Abstract
Provided are an apparatus and a system for classifying particles. The apparatus for classifying particles includes: an internal electrode which has a column shape; an external electrode which is spaced apart from the internal electrode and disposed to surround the internal electrode, and generates an electric field through an interaction with the internal electrode; and an aerosol supply unit which supplies aerosol particles to a separation space between the internal electrode and the external electrode, in which the separation space, through which the aerosol particles are introduced into the particle classifying apparatus and flow, is formed to be narrowed toward a lower aerosol flow side from an upper aerosol flow side into which the aerosol particles are introduced.

An apparatus for classifying particles, the apparatus comprising:
- an internal electrode which has a column shape;
- an external electrode which is spaced apart from the internal electrode and disposed to surround the internal electrode, and generates an electric field through an interaction with the internal electrode;
- and
- an aerosol supply unit which supplies aerosol particles to a separation space between the internal electrode and the external electrode,
- wherein the separation space, through which the aerosol particles are introduced into the apparatus for classifying particles and flow, is formed to be narrowed toward a lower aerosol flow side from an upper aerosol flow side into which the aerosol particles are introduced, and
- wherein the external electrode includes a plurality of electrode rings stacked and connected in an up and down direction, and the aerosol particles are discharged to an outside through a portion between two adjacent electrode rings of the plurality of electrode rings.
A system for classifying particles, the system comprising:
- a particle classifying apparatus which has an air supply unit for supplying air, and at least one classified particle discharge hole for classifying aerosol particles according to the size and discharging the aerosol particles;
- an air saturator which is connected to the particle classifying apparatus and saturates the air to make a saturated vapor;
- and
- at least one condenser which is provided separately from the air saturator and connected to the particle classifying apparatus or the air saturator, and condenses the aerosol particles included in the saturated vapor.
