As a classic filler in scrubbers, ceramic raschig rings have been used in chemical and environmental protection fields for a long time due to their corrosion resistance, mechanical strength and cost advantages. However, under the demand for modern efficient separation, limitations such as low mass transfer efficiency and easy blockage have gradually been exposed. The following analyzes its characteristics, applications, advantages and disadvantages and development trends:

Basic characteristics of ceramic raschig ring

Material and structure

The ceramic raschig ring is made of acid-resistant ceramics such as high alumina and corundum. It has a height and diameter equal to that, forming a simple cylindrical ring structure.

The surface is smooth and the porosity is high, but traditional designs lead to limited gas-liquid contact efficiency.

Corrosion resistance

It can withstand corrosion of a variety of inorganic acids, organic acids and organic solvents except hydrofluoric acid, and is suitable for the washing process of highly corrosive gases or liquids.

High temperature resistance

It can be used for a long time in high-temperature environments (such as above 1200℃), and is suitable for high-temperature flue gas desulfurization, denitrification and other processes.
