An electrostatic precipitator suitable for the collection of aerosol-sized particles is developed. This device is a two-stage electrostatic precipitator divided into a corona discharge part and a collection electrode part. Positive ion is charged to the virus particles by corona discharge, and the negative pole of the collection electrode installed in the later stage collects these particles. The particle collection performance of the system is investigated when the inlet velocity (inlet flowrate) is varied. As a result, even at the same inlet velocity, the collection rate increased with smaller particle size. Furthermore, the collection efficiency of particles decreased with increasing flow velocity.
