Flue gas treatment and waste heat generation system with rotary hearth furnace

The utility model relates to a flue gas treatment and waste heat generation system with a rotary hearth furnace, belonging to mechanical equipment. The flue gas treatment and waste heat generation system comprises the rotary hearth furnace, a high-temperature flue gas treatment and waste heat utilization device, a low-temperature flue gas treatment and waste heat utilization device, a cyclone wind mixer, a bag dust collector, a draught fan, a chimney and a turbine generator, wherein high-temperature flue gas generated by the rotary hearth furnace passes through the high-temperature flue gas treatment and waste heat utilization device, the low-temperature flue gas treatment and waste heat utilization device, the cyclone wind mixer, the bag dust collector and the draught fan and then enters the chimney; and a steam output port of the high-temperature flue gas treatment and waste heat utilization device is connected to a turbine which is connected with generator. According to the flue gas treatment and waste heat generation system, normal production of the rotary hearth furnace can be ensured, the discharge of dust in flue gas can be reduced and high-concentration zinc ash in the flue gas is recovered; and meanwhile, high-temperature waste heat of the flue gas is utilized for generating power and favorable economic and social benefits are obtained.
