摘要
酒精回收塔是将浓度低的乙醇溶液通过蒸馏和分离,从而提高乙醇溶液的浓度。为了节省原料提高利用率,塔类设备在化工、制药领域得到广泛应用。下面以一个连续式酒精回收塔为实例,针对酒精回收塔系统各个单元的设计计算,阐述酒精回收塔的设计思路。
In alcohol recovery column, low concentration ethanol solvent is distillated and separated so as to be concentrated. In order to save raw material and raise usage rate, column like equipment is widely used in chemical and pharmaceutical industries. In this article, exampled with continuous alcohol recovery column, from view point of design and calculation for each element in this column, the thought of design of alcohol recovery column was expounded.
