[0022] Example

[0023] See also Figures 1 to 4 In the embodiment of the utility model, a high-power steam turbine auxiliary machine includes a base plate 1, a base plate 1, a steam turbine body 3 is arranged on the top of the base plate 1 through a mounting frame 2, and the steam turbine body 3 can be used for corresponding power generation work. A fixing plate 4 is also arranged on the top of the mounting frame 2, and a shell 6 is arranged on the top of the fixing plate 4 through a support leg 5. The steam turbine body 3 is connected to the shell 6 through a steam outlet pipe 7. At this time, the steam outlet pipe 7 is used to introduce the generated residual steam into the shell 6, so as to facilitate its subsequent processing work. A valve 8 is also arranged on the steam outlet pipe 7. Under the action of the valve 8, the switch of the steam outlet pipe 7 can be controlled, thereby ensuring the use efficiency of the steam outlet pipe 7.

[0024] A condenser 10 is also provided inside the shell 6. Under the action of the condenser 10, the remaining steam entering the shell 6 through the steam outlet pipe 7 can be condensed, thereby condensing the steam. A drain pipe 13 is also provided on the shell 6. Under the action of the drain pipe 13, the condensed water can be discharged, thereby ensuring the use efficiency of the device. A filter screen 9 is also provided inside the shell 6. At this time, under the action of the filter screen 9, the impurities inside the condensed water can be filtered, thereby reducing the situation where the drain pipe 13 is blocked due to excessive impurities in the condensed water, thereby ensuring the use efficiency of the device. A refrigerator 11 is also provided on the top of the shell 6. One end of the refrigerator 11 is connected to the liquid inlet end of the condenser 10, and the other end of the refrigerator 11 is connected to the liquid outlet end of the condenser 10. The refrigerator 11 is used to generate a cooled coolant and introduce it into the condenser 10, thereby ensuring the use efficiency of the condenser 10, thereby better condensing the discharged steam, thereby ensuring the use efficiency of the device.

[0025] An exhaust pipe 12 is also provided on the shell 6. Under the action of the exhaust pipe 12, the exhaust gas in the steam can be discharged, thereby realizing the separation of gas and steam, so that the device can better meet the needs of actual use. In actual use, when the turbine body 3 is working, the excess steam generated will enter the shell 6 through the exhaust pipe 7. At this time, under the action of the condenser 10, the steam can be condensed and the excess exhaust gas can be discharged through the exhaust pipe 12, thereby assisting the turbine body 3.

[0026] The outlet pipe 12 is also provided with a mounting plate 16, on which a filter sleeve 14 is provided, and on which an exhaust pipe 15 is provided. Under the action of the filter sleeve 14, the exhaust gas discharged from the outlet pipe 12 can be filtered, thereby reducing the impact of direct exhaust gas discharge on the environment, thereby ensuring the use efficiency of the device. The mounting plate 16 is also provided with a mounting shell, on which a plug rod 17 is slidably provided, and a block 18 used in conjunction with the plug rod 17 is provided on the side wall of the filter sleeve 14. Under the action of the plug rod 17 and the block 18, the filter sleeve 14 can be The installation is fixed, and it is also convenient for disassembly of the filter sleeve 14, and then it is convenient for replacement of the filter sleeve 14, thereby ensuring its filtering quality for exhaust gas. A limit plate is also provided on the plug rod 17, and a reset spring 19 is sleeved on the outer side of the plug rod 17. One end of the reset spring 19 is connected to the limit plate, and the other end of the reset spring 19 is connected to the inner wall of the mounting shell. At this time, under the action of the reset spring 19, the connection quality of the plug rod 17 and the socket is guaranteed, thereby ensuring the installation quality of the filter sleeve 14. A handle 20 is provided at the end of the plug rod 17, and the plug rod 17 can be moved under the action of the handle 20.

[0027] In actual use, when the turbine body 3 is working, the excess steam generated will first enter the shell 6 through the steam outlet pipe 7. Before the steam enters, the switch of the steam outlet pipe 7 can be controlled by the valve 8 to adjust the flow of the steam. After the steam enters the shell 6, it will contact the condenser 10, and the steam will contact the low-temperature coolant to be condensed into water. The condensed water will be filtered through the filter screen 9 to remove possible tiny impurities, and then discharged through the drain pipe 13. While the steam is condensed, the exhaust gas therein will be discharged through the exhaust pipe 12. Before the exhaust gas is discharged, it will first pass through the filter sleeve 14. The filter sleeve 14 can effectively filter out harmful substances in the exhaust gas and reduce the impact on the environment. The filtered exhaust gas is finally discharged into the atmosphere through the exhaust pipe 15. When the filter sleeve 14 needs to be replaced, it is only necessary to pull the plug rod 17 through the handle 20 to separate it from the block 18 on the side wall of the filter sleeve 14. When the plug rod 17 is completely separated from the block 18, the filter sleeve 14 can be removed and replaced. After the new filter sleeve 14 is installed, release the handle 20, and the reset spring 19 will push the plug rod 17 to reset it, so that it is reconnected with the block 18, thereby fixing the new filter sleeve 14.
