Zhongci - Ceramic Pall Ring Tower Packing

Pall rings are an upgraded version of the ceramic Raschig ring design with good mechanical strength and a non-porous surface. It is generally cylindrical in shape, with open walls and inwardly curved tabs, and has the characteristics of high temperature and high pressure resistance, low water absorption, and stable chemical properties. In general, the opening area accounts for 30% of the total area of the cylinder wall. Facilitating the free flow of vapor and liquid through these windows, surface area is maximized while minimizing profile, utilizing the inner surface of the ring to improve vapor and liquid distribution. Allows the free flow of gases and liquids while greatly reducing the potential for entrainment. Separation efficiency can also be improved.

Ceramic Pall Ring is improved from the ceramic Raschig Ring, Ceramic Pall Ring has add a design of open the holes for the weeks wall, this construction can improve the surface area and voidage, Ceramic Pall Ring makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressure drop than ceramic rasching ring.

Ceramic Pall Ring with excellent acid resistance and heat resistance. They can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions. Consequently their application ranges are very wide. Ceramic Pall Ring can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industry, etc.

Ceramic Pall ring is the advanced products of ceramic Raschig ring. Compared with ceramic Raschig ring, there are two layers of window on the cylinder wall. And each layer has five ligules bending inward.

This design makes the surface area and voidage be improved and the porosity be evenly distributed. Additional, it has greater capacity and lower pressure drop than ceramic raschig ring.

• Excellent heat and acid resistance.
• Higher capacity.
• Lower pressure drop.
• Evenly distributed porosity and fluid.

• Ceramic pall ring can be used in high or low temperature conditions.
• It can be used in the drying columns, absorbing columns, cooling towers, scrubbing towers in chemical industry, metallurgy industry, coal gas industry, oxygen producing industries, etc.
