Abstract
The utility model provides a secondary fume-collecting hood for an electric furnace. The utility model resolves the problems of the prior collecting hood, such as heaviness and high resistance. The secondary fume-collecting hood comprises a collecting hood with collecting orifices. The technical points of the secondary fume-collecting hood are as follows: a large hood which is combined with a roof is adopted as the collecting hood, at least two collecting pipes are fixed by suspension brackets in a skirt formed by color plates arranged on the circumference of the large hood of the roof, and the collecting pipes which are respectively provided with the primary collecting orifices and the secondary collecting orifices are communicated with the same collecting main. The collecting hood, which has the advantages of reasonable structure design, light weight, convenient construction, low resistance and the like, is favorable for the fast flow of fume and can notably improve the collecting effect.
Description
Technical field
The utility model relates to a kind of electric furnace flue gas controlling device, particularly a kind of electric furnace secondary cigarette fume trap cover.The electric furnace flue gas that is mainly used in industries such as HVAC, dedusting, metallurgy captures to be administered.
Background technology
At present, the steel mill electric furnace of metallurgy industry is when reinforced and tapping, because under the high-temperature operation condition, excessive flue gas can give out a large amount of dust and considerable heat, causes operating personnel's working environment very severe, natural environment suffers severe contamination.Electric furnace secondary cigarette capture form in the past mainly contains umbrella hood, differential fume trap cover and overhead traveling crane through type fume trap cover, and these three kinds of covers all have only one to capture mouth, although it has certain capture effect, the shortcoming that the weight that exists fume trap cover is big, resistance is high.
The utility model content
The purpose of this utility model provides a kind of electric furnace secondary cigarette fume trap cover, and problems such as the weight that it has solved existing fume trap cover existence is big, resistance height have reasonable in design, in light weight, be convenient to construction, resistance is little, help flowing rapidly of flue gas, significantly improve advantages such as capturing effect.
The technical scheme that the utility model adopted is: this electric furnace secondary cigarette fume trap cover comprises the fume trap cover that has the capture mouth, its technical essential is: described fume trap cover adopts the big cover that combines with the roof, the big cover in roof is all around to fix at least two capture conduits by suspension bracket in the shirt rim of colored steel shutoff one-tenth, and the described capture conduit that is respectively arranged with one-level capture mouth and secondary capture mouth communicates with same capture house steward.
Between described capture conduit and the described capture house steward expansion loop is set.
Advantage and the good effect that the utlity model has are: because this fume trap cover adopts the big cover that combines with the roof, the big cover in this roof is being set directly over electric furnace, the excessive flue gas that electric furnace is produced rises and enters the big cover in roof that has the shirt rim all around, capture mouth via one-level capture mouth and secondary and enter the capture conduit respectively, import again and capture house steward, so problems such as the weight that it has solved existing fume trap cover existence is big, resistance height.Compare with the existing single fume trap cover that captures mouth, adopt this a plurality of fume trap covers that capture mouth that have, utilize a plurality of wind speed that capture mouth will be lower than the single advantage that captures mouth, make its structure design more reasonable, thereby it is in light weight to reach fume trap cover, is convenient to construction, captures the little purpose of resistance of mouth, more help flowing rapidly of flue gas, significantly improve the capture effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Sequence number explanation among the figure: 1 capture house steward, 2 capture conduits, 3 secondarys capture mouth, 4 one-levels capture mouth, the big cover in 5 roofs, 6 suspension brackets, 7 supports, 8 electric furnaces, 9 roofs, 10 expansion loops
The specific embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1～2.This electric furnace secondary cigarette fume trap cover comprise have one-level capture mouthfuls 4 and secondary capture mouthfuls 3 fume trap cover and capture conduit 2 and capture parts such as house steward 1.Wherein fume trap cover is according to the specification of factory building and the needs of use, adopt the big hood configuration that combines with roof 9, in the shirt rim that becomes with the colored steel shutoff around the big cover 5 in roof, the shirt rim should be as far as possible to test, not influence overhead traveling crane by being advisable when big cover 5 shirt rims, roof are set.Owing to can adopt the steel work and the colored steel of optimization, can make the weight of whole fume trap cover want light with respect to traditional fume trap cover.
By suspension bracket 6 fixing at least two capture conduits 2, present embodiment is provided with three capture conduits 2.For ease of flowing rapidly of flue gas, can utilize a plurality of wind speed that capture mouthful will be lower than the single advantage that captures mouthful, each capture conduit 2. be provided with respectively one-level capture mouthfuls 4 and secondary capture mouthfuls 3, each is captured conduit 2 and same capture house steward 1 communicates after fixedly connected.Capturing house steward 1 directly is fixed together by support 7 and factory building.Consider the influence of variations in temperature, between capture conduit 2 and capture house steward 1, expansion loop 10 can also be set, the influence that the stress effect that is produced with expanding with heat and contract with cold of elimination pipeline brings the material expansion performance.
The flue gas that electric furnace 8 is produced in reinforced, smelting, tapping process is excessive, under the effect of high temp jet, rise in the shirt rim of the big cover 5 in roof, in the big cover 5 in roof, capture mouth 3 and one-level capture mouth 4 by secondary respectively, the flue gas that enters the big cover 5 in roof is led away rapidly, to significantly improve the capture effect.Simultaneously, can also on the support 7 in electric furnace shop and continuous casting workshop, the isolation barricade be set, to prevent the interference of beam wind.
Claims (2)
1, a kind of electric furnace secondary cigarette fume trap cover, comprise and have the fume trap cover that captures mouth, it is characterized in that: described fume trap cover adopts the big cover that combines with the roof, the big cover in roof is all around to fix at least two capture conduits by suspension bracket in the shirt rim of colored steel shutoff one-tenth, and the described capture conduit that is respectively arranged with one-level capture mouth and secondary capture mouth communicates with same capture house steward.
2, electric furnace secondary cigarette fume trap cover according to claim 1 is characterized in that: between described capture conduit and the described capture house steward expansion loop is set.
