Pollution Control Systems

The ELECTROSTATIC PRECIPITATOR PLANT is an electrical system for separation of the solid and liquid suspended particles from gases and vapors under the effect of electrical fields.
In a part of the precipitator plant, the suspended particles are electrically charged and then separated. This section consists mainly of the precipitator casing with a built in electrode system and the internal equipment.
Principles of the process:
The gases to be cleaned pass through the precipitator casing. The internal equipment of the precipitator consists mainly of high voltage carrying discharge electrodes (DE – negative pole) and the cathode collecting electrodes (CE – positive pole) which are arranged opposite the discharge
electrodes.

Discharge Electrodes

Discharge Electrodes

The discharge electrode (wires) are on high voltage and due to the direct current, the gas molecules are ionized. Thus the negative discharge is created. The dust and mist particles are attracted by the earthen collecting electrodes due to electrostatic field created simultaneously between the collecting and discharge electrodes. The particles are separated from the gas flow at the collecting.
The precipitated dust is periodically dislodged from the collecting electrodes by means of the rapping system with hammers. The dust then drops into the collecting hopper and is extracted by dust discharge elements.
