Electrostatic precipitator

Abstract

Abstract Covers an electrical precipitator composed of two tandem electrostatic sections arranged to eliminate dust or dirt or any form of particulate matter which may be conveyed with air or gas or any other fluid medium. The first section may, for example, include one or more pairs of positively charged vertical plates between each pair of which are positioned a plurality of negatively charged vertical wires, so that a Corona discharge may be developed between the vertical wires and the two parallel plates of each pair to electrically charge the particulate matter transmitted between the vertical plates. The second section, which is contiguous to the end of the first section and constitutes an add-on for the first section, includes a plurality of metallic grids which are parallel to each other, but perpendicular to the plates of the first section. The first and last grids of the second section may be connected to a source of voltage which does not create a corona field, and the remaining grids of the second section are ''''floated'''' between the first and last grids so as to become charged by voltage induced in such grids so that particles of matter entering the second section and traversing the opening of the various grids will respond to the electric field between adjacent grids and to the aerodynamic flow pattern developed between all of the grids, so that the particulate matter may be collected and removed from the fluid medium.
