Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 As shown, the present invention provides a liquid storage tank utilizing a temperature difference power supply to realize internal fluid drive. The tank space of the liquid storage tank is composed of the peripheral side wall 1 of the tank body, the tank top cover 2, the tank bottom plate 3 and the tank body The inner ring side wall 4 is surrounded; the horizontal section of the box space is a centrally symmetrical annular polygon, circular ring, polygon or circle; the inner ring side wall 4 of the box is surrounded by a ventilation channel 15 outside the box.

[0033] Such as Figure 1 to Figure 4 As shown, part of the wall of the outer side wall 1 of the box is one or more temperature difference power supplies 9 of the outer side wall of the box, and part of the wall of the box top cover 2 is one or more top...

Abstract

The storage of a liquid is usually static in a nuclear power plant; and a storage box only needs to satisfy leak tightness, homoiothermy and accessibility. If stirring and mixing of the stored liquid can be realized in a certain special application occasions, and especially under an accident condition, the preset function of the stored liquid can be strengthened greatly; but the power needed by the stirring and mixing function is usually difficult to obtain in time. The invention belongs to a liquid storage box design, and particularly relates to a liquid storage box for realizing internal fluid driving by utilizing a temperature difference power source. Multiple groups of temperature difference power sources are arranged on a wall body, a top cover and a bottom plate of the storage box; and under the accident condition of the nuclear power plant, the temperature difference power sources enable a reactor to release heat abnormally and change the heat into an electric energy so as to drive a shielding pump and a draught fan both integrated in the storage box to stir and mix the stored liquid.

Description

technical field [0001] The invention belongs to the design of a liquid storage tank, in particular to a liquid storage tank which utilizes a temperature difference power supply to realize internal fluid drive. Background technique [0002] In nuclear power plants, the storage of liquids is usually static, and the storage tanks only need to meet the requirements of tightness, constant temperature and accessibility. However, in some special applications, especially in accident conditions, if the storage liquid can be stirred, the preset function of the storage liquid will be greatly enhanced, but the power required for this mixing work is usually difficult to timely acquired. [0003] Take the third-generation nuclear power plant AP1000 designed by Westinghouse Corporation of the United States as an example. Its main advantage and typical feature is its passive safety system. The in-containment refueling water tank (IRWST) of AP1000 is an important intermediate heat sink in ...
