Abstract: An integrated device and a method for continuously capturing, storing and separating a flue gas in an underground rock stratum are provided. An injection well, a monitoring well and an emission well are arranged in sequence at locations from near to far from a flue gas emission source. The injection well, the monitoring well and the emission well are respectively drilled to different depths in a storage rock stratum. A horizontal injection channel is arranged at bottom end of the injection well. During migrating the flue gas in the storage rock stratum, CO2 and sulfur nitride are absorbed by a rock porous medium and gradually enriched, and meanwhile, the CO2 and sulfur nitride, after chemically reacting with water, minerals and biomass in a rock, are gradually mineralized to achieve storage; and separated N2 is gradually migrated upwards to the emission well to achieve separation.
