China Ceramic Pall Ring as Random Packing

Ceramic Pall Ring as Random Packing
1. Product Description
Ceramic pall ring is a kind of random packing further developed based on Rischig Ring, with two layers of windows opened along its tube wall. The outside diameter is equal to its height. For each layer, there are 5 ligules bending inward the axes of the ring. The open position for windows between the two layers is staggered oppositely. Generally, the area for open windows occupies 30% of the total area of the tube wall. It helps vapor and liquid flow freely through these windows, making full use of the ring's inner surface to improve distribution of vapor-liquid.

The Advantages of Ceramic Pall Ring
• Acid resistance
• High temperature resistance
• Anti-aging properties
• Resistant to various inorganic acids, organic acids and organic • solvents except hydrofluoric acid (HF)
• Can be used in various high and low temperature occasions

The Application of Ceramic Pall Ring
Ceramic pall ring is widely used in metallurgical, chemical, fertilizer, acid, gas, oxygen, pharmaceutical and other industries in washing towers, cooling towers, recycling acid towers, desulfurization towers, drying towers and absorption towers.

Material of Ceramic Raschig Ring
15-22% AL2O3 + 70% SiO2
The formula of ceramic could be adjusted according to the client's needs.
