Abstract
Abstract An electrostatic precipitator for removing mist from a gas stream. A precipitator formed of electrical insulating material, typically resin impregnated glass fiber. A precipitator with a plurality of tubular flow passages, each having a rod conductor within the tube and another conductor within the tube wall. A helical wire conductor embedded between resin impregnated glass fiber layers to form a tubular flow passage.

Claim 1
Independent Claim
175 words
In an apparatus for removing mist from a gas stream, the combination of: a lower housing having a gas inlet and a liquid outlet; an upper housing having a gas outlet, said lower and upper housings being formed of resin impregnated glass fiber; a plurality of tubes interconnecting said lower and upper housings, defining a gas flow path through said gas inlet, lower housing, tubes, upper housing and gas outlet, said tubes supporting said upper housing above said lower housing, each of said tubes comprising inner and outer layers of electrical insulating material with a helical electrical conductor embedded between said layers; a plurality of electrical conducting rods each comprising a core of electrical insulating material helically wrapped with a metal wire incorporating a plurality of outwardly directed poiNts; suspension means for positioning one of said rods in each of said tubes; and means for connecting an electrical power supply to said conductors of said tubes and to said wires of said rods to establish an electrical field between each tube and the rods therein.
