Amine liquid recovery system and amine liquid recovery method

The invention relates to an amine liquid recovery system and an amine liquid recovery method, and belongs to the technical field of carbon dioxide trapping solvent recovery. The amine liquid recoverysystem comprises an amine liquid tank, a heater, a cooler and a gas-liquid separator, wherein the amine liquid tank is used for storing a to-be-treated mixed solution; an inlet of the heater is connected with the amine liquid tank through a first valve; a heating device for heating the mixed solution to be boiled is arranged in the heater; an inlet of the cooler is connected with an outlet of theheater; a gas-liquid inlet of the gas-liquid separator is connected with an outlet of the cooler; a gas outlet of the gas-liquid separator is connected with a second valve and a vacuum pump. Accordingto the amine liquid recovery system and amine liquid recovery method of the invention, the mixed solution is heated to boil through the heater, so that water is evaporated, carbon dioxide is desorbed, and the water and carbon
