And because of the influence of flanging, the contact between the ring gap of the packing changes from linear contact to point contact. In this way, not only the gap between the packing particles is increased, the resistance of gas through the packing layer is reduced, and these contact points can also be the convergence and dispersion points of liquid flow along the surface of the packing, thus promoting the surface renewal of the liquid film, which is conducive to the improvement of the mass transfer efficiency of the packing.

Specifications: With a diameter of 16mm, 25mm, 38mm, 50mm, 76mm

The height-to-diameter ratio of the stepped ring is only half that of the Bauer ring, and a conical flanging is added to one end of the ring, which reduces the resistance of the gas through the bed. With the increase of flux, the strength of the filler is also higher. Due to its structural characteristics, the point contact between the fillers in the filler layer is more. This not only increases the voidage, reduces the pressure drop, but also forms the collection or dispersion point of the liquid flow along the surface of the packing, promotes the liquid film surface renewal and liquid mixing, makes the gas-liquid distribution uniform, increases the gas-liquid contact surface and improves the mass transfer efficiency, generally made of plastic, ceramic and metal. The structure of the metal ladder ring is different from that of Pall ring, and the tongue is shaped like a blade. The internal reinforcement structure of the plastic and porcelain ladder ring is similar to that of the plastic Pall ring, and it is also divided into rice shape and well shape.
