Abstract

The utility model discloses an anode baking furnace in the production field of anodes for aluminum, in particular to a flue wall structure of the anode baking furnace. The flue wall comprises a flue wall body and flue wall special shaped bricks, wherein, a broken line-shaped vertical brick work joint is arranged between the adjacent flue wall special shaped bricks on a same horizontal surface, and a high-temperature binding agent is arranged at the brick work joint of the adjacent flue wall special shaped bricks up and down for binding. The flue wall has the advantages that the broken line-shaped dry masonry vertical joints are taken as volatile matter channels, thereby preventing filling coke from being greatly sucked into a flue for combustion and effectively reducing the burning loss consumption of the filling coke. The flue wall improves the finished product rate of anode products, reduces the oxidation of the anode products during the cooling process, effectively solves the difficulty in the masonry construction and has simple structure and easy implementation.

Description

The quirk wall

Technical field

The utility model relates to the anode-baking furnace of aluminium anode production field, particularly relates to a kind of flue wall structure for anode baking furnaces.

Background technology

Anode roasting fire path wall is a primary structure of forming hopper, also is the main heat carrier of anode-baking process; Simultaneously, the high heating value fugitive constituent of discharging in the anode goods enters the passage of quirk burning, also is arranged on the quirk wall.So whether fire tunnel wall structure is reasonable, direct relation the quality of technical indicator such as flammable pollutant load in anode-baking quality, output, heat exhaustion and the flue gas.

Existing anode roasting fire path wall all is that the employing two ends are straight, the quirk wall brick of the female mouth structure of top and bottom belt is built by laying bricks or stones and formed.In order to make the fugitive constituent that overflows in the anode goods can enter the quirk burning smoothly, in the specific region on quirk wall surface, the seam mother-son mouth that crouches between quirk wall brick and the brick interlocks when building by laying bricks or stones, and adopts high temperature clay bonding to build by laying bricks or stones.And the upright brickwork joint between brick and the brick is not built refractory wass, adopts the method for laid dry to build by laying bricks or stones, and reserves the slit of certain width, enters the passage of quirk as fugitive constituent.The quirk wall of this structure in heat transferred hopper and goods in the quirk, also can make fugitive constituent enter the quirk burning smoothly by the upright brickwork joint of above-mentioned laid dry, and effective energy savings also reduces pollutant emission.But the fire tunnel wall structure of seam is found in this straight-through laid dry, has the shortcoming of following several respects: 1, Zhi Tong upright brickwork joint, be easy to the burnt quirk that sucks of the filling of surmising is for a short time burnt, and cause the burnt waste of filling big; 2, after the small powder degree inserts scaling loss, boiler face is filled the space that the bed of material forms straight-through hopper, quirk, easily sucks the boiler face fresh air, causes the oxidation of anode product surface, waste product can occur when serious; 3, in entering the furnace chamber of the state of cooling, forced cooling device will blast air in quirk, owing to have straight-through upright seam on the quirk wall, the cooling air is easy to enter the hopper that does not cool down fully as yet, causes the severe oxidation of anode product surface; 4, because building materials is manufactured error, the situation that can occur the upright seam of straight-through laid dry width overshoot width when building by laying bricks or stones, and, will bring the difficulty of manufacturing of quirk wall brick and building construction to strengthen because the inherent shortcoming of the upright seam of this straight-through laid dry is difficult to during construction remedy.

The utility model content

The utility model is exactly that a kind of quirk wall is provided in order to solve the problems of the technologies described above, purpose be solve that filling Jiao that the straight-through upright crack structure of existing anode roasting fire path wall laid dry brings enters easily that quirk, scaling loss are big, hopper inserts cover layer attenuate, cooling air easily suck hopper and cause the oxidation of anode product and difficulty of construction big, the wide seam defect of formation such as is difficult for remedying at problem.

Be achieved in that the quirk wall for reaching above-mentioned purpose the utility model, comprise quirk body of wall, quirk wall special form brick, it is characterized in that being provided with between the adjacent quirk wall special form brick on the same horizontal plane the upright brickwork joint of broken line shape, the brickwork joint of neighbouring quirk wall special form brick is provided with high-temperature agglomerant.

Described quirk wall special form brick top and bottom are respectively equipped with rim of the mouth and female mouth.

The upright brickwork joint of described broken line shape has consistent incline direction on quirk wall plane, this direction is consistent with the airflow direction of flue gas in the quirk.

The upright brickwork joint of described broken line shape is made up of two end seams and a middle part seam.

The direction of described end seam is perpendicular to quirk wall surface.

The direction of described middle part seam then is the α angle with quirk wall surface, and the scope of α angle is 0.5～90 degree.

Described high-temperature agglomerant is the high temperature clay.

The utlity model has following advantage:

1, the quirk special form brick that has adopted two ends to have broken line shape end face is built the quirk wall by laying bricks or stones, can form the upright seam of broken line shape laid dry as the fugitive constituent passage on each layer brick masonary.

2, the broken line shape fugitive constituent passage of being made up of the upright seam of numerous broken line shape laid dry can stop and fill the burnt quirk burning that sucked in a large number, effectively reduces and fills burnt scaling loss consumption.

3, can effectively keep the hopper top to fill the thickness of the bed of material, prevent that fresh air from entering hopper and the antianode goods produce oxidation, improve anode goods yield rate.

4, can reduce the anode goods oxidation that produces in the cooling procedure to enter the air generation retardation of hopper in the cooling furnace chamber by quirk.

5, in case take place because the overshoot of quirk wall special form brick error causes the upright brickwork joint width of laid dry to exceed standard, can do the trace swing to the quirk special form brick when building by laying bricks or stones, reach the purpose of limited adjustment, effectively solve the difficulty of building construction.

6, simple in structure, easy to implement.
