Ceramic Pall ring packing is a kind of open-hole packing with equal height and diameter. There are 5 tongues in each window hole, and each tongue is bent inwardly to the ring center. The positions of the upper and lower window holes are staggered oppositely, and the holes are generally open. The area accounts for about 30% of the total area of the ring wall. This structure improves the vapor-liquid distribution and makes full use of the inner surface of the ring, so that the gas and liquid in the packed tower can freely pass through the window.
