Description

Technical Field

[0001] This utility model belongs to the technical field of batch distillation columns, specifically relating to a batch distillation column with an intermediate storage tank. Background Technology

[0002] Batch distillation, also known as fractional distillation, involves adding all the material into the distillation column at the start of the operation and gradually heating and vaporizing it. The vapor drawn from the top of the column is condensed, with part of it being used as the distillate product and the other part being returned to the column as reflux. Once the composition of the liquid in the bottom container drops to a specified value, it is discharged all at once, and then the next batch of distillation is carried out. Intermittent distillation, on the other hand, requires the use of a batch distillation column.

[0003] Currently, existing batch distillation columns with intermediate storage tanks produce viscous liquid and solid residue after the reaction. The viscous liquid adheres to the bottom of the column, and cleaning with a cleaning solution is insufficient to remove the solid residue adhering to the inner wall of the column, affecting the subsequent use of the batch distillation column. Therefore, we propose a batch distillation column with an intermediate storage tank. Utility Model Content

[0004] The purpose of this invention is to provide an intermittent tower with an intermediate storage tank to solve the existing problems mentioned in the background art.
