Ceramic Corrugated Structure Tower Packing & Ceramic Bellow Packing for Tower
Ceramic corrugated packing is a disk-type structured packing composed of corrugated ceramic sheets arranged parallel and vertically to each other. It features a compact structure and large specific surface area.
When the tower diameter is less than 450 mm, the packing is made as a whole disk. When the diameter is larger than 450 mm, it is fabricated in segments.
During operation, adjacent disks are stacked with a 90° staggered arrangement, so that liquid is redistributed and evenly distributed after passing each disk layer, which improves gas-liquid contact. Compared with conventional random packing, it can greatly reduce resistance and achieve higher operating efficiency.
Characteristic Parameters
① Ceramic corrugated packing has an operating temperature up to 500 ℃ and a bulk density of 500–1000 kg/m³. The commonly used sheet thickness varies: thicker sheets result in smaller specific surface area, while thinner sheets provide larger specific surface area, which is more favorable for separation or absorption.
② Corrugation peak height: standard dimensions are generally used. For processes with high liquid flow such as absorption and cooling, standard peak height is applicable. For applications requiring low pressure drop, such as vacuum operation, lower peak height can be used.
③ Corrugation pitch is generally about twice the peak height to ensure symmetrical corrugations; conventional corrugation pitches are widely used in industry.
④ Disk height: the disk height produced by our factory is generally 50 mm, and the maximum can reach 200 mm. Smaller disk height leads to more frequent redirection and better liquid redistribution, but makes installation more complicated.
⑤ Arrangement angle is generally 30–45 degrees.
