PTFE pall ring filler application range

- Nov 12, 2019-

It is suitable for use as a contact filler and other reaction towers for carbon dioxide degassing towers, ozone contact reaction towers, and the like. The Pall ring packing is an improvement to the Raschig ring. Two rows of rectangular holes are formed in the side wall of the Raschig ring. One side of the cut ring wall is still connected to the wall surface, and the other side is bent inside the ring. Forming an inwardly extending tongue, the sides of the tongues converge at the center of the ring. Due to the annular hole, the Bower ring greatly improves the utilization of the inner space of the ring and the inner surface of the ring, and the airflow resistance is small and the liquid distribution is uniform. Compared with the Raschig ring, the gas flux of the Pall ring can be increased by more than 50%, and the mass transfer efficiency is increased by about 30%. The Pall ring is a widely used filler.
