4、al Group,Datong Shanxi 037000 Abstract:In order to compare and analyze the separation effects of three cone hydrocyclone and single cone hydrocyclone,this paper takesthree cone hydrocyclone as the research object,and uses CFD numerical simulation method to compare the particle behavior and separatio
5、neffects of the two hydrocyclones.It is found that the internal stress distribution of single cone hydrocyclone and three cone hydrocyclone isalmost similar,but there are some differences in tangential and axial velocity.The difference between the maximum tangential velocity andthe minimum tangentia
6、l velocity of the three cone hydrocyclone is large,and the centrifugal force of separation is large.The axial velocity ofthe three cone hydrocyclone is significantly greater than that of the single cone hydrocyclone,which is conducive to the discharge ofseparation materials.At the same time,the processing capacity of the three cone hydrocyclone is greater,so in general,the separationefficiency ofthe three cone hydrocyclone is better.Key words:three vertebral cyclones;single cone cyclones;numerical simulation;tangential velocity;stress distribution;axial velocity 39
