Method for PTFE pall ring

- Jun 12, 2019-

The filler is the core component of the packed tower and is divided into structured packing and bulk packing. At present, the most widely used bulk filler in China's industry is the ring-shaped saddle filler. This kind of filler combines the advantages of large capacity of ring packing and good liquid distribution performance and is widely used in industrial production. However, due to its limited configuration, its specific surface area is small, there are not many leaching points, and its production capacity and mass transfer effect are still limited.

 

The purpose is to PTFE pall ring with high porosity, small pressure drop of the packing, high mass transfer efficiency and strong anti-blocking ability. The technical proposal of the utility model is: a Pall ring packing, which is composed of a Pall ring body, wherein the body of the Pall ring has a cylindrical shape, and the circumference of the body of the Pall ring is arranged at a vertical interval. A plurality of through holes are arranged in a staggered manner between the upper and lower through holes, and each of the through holes is provided with an arcuate tongue extending to the hole in the body of the Pall ring. The through hole is rectangular. The height of the Pall ring body is 40 mm; the diameter of the Bower ring body is 38-40 mm. The utility model has the advantages that the Pall ring packing can pass the curved tongue extending to the hole in the body of the Pall ring, and the liquid can be divided into several small liquid streams during the working process, thereby increasing the liquid in the packing. The spray point increases the gas-liquid contact area and improves the mass transfer efficiency. The existing filler is avoided due to the configuration limitation, so that the specific surface area is small, the liquid droplet point is not much, and the production capacity and mass transfer effect are still limited. The Pall ring packing has the characteristics of simple structure and low production cost, and is particularly suitable for installation of towers in industries such as refining, petrochemical, chemical and environmental protection.www.yihaoptfe.com
