The CLAIR Electrostatic Precipitator is versatile and has a variety of applications across industries — in India and overseas. The EP process principally consists of three fundamental steps:

• Particle charging
•  Particle collection
• Removal of the collected dust

Particle charging in practical precipitators is accomplished by means of corona, which produces ions that become attached to the particles.

Generation of a corona requires the development of a highly non-uniform electric field – a condition that occurs near the electrode when a high voltage is applied to the emitting electrodes. The electric field near the emitting electrode accelerates electrons present in the gas to velocities sufficient to cause ionization of the gas in the region near the electrode.

The ions produced as a result of the corona migrate toward the collection electrodes and in the process collide with and become attached to particles suspended in the gas stream. The attachment of ions results in the build-up of an electric charge, the magnitude of which is determined by the number of ions attached.

The charge on the particles in the presence of an electric field results in a new force in the direction of the collecting electrodes. The magnitude of the force is dependent upon the charge and the field. This force causes particles to be deposited on the collecting electrodes where they are held by a combination of mechanical, electrical and molecular forces.

Physical arrangement of precipitators differs depending upon the type of application. Various types of emitting electrodes are used in precipitators. However, for reasons of space economy, most commercial precipitators use plates as collection electrodes.
