An Experimental Study of an Electrostatic Precipitator Used for the Collection and Sizing of Airborne Particulate Matter

摘要

An experimental investigation to determine the feasibility of using an electrostatic precipitator for sizing airborne micron size particles has been completed. Samples of particles with known radii and physical properties were injected into the precipitator under controlled conditions. The resulting deposition patterns were measured and checked against a mathematical model previously developed at the Air Force Institute of Technology (D. L. Lamberson. A study of the electrostatic precipitation of radioactive aerosols. M.S. Thesis, 1961) but modified by the author. The point at which particles were collected was found to be extremely sensitive to physical properties of the particles sampled so that an electrostatic precipitator could not separate particles into size fractions unless the particles sampled had the same physical properties.
