Pall ring packing is a new type of packing, which is improved for some main shortcomings of the rasping ring. It opens eight layers of small rectangular Windows on the wall of the common rasping ring, and the small window blades overlap in the center of the ring, and the upper and lower surface layer Windows intersect each other.

The main difference between Bauer ring and rasping ring is that there is a rectangular window hole on the side wall, and the window blade of the window hole is bent into the center of the ring. The distribution performance of gas and liquid is greatly improved compared with that of rasping ring due to the opening of the ring wall, especially the inner surface area of the ring can be fully utilized.

The characteristics of Pall ring include: the ring wall is open, which greatly improves the utilization rate of the inner space and the inner surface of the ring, the airflow resistance is small, and the liquid distribution is uniform; It has the advantages of large flux, low resistance, high separation efficiency and high operating elasticity. Under the same pressure reduction, the processing capacity can be more than 50% larger than the rasping ring; Compared with the rasping ring, this filler has the characteristics of large production capacity, strong resistance, and large operating elasticity, under normal circumstances, the same pressure drop treatment is 50%-100% larger than the rasping ring, the same treatment pressure drop is 50%-70% smaller than the rasping ring, the gas flux of the Pall ring can be increased by more than 50%, and the efficiency of the mass transfer equipment is increased by about 30%.
