Abstract
The invention discloses a dust hood for a blast furnace tap hole. The dust hood for the blast furnace tap hole comprises a top-suction dust hood and a side-suction dust hood, wherein the top-suction dust hood is arranged above the outer side of the blast furnace tap hole, and the side-suction dust hood is arranged at one side of a molten iron trough, which is connected with the blast furnace tap hole; the top-suction dust hood comprises a first dust removal pipe and a first dust hood connected with the first dust removal pipe; the side-suction dust hood comprises a second dust removal pipe and a second dust hood connected with the second dust removal pipe; and the hood mouth of the side-suction dust hood is inclined. According to the dust hood for the blast furnace tap hole, the energy consumption can be reduced, the working environment of a casting house is improved and the smoke dust collection efficiency can be increased.
Description
Technical field
The present invention relates to a kind of blast furnace discharge yard environmental dust removal device, particularly a kind of blast furnace iron notch dust excluding hood.
Background technology
The casting house smoke contamination is serious, and every generation 1t iron produces the 2.5kg flue dust approximately.Iron notch is the main flue dust source of emission in the casting house, accounts for 30% of gross contamination thing, carries out effective dedusting of iron notch, to improving working conditions before the State of Blast Furnace, reduces flue dust atmospheric pollution is played an important role.The flue gas trapping of blast furnace iron notch adopts side draught or side draught to add the mode that the top suction combines more.The Tie Kou both sides are provided with side sucking hood, for guaranteeing that the high-temperature flue gas that rises also can obtain capturing, generally side sucking hood are designed to high-order side sucking hood at present, and for effectively taking away flue gas, also needing suitably increases the exhausting amount, not only sucks too much air, has also increased energy consumption simultaneously.And for inhaling cover in the top, for protecting the normal use of iron perforater and clay gun, it is generally bigger apart from the distance of iron notch flue dust that cover is inhaled on the top, makes flue dust in uphill process, spread escape, is difficult to capture fully.
Summary of the invention
Technical problem to be solved by this invention is to the deficiency of above-mentioned prior art existence a kind of blast furnace iron notch dust excluding hood that can improve smoke catching efficient to be provided.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be: a kind of blast furnace iron notch dust excluding hood; It comprises top absorption dust hood and side draught dust excluding hood; Wherein the top that dust hood is installed in the blast furnace iron notch outside is absorbed on the top, and the side draught dust excluding hood is installed in a side of the trough that is connected with blast furnace iron notch; The top is absorbed dust hood and is comprised first dust removing tube and first dust excluding hood that is connected with dust removing tube; The side draught dust excluding hood comprises second dust removing tube and second dust excluding hood that is connected with second dust removing tube, and the cover mouth of side draught dust excluding hood is for being obliquely installed.
By technique scheme, the angle of inclination of the cover mouth of described side draught dust excluding hood is 30 °～60 °.
By technique scheme, the cover mouth that dust hood is absorbed on described top is provided with the first movable dedusting baffle plate, and the cover mouth of side draught dust excluding hood is provided with the second movable dedusting baffle plate.
By technique scheme, the described first movable dedusting baffle plate, the second movable dedusting baffle plate are the baffle plate or the baffle plate for interlocking up and down of venetian blind type.
Beneficial effect of the present invention is:
1, the cover mouth of side draught dust excluding hood is set to the cover mouth, shortens flue dust to cover mouthful stroke on the one hand, can effectively improve the iron notch efficiency of dust collection; The flue dust that makes rising on the other hand is when running into the cover mouth of inclination, and the rising of flue dust is suppressed and rests on original place or move downward, and is captured by side sucking hood more easily, has improved the collection efficiency of side draught dust excluding hood, cuts down the consumption of energy, and improves the casting house Working environment.The cover mouth of side draught dust excluding hood is set to the cover mouth, shortens the stroke that flue dust gets into side sucking hood, makes dust excluding hood suction opening place suction even, under identical exhausting amount, takes away more flue dust, improves efficiency of dust collection.
2, install movable baffle plate at the cover mouth of dust excluding hood, baffle plate evenly blower fan from the center to the limit air draft speed of portion, make in the dust excluding hood cover mouth plane draft even; The exhausting amount of blower fan all is utilized effectively; Reduce the suction of wild wind, simultaneously, the disturbance of whirlwind to the iron notch flue dust eliminated in the use of baffle plate; Flue dust is Methodistic to be taken away by dust excluding hood, has effectively improved efficiency of dust collection.
