<p>PROBLEM TO BE SOLVED: To provide an exhaust gas cooling and harmful substance removing method capable of simultaneously performing the cooling of exhaust gas and the removal of a harmful substance by one apparatus, capable of keeping the removal ratio of the harmful substance high, also preventing the re-synthesis of dioxin, not taking an apparatus arranging space and capable of suppressing equipment cost or running cost relatively low. SOLUTION: In a method for cooling exhaust gas and removing a harmful substance in the exhaust gas, a fluidized bed treatment apparatus 1 is used and, in such a state that the fluidizing chamber 2 of this apparatus 1 is packed, for example, with granular activated carbon with a size of 0.3-4.0 mm, the exhaust gas is sent into the fluidizing chamber 2 to fluidize activated carbon and a cooling liquid is sprayed and dripped on activated carbon to remove the heat of the exhaust gas to lower the temp. thereof and the harmful substance in the exhaust gas is bonded to activated carbon to remove the harmful substance from the exhaust gas.</p> |
