Electrostatic Precipitator

摘要

An electrostatic precipitator may have different collecting and repelling electrodes surfaces. For example, a collecting electrode may have an internal conductive portion. A non-conductive or less conductive open cell foam covering may be applied to the conductive core of the collecting electrode. The foam may have cell sizes that vary within the volume of the foam or along the length of the foam. Accordingly the cell size of the foam near the leading, with respect to the direction of airflow, portion of the collector may be larger than the cell size of the foam nearer the trailing end of the collector and/or the cell size of the foam near the exterior of the collector may be larger than the cell size of the foam nearer to the interior of the collector.

主权项

1. An electrostatic precipitator, comprising:
an electrode assembly, wherein the electrode assembly includes a plurality of first electrodes and a plurality of second electrodes, wherein the first electrodes include an internal first conductive portion and an outer surface generally parallel with an airflow through a cavity of the electrode assembly; wherein the first electrodes further include a first portion comprising a porous open cell material, wherein the porous material has a length generally parallel with the airflow and a thickness generally orthogonal to the air flow, said porous material comprising cells that vary in size through the length of the first electrode.
