Abstract:
This carbon dioxide utilizing system utilizes carbon dioxide in exhaust gas, reduces the amount of fresh concrete sludge that is generally discarded as waste and allows efficient recycling of calcium carbonate. The carbon dioxide utilizing system comprises an flue through which exhaust gas containing carbon dioxide passes, a spray nozzle that supplies fresh concrete sludge water to the flue, and a dust collector that recovers a reactant containing calcium carbonate generated by a reaction between the carbon dioxide in the exhaust gas and the fresh concrete sludge water.
