The invention discloses a thermal-electric co-driven CO2 capturing system adopting an amine method. The system comprises an absorption tower provided with an electrochemical system inside and a desorption tower provided with an electrochemical system inside, wherein both the absorption tower and the desorption tower are connected with heat exchangers. The system is characterized in that the inside electrochemical systems are formed by adding electrodes to the absorption tower and the desorption tower, so that the absorption and desorption processes are promoted, and energy consumption is reduced. The electrochemical systems can efficiently utilize reaction heat which cannot be utilized by the conventional amine method, the desorption temperature can be substantially reduced, and small-temperature-difference cyclic capturing of CO2 is realized. According to the proposed thermal-electric co-driven CO2 capturing process with the amine method, CO2 can be efficiently captured with low energy consumption, and the system has great engineering application value for efficient and low-cost emission reduction of CO2 in power plants and other industries.
