Structural features of ceramic pall rings

Shape: Ceramic pall rings are annular packings with equal height and diameter, and are cylindrical.

Opening design: Each layer of window holes has 5 tongues, each tongue is bent inward and points to the center of the ring. The positions of the upper and lower layers of window holes are opposite and staggered. Generally, the opening area accounts for about 30% of the total area of the ring wall.

Performance advantages of ceramic pall rings

Good mechanical strength of ceramic pall rings: The ceramic material itself has high hardness and compressive strength, can withstand high pressure and friction, and is not easy to deform, break or wear, thereby extending the service life.

Ceramic pall rings have strong corrosion resistance: They can withstand corrosion from various inorganic acids, organic acids and organic solvents except hydrofluoric acid. When in contact with acids, alkalis, salts and various organic solvents, they can maintain stable chemical properties and will not rust or other chemical reactions.

Ceramic pall rings are resistant to high temperatures: They can be used in various high-temperature occasions, can withstand high temperatures, are not easily deformed or damaged by heat, and the maximum operating temperature can reach 1200℃, meeting the high-temperature requirements under various process conditions.

Ceramic pall rings have low fluid resistance: their unique structure allows gas and liquid to pass freely through the window holes, greatly reducing the resistance of the fluid passing through the packing layer, reducing pressure loss, and helping to improve the operating efficiency of the equipment and reduce energy consumption.

Ceramic pall rings have high mass transfer efficiency: the large specific surface area and uniform pore distribution provide sufficient contact area and good contact conditions for the gas-liquid two phases, promote the material exchange and mass transfer process between the gas-liquid two phases, and can accelerate the reaction rate and improve the separation effect
