Conjugate ring combines the advantages of ring and saddle packing, adopts conjugate curve fin structure, both ends of the outer fringed and appropriate length-diameter ratio, between the packing or the packing and the tower wall are point contact, no overlapping. The pores are uniform, the resistance is small, and the directional arrangement is taken when the pile is disorderly, so it has regular packing and characteristics. It has good fluid mechanics and mass transfer properties. It can be made of plastic, metal and ceramic.
