【摘要】 三级 PV型旋风分离器是通过优化匹配组合 ,在给定压降下达到高效率的。大型冷模对比试验证实 :三级 PV型旋风分离器的分离性能及操作弹性均优于从国外引进的三级旋风分离器。在丙烯腈反应器内的工业应用证明 :吨丙烯腈催化剂的单耗已降低到 0 .3 7kg,旋风分离器的总压降可控制在 7k Pa以内 ,效果显著更多还原

【Abstract】 The high efficiency of third stage PV type cyclone is obtained by mean of optimagation grouping or regrouping,and under the condition of given pressure drop.Large scale cold model testing proves that:All the separation performance and operational flexibility of third stage PV type cyclones are better than that third stage cyclones imported from foreeign countries. The industrial application on the acrylonitrle reactors proves ththat:the unit catalyst consume of acrylonitrile per ton is decreased to 0.37kg.The total pressure drop of cyclone may be control in 7kPa.The effectiveness is excellent and this cyclone can be spreaded.更多还原
