The two stage vertical vane separator is used to remove contamination from gas streams. And, are particularly useful in applications where flow rates vary greatly.
Why Two Stage Vertical Vane Separator?
1. The first stage removes the bulk of the liquid before passing through the vane.
2. Efficiency remains flat from rated capacity to about 25% of flow (10 microns and above).
3. Pressure drop is very low (6” of H2O).
4. Vane design minimizes possibility of clogging.
PRINCIPLES OF OPERATION
1. The gas stream enters the vessel and is diverted by the baffle assembly.
2. The gas flows in a circular pattern and centrifugal force cause the heavy droplets to attach to the vessel walls, or fall out of the stream.
3. The gas then flows upward, away from the sump and through the vane (the vane is a labyrinth of passages that causes further impingement of droplets to clean the gas).
4. The accumulated liquids are drained through the drain pipe, down to the sump.
The vane is designed to create a repeated change of direction in the gas flow. The droplets, being heavier, cannot follow the flow as they impinge on the vane segments and drain off.
Competitive designs do not generally provide two stage separation. Use of the two-stage process increases the efficiency of the unit, and the possibility of carry-over is significantly minimized.
TM Filtration vane separators direct the gas up and out and the contaminant flow downward.
