Deflector 12, assignment of traffic disk 13.
Connection method is:Bottom plate 5 is seated on ground;Metal containment 1 is seated on bottom plate 5, and the two passes through metal containment
Bottom (head) 16 is connected;Containment internal structure 3 is located in metal containment 1;Outer panel 4 is seated on bottom plate 5, and the two passes through joint bar
It is connected;Top cooling water tank 7 is seated on top plate 6;Top cooling water 8 is stored in top cooling water tank 7;Lateral cooling water 2
It is stored in the lateral water tank 11 of metal containment;Lower air inlet 9 and upper discharge hole 10 are located on outer panel 4.
The metal containment 1, is made up of metal containment main body 14, cover head 15, bottom (head) 16.
The metal containment main body 14, is made up of ring and vertical tile water tank 11.
The water tank 11, is separated between ring is uniformly distributed along metal containment ring using dividing plate 17.Vertically it is being divided into
Into multilayer, separated up and down by steel frame 23 and dividing plate 17 between every layer.Radiator material carries out anti-corrosion treatment, to prevent rust
Erosion.The vapor generated under vertically by pipeline 18 upwards export accident conditions, and it is used as the stream of the downward spilling water of upper strata water tank
Road.
The cover head 15, by cover head dividing plate 20, water storage board 21, cover head top plate 22 are constituted.
The outer panel 4, its internal diameter is bigger than the diameter of metal containment 1, between leave enough operating spaces.
The top cooling water tank 7, is supported on top plate 6, there is the reinforced concrete structure of stainless steel clad can using inner side.
The pipeline 18, at the middle part of each water tank, consistency from top to bottom.Using materials such as stainless steel round steel pipe or PVC, its
Top should about 10cm lower than tank top.
The bottom steel frame 23, in the bottom of every layer of water tank, the steel construction for the cantilever being supported on water tank madial wall 14
Framework.Weight for undertaking upper tank and its middle water.
The spout hole 24, in the discharge casing upper outside position perforate of the bottom one, perforate is along ring, long arc shape hole.
When bottom cistern water level reaches position of opening, start draining.
The discharge outlet 25, in every layer of water tank bottom, is connected with water tank, with opening and closing device.Emptying is needed for maintenance etc.
Water in water tank.
When the present embodiment is performed, the reinforcing bar and template of bottom plate 5 are first arranged, by the bottom (head) 16 of metal containment 1 and bottom plate 5
Reinforcing bar is firmly connected, subsequent bottom board concrete.Afterwards again by the annexation of each part in the present invention, layering is progressively built
Make.
After the completion of the present invention is built, cooling water is injected in top cooling water tank 8 and the lateral water tank 11 of metal containment.
Under accident conditions, water in the cooling water tank of top enters at the top of containment, is flowed then along cover head to surrounding, into lateral
Water tank.Water in simultaneously lateral vertical is also cooled down to containment main part, and water is evaporated, evaporation and sky by water
Flow of air is by Residual heat removal, it is ensured that the security of whole nuclear power station.Even if top cooling water tank goes wrong and can not sprayed cold
But water, relying only on the automatic evaporation of lateral cooling water can also largely play a part of discharging waste heat.
When of the invention specifically used:
After the completion of being built by the foregoing order of connection, to one layer of annular water tank and top cooling water of containment main body topmost
Case water filling, after lateral the superiors' water tank is full, from water tank intermediate conduit to lower floor's successively water filling.Under accident conditions, top cooling
Cistern valve is opened, and top cooling water is evenly distributed on metal containment cover head by assignment of traffic disk, and cover head is carried out
Cooling, meanwhile, lateral water tank also begins to evaporation, generates vapor.The vapor of lateral water tank will pass through middle unicom pipeline
Discharged to top.Under air baffle guiding, cold air is introduced from bottom, takes away vapor, and vapor is from upper discharge hole
Space discharge between the cooling water tank of top, and take away waste heat.The unevaporated water of cover head flows to lateral water tank simultaneously, to lateral
Water tank carries out moisturizing, and upside Water in Water Tank is expired, and by intermediate conduit, gravity flow enters next water tank, successively fed.Orlop water tank
Lateral openings are left, superfluous water is laterally overflowed by orlop.By the intrinsic physical characteristic of water and air, the present invention can be quick
The waste heat generated under accident conditions is discharged into air, so as to reduce the probability of the serious accidents such as fusible core generation.Simultaneously in water tank
Bottom sets lateral drinking-water pipe, convenient maintenance draining.
