Dry Electrostatic Precipitator

The VAPOUR Dry Electro-Static Precipitator (ESP) is a highly efficient separator that accomplishes minimal operating costs and maximized separation efficiency of around 99%.

 

An Electro-Static Precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

 

In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of electricity).

 

In the VAPOUR Dry Electrostatic Precipitator a high-voltage field of nearly 70 kV is created by discharge electrodes. In this zone, the free electrons are highly accelerated. This ionization is associated corona. This corona discharge generates gas ions which adhere to the dust particles and impart an electrical charge to them.

 

The charged particles then move into the separating chamber and transported between the discharge and collecting electrodes to the positively charged collection electrodes, and thus removed from the gas stream.

 

The separated particles form a layer on the collecting electrodes. Rapping system is used to remove these dust particles from both the collecting plates and the discharge electrodes. The dust particles fall into the hoppers.
