Recycling device for converter diffused flue gas in iron and steel plant

The utility model discloses a recycling device for converter diffused flue gas in a steel plant and relates to the technical field of combustion. In order to solve the problems that diffused flue gas generated by converter steelmaking cannot be recycled, so that a large amount of energy is wasted, the flue gas is diffused into natural air, and the environment is polluted. Diffused flue gas generated in the converter steelmaking process is recycled and reused, the diffused flue gas is completely combusted in a converter diffused flue gas incineration unit to release all heat, the heat is recycled and converted into steam through a vertical waste heat boiler to be comprehensively utilized by enterprises, the temperature of high-temperature flue gas obtained after heat exchange is reduced to 140 DEG C or below, and the heat is recycled and reused. Then feeding into a chimney through an induced draft fan and discharging into the atmosphere; therefore, environmental pollution and energy waste are avoided, and carb
