This up adds every certain altitude and sets a furnace wall support ring；An annular ex-pansion is arranged in the lower section of support ring in furnace wall
Seam, seam is interior to be filled up with refractory fibre；On cyclone separator top, vertical array is provided with refractory metal pull rod, one end connection
At the top of steel shell；The other end is placed in the hanging hole of corresponding headliner suspended block.
A kind of high temperature cyclone separator of the utility model combines furnace wall, and furnace wall support ring is supported by more than two furnace walls
Block is arranged in a combination along outer steel shell periphery；Furnace wall supporting block is combined by refractory metal support and inner liner support brick and filler material
It forms.One end of metal support connects steel shell, and the other end is placed in the bracket of inner liner support brick inboard；
The utility model has the beneficial effects that high temperature cyclone separator liner tile selects the elevated temperature strengths such as silicon carbide big, resistance to
Grind that performance is good and the seam allowance combination brick masonry of resistance to rapid heat cycle.Although its thickness is no more than a quarter of furnace wall, it wears
Service life at least 10 years or more；Four sides seam allowance cooperates, and a strong working face is formd on the outside of furnace wall；In strong work
Make behind face with density very little, the filling of the materials such as the good light-weight insulating brick of heat insulating ability, insulation fibre blanket.Make to combine furnace wall quality
It is gently only very 50% or so, external skin temperatures reduction by 40% or more fine with heat-proof quality of stack pile castable furnace wall.From cone cylinder
Lower mouth starts, and installs the furnace wall support ring made of being spliced and combined as more than two furnace wall supporting blocks along garden week；Thus up,
It is added every certain altitude and sets a furnace wall support ring；The lower section of support ring in furnace wall is arranged an annular ex-pansion seam, stitches interior use
Refractory fibre fills up.Multiple furnace wall support rings and annular ex-pansion, which are stitched, is divided into multiple trifles for entire furnace wall.Dilatation joint absorbs under it
The thermal expansion of Fang little Jie, the furnace wall weight of support ring support top trifle.Entering magnetic combination keeps protecting wall structure sufficiently stable.Top furnace
The structure that wall is matched with the suspended block with hanging hole with metal pull bar is hung in liner tile at the top of cyclone separator on steel shell；It hangs
It is all filled with light thermal-insulation fibrous material between brick and top shell.

Specific embodiment
As shown in Fig. 1 Fig. 2 figure .3 Fig. 4, a kind of high temperature cyclone separator combination furnace wall serves as a contrast one on the inside of steel casing 1
Layer liner tile 2 made of silicon carbide or alumina material；Gap 3 is equipped between steel shell 1 and liner tile 2；It is used in gap 3
Lightweight refracrory 4 is filled；The mouth under cyclone separator cone cylinder 5 is provided with one by more than two 15 edges of furnace wall supporting block
Furnace wall support ring 11 made of garden week splices and combines；Thus up, added every certain altitude and set a furnace wall support ring；In furnace
The lower section of wall support ring 11 is arranged an annular ex-pansion seam 14, is filled up in seam with refractory fibre；On cyclone separator top 8, vertically
It is disposed with refractory metal pull rod 9, one end is connected to the top of steel shell 1；The other end is placed in corresponding headliner
In the hanging hole 10 of suspended block 12.
A kind of high temperature cyclone separator of the utility model combines furnace wall, and furnace wall support ring 11 is supported by more than two furnace walls
Block 15 is arranged in a combination along outer steel shell periphery；Furnace wall supporting block 15 is by refractory metal support 6 and inner liner support brick 13 and fills out
Charge is composed.One end of metal support 6 connects steel shell 1, and the other end is placed in the inboard bracket 7 of inner liner support brick 13；
2 optimal selection of liner tile of the utility model is the seam allowance modular tile for having concave-convex seam allowance on side；
The utility model liner supports at least one bracket 7 of inside, that is, non-working side of brick 13；
More than two hanging holes 10 are preferably formed on the utility model headliner suspended block 12；
It is preferably all filled with refractory fibrous material in gap at the top of the utility model between suspended block 12 and top steel shell.
The utility model high temperature cyclone separator furnace wall, the seam allowances such as working face silicon carbide or corundum combine brick masonry.
High temperature abrasion resistance is good, and intensity is big, and stability is good；The filler materials such as light-weight insulating brick and insulation fibre are used between liner tile and steel shell
It tamps, is allowed to form an entirety with silicon carbide or corundum liner tile and steel shell.Because liner tile only accounts for the 20% of furnace wall thickness
Left and right, but its elevated temperature strength is big, and wear-resisting property is good, non-maintaining enough to use 10 years or more；Remaining 80% is entirely thermally conductive system
The very low lightweight refracrory of number, so, furnace wall integral heat insulation performance is fine, very light in weight, thermal capacity very little！The mouth under cone cylinder
Start, is combined into furnace wall support together with support liner tile with Support bracket is fabricated to by refractory metal material such as stainless steel etc.
Splice and combine into a complete furnace wall support ring garden Kuai Yan week.Every a Duan Gaodu, a furnace wall support ring is added；In furnace wall
One dilatation joint is set below support ring, which only absorbs the expansion of this section of furnace wall below, the furnace in dilatation joint branch
Wall support ring only supports the weight of its one section furnace wall of top.Entire furnace wall is divided into multiple stress and the relatively independent furnace wall of gravity
Trifle.So combination keeps protecting wall structure sufficiently stable.The composite structure of top furnace wall stainless reinforcing pull rod and liner suspended block, every piece
Multiple hanging holes are provided on suspended block, it is ensured that the structure safety of furred ceiling.Gap above furred ceiling is all filled out with fire resistant heat preserving fiber
It fills, weight is lighter, and thermal insulation property is more preferable.
