Dry sorbent CO2 capturing system including function of supplying water using energy in system and operation method thereof

The present invention is directed to a process by using the energy generated in the self-hydration is possible dry carbon dioxide absorption system, a water supply method and an operation method of the collection system. More specifically, the apparatus for supplying moisture into the recovery reactor of dry carbon dioxide capture system, the flue gas for cooling the exhaust gas to be introduced into the recovery reactor cooling section; First heat exchange flow passage flows into the exhaust gas cooling portion over a separate line in which water is heated by absorbing heat of the exhaust gas; An energy storage unit that is the water produced in the first heat exchange passage is stored; And the water stored in the energy storage unit water supply unit for supplying toward the recovery reactor; relates to a water supply system using the energy generated in the collection system comprising: a.
