[0028] Example 1

[0029] like Figure 1 As shown, this utility model provides a power generation device using high-pressure blast furnace molten iron jet. The hearth of the blast furnace is provided with an iron tap hole 11 that connects the interior to the iron tap frame 1. Molten iron in the hearth can be jetted out from the iron tap 3 on the iron tap frame 1 through the iron tap hole 11 to form an iron flow 2.

[0030] The power generation device includes a molten iron residual pressure conversion unit, a generator 6, and an electrical storage unit;

[0031] The molten iron pressure conversion section includes a support body, a movable base 12, a fixed beam 13, and a track 14;

[0032] The track 14 is laid on the side of the ditch between the two main ditches in front of the taphole 3 on the blast furnace; the movable base 12 is movably installed on the track 14; the supporting body is fixedly connected to the movable base 12 through the fixed beam 13; the movable base 12 is used to drive the supporting body to move back and forth along the track 14 through the fixed beam 13, so that the supporting body approaches or moves away from the taphole 3.

[0033] The supporting structure includes a diversion pipe 4 and a high-temperature resistant water turbine 5. The high-temperature resistant water turbine 5 is fixedly installed in the diversion pipe 4, and the runner is located inside the diversion pipe 4. The inlet of the diversion pipe 4 can be connected to the iron tap 3, so that the iron flow 2 injected into the diversion pipe 4 impacts the runner of the high-temperature resistant water turbine 5, converting the energy of the iron flow 2 into mechanical energy. The main shaft of the high-temperature resistant water turbine 5 is connected to the rotor of the generator 6, transferring the mechanical energy generated by the rotation of the runner of the high-temperature resistant water turbine 5 to the generator 6 for power generation. The bottom of the diversion pipe 4 is connected to a molten iron discharge pipe 15, and the bottom outlet of the molten iron discharge pipe 15 is located above the main trench, used to discharge the molten iron after impacting the runner of the high-temperature resistant water turbine 5 into the main trench.

[0034] The energy storage unit is electrically connected to the generator 6 and is used to store the electrical energy generated by the generator 6.

[0035] Furthermore, the movable base 12 is slidably mounted on the track 14 via rollers.

[0036] Furthermore, the high-temperature resistant water turbine 5 can be an existing water turbine, and its internal structure and working principle will not be described in detail in this application; the outer shell and the runner of the high-temperature resistant water turbine 5 are both made of high-temperature resistant alloy and coated with Al2O3-SiC-C refractory material on the surface.

[0037] Furthermore, the energy storage unit includes a transformer 7 and a battery 8. The transformer 7 is electrically connected to the generator 6 and the battery 8 respectively, and is used to convert the voltage generated by the generator 6 into the charging voltage of the battery 8 and then deliver it to the battery 8 for storage. The generator 6, the transformer 7 and the battery 8 can all be existing products, and will not be described in detail in this application.

[0038] Furthermore, the battery 8 is electrically connected to end users who require electricity, including furnace equipment, lighting, and emergency energy storage devices, and the battery 8 is able to supply power to the end users.

[0039] Furthermore, the main trough includes a front section 9 near the blast furnace and a rear section 10 located behind the front section 9. The depth of the rear section 10 is greater than the depth of the front section 9. The bottom outlet of the molten iron discharge pipe 15 is located above the rear section 10. Molten iron after impacting the runner of the high-temperature turbine 5 is discharged into the rear section 10. Deepening the rear section 10 provides space for the molten iron discharge pipe 15 to discharge molten iron, preventing the molten iron discharge pipe 15 from being damaged by contact with the molten iron in the main trough.

[0040] When the high-pressure blast furnace molten iron jet power generation device described in this utility model is working, after the iron flow 2 stabilizes by opening the tap 3, the supporting body is moved to a suitable position in front of the tap 3 by using the movable base 12 on the track 14, so that the inlet of the diversion pipe 4 is connected to the tap 3, so that the iron flow 2 can just completely enter the diversion pipe 4. The iron flow 2 directly impacts the rotor of the high-temperature resistant water turbine 5 and the mechanical energy generated by the rotor rotation is transferred to the generator 6 to generate electricity through the main shaft of the high-temperature resistant water turbine 5. The molten iron after the iron flow 2 impacts the rotor is discharged into the rear section 10 of the main ditch through the molten iron discharge pipe 15. The generator 6 transmits the generated electrical energy to the battery 8 for storage through the transformer 7. The battery 8 is connected to end users such as furnace front equipment, lighting, and emergency energy storage devices, and can provide power to end users when needed.

[0041] The present invention provides a power generation device utilizing high-pressure blast furnace molten iron jet. This device generates electricity by safely and rationally utilizing the impact energy of the molten iron jet from the taphole, and stores the electricity for use in furnace equipment operation and lighting. This fully utilizes the energy contained in the molten iron jet, while avoiding erosion of the main channel and dust cover by the high-pressure molten iron jet, significantly reducing the cost of manual operation and maintenance. It has important application significance.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
