PROBLEM TO BE SOLVED: To provide an exhaust gas treating equipment for a reduced iron manufacturing equipment and its operating method, capable of preventing the blockage of an exhaust gas suction duct and the damage of lined refractory. SOLUTION: This exhaust gas treating equipment for the reduced iron manufacturing equipment is constituted so that it reduces lumped products obtained by mixing the iron oxide produced in an iron manufacturing process and a coal material, and a cooling refrigerant supplying equipment for supplying a cooling medium to the exhaust gas is set at a previous stage of the exhaust gas suction duct sucking the exhaust gas.
