The shape of the ceramic pall ring aims to solve the shortcomings of the ceramic lasi ring in industrial applications, and the research and development of the ceramic pall ring has made great changes in the structure. His structure is based on a ring structure with eight small Windows on the outer walls of the ring to form eight tongues that bend inward to point at the center of the ring. There are two levels. The top and bottom window holes are reversed. In this way, the symmetry of the annular structure prevents the packing from reacting easily with other materials. Compared with the structure of the ring, the increased porosity changes greatly, which also improves the mass transfer function of the ceramic pall ring. The gas-liquid separation efficiency of the ceramic pall ring is greatly improved, the pores are evenly distributed, the efficiency is increased to one fifth, the pressure can be maintained relatively low, and the liquid does not follow the original path. Also, it is better to reduce the chances of container explosion and gas-liquid separation. Even when used in large containers, the working pressure of the ceramic pall ring packing may be much lower and more balanced than usual. The packing area and hole are too large for gas to pass through. The resistance is smaller and the quantity is much higher than before.

In practical chemical industry production, ceramic pall rings can be used in containers washed with acid liquid to filter out excess gas, so the concentration in the liquid is very high, and pall rings play an important role in ozone-related reactions. There are other types of containers, such as drying towers, some regeneration towers and cooling towers. Ceramic pall ring packing is used to obtain good mass transfer effect. In addition, ceramic itself has acid and alkali resistance, good corrosion resistance and high heat resistance, so that it is more and more widely used in paving tower.
