Abstract
The utility model relates to a clean type heat recovery coke oven three-heart dome furnace roof structure, its characterized in that: the furnace top area of the carbonization chamber adopts a three-center circular arch structure furnace top curve built by silicon bricks, and the three-center circular arch structure furnace top curve consists of three circular arcs of R1, R2 and R3 with different centers and circular arc radiuses. The utility model discloses clean type heat recovery coke oven three-heart dome furnace roof structure has characteristics such as reasonable in design, simple structure compactness, sealed effectual. The chord height of the original recovery coke oven can be reduced by 40 percent, and the problems that the chord height of a single-circle-center arch structure is large, the top is easy to crack after the oven is expanded, the sealing effect is poor, the thrust to a main wall is large, the environmental pollution is caused, the economic benefit of an enterprise is reduced, and the like are solved.
Description
Technical Field
The utility model belongs to a clean heat recovery coke oven roof structure in the metallurgical industry, and relates to a three-center arched roof structure of a clean heat recovery coke oven.
Background
At present, the furnace top structure of the carbonization chamber of the traditional heat recovery coke oven in the prior art in the domestic metallurgical industry adopts a single-circle-center arch structure built by refractory bricks, and the arch structure exists: the chord height is large, the top is easy to crack after the baking furnace is expanded, the sealing effect is poor, the thrust to the main wall is large, and the like.
Disclosure of Invention
The utility model overcomes the above-mentioned defect that exists, the purpose is that the chord height ratio is bigger for solving single centre of a circle domes, easy fracture, sealed effect poor, and to the great scheduling problem of main wall thrust in baker inflation back top, provide a clean type heat recovery coke oven three-centre circle domes roof structure.
The content of the three-center arched furnace top structure of the clean heat recovery coke oven is briefly described as follows:
the invention discloses a three-center circular arch-shaped furnace top structure of a clean heat recovery coke oven, which is characterized in that: the furnace top area of the carbonization chamber adopts a three-center circular arch structure furnace top curve built by silicon bricks, and the three-center circular arch structure furnace top curve consists of three circular arcs of R1, R2 and R3 with different centers and circular arc radiuses.
The utility model discloses clean type heat recovery coke oven three-heart dome furnace roof structure has characteristics such as reasonable in design, simple structure compactness, sealed effectual. The chord height of the original recovery coke oven can be reduced by 40 percent, and the problems that the chord height of a single-circle-center arch structure is large, the top is easy to crack after the oven is expanded, the sealing effect is poor, the thrust to a main wall is large, the environmental pollution is caused, the economic benefit of an enterprise is reduced, and the like are solved.
Drawings
FIG. 1 is a schematic structural view of a three-center dome-shaped roof of a clean heat recovery coke oven;
in the figure: 1 is a carbonization chamber, 2 is a furnace top area, and 3 is a furnace top curve with a three-center circular arch structure.
Detailed Description
The three-center arched furnace top structure of the clean heat recovery coke oven of the utility model is realized in the way, and the following description is combined with the attached drawings for details.
According to the figure 1, the utility model discloses clean type heat recovery coke oven three-heart dome furnace roof structure adopts three-heart dome structure furnace roof curve 3 that silica brick built by laying bricks in the furnace roof district 2 of carbomorphism room 1, and three-heart dome structure furnace roof curve 3 comprises three different centre of a circle and the circular arc of the radial R1 of circular arc, R2 and R3. The three-center circular arch top structure can reduce the chord height of the original recovery coke oven by 40 percent, can effectively prevent the arch crown from cracking caused by linear expansion, and reduce the horizontal thrust. Not only the strength and the tightness of the furnace body are enhanced, but also the service life of the furnace body is prolonged.
The utility model belongs to a clean heat recovery coke oven top structure in the metallurgical industry, which has the characteristics of reasonable design, simple and compact structure, good sealing effect and the like. The problems that the chord height of a single-circle-center arch structure is large, the top of the baking furnace is easy to crack after expansion, the sealing effect is poor, the thrust to a main wall is large, and the environmental pollution and the economic benefit of enterprises are reduced are solved.
