Dust Collectors/Wet
Scrubbers
Wet scrubbers are an
economical and effective method for final cleansing of exhaust air to reduce
dust and odor emission before discharge to the atmosphere.
Evaporator Dryer
Technologies designs wet scrubbers for high efficiency dust collection, low
maintenance, water level control, low pressure drop and minimum water usage.
The scrubbers are available in a sanitary design and non-sanitary design that
can be cleaned (CIP) with the rest of the spray drying system.
In a spray drying system,
some dust particles (powder) in the air stream escapes collection in the
cyclone. A wet scrubber used in conjunction with a cyclone, will provide the
secondary cleaning of the air stream before discharge to the atmosphere.
The cleaning is accomplished
by spraying, or saturating the air stream with a liquid for final air
cleaning. Either product feed or water can be used as the scrubbing liquor to
entrain and recover the dust particles. By using product feed the wet scrubber
recovers what would otherwise be lost product.
