System and method for in-situ conditioning of emitter electrode with silver

摘要

Cleaning and/or conditioning electrode surfaces can provide significant performance and operational benefits in EHD devices. In particular, conditioning of emitter electrode surfaces with silver (Ag), silver compositions or silver preparations applied in situ at successive times throughout the operating lifetime of an EHD air mover has been found to significantly reduce ozone production. Structures and techniques are described for in situ conditioning electrode surfaces and, in particular, emitter electrode surfaces of an EHD device such as an air mover or precipitator, with a conditioning material that includes silver.

1. An apparatus comprising:
an electrohydrodynamic (EHD) device that includes an emitter electrode energizable to motivate ion flow; and a conditioning surface to frictionally engage the emitter electrode, wherein the conditioning surface and a frictionally engaged surface of the emitter electrode are movable relative to one another to, at successive times throughout the operating life of the apparatus, deposit a conditioning material comprising silver on the frictionally engaged surface of the emitter electrode.
