Abstract

The utility model discloses a jack arch and overhead brick combination structure of a dry coke quenching chamber and relates to a dry coke quenching furnace used in the coking production of a steel industry, in particular to a dry quenching chamber structure in the dry coke quenching furnace. The jack arch and overhead brick combination structure is arranged above a chute and is fixed on a corbel of the chute, and the bottom surface of the jack arch and overhead brick combination structure is of an arch structure. The bottom of the jack arch and overhead brick combination structure of the dry coke quenching chamber is arched, so the pressure can be dispersedly transferred to the corbel better according to the mechanics principle of an arch bridge, the impact of super-heat inert gas with coal particles can be effectively lowered, and the service life of the jack arch and overhead brick combination structure can be greatly prolonged.

Description

The dried jack arch of putting out the chamber of dry coke quenching is crossed the dome brick unitized construction
Technical field
The utility model relates to employed coke dry quenching furnace in a kind of steel industry coking production, refers to the dried structure of putting out the chamber in a kind of coke dry quenching furnace particularly.
Background technology
Dry coke quenching technology is for traditional wet is handled red burnt technology; Be to use rare gas element the coke of red heat is cooled off and discharges coke at coke dry quenching furnace; After the heat exchange rare gas element after first dedusting in boiler with the de-mineralized water heat exchange; Produce steam, the process of recycle under the suction of final dusting at recirculation blower.Dry coke quenching technology becomes the technology that clearly must adopt in the Chinese coking industry permit standard because it has advantages such as the energy of recovery, protection environment, raising coke quality.
Coke dry quenching furnace is dried to put out that the chamber is divided into cooling zone, chute district, annular passage district, the district prestores; The annular passage district is on top, chute district; Be to rely on the support of chute bracket to form the passageway of being made up of two sides refractory materials masonry, send into disposable dust remover will cool off red heat coke rare gas element afterwards, the interior walling gross weight in full annular air channel has surpassed 200 tons; Cross dome brick through jack arch and be connected with the chute bracket, jack arch is crossed the basis that dome brick is exactly a walling in the full annular air channel.
Shown in Figure 2, jack arch is in the past crossed dome brick unitized construction 3 ' and is adopted six brick combinations to build by laying bricks or stones, and bottom margin and bracket 2 ' are gone up planar horizontal, and owing to the pressure of walling in the annular passage, the stress of generation can not be evenly distributed on the bracket fully in the use; Owing to receive the expansion of thermal stresses, hoop stress caused the fracture of dome brick lower edge, came off; Simultaneously, this position is sitting at chute 1 ' top, and the high hot inert gas that is had pulverized coal particle impacts, and has accelerated the damage of bottom margin.
The utility model content
The technical problem that the utility model will solve is to overcome the defective that existing jack arch is crossed the dome brick unitized construction, provides a kind of arc jack arch that has reduced the impact of high hot inert gas and alleviated stress to cross the dome brick unitized construction.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
The dried jack arch of putting out the chamber of dry coke quenching is crossed the dome brick unitized construction, and said jack arch is crossed the dome brick unitized construction and is positioned at the chute top, is fixed on the chute bracket, and the bottom surface that said jack arch is crossed the dome brick unitized construction is domes.
Further, said jack arch is crossed the dome brick unitized construction and is built by laying bricks or stones by the refractory brick combination that the polylith bottom surface is arcual, radian coupling.
Beneficial effect: the dry coke quenching of the utility model is dried to be put out the chamber jack arch to cross the bottom of dome brick unitized construction is arch; Utilize the mechanics principle of arch bridge; Better pressure is disperseed to be passed on the bracket; And reduced the impact of the high hot inert gas that has pulverized coal particle effectively, improved its work-ing life greatly.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification sheets, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation that existing jack arch is crossed the dome brick unitized construction;
Fig. 2 is the structural representation that the utility model jack arch is crossed the dome brick unitized construction.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Embodiment 1
As shown in Figure 1; The dried jack arch of putting out the chamber of dry coke quenching is crossed the dome brick unitized construction, and jack arch is crossed dome brick unitized construction 3 and is positioned at chute 1 top, and is fixed on the chute bracket 2; Its bottom surface is domes, and this crosses dome brick unitized construction 3 is to be built by laying bricks or stones by the refractory brick combination that 6 bottom surfaces are arcual, radian coupling.
Its making method is: with the brick body combination of prior art, calculate the bracket position, confirm the sagitta and the summit of arch radian, confirm brick type, change Mold Making afterwards again.
What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims (2)

1. the dried jack arch of putting out the chamber of dry coke quenching is crossed the dome brick unitized construction, and said jack arch is crossed the dome brick unitized construction and is positioned at the chute top, is fixed on the chute bracket, and it is characterized in that: the bottom surface that said jack arch is crossed the dome brick unitized construction is domes.
2. the dried jack arch of putting out the chamber of dry coke quenching according to claim 1 is crossed the dome brick unitized construction, it is characterized in that: said jack arch is crossed the dome brick unitized construction and is built by laying bricks or stones by the refractory brick combination that the polylith bottom surface is arcual, radian coupling.
