【発明の名称】改良された静電濾過機
Document Type and Number:
Japanese Patent JPH09504468
Kind Code:
A
Abstract:
An electrostatic filter utilizes two separate filter cartridges in a parallel flow configuration with respect to incoming dielectric fluid containing particulates. Each cartridge is connected to opposite sides of a high voltage power supply, resulting in the electrodes contained in one of the cartridges having an opposite polarity than the electrodes contained in the other cartridge. This, in turn, results in having the fluid borne particulates exiting one cartridge being charged oppositely to those exiting the other. The fluid streams exiting the two cartridges are joined together, allowing the particulates to flocculate. These larger groupings of particulates may then be mechanically filtered in a third cartridge. The parallel flow configuration results in an electrostatic filter that is relatively insensitive to water contained in the dielectric fluid.
