Generally, the opening area accounts for about 30% of the total area of the ring wall, so that the gas and liquid in the packed tower can pass freely through the window hole, improving the gas-liquid distribution and making full use of the inside of the ring. The surface increases the mass transfer efficiency.Compared with the Raschig ring, the treatment capacity can be more than 50% larger, and the pressure is reduced by half; generally made of metal, plastic or ceramic.Pall ring packing has the advantages of large flux, low resistance, high separation efficiency and large operational flexibility. Under the same pressure reduction, the treatment volume can be more than 50% larger than Raschig ring. At the same throughput, the pressure drop can be reduced by half and the mass transfer efficiency can be increased by about 20%. Compared with the Raschig ring, this kind of packing has the characteristics of large production capacity, low resistance and large operation flexibility. Under normal circumstances, the treatment can be 50%-100% larger than the Raschig ring, and the pressure drop ratio is similar. Raschig Ring is 50%-70% smaller, and the tower height is also depressurized. The Pall ring can be used for about 20%-40% of the packing volume.Ministry of Chemical Industry Standard: 21556.2-95Plastic Pall ring packing is especially suitable for low-temperature (60-280 degree) stripping, absorption and washing towers in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries, as well as carbon dioxide degassing tower, ozone contact reflection tower and other reaction towers, as contact packing.How to choose Plastic pall ring:To select plastic Pall ring can be judged in several ways. First look at how the efficiency of its transmission quality, under the premise of satisfying the process, the mass transfer efficiency will be higher. Secondly, the flux. Under the same liquid, the higher the gas velocity of the packing, the greater the flux, then the higher the efficiency and mass transfer efficiency. In addition, the quality can be judged by the pressure drop of the packing layer. The lower the pressure drop, the lower the power it consumes, so the lower the operating cost. Of course, its operational performance is also an important criterion for judging quality. Products with elasticity and strong anti-blocking properties represent better quality.Technical DataProduct NamePlastic Pall RingMaterialPP/RPP/PVC/CPVC/PVDF/PTFE,etcLife Span>3 yearsSize mmSurface Aream2/m3Void Volume%Packing Numberpieces/ m3Packing DensityKg/m3Dry Packing Factor m-13/5"16*16*118891170000852751"25*25*1.21759053500692391-1/2"38*38*1.41158915800692202"50*50*1.593906500521273"76*76*2.673.292192748944"100*100*352.89410004882FeatureHigh void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer.Advantage1.
