A Experimental Formulae on Pressure of Small Cyclone Dust Separator

Abstract

This article is a report of our experiments regarding how much the pressure loss in cyclone dust separator may be changed by different proportions of the construction. In these experiments we have obserbed the influences on pressure loss by the different proportions of the main parts in the standard type of cyclone ; i. e. by the different cross-sectional areas of inlet slot, by the different diameters of exit pipe, by the different hights of cyclone body, and by the different lengths of exit pipe. The experimental formulae has become as follows : [numerical formula] Where Δp=total pressure loss in cyclone, u_i=linear speed in inlet slot, R=Reynold's number in inlet slot=[numerical formula], b×h=cross sectional area of inlet slot, D=diameter of cylindrical portion of cyclone body, d=inside diameter of exit pipe, H=effective length of cyclone body, l=length of exit pipe, r=specific weight of fluid gas, g=accelaration due to gravity.
