Description
Technical field
The present invention relates to coke oven technical field more particularly to a kind of adjustable coke oven construction of heat levels and heat levels tune
Section method.
Background technology
The difference on the distance between coke furnace carbonization chamber top and coke oven vertical flame path top is known as the heat levels of coke oven, and heat levels are
A significant dimensions in coking furnace shaft structure.Heat levels are too small, and carbonization chamber headspace temperature is excessively high, is unfavorable for raisingization
The quality and yield of product can also increase roof carbon generation；Heat levels are too big, can reduce top charge of coke temperature, influence coke
Uniformly ripening above and below cake.
Currently, the heat levels of most of coke oven are preset parameters, adjustment criteria fire can only be passed through in actual production process
The modes such as channel temp change coke quality, and adjustment criteria fire path temperature can influence other manufacturing parameters such as coking time,
And briquette height cannot be fundamentally solved to the ripe uniformity.7.63 meters of top dress coke ovens that German Wood Company is designed and developed, tool
Have it is adjustable cross over hole, across hole points upper and lower 2 layers, upper and lower 2 layers across having one piece of circular mill on the flues between hole
Brick adjusts heat levels and furnace roof space temperature by adjusting the opening and closing of mill brick.But since mill brick is excessive, adjust
Get up relatively difficult, and can not accurately be adjusted；Therefore in coke oven actual production excessively substantially will not to mill brick into
Row is adjusted, to lose the effect that upper and lower layer crosses over hole.In addition, when blocking flue completely by mill brick, actually
Also peephole has just been covered, has led to not carry out hand-operated temperature-measuring to flue.
Invention content
The present invention provides a kind of adjustable coke oven construction of heat levels and heat levels adjusting methods, can be to passing through
The upper and lower 2 layers throughput across hole is accurately adjusted, and changes the heat levels of coke oven, to adjust carbonization chamber headspace
Temperature；Its adjustment process is simple and convenient, and does not influence the measurement of flue temperature.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of adjustable coke oven construction of heat levels, the coke oven include the regenerative chamber set gradually from bottom to top, chute,

Adjacent 2 flues are separated by flue partition, and flue is twinflue, passes through twinflue partition wall point between twinflue
Every, being set across hole at the top of flue makes twinflue be connected to, and is made of across hole across hole and lower layer across hole upper layer, upper,
Lower 2 layers set interlayer across between hole；The one or both sides of the interlayer are equipped with boss, the correspondence on the flue partition of respective side
Position also is provided with boss, and one-to-one 2 boss, which are matched, is combined into supporting table；Polylith is movably disposed at across hole adjusting brick
On supporting table, and it can be closed by the gas channel part of corresponding position or all.
It is described to be equipped with dog hole across hole adjusting brick top, coordinate with the hitcher that can stretch into flue by peephole, it is real
It now crosses over the movement of hole adjusting brick and position is put.
The adjustable coke oven construction of a kind of heat levels makes one firm by ramming for pushing up dress coke oven, tamping coke furnace or top dress
Change coke oven.
Heat levels adjusting method based on the coke oven construction, includes the following steps：
1) when Coke-oven Design, the upper and lower 2 layers specific size and relative position across hole, and root are determined according to theoretical calculation
According to setting across the cross sectional dimensions of gas channel at the adjusting brick of hole, the specific size across hole adjusting brick and each vertical fire are determined
The required quantity across hole adjusting brick in road；
2) it when coke furnace building, is placed on required in twinflue across hole adjusting brick according to the result of calculation of step 1)
Supporting table on；
3) coke oven normally produces；
4) it when coke oven combustion uses the coal charge of different shrinkages, is put into twinflue by peephole with hitcher
It adjusts by changing position and the quantity of supporting table upper spanning hole adjusting brick across hole adjusting brick and crosses over hole by upper and lower 2 layers
Throughput in addition the gas channel of completely enclosed corresponding position realized at the top of carbonization chamber to change the heat levels of coke oven
The accurate adjustment of space temperature；
5) when needing to measure flue bottom temp, if on supporting table across between having between the adjusting brick of hole enough
Gap can be measured directly；If the gas channel of corresponding position has been completely enclosed across hole adjusting brick, pass through hitcher
Intermediate one piece is temporarily removed across hole adjusting brick, waits for that this playbacking across hole adjusting brick again after thermometric.
When the step 2) coke furnace building, being adjusted across hole for the completely enclosed corresponding number of gas channel will be realized
Brick is all placed on supporting table, wherein being placed in lower layer across hole adjusting brick for what initial air-flow was adjusted, remaining crosses over hole
Adjusting brick is placed in upper layer, is taken at any time when coke oven being facilitated to adjust heat levels.
Compared with prior art, the beneficial effects of the invention are as follows：
1) throughput for crossing over hole by upper and lower 2 layers can accurately be adjusted, changes the heat levels of coke oven, from
And realize the accurate adjusting to carbonization chamber top space temperature；Coke oven is set to be suitable for the coal charge with different shrinkages；
2) adjustment process is simple and convenient, and does not influence the measurement of flue temperature；
3) it is suitable for top dress coke oven, tamping coke furnace and top dress and makes integrated coke oven firm by ramming.
