Gas phase pressure drop characteristics in a water-sparged aerocyclone
摘要
Abstract
Water-sparged aerocyclone (WSA) is a new type of gas-liquid mass transfer equipment with high efficiency. The gas phase pressure drop characteristics in WSA was investigated in this study. With the increase of inlet gas velocity (wg), the liquid jet presents three patterns: steady-state jet, deformed spiral jet and atomized spiral jet, and the pressure drop curves in WSA can be divided into three different regions, I.e. ? Low pressure drop, abruptly increased pressure drop and high pressure drop. In the low pressure drop region, the liquid holdup in outlet gas (eL) is almost zero, and the gas pressure drop in WSA (.Ap) increases with ut. In the second region, sL develops from zero and Ap increases abruptly. In the high pressure drop region, eL and Ap increase with ?g. The mechanism of the three pressure drop regions is discussed. A non-dimensional empirical model is developed for the regions with low and high pressure drop, which correlates the Euler number with the gas Reynolds number based on the available experimental data and can be well used to predict the pressure drop in WSA.关键词
