Classification: Metal Pall Rings, Plastic Pall Rings, Ceramic Pall Rings
● Plastic Pall Rings: Common specifications include φ25×25×1.2, φ38×38×1.4, φ50×50×1.5, φ76×76×2.6, etc. The specific surface area ranges from 72 to 213 m²/m³, the porosity is 91%-92%, and the bulk weight is 60-85 kg/m³.
● Metal Pall Rings: Specifications such as φ25×25×0.5, φ38×38×0.6, φ50×50×0.8, φ76×76×1.2, etc. The specific surface area is 71-219 m²/m³, the porosity is 96%, and the bulk weight is 308-396 kg/m³.
● Ceramic Pall Rings: φ25×25×3, φ38×38×4, φ50×50×5, φ76×76×9 are commonly used. The specific surface area is 70-210 m²/m³, the porosity is 73%-80%, and the bulk weight is 470-630 kg/m³.
● Chemical industry: Widely used in various rectification towers, absorption towers, desorption towers and other equipment for processes such as separation, purification, and absorption of mixtures, e.g., separation of petroleum cracking gas, gas absorption in acid-base neutralization processes, etc.
● Environmental protection: Applicable in wastewater and waste gas treatment devices. For example, in waste gas treatment, they are used for absorption of acidic gases and removal of odors; in wastewater treatment, they are used in aeration tanks and other equipment to improve oxygen transfer efficiency and promote the decomposition and removal of pollutants by microorganisms.
● Pharmaceutical industry: Used in processes such as separation, purification, and concentration of drugs, e.g., extraction of antibiotics, separation of active ingredients in traditional Chinese medicine, etc. Their excellent mass transfer performance and corrosion resistance help ensure the quality and efficiency of pharmaceutical production.
● Petroleum industry: Play an important role in the refining and separation of crude oil, effectively improving separation efficiency and reducing energy consumption. For instance, they are used as packing in equipment such as atmospheric and vacuum distillation units and catalytic cracking units.
● Large flux: The windowed structure increases gas-liquid flow channels, allowing gas and liquid to pass through the packing layer more smoothly. Compared with Raschig rings, the processing capacity can be increased by more than 50%.
● Low resistance: The gas-liquid flow resistance is significantly reduced. At the same processing capacity, the pressure drop can be reduced by about half, thereby lowering energy consumption and operating costs.
● High separation efficiency: Improved gas-liquid distribution and full utilization of the inner surface enable more sufficient contact and mass transfer between gas and liquid phases, with mass transfer efficiency increased by approximately 20%, thus enhancing separation effects.
● Large operating flexibility: Within a certain range, when gas-liquid flow rates change, they can still maintain good operational performance and separation efficiency, with strong adaptability to fluctuations in the production process.
