金属散堆填料金属散堆填料材质主要包括碳钢、铝合金及不锈钢。由于其壁薄、空隙率大，通量大，阻力小，分离效果好，特别适用于真空精馏塔。处理热敏性、易分解、易聚合、易结碳的物料。金属散堆填料有共轭环、八四内弧环、矩鞍环、扁环、阶梯环和鲍尔环等。名称规格直径×高度×壁厚mm比表面积m2/m3空隙率∑m3/m3堆积重量YPKg/m3堆积个数n/m3干填料因子a/∑3m-1共轭环Φ2525×25×0.31859531275000216Φ3838×38×0.51169627519500131Φ5050×50×0.88696275977097Φ7676×76×1.08197245398095八四内弧环Φ2525×25×0.62509342059200310Φ3838×38×0.61389529614000163Φ5050×50×0.8121953507000144Φ7676×76×1.07595280195086矩鞍环Φ2525×20×0.618596409101160209Φ3838×30×0.81129636524680137Φ5050×40×1.075962911040085Φ7676×60×1.25897245332063扁环Φ1616×5.5×0.534892604630000312Φ2525×9.0×0.622894506160000280Φ3838×12.7×0.71509539048000175Φ5050×17×0.81159727521500156阶梯环Φ2525×12.5×0.52219538398120257Φ3838×19×0.61539632530040173Φ5050×25×0.81099630812340123Φ7676×38×1.27296306354081鲍尔环Φ2525×25×0.52199539315180255Φ3838×38×0.6146963186500165Φ5050×50×0.8109963146500124Φ7676×76×1.27196308183080)
