The addition of flanging not only increases the mechanical strength of the packing ring, but also destroys the symmetry of the packing structure, thereby increasing the orientation probability of the packing when it is put in. Also due to the influence of the flanging, the gap between the packing ring and the packing ring is increased when the packing is accumulated. The contact between them has changed from mainly linear contact to mainly point contact. In this way, it not only increases the gaps between the filler particles and reduces the resistance of gas passing through the filler layer, but these contact points can also serve as liquid along the filler surface. The convergence and dispersion points of the flow promote the surface renewal of the liquid film and are conducive to the improvement of the mass transfer efficiency of the packing.
The height-to-diameter ratio of Qiancheng brand stepped ring packing is only that of the Pall ring half of the ring, and a tapered flange is added to one end of the ring, which reduces the resistance of the gas passing through the bed and increases the flux. The strength of the filler is also higher. Due to its structural characteristics, the space between the fillers in the filler layer is Most of them are in point contact. This not only increases the void ratio and reduces the pressure drop, but also forms a gathering or dispersion point for the liquid to flow along the packing surface, which promotes the renewal of the liquid film surface and the mixing of the liquid, so that the gas and liquid are evenly distributed and increases the It improves the mass transfer efficiency by reducing the gas-liquid contact surface. It is generally made of plastics, ceramics, and metals. Different materials have different structures. The internal rib structure of the metal ladder ring is the same as that of the Pall ring, and the tongue is bent in a blade shape; plastic The inner rib structure of the porcelain step ring is similar to that of the plastic Pall ring, and can also be divided into rice-shaped and tic-shaped.
