Experimental Study and Analysis on Performance and Dedusting Efficiency of Frothing Generator

By simulating test and study in laboratory, the structure and performance of frothing generator were determined. The relative curves between the frothing volume and gas velocity of foaming net, supplying liquid volume and the content of foaming agent were obtained respectively. There were an optimum gas-velocity of foaming net, an optimum supplying liquid volume and an optimum content of foaming agent under the condition of the given material quality and shape of foaming net and spraying form. The spraying froth is of a great assistance in collecting respirable dust.
