[0027] Such as figure 1 , A dual-injection molten iron desulfurization device, including a desulfurization vehicle and a molten iron tank 2 located above the desulfurization vehicle; and also includes a lifting agitating spray device. The stirring and spraying device is located directly above the molten iron tank 2, and includes a vertical stirring shaft 3 and a stirring blade 4 located at the lower end of the stirring shaft 3. The stirring blade 4 can be in the molten iron at the bottom of the molten iron tank 2 and the space above the molten iron tank 2. Lift between.
[0028] Such as image 3 The stirring and spraying device further includes an air inlet pipe 5 and a plurality of horizontal L-shaped nozzles 6. The stirring shaft 3 is provided with a cavity along the axial direction; the air inlet pipe 5 is embedded in the cavity of the stirring shaft 3. The multiple L-shaped nozzles 6 are symmetrically arranged on the outer periphery of the intake pipe 5 along the center of ...
