Dedusting plant for the asphalt mixing plant
In this RETROFIT project, an existing filter had to be replaced by a larger filter (expanded filter area) to fit the available space. Interfaces such as the connections of the expansion line and suction line of the paralell drum on the raw gas duct, the chimney fox, the on-site switch container as well as the main cable route of the asphalt mixing plant were taken over.
- Flat bag filter with large walk-in clean gas chamber
- Coarse separator
- Forcing flap
- Pipe augers
The raw gas is taken from the various emission sources and fed to the coarse separator via a pipeline. Below the coarse separator, the coarse dust fraction is transferred via a double pendulum flap into a tubular screw conveyor and transported to the hot elevator. The raw gas flows into the filter with the fine fraction and is cleaned at the filter pockets. The fines are also transported to a filler silo or filler tower via a double pendulum flap and tubular screw conveyor. The clean gas is then blown outdoors via the fan and the chimney.
