description The utility model discloses a comprehensive and efficient recycling device for blast furnace smelting gas, which comprises a flue gas combustion heater, a combustion nozzle and a heat absorption coil pipe are arranged in the flue gas combustion heater, blast furnace smelting flue gas is introduced into the combustion nozzle, and the heat absorption coil pipe is connected in series on a water replenishing pipe of a steam boiler. The flue gas combustion heater is further provided with an exhaust port and a combustion-supporting air pipe, the combustion-supporting air pipe is provided with an air blower, and an air rough filtration mechanism is arranged on the upstream of the air blower. The oxygen content in combustion-supporting air entering the flue gas combustion heater is increased by 4-6% through the air rough filtration mechanism, so that combustion of carbon monoxide is more sufficient; carbon monoxide is fully combusted to provide more heat for heating water flow of the heat absorption coil pipe, so tha
