Unit Operation
Operation
During normal operation, mist-laden air enters the
collector through a flexible hose. The air passes through
a disposable first-stage filter and into a second-stage
primary filter. Sub-micron mist particles are trapped and
retained as they coalesce and grow to large droplet size.
These filters are housed in a spinning, perforated drum
with internal radial fan blades to promote air movement.
The droplets are spun and thrown from the perforated
drum to the inner wall of the collector housing by
centrifugal force. High velocity air drives the liquid or
oil along the housing walls, through a circumferential
slot, and into a collection chamber where the liquid is
drained. A third-stage, secondary filter catches liquid
that bypasses the slot and drains through the secondary
drain. Clean air is exhausted through the fourth-stage,
exhaust grill filter and returned to the plant environment
while the recycled oil drains from the unit for reuse or
disposal.
