Technical Field

[0001] The utility model relates to the technical field of organic amine regeneration, and particularly relates to an organic amine regeneration device. Background Art

[0002] Organic amine is an important organic compound, a colorless transparent liquid with a strong ammonia odor, toxic, and slightly soluble in water. The aqueous solution is weakly alkaline. In the organic synthesis industry, it is often used as a solvent, catalyst, polymerization inhibitor, preservative, and raw material for synthesizing other substances.

[0003] In the traditional organic amine recovery equipment, the temperature and pressure are not easy to control. During the amine recovery process, the purity of the recovered organic amine is often insufficient due to excessive temperature and pressure, or the regeneration efficiency of the organic amine is low due to too low temperature and pressure, resulting in waste of resources.
