摘要
通过对气液旋流分离器分离性能的试验研究发现,排气管的结构尺寸对旋流器分离的临界速度及分离效率有显著影响。相对于传统的直管型排气结构,采用扩散锥形的排气管结构可以有效地削弱旋流分离器内短路流的影响,增大排气心管内液膜的形成速度,从而在保证压力降基本不变的前提下提高分离效率。旋流器分离的临界速度受物料含液浓度的影响不大,主要受排气管结构尺寸的影响。
Based on the separation experiments of gas-liquid cyclone separator, the style and the size of the exit tube had a strong effect on the critical velocity and separation efficiency of the cyclone separator. Compared with the conventional cylinder type of exit tube, the diffused cone type of exit tube could weaken the effect of short-circuit, prevent forming the liquid film in the exit tube, and the separation efficiency was increased without any change of the pressure drop in the cyclone separator. The critical velocity of the cyclone separator rests with not the consistence of the material, but the size of the geometry of gas outlet.
