Description

Technical Field

[0001] The utility model relates to the technical field of purification, in particular to a chemical purification reaction kettle. Background Art

[0002] Chemical purification generally adopts distillation process, which is a thermodynamic separation process. It uses the different boiling points of each component in the mixed liquid or liquid-solid system to evaporate the low-boiling point component and then condense it to separate the whole component. It is a unit operation process of evaporation and condensation. Compared with other separation methods, such as extraction, filtration and crystallization, it has the advantage of not needing to use other solvents other than the system components, thereby ensuring that no new impurities are introduced. The existing distillation process generally heats the liquid directly. This method heats up quickly and has a high distillation efficiency, but it is only suitable for separation and purification of liquids with two different boiling points. For liquids with close boiling points, there are certain problems in using it. For this reason, a chemical purification reactor is proposed. Utility Model Content
