CPC C25B 3/26 (2021.01) [C25B 15/087 (2021.01)] | 7 Claims |
1. A system for CO2 capture and electroregeneration and synchronous conversion, comprising: a CO2 capture subsystem and a CO2 electroregeneration and synchronous conversion subsystem;
wherein the CO2 capture subsystem uses an absorption liquid to capture CO2 and generate a capture liquid;
the CO2 electroregeneration and synchronous conversion subsystem comprises an electrolytic cell; a cation exchange membrane and an anion exchange membrane are arranged in the electrolytic cell at an interval, the cation exchange membrane and the anion exchange membrane separate the electrolytic cell into an anode chamber and a cathode chamber at the left and right ends, and a balance chamber in the middle;
an anode electrode is arranged in the anode chamber, the anode chamber is further provided with a sample inlet and a sample outlet; a cathode electrode is arranged in the cathode chamber, and the cathode chamber is further provided with a sample inlet and a sample outlet; the balance chamber is provided with a sample outlet; and
the sample inlet of the anode chamber is connected to an outlet of the capture liquid of the CO2 capture subsystem, and the sample outlet of the anode chamber is connected to the sample inlet of the cathode chamber for introducing CO2 regenerated by anodic oxidation into the cathode chamber for electroreduction; and the sample outlet of the balance chamber is connected to an inlet of the absorption liquid of the CO2 capture subsystem.
