Embodiment Construction
[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] Please refer to figure 1 , 2 , a safe heat exchange system for a deep well low temperature nuclear heating reactor provided by the present invention includes three sets of loop circulation systems, the first loop circulation system includes a deep water pool 1 , a main heat exchanger 2 and a first drive pump 3 . The depth of the deep water pool 1 is 10-40m, and the core 4 of the nuclear reactor is arranged at the bottom of the pool as the heat source of the whole heating system. During operation, water is stored in the deep water pool, heated by the core 4 to raise the temperature, and then the main heat exchanger 2 exchanges heat with the water in the deep water pool 1 .
[0025] The second loop circulation system is compo...

The invention discloses a safety heat exchange system of a deep well low-temperature nuclear heating reactor. The safety heat exchange system comprises a deep water pool. A reactor core is arranged at the bottom of the pool. A first loop circulation system is composed of the deep water pool, a main heat exchanger and a first drive pump. The main heat exchanger is used for being subjected to heat exchange with water in the deep water pool. A second loop circulation system is composed of the main heat exchanger, an intermediate heat exchanger and a second drive pump, and the intermediate heat exchanger is used for being subjected to heat exchange with heat exchange media in the main heat exchanger. A third loop circulation system is composed of the intermediate heat exchanger, a third drive pump and a heat supply network. During work, the pressure of water in the second loop circulation system is larger than that of water in the first loop circulation system and smaller than that of water in the third loop circulation system. A buffer water tank is connected to a pipe of the second loop circulation system through a pressure valve, a liquid level meter is arranged in the buffer water tank, the output end of the liquid level meter is connected with a controller, and the output end of the controller is connected with an alarm. The system can avoid nuclear leak and is safe and reliable.
Description
technical field [0001] The invention relates to the field of nuclear energy heat supply, in particular to a safe heat exchange system for a deep well low-temperature nuclear energy heat supply pile. Background technique [0002] Nuclear energy heating is a centralized urban heating method that uses the energy generated by nuclear fission as the heat source. It is a new way to solve urban energy supply, reduce transportation pressure and eliminate environmental pollution caused by burning coal. [0003] The existing deep well low-temperature nuclear energy heating system includes a deep water pool, and a nuclear reactor core is arranged at the bottom of the pool, and the core is used as a heat source of the heating system to heat the pool water in the deep water pool. After the pool water is heated, it exchanges heat with the heat exchanger and finally enters the urban heating network. [0004] However, due to the stability of the pipeline itself, leakage often occurs. Unl...
