Filter system with dry sorption
GARANT-Filter supplied the extraction and exhaust gas treatment system. The purpose of this system is to separate the particles from the exhaust air stream and treat the toxic gaseous substances with the help of additives.
- Sewer system
- Filter system with mixing reactor
- Pre-separator with recirculation
- Storage and dosing unit for hydrated lime
- Activated carbon dosing unit
- Silo for residues
The resulting raw gas is extracted via the welded duct system at the transfer points. In the first stage, the raw gas flows through a pre-separator that works on the principle of a cyclone. This prevents sparks from being sucked in and the associated ignition hazard for the filter system. The injected additive reacts with the gaseous pollutants according to the principle of adsorption and absorption. The dust separated from the filter bags is discharged into big bags via mechanical screw conveyors and discharge sluices or, alternatively, into a residue silo via a pneumatic system.
