Abstract
The utility model discloses a kind of high-altitude cast house workshop smoke evacuation building structures, the workshop sets at blast furnace iron notch and covers including tapping hole, slag iron ditch and cast house platform, the cast house platform is arranged on workshop bottom, iron mouth and slag iron ditch are arranged on cast house platform, it is corresponded in the workshop and dust excluding hood is equipped with above the position of iron mouth and slag iron ditch, the workshop is the workshop that binds, its roof setting smoke evacuation building, the smoke evacuation building is top seal, the chimney structure of lateral opening, and the workshop side wall bottom sets suspended hood.Advantage is：This structure utilizes " chimney effectiveness " natural dedusting, and remaining secondary smoke is made to be discharged by roofing quickly and orderly, reaches ideal dust removal by ventilation and heat dissipation effect.The process generates negative pressure without using extra power, while also avoids wild wind and be directly blown into cast house influence primary dedusting, and volume of smoke is caused to escape, pollutes environment.
Description
Technical field
The utility model is related to ironmaking technology field more particularly to a kind of high-altitude cast house workshop smoke evacuation building structures.
Background technology
Blast furnace cast house is mostly using semi-enclosed structure, and 1.5~2.5m height regions are opened wide on cast house platform, with
Achieve the purpose that aeration-cooling and smoke evacuation.In addition also there is the mill construction using totally-enclosed roof negative pressure ventilation and dust removal form.
Cast house is to tap a blast furnace and the operating area of slag sluicing system, and fume amount is big, such as uses semiclosed mill construction, wild wind can
Workshop directly is blown into, iron mouth and hot-metal bottle position dust excluding hood negative pressure exhausting is influenced, volume of smoke is caused to escape, generates a large amount of secondary fumes
Dirt.Using totally enclosed type mill construction, the construction roof negative pressure is small, and air quantity is small, and ventilation and heat speed is slow, and environment is disliked in workshop
It is bad, seldom use.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide one kind and external wild wind is avoided to be blown into, and makes flue dust in workshop
The high-altitude cast house workshop smoke evacuation building structure of quickly and orderly discharge.
Technical solution：The high-altitude cast house workshop smoke evacuation building structure of the utility model, the workshop is at blast furnace iron notch
Set and cover including tapping hole, slag iron ditch and cast house platform, the cast house platform is arranged on workshop bottom, iron mouth and
Slag iron ditch is arranged on cast house platform, is corresponded in the workshop and dust excluding hood is equipped with above the position of iron mouth and slag iron ditch, is used
In carrying out primary dedusting to the generated flue dust that taps a blast furnace, the workshop is the workshop that binds, and roof sets smoke evacuation building, the smoke evacuation
Building is top seal, the chimney structure of lateral opening.The workshop side wall bottom sets suspended hood.Wild wind on the outside of workshop
Enter from suspended hood so that workshop outfield wind directly can not be blown into workshop from top, blown out by smoke evacuation building, be formed in workshop
The air-flow of sequence is orderly blown out the flue dust that dust excluding hood is omitted by smoke evacuation building.
Further, since the workshop is in higher position, workshop side wall air quantity is very big, in order to avoid wild wind is directly from side
Face blows into the primary dedusting for influencing dust excluding hood, the situation that volume of smoke is caused to escape, so suspended hood is designed to top and factory
Room wall connecting, to the open structure of wall outer side, the wild wind made is blown into workshop from lower to upper from suspended hood bottom for bottom, cooperation
The smoke evacuation building of chimney structure so that indoor flue dust is orderly quickly discharged in workshop, reaches ideal dust removal by ventilation and heat dissipation effect
Fruit.
Wherein, bottom is less than the upper plane of cast house platform during the suspended hood setting, and is laid in workshop surrounding.Together
When the smoke evacuation building is set on to the center on workshop roof so that wild wind is formed in workshop by the circumferential direction roof of workshop bottom four
The airflow direction that center is gathered.
Setting ribbon skylight on the outside of the suspended hood so that suspended hood has both the effect of window simultaneously.
Advantageous effect：Compared with prior art, it is the advantages of the utility model：This structure utilizes " chimney effectiveness " to remove naturally
Dirt makes remaining secondary smoke be discharged by roofing quickly and orderly, reaches ideal dust removal by ventilation and heat dissipation effect.The process does not use
Extra power generates negative pressure, while also avoids wild wind and be directly blown into cast house influence primary dedusting, and volume of smoke is caused to escape,
Pollute environment.

Fig. 2 is the utility model workshop internal gas flow flow direction schematic diagram；
Fig. 3 is Figure 1A-A sectional views.
Specific embodiment
The technical solution of utility model is described further below in conjunction with the accompanying drawings.
High-altitude cast house workshop smoke evacuation building structure as shown in Figure 1, the workshop 1 set and are covered at blast furnace iron notch 2
Lid includes tapping hole 2, slag iron ditch 3 and cast house platform 4, and the cast house platform 4 is arranged on 1 bottom of workshop, and iron mouth 2 is set
In one end of slag iron ditch 3, slag iron ditch 3 corresponds to iron mouth 2 and slag iron ditch on the center line of cast house platform 4 in the workshop 1
Dust excluding hood 5 is equipped with above 3 position, and is connected to outside workshop.
The workshop is the workshop that binds, and roof setting smoke evacuation building 6, the smoke evacuation building 6 is top seal, lateral opening
Chimney structure, meanwhile, the smoke evacuation building 6 is set on the center on 1 roof of workshop.
The 1 side wall bottom of workshop is in the absolute altitude suspended hood 7 arranged below of cast house platform 4, that is, air draught when setting
Cover the upper plane that 7 bottoms are less than cast house platform 4.Wherein, the top of the suspended hood 7 and 1 wall connecting of workshop, bottom to
Wall outer side is opened wide, and forms the window construction that similar lower part is opened from inside to outside.
As shown in Fig. 2, primary dedusting, workshop are carried out by the suspended hood 7 of top close to the flue dust of iron mouth 2 and slag iron ditch 3
Outside open country wind is blown into from the lower part of suspended hood 7 in workshop, then is blown out by smoke evacuation building 6 so that wild wind is formed in workshop by workshop
The airflow direction that the circumferential roof in bottom four center is gathered.
As shown in figure 3, the suspended hood 7 is laid in 1 circumferentially-spaced of workshop.
In view of the daylighting in workshop, in the 7 outside setting ribbon skylight of suspended hood.
