Description
Technical Field
The invention relates to high-efficiency heat exchange equipment of a passive containment cooling system, in particular to a containment built-in high-efficiency heat exchanger adopting a gas storage compartment.
Background
Along with the shortage of world energy in recent years, many clean energy sources are rapidly developed, and nuclear energy is fast developed in all clean energy sources, so that the nuclear energy source has a vital role in meeting the power requirements of China, optimizing the energy structure and reducing environmental pollution. However, nuclear energy brings clean and efficient energy to human beings and also brings a plurality of risks. How to enhance the safety of nuclear power plants has been a focus of attention of related researchers. In order to alleviate the serious consequences of accidents and effectively ensure the safety of nuclear power plants, passive containment cooling systems are 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 the reactor has a groove accident, a large amount of high-temperature and high-pressure steam is generated in the containment, the steam is contacted with a heat transfer pipe of a built-in heat exchanger to form a condensation heat exchange process, the water temperature of the pipe section on the heat exchanger is continuously increased, and the density is continuously reduced. And natural circulation flow is formed under the driving of the weight difference of the upper pipe section and the lower pipe section, so that the heat in the containment can be effectively guided out, and the overtemperature and overpressure of the containment can be prevented.
In order to enhance the heat transfer capacity in the containment during an accident in the reactor, the enhanced heat exchange measures of the passive containment heat exchanger are considered. The small amount of non-condensable gas has obvious inhibition effect on condensation heat exchange in the condensation heat exchange process, so that the heat exchange capability of the heat exchanger can be enhanced by considering the reduction of high-concentration air near the heat transfer tube and in the upper air space of the containment. In the prior patents, some inventions only aim at the long-term operation capacity of the heat exchange water tank, and the heat exchange capacity of the heat exchanger built in the containment cannot be considered. For example, the patent numbers CN201611061901.7 and CN201810662023.7 all design the reinforced heat exchange structure of the novel heat exchange water tank, so that the passive containment cooling system can lead out the heat in the containment for a long time. However, it is also important to enhance the heat exchange capacity of the built-in heat exchanger itself.
Therefore, it is necessary to invent a high-efficiency heat exchanger built in a containment vessel with a gas storage compartment, and the heat exchange capacity of the heat exchanger is enhanced by collecting high-concentration air around a storage heat transfer tube and in the whole upper space of the containment vessel, so that a large amount of steam generated when a break accident occurs in the containment vessel is efficiently taken away. And the over-temperature and over-pressure inside the containment vessel are prevented, and the safe operation capacity of the nuclear power station is improved.

The invention is mainly applied to the conditions of the reactor main coolant system or the main steam pipeline under the break accident. When a break accident occurs, the containment gas space 12 is blown to generate a large amount of high-temperature and high-pressure steam, so that the temperature and the pressure of the steam are continuously increased. In the initial stage of spraying, the temperature and pressure rise generated by steam is mainly absorbed by the inner wall surface 13 of the containment, the pit and other internal components of the containment; in the later stage of spraying, the heat in the containment is mainly led out by the heat exchanger 1 arranged in the containment.
With the long-term development of accidents, a large amount of high-temperature steam flows upwards along the main flow area due to the action of initial kinetic energy and buoyancy. When the steam reaches the heat exchanger 1 in the containment, the steam and the heat transfer pipe perform condensation heat exchange process, and heat is transferred to the coolant in the pipe. But the heat exchange process between the steam and the heat exchanger is inhibited due to the presence of significant amounts of non-condensable gases in the containment gas space 12 itself.

The system comprises three parts: a water delivery structure 6 (fig. 2), a jet structure 7 (fig. 2) and a suction structure 8 (fig. 3). The non-condensable gas film around the heat exchange tube is absorbed by utilizing the kinetic energy converted from the potential energy of water flow generated after the steam is condensed, so that the thickness of the gas film on the wall surface of the heat transfer tube can be effectively reduced, the direct contact between the steam and the heat exchange tube is enhanced, and the condensation heat exchange capacity of the heat exchanger built in the containment is enhanced. Steam flushes the outer wall surface of the containment built-in heat exchanger 1 under accident conditions. The high-temperature steam and the heat transfer pipe of the built-in heat exchanger are contacted to form a condensation heat exchange process, the water temperature of the upper pipe section 4 of the heat exchanger is continuously increased, and the density is continuously reduced. And natural circulation flow is formed under the driving of the gravity difference of the upper pipe section 4 and the lower pipe section 5, so that heat in the containment can be effectively conducted out, and the overtemperature and overpressure of the containment can be prevented.

The driving shell and the driven shell are arranged on the inner wall of the containment through support columns.
When a large amount of steam is condensed on the containment built-in heat exchanger 1, a large amount of condensed water is generated, so that the condensed water flows downwards on the containment built-in heat exchanger 1 along the gravity direction, at the moment, a funnel 18 in a water conveying structure 6 collects the condensed water and continuously flows downwards through a funnel water conveying pipe 19, when the condensed water reaches a jet mechanism 7, jet flow is generated on a rotating wheel 23 due to the existence of water flow potential energy and a nozzle 21, a water bucket 24 is hit, the rotating wheel 23 rotates fast, the rotating force is transmitted to an air suction impeller 27 through a main shaft 25 and a gear steering box 26, the air suction impeller 27 rotates fast in an air suction structure 8, negative pressure is generated, suction force is formed, a non-condensable gas film near the heat exchange pipe is sucked away through an air suction pipe 9, the contact between the steam and the tube bundle is enhanced, and efficient heat transfer is realized.
The water sprayed from the nozzle 21 strikes the bucket 24 and is discharged to the pit through the drain pipe 11 for storage.
