Annular Random Pile Ceramic Packing - Pall Ring

Ceramic Pall ring is a new type of high-efficiency packing that is improved on the basis of Laxi ring, because the window hole is opened in the side wall of the ring, the gas-liquid distribution of the packing layer is improved, and the inner surface area of the ring is fully utilized, and it has the characteristics of small resistance, uniform liquid distribution, less bias flow and large operation elasticity. Compared with the same specification of the Lassi ring, the flux of the Pall ring packing can be increased by 50%, and at the same gas speed, the pressure drop of the Pall ring packing is only half of the Lassie ring, so the Pall ring is still widely used at present.
