Abstract
A method for separating fine particles from contaminant particles suspended in a gaseous medium. The method includes introducing a particle suspension at a predetermined velocity into a vessel having a top and bottom portion, each portion having a discharge outlet. The particle suspension is then directed into an impingement plate, which is arranged within the vessel at a predetermined angle. The impingement plate is angled to achieve uniform distribution of the particle suspension within the vessel after impact with the plate. The fine particles will rise to the top portion of the vessel, and the contaminant, as well as residual fine particles, will settle to the bottom of the vessel. The fine particles and contaminant and residual fine particles are removed from the top and bottom discharge outlets respectively.
