<p>PROBLEM TO BE SOLVED: To treat dust being a solid in exhaust gas or carbon monoxide or carbon dioxide being a gaseous component therein. SOLUTION: Aluminum A is introduced into a reaction container 1 and heated by an electric heater 8 to be melted. Next, exhaust gas is blown into the container 1 in a fine bubble form from a plurality of blowoff ports 3. Since the substance reduced in molten aluminum A and aluminum oxidized therein are gathered to the upper surface and bottom of molten aluminum A by the specific gravity difference from molten aluminum A, they are appropriately taken out of lower and upper taking-out ports 4, 5 to be recycled. The reduced substance and aluminum vapor contained in the exhaust gas passed through molten aluminum A are cooled by a cooler 11 to be removed. The exhaust gas from which dust is removed is discharged to the atmosphere from an upper gas exhaust pipe 10.</p> |
