EFFICIENCY AND PRESSURE LOSS IN APPARATUS WITH SWIRLING FLOW

Abstract

An apparatus is proposed that operates on the principle of gas purification from dust in counter swirling flows. The principle of operation of a dust collecting apparatus with swirling flows of gas suspensions is described. A differential particle size distribution curve is given. Studies of the efficiency of capture and determination of pressure losses in apparatuses with swirling flows are given. The factors influencing the work and cleaning efficiency are revealed. the results of a numerical calculation of the efficiency of trapping particles of various diameters in the VZP-200 apparatus are presented. Comparison of the calculated and experimental results shows the practical acceptability of the accepted movement of the gas and solid phases in dust collectors with counter swirling flows. A method for calculating the pressure in apparatuses with swirling flows is considered depending on various materials.
