设备说明
精馏塔是进行精馏的一种塔式汽夜接触装置，根据操作方式可分为连续精馏塔和间歇精馏塔，蒸馏釜加热方式有外循环式和内循
环式两种供选。
设备特点
本装置采用高效不锈钢波纹填料，凡接触酒精部位，如塔体、冷凝器、稳压罐、冷却蛇管等均采用不锈钢，以确保成品酒精不被污染，塔釜采用可拆式 U 型管，这样便于对加热外壁及蒸馏釜内壁进行清洗。
用途
本装置适用于制药、食品、轻工、化工等行业的酒精回收，以利于降低生产成本，提高经济效益，本装置可将30%-50％的稀酒精蒸馏到90%-95%，成品酒精度要求高，可加大回流比，但相应成品产量降低，排放残液含醇度：≤0.1%，是回收酒精的
专业设备。
Device Description
The rectification tower is a tower type vapor - liquid contact device for rectification . According to the operation mode , it can be divided into a continuous rectification tower and a batch rectification tower ; the heating method of the distilation ketle has two options : external circulation and
internal circulation .
Features
This device adopts high - eficiency stainless steel corrugated packing . Al parts that contact alcohol , such as tower body , condenser , voltage stabilizing tank , cooling coil , etc ., are made of stainless steel to ensure that the finished alcohol is not contaminated . The tower ketle adopts a detachable U - shaped tube . It is convenient to clean the heating outer wal and the inner wal of the stil .
Use
This device is suitable for alcohol recovery in the pharmaceutical , food , light industry , chemical and other industries to help reduce production costs and improve economic benefits . This device can distil 30%-50% of dilute alcohol to 90%959%, finished alcohol High degree of requirements , the reflux ratio can be increased , but the output of the corresponding finished product is reduced , and the alcohol content of the discharged residual liquid :≤0.1%. It is a professional equipment for alcohol recovery .
本设备可采用外加热 JHW 或内加热 JHN 两种形式，外加热蒸发速度快，较多适用于 JH ·800以上结构，可边回收酒精边浓缩料液。
This equipment can adopt two forms of external heating J Н W or internal heating JHN . The evaporation speed of external heating is fast , and it is more suitable for structures above JH800. It can concentrate the liquid while recovering alcohol .
