Abstract
The utility model discloses a dust suction hood with an air curtain in cast house of iron making furnace. The hood is installed in the upper part of a taphole of the furnace and an iron runner connecting to the taphole. The hood comprises an air blast and an air draft hood connecting to a dust suction pipe of the dust cleaning apparatus. It is characterized in that a blast channel with air downrun is installed around the lower edge of the air draft hood; air deflectors are arranged in the blast channel evenly; the blast channel connects to the air blast via a tuyere pipe. The utility model is of reasonable structure, novel design. The dust suction rate can reach up to more than 95%. With the advantages, the pollution in front of furnace is reduced, thus the environmental quality is improved considerably. The utility model is spread and applied in dust suction in iron making furnace.
Description
Affiliated technical field
The utility model relates to iron-smelting blast furnace dust suction dedusting technology field, specifically a kind of suction device of the trough top that is installed in the iron-smelting blast furnace iron notch and is connected with iron notch.
Background technology
At present, most iron-smelting blast furnace, its dust hood generally all be arranged on the iron-smelting blast furnace casting house above.The suction device of this traditional structure, advantage are directly near the flue dust the trough to be delivered to and carry out dedusting in the cleaning apparatus.But in flushing and casting, this suction device will leave certain height in the ordinary course of things for the ease of the workman.Because position that suction device is installed and the distance between the casting house ground are than higher, add near the influence that is easy to be subjected to other air-flows iron notch and the trough, therefore there is quite a few cigarette ash dust to fly to the space to external diffusion, influenced pick-up performance, influence the blast furnace work quality, the contaminate environment health.
Summary of the invention
In order to overcome the deficiency that existing iron-smelting blast furnace suction device structurally exists, the utility model provides a kind of iron-smelting blast furnace casting house dust hood of simple in structure, band air curtain that pick-up performance is good.
The technical scheme that its technical problem that solves the utility model adopts is: the iron-smelting blast furnace casting house dust hood of this band air curtain, the trough top that is installed in the iron-smelting blast furnace iron notch and is connected with iron notch, it comprises gas blower and the draught hood that is connected with the sweep-up pipe of cleaning apparatus, mainly be said draught hood around the lower edge be provided with breezeway to katabatic wind, be provided with air deflector in the breezeway equably, the coupling end of breezeway connects gas blower by airduct; The bottom of said gas blower is provided with fixed support or mount pad.
The utility model compared with prior art, topmost advantage is rational in infrastructure, modern design, dust suction with gather dust effective.Because the lower edge is provided with the breezeway to katabatic wind around draught hood, is provided with air deflector in the breezeway equably, the coupling end of breezeway is connected with gas blower by airduct.After the cigarette ash dust comes out from iron notch, on the one hand, be not able to do in time in diffusion all around, just dust is covered firmly by the downward air curtain that forms around the draught hood.On the other hand, the powerful suction that draught hood produces is the whole inspirations of dust that produce, and delivers to and carry out purifying treatment in the cleaning apparatus.Facts have proved, the dust suction dust arrester installation of this blast furnace, dust-absorbing rate can reach more than 95%, has reduced the environmental pollution of stokehold, has improved the environmental quality of blast furnace periphery greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
1. iron-smelting blast furnaces among the figure, 2. iron notch, 3. airduct, 4. gas blower, 5. trough, 6. draught hood, 7. breezeway, 8. air deflector, 9. mount pad, 10. sweep-up pipe, 11. coupling ends.
Embodiment
As shown in Figure 1, the iron-smelting blast furnace casting house dust hood of this band air curtain, trough 5 tops that are installed in iron-smelting blast furnace 1 iron notch 2 and are connected with iron notch 2, it comprises gas blower 4 and the draught hood 6 that is connected with the sweep-up pipe 10 of cleaning apparatus, mainly be said draught hood 6 around the lower edge be provided with breezeway 7 to katabatic wind, be provided with air deflector 8 in the breezeway 7 equably, the coupling end 11 of breezeway 7 connects gas blower 4 by airduct 3, and the bottom of gas blower 4 fixes gas blower 4 on the ground firmly by mount pad 9.
Claims (2)
