通过理论分析及工程经验对石灰石/石膏法烟气脱硫工艺中石膏浆液脱水系统的旋流器进行优化设计,在与工业实际相近的操作条件下,优选出了一根综合性能较好的旋流器.考察了该旋流器的压力、流量与分离效率之间相互关系,与常规石膏浆液旋流器的分级效率进行了比较,确定了最佳操作条件.结果表明,旋流器的进口流量随着进出口压力差的增大而增大,分离效率随着流量增加先上升后下降.在进口硫石膏颗粒平均粒径为24μm,流量为11.8～14.8 m~3/h时,分离效率在85%以上,底流出口10μm、15μm以下的颗粒分别占底流出口颗粒总体积的1%、10%左右,起到了很明显的分级浓缩作用,分离性能也优于常规使用的石膏浆液旋流器.

Optimization design was carried out on dewatering of gypsum slurry hydrocyclone based on the theoretical calculations and engineering experience. A well separation performance hydrocyclone under the simi-lar conditions of industrial operation was selected. The relationship of pressure,inlet flow rate and separation effi-ciency of the hydrocyclone were studied. The grade efficiency was compared with normal hydrocyclone. Pressure drop increased with inlet flow rate increasing, while separation efficiency increasing firstly, and then decreased. Under the condition that inlet flow rate is ranging from 11. 8 to 14. 8 rri3/h and the average diameter of gypsum particles at inlet is 24 μm, the separation efficiency is higher than 85% . The particle size less than 10 μm and 15 μm account for 1% and 10% at underflow outlet. The hydrocyclone plays a great role in classifying and thicken-ing. Also the separation efficiency is better than normal hydrocyclone.
