<p>PURPOSE:To provide a method of exhaust gas disposal in which soot and dusts are classified into those that are easy to be disposed of and those that are difficult to be disposed of and the volume of generation of fly ash can be reduced and a device of exhaust gas disposal. CONSTITUTION:The exhaust gas that is discharged from an incinerator 1 is cooled and after mainly the soot and dusts are removed by a first bag filter 3 from the cooled exhaust gas, calcium hydroxide is sprayed to the exhaust gas after the removal of the soot and dusts, and the exhaust gas to which the calcium hydroxide is sprayed is cleaned by a second bag filter 5. Since the soot and dusts are removed by the first bag filter 3, they can be mixed with the incineration ash and the mixture can be easily disposed of by melting. And since the fly ash that contains an acid gas, etc., is removed by the second bag filter 5, the volume of the fly ash is much reduced.</p> |
