- Movement of charged dust particles towards the electrodes. (embodied by Coulomb forces)
- Charged dust particles are deposited on the electrodes.
Principle of the Coulomb Electrostatic Precipitator
Electrostatic precipitation technology is derived from Coulomb`s Law, the basic theory of electrostatics,??.png
- Coulombic force, i.e. the attractive force between the charged dust particles and the dust accumulation pole of the anode plate.
- distance between the charged dust particle and the dust accumulation pole of the anode plate.
- electrostatic force constant.
- q1, q2: amount of dust charge, amount of dust accumulation pole (anode plate) charge.
