Composite Discharge Electrode System


Coil wrapped around a pole

The invention is a new design for constructing charging electrodes using composite materials such as carbon nano-fibers and glass fibers in combination with polymers. The primary goal of the technology is to produce low cost composite electrodes that are corrosion resistant. Composites are much lighter than metals, so the weight of the electrodes is also reduced. It provides a highly effective alternative to replace the expensive charging electrodes used in equipments such as ESPs (Electro-Static Precipitators). It uses rods or tubes made of inexpensive polymers and polymer matrix composites. Materials such as silicon carbide can be used to increase the operating temperatures. The composite electrode can also be made of a combination of metal discharge points supported on a polymer or polymer matrix composite. Composites have high strength and can be used to fabricate electrodes of high durability and long operating lives.
