Electrostatic Precipitators

Time to Read: 1m 55s

Electrostatic precipitators, or ESPs, are electronic filtration devices designed to remove fine particulates from a gas flow via an induced electrostatic charge (hence the name). These devices can remove dust, smoke, and other microscopic pollutants, and are generally used to treat gas flows used in industrial processing, or exhaust gases produced by such processing.

Operation

Basic ESPs consist of a row or rows of thin, vertical, electrified wires in parallel alignment with a flat, metal, grounded plate or plates. Wire and plate spacing varies depending on the application. The gas flow travels forward (horizontal
