CO2 purifying structure of solid amine embedded metallic aluminum foam

The invention discloses a CO2 purifying structure of solid amine embedded metallic aluminum foam. The CO2 purifying structure comprises a plurality of purifying bed layers which are overlapped together in parallel, wherein a heat conducting dividing wall is arranged between the adjacent purifying bed layers, each purifying bed layer is a continuous slab framework composed of through hole aluminum foam, solid amine particles are packaged in the through hole aluminum foam, an inlet switch which can be switched on due to adsorption and switched off along due to desorption is arranged at one end of each purifying bed layer, a vacuumizing system which is in a closing state during adsorption and is in an opening state during desorption is connected to the other end of the purifying bed layer, and when one purifying bed layer is in an adsorption state, the adjacent purifying bed layers are in a desorption state. According to the CO2 purifying structure, through continuous and repeated conversion of an adsorption bed and a desorption bed, the integration of self-adaptive adsorption and desorption of CO2 is realized. By adopting the CO2 purifying structure, the complexity of a system is lowered by adopting a thermal vacuum condition; the adsorption heat is applied to desorption reaction, and thus the energy consumption of the system is reduced.
