As a major type of tower packing, ceramic corrugated packing is widely applied in equipment such as rectification towers, absorption towers, extraction towers, heat exchangers and mist eliminators for industrial processes in the petrochemical, fine chemical and environmental engineering industries.
Since their advent, ceramic packing has developed rapidly due to its advantages of corrosion resistance and low cost, and new types of ceramic packing have been continuously developed. Ceramic corrugated packing is a new type of structured packing that has been widely used in recent years. As a kind of structured packing, it is fired from ceramic corrugated plates.
The specific surface area of ceramic structured corrugated packing is larger than that of random packing, with an increase of more than 15%.
The wettability of the ceramic corrugated packing surface is improved, which increases the wetted specific surface area of the packing, thereby raising the interfacial area and mass transfer efficiency. It intensifies gas-liquid disturbance and accelerates liquid surface renewal rate.
Geometric characteristic data include tray diameter, tray height, peak height, wave pitch, wave length, tooth angle, corrugation inclination angle and bulk density, which are the basic parameters reflecting the geometric characteristics such as the specification and shape of the packing.
