分流型芯管开缝结构对导叶式旋风管分离性能的影响

摘要

Effects of slotted area ratio and position of vortex finder on pressure drop and separation efficiency of cyclone tube were analyzed. The results show that the slotted vortex finder can reduce cyclone tube pressure drop while separation efficieney rises; and the slotted area ratio increase can lower this pressure drop. Separation efficiency of over 5 μm particles is the highest while shotted area ratio reaches 3. 0. The slotted vortex finder with slots at its lower part can improve operational flexibility of the cyclone tube.%通过改变分流型芯管开缝面积比和开缝位置研究了开缝结构对旋风管压降和不同粒径颗粒分离效率的影响.结果表明,侧壁开缝的分流型芯管能够有效地降低旋风管的压降并且提高不同粒径颗粒的分离效率;随着开缝面积比增大,旋风管压降降低,开缝面积比为3.0使5μm以上颗粒分离效率最高;分流型芯管下部开缝能够提高旋风管的操作弹性.
