Description
Technical field
It the utility model is related to a kind of coal water slurry gasification furnace structure, and in particular to a kind of slag of coal water slurry gasification furnace zone water cooling
Mouth brick structure.
Background technology
Texaco Water-coal-mud Gasification Technology and four nozzle coal water slurry gasification technologies are added by feeding manner of water-coal-slurry
Calm the anger fluidized bed gasification process；Texaco gasifier and four nozzle gasification furnaces are the critical equipments for realizing gasification process；Gasification furnace master
To include arch crown part, stack shell position, bore bottom and cinder notch position；Wherein slag notch brick is that slag stream and airflow scouring are most tight in gasification furnace
The place of weight.The lower section of slag notch brick is brick plate, and brick plate plays a part of supporting slag notch brick, and the lower section of brick plate is Quench
Ring, chilling ring injection water carry out Quench；1 in cinder notch brick structure such as Fig. 1 is lower floor's brick, builds the brick on brick plate by laying bricks or stones；During 2 are
Between brick, build by laying bricks or stones on the brick of upper strata, middle transitional brick；3 be upper strata brick, is that head works as it when going out in burner hearth under the gentle flow direction of slag stream
Brick of the punching by erosion；4 be brick plate；The lower section of brick plate is that chilling ring 5,6 is down-comer；Three layers of refractory brick are from top to bottom
Form three rank dripping eaves；Purpose is slag is fallen directly into down-comer, avoids slag along brick wall and lower erosion brick
Wall, ablation brick plate and chilling ring.
But later stage, the slag of high temperature drop down brick plate and Quench along three rank dripping eaves of slag notch brick in actual use
On ring, when these slag notch bricks do not have the effect of protection brick plate and chilling ring it is necessary to changing slag notch brick.Can gasification furnace be grown
Cycle stability run with whether blowing out to change brick relevant, change brick and brick plate and chilling ring can be effectively protected it is relevant.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of cinder notch of coal water slurry gasification furnace zone water cooling
Brick structure.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of cinder notch brick structure of coal water slurry gasification furnace zone water cooling, described cinder notch brick structure include brick plate, built by laying bricks or stones
Lower floor's brick, middle brick and upper strata brick, the chilling ring and down-comer that are fixed on brick plate bottom on brick plate；The support brick
Plate, chilling ring internal face on be fixed with hexsteel；The lower end of the hexsteel is concordant with the delivery port of chilling ring；Described tortoise
First net and the brick plate, chilling ring internal face between, between the lower surface of brick plate and chilling ring be filled with heat-conducting layer.
The utility model proposes a kind of coal water slurry gasification furnace zone water cooling cinder notch brick structure, utilize using chilling ring water
It is cold so that along cinder notch and under cinder formation one layer of slag blanket protection is condensed on the hexsteel of brick plate and chilling ring outer layer
Layer, adequately protected brick plate and chilling ring, extends the service life of brick plate and chilling ring, is advantageous to the long week of gasification furnace
Phase stable operation.
Brief description of the drawings
Fig. 1 is coal slurry gasifier cinder notch brick structure in the prior art.
Fig. 2 is structural representation of the present utility model.
In figure：1st, lower floor's brick, 2, middle brick, 3, upper strata brick, 4, brick plate, 5, chilling ring, 6, down-comer, 7, hexsteel,
8th, high thermosphere.
Embodiment
The utility model is illustrated with reference to the drawings and specific embodiments：
As shown in Fig. 2 a kind of cinder notch brick structure of coal water slurry gasification furnace zone water cooling, described cinder notch brick structure includes support
Brick plate 4, the lower floor's brick 1 built by laying bricks or stones on brick plate, middle brick 2 and upper strata brick 3, the chilling ring 5 for being fixed on brick plate bottom and under
Pipe 6 drops；The brick plate 4, chilling ring 5 internal face on be fixed with hexsteel 7；Described hexsteel is by 10mm thickness
1Cr18Ni9Ti is made；The lower end of the hexsteel 7 is concordant with the delivery port of chilling ring 5；Described hexsteel 7 and the support brick
Between plate 4, the internal face of chilling ring 5, the lower surface of brick plate and chilling ring between be filled with heat-conducting layer 8；In the embodiment
Described heat-conducting layer 8 is carborundum ramming mass, and the thickness of carborundum ramming mass is 20mm.
Before laying bricks, the center line of cinder notch position is first looked for, on the basis of longitudinal center line, according to diameter as defined in each ring brick
Accurately build lower floor's brick, middle brick and upper strata brick by laying bricks or stones.Then in the outside of brick plate and lower section filling carborundum ramming mass.Build by laying bricks or stones
Cheng Hou, it can be heated up without baker, feed intake operation.The technical solution of the utility model is mainly by brick plate and Quench
Ring external welding hexsteel, the good carbofrax material of thermal conductivity factor is filled to realize：Hexsteel is from high temperature resistant 1Cr18Ni9Ti's
The thickness of hexsteel is 10mm on the outside of material, brick plate and chilling ring, and the lower end of hexsteel exceeds 3/4 position of chilling ring；Tortoise
The carborundum ramming mass of filling high heat conduction in first net, the thickness of carbofrax material ramming is 20mm.
