Calcium carbonate processing method

The invention discloses a calcium carbonate processing method which comprises a carbonization tower for processing calcium carbonate, the carbonization tower is provided with an air inlet pipe, an exhaust pipe, a lime milk feeding pipe, a discharging pipe and a driving device, and the carbonization tower is internally provided with a discharging dispersing device, a scraping device and a dredging device. The method for processing calcium carbonate in the carbonization tower comprises the following steps: S1, feeding and carrying out carbonization reaction; firstly, carbon dioxide gas generated by firing slaked lime is introduced into the gas inlet pipe, then lime milk is introduced into the lime milk feeding pipe, and the lime milk is dispersed by the discharging dispersing device and enters the carbonization tower to be subjected to a carbonization reaction with the carbon dioxide gas; through the steps, materials attached to the discharging dispersing device and materials on the inner side wall of the carbo
