<p>PURPOSE:To provide a method and device for treating waste gas, by which dust and harmful gas components in waste combustion gas are effectively removed and treated using slaked lime. CONSTITUTION:In a method for treating waste gas whose harmful gas components are absorbed by the reaction with slaked lime, the recovered reacted slaked lime is given crushing treatment and the crushed slaked lime is supplied again to the waste combustion gas by circulation. In a device for treating waste gas, a slaked lime feeder 4 for supplying slaked lime is installed in a communicative pass 3 of a combustion furnace 1 and a dust collector 2, a slaked lime collector 6 for recovering the reacted slaked lime is connected to the dust collector 2 and a crusher 7 for crushing the recovered slaked lime is connected to the slaked lime collector 6 and the crusher 7 and the communicative pass 3 are connected by a circulating pass 3.</p> |
