摘　　要：蜗壳式旋风分离器作为轻烧镁旋流动态煅烧系统中最重要的分离设备,是提高系统分离性能的关键所在。文章建立蜗壳式旋风分离器分离性能试验装置,研究入口风速对阻力系数与压降的影响和颗粒浓度对分离效率与压降的影响。研究发现:蜗壳式旋风分离器的静压降随入口风速的增大而增大,静压降与入口风速平方成正比;压降随颗粒浓度增大而减少,分离效率随颗粒浓度的增大逐渐升高。The volute cyclone separator is the most important separation device in the calcined magnesium rotary dynamic calcination system,which is the key to improve the separation performance of the system.The separation performance test device of volute cyclone separator was established to study the influence of inlet wind speed on drag coefficient and pressure drop and the effect of particle concentration on separation efficiency and pressure drop.It was found that the static pressure drop of the volute cyclone increased with the increase of the inlet wind speed,and the static pressure drop was proportional to the square of the inlet wind speed.The pressure drop decreased with the increase of the particle concentration,and the separation efficiency was gradually increased with the increase of the particle concentration.
