Technical description of alcohol recovery tower and alcohol distillation tower

It is the main direction of the development of alcohol distillation technology to effectively improve the fractionation efficiency of alcohol recovery tower and alcohol distillation tower, reduce alcohol loss and save energy To improve the heating efficiency, the packing structure and the tray efficiency are the main means to improve the fractionation efficiency, reduce the alcohol loss and save energy Stainless steel corrugated packing is used The packing has the advantages of large specific surface area, small pressure drop, good gas distribution in alcohol recovery tower and good fractionation effect The application of this technology greatly improves the fractionation efficiency of the packed tower, thus improving the whole tower efficiency It can save energy by 20% - 30%, the alcohol concentration of residual liquid can be ≤ 5%, and the packing is easy to clean, not easy to scale, not slag, not easy to block the section channel of the tower body, and the operation is stable and reliable Using the jacket external circulation evaporator as the tower kettle heating evaporation device, its evaporation efficiency is greatly improved compared with the traditional "U" tube heating kettle Under the same heating area, its evaporation speed can be increased by 1-2 times, and the tower kettle can be automatically cleaned without disassembly, which greatly improves the operation convenience The distillation column system also realizes the integrated installation of condenser and tower and the process operation mode of low reflux ratio regulation, which greatly improves the operation convenience and process stability of distillation.
