Specific embodiment
Cold with separate air to a kind of outside of the present invention with specific embodiment below in conjunction with the accompanying drawings
But the containment of hot trap is further described.
As shown in figure 1, a kind of outside of the present invention carries the containment that separate air cools down hot trap,
Wherein include pressure vessel 2 and primary Ioops pressure boundary 7 etc. in containment 1.Containment in the present invention
1 can adopt prestressed concrete containment vessel, it would however also be possible to employ steel containment vessel.
It is welded and fixed many evaporation ends heat pipes 4 around containment 1 outer wall, these evaporation ends heat pipe 4 quilts
It is divided into some groups；The top exit connection of every group of evaporation ends heat pipe rises the entrance of connecting tube 5 on the way, should
The outlet of road rising connecting tube 5 includes the top of one group of condensation end heat pipe of many condensation end heat pipes 6
Entrance, the outlet at bottom of this group condensation end heat pipe connects the entrance of connecting tube 10 on the way down, and this road declines
The bottom inlet of one group of evaporation ends heat pipe of outlet of connecting tube 10.The height of every group of condensation end heat pipe is equal
Height higher than every group of evaporation ends heat pipe.
Every group of condensation end heat pipe is arranged in the bottom of a chimney 3, and chimney 3 is supported by bracing frame
On the ground, air from the bottom of chimney 3 freely through chimney.Chimney 3 effect is to strengthen nature
Heat convection.Described chimney is also called air cooling tower.
Working media flows through evaporation ends heat pipe 4 successively, rises connecting tube 5, condensation end heat pipe 6 and decline even
Adapter 10, returns again to evaporation ends heat pipe 4, and forming closure waste heat derives loop.Working media is water, first
Alcohol, ethanol, acetone or ammonia.
It is respectively provided with evacuation quick access device 8 and vacuum monitoring system 9 on rising connecting tube 5.Take out true
Empty quick access device 8 is quick coupling device, at ordinary times for self sealss state, can be quickly external true during use
Empty pump is carrying out vacuum pumping.Vacuum monitoring system 9 can be with the vacuum in on-line monitoring pipeline, such as
Truly reciprocal of duty cycle reduces, and produces on-condensible gas, just extracted in pipeline by evacuation quick access device 8 in pipeline
Incondensable gas, to maintain the cooling capacity of system.
The quantity of 4 or many condensation end heat pipes 6 of above-mentioned many evaporation ends heat pipes can at 500～50000,
Waste heat with specific reference to reactor core determines, make waste heat that the reactor core that many evaporation ends heat pipes 4 carry produces with many
Root condensation end heat pipe 6 heat that air cooling carries in chimney is equal, meets the requirement of Core cooling.
The entrance of all condensation end heat pipes 6 that above-mentioned every group of condensation end heat pipe includes can collect in same company
Connect in case, the entrance connection of this connecting box rises the outlet of connecting tube 5 on the way；This group condensation end heat pipe bag
The outlet of all condensation end heat pipes 6 including can collect in same connecting box 11, this connecting box 11
The entrance of outlet connecting tube on the way down 10.
The outlet of all evapn end heat pipe 4 that every group of above-mentioned evaporation ends heat pipe includes can collect in same
In connecting box, the outlet of this connecting box rises the entrance of connecting tube 5 on the way；This group evaporation ends heat pipe
Including the entrance of all evapn end heat pipe 4 can collect in same connecting box, the entrance of this connecting box
Connect the outlet of connecting tube 10 on the way down.
A kind of outside of the present invention carries the containment operation principle that separate air cools down hot trap：When
It is possible to primary Ioops pressure boundary 7 ruptures when nuclear power station has an accident, in pressure vessel 2, send out
Raw reactor core melts, and produces substantial amounts of hydrogen, and the gas full of high temperature in containment 1, if not by heat
Persistently take away, containment 1 will superpressure, occur rupture lead to radioactivity to discharge in a large number.In containment 1
Heat by heat being passed by way of radiation and containment 1 heat conduction in convection current in shell, steam condensation, shell
Pass evaporation ends heat pipe 4, the working media evaporation in evaporation ends heat pipe 4, by way of the latent heat of vaporization
Heat in containment 1 is taken away, passes through after working media evaporation to rise even by way of Natural Circulation
Condensation end heat pipe 6 is transferred in adapter 5, by the wind scorpion of pulling out of chimney 3, strengthens the heat convection of air,
Condensation end heat pipe 6 is cooled down, the heat in containment 1 is discharged by final realization with air hot trap.
The present invention is not strictly limited to described example.According to analog structure proposed by the present invention, permissible
It is applied to any kind of nuclear reactor.
