Description
Technical Field
The invention relates to a high-efficiency heat exchange device of a passive containment cooling system, in particular to a containment built-in high-efficiency heat exchanger adopting a gas storage compartment type.
Background
In recent years, along with the shortage of world energy, many clean energy sources are rapidly developed, wherein nuclear energy is the rapidly developed clean energy source, and the nuclear energy has a vital role in meeting the electric power requirements of China, optimizing the energy structure and reducing the environmental pollution. However, the nuclear energy brings many risks while bringing clean and efficient energy to human beings. How to enhance the safety of nuclear power plants has been a focus of attention of related researchers. In order to relieve serious consequences of accidents and effectively guarantee the safety of a nuclear power plant, a passive containment cooling system is widely applied to the third-generation nuclear power technology.
The passive containment cooling system generally comprises a containment built-in heat exchanger, a containment external heat exchange water tank, and pipelines and valves for connecting the heat exchange water tank and the heat exchanger. When a bevel accident occurs to the reactor, a large amount of high-temperature and high-pressure steam is generated in the containment vessel and contacts with a heat transfer pipe of the built-in heat exchanger to form a condensation heat exchange process, the water temperature of an upper pipe section of the heat exchanger is continuously increased, and the density is continuously reduced. Natural circulation flow is formed under the driving of the difference of gravity of the upper pipe section and the lower pipe section, so that the heat inside the containment vessel is effectively led out, and the excess temperature and the excess pressure of the containment vessel are prevented.
When an accident occurs in the reactor, in order to enhance the heat deriving capacity in the containment, a heat exchange strengthening measure of the containment passive heat exchanger needs to be considered. In the condensation heat exchange process, a small amount of non-condensable gas has an obvious inhibiting effect on condensation heat exchange, so that the reduction of high-concentration air near the heat transfer pipe and in the air space above the containment can be considered to enhance the heat exchange capacity of the heat exchanger. In the prior patents, some inventions only aim at the long-term operation capacity of a heat exchange water tank, and the heat exchange capacity of a heat exchanger arranged in a containment cannot be considered. For example, patents with patent numbers CN201611061901.7 and CN201810662023.7 all design a reinforced heat exchange structure of a novel heat exchange water tank, so that the passive containment cooling system can derive heat in the containment for a long time. However, it is also important to enhance the heat exchange capacity of the internal heat exchanger itself.
Therefore, it is necessary to invent a containment built-in efficient heat exchanger adopting a gas storage compartment type, which enhances the heat exchange capability of the heat exchanger by collecting and storing high-concentration air around a heat transfer pipe and in the whole upper space of the containment, so as to efficiently take away a large amount of steam generated when a breach accident occurs in the containment. The over-temperature and over-pressure in the containment vessel are prevented, and the safe operation capability of the nuclear power station is improved.
