Embodiment 1

[0043] combine Figure 1-Figure 8 , this embodiment describes in detail the online emergency maintenance method of the molten salt storage tank of the present invention, which includes the following steps:

[0044] S11: arrange sensor 1 outside the tank wall and / or tank bottom of the molten salt storage tank, and sensor 1 detects whether the molten salt leaks;

[0045] S12: When the sensor 1 detects that the molten salt leaks, inject a refrigerant medium to the leakage area where the sensor 1 is located, and block the leakage wound;

[0046] S13: Repair the leakage area.

[0047] Wherein, S11 is specifically: dividing the tank wall 3 and / or tank bottom 4 of the molten salt storage tank into grids, and arranging a sensor 1 at the center of each grid, and the sensor 1 is arranged in the insulation layer 2 of the molten salt storage tank , the distance between the sensor 1 and the tank wall 3 and / or tank bottom 4 of the molten salt storage tank is 5cm, there is a large temperat...

Embodiment 2

[0056] This embodiment describes in detail the online emergency maintenance system for molten salt storage tanks of the present invention, which is a system for implementing the above maintenance method, including: sensors, refrigerant injection devices and repair devices. Among them: the sensor is as figure 2 In the array arrangement shown, the area occupied by each sensor is 1m×1m, each sensor has a number, and the location of the leakage area can be accurately determined according to the number; the refrigerant injection device is used when the sensor detects a leak, Spray the refrigerant medium to the leakage area, and the refrigerant vaporizes, taking away the heat of the tank and molten salt near the leakage point, causing the molten salt near the leakage wound to solidify, forming such a shape on the inner and outer walls. Figure 5-6 The first solidified salt block 5 and the second solidified salt block 6 shown prevent further leakage of the molten salt; the cleaning ...

Abstract

The invention discloses an online emergency maintenance method and an online emergency maintenance system of a molten salt storage tank. The method comprises the steps of arranging sensor(s) on the wall and / or at the outer side of the bottom of the molten salt storage tank, wherein the sensor(s) is / are used for detecting whether the molten salt has leakage or not; when the sensor(s) detect(s) that the molten salt has leakage, spraying a refrigerating medium onto the leakage area(s) where the sensor(s) is / are arranged to block the leakage opening(s); repairing the leakage area(s). The system comprises the sensor(s), a refrigerating medium spray device and a repairing device, wherein the sensor(s) is / are arranged in heat insulation layer(s) of the molten salt storage tank; the heat insulation layer(s) is / are arranged on the wall and / or at the outer side of the bottom of the molten salt storage tank; the refrigerating medium spray device is used for spraying the refrigerating medium onto the leakage area(s) when the molten salt storage tank has leakage; the repairing device is used for repairing the leakage area(s). By adopting real-time monitoring, in-place blocking and online repairing, the online emergency maintenance method and the online emergency maintenance system of the molten salt storage tank are low in cost, less in loss and free from pollution.

Description

technical field [0001] The invention relates to the technical field of molten salt storage maintenance, in particular to an online emergency maintenance method and system for molten salt storage tanks. Background technique [0002] Solar thermal storage power generation is an important development direction of solar energy utilization in the future, and it is also a strategic direction for sustainable development. It can achieve continuous and stable power generation and undertake basic power loads. It will replace traditional dynamic power generation in the future. It has zero emissions, no pollution, Load stability and other advantages, which cannot be achieved by traditional nuclear power, wind power and photovoltaic power generation. [0003] At present, in order to overcome the shortcomings of discontinuous and unstable sunlight, most solar thermal power stations are equipped with heat storage systems, which are the conditions for realizing 24-hour continuous power gene...
