пластиковые кольца Полла

Plastic pall rings' height is the same to its diameter, with pores, pores area is 30% of itstotal area. Such structure improves gas-liquid distribution, making full use of theplastic pall rings'surface, due to this, the in-tower gas and liquid can pass through theplastic pall rings'pore successfully Technical dataof plastic pallrings: Spec.D*H*T (mm)Number per m³Bulk density (kg/m³)Surface area (m²/m³)Free volume (%)F factor (m-1)Dg1616*16*1.111200014118891249Dg2525*25*1.25350015017590239Dg3838*38*1.4158009811589220Dg5050*50*1.5650074.811290154Dg7676*76*2.6193070.9739294 Advantages of plastic pall rings: Plastic pall rings are made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF) Plastic pall rings are featured with high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60to 150 Application of plastic pall rings: Plastic pall rings are widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection
