Dry electrostatic precipitator

R&R-BETH® dry electrostatic precipitators separate the finest dust particles from process air and exhaust gas flows at temperatures of up to 420 °C. This filter technology is mainly used for hot gas dedusting of incineration plants or drying processes with hot gas application.
Artificial electrical charging separates the finest dust particles from the exhaust gas flow.

A modular system, which includes various housing sizes, aisle spacings and removal systems, enables the system size of the R&R-BETH® dry electrostatic precipitators to be adapted to the on-site process specifications of our customers.
This means that reliable cleaning of volume flows of up to 1,000,000 Bm³/h can be achieved.

Thanks to innovative solutions, we are able to reliably achieve clean gas values of 5 mg/m³ residual dust with the R&R-BETH® dry electrostatic precipitator systems.

Functional principle

The dust-laden process gas enters the electrostatic precipitator horizontally and is brought to a uniform flow profile across the entire filter cross-section by means of gas distribution.

The spray electrodes arranged between the collecting plates create an electric field using high voltage and charge the dust particles electrically. On their way through the electric field, the charged particles are transported to the collecting electrodes by the electric field forces, where they agglomerate with the already deposited dust particles and are cleaned by the knock-off devices.

The knocked-off dust layer falls into the filter hopper and is discharged via the dust outlet. The cleaned gas leaves the filter through the gas outlet hood.
