Dry Electrostatic Precipitator

An ESP uses a high voltage electrostatic field to separate dust, fume or mist from a gas
stream. The precipitator consists of vertical parallel plates (collecting plateselectrodes)
forming gas passages 12 to 16 in. (30.5 to 40.6 cm) apart. Discharge electrodes are
electrically isolated from the plates and suspended in rows between the gas passages.Every particle either has or can be given a charge - positive or negative. A high voltage system provides power to the discharge electrode to generate an electrical field. The
particulate, entrained in the gas, is charged while passing through the electrical field. The
particulate is then attracted to the grounded collector plate, and forms a dust layer on the
plate.
