Disclosed is a duct-type dry reactor of Bio-SRF combustion exhaust gas to reuse unreacted slaked lime and to enhance an efficiency of acidic gas reaction. The duct-type dry reactor using a neutralizing agent to remove harmful acidic gases generated upon combustion of solid fuels in the present incinerator and SRF or Bio-SRF and positioned in the front end of back filter comprises; a porous cylindrical member allowing penetration of harmful acidic gases, fly ashes, a neutralizing agent flowing in from the front end of a duct-type dry reactor; a rotary member connected with the porous cylindrical member to supply a torque to the porous cylindrical member ; a screening panel to show a moving path for harmful acidic gases and fly ashes so that harmful acidic gases and fly ashes can be moved to the back filter after penetrating the porous cylindrical member; and a transfer conveyor separated from the porous cylindrical member by a preset distance and positioned on the top of the porous cylindrical member to be supplied of an unreacted neutralizing agent and fly ashes from the back filter and to allow moving of the unreacted neutralizing agent and fly ashes. By reuse of the unreacted neutralizing agent emitted from the back filter, and reflowing of the unreacted neutralizing agent and fly ashes into the duct-type dry reactor, the invention can reduce emissions of fly ashes generated from combustion of an incinerator and solid fuels, and enhance a reaction efficiency of acidic gases. |
