Principles of electrofilters

The electrostatic precipitators offered by ELENERGY consist of two main parts: a collection chamber and a DC-powered high voltage unit. The key elements of the precipitators - collecting and discharge electrodes – are located within the collection chamber. Collecting electrodes provide the surface area for dust settling, while discharge electrodes are powered by high voltage DC generator (aggregate). Charging of dust particles under the influence of ions takes place due to the electrical corona phenomenon. It occurs when the critical voltage characteristic for given multiple electrode systems is exceeded. Charged solid particles suspended in the gas flowing through the electrostatic precipitator’s chamber travel towards the oppositely charged collecting electrode. After contact with its surface, the electrostatic charge is transferred to the electrode and under the influence of gravitational and mechanical forces, dust particles fall into the dust chamber, from where they are removed automatically with the use of screw conveyor.
