Several Common Types of Ceramic Packing
Ceramic packing, also known as ceramic rings, features excellent acid and heat resistance and is resistant to corrosion by various acids and alkalis except hydrofluoric acid. It boasts a wide range of applications and can be used as the lining of scrubbing towers, cooling towers, recovery and regeneration towers, desulfurization towers, drying towers, absorption towers and reactors in industries such as chemical engineering, metallurgy, acid manufacturing, coal gas, oxygen production, iron and steel, pharmaceutical manufacturing and fine chemical engineering.
There are dozens of ceramic packing products including ceramic Raschig rings, ceramic Pall rings, ceramic cascade mini-rings, ceramic intalox saddles and ceramic corrugated packing. Several key products are highly recommended as follows:
Ceramic Pall Rings
Ceramic Pall ring packing is a kind of perforated ring packing with equal height and diameter. Each layer of window holes is equipped with 5 tongue leaves that bend inward toward the ring center, and the window holes of the upper and lower layers are staggered in opposite positions. Generally, the open area accounts for about 30% of the total area of the ring wall. The structure of Pall rings optimizes gas-liquid distribution and makes full use of the inner surface of the rings, allowing gas and liquid in the packed tower to pass freely through the window openings.
Ceramic Intalox Saddles
Ceramic intalox saddle packing is a new type of packing improved on the basis of ceramic super intalox saddles, with the smooth arc sides of the latter replaced by serrated or raised textured sides. This design increases the contact gaps between packing pieces in the packed bed, facilitating the flow and diffusion of gas and liquid in the packing layer.
Ceramic Cascade Mini-Rings
Ceramic cascade mini-ring packing is a new type of high-efficiency perforated ring packing, whose height is about half of its diameter. One side of the ring is with a conical flange, four high holes are evenly distributed on the ring wall, and a rice-shaped inner rib is installed inside the ring. The unique structural design ensures that the packing is stacked mainly by point contact, which not only increases the porosity of the packing and reduces air flow resistance, but also greatly improves the gas-liquid distribution performance in the packing layer.
Ceramic Raschig Rings
Ceramic Raschig rings are the earliest developed random packing with a simple structure, which are circular rings with equal height and diameter. Large-sized Raschig rings (over 100mm) are generally filled regularly by whole masonry, while those under 100mm are mostly filled by random stacking.
