Pall ring packing is a new type of packing. Its structure is to open a rectangular window hole on the ring wall. The curved design of the window blade increases the contact area between the packing and the gas and liquid, thereby improving the mass transfer efficiency. Pall ring packing is divided into a variety of materials such as ceramics, metals, and plastics. Among them, metal materials include 304, 316, 316L, carbon steel, 201, 410, etc., and plastic materials include PP, RPP, CPVC, PVDF, PVC, PTFE, FEP, PFA, etc. The appropriate material can be selected according to different operating environments and media.
1. Petroleum and chemical industry:
- Especially suitable for medium and low temperature (60-120 degrees) distillation, absorption and washing towers. Ball ring packing has the advantages of large flux, low resistance, high separation efficiency and large operating flexibility. Under the same pressure reduction, the processing capacity can be more than 50% larger than that of Raschig ring.
- Plastic pall ring packing is also suitable for medium and low temperature (60-150 degrees) steam lifting, absorption, washing towers, etc.
2. Environmental protection industry:
- Metal pall ring packing is suitable for various environmental separation, absorption and absorption devices, such as processing heat-sensitive, easily decomposed, easily polymerized and easily carbonized materials.
3. Chemical packing tower:
- Ceramic pall ring packing is suitable for various high and low temperature occasions due to its acid resistance, alkali resistance, heat resistance and good oxidation resistance. It is often used as contact packing and other reaction towers in carbon dioxide degassing towers, ozone contact reaction towers, etc.
- Metal pall ring packing is also widely used in packing towers in petrochemical, chemical, environmental protection and other industries.
4. Metallurgy, coking, sulfuric acid, water treatment and other industries:
- Ceramic pall ring packing is widely used in various packing towers such as drying towers, cooling towers, washing towers, distillation towers, synthesis towers, catalytic towers and spray towers.
Pall ring packing has been widely used in many industries such as petroleum, chemical, environmental protection and metallurgy due to its excellent physical and chemical properties. Among them, Pall ring packings made of different materials (such as polypropylene, ceramic, stainless steel, etc.) are suitable for different operating temperatures and chemical environments due to their different properties.
