- Abstract
- An electrospraying (E/S) and a corona discharging experiment are carried out to investigate the charging characteristics of sub-micron particles. The measurement of particle charging and collection efficiency was conducted with electrometer, condensation nuclei counter (CNC) and scanning mobility particle sizer (SMPS) . E/S is a process that relies on electrostatic force to break the liquid into fine charged droplets. During this process many highly charged small droplets or ions are attached to the foreign particles and eventually charge the particles. This processing is unique and distinct from corona discharging. The difference in charging rate between corona discharge and E/S results in the difference in collection efficiency for sub-micron particles. The control of particles by charging and collection with E/S and corona discharge has been investigated experimentally. The result shows that the collection efficiency of E/S-ESP system is higher than 99.9 % for particles with a geometric mean diameter (GMD) of 50 ∼ 100 nm at the mean face velocity of 0.5 m/s and 1.0 m/s.
