Background technology
In sodium-cooled fast reactor; the temperature of liquid metal sodium is higher in the reactor vessel; can be above 500 ℃; in order to reduce thermal loss; reduce the temperature difference and the thermal stress of reactor vessel; the concrete of the heap of protective reaction simultaneously reactor pit, and the heat-insulation layer that present existing pressure vessel or corresponding pipeline use all can not satisfy the requirement of sodium-cooled fast reactor, have in addition can't use.
Summary of the invention
The utility model has overcome deficiency of the prior art, and the metallic insulation that is used for the sodium-cooled fast reactor container of a kind of high temperature resistant, anti-irradiation, antidetonation, simple in structure, easy to assemble, high insulating effect is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of metallic insulation that is used for the sodium-cooled fast reactor container, it is made up of the splicing of a plurality of heat insulating blocks, heat insulating block be make by stainless sheet steel box-like, interior dress multilayer stainless steel foil; Wherein inside and outside two side cover plates of heat insulating block are the mirror face stainless steel plate, and stainless steel foil is a corrugated, and every adjacent two layers ripple is staggered into 90 °.
The utility model is all right: described heat insulating block is stepped, overlap joint installation mutually between the heat insulating block, and the slit adopts stainless sheet steel to cover.Heat insulating block is made box-like frame by stainless sheet steel, and on framework, inner cover plate is riveted on the framework outer cover plate by resistance spot welding.Heat insulating block is fixed on the container outer wall by bolt, nut, bolt sleeve, clamping pad.Described heat insulating block is provided with 2～4 bolt sleeves, and bolt is connected on the base of chamber wall, and can be free movable in base.Described nut is a sphere, and the clamping pad through hole is the conical surface.
Compared with prior art, the beneficial effects of the utility model are:
Because heap container profile is huge, heat-insulation layer is designed to the splicing of polylith heat insulating block to be formed, and each heat insulating block can be fixing separately on container, and the heat insulating block shape can design according to the zone of its place container, greatly facilitates the dismounting of heat-insulation layer.And inside and outside two side cover plates of heat insulating block adopt the mirror face stainless steel cover plate, innerly adopt undulatory stainless steel foil alternative arrangement, well like this heat are isolated the greatly radiation loss of the minimizing reactor vessel of degree.In order better to avoid circulation of air, heat insulating block is designed to stepped, and overlap joint is installed between the heat insulating block, and the stainless steel cover plate is housed on the seam, makes better heat preservation.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
The metallic insulation scheme of installation of sodium-cooled fast reactor container as shown in Figure 1, insulation layer thickness calculates decision by the thermal technology.Heat-insulation layer is divided into conical head heat-insulation layer 1, takes over parts such as heat-insulation layer 2, cylindrical shell heat-insulation layer 3, ellipse head heat-insulation layer 4 according to position and shape, and the gap is even between heat-insulation layer and the chamber wall.
Heat-insulation layer is made up of a plurality of heat insulating block splicings, and wherein the size of heat insulating block can easily be carried with a people and is advisable.Heat insulating block is a box like structure, and wherein the profile of box is made according to the container appearance curved surface at position, place, as shown in Figure 2.The framework 11 usefulness stainless sheet steels of box are made, and inside and outside two side cover plates 14,15 are used the mirror face stainless steel plate, and on framework 11, inner cover plate 15 is housed to stainless steel foil 10 backs and uses rivet 13 to be riveted on the framework 11 outer cover plate 14 by resistance spot welding.Cassette interior is the bright mirror surface reflection type structure that multilayer stainless steel foil 10 is formed.Stainless steel foil 10 adopts the cold-press moulding technologies that stainless steel foil 10 is pressed into corrugated, as shown in Figure 3, behind stainless steel foil 10 press formings, cuts according to the size of cassette frame 11, guarantees that edge and framework 11 inner edges coupling are well.And in the framework 11 of packing into one by one after the cleaning, adjacent two layers stainless steel foil 10 coincides and should make ripple be staggered into 90 °, and the connection between the stainless steel foil 10 adopts series spot welding or seam weldering to connect, and welding joint should stagger up and down.The number of plies of required stainless steel foil 10 is determined according to box thickness.
In order better to avoid circulation of air, make better heat preservation, the box of heat insulating block is made stepped, overlap joint is installed, and the slit covers with stainless sheet steel 12, and stainless sheet steel 12 spot welding are therein on one of heat insulating block, when heat is swollen, can move freely each other, as shown in Figure 4.
Heat insulating block is by bolt 5, nut 6, bolt sleeve 8, clamping pad 7 is fixed on the heap container, structure as shown in Figure 5,2～4 bolt sleeves 8 are set on each heat insulating block, during installation the position of good bolt 5 on chamber wall determined in heat insulating block splicing back, bolt 5 is to fix by the base 9 that is welded on the chamber wall, it can be free movable in base 9, between nut 6 and the clamping pad 7 sphere and conical surface combination, therefore the orientation of bolt 5 can be adjusted, with the bolt sleeve 8 that adapts to heat insulating block can not fine centering bolt 5 situation, the snap-in force that is threaded is born by bolt sleeve 8.
Metallic insulation mainly utilizes stainless steel foil 10 and its good reflecting heat performance to be incubated, the metal heat preservation layer material should be smoothly light, do not have obvious scratch, do not have the defectives such as harmful crackle, scar, dirt and corrosion that influence usability, stainless steel foil 10 must have bigger reflectivity.
The heat that when this device can be used for reactor vessel and normally moves its high temperature outside surface is reflected is isolated; its heat-blocking action; reduce radiation loss; thereby the heat that reactor is produced is used for generating electricity effectively; reduce heap chamber wall internal-external temperature difference, reduce thermal stress, concrete shield of the heap reactor pit of protective reaction simultaneously; avoid overheated and cause that ability to work reduces, cause damaging.
