[0002] During the ore mining and processing process, transporting the ore outward through a slurry pump is a mining transportation method. As the slurry is transported downward, due to a certain drop in the pipeline, a certain gravitational potential energy will be generated. Generally, an energy dissipation device needs to be installed at the end to ensure the safety of the end. In this process, not only the potential energy generated during the transportation of the slurry is consumed in vain, but also additional electricity is required to operate the energy dissipation equipment, resulting in a certain waste of resources and even electricity shortage.

DETAILED DESCRIPTION
[0012] Embodiment 1: A slurry turbine power generation equipment, including an upper slurry pool 1, a slurry turbine 5, a generator and a lower slurry pool, wherein the upper slurry pool 1 is installed at a higher position than the slurry turbine 5, and the slurry turbine 5 is higher than the lower slurry pool 7. The upper part of the upper slurry pool 1 is fed with slurry through a pipeline, and the bottom is connected to the slurry inlet pipe 55 of the slurry turbine 5 through the main pipeline 2. The slurry turbine is a double runner 51, including a double runner 51, a fixed guide vane 52, a volute 53, a main shaft 54 and a bearing 57. The slurry inlet pipe 55 is connected to the inlet of the volute 53. The double runner 51 and the fixed guide vane 52 are installed in the center of the volute 53. The double runner 51 is installed on the main shaft 54. The main shaft 54 on one side is connected to the generator 6 through the bearing 57 and the coupling. In this embodiment, the generator 6 is a DC generator. Two slurry outlet pipes 56 are symmetrically arranged at the outlets on both sides of the volute 53, and the slurry outlet pipes 56 are connected to the upper part of the lower slurry pool 7 through the main pipeline 2. An outlet valve 3 is provided at the outlet of the upper slurry pool 1, and a check valve 4 is installed before the slurry inlet pipe 55 and after the slurry outlet pipe 56 of the slurry turbine 5, and a safety valve 8 and an emergency stop valve 9 are provided between the outlet valve 3 and the check valve 4 before the slurry inlet pipe 55. A bypass pipeline is also provided, and both ends of the bypass pipeline are connected to the outside of the two check valves, and a bypass flow regulating valve 10 is provided on the bypass pipeline.
[0013] The upper slurry pool 1 and the lower slurry pool 7 are used to store slurry, the main pipeline 2 is used to transport slurry, the outlet valve 3 is used to open or close the outflow of the upper slurry pool, and the inspection valve 4 is used for the subsequent maintenance and repair of the slurry turbine. The slurry turbine 5 not only plays the role of energy dissipation at the end of slurry transportation, but also can convert the gravitational potential energy of the slurry into mechanical energy to drive the operation of the DC generator. Since the density of slurry is greater than that of water, its power generation power under the same flow rate is greater than that of the turbine with the same amount of water. Because slurry is mostly corrosive, the turbine flow surface must be made of wear-resistant and corrosion-resistant materials. In addition, due to the high density of slurry, the axial stress generated by the slurry flowing in the slurry turbine 5 is large, so a slurry turbine 5 with a symmetrical arrangement of two impellers is used, which can offset the axial force, reduce the stress and wear of the bearings and seals, and improve the basic stress conditions. Since the slurry has a large abrasive effect on the flow surface of the equipment, in order to ensure the service life of the equipment and reduce the maintenance frequency, there is no flow adjustment for the slurry flow through the machine, that is, there is no movable guide vane, and the machine can be fully flowed. For the instability of power changes, a DC generator or an asynchronous generator is used to match to meet the power demand. Fixed guide vanes are installed between the volute and the runner to improve the power generation efficiency. A safety valve and an emergency shut-off valve 9 are set in front of the slurry turbine to protect the conveying pipeline and power generation equipment. When the equipment is under maintenance, the bypass pipeline and bypass flow regulating valve 10 can temporarily convey the slurry.
[0014] The slurry enters from the slurry inlet pipe 55 and first reaches the volute 53, rotates inside the volute, passes through the fixed guide vane 52, and then drives the double impeller 51 to rotate. The main shaft 54 and the coupling 8 transmit the mechanical energy to the generator 6, and the generator 6 converts the mechanical energy into electrical energy. Finally, the slurry flows out from the slurry outlet pipes 56 on both sides.
