Experimental study of hydrodynamics in a vortex contact apparatus

Abstract

The outcomes of experimental investigations into ascertaining the hydraulic resistance of a vortex apparatus, featuring swirling gas and liquid flows under diverse design and operational conditions, are showcased. These examinations on pressure loss in vortex-type apparatuses facilitate the estimation of energy consumption for activities such as dust removal, contact heat exchange, gas absorption purification, and other processes conducted within gas-liquid systems. Notably, it has been observed that the hydraulic resistance of the scrutinized vortex apparatus is markedly lower compared to the pressure drop encountered in nozzle-type and plate-type apparatuses. Furthermore, it does not surpass the resistance exhibited by high-efficiency vortex-type apparatuses of alternative designs. The hydraulic resistance of hollow vortex apparatuses, equipped with tangential swirlers, is contingent upon variables such as gas phase velocity, liquid flow rate, apparatus design parameters, and the physical properties of the working media. Through the meticulous analysis of experimental data, calculation dependencies have been derived to determine the resistance coefficients of both dry and irrigated vortex apparatuses. These dependencies prove to be practical and convenient from an applied standpoint.
