Beschreibung
Zusammenfassung:	A CO2 adsorption and recovery system including an intake unit, a first purification/adsorption/regeneration unit, a second purification/adsorption/regeneration unit, a three-way valve switching unit, a vacuum drawing unit and an exhaust unit is provided. The first and second purification/adsorption/regeneration units have a hollow fiber bundle impurity adsorption column, a hollow fiber bundle CO2 adsorption column and two heating devices. One set of adsorption columns performs purification and adsorption procedures to the inlet gas in a normal or high pressure condition, and the other set of adsorption columns performs desorption and regeneration procedures in a high temperature condition when the adsorption columns are heated by the heating devices. The three-way valve switching unit exchanges the purification and adsorption procedures with the regeneration procedure to the first and second units. The vacuum drawing unit draws CO2 desorbed from the CO2 adsorption columns alternatively. The exhaust unit drains a purified product gas out.
