Fig. 1 is the structure of a kind of rinse-system for clearing up local sedimentation in the nuclear power plant that the present invention provides
Schematic diagram；
Fig. 2 is the flow chart of a kind of method clearing up local sedimentation in the nuclear power plant that the present invention provides.
Detailed description of the invention
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
As it is shown in figure 1, be designed with demineralized water workshop 13 in usual nuclear power plant, demineralized water workshop 13
Pretreating process typically uses hyperfiltration treatment, and the waste water after hyperfiltration treatment is used for rinsing in nuclear power plant's pump house
Recirculated water and essential service water system, recirculated water and essential service water system in part pipeline be located at
In water plant 12.
A kind of rinse-system for clearing up local sedimentation in the nuclear power plant provided by the present invention, including being located at
Ultrafiltration Sewage treatment pond 1 in demineralized water workshop 13 and flush water pump 2, the entrance point of flush water pump 2
Being connected with ultrafiltration Sewage treatment pond 1, the port of export of flush water pump 2 is provided with flushing line 3.
