Efficient waste heat recovery device for steel smelting

Abstract

The utility model relates to the technical field of steel processing, and provides an efficient waste heat recovery device for steel smelting, which comprises a device shell, a liquid inlet pipe fixedly communicated with the top of the device shell, disinfectant filled in the device shell, and a water suction pump fixed on the side surface of the device shell, the water pumping end of the water pump fixedly communicates with the interior of the device shell, the end, away from the water pump, of the conveying pipe fixedly communicates with a spray head, and a purification box is arranged on the side, away from the spray head, of the device shell. The flow expanding assembly is matched with the rotating mechanism, the multiple mixing rods rotate to stir and scatter waste heat gas, and the waste heat gas circulates in the multiple curved circulation grooves in the scattering process, so that the waste heat gas evenly penetrates through the filter screen and the activated carbon filter screen to be filtered optimally; the phenomenon that waste heat gas directly blows certain parts of the filter screen and the activated carbon filter screen is avoided, the purified waste heat gas is transferred to the heating coil, and the heating coil rotates to achieve the effect of heating the disinfectant and stirring at the same time.
