Description

Technical Field

[0001] This application relates to the technical field of generators, and in particular to a steam turbine generator. Background Technology

[0002] During operation, steam turbine generators generate a significant amount of heat due to electromagnetic induction, mechanical friction, and other factors. If this heat is not dissipated effectively and promptly, the internal temperature of the unit will rise. Existing cooling systems often suffer from insufficient heat dissipation efficiency and uneven heat distribution. For example, improper design of the cooling medium flow path may result in inadequate cooling of certain high-heat areas, or insufficient heat exchange contact between heat dissipation components and heat-generating components. This not only affects the operating efficiency of the steam turbine generator, leading to a decrease in output power, but also accelerates the aging of insulation materials and the wear of mechanical components due to prolonged high-temperature operation, shortening the equipment's lifespan. It may even cause insulation breakdown, component deformation, and other faults, seriously threatening the safe and stable operation of the unit. Therefore, developing a highly efficient and stable heat dissipation structure to address the shortcomings of existing cooling systems has become a key requirement for improving the operating performance and reliability of steam turbine generators.

[0004] The steam turbine generator provided in this application adopts the following technical solution:

[0005] A steam turbine generator includes a steam turbine generator body. An exhaust fan is installed at one end of the steam turbine generator body, and an induced draft fan is installed at the other end. An air inlet pipe is connected to the induced draft fan. The air inlet pipe passes through the side wall of the steam turbine generator body shell. Multiple air outlet pipes are fixedly connected and connected to the air inlet pipe. The air outlet end of the air outlet pipe passes through the side wall of the steam turbine generator body and is placed inside the steam turbine generator body. Multiple branch air pipes are fixedly connected to the arc-shaped side wall of the air outlet pipe, and the branch air pipes face the interior of the steam turbine generator body. A water cooling assembly is provided in the middle section of the steam turbine generator body.

[0006] By adopting the above technical solution, the external gas can flow inside the turbine generator body through the cooperation of exhaust fan and induced draft fan, thereby cooling the turbine generator body. At the same time, the air force is dispersed through the air distribution pipe, making the overall cooling of the turbine generator more smooth. The overall temperature of the turbine generator can be controlled by the water cooling component, thereby allowing the turbine generator to operate within a suitable temperature range and ensuring its power generation efficiency.

[0007] Optionally, among the two adjacent air outlet pipes, the diameter of the upper air outlet pipe is smaller than the diameter of the lower air outlet pipe.

[0008] By adopting the above technical solution, the air volume of the upper air outlet duct can be reduced, making the airflow and discharge more uniform.

[0009] Optionally, in two adjacent air outlet pipes, the upper air outlet pipe is longer than the lower air outlet pipe.

[0010] By adopting the above technical solution, the lower air outlet position can be extended, thereby increasing the air distribution range.

[0011] Optionally, the orientation of the air distribution ducts may vary.

[0012] By adopting the above technical solutions, the distribution range and uniformity of wind power can be improved.

[0013] Optionally, the air inlet pipe is arranged in an arch shape within the steam turbine generator body.

[0014] By adopting the above technical solutions, the uniformity of wind force distribution can be improved.

[0015] Optionally, the water-cooling assembly includes a water-cooling pipe that surrounds the inner wall of the turbine generator body. The turbine generator body is provided with a water storage tank and a pump body. The water-cooling pipe is connected to the water storage tank. The pump body is installed on the water-cooling pipe. The end of the water-cooling pipe away from the water storage tank is connected to a collection tank, which is placed outside the turbine generator body.

[0016] By adopting the above technical solution, water flowing out of the water storage tank can be pumped through the cold water pipe and absorbed heat during the flow. The cold water can be recovered by collecting the tank.

[0017] Optionally, a foundation pit is provided on the ground where the steam turbine generator body is located, and the collection box and the water storage tank are both placed in the foundation pit.

[0018] By adopting the above technical solution, the impact of external temperature on the two water tanks can be reduced by setting up the foundation pit, while also reducing the area occupied by the equipment.

[0019] Optionally, the water-cooled pipe is arranged in a disc shape at the bottom of the turbine generator body.

[0020] By adopting the above technical solutions, the distribution area of ​​cold water pipes can be increased, ensuring cooling efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The external air can flow inside the turbine generator body through the combination of exhaust fans and induced draft fans to cool the turbine generator body. At the same time, the air force is dispersed through the air distribution pipes, making the overall cooling of the turbine generator more efficient.
