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 coke 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, in 6m or less coke oven, general use from furnace roof peephole adjusts the upper of chute mouth adjusting brick
Tune mode, and it is greater than the coke oven of 6m for carbonization chamber height, it is relatively difficult using up-regulation mode, therefore generally use regenerative chamber tune
Save the mode that brick is lowered.But the mode that regenerative chamber is lowered is twice than chute mouth up-regulation mode workload, and is lowered hole and opened
While also result in blast furnace ash dust evolution, seriously pollute working environment.
In addition, twinflue waste gas circulation amount influence the height of flue flame, coke it is high to heating uniformity,
The production quantity of NOx even carbonization chamber furnace top space temperature, is a critically important parameter, but above two regulative mode all without
Method realizes the adjusting to waste gas circulation amount.And the gas-flow resistance crossed at hole can influence the buoyancy difference of twinflue, Jin Erying
Ring waste gas circulation amount.
Summary of the invention

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 is a kind of across the adjustable coke oven construction in hole, and the coke oven is certainly
Under supreme be successively arranged regenerative chamber 4, 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；It is described to cross over 21 lower section of hole, 22 top one of twinflue partition wall
Side or two sides are equipped with boss 24, which extends in corresponding vertical airflow channel into twinflue, removable on boss 24
It is equipped with adjusting brick 23 dynamicly.
The extension of the boss 24 is less than or equal to the 1/2 of vertical airflow channel corresponding direction width, set on boss 24
There is brick slot 27, adjusting brick 23 is fastened in brick slot 27.
The adjusting brick 23 is zero to muti-piece.
The top of the adjusting brick 23 sets dog hole 26, for cooperating with the hitcher protruded into from peephole 11, realizes adjusting brick
23 movement and position are put.
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, bottom
Thickness is matched with 27 size of brick slot.
It is described in the utility model to cross over the adjustable coke oven construction in hole, it is smash for pushing up dress coke oven, tamping coke furnace or top dress
Gu integrated coke oven.
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, the size and location that hole 21 is crossed in each flue 25 is determined by theoretical calculation；And
The size of adjusting brick 23 is determined according to the size across hole 21；
2) coke oven is during normal production, constant across 21 size of hole, does not adjust；
3) it when coke oven production fluctuates, by changing the position of adjusting brick 23 and quantity on boss 24, adjusts and crosses over
Gas-flow resistance at hole 21；It is specifically divided into following several situations：
A. when briquette coking heat consumption is reduced or when coking time of coke oven extends, 25 air demands of flue are reduced, this
The quantity of adjusting brick 23 on Shi Zengjia boss 24；
B. when carbonization chamber headspace temperature is excessively high, increase the quantity of adjusting brick 23 on boss 24, followed by reducing exhaust gas
Circular rector shortens the length of flame, reduces carbonization chamber headspace temperature；
C. when briquette height is deteriorated to heating uniformity, the quantity of adjusting brick 23 on boss 24 is reduced, is followed by increasing exhaust gas
Circular rector elongates the length of flame；
In the above adjustment process, the position of adjusting brick and quantity are all in accordance with need at the interior leap hole 21 of each flue 25 of coke oven
It individually to adjust.
Described crosses over hole adjusting method, when making integrated coke oven firm by ramming for pushing up dress, is changed to make refining firm by ramming when by top dress coking
Jiao Shi, briquette taper change, by changing the quantity of adjusting brick 23 on each 25 inner convex platform 24 of flue, guarantee coke oven it is long to
Heating uniformity.
In the utility model, the length of the adjusting brick 23 is less than 11 corresponding direction of furnace roof 1 and peephole to full-size
Width or diameter.Brick slot 27 is set on the boss 24 to be stuck in adjusting brick 23 wherein, can be avoided adjusting brick 23 because of airflow function
Topple over forward or backward.
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.
