Electrostatic precipitators are cited as the most effective devices that are used for dust collection. The advantage of these devices operating in standard mode is:
- achieving lower values than those specified in emission requirements,
- low energy consumption, which results in high efficiency,
- sturdy structures
- individual customization,
- long service life,
- the maximum volume volume of flue gases introduced into the electrostatic precipitator up to 13,000 m3/h,
- jas well as low maintenance expenditures with favorable investment costs (limiting maintenance expenditures to one service per year).
The principle of electrostatic precipitators:
Dust-laden process gases enter the electrostatic precipitator horizontally. The distributed gas is evenly distributed over the entire surface of the filter at an equal rate. Using sparking electrodes located between the settling plates, an electric field is generated that electrically charges the dust particles. Passing through an electric field, charged particles are transported by field forces to settling electrodes, where they are sintered with already separated particles and subjected to purification in mechanical shaking facilities. The dust layer thus shaken off falls into the filter tray and is discharged through the dust outlet. The purified gas leaves the filter through the gas outlet shell.
Inside the channels in which the gas flows, there are atomizing frames with steel strip blade electrodes, centrally located. Depending on the type, the channels can have different spacing, which guarantees great flexibility of application.
In addition, there are backfill systems to choose from:
- screw winnower with cell lock,
- ash hopper,
- feeding auger,
- ash tank with vacuum cleaner,
- chain trough conveyor,
- chain and tube conveyor,
- oblique auger.
Compared to filter separators, Beth's electrostatic precipitators have very low energy costs due to the state-of-the-art WN control technology. These devices exhibit exceptional filtration properties.
Beth presents a range of dry electrostatic precipitators, which are used in thermal waste incineration processes, as well as wet electrostatic precipitators for combustion in biomass furnaces.
