Beschreibung
Zusammenfassung:	The invention belongs to the technical field of flue gas purification and discloses a flue gas purification resource recovery system and method. The resource recovery system comprises a flue gas low-temperature adsorption, purification and regeneration system, an alkali preparation system, a first purification system, a sodium pyrosulfite synthesis system, a tail gas treatment system and a separation and drying system. The flue gas low-temperature adsorption, purification and regeneration system comprises a cooling device for cooling flue gas to low-temperature flue gas below the room temperature, a low-temperature adsorption device for adsorbing and purifying the low-temperature flue gas into clean flue gas through an adsorbent, and a regeneration device for regenerating the adsorbent saturated in adsorption and generating sulfur-containing regenerated gas; the first purification system is connected with the regeneration device; and the sodium pyrosulfite synthesis system is connected with the alkali prepara
