Embodiment 1
[0025] like Figure 1-2 As shown, the copper plate tuyere cover of the blast furnace that can spray multiple fuels in this embodiment includes the outer cover 1, the inner cover 2 and the flange 3, the outer cover 1 is set outside the inner cover 2, and the front end of the outer cover 1 is connected to the inner cover 2. The front end is nested and fixed by the flange 3, the outer sleeve 1, the inner sleeve 2, and the flange 3 are connected to form a water cooling pipeline 5, the bottom of the water cooling pipeline 5 is provided with a deflector 6, and the water cooling pipeline 5 is also provided with a spray pipe 7. The inlet 71 of the blowing pipe 7 is connected to the flange 3, the outlet 72 of the blowing pipe 7 is connected to the inner sleeve 2, the blowing pipe 7 is J-shaped and the outlet 72 of the blowing pipe 7 extends from the water cooling pipe 5 into the inner wall of the tuyere sleeve 4 .

Embodiment 2
[0033] The difference between the blast furnace copper plate tuyere sleeve capable of injecting multiple fuels in this embodiment and that of Embodiment 1 is that:
[0034] The angle between the direction of the outlet of the blowing pipe and the plane where the inner wall of the tuyere sleeve is located is 120°. Through this setting, various pressure recoils in the tuyere sleeve can be avoided, ensuring that the angle at which the fuel is sprayed from the outlet of the injection pipe will not be recoiled by the hot air pressure passing through the inner wall of the tuyere sleeve or other pressures in the blast furnace, and the efficiency of using the tuyere sleeve can be improved. safety.
Embodiment 3
[0036] The difference between the blast furnace copper plate tuyere sleeve capable of injecting multiple fuels in this embodiment and that of Embodiment 1 is that:
[0037] The angle between the direction of the outlet of the blowing pipe and the plane where the inner wall of the tuyere sleeve is located is 130°. Through this setting, various pressure recoils in the tuyere sleeve can be avoided, ensuring that the angle at which the fuel is sprayed from the outlet of the injection pipe will not be recoiled by the hot air pressure passing through the inner wall of the tuyere sleeve or other pressures in the blast furnace, and the efficiency of using the tuyere sleeve can be improved. safety.
