Erosion-resistant conductive composite material collecting electrode for WESP
View Patent ↗A collecting electrode for use in wet electrostatic precipitators, the collecting electrode being fabricated from an electrically-conductive, corrosion resistant and temperature and spark resistant composite material comprising carbon fiber and thermosetting resin so as to pro\ the collecting electrode with an improved arc resistance, as dictated by erosion density and direction, by controlling the weave pattern and/or fabric thickness of the carbon fibers.
1. A collecting electrode for a wet electrostatic precipitator fabricated from an electrically-conductive, corrosion resistant and temperature and spark resistant composite material, the composite material comprising a generally evenly woven carbon fiber within a thermosetting resin in a cross-linked structure, wherein erosion direction and density on the electrode is controlled by varying the weave pattern of the carbon fibers and fabric thickness of the carbon fibers.
2. The collecting electrode claimed in claim 1 , wherein the carbon fibers are woven in a 2×2 twill arrangement.
3. The collecting electrode claimed in claim 1 , wherein increasing the tightness of the weave pattern of the carbon fibers increases the density on the electrode.
4. The collecting electrode claimed in claim 1 wherein increasing the thickness of the carbon fibers creates erosion lines with fewer turns and branching.
