supply chamber. The particle concentration control unit is connected to pipes connecting the supply chamber and the multiple storage chambers in order to independently control the concentration of the aerosolized particles flowed in the storage chamber.;COPYRIGHT KIPO 2012
