Description
Technical field
The utility model relates to a kind of combined water coal slurry gasification stove furnace roof nozzle brick.
Background technology
Coal slurry gasifier new stove needs its baker when driving, and puts into preheating burner and heats, until extract after feed temperature, then nozzle brick is filled in fire door from top fire door, and feed intake after closing operation.When vapourizing furnace normally runs, nozzle brick is the same with key brick, and a slag-resistant is washed away, slag-resistant erosion action; When vapourizing furnace needs blowing out inspection or maintenance, fire door nozzle brick will be pulled out, so that pre-heat drying furnace again after maintenance, continue start-of-run, Reusability like this.
Existing coal slurry gasifier furnace roof nozzle brick all adopts method global formation that is prefabricated or that build, time shaping, heat-resisting reinforcing bar is inlayed in inside, then light-burnedly below 1000 DEG C to form, intensity is low, volume is unstable, is not drawn out easily, easily ruptures during shutdown maintenance, can only single use, waste resource; And break off remnant part must be destroyed with pneumatic pick, the key brick of also easily damage contact around, reduces vapourizing furnace whole service life.
Utility model content
The purpose of this utility model is to design a kind of combined water coal slurry gasification stove furnace roof nozzle brick, abandon prefabricated or poured integral forming method, break away from forming method constraint, by a plug mouth brick along the symmetrical dimidiation of reducing right cylinder concentric reducer central cross-section, A-A cross section adopts hydraulic vibration shaping upward respectively; Burnt till until reach 90 high-chrome brick sintering degree by high-temperature shuttle kiln high temperature; Place heat-resisting reinforcing bar (800 DEG C) grid in the middle of two hemihedry plug mouth bricks after burning till, and stretch out the external formation handle of brick, to extract during blowing out.The advantages such as the utility model has that compressive strength is high, volume density is large, chromium content is high, erosion-resisting characteristics good, easy to operate, with prefabricated with build the nozzle brick single use life-span and compare, can realize using 2-3 time continuously, economize on resources, reduce costs.
As shown in Figure 1, the utility model is by two pieces of symmetrical brick bodies (1), inner high temperature steel reinforced net (2), outside heat-resisting stirrup (3) and Thermal Resistant Surface fibrous paper (4) four part composition, wherein the shape of symmetrical brick body is the conical section shown in Fig. 2 and the combination of the bottom round platform section linked into an integrated entity, the shape of inner high temperature steel reinforced net (2) is Fig. 3, shown in 4, it inlays the interior high temperature steel reinforced net hole (5) in insertion two pieces symmetrical brick body (1) section, two pieces of symmetrical brick bodies (1) are connected in interior high temperature steel reinforced net groove (6), the outside two ends up and down of symmetrical brick body (1) reserved groove (7) respectively, the degree of depth of groove (7) is more than or equal to the thickness of outside heat-resisting stirrup (3), outside heat-resisting stirrup (3) shape is Fig. 5, after two pieces of symmetrical brick bodies (1) directly contact and merge into a single whole, snap in after groove (7) is locked by upper and lower two the heat-resisting stirrup in outsides (3), thick refractory fiber paper (4) is pasted at its outside surface, its thickness is 2-3mm, be pasted onto nozzle brick conical section and bottom round platform section outside.
Described inner high temperature steel reinforced net (2) is can resistance to more than 800 DEG C Temperature Steels, sectional view as shown in Figure 3, in approximate " well " shape, top is circular shape sealing, and after two pieces of symmetrical brick bodies (1) merge, be exposed at the external formation of brick " handle ", in process easy to use, extract nozzle brick; Left view as shown in Figure 4, is " scholar " shape.The object of such design is in order in the process of extracting nozzle brick, will act on pull transfer on " handle " to brick body, and disperse stressed, avoid extracting high temperature steel reinforced net (2), be convenient to extract nozzle brick.
The heat-resisting stirrup in described outside (3) is can resistance to more than 800 DEG C temperature steel bars, is processed into circle.Each nozzle brick outside arranges two the heat-resisting stirrup in outsides (3), each one of upper and lower, diameter is determined according to brick body size, and Main Function is by two pieces of symmetrical brick body (1) bandings, formed overall, prevent from occurring relative displacement between them.

Embodiment:
As shown in Figure 1, 2, design the technical recipe of two pieces of symmetrical brick bodies (1), shaping through batch mixing, hydraulic vibration, dry, operation obtained two pieces of symmetrical brick bodies (1) respectively such as shuttle kiln high temperature burns till.Ground finish is carried out to the forming pressing-surface of two pieces of symmetrical brick bodies (1), polishes to flat smooth, until two pieces of symmetrical brick bodies (1) merge rear contact surface do not occur gap.
Inside high temperature steel reinforced net (2) processed is inserted in symmetrical brick body (1) inner high temperature steel reinforced net hole (5), inner high temperature steel reinforced net groove (6), again symmetrical for another block brick body is aimed at high temperature steel reinforced net (2) and merge insertion, until two pieces of symmetrical brick bodies are fitted completely.By groove (7) size reserved according to brick external body for heat-resisting steel bar, curve a circle, integrally welded after banding, form outside heat-resisting stirrup (3), each one of top and bottom, diameter is determined according to brick body size.Finally paste the thick refractory fiber paper (4) of 2mm at nozzle brick conical section and bottom round platform section external portion.
This utility model product has that access times are many, intensity is high, extracts conveniently, do not stick together the advantages such as sintering, can be widely used as coal slurry gasifier and similar type of furnace furnace roof nozzle brick.
Above specific embodiment at home certain large-scale coal slurry gasifier uses, the position contacted with work atmosphere bottom nozzle brick does not reach erosion limitation, on average can reach and extract 4 times and do not rupture, do not stick together sintering yet, and work-ing life is prefabricated or builds nozzle brick 4 times.
