Abstract
An electrostatic precipitator is constructed with collecting and repelling electrodes. The collecting electrode is partially shielded from gas shear forces by a shielding structure. The shielding structure is mounted to reduce gas flow along a surface of the collector and includes passages for charged particles to travel to be captured by the collector.
Claims9
An electrostatic precipitator comprising:
- a housing with a housing cavity;
- one or more corona electrodes mounted in an air flow path in said housing;
- a plurality of first electrodes and a plurality of second electrodes mounted in said housing cavity, wherein said first electrodes are collector electrodes positioned generally parallel to an airflow path through said housing cavity;
- at least one perforated plate located parallel to one of said collector electrodes, wherein said perforated plate is spaced apart from said collector electrodes defining a gap between said perforated plate and said collector electrodes.

The electrostatic precipitator according to claim wherein said perforated plate is non-conductive.
An electrostatic collector assembly comprising:
- a conductive core;
- one or more perforated plates positioned adjacent to and spaced from said conductive core;
- and
- an airflow barrier between said conductive core and said one or more perforated plates arranged to block at least a portion of the airflow along a surface of said conductive core.
