Abstract

The utility model relates to an oven body structure capable of adjusting the heating uniformity in the length direction of a coke oven from the lower part. The oven body structure is characterized in that a check grate for adjusting the gas passing through the sectional area is arranged at the bottom of a regenerative chamber at the top of a bottom flue, and the sizes of check grate holes are adjusted by increasing or reducing sliding bricks to the check grate holes from a basement; each regenerative chamber is divided into a plurality of cells in the length direction, so as to form a plurality of gas passages; and gas and air are fed in from the same side of the bottom flue of the regenerative chamber, that is, gas and air are fed in through a bottom flue on the coke side or a bottom flue on the machine side. The utility model has the benefits that the oven body structure has a reasonable structure, and the check grate for adjusting the gas passing through the sectional area is arranged at the bottom of the regenerative chamber at the top of the bottom flue, so 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 more reasonable; and the regenerative chamber adopts a split structure, so that the oven body structure is more favorable for distribution of gas, avoids the phenomenon of local high temperature due to the unreasonable gas distribution and effectively improves the product quality of the coke oven.

Description

A kind ofly can regulate the furnace binding of coke oven length from the bottom to heating uniformity

Technical field

The utility model relates to a kind of novel furnace binding of underjet coke oven and regulates the method for coke oven length to heating uniformity from the bottom.

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 utility model provides a kind of from regulating the furnace binding of coke oven length to heating uniformity from the bottom, and this structure can realize convenient adjusting of coke oven difference quirk coal gas amount smoothly, and reaches long purpose to homogeneous heating.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind ofly can regulate the furnace binding of coke oven length, comprise the regenerator bottom flue, the grate brick of adjustable gas by sectional area is set in the bottom of the top of bottom flue regenerator from the bottom to heating uniformity.

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.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.

Compared with prior art, the beneficial effects of the utility model are:

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 embodiment of the present utility model is described further:

See Fig. 1-Fig. 5, a kind ofly can regulate the furnace binding of coke oven length from the bottom to heating uniformity, comprise regenerator bottom flue 1, 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.

The utility model coke oven regenerator top links to each other with the combustion chamber by chute, the bottom links to each other with waste gas valve, coal gas and air from bottom flue enter the flue burning after regenerator 5 preheatings, enter regenerator again by the decline quirk then, discharge through bottom flue 1.
