Abstract
A device and a method for continuous CO2 capture by a double-bed hydrate process are provided. The device includes a first fixed-bed hydrate reactor, a second fixed-bed hydrate reactor, a solution circulation system, a gas inlet system and an exhaust system; the first fixed-bed hydrate reactor and the second fixed-bed hydrate reactor are respectively connected in series with the gas inlet system, the exhaust system and the solution circulation system, and are connected in parallel; the refrigerant fluid and the heat medium fluid output by a compression-refrigeration system alternately flow into a heat exchange coil of the first fixed-bed hydrate reactor and a heat exchange coil of the second fixed-bed hydrate reactor, and the two fixed-bed hydrate reactors are alternately subjected to hydrate formation and decomposition reactions to realize continuous CO2 capture and separation.
