2. Air Pollution Control Devices
A________ tower
B__________
C____________ Separator
aD___________ Bed
E______________ precipitator
V___________ scrubber

3. Electrostatic Precipitator
w____ in t____ or wire and p____ configurations
wet or dry, wet cleaned by w______ s____, dry by rapping, can be cleaned while in service
c_______ wire imparts an electrical charge (neg), particles are attracted to charged (pos) collecting plates
high p__________ removal efficiencies possible

6. Venturi Scrubber
velocity of gas is a_________ by a factor of four in the throat section where nozzles inject water or solution
high velocity causes a__________ of liquid
pressure drop following the t________ section creates a lot of turbulence resulting in good intermixing
requires s_________ (e.g., cyclone) following venturi to collect particles and liquid

7. T___________ Incineration
