Vane electrostatic precipitator

摘要

The embodiments described herein improve on the present electrostatic precipitator method of using parallel plates to collect particulates by using multiple parallel vanes set at operating parameters described below. By using vanes, the main entrained air is subdivided and directed to flow between vanes that induce resistance to flow allowing charged particles to collect on the vanes. The width of the vane is designed to be wide enough so the air flow rate at the ends of the vanes is less than 1 ft/s, allowing particles discharged from the plates to fall by gravity and in the direction of very low air flow, resulting in extremely low re-entrainment and efficient particle collection. Using vanes also allows for higher operating air velocities resulting in a smaller equipment foot print.

1. A method for removing particles from at least one main narrow air stream, comprising the step of dividing the main air stream into at least two smaller individual air streams in a vane electrostatic precipitator comprising a plurality of opposing vane type collecting electrodes, wherein a leading edge of each vane type collecting electrode is offset from an adjacent leading edge such that each vane type collecting electrode is either longer or shorter than a preceding vane type collecting electrode.
