Abstract
The invention relates to a method capable of adjusting heating uniformity of a coke oven in a length direction from a lower portion and a novel oven body structure. The invention is characterized in that a grate brick capable of adjusting gas passing section area is arranged at the bottom of a top heat storage chamber of a small flue and the sizes of holes of the grate brick are adjusted by adding or subtracting adjusting bricks to or from the holes of the grate brick at a cellar. Each heat storage chamber is divided into a plurality of unit cells along the length direction; and each heat storage chamber is divided into multiple gas channels in the length direction. Coal gas and air are supplied from the same side of the small flue of the heat storage chamber; namely, the coal gas and the air are both supplied from a small flue at a coke side or a small flue at a machine side. The invention has the advantages that the problem of heating uniformity in the length direction of the coke oven is solved and the temperature of a flame path is more uniform and reasonable because the structure is reasonable and the grate brick capable of adjusting the gas passing section area is arranged at the bottom of the top heat storage chamber of the small flue; and the heat storage chamber which is in a cellular structure is more beneficial to distribution of gas quantity, avoids local high temperature caused by unreasonable distribution of the gas quantity and is capable of effectively increasing the product quality of the coke oven.
Description
Technical field
The present invention relates to a kind of novel furnace binding of underjet coke oven and regulate the method for coke oven length from the bottom to heating uniformity.
Background technology
In the prior art, the working process of coke oven is: coal gas and air enter the bottom flue of regenerator respectively from the mechanical coke both sides, enter regenerator by the grate brick, through the coal gas and the burning of air admission flue of preheating.Long to the homogeneity that heats for guaranteeing, often in the flue bottom, chute outlet position is arranged and is regulated brick, amasss by the adjusting open section and adjusts the coal gas sendout that enters different quirks.Waste gas after burning enters regenerator through another decline quirk again, enters bottom flue through the grate brick, from mechanical coke both sides waste gas valve, enters both sides and divides flue.
Along with the development that coke oven maximizes, the distance of coke oven furnace roof at the bottom of the flue is also more and more higher, puts from the furnace roof peephole and regulates brick at the bottom of the flue, reaches the purpose of adjusting tolerance, can't realize.The length of coke oven is regulated long also more and more difficult to heating uniformity to also more and more longer.
Summary of the invention
The purpose of this invention is to provide a kind ofly from can regulating method and the furnace binding of coke oven length to heating uniformity from the bottom, this structure can realize convenient adjusting of the different quirk coal gas of coke oven amount smoothly, and reaches long purpose to homogeneous heating.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind ofly can regulate the method for coke oven length from the bottom to heating uniformity, the grate brick of adjustable gas by sectional area is set in the bottom of the top of bottom flue regenerator, the size adjustment in this grate brick hole realizes that by regulating brick at the vault place to grate brick hole plus-minus this structure can reach regenerator length to the purpose of distributing tolerance to regulate.
To being divided into some cells, each regenerator is divided into a plurality of gas passages to described each regenerator, and the tolerance that each gas passage enters can be regulated separately along long.
Separate with dividing wall between described a plurality of gas passage, and the gas passage that forms of each cell can be with a pair of or two pairs of quirks are corresponding.
Coal gas and air infeed from the homonymy of regenerator bottom flue, and promptly coal gas and air infeed by coke side bottom flue or pusher side bottom flue.
Realize the furnace binding of described method, the grate brick of adjustable gas by sectional area is set in the bottom of the top of bottom flue regenerator, the size adjustment in this grate brick hole realizes by the adjusting brick size that is arranged in the grate brick hole.
To being divided into some cells, each regenerator is divided into a plurality of gas passages to described each regenerator, and the tolerance that each gas passage enters can be regulated separately along long.
Separate with dividing wall between described a plurality of gas passage, and the gas passage that forms of each cell can be with a pair of or two pairs of quirks are corresponding.
Be provided with coal gas and air input channel in the same side of regenerator bottom flue.
Compared with prior art, the invention has the beneficial effects as follows:
1) rational in infrastructure, the grate brick of adjustable gas by sectional area is set in the bottom of the top of bottom flue regenerator, for the long situation of the distance at the bottom of maximization coke oven furnace roof and the flue, also can realize the adjusting of tolerance smoothly; Solved the problem of coke oven length, made fire path temperature more evenly rationally to heating uniformity;
2) because regenerator is a cell structure, be divided into a plurality of gas passages, more help the distribution of tolerance, and the tolerance that each gas passage enters can be regulated separately.This structure has avoided because the localized hyperthermia that the tolerance unreasonable distribution causes, and can effectively improve the quality product of coke oven;
3) adopted inflammable gas and combustion air to enter the bottom flue technology, reduced the quantity of waste gas lobe, reduced the difficulty that adds heat exchange, improved the environment of coke oven vault, had the investment of saving, simplify technology, improve the effect of environment from homonymy.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
See Fig. 1-Fig. 5, a kind of coking furnace shaft structure comprises bottom flue 1, and bottom flue 1 all is structure as a whole with main wall, single wall of regenerator 5, and the grate brick 2 of adjustable gas by sectional area is set in the bottom of the top of bottom flue 1 regenerator 5.The size adjustment in this grate brick hole 9 realizes that by regulating brick 10 at the vault place to grate brick hole plus-minus this structure can reach regenerator length to the purpose of distributing tolerance to regulate.Be provided with checker brick 3 heat storages in the regenerator 5.
See Fig. 3, to being divided into some cells, each regenerator is divided into a plurality of gas passages to each regenerator, and the tolerance that each gas passage enters can be regulated separately along long.With dividing wall 4 separately, this structure more helps the distribution of coal gas and air tolerance, and is more guaranteed to the quality of coke oven product between a plurality of gas passages.See Fig. 4, each cell gas passage can be with a pair of or two pairs of quirks are corresponding.
See Fig. 3, coal gas and air infeed from the homonymy of regenerator bottom flue 1, and promptly coal gas and air infeed by coke side bottom flue or pusher side bottom flue, discharged by the coexist pusher side or the coke side that coexists, or slave, burnt heteropleural are discharged respectively.This kind mode can reduce the quantity of waste gas lobe, has reduced the difficulty that adds heat exchange, has improved the environment of coke oven vault, has the investment of saving, simplifies technology, improves the effect of environment.
Coke oven regenerator of the present invention top links to each other with the combustion chamber by chute, and the bottom links to each other with waste gas valve, enters the flue burning from the coal gas of bottom flue and air after regenerator 5 preheatings, enters regenerator again by the decline quirk then, discharges through bottom flue 1.
