Specific embodiment
Specific embodiment of the present utility model is described further below:
As shown in Figs 1-4, a kind of quadrangle body pine material layer filler, including support column 1, stiffening plate 2, four support columns 1 connect
It connects and is fixed on same endpoint, the angle between two neighboring support column 1 is 109.47 °, by stiffening plate between any two support column 1
2 are connected and fixed, in use, the filler is evenly arranged in the high-temperature material solid particle of gas-solid contact waste heat recycling.
Four 1 specifications of support column are identical.
The support column 1 is cylindrical body or prism.
The stiffening plate 2 is 6, and the specification of 6 stiffening plates is identical, and one is fixed between every two support column 1
Stiffening plate 2 constitutes isosceles triangle between support column 1 and stiffening plate 2.
The support column 1 and the material of stiffening plate 2 are steel, iron or ferroalloy.Support column 1 and stiffening plate 2 have good
Thermal conductance and thermal stability.
Support column 1 and stiffening plate 2 can be made up of an overall processing of the methods of grinding tool shearing, casting, can also be with
Production (is such as welded, cuts) by other methods.
A kind of application method of quadrangle body pine material layer filler, by quadrangle body pine material layer filler according to high-temperature particle object
The ratio uniform that material mass ratio is 0.2~5 is blended in the high-temperature particle bed of material, and quadrangle body pine material layer filler is to granule materials
It plays a supporting role, promotes the distance between high-temperature particle or between particle swarm to increase, to improve the voidage of the bed of material；
Little particle and powdery high-temperature material focus between support column 1 and stiffening plate 2, corresponding to reduce bulky grain high temperature substrate
The accumulating amount of granular material between material increases the gap between bulky grain high temperature granular material, to increase the height of bulky grain
The mobility of air-flow between the warm particle bed of material；
The little particle and powdery high-temperature material and quadrangle body pine material layer filler being deposited between support column 1 and stiffening plate 2
Between sufficiently it is thermally conductive, increase the heat exchange efficiency of quadrangle body pine material layer filler.
It can adjust Bed Void by the mixed proportion of change quadrangle body pine material layer filler and high-temperature particle and become
Change.
See Fig. 3, usual particle bed of material gap 4 is smaller, and the gas of phase homogenous quantities is larger by unit section materialbeds comminution.See
Fig. 4, after the high-temperature particle bed of material 3 is uniformly added into quadrangle body pine material layer filler, because filling-material structure supporting role makes the particle bed of material
Gap 4 increase, air-flow can it is smooth by gap 6 around the body pine material layer filler of quadrangle and quadrangle body pine material layer filler inside
Space, so that the gas circulating resistance of the unit bed of material be effectively reduced.Meanwhile lesser particle can enter quadrangle body pine material layer
Inside filler, to increase intergranular space 4, and bed of material porosity profile is more uniform.In application shaft furnace to quadrangle body pine
When the mixed material of material layer filler and hot particle bed of material composition carries out waste heat recycling, quadrangle body structure is not easy at the top of shaft furnace
Bed of material section voidage is uneven caused by assembling in cloth process there is a situation where rolling, therefore the more uniform height of cooling procedure
Effect.
The addition of quadrangle body pine material layer filler increases 3 gas-solid heat exchange areas of the high-temperature particle bed of material, and quadrangle body material
There is layer filler good heat conductivity, the high-temperature particle bed of material 3 and quadrangle body pine material layer filler to pass through the heat transfer between solid
Heat transfer is carried out with modes such as heat radiations, therefore mixture interlayer gas-solid heat exchange efficiency will increase.Quadrangle body pine material
The structural strength of layer filler is functional, and it can be used repeatedly.
The mixed proportion of quadrangle body pine material layer filler and the high-temperature particle bed of material 3 can run the specific feelings of operation according to shaft furnace
