Compact high efficiency electrostatic precipitator for droplet aerosol collection

摘要

An electrostatic precipitator has a high voltage electrode including multiple wire segments that are positioned within, a surrounding electrically conductive porous media having a central axis and wherein the electrode assembly extends along the central axis. The electrode assembly has a plurality of wire lengths positioned to extend in a direction along the longitudinal axis of the porous media, and the wire segments being arranged to have a substantially longer total length than the length of extension along the longitudinal axis. An aerosol containing droplets is passed into the interior of the porous media, and across the electrode, which is charged with a high voltage. The porous media is at a substantially lower or different voltage from the high voltage electrodes. Flow of the aerosol containing particles charged by the electrode passes through the porous media to the outlet and the charged particles are precipitated by the porous media. Electrostatic shields are provided around high voltage insulators to reduce the likelihood of contamination of the insulators, which causes unsatisfactory current leakage.
