摘要
为了研究气相流速和初始雾滴浓度对气液聚结分离器分离效果的影响规律,采用超声波雾化器来造雾,产生极微小的液滴,并通过重量法和湿法等动取样方法对气液聚结分离器含液率进行测量。实验结果表明,随着气流速率的增加,分离效率先显著增大,再保持较高水平。气液聚结分离器的压降也随气流速率增大逐渐增大,相关性接近正相关。初始雾滴浓度并非在所有的气流速率下,会对气液分离效率产生明显的影响。
In order to study the influence of gas phase flow rate and initial droplet concentration on the separation effect of gas-liquid coalescence separator,an ultrasonic atomizer was used to create fog and produce extremely small liquid drops,and the liquid content of the gas-liquid coalescence separator was measured by means of the gravimetric method and the wet isokinetic sampling method.The experimental results show that the separation efficiency increases significantly at first and then remains high with the increase of gas velocity.The pressure drop of the gas-liquid coalescence separator increases with the increase of gas velocity and the correlation is close to positive.The initial droplet concentration does not have an obvious influence on the gas-liquid separation efficiency at all gas velocities.
