Description
Technical field
Blast furnace dedusting system equipment field is the utility model is related to, is inhaled more specifically to a kind of blast furnace iron notch top
Dust arrester.
Background technology
A kind of device that dust arrester belongs to cast house dust pelletizing system is inhaled on blast furnace discharge yard top, can pass through blast furnace discharge yard
Inhale one kind that dust arrester carries out instantaneous flue gas trapping in Horizontal open machine opening, pad sand and clay gun machine gun mudding botting in top
Dust arrester is inhaled on blast furnace discharge yard top, is widely used in the industries such as metallurgical, casting at present.
Blast furnace for configuring Horizontal open machine, it is neat by cover top and blast furnace tuyere platform that dust arrester is inhaled on cast house top
Flat, i.e. the mode of tapping hole strength smoke evacuation is taken in tapping hole dedusting, i.e., using the wide long feature of tuyere platform, to tapping hole region
Effectively sealed, top draft hood is set above the iron runner of tuyere platform end, and side-draught hood is set in iron runner both sides, carry out strength row
Cigarette, flue gas caused by tapping hole is trapped on the spot in tuyere platform region to greatest extent.Cast house dust pelletizing system is improved to remove
The operating efficiency of dirt.The industries such as metallurgical, casting are widely used at present.
But the blast furnace for configuring overhead tapping machine, (typically puts down because hydraulic pipeline apical side height is higher in frame compared with air port
Platform >=1.9m), cause cast house top to inhale dust arrester top surface absolute altitude lifting, influence the effective suction that dust arrester is inhaled on top, and wind
Be highly prone to above mouthful platform two cast house factory buildings and its between depletion region transverse direction wind effect, be commonly called as wild wind, cause worker
The work position cloud of dust diffuses, and has a strong impact on the physical and mental health of operating personnel, reduces labor productivity.Caused subject matter is such as
Under：
(1) dust arrester top surface absolute altitude lifting is inhaled on the top of cast house, is had a strong impact on that the suction of dust arrester is inhaled on top, is caused cigarette
Gas can not promptly and accurately enter top and inhale in dust arrester cover mouth, influence post health；
(2) dust arrester top surface absolute altitude lifting is inhaled on cast house top, accelerates horizontal wind effect, or even the Work places cloud of dust is more
It is unrestrained, it can not ensure that overhead tapping machine is promptly and accurately directed at tapping hole and is open and padded husky operation, influence to produce normal operation；
(3) dust arrester top surface absolute altitude lifting is inhaled on the top of cast house, accelerates horizontal wind effect, or even the Work places cloud of dust
Diffuse, can not ensure that stemming operating personnel is promptly and accurately lost in quasi- clay gun machine on tuyere platform, and then influence to carry out clay gun machine
The closure operation of stemming, influence to produce normal operation.It can cause loss serious simultaneously, increase production cost；
(4) clay gun machine and its during being supported on maintenance, inhales dust arrester (with trough direction by transverse crossing cast house top
Less parallel), when serious cast house top will be caused to inhale the possibility influence that dust arrester is scrapped, add the cost of overhaul.
Chinese patent application, application number 201220071236.0, publication date on November 14th, 2012, disclose a kind of blast furnace
Tapping hole dust excluding hood.It includes top and absorbs dust hood and side absorption dust hood, is installed in wherein dust hood is absorbed on top on the outside of blast furnace iron notch
Top, side absorbs dust hood and is installed in the side of the trough being connected with blast furnace iron notch；Absorb dust hood and removed including first in top
Dirt pipe and the first dust excluding hood being connected with dust removing tube；Dust hood is absorbed in side to be included the second dust removing tube and is connected with the second dust removing tube
The second dust excluding hood, the cover mouth of dust hood is absorbed to be obliquely installed in side.The use of such a dust hood for blast furnace tap hole not only reduces energy
Consumption, improve cast house working environment and smoke catching efficiency can be improved.But this dust excluding hood still influences to carry out clay gun machine gun mud
Closure operation, influence produce normal operation.
The content of the invention
1. technical problems to be solved
The cast house top suction dust arrester configured for existing blast furnace in Horizontal open machine technology traps in run at high level
Ability is weak, because of the problems such as horizontal wind effect escape phenomenon is serious, cast house operating environment difference, and the utility model provides a kind of height
Stove tapping hole top inhale dust arrester, it can realize implement it is simple in construction, cheap, safe and reliable, easily operated, to normal
Ironmaking production and overhaul of the equipments influence minimum effect, and maintenance is convenient and post environment is good.
