R&R-BETH dry electrostatic precipitators separate the finest dust particles from process air and exhaust gas streams with temperatures up to 420 ° C.
This filter technology is mainly used for hot gas dedusting of incineration plants or drying processes with hot gas application.
An artificial electrical charge is used to separate the finest dust particles from the exhaust gas stream.
A modular construction system, which includes different housing sizes, aisle spacings and delivery systems, enables the system size of the R&R-BETH dry electrostatic precipitators to be adapted to the process specifications of our customers.
This means that reliable cleaning of volume flows of up to 1,000,000 Bm3/h can be realised.
Innovative solutions enable us to safely 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 over the entire filter cross-section by gas distribution.
An electric field is built up by means of high voltage through the spray electrodes arranged between the precipitation plates and the dust particles are electrically charged. On their way through the electric field, the charged particles are transported by the electric field forces to the collecting electrodes, where they agglomerate with the already deposited dust particles and are cleaned by the rapping devices.
The knocked-off dust layer falls into the filter hopper and is discharged via the dust discharge. The cleaned gas leaves the filter through the gas outlet bonnet.
Precipitation and spray electrode rapping. The spray and collecting electrodes are cleaned by periodically acting, motor-driven rapping systems.
