THE AIRWASHER- HOW IT WORKS
The dyers are vented to inlets (arranged per your order) on the upper half of the AIRWASHER. Immediately
below each inlet is a “target spray outlet”. Re -circulated water is pumped through a manifold under pressure
to the spray pipes, each a full ¼’ fully open. The water discharged from each pipe shoots at a “target” which
disperses –splatters- the water up into the air stream of the dryer exhaust. The dryer exhaust passes
through the water spray twice, as the water is splattered up, and as the water splashes down again,
resulting in higher efficiency lint removal.
Immediately opposite the inlets is a curved baffle. This baffle turns the exhaust air, now full of wet lint, down
into the conical bottom half.
The conical bottom is dimensioned to provide space to slow the exhaust below the velocity at which wet lint
transported, so the wet lint tends to fall out of the air stream.
A tubular exhaust fan located on top of the AIRWASHER draws the exhaust up, out of the conical bottom
through a space where the velocity is slowed still further. The AIRWASHER exhaust fan is sized to
overcome the resistance to the airflow through the AIRWASHER; the dyer fans are responsible for
overcoming the resistance in the dryer exhaust ducts.
The wet lint, being heavier than the air it displaces, tends to fall. The wet lint then impinges on the baffle
and on the interior surfaces of the AIRWASHER. Water from the “target sprays” floods the entire interior
and is washed down and out the bottom drain.
In the sump there are separation screens, which remove most of the lint from the water, so the water can be
recirculated. There is a float assembly connected to your water supply to replace that quantity of water
entrained in the air stream leaving the AIRWASHER.
The AIRWASHER may optionally include one barometric damper, to stabilize the negative pressure at the
collector inlets regardless of the number of dryers operating. The barometric damper works like a one-way
air valve between the atmosphere and inside the AIRWASHER, allowing air to rush into the AIRWASHER
from atmosphere when dryers turn off, thereby preventing excessive vacuum on the dryers that remain
operating. The barometric damper swings passively on a single hinge, and is maintenance free.
