Experimental Study on Dust Removal Performance …

for the particles above 5 µm can reach 99%, and the classification efficiency for
the particles above 10 µm is almost 100%. For fine particles, this dynamic wave
scrubber still has high classification efficiency.
3. The dynamic wave scrubber combined with a three-liquid-inlet nozzle has better
operating flexibility, high purification efficiency, and low-pressure drop. It is a
washing technology with great application prospects.
Variables
A
the axial liquid flow rate.
G
