Abstract
The invention discloses a kind of blast furnace taphole Environmental-protecting dust-removing operating room, top is provided with tuyere platform on the outside of the iron mouth of the blast furnace, it is connected that trough is provided with iron mouth, the trough tap drain end is provided with operculum colpi, and closed cavity body operating room is provided with above the trough, and one end and the operculum colpi of the cavity operating room splice, the other end welds with taphole frame, operating room lower opening, for edge of opening with cast house surface using being detachably connected, the cavity operating room is additionally provided with dust arrester.The present apparatus eliminates the suction of iron mouth top and dust hood is absorbed in side, reduces the maintenance that stokehold may move top draft hood；Solve the contradiction of stokehold space for maintenance and dust removal requirement, iron mouth area equipment can be carried out at any time and tap drain is safeguarded；And, heavy castable refractory is not used again, reduce resistance to material cost and maintenance；Finally, stokehold has been effected a radical cure to tap a blast furnace the Heavy environmental pollution problem of field areas, has realized flue dust zero-emission, solve dangerous caused by the big spray of iron mouth.
Description
Technical field
The present invention relates to ironmaking technology field, more particularly to a kind of blast furnace taphole Environmental-protecting dust-removing operating room.
Background technology
Flue dust short time eruption amount in blast furnace discharge yard iron mouth region domain is big, jet power is strong, temperature is high, in hot pressing and the work of furnace pressure
It is spouting from cleek and spread rapidly under, whole cast house is spread in, causes serious environmental pollution.Traditional settling mode
It is to be disposed about removable top draft hood in Tie Kou and side-draught hood, iron mouth region domain are simple without masking, equipment.
The iron mouth of blast furnace is normally at the higher position of blast furnace, and top sets tuyere platform on the outside of iron mouth, during practical operation
Cast house platform can be set in contour position, inhaled for placing the machine of blocking up and trough opened, existing process and equipment using top
Cover and side-draught hood negative pressure exhausting, cover body is near from iron mouth, influences iron jaws equipment and opens the operation and maintenance of the machine of blocking up, and has a strong impact on iron
Ditch tap drain and the maintenance of iron mouth to cover body, it is necessary to first remove, or set removable dust excluding hood.But bad environments herein,
Fume amount is big, temperature is high, and dust excluding hood is easily deformed, and moving equipment failure rate is high, and present enterprise has mostly cancelled mobile cover body.
Due to repair and maintenance and severe stokehold hot environment, blast furnace taphole region is also not provided with preventing the hazard prevention that iron mouth sprays greatly
Facility.
Iron mouth high-pressure injection formula flue dust can not be trapped all, and factory roof need to set final dusting, not met now strict
Environmental requirement, and cause roof structure complicated.
The content of the invention
Goal of the invention：Completely enclosing blast furnace taphole and trough it is an object of the invention to provide one kind neither influences stokehold
The blast furnace taphole Environmental-protecting dust-removing operating room of flue dust zero-emission is realized in operation again.
Technical scheme：The blast furnace taphole Environmental-protecting dust-removing operating room of the present invention, the iron mouth outside top of the blast furnace are provided with wind
Mouthful platform, is provided with that trough is connected, and the trough end is provided with operculum colpi, and the trough, which is arranged on, taps a blast furnace at iron mouth
Disposed on the platform of field, on cast house platform and drive the machine of blocking up, for flushing and casting, one end and the operculum colpi of the cavity operating room are spelled
Connect, the taphole frame of the other end and iron mouth is welded, and is open below, and edge of opening uses with cast house platform surface detachably to be connected
Connect, iron mouth is formed about a closed cavity, the cavity operating room is additionally provided with dust arrester so that iron mouth opens moment spray
Flue dust out is flowed in operating room, then is excluded by dust arrester, it is possible to prevente effectively from the unordered discharge of flue dust, is polluted.
Further, the operating desk and the inside that the machine of blocking up is located at cavity operating room is opened, then can is directly operating
In-house operation opens the machine of blocking up and other equipment.
Further, the dust arrester includes the depression dust-removing pipe for being arranged on cavity operating room upper outside, and the negative pressure is removed
Dirt pipe inside cavity operating room with connecting.
Wherein, the cavity operating room includes the detachable frame pre-set and is spliced into closing with detachable frame
The detachable hanging plate of cavity body structure, repair in stokehold and during overhaul, there is no removing top to inhale and the problem of side absorbs dust hood, remove extension
Plate, framework can also be removed as needed.
, can be directly in it be corresponding because the inwall and top plate of the cavity operating room increase the distance with molten iron level
Surface sets one layer of ceramic beaverboard, and its proportion only has 1/the tens of fire-proof spray coating, solve stokehold largely spray it is heat-insulated
The problem of material installation quality is big, maintenance workload is big.
Beneficial effect：Compared with prior art, advantages of the present invention is：(1) first, iron mouth top is eliminated to inhale and side absorption
Dust hood, reduce the maintenance that stokehold may move top draft hood；(2) secondly, solve the contradiction of stokehold space for maintenance and dust removal requirement,
Iron mouth area equipment can be carried out at any time and tap drain is safeguarded；(3) again and, do not use heavy refractory material, reduce resistance to material cost and
Maintenance work；(4) finally, stokehold has been effected a radical cure to tap a blast furnace the Heavy environmental pollution problem of field areas, has realized flue dust zero-emission, solve
It is dangerous caused by the big spray of iron mouth.
Brief description of the drawings
Fig. 1 is apparatus of the present invention structural representation.
