Abstract
The invention relates to the field of dry quenching device, in particular to a dry quenching furnace using an air cooling slant flue technique. The furnace comprises a cooling chamber, a slant flue, an annular air flue and a storage chamber, wherein a cooling device is arranged on the interior of a separating wall of the slant flue and a fireproofing tile is arranged on the exterior thereof. The cooling device has a metallic structure, wherein a snakelike air flue is arranged in the cooling device; the snakelike air flue is connected with an exterior air pipeline; a tile supporting board is arranged on the upper end of the cooling device; and the fireproofing materials on the upper and lower part of the tile supporting board are divided into two parts. The furnace of the invention has the advantages that the structure can prolong the use life of the separating wall of the slant flue, simplify the maintaining method of the slant flue of the dry quenching furnace, shorten the maintaining period and decrease the investment of a guiding air and cooling air backflow system.
Description
Technical field
The present invention relates to the dry coke quenching auxiliary field, particularly a kind of dry stove that puts out that adopts air cooling slant flue technique.
Background technology
In prior art, the dry partition wall put out between the oblique flue of stove is the structure of encorbelmenting to the Gan Xilu center, and the chute partition wall is all firebrick structure, and the weight of chute partition wall top refractory brick and the downward frictional force of coke, all focus on the chute partition wall; In addition, because the chute partition wall will expand or shrink when being subject to cold and hot variation.Due to above two reasons, the chute partition wall easily cracks, ruptures when normal production operation, at dry repair time that stove do not reach regulation shutdown maintenance of just having to that puts out, greatly reduces dry work-ing life of putting out stove.In addition, in prior art, the dry stove that puts out generally adopts by peephole and imports air and reflux gas to annular passage, and this just need to arrange two and overlap independently tubing system, and the pipeline of reflux gas is long, invests accordingly many.
Summary of the invention
The object of the present invention is to provide a kind of dry stove that puts out that adopts air cooling slant flue technique, this technology can extend dry work-ing life of putting out stove chute partition wall, simplify the dry method for maintaining that puts out stove chute partition wall simultaneously, shortened maintenance cycle, reduced the investment of air importing and cooling gas return-flow system.
For achieving the above object, the present invention realizes by following technical scheme:
A kind of dry stove that puts out that adopts air cooling slant flue technique, comprise cooling room, oblique flue, annular passage, the chamber that prestores, and it is characterized in that, tiltedly mid-feather inside is refrigerating unit, and outside is refractory brick.
Described refrigerating unit adopts metal construction.
Be provided with snakelike gas passage in described refrigerating unit, snakelike gas passage is connected with outside gas pipeline by arm.
Described arm is provided with the air volume regulating valve door.
Described refrigerating unit is provided with thermometer hole.
Described refrigerating unit top is provided with brick plate, and the refractory materials of brick plate upper and lower part is divided into to two parts.
Compared with prior art, advantage of the present invention is:
1) because tiltedly the inner employing of mid-feather refrigerating unit, outside adopt the structure of refractory brick, and be provided with snakelike gas passage and carry out air cooling in refrigerating unit, the heat of refrigerating unit is passed in absorption by coke, thereby refrigerating unit is shielded, and prevention damages because excess Temperature causes refrigerating unit;
2) owing to being provided with brick plate, make the refractory materials of brick plate upper and lower part be divided into two parts, thereby make the expansion of part refractory brick not affect bottom refractory brick, make upper and lower two portions refractory materials be divided into two integral body, prevented that upper and lower two portions refractory brick from making the drawing crack of chute partition wall because swell increment is inconsistent;
3) this structure can extend dry work-ing life of putting out stove chute partition wall, has simplified the dry method for maintaining that puts out stove chute partition wall simultaneously, has shortened maintenance cycle, has reduced the investment of air importing and cooling gas return-flow system.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of refrigerating unit;
Fig. 3 is the structural representation of oblique mid-feather.
Embodiment
See Fig. 1, a kind of dry stove that puts out that adopts air cooling slant flue technique, comprise cooling room 1, oblique flue 4, annular passage 3, the chamber 2 that prestores, peephole 6, and tiltedly mid-feather 13 inside are refrigerating unit 5, and outside is refractory brick, and refrigerating unit 5 adopts metal constructions.
See Fig. 2, be provided with snakelike gas passage 13 in refrigerating unit 5, snakelike gas passage 13 is connected with outside gas pipeline 8 by arm 7; Arm 7 is provided with air volume regulating valve door 9.Refrigerating unit 5 tops are provided with thermometer hole 10.
Refrigerating unit 5 tops are provided with brick plate 11, and the refractory materials of brick plate 11 upper and lower parts is divided into to two parts.
The working process of this device is: air and reflux gas enter arm 7 from pipeline 8; enter again refrigerating unit 5; enter annular passage 3 by communicating aperture 12 again; air and reflux gas are snakelike and flow in refrigerating unit 5; the heat of refrigerating unit 5 is passed in absorption by coke; thereby refrigerating unit is shielded, prevent to cause because of excess Temperature the damage of refrigerating unit.Be provided with thermometer hole 10 on the top of refrigerating unit 5, by the valve 9 of regulating on arm 7, control the temperature of refrigerating unit 5 in safety range.Be provided with brick plate 11 on refrigerating unit 5 tops, the weight of top refractory brick and the coke reactive force downward to refractory brick is distributed on each refrigerating unit 5 by brick plate 11, in addition owing to being provided with brick plate 11, the refractory materials that makes brick plate 11 upper and lower parts is divided into to two parts, thereby make the expansion of part refractory brick not affect bottom refractory brick, make upper and lower two portions refractory materials be divided into two integral body, prevented that upper and lower two portions refractory brick from making oblique mid-feather 13 drawing cracks because swell increment is inconsistent.
