dust removal argon rinsing stands / lead filter system
Use of TurboJetPulse filters with upstream TurboSpark spark separator for dust removal the argon rinsing stands and the slag dumping stand.
- Raw gas flaps
- Axial spin separator
- Pipe screw conveyor
- MSR components
- Pressure sensor and temperature sensors
- Filtration system
- Rotary valve
- Level sensors
The installed turbofilter plant is operated alternately. Behind the raw gas flap dedusting filter, a swirl separator is installed in the raw gas line directly at the filter inlet, which has the task of achieving pre-separation of the dust as well as elimination of the sparks.
The lead vapor dedusting is extracted by opening / switching over the electrically operated raw gas flap dedusting filter described above.
The dust accumulating via the filter hoppers and pneumatic gate valves is fed to a tubular chain conveyor by means of two filter screws assigned to the respective filter unit.
With the pipe chain conveyor, the dust is fed to a dust collection container (silo). From the silo, the dust enters a reversible screw conveyor via a manual gate valve. From there, the material is pumped into the Eirich mixer in normal operation or directly into the on-site container via a downpipe in emergency operation.
