Abstract
The utility model discloses a blast furnace tap-hole dust collecting housing with a gas curtain device, which comprises a housing body, a gas curtain device and a high-pressure blower; the gas curtain device is formed by a wind pipe which is fixed on the bottom part on the periphery of a housing body mouth and is provided with a bar-shaped opening, and the wind pipe is connected with the high-pressure blower through a connecting pipe. The wind pipe with the bottom part having the bar-shaped opening is arranged on the periphery of the blast furnace tap-hole dust collecting housing mouth, and the wind pipe is connected with the high-pressure blower, so when a blast furnace discharges iron, the high-pressure blower is started to form a downward gas curtain, so an effect on separating a dust area below the dust collecting housing from the external air can be played, a negative pressure area of the dust collecting housing for absorbing the dust can be increased, and the dust collecting rate of the tap-hole can be improved.
Description
Technical field
The utility model relates to a kind of cleaning apparatus, especially a kind of blast furnace iron notch dust excluding hood that has air curtain device.
Background technology
The flue dust that iron notch produces during blast furnace ironmaking is the main dust production resource of blast furnace discharge yard.Characteristics such as the flue gas that iron notch sprays has the temperature height, jet power is strong, emitted dose is big, the flue dust particle size range is wide.The iron notch flue gas is spurting and penetrates and the diffusion of rising rapidly from iron notch under the effect of hot pressing and furnace pressure, spread in the whole casting house.The iron-smelting process equipment such as taphole stopping machine, clay gun of opening are set in the blast furnace iron notch both sides usually, and under the condition that does not influence out stifled iron notch operation and cleaning iron notch, the layout of iron notch smoke catching cover will be subjected to the spatial restriction.The design of blast-furnace tuyere platform is at present only considered arts demand and is not considered dust separating needs, the smoke catching cover can only be in the nearer area arrangements of distance iron notch, generally speaking, the smoke catching cover is installed in the position of casting house platform more than 2 meters, capture rate to flue dust reduces rapidly with the increase of mounting height, when casting house had side direction wind or iron notch splash to occur, the high pressure flue gas can be gone out the smoke catching district, very easily caused the generation of flue dust out-of-control phenomenon.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, blast furnace iron notch dust excluding hood that has air curtain device with higher dust arrestment rate.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of blast furnace iron notch dust excluding hood that has air curtain device comprises cover body, air curtain device and high pressure positive blower; Described air curtain device is made of the airduct that the bottom that is fixed on cover body cover mouth periphery has opening, and airduct is connected with high pressure positive blower by pipe connecting.
Adopt the beneficial effect that technique scheme produced to be: the utility model is provided with the airduct of bottom opening at blast furnace iron notch dust excluding hood cover mouth periphery, and it is connected with high pressure positive blower, during blast furnace casting, start high pressure positive blower and form downward air curtain, play the effect of isolating dust excluding hood flue dust district, below and extraneous air, can increase dust excluding hood and inhale the negative pressuren zone of catching flue dust, improve the dust arrestment rate of iron notch.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Wherein, 1, cover body, 2, airduct, 3, high pressure positive blower, 4, pipe connecting, 5, blast furnace.
Embodiment
As shown in Figure 1 and Figure 2, a kind of blast furnace iron notch dust excluding hood that has air curtain device comprises cover body 1, air curtain device and high pressure positive blower 3; Described air curtain device is made of the airduct 2 that the bottom that is fixed on cover body 1 cover mouthful periphery has opening, and airduct 2 is connected with high pressure positive blower 3 by pipe connecting 4.
Dust excluding hood is installed in the iron notch top of blast furnace 5, because the stokehold processing unit need be installed in ground near the iron notch, the personnel activity is more, the mounting height of dust excluding hood is a principle not influence stokehold processing unit operation and blast-furnace man's work, reduce mounting height as far as possible, airduct 2 is installed on three relative peripheries of iron notch.
During blast furnace casting, start high pressure positive blower 3, high-pressure blast forms downward air curtain by airduct 2, play the effect of isolating dust excluding hood flue dust district, below and extraneous air, can increase dust excluding hood and inhale the negative pressuren zone of catching flue dust, stopped by air curtain after the flue dust of iron notch ejection runs into air curtain, improved the dust arrestment rate of iron notch.
Claims (2)
1. a blast furnace iron notch dust excluding hood that has air curtain device comprises cover body (1), it is characterized in that also comprising air curtain device and high pressure positive blower (3); Described air curtain device is made of the airduct (2) that the bottom that is fixed on cover body (1) cover mouthful periphery has strip gab, and airduct (2) is connected with high pressure positive blower (3) by pipe connecting (4).
2. a kind of blast furnace iron notch dust excluding hood that has air curtain device according to claim 1 is characterized in that: described airduct (2) is positioned on three relative peripheries of iron notch.
