It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, an embodiment of the present invention provides a boiler rapid and emergency cooling system, which includes a boiler 1, a device 2, a heat conduction pipeline 3 connecting the boiler 1 and the device 2, and a main pump 4 disposed on the heat conduction pipeline 3, and meanwhile, the cooling system is further provided with a replacement module, the replacement module specifically includes a high-level tank 5 and a low-level tank 6, and both the high-level tank 5 and the low-level tank 6 are communicated with the heat conduction pipeline 3 through a replacement pipeline 7. Wherein, the high-level tank 5 is arranged at the highest position of the cooling system, the low-level tank 6 is arranged at the lowest position of the cooling system, and the low-level tank 6 is arranged below the ground in the embodiment because large-scale equipment such as the boiler 1 and the like are all arranged on the ground. The displacement medium is arranged in the high-level tank 5, the heat conduction medium is arranged in the heat conduction pipeline 3, the heat conduction medium and the displacement medium are heat conduction oil in the embodiment, the heat conduction oil prestored in the high-level tank 5 is cold oil, and the initial state in the low-level tank 6 is an empty tank. The joints of the high-level tank 5, the low-level tank 6 and the heat conducting pipeline 3 are provided with valves 8.

When the system needs to be cooled, the valve 8 of the low-level tank 6 is firstly opened, and the hot oil of the whole system flows into the low-level tank 6 to be stored under the action of gravity as the low-level tank 6 is arranged at the lowest position; then the valve 8 of the low-level tank 6 is closed, the valve 8 of the high-level tank 5 is opened, the high-level tank 5 is arranged at the highest position, so that the cold oil in the high-level tank flows through the heat conducting pipeline 3 and the whole system under the action of gravity, the temperature of the boiler 1, the equipment 2 and the like can be quickly reduced to about 30 ℃, the boiler is cooled and can be stopped to leave, and the hot oil stored in the low-level tank 6 can be slowly cooled to the room temperature. Therefore, the cooling mode of replacing cold oil and hot oil is adopted, and the waiting time is saved. Under the power failure state, the flow of the heat conduction oil is driven by gravity, so that the system does not need to consume excessive energy, and the technical effect of rapid cooling can be achieved.

In order to recycle the heat conducting oil cooled in the low-level tank 6, a return pipeline 9 is further arranged between the low-level tank 6 and the high-level tank 5 in the embodiment, and a return pump 10 is arranged on the return pipeline 9. The heat conducting oil in the low-level tank 6 is sent back to the high-level tank 5 through the reflux pump machine 10 to be pre-stored. Therefore, the system is provided with two groups of heat conducting oil, wherein one group of heat conducting oil is positioned in the heat conducting pipeline 3 to normally work for heat transfer, and the other group of heat conducting oil is stored in the replacement module. When cooling is needed, hot oil enters the low-level tank 6, cold oil enters the heat conduction pipeline 3 from the high-level tank 5 to complete replacement, and the hot oil in the low-level tank 6 returns to the high-level tank 5 after being cooled.

In the present embodiment, the volume of the high-level tank 5 is equal to the sum of the volumes of the pipeline of the boiler 1, the pipeline of the equipment 2 and the heat conducting pipeline 3, so that the cold oil in the high-level tank 5 can just replace the hot oil in the working system, and the volume of the low-level tank 6 is larger than that of the high-level tank 5 so as to leave a certain margin and ensure that the hot oil in the working system can be completely emptied.
