Control Of Air Pollution Flashcards
Mechanical collectors
dust cyclones
multicyclones
From the air stream
Particulate control
A particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge
Highly efficient filtration devices that minimally impede the flow of gases through the device, and can easily remove fine particulates such as dust and smoke
Electrostatic precipitators (ESP) electrostatic air
cleaner
Designed to handle heavy dust loads
A dust collector consists of:
a blower,
dust filter,
a filter-cleaning system,
a dust receptacle or dust removal system
(distinguished from air cleaners which utilize disposable filters to remove the dust)
Baghouses
A variety of devices that use pollutants from a
furnace flue gas or from other gas streams
The polluted gas stream is brought into contact with the scrubbing liquid,
by spraying it with the liquid,
by forcing it through a pool of liquid,
by some other contact method, to remove the pollutants
