Abstract
The utility model relates to a blast furnace roof water injection gun and belongs to the technical field of blast furnace cooling tools. The blast furnace roof water injection gun comprises a tubular gun body, wherein a water inlet is arranged at one exposed end of the gun body outside the blast furnace wall and connected with an external water supply pipe, the other end of the gun body is a blind end extending into the blast furnace wall, and a plurality of water discharge holes are formed on the upper half surface of the section close to the blind end of the gun body. The blast furnace roof water injection gun adopts the plurality of water discharge holes instead of the single water discharge hole of the prior art, so as to achieve the purpose of back-spraying a plurality of small water streams into the blast furnace instead of directly spraying a single water column into the blast furnace, therefore, the furnace top temperature is reduced uniformly and effectively, the detonation inside the furnace is eliminated, the falling of the brick lining of the furnace body is prevented and the requirement for safe and successful furnace shutdown is met.
Description
Technical field
The utility model relates to a kind of furnace roof that blast furnace stopping uses rifle of fetching water that is used for, and belongs to the blast furnace technical field of tools that cools.
Background technology
Water pipe of the general employing of the rifle of fetching water that the tradition blast furnace stopping uses, water enters after the direct ejection of the other end, to cooling in the blast furnace from water pipe one end.Because the water yield concentrates a place to be a water column ejection, and each regional injection flow rate in the blast furnace is distributed inequality, causes the weak effect that cools; And single water column shape water spray of concentrating is difficult to rapid vaporization, causes less water to fall into to be decomposed behind the high-temperature zone of bottom house and produces hydrogen, can cause after hydrogen has been assembled many to cause pinking in the stove shaft bricking to be caved in, and then lead to a disaster.
The utility model content
The technical problems to be solved in the utility model is, proposes a kind of injection flow rate distributed uniform, can reduce throat temperature uniformly and effectively, the blast furnace furnace roof of eliminating pinking in the stove rifle of fetching water.
The technical solution of the utility model is: a kind of blast furnace furnace roof rifle of fetching water, comprise tubulose rifle body, and described rifle body exposes the water-in that the outer end of blast furnace furnace wall is provided with external water supply line, and the other end of described rifle body is the cecum that stretches in the blast furnace furnace wall; Have a plurality of posticums on first surface of one section near the described rifle body cecum.
Blast furnace furnace roof of the present utility model is fetched water rifle in use, because posticum only is positioned on first surface of rifle body, the cold water of ejection is spray up earlier, under action of gravity, spill out downwards then, drench to stove just as " fountain " sample is counter, owing to be a plurality of posticums, can make the cold water of ejection more even simultaneously.Like this, compare the existing blast furnace furnace roof rifle of fetching water, the blast furnace furnace roof of the present utility model rifle of fetching water changes a plurality of posticums into by having one of the rifle of fetching water big water outlet now, a traditional water column is directly sprayed become many anti-the pouring in the stove of thread in the stove, thereby can reduce throat temperature uniformly and effectively, pinking in the elimination stove reduces shaft bricking slump, satisfies the needs of safety, smooth blowing out.
Improvement of the technical scheme is: the medullary ray between adjacent two of the described posticum intersects each other.Like this, can make many threads water spray produce atomizing in the collision back mutually, can accelerate rising effusion furnace roof after the water vapor, thereby be more conducive to cooling, and can eliminate water and fall into to decompose behind the blast furnace high-temperature zone and produce hydrogen the blast furnace furnace roof.
Further improvement in the technical proposal is: the aperture of described posticum is 1-3mm.Like this, can further improve the atomizing effect of water spray.
The further improvement of technique scheme is: described posticum away from the distance of end of cecum and blast furnace furnace wall more than or equal to 1000mm.Like this, can prevent that water projection from causing to the furnace wall the material of furnace wall to make moist and caving in after the infringement.
Further improving again of technique scheme is: described posticum is along the uniform in length and breadth row that are arranged as in rifle body first half surface, every discharge water hole along rifle body length direction uniformly at intervals, it is uniform along the same semicircumference on rifle body first half surface whenever to list the water hole.
Description of drawings
Be described further of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the fetch water structural representation of rifle of the utility model embodiment blast furnace furnace roof.
Fig. 2 is the A-A view in transverse section of rifle body among Fig. 1.
Fig. 3 is the vertical partial section of the B-B of rifle body among Fig. 1.
Embodiment
Embodiment
The blast furnace furnace roof of present embodiment is fetched water rifle as shown in Figure 1, comprises tubulose rifle body 1, and rifle body 1 exposes the water-in 3 that blast furnace furnace wall 2 outer ends are provided with external water supply line, and the other end of rifle body 1 is the cecum 4 that stretches in the blast furnace furnace wall 2.On near first surface of one section rifle body 1 cecum 4, have a plurality of posticums 5.Posticum 5 away from the distance of end of cecum 4 and blast furnace furnace wall more than or equal to 1000mm.Posticum 5 is along the uniform in length and breadth row that are arranged as in rifle body 1 first half surface.Every discharge water hole 5 along rifle body 1 length direction uniformly at intervals.
As Fig. 2, shown in Figure 3, it is uniform along the same semicircumference on rifle body first half surface whenever to list water hole 5, and the medullary ray between adjacent two posticums 5 of every row or every row intersects each other.The aperture of posticum 5 is 1-3mm.
When present embodiment blast furnace furnace roof is fetched water the rifle use, the cold water that enters from water-in 3 forms tiny vaporific current ejection from the uniform posticum 5 that is arranged as row, and the tiny vaporific current of per two adjacent posticums, 5 ejections are gone back intersection-type collision each other, further be atomized into fine liquid particles, thereby form the big and uniform water smoke of scope on blast furnace furnace roof top, this water smoke is under action of gravity, and the anti-pouring stove that falls is interior with the cooling blast furnace.Whereabouts water smoke absorbs in the blast furnace and is easy to be vaporized behind the heat, just rises behind the spray vaporization and takes away heat in the blast furnace from the Top of BF effusion, in this process, seldom has oarse-grained water droplet to fall into high-temperature zone, bottom in the blast furnace, therefore can not produce hydrogen.
The blast furnace furnace roof of the present utility model rifle of fetching water is not limited to the various embodiments described above, such as: 1) medullary ray between adjacent two posticums 5 also can mutually disjoint; 2) posticum 5 also can not uniformly be arranged as row; 3) every discharge water hole 5 also can be apart from differently at interval along rifle body 1 length direction; 4) whenever listing water hole 5 can be not uniform in same semicircumference yet; 5) aperture of posticum 5 also can be greater than 3mm; Or the like.All employings are equal to replaces the technical scheme that forms, and all drops on the protection domain of the utility model requirement.
