精馏是借助回流技术来实现高纯度和高回收率的分离操作 在抗生素药物生产 中 需要甲醇溶媒洗涤晶体 洗涤过滤后产生废甲醇溶媒 然后对甲醇溶媒进行精 馏 操作一般在塔设备中进行 塔设备分为两种 板式塔和填料塔 填料塔结构简 单 装置灵活 压降小 持液量少 生产能力大 分离效率高 耐腐蚀 且易于处 理易气泡 易热敏 易结垢物系等优点 同时也有投资费用较高 填料易堵塞等缺 点 近年来由于填料塔结构的改进 新型的高负荷填料的开发 既提高了塔的通过 能力和分离效能又保持了压降小及性能稳定的特点 因此 填料塔已被推广到大型 气液操作中 在某些场合还代替了传统的板式塔 从设备设计的角度看 不论板式 塔还是填料塔 基本上由塔体 内件 裙座 和附件构成 近年来由于填料塔结构 的改进 新型的 高负荷填料的开发 既提高了塔的通过能力和分离效能又保持了 压降小以性能稳定等特点 因此填料塔已被推广到大型汽液操作中 在某些场合还 代替了传统的板式塔 但国内在这方面的研究则较少 如何设计规整填料蒸馏塔已 成为一个重要的课题 它对自行设计 改进现有设备生产状况都较为重要 随着对 填料塔的研究和开发 性能优良的填料塔必将大量用于工业生产中 关键词 精馏 填料塔 设备设计 dustryandthecompanyofaboutrequirements combinedopenminesafetyofactual

reflux technology to achieve the separation of high purity and high recovery operation in the production of antibiotics methanol solvent washing crystal washing the filtered waste methanol solvent and then the methanol solvent distillation The operation generally tower equipment tower equipment is divided into two types plate tower and packed tower Packed tower structure is simple flexible devices low pressure drop hold less liquid large production capacity and high separation efficiency corrosion resistance and easy to handle and easy bubble easy to thermal easy to scale in the Department of advantages but also investment costs higher filler easy to plug the shortcomings In recent years due to the improvement of the packed tower structure the development of new high load packing both to improve the tower through the capacity and separation efficiency while maintaining low pressure drop and stable performance characteristics Therefore the packed tower has been extended to large scale gas liquid operations in some cases instead of the traditional plate tower In recent years due to the improvement of the packed tower structure the development of new high load packing not only improves the tower capacity and separation efficiency while maintaining the pressure drop and small to stable performance Packed tower has been extended to the large vapor liquid operations in some cases instead of the traditional plate tower Domestic research in this area is less how to design a structured packing distillation tower has become an important issue its own design improvement of existing equipment conditions are more important With the research and development of the packed tower the excellent performance of the packed tower is bound to a large number of industrial production

减湿和气液相反应过程 所以塔设备的研究一直是国内外学者普遍 关注的重要课题 填料塔的应用始于 19 世纪中叶 起初在空塔中填充碎石 砖块和焦炭等块状物 以增强气液两相间的传质 1914 年德国人 F 拉西首先采用高度与直径相等的陶瓷环 填料 现称拉西环 推动了填料塔的发展 此后 多种新填料相继出现 填料塔的 性能不断得到改善 近 30 年来 填料塔的研究及其应用取得巨大进展 不仅开发了数 十种新型高效填料 还较好地解决了设备放大问题 到 60 年代中期 直径数米乃至 十几米的填料塔已不足为奇 现在 填充塔已与板式塔并驾齐驱 成为广泛应用的 传质设备 填料塔自它发明以来已广泛地应用于化工生产的各个领域 近二十年 规整填料塔对板式塔 散装填料以及其它多种塔设备产生了巨大的冲击 在国内外引起众多研究者的极大兴趣 在近几年的文献中 国外有大量的规整填料 研究报道 它因其高通量 低压降 操作稳定而广泛地用于气 液 液 液接触的塔设 备中 如蒸馏 吸收 萃取等诸多领域 特别是在气液接触中 已越来越多地被采 用 如已有设备通过利用规整填料来更换塔内构件 从而达到提高塔负荷的目的 规整填料种类较多 有板波纹填料 格栅填料 丝网填料等 材质有金属 塑料 陶瓷等 即使同样的种类亦有不同的规格 它们的比表面 空隙率及几何尺寸存在
