Electrostatic Precepitators

An electrostatic precipitator is a device that removes particulate matters from the gas stream, typically in the form of smoke after combustion occurs. Also in many industrial plants, particulate matter created in the industrial process are carried as dust in the hot exhaust gases.

An electrical charge is imparted to the particles, causing them to adhere to metal plates inside the precipitator. Finally, tapping the plates causes the particles to fall in to a bin for disposal. Within an electrostatic precipitator are collection plates or tubes charged with negative voltage, which dry harvest particulate and dust from polluted air, smoke and gases.

Wet electrostatic precipitators use wet scrubber action while keeping a negative voltage charge. At Enviropol, industrial and consumer models are available.

Electrostatic precipitators are an advantageous choice for pollution control if:

  • Particulate matters are having moderate electrical resitivity.
  • Particulate matters are not sticky.
  • Gas stream is not explosive.
  • Process demands recovery of perticulates in dry condition.
