The utility model discloses a heat recovery device for flue gas of sulfur incinerator, which is connected to the outlet of the sulfur incinerator, including a cooling tower body. The cooling tower body is connected with an intake pipe and an outlet pipe, and also includes a heat recovery tower. The heat recovery tower is connected to the outlet pipe through a preliminary heat recovery pipe. A spray cooling device is arranged in the heat recovery tower, and a heat exchanger and a spray are arranged at the side of the heat recovery tower. The spray cooling device and the primary heat recovery tube are connected to the heat exchanger respectively; the SO2 gas formed by combustion of the sulfur incinerator enters the cooling tower for temporary storage, and then is transported to the heat recovery tower through the primary heat recovery tube. The temperature of SO2 gas is lowered through the cooperation of the primary heat recovery tube, spray cooling device and heat exchanger, and the heat is transferred to the heat exchanger to make the heat exchanger. The inner water is heated to form hot water and is conveyed outward. The SO2 gas after cooling is conveyed outward from the heat recovery tower to the next process tank. Through this device, the heat energy of SO2 gas can be recovered and utilized, and the waste of heat energy can be avoided.
