Wet electrostatic precipitator system components
The present invention relates to the use of corrosion, temperature and spark resistant electrically conductive components in wet electrostatic precipitator systems (WESPs). In particular, the present invention is directed to using a conductive composite material in the fabrication of wet electrostatic precipitator system components.
1. A collecting electrode tube for use in a wet electrostatic precipitator, the collecting electrode tube fabricated from an electrically conductive, corrosion and spark resistant, and temperature-resistant composite material consisting essentially of carbon fiberglass within a thermosetting resin in a cross-linked structure or carbon fibers woven into a seamless biaxial material tube within a thermosetting resin.
2. The collecting electrode tube of claim 1 wherein the collecting electrode tube is in direct contact with a process gas stream passing through the wet electrostatic precipitator.
3. The collecting electrode tube of claim 1 wherein the collecting electrode tube is one of cylindrical, hexagonal and plate type.
4. The collecting electrode tube of claim 1 wherein the composite material withstands corona voltage flash over and power arcs up to 100,000 V.
5. A wet electrostatic precipitator comprising a component intended to be in direct contact with a process gas stream passing through the wet electrostatic precipitator, said component being a collecting electrode tube, or a bundle of collection collecting electrode tubes, each collecting electrode tube fabricated from an electrically conductive, corrosion and spark resistant, and temperature-resistant composite material consisting essentially of carbon fiberglass within a thermosetting resin in a cross-linked structure or carbon fibers woven into a seamless biaxial material tube within a thermosetting resin.
