Abstract
Discharge electrodes in electrostatic precipitators are protected from erosion caused by power arcs in the area along their length which is closest to the ground electrode plates by a shroud of high temperature insulating plastic such as Teflon. The shroud is formed in two longitudinally slidable interlocking sections which completely surround and insulate the electrode wire but can be assembled to the wire without disturbing its ends.
Claims7
A method of protecting an installed electrostatic precipitator discharge electrode wire from power arc erosion adjacent its lower end comprising the step of placing a plastic insulating shroud completely around the wire along the length of the wire subject to power arc erosion.
A shroud assembly for protecting an installed electrostatic precipitator discharge electrode wire from power arc erosion comprising a pair of first and second elongated plastic insulating members, each of said members including a longitudinal slot on one edge having a depth greater than the diameter of an electrode wire with which the member is adapted to be used, each of said members including a surface portion which is adapted to contact the surface of said wire and the second of said members having a portion having a transverse cross-sectional configuration which is complementary to the transverse cross-section of that portion of the slot in said first member which extends radially outwardly of said wire when installed thereon, each of said first and second members being adapted to be moved normally into contact with said wire at spaced locations along the length of said wire and then axially along said wire into overlying interlocking engagement with each other.
