Description
Technical Field
The invention relates to the technical field of heat recovery coke ovens, in particular to a stable and easily constructed heat recovery coke oven vault structure.
Background
Current heat recovery coke ovens are generally comprised of a hearth, multiple flues, main walls, a coking chamber, and a roof. The coking process of the heat recovery coke oven comprises direct heating and indirect heating, coal materials are pyrolyzed in a coking chamber to generate combustible gas, part of the combustible gas is mixed with air entering from the top of the coking chamber and then is combusted, the coal materials are directly heated, and the residual combustible gas which is not fully combusted enters a descending channel in a main wall through holes in the upper part of the main wall, flows from top to bottom, flows out of the descending channel through holes in the lower part of the main wall and flows into a multi-connected flame path in the lower part of the coal materials. In the multi-connected flame path, combustible gas and air entering from the sealing wall are mixed and then fully combusted, heat is transferred to coal materials through the bottom of the carbonization chamber, combusted waste gas enters an ascending channel in the main wall through a hole in the lower part of the main wall, and finally flows out of the heat recovery coke oven body and enters a flue gas pipeline through an ascending pipe in the top of the coke oven.
The top of the carbonization chamber is of a large-span arch structure, the arch foot bricks are positioned on the upper part of the main wall, and the gravity of the arch head bricks and the refractory materials on the upper part of the arch crown is converted into horizontal lateral thrust and vertical downward pressure at the arch foot bricks. When the vault of the heat recovery coke oven with one hole is built, if the vault bricks slide and shift unstably, the vault bricks collapse, and the elevation of the vault is difficult to control, so that the traditional heat recovery coke oven building method is that all the carbonization chambers of a group of coke ovens simultaneously build the vault bricks, thus the gravity components (horizontal lateral thrust) borne by the vault bricks of the adjacent carbonization chambers can be mutually offset, and the stability of the vault bricks is ensured, but a group of coke ovens usually consists of 10-20 carbonization chambers, and meanwhile, a large amount of manpower and material resources are consumed in construction, the control difficulty is increased, and the construction process quality and safety control are not facilitated.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides the heat recovery coke oven vault structure which is stable and easy to construct, the stability of the main wall and the oven top is increased, the construction is convenient when the vault of the carbonization chamber is built, and a large amount of manpower and material resources are saved.
In order to achieve the purpose, the invention adopts the following technical scheme:
a stable and easily constructed heat recovery coke oven vault structure comprises a main wall and a vault, wherein the main wall and the vault are built by main wall leather bricks, arch foot bricks, roof spanning bricks, arch roof bricks and positioning bricks; the main wall and vault combining position set up double-deck concave-convex cooperation locking structure, and main wall skin brick passes through concave-convex structure interlock locking with striding the crown brick, and the location brick between two hunch foot bricks passes through concave-convex structure interlock locking with striding the crown brick.
The upper layer and the lower layer of the main wall skin brick are occluded through the groove tongue.
The main wall upper portion wall leather brick is the overhanging type structure.
And a groove tongue is arranged between the positioning brick and the top-crossing brick.
The vault is built by wedge vault bricks with a big top and a small bottom, and the side surfaces between the vault bricks are matched by a ditch tongue.
Compared with the prior art, the invention has the beneficial effects that:
1) The main wall leather bricks and the roof-spanning bricks are locked through the concave-convex structure in an occluded manner, the positioning bricks between the arch foot bricks and the roof-spanning bricks are locked through the concave-convex structure in an occluded manner again, the stability of the furnace top structure is greatly improved, the arch foot bricks are fixed by the main wall in the horizontal direction through the positioning bricks, the arch foot bricks cannot slide or deviate in position when the arch top bricks of a single carbonization chamber are built, the construction is convenient, and a large amount of manpower and material resources are saved.
2) The upper layer and the lower layer of the main wall skin brick are occluded by the grooves and the tongues, so that the integral stability of the main wall is facilitated.
3) The wall leather brick at the upper part of the main wall is of an overhanging structure, plays a good role in supporting arch springing bricks and is beneficial to the overall stability of the vault.
4) According to the invention, the stability of the main wall and the vault structure is improved by additionally arranging the groove tongues among the brick layers between the positioning bricks and the roof spanning bricks.
5) The vault is built by wedge-shaped vault bricks with a large upper part and a small lower part, and the side surfaces between the vault bricks are additionally provided with the groove tongues for matching, so that the stability of the vault is improved.

Detailed Description
The following further describes embodiments of the present invention in conjunction with the attached figures:
as shown in figure 1, in the main wall and the vault of the existing heat recovery coke oven, no interlayer matching structure exists between the brick skin on the upper part of the main wall and the roof-spanning brick, and between the roof-spanning brick and the arch foot brick, so that the sliding and the deviation are easy to occur, the brick joint of the arch roof brick is not uniform, the vault sinks, the elevation is not easy to control, and the construction quality can not be ensured.
As shown in fig. 2 and 3, the main wall leather bricks 1 and the roof-spanning bricks 3 are locked by occlusion through the concave-convex structure, the positioning bricks 5 between the arch foot bricks 2 and the roof-spanning bricks 3 are locked by occlusion again through the concave-convex structure, the stability of the furnace roof structure is greatly increased, the positioning bricks 5 enable the arch foot bricks 2 to be fixed by the main wall in the horizontal direction, and when the single carbonization chamber arch top bricks 4 are built, the positions of the arch foot bricks 2 can not slide and shift.
