Audited Supplier Absorber tower packing ceramic pall ring :
Ceramic Pall Ring is a kind of random packing with two layers of windows opened along its tube wall. The outside diameter is equal to its height. For each layer, there are 3 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 rings inner surface to improve distribution of vapor-liquid.
The packing can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers and actifier columns in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.
