Electrostatic separation is done by initially charging the particulates or contaminants and then moving and concentrating them at the electric field boundary. Electrical separation was first demonstrated by Hohlfield in 1824 by clearing a smoked-filled jar with an electrified point.

How does an electrostatic smoke precipitator work?

Sep 25, 2019· How an electrostatic smoke precipitator works. Electrostatic smoke precipitators work by forcing dirty flue gas (the gas escaping from a smokestack) past two electrodes (electrical terminals), which take the form of metal wires, bars, or plates inside a pipe or smokestack. The first electrode is charged to a very high negative voltage.As the dirt particles move past it, they pick up a negative ...
