Embodiment Construction

[0049] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0050] Such as figure 1 and figure 2 As shown, in the present invention, the selective inflow water temperature stabilizing device comprises: a reservoir 5, a clapper gate inflow device and a water intake building 6, and the clapper gate inflow device and a water intake structure 6 are respectively arranged at the bottom of the reservoir 5 On different sides, water intake culvert pipes are connected to the bottom of the water intake structure.

[0051] The reservoir 5 includes: a No. 1 reservoir 12 , a slope transition section 14 and a No. 2 reservoir 13 . The volume under the water surface of the reservoir 5 during normal operation is such that the clapboard door does not enter the flow, and the exchange time of the water body in the reservoir is longer than the general extreme high temperature duration when th...

Abstract

The invention discloses a selective inlet water temperature stabilizing device. The selective inlet water temperature stabilizing device comprises a water reservoir, a clapper door inflow device and a water taking building, wherein the clapper door inflow device and the water taking building are respectively arranged on the two sides of the water reservoir; and the bottom of the water taking building is connected with a water taking culvert pipe. The invention also discloses a water temperature value simulating and forecasting method. According to the invention, external seawater used as a power plant safety plant water source flows in through the device while higher water level and lower temperature of the external seawater are obtained; and the external seawater is conveyed into a safety plant cooling water taking pump house after cold water and hot water are sufficiently mixed and the surface is cooled; therefore, the temperature of the water taken from the safety plant water is obviously reduced while being compared with the variation gradient and the peak value of the water temperature at the external seawater taking opening so that the high peak value of the water taking temperature can be stabilized, the reduction amplitude of the safety plant water temperature can be also forecasted after using the system and the device, and design parameters are provided for building the selective water temperature stabilizing device.

Description

technical field [0001] The invention relates to the technical field of intake and drainage of cooling water, in particular to a selective inflow water temperature stabilization device and a water temperature numerical simulation prediction method thereof. Background technique [0002] Nuclear power plants built in coastal tidal waters mostly use seawater direct current cooling. For the safe plant water used to cool the core components of nuclear power plants, the water intake temperature is an important factor affecting the safe operation of nuclear power plants, and there is a threshold limit in design. Affected by coastal economic development and global warming, the water intake temperature of nuclear power plants in coastal tidal waters is facing an increasing trend, especially the risk of abnormally high water intake temperature due to frequent abnormal weather. [0003] When nuclear power plants in coastal tidal waters adopt the seawater direct-flow cooling method, the ...
