17%~23% Alumina Ceramic Pall Ring as Tower Packing
We Pingxiang chemshun ceramics co.,ltd specialize in produce all types of chemical tower packings. Ceramic pall rings is one of our regular ceramic packings.
1. Ceramic Pall Ring (Pall Ring in Ceramic)
Ceramic Pall Ring is one of the most common and well known tower packings. pall ring in ceramic is already an industry standard design media developed from the raschig ring and is used widely in all variety of applications. after improving, pall ring ceramic opens two rows of window holes with 5inners tongue sheet on wall of ring. this new structure improves distribution of gas and liquid, adopting inner surface of ring sufficiently. compared to rasching ring, its disposal capacity increases by up to 50% while pressure decreases to half of former.
Generally, the area for open windows occupies 30% of the total area of the tube wall. Ceramic Pall Ring helps vapor and liquid flow freely through these windows, making full use of the ring's inner surface to improve distribution of vapor-liquid.
Ceramic Pall Ring very popular ceramic random packings, Ceramic Pall Rings are originated by the improvement of ceramic raschig ring. ceramic pall ring is a open-hole ring packing that the height and diameter is same and with 5 ligules toward inside at every floor. usually, the open surface is 30% of the whole wall surface, pall rings' character helps the liquid and gas pass in packing tower pass freely from the windows of the rings. the pall ring open structures effectuate separation of gas and liquid streams and facilitate a more effective mass transfer. and decrease the pressure drop. chemshun ceramics is one of the main manufacturer, supplier, exporter for ceramic pall ring column packing.
