Dry Electrostatic Precipitators

The BETH Dry Electrostatic Precipitators are designed to significantly reduce dust emissions, achieving values below 20 mg/m³ (0.00873 grain/ft³) under standard conditions, well within legal limits. These systems offer numerous benefits over traditional media filtration systems, including:

The dust-laden process gas enters the electrostatic precipitator horizontally, where it is evenly distributed to create a consistent flow across the entire filter profile. High-voltage discharge electrodes generate an electric field that charges the dust particles as they pass through. These charged particles are attracted to the collecting electrodes, where they combine with already separated dust. The accumulated dust is dislodged by drop hammers and falls into the filter hopper for removal via the material discharge system. The purified gas is released out of the clean gas hood.
