Advanced electrode design for electrostatic precipitators
The subject of this paper is a wavy electrode precipitator which employs a new collecting electrode. The wavy electrode precipitator incorporates a contoured collecting electrode geometry which produces a nearly uniform electric field along the electrode. This feature allows operation with higher average electric field strengths near the electrode than in conventional designs. The wavy electrode provides separated flow zones within its valleys, which fluid dynamically shield particles from the main stream. The design also provides mechanical rigidity to vertical bending without the sharp flanges normal to the flow commonly found in conventional precipitators. These features permit increased performance for all particle sizes, but especially help in the precipitation of fine particles which are normally the most difficult to collect.
