Description
Technical field
The utility model relates to coking by coke oven technical field more particularly to a kind of leap adjustable coke oven constructions in hole.
Background technique
The long uniformity and product quality that coke oven heating is directly affected to the distribution of tolerance of coke oven, by coke oven self structure
Limitation is grown to tolerance and usually requires to be adjusted by adjustment structure or regulating device.
Currently, carbonization chamber height is in 6m or less coke oven generally using the up-regulation for adjusting chute mouth adjusting brick from furnace roof peephole
Mode, and after carbonization chamber height is greater than 6m, it is relatively difficult using up-regulation mode；Thus carbonization chamber height is greater than the large size of 6m
Coke oven is general by the way of the downward of regenerative chamber adjusting brick.But the mode that regenerative chamber adjusting brick is lowered is than chute mouth adjusting brick
The mode workload of up-regulation is twice, and lowers the dust evolution that blast furnace ash is also resulted in while hole is opened, and seriously pollutes work
Make environment.In addition, the waste gas circulation amount of twinflue directly affect the height of flue flame, coke it is high to homogeneous heating
Property, NOx production quantity even carbonization chamber furnace top space temperature, be a critically important parameter, but above-mentioned regulative mode is all real
Now not adjusting to waste gas circulation amount.And by the change across gas-flow resistance at hole, the buoyancy of twinflue can be influenced
Difference, and then change waste gas circulation amount.
Summary of the invention
The utility model provides a kind of leap adjustable coke oven construction in hole, across setting adjusting brick at hole, passes through tune
Knothole adjusts the position of adjusting brick and quantity at this, and each flue can be adjusted individually, to realize focusing furnace superintendent to adding
The adjusting of thermal uniformity and waste gas circulation amount.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of to cross over the adjustable coke oven construction in hole, the coke oven includes the regenerative chamber set gradually from bottom to top, chute, combustion
Burn room and furnace roof；Combustion chamber is divided into multiple flues by flue partition, and flue is twinflue, and twinflue is by duplex
Quirk partition wall separates, and top across hole by being connected to；It forms and is equipped with peephole at the top of each quirk of twinflue；It is described across
More the lower section in hole, twinflue are equipped with groove every coping, and for placing adjusting brick, the top of groove is equipped with adjustment hole, adjusts
Knothole passes through furnace roof and is connected to outside.
The adjusting brick is zero to muti-piece.
The adjusting brick be equipped with dog hole, for being protruded into self-regulated knothole hitcher cooperation, realize adjusting brick movement and
It puts position.
The adjusting brick it is long to full-size be less than the minimum widith or diameter of adjustment hole.
The thickness direction of the adjusting brick is low wide and up narrow, top thickness 10-100mm.
Compared with prior art, the utility model has the beneficial effects that
1) a kind of regulating measure is increased for coke oven combustion system, flue air inflow can be changed according to production requirement,
Relative to the adjusting method of traditional regenerative chamber adjusting brick, the workload of half is saved, facilitates the production operation of coke oven；
2) tolerance in each twinflue in combustion chamber can be adjusted individually, guarantee the long uniformity to heating of coke oven；
3) by adjusting flue waste gas circulation amount, uniformity, carbonization chamber headspace temperature of the briquette height to heating are realized
The control and adjusting of the production quantity of degree and NOx；
4) it is suitable for top dress coke oven, tamping coke furnace and top dress and makes integrated coke oven firm by ramming；It is particularly suitable for top dress and makes one firm by ramming
Change coke oven, furnace superintendent of focusing when coke making process changes effectively is adjusted to heating uniformity.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
As shown in Figure 1-Figure 3, described in the utility model a kind of across the adjustable coke oven construction in hole, the coke oven includes under
The supreme regenerative chamber 4 set gradually, chute 3, combustion chamber 2 and furnace roof 1；Combustion chamber 2 is divided into multiple vertical fire by flue partition
Road 25, flue 25 are twinflue, and twinflue is separated by twinflue partition wall 22, and top across hole 21 by being connected to；Group
Peephole 11 is equipped at each quirk top of twinflue；The lower section across hole 21, twinflue partition wall 22 top
Portion is equipped with groove 27, and for placing adjusting brick 23, the top of groove 27 is equipped with adjustment hole 12, and adjustment hole 12 is across furnace roof 1 and outside
Portion's connection.
The adjusting brick 23 is zero to muti-piece.
The adjusting brick 23 is equipped with dog hole 26, and adjusting brick 23 is realized in the hitcher cooperation for protruding into self-regulated knothole
It puts mobile and position.
The adjusting brick 23 it is long to full-size be less than the minimum widith or diameter of adjustment hole 12.
As shown in Figure 4, Figure 5, the thickness direction of the adjusting brick 23 is low wide and up narrow, top thickness 10-100mm.
It is described in the utility model a kind of across the adjustable coke oven construction in hole, it is filled for pushing up dress coke oven, tamping coke furnace or top
Make integrated coke oven firm by ramming.
Hole adjusting method is crossed over based on coke oven construction described in the utility model, is included the following steps:
1) before coke oven production, according to theoretical calculation determine in twinflue cross over hole 21 size and location, and according to
Size across hole 21, adjustment hole 12 determines the size of adjusting brick 23；
2) coke oven is during normal production, constant across 21 size of hole, does not adjust；
3) when coke oven production fluctuates, by changing position and quantity across adjusting brick 23 at 21 holes, adjust across
Gas-flow resistance more at hole 21；It is specifically divided into following situation:
A. when briquette coking heat consumption is reduced or when coking time of coke oven extends, 25 air demands of flue are reduced, this
Quantity of the Shi Zengjia across adjusting brick 23 at hole 21；
B. when carbonization chamber headspace temperature is excessively high, increase the quantity across adjusting brick 23 at hole 21, by reducing exhaust gas
Internal circulating load shortens the length of flame, reduces carbonization chamber headspace temperature；
C. when briquette height is deteriorated to heating uniformity, the quantity across adjusting brick 23 at hole 21 is reduced, is followed with increasing exhaust gas
Circular rector elongates the length of flame；
In the above adjustment process, in each flue of coke oven 25 across the position of adjusting brick 23 at hole 21 and quantity all in accordance with
It needs individually to adjust.
Described crosses over hole adjusting method, makes integrated coke oven firm by ramming suitable for top dress coke oven, tamping coke furnace and top dress；Wherein
When making integrated coke oven firm by ramming for pushing up dress, when being changed to tamping coking by top dress coking, briquette taper changes, and passes through change
Across the quantity of adjusting brick 23 at hole 21 in each flue 25, guarantee that coke oven is long to heating uniformity.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
