Above-mentioned coolant inlet pipe is the inverted U structure, is subjected to atmospheric contamination to avoid influent quality.Further, place, the inverted U position of described coolant inlet pipe is provided with siphon destructing tube, to avoid the generation of siphon accident.
Further, the water inlet of above-mentioned coolant inlet pipe is arranged at the bottom of water tank tank skin.
Further, the top outer rim of above-mentioned water tank is provided with maintenance track, so that construction and maintenance.
The utility model enables to be fit to be designed to big volume specification such as 3000m by adopting said structure
3, 3600m
3Sweet-water tank, can satisfy single-machine capacity and be 600MW and above thermal electric generation unit and single-machine capacity and be the day-to-day operation water consumption requirement of 1000MW and above nuclear power generating sets, and number of devices is less, floor area is less, has reduced the overall cost of ownership of power plant.

Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
The specific embodiment
As shown in figure 1 to figure 13, sweet-water tank described in the utility model, identical substantially with the structure of existing sweet-water tank, the keystone configuration improvement is at water tank tank skin 1, water tank bottom plate 2, water tank top board 3 and coolant inlet pipe 4.
As shown in Figure 3 and Figure 4, water tank bottom plate 2 of the present utility model and water tank top board 3 adopt tie welding mode shown in Fig. 5 a, Fig. 5 b and Fig. 5 c integral body that is formed by connecting by some steel plates 6 respectively.
To shown in Figure 8, water tank tank skin 1 of the present utility model adopts the butt welding mode to be formed by connecting by some curved plates 11 as Fig. 6.The butt welding mode structure of tank skin 11 connection modes employings of curved plate longitudinally shown in Fig. 9 a and Fig. 9 b; 11 connection modes of the curved plate of tank skin hoop adopt the butt welding mode structure shown in Figure 10 a and Figure 10 b.
As shown in figure 11, coolant inlet pipe 4 of the present utility model is the inverted U structure, and the water inlet 41 of coolant inlet pipe 4 is arranged at the bottom of water tank tank skin; And place, the inverted U position of coolant inlet pipe 4 is provided with siphon destructing tube 42.
As Fig. 1 and Fig. 2, and Figure 12 and shown in Figure 13, tank top outer rim of the present utility model also is provided with maintenance track 5.
The utility model is fit to be designed to big volume specification sweet-water tank, as 3000m
3, 3600m
3To satisfy single-machine capacity is that 600MW and above thermal electric generation unit and single-machine capacity are the day-to-day operation water consumption requirement of 1000MW and above nuclear power generating sets, and compare with the sweet-water tank of little volume specification, have the advantage that number of devices is less, floor area is less and overall cost of ownership is lower; And the structural improvement of coolant inlet pipe, vulnerable to pollution, draining be not thoroughly and characteristics such as water tank effective volume degree of utilization height then can to make influent quality; Also have, the setting of maintenance track provides convenience then for construction and maintenance.
