Abstract
A vane electrostatic precipitator (VEP) controls the air flow so that the entrained air particles are continuously subjected to a stress in the form of drag as they flow in front and behind vanes electrodes in the precipitator. It is not based on achieving laminar air flow over the collecting plates. Instead, efficient collection is achieved by operating with a narrow air stream and using vane electrodes in various configurations with porous back plates that gradually reduce the flow rate of the entrained air thereby allowing the particles to precipitate and collect on the vanes.
Claims29
A method for removing particles from a single narrow air stream, comprising the step of passing the narrow air stream over a plurality of opposing rotatable vane type collecting electrodes each having a leading edge and a plurality of discharge electrodes centrally located between the leading edges of the vane type collecting electrodes in a vane electrostatic precipitator, wherein the plurality of vane type collecting electrodes are located at ground potential such that there is an electrical field established between a leading edge of the vane type collecting electrodes and the discharge electrodes and no electrical field between opposing vane surfaces.
A method of collecting a plurality of particulates, comprising the step of collecting the particulates using a vane electrostatic precipitator comprising a combination of rotatable vane type electrodes located at ground potential and each having a leading edge, and a plurality of discharge electrodes centrally located between the leading edges of the vane electrodes such that there is an electrical field established between a leading edge of the vane electrodes and the discharge electrodes and no electrical field between opposing vane surfaces.
An electrostatic precipitator comprising a plurality of rotatable vanes located at ground potential and each having a leading edge, and a plurality of discharge electrodes centrally located between the leading edges of the vanes, wherein there is an electrical field established between a leading edge of the vanes and the discharge electrodes and no electrical field between opposing vane surfaces.
