For the cyclone separation technology, the cyclone separation method is difficult to separate the dispersed phase with small size, the particle size distribution of the dispersed phase is one of the important factors determining the cyclone separation efficiency, in practical application, the phenomena of good separation effect of large-particle-size droplets and poor separation effect of small-particle-size droplets often occur, and the part of droplets with smaller particle size directly flow out from the continuous phase outlet along with the continuous phase without separation, thereby causing certain influence on the separation effect.

If the efficient separation of the small-particle-size dispersion phase is to be realized, the small-particle-size droplets need to be guided to the center of the cyclone in the cyclone separation process, so that the centrifugal force applied to the small-particle-size dispersion phase is increased. Therefore, the research of the cyclone separator capable of improving the separation efficiency of the small-particle-size dispersed phase has great significance for petroleum, chemical industry and related industries.
