新型扩散式下排气气固分离器的实验研究

Expermental Research on a New-Type Diffusible Gas-Solid Separator with Downward Exhaust Gas

通过实验方法 (分离效率的测定和三维粒子动态分析实验 )研究了扩散式下排气气固分离器的分离流阻 ,流场分布 ,分离效率等 ,从而达到降低扩散式气固分离器的阻力和提高分离效率的效果。分离器内部的各种设计 (如上导流锥高度的确定 ,下导流锥的倾角 ,排气管高度等 )均为提高气固分离器的效率和降低阻力。从实验可以看出 :该气固分离器对于 3 0 μm粒径的粗灰的分离效率很高 ,能达到 95 %以上。图 6参

The variation of the pressure drop, the fluid field and the separation efficiency of a new type diffusible gas solid separator with the downward exhaust gas under different operation conditions and the constructional details are experimentally investigated. The pressure drop and the velocity distribution in the separators are analyzed in order to decrease the pressure drop and increase separation efficiency. Figs 6 and refs 5.
