The furnaces are connected to Two-stage venturi scrubber systems to maintain a clean environment in and around the production area.
12.
Although small in size, these droplets are large compared to those created in venturi scrubbers that are 10 50 �m in size.
13.
Since efficiency of a venturi scrubber depends on pressure drop, some manufacturers supply a variable-throat venturi to maintain pressure drop with varying gas flows.
14.
On April 12, 1987, USEPA sampled an area of the Chemetco plant which was used to manage zinc oxide collected from the venturi scrubber system ."
15.
To obtain high efficiency removal of 1 micrometer ( or less ) particles generally requires high energy devices such as venturi scrubbers or augmented devices such as condensation scrubbers.
16.
All venturi scrubbers require an entrainment separator because the high velocity of gas through the scrubber will have a tendency to entrain the droplets with the outlet clean gas stream.
17.
Results of these findings led to the development of the annular-orifice, or adjustable-throat, venturi scrubber ( "'Figure 5 "').
18.
Cyclonic separators, the most popular for use with venturi scrubbers, are connected to the venturi vessel by a flooded elbow ( "'Figure 8 "').
19.
"' Figure 3 "'- Non-wetted throat venturi scrubber Simple venturis have fixed throat areas and cannot be used over a wide range of gas flow rates.
20.
"' Figure 7 "'- Venturi rod scrubber The primary maintenance problem for venturi scrubbers is wear, or abrasion, of the scrubber shell because of high gas velocities.
