Embodiment 1
[0046] This embodiment provides a specific implementation of the secondary circuit flushing system of the high temperature gas-cooled reactor, such as figure 1 As shown, the flushing system includes a steam turbine 1 , a condenser 2 , a condensate pump 4 , a deaerator 6 , a feed water pump 7 and a steam generator 8 . The steam turbine 1 communicates with the condenser 2, the condenser 2 communicates with the condensate pump 4 through a first pipeline 18, and the condensate pump 4 communicates with the deaerator through a second pipeline 19. 6 is communicated, the deaerator 6 is communicated with the feed water pump 7 through the pipeline, the feed water pump 7 is communicated with the steam generator 8 through the third pipeline 20, and the steam generator 8 is communicated through the fourth pipe The road 21 communicates with the steam turbine 1 . A fifth pipeline 22 is communicated between the third pipeline 20 and the condenser 2, and the fifth pipeline 22 is connected to ...
Embodiment 2
[0054] This embodiment provides a specific implementation of the flushing method, using the flushing system in Example 1, including the following steps: closing the fourth valve 13 to isolate the finishing device 5, closing the first valve 14 and the second valve 15 to isolate the Steam generator 8, close the third valve 16 to isolate the steam turbine 1, open the trap valve 17; start the condensate pump 4, so that the condensed water in the condenser 2 passes through the first pipeline 18 and the second pipeline 19 to the deaerator 6 , and then start the feed water pump 7 to return the feed water in the deaerator 6 to the condenser 2 through part of the third pipeline 20 and the fifth pipeline 22, so as to realize the cold circulation flushing of the secondary circuit water system; start the electric boiler 9, A part of the steam generated by the electric boiler 9 enters the condenser 2 through the steam trap 17, and flushes the fourth pipe in a hot state. At the same time, th...
