Description
Technical field
The utility model belongs to device for producing hydrogen component technology field, particularly relates to a kind of device for producing hydrogen flue front arch.
Background technology
As everyone knows, hydrogen manufacturing conversion furnace fire box temperature is at about 1000 DEG C, and traditional rectangular flue front arch at this temperature, often occur fracture, and this fracture all occurs in the centre position of flue front arch.In addition, existing flue front arch is solid en-block construction, and size is comparatively large, and sintering process is not easy to grill thoroughly, and bursts situation and often occur under also causing applied at elevated temperature environment; Moreover reburner maintenance process, flue cover plate turns top normally operation side, is also easy to cause its fracture damage, thus affects the uniformity of fire box temperature field and the performance of reburner.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of structure simple, and easy to implement, intensity is high, long service life, good seal performance, ensures the device for producing hydrogen flue front arch of reburner good heat transfer capacity.
For solving the problems of the technologies described above, the technical solution of the utility model is:
Design a kind of device for producing hydrogen flue front arch, comprise brick body, these brick body two sides are opposing parallel inclined-plane, and wherein a side first half is outwards provided with boss, the corresponding first half of opposite side is inwardly provided with groove, and this boss mates with groove shapes size, to be fastened connection for adjacent two pieces of bricks, described brick body is hollow structure, and parallel longitudinally bottom brick body is provided with multiple raised line or groove.
Further, described hollow structure is the vertical oval hole of parallel longitudinal setting.
Preferably, the edges and corners of described boss and/groove are arc transition structure.
Preferably, described brick body adopts mullite flame-proof castable moulding by casting, and dispersion is provided with many steel fibres in brick body.
The beneficial effect of technical solutions of the utility model is:
1, structurally, both sides are set to parallel-slope to the utility model device for producing hydrogen flue front arch and correspondence is provided with the boss and groove that match, during use, adjacent two pieces of lap buckles are combined, anatomical connectivity is firm, in horizontal plane, in left and right directions or vertical plane, above-below direction is not easy to slide, substantially increase overall structure sealing, effectively prevent from altering outside flue gas, make flue front arch both sides flue gas even, improve front arch flue gas environment, improve flue gas utilization rate, fully ensure that reburner has good heat transfer property.
2, structurally, splicing form between brick and brick is changed into left and right overlap joint and fastens type of attachment by the utility model, make thus front arch by single stressed be changed to overall stressed, flue is finally made to form entirety, thus the overall compressive strength of flue is reduced when reburner repair and maintenance, improve the overall break resistance of flue; In addition, brick body is designed to hollow structure, relative to existing solid construction, easily grills thoroughly, and can obtain comparatively macrostructure intensity, and weight reduction simultaneously, reduces costs, can also conveniently install and transport.
3, structurally, the utility model sets up raised line or groove bottom brick body, can strengthen the resistance to compression of brick body, shearing resistance and bending and tensile strength, extends the service life of the even whole flue of brick body; Hollow-core construction is designed to vertical oval hole, more can strengthen the resistance to compression of brick body, shearing resistance and bending and tensile strength relative to horizontally disposed oval hole; Set up arc transition structure in the edges and corners of boss and/groove, reduce stress and concentrate, improve brick body break resistance; Brick body adopts heater wire to change little mullite flame-proof castable moulding by casting, and disperses uniformly to add many steel fibres when pouring into a mould, and makes it be not easy fracture, even if there is the extension that fracture also can slow down crackle, and the generation of Chimney cover plank split during to reduce work.
4, to sum up, the utility model device for producing hydrogen flue cover plate brick structure is simple, easy to implement, can improve flue overall structure sealing, improves flue gas utilization rate, fully ensures that reburner has good heat transfer property; And the resistance to compression of brick body, shearing resistance and bending and tensile strength can be strengthened, improve the overall break resistance of flue, thus extend the service life of brick body and whole flue, therefore, be very suitable for promotion and implementation.
