Chemical Random Tower packing 25mm Pall Ring Ceramic

Introduction

Pall ring is an advanced improvement of rasching ring, the walls of pall ring is open, height and diameter are the same and it has 4 diametrical ribs towards the inside of each "floor". Its structure improves distribution of gas-liquid and its efficiency can be improved above 50% and only has half of pressure drop compared with rasching ring.

Ceramic pall ring has excellent acid resistance and heat resistance. It 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 the application range is very wide. 

Application: It 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.

Advantage

1.These pall rings are made from chemical porcelain and have excellent resistance to acids except in the case of hydrofluoric acid.

 2. Moisture absorption must less than half a percent.

 3. The porcelain's specific gravity is 2.3-2.4g/cm3 and an average heat capacity (between 20ºC and 500ºC of 0.22 cal/g.ºC)

BAOAN ceramic raschig rings softening point is 1400ºC min. And they show good thermal shock resistance during repeated cycling between 20ºC and 820 ºC.
