CARBON FIBER COMPOSITE DISCHARGE ELECTRODE WITH MECHANICAL BIAS

摘要

A discharge electrode using carbon fibers, nanofibers and/or nanotubes to generate the corona discharge. The invention contemplates conductive fiber, such as carbon strands with or without a polymer matrix to form a composite, and a supporting configuration in which the strand is extended along or wrapped helically around a supporting rod that extends along the length of the electrode. A mechanical bias is applied to each strand to maintain tension on the strand. Preferably this includes coil springs extending between bushings mounted on the rod and moveable hemispherical supports slidably mounted on the rod that seat against the strand.

主权项

1. A discharge electrode for use in an electrostatic precipitator having a power supply connected to at least one collection electrode and a flow of gas and particles across the discharge electrode and the collection electrode, the discharge electrode comprising:
(a) a non-conductive rod extending into the flow of gas, the rod having a first end attached to a support structure and an opposing, second end that is cantilevered into the flow of gas; (b) a plurality of conductive fibers forming at least one strand that extends along at least one side of the rod and is exposed to the flow of gas, wherein said at least one strand is electrically connected to the power supply; and (c) a bias mounted to the rod at a first bias end and seated against said at least one strand at a second bias end, the bias thereby applying a longitudinal force to said at least one strand to maintain said at least one strand substantially taut along said at least one side of the rod.
