step two: the gas passing through the side-blown smelting furnace from the first cooling tank (8) enters the second cooling tank (9) and contacts with a radiating fin (13) in the second cooling tank (9), the radiating fin (13) cools the gas, heat is guided out from an upper heat conducting plate (16) and a lower heat conducting plate (15) to the outer side of the first cooling tank (8), the surface of the first cooling tank (8) is cooled by using cold water in a cooling water pipe (14), the heated cold water is discharged from one end of the cooling water pipe (14) to a water outlet pipe (7), enters the cooler (5) from the water outlet pipe (7) for cooling, the cooled water is discharged from the cooler (5) and then sent to the water outlet pipe (7) by a water pump, and the cooled water is sent to the cooling water pipe (14) by the water outlet pipe (7) for circulating cooling;
step three: and starting an exhaust fan (12), sucking the gas passing through the second cooling box (9) into an exhaust port (11), then feeding the cooled gas into the exhaust fan (12), and finally discharging the cooled gas from the exhaust fan (12), thus finishing the heat recovery operation of the exhaust gas of the whole side-blown smelting furnace.
