Abstract
This utility model is related to a kind of electric furnace arrangement for producing steel row dust-removing device, including being arranged on the outside joint sealing (2) of electric arc furnace (1), the exhaust fume collecting hood (3) for being arranged on joint sealing (2) upper end and landing chimney (5), exhaust fume collecting hood (3) is by smoke uptake (4) connection landing chimney (5).Exhaust opening (7) is offered above electric arc furnace (1).Exhaust fume collecting hood (3) is connected with smoke uptake (4) by the sleeve pipe (8) at top.Electric furnace arrangement for producing steel row's dust-removing device that this utility model is provided employs exhaust fume collecting hood, ensure that the effectively smoke evacuation of whole smelting process does not affect to smelt work, operative will not be impacted, and the setting for landing chimney ensure that flue-gas temperature is low, without the concern for cooling problem, cost, whole device simple structure, saving fund, easy to manufacture and management are saved.
Description
Technical field
This utility model is related to a kind of integral system for excluding flue dust for electric arc furnace in steel smelting procedure, especially relates to
And a kind of electric furnace arrangement for producing steel arranges dust-removing device, belongs to field of iron and steel smelting.
Background technology
In steel smelting procedure, Dedusting of EAF is due to flue-gas temperature height, technological requirement is high and equipment is complicated, so removing
Dirt device is relatively difficult to design.Usually, the cleaner of less than 25 tons of middle-size and small-size electric arc furnace mainly includes interior smoke evacuation and outer
Smoke evacuation two types.The mode of interior row can cause flue gas to enter the iron and steel of molten condition, form impurity, bubble, affect iron and steel
Quality, especially special steel, have very high requirement in terms of the attributes such as intensity, toughness and section.Therefore, traditional whether
The mode of interior smoke evacuation or outer smoke evacuation is all unable to the actual problem of effectively solving.
Utility model content
In order to overcome the deficiencies in the prior art, problem of the prior art is resolved, make up existing existing in the market product
The deficiency of product.
This utility model provide a kind of electric furnace arrangement for producing steel arrange dust-removing device include being arranged on joint sealing outside electric arc furnace,
The exhaust fume collecting hood and landing chimney of joint sealing upper end is arranged on, exhaust fume collecting hood is by smoke uptake connection landing chimney.
Preferably, exhaust opening is offered above above-mentioned electric arc furnace.
Preferably, above-mentioned exhaust fume collecting hood is connected with smoke uptake by the sleeve pipe at top.
Preferably, electric arc furnace is erected at the inside of joint sealing by being erected at the fixed support at top, and fixed support is fixed on
Top outside joint sealing.
Preferably, above-mentioned exhaust fume collecting hood inwall scribbles Plumbum preparatium and paint.
Electric furnace arrangement for producing steel row's dust-removing device that this utility model is provided employs exhaust fume collecting hood, it is ensured that whole smelting process
Effectively smoke evacuation does not affect to smelt work, and operative will not be impacted, and the setting for landing chimney ensure that flue-gas temperature
Low, it is not necessary to consider cooling problem, save cost, whole device simple structure, saving fund, easy to manufacture and management.
Description of the drawings
Fig. 1 is this utility model structural representation.
Reference：1- electric arc furnace；2- joint sealings；3- exhaust fume collecting hoods；4- smoke uptakes；5- lands chimney；6- fixed supports；7- is arranged
Mouth；8- sleeve pipes.
Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement this utility model, below in conjunction with the accompanying drawings and be embodied as
Mode is described in further detail to this utility model.
The present embodiment as shown in figure 1, electric furnace arrangement for producing steel row dust-removing device, including the joint sealing being arranged on outside electric arc furnace 1
2nd, the exhaust fume collecting hood 3 and landing chimney 5 of joint sealing 2 upper end are arranged on.Exhaust fume collecting hood 3 is by the connection landing chimney 5 of smoke uptake 4.Collection cigarette
Cover 3 inwalls and scribble Plumbum preparatium and paint, it is ensured that be less likely to occur to corrode under high temperature, and then the life-span of extension device.
The top of electric arc furnace 1 offers exhaust opening 7.Exhaust fume collecting hood 3 is connected with smoke uptake 4 by the sleeve pipe 8 at top.Electric arc furnace
1 inside for being erected at joint sealing 2 by being erected at the fixed support 6 at top, fixed support 6 are fixed on top outside joint sealing 2.
Operationally, flue gas enters exhaust fume collecting hood 3 by the exhaust opening 7 of 1 upper end of electric arc furnace, carries out preliminary in exhaust fume collecting hood 3
Cooling enters landing chimney 5 by smoke uptake 4 again.Smoke uptake 4 is general to arrange longer length, can be further right in outdoor
Flue gas is cooled down, and when discharging finally by landing chimney 5, solid-state smoke particle has been precipitated, and only harmless gas is discharged.Both
Environment is protected to also achieve the effect for excluding flue dust.
Electric furnace arrangement for producing steel row's dust-removing device that this utility model is provided employs exhaust fume collecting hood, it is ensured that whole smelting process
Effectively smoke evacuation does not affect to smelt work, and operative will not be impacted, and the setting for landing chimney ensure that flue-gas temperature
Low, it is not necessary to consider cooling problem, save cost, whole device simple structure, saving fund, easy to manufacture and management.
The specific embodiment of the above is better embodiment of the present utility model, not limits this practicality with this new
Type is embodied as scope, and scope of the present utility model includes being not limited to this specific embodiment, all according to this utility model
Shape, the equivalence changes made of structure are in protection domain of the present utility model.
