Electrostatic
precipitation removes particles from the exhaust gas stream of an
industrial process. Often the process involves combustion, but it can be
any industrial process that would otherwise emit particles to the
atmosphere. Six activities typically take place:
- Ionization - Charging of particles
- Migration - Transporting the charged particles to the collecting surfaces
- Collection - Precipitation of the charged particles onto the collecting surfaces
- Charge Dissipation - Neutralizing the charged particles on the collecting surfaces
- Particle Dislodging - Removing the particles from the collecting surface to the hopper
- Particle Removal - Conveying the particles from the hopper to a disposal point
