It is a kind of annular open-hole packing designed by our company and Nanhua Design Institute and jointly researched and developed by Tianjin University, which has strong anti-fouling performance, and its cleaning ability and aerosol entrainment amount are better than those of the saddle ring; Various specifications of ceramic stepped ring, with high density, high strength, good corrosion resistance characteristics, its height is about half of the diameter, one side of the ring has a conical flanging, the ring wall is evenly distributed four high holes, the ring is provided with rice word inner rib. The unique structural design makes the filler mainly in point contact when stacking, which not only increases
The porosity of the packing reduces the resistance of the airflow and greatly improves the gas-liquid distribution performance in the packing layer, and the packing has been widely used in the dry suction tower of sulfuric acid production and other chemical projects.
