Description

Technical Field

[0001] The utility model relates to the technical field of distillation, in particular to a multi-component separation distillation device for industrial organic reactions. Background Art

[0002] The commonly used method for separation and purification of multi-component liquid organic compounds is distillation technology. By utilizing the boiling point difference of various chemical components, the material is heated to a certain temperature in a distiller, wherein the component with a lower boiling point is converted from liquid to gas after being heated, and the gaseous component enters the condensation recovery device, and is converted back to liquid after cooling below the boiling point, while the component with a higher boiling point remains in the distiller in a liquid state, thereby achieving the separation of high and low boiling point components. The distillation method is a simple and effective method for separating liquid organic compounds with simple components. However, the separation and purification of multi-component liquid organic compounds, especially the separation and purification of temperature-sensitive natural substances and the distillation of high-boiling point materials, is relatively troublesome. Under the condition of continuous feeding, in principle, one distillation operation corresponds to a set of distillation operation parameters, and only one component can be separated. The separation of multiple components generally requires repeated operations using different distillation operation parameters. The process is discontinuous, the operation is relatively cumbersome, and the operation time is long. For this reason, we propose a multi-component separation distillation device for industrial organic reactions to solve the above problems. Utility Model Content
