Experimental Study on Dust Removal
Performance of Dynamic Wave Scrubber
for Smelting Flue Gas
Fang Dong, Yan Liu, Xiao-long Li, Gui-li Liu, and Ting-an Zhang
Abstract In order to efficiently remove the fine particles in the smelting flue gas,
especially PM2.5, this paper designed and built a dynamic wave scrubber dust
removal device. Through the optimization of equipment, nozzle structure, and operating conditions (liquid–gas flow rate ratio, dust mass concentration), the final dust
removal efficiency has been achieved. The effects of liquid–gas flow rate ratio, gas–
liquid flow pattern, dust mass concentration on the dust removal efficiency were
studied. The results show that the dust removal efficiency increases with the increase
of liquid–gas flow rate ratio and initial dust mass concentration. When the foam
flow pattern is formed in the washing zone, the performance of the dynamic wave
scrubber is better than its performance when forming other flow patterns. The total
dust removal efficiency can be more than 99%, the classification efficiency of PM2.5,
the particles above 5 µm, and the particles above 10 µm are more than 98.35%, 99%,
and almost 100%, respectively, when the liquid–gas volume ratio is more than 0.004.
