Abstract
The utility model provides a novel coke dry quenching boiler which comprises a boiler body, wherein the boiler body is divided into a pre-storing section, an inclined way section and a cooling section from top to bottom, wherein the outer side of the lower section of the pre-storing section is provided with an outer wall, a ring-shaped air way is formed between the outer wall and the inner wall of the boiler body, and a slide gap is formed at a connecting surface between the inner wall and the outer wall, so that the inner wall of the boiler body can slide relative to the outer wall along with the axial direction of the boiler body. The heat swelling power of the inner wall can be released due to the slide gap of the boiler body, so that the load force of a bracket can be reduced, furthermore, the service life of the bracket can be prolonged, the overhaul efficiency can be reduced, and the production efficiency can be improved.
Description
Technical field
The utility model belongs to the coking field, is specifically related to the dried stove that puts out of a kind of novel coke.
Background technology
The dry coke quenching method is to utilize colder recycle gas to carry out heat exchange dried putting out in the stove with red Jiao; The recycle gas that absorbs red burnt heat imports and reclaims heat in the boiler; Produce steam, recycle gas carries out heat exchange through cooling, dedusting after blower fan returns dried putting out once more in the stove, so repeatedly circulation.The method of this production coke not only can reclaim red Jiao's sensible heat, reduces the discharging of pollutent, and can improve the quality of coke.Therefore, the dry coke quenching method obtains fast development in recent years.
Typical dry coke quenching auxiliary comprises equipment such as body of heater, disposable dust remover and boiler.The recycle gas that is used for quenching gets into boiler after the disposable dust remover dedusting after body of heater is discharged.Fig. 1 is the typical dried structure diagram that puts out stove.As shown in Figure 1, the dried stove that puts out comprises body of heater 1, and body of heater is divided into the section of prestoring 11, chute section 12 and cooling section 13 from top to bottom successively.Wherein, the section of prestoring 11 comprises tapered zone 11a and straight section district 11b from top to bottom, and the outside of 11b is provided with annular air channel exterior wall 15 in the straight section district, exterior wall 15 and form annular air channel 14 between 17 as the interior wall (the straight section district 11b part of body of heater) of body of heater 1.The bottom of annular air channel 14 is connected with chute section 12, and particularly, the bottom of annular air channel 14 is positioned at bracket 16.
Put out in the stove operational process dried, bracket 16 not only will bear the loading such as annular air channel interior wall 17 and annular air channel exterior wall 15, but also will under frequent temperature fluctuation, bear the wearing and tearing with the coke dust of washing away of gas.The more important thing is; Because interior wall 17 is different with the temperature of exterior wall 15; Make interior wall 17 body of heater axially with the expansion that makes progress of footpath all greater than exterior wall 15, thereby cause exterior wall 15 to be applied to the thermal expansion force that body of heater axially makes progress with the footpath to interior wall 17, promptly exterior wall 15 applies downward and inside thermal expansion force to interior wall 17; This not only causes the delivery position place of interior wall 17 and exterior wall 15 to damage easily, and has increased the carrying capacity of the bracket 16 that is used to support interior wall 17.And bracket 16 is overhauled difficulty, and the expense of overhauling is high, the time is long, and this will inevitably reduce the dried service efficiency of putting out stove.
In addition, the collar tie beam 22 that is used to support interior wall 17 in chute section 12 is supported by bracket 17, and collar tie beam 22 is fixed on the upper surface of bracket 17.In actual use, because collar tie beam 22 can't directly upwards move at body of heater with respect to bracket 17, the thermal expansion of collar tie beam 22 must increase the carrying capacity that bracket 17 directly makes progress at body of heater, and this will increase the damage intensity of bracket 17.Although the technician attempts anti-ly to wash away through adopting, mullite silicon carbide brick wear-resisting, that rapid heat cycle is functional and intensity is higher is built bracket 16 by laying bricks or stones; But the damage using 1 year left and right sides bracket 16 is still very serious; Like refractory brick cracking, even the bracket phenomenon of collapsing appears.
In addition, in actual use, the interior wall 17 of annular air channel damage phenomenons such as bulge occur easily owing to receive washing away and wearing and tearing, the pressure of coke and the effect of thermal expansion force of coke.In addition, the crossbeam (not shown) and the collar tie beam 22 that are used for lateral brace collar tie beam 22 closely cooperate, when collar tie beam 22 when body of heater radially expands, the carrying capacity of crossbeam increases, and not only damages collar tie beam 22 easily, and damages crossbeam easily.
The utility model content
For one of addressing the above problem, the utility model provides a kind of novel dried stove that puts out, and it not only can improve the interior wall of annular air channel and the work-ing life at interior wall and exterior wall delivery position place, and the work-ing life that can improve bracket.
The technical scheme that is adopted that solves the problems of the technologies described above provides the dried stove that puts out of a kind of coke; Comprise body of heater; Said body of heater is divided into the section of prestoring, chute section and cooling section from top to bottom successively; The outside at the hypomere of the said section of prestoring is provided with exterior wall; And make between said exterior wall and the interior wall and form annular air channel as said body of heater, at the top of said annular air channel and the connecting position place that is positioned at said interior wall and said exterior wall be provided with sliding joint, by said sliding joint make said body of heater interior wall can with respect to said exterior wall said body of heater axially on slide.
Preferably; Chute section at said body of heater; Said interior wall is supported by collar tie beam; Said collar tie beam is supported by bracket, and be used to support said collar tie beam bracket upper surface and be level and smooth face with the lower surface of the collar tie beam of the upper surface joint of said bracket, said collar tie beam can upwards slide in the footpath of said body of heater at the upper surface of said bracket.
Preferably, at the collar tie beam that is used for the said interior wall of longitudinal ligament be used for being provided with dilatation joint between the crossbeam of the said collar tie beam of lateral brace, said dilatation joint is the space that said collar tie beam is provided at the thermal expansion that said body of heater directly makes progress.
Wherein, said annular air channel exterior wall adopts mullite brick, clay brick and insulating brick to build by laying bricks or stones to form from inside to outside successively.
Wherein, said mullite brick is an A level mullite brick.
Wherein, be provided with air inlet port or vision slit at the top of said annular air channel.
The utlity model has following beneficial effect:
