1)  light-porous packing materials
轻质多孔填料
1.
The results showed that the capability of compound packing materials(light-porous packing materials(above)-packing materials of enhanced biofilm(middle)-porous concavo-convex packing materials(below)) was better than that of above three single packing materials,and its pressure drop was lower,probability of liquid flooding was reduced.
结果表明:轻质多孔填料(上)-强化挂膜填料(中)-多孔凹凸填料(下)组合填料的性能优于单一轻质多孔填料、强化挂膜填料及多孔凹凸填料,阻力较小,液泛几率减少;运行60天,组合填料滴滤塔的阻力为680~700 Pa,硫化氢、氨、甲硫醇及挥发性有机化合物去除率均大于98%。

多孔碳填料
补充资料:填料函填料
分子式:
CAS号:

性质:又称填料函填料或螺旋盘根。主要用于填塞反应釜、搅拌器、泵等旋转轴或往复活塞杆及阀杆轴贯通处的填料函(stuffing box),以抑止旋转或往复运动的轴杆处的低压蒸汽、气体、热水、溶液及各种介质的泄漏。常以棉麻、石棉、聚四氟乙烯、碳纤维、金属箔等单独或几种材料组合,经捻合、编织或与橡胶并用制成,为条状产品。横断面有正方形、梯形、圆形等,填料条按其截面大小绕成不同直径的螺旋状制品,使用时将其切断成适当周长的环,卷于轴的四周,依次塞入填料函中,用盖锁紧,完成密封。
