Description
Technical field
The utility model relates to a kind of Cowper stove of blast furnace ironmaking, especially Cowper stove bottom short circuit repairing device.
Background technology
Cowper stove is a kind of blast funnace hot blast stove of common type.The combustion chamber of Cowper stove is arranged on bottom, partition wall is there is between combustion chamber of internal-combustion stove and its regenerator, in normal productive process, curtain wall structure is complete without when being out of shape, and combustion product gases is diffused by combustion chamber-vault-regenerator lattice brick-fire grate-flue-chimney.
If but when there is local collapse, distortion, gap on partition wall or hotblast stove big-wall, the negative pressure that coal gas and air can be formed due to the draft of flue from above-mentionedly subsiding, be out of shape, gap position directly enters into regenerator and burns, thus affect hotblast stove trouble-free burning, affect the work-ing life of hotblast stove.
Bottom short circuit refers to that larger masonry gap appears in big-wall between hotblast stove gas inlet and gas entry or combustion chamber, combustion air and coal gas are mixed into regenerator in advance by gap, in the enrichment of regenerator bottom, burning or pinking is there is after reaching combustion conditions, cause blast furnace impaired, thus affect hotblast stove trouble-free burning.After general bottom short circuit occurs, the technical measures taked are laid bricks again build by laying bricks or stones for being removed internal refractory, but long in time limit, and investment is large, and have a strong impact on blast furnace and normally produce.
Utility model content
Problem to be solved in the utility model is to provide Cowper stove bottom short circuit repairing device, this device is the prosthetic device that larger masonry gap appears in big-wall between a kind of gas inlet of Cowper stove bottom and gas entry or combustion chamber, realize the passage of shutoff coal gas and air, avoid the mixed firing in advance of coal gas and air.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in that
Cowper stove bottom short circuit repairing device, described device comprises gas line tightness system, air line tightness system, hotblast stove eyes corner seals;
Gas line tightness system is arranged on inside of gas pipeline, comprise standing bolt, take-up device, the whole ring sealing plate of band flanging and fibre product, standing bolt head and gas line inwall are fixed, take-up device one end is connected to standing bolt afterbody, the whole ring sealing plate of its other end puller strap flanging and shrouding one end is fixedly connected on gas line inwall, the flanging of the shrouding the other end is fastened on combustion chamber outer shroud brick sidewall, between the flanging of outer shroud brick sidewall and the shrouding the other end, gap filling fibre product, shrouding offers grout hole;
Air line tightness system is arranged on air line ingress on the outer shroud brick of combustion chamber, adopts mould material shutoff sealing;
Hotblast stove eyes corner seals is arranged in hotblast stove big-wall and combustion chamber outer shroud brick and stings and build position, is stinging perforate mud jacking sealing on the hotblast stove big-wall building position.
Further, described gas line tightness system is arranged between blast furnace staying operational period, take to be welded to gas line ingress and be with the whole ring sealing plate of flanging, and pour into slurry by grout hole and seal, avoid coal gas to leap up Lou from the gap of laying bricks of gas line and hotblast stove big-wall and combustion chamber outer shroud brick;
Further, described air line tightness system is arranged between blast furnace staying operational period, and on the outer shroud brick of combustion chamber, air line ingress takes mould material shutoff air and coal gas to leap up leakage passage;
Further, described hotblast stove eyes corner seals is arranged on blast funnace hot blast stove and burns stove production period, sting in hotblast stove big-wall and combustion chamber outer shroud brick and build position perforate mud jacking, shutoff coal gas, air sting via combustion chamber outer shroud brick and hotblast stove big-wall the leakage passage of leaping up that the dilatation joint the building position combustion chamber entered between combustion chamber outer shroud brick and combustion chamber partition wall is mixed to form in advance.
The utility model beneficial effect compared to existing technology:
The utility model structure is simple, easy to operate, improves hotblast stove repairing effect, saves repair expense and time, improve the work-ing life of hotblast stove.Specifically:
1, solve the coal gas advanced combustion that the short circuit of Cowper stove bottom causes, ensured the safety in production of the processing unit such as fire grate, pillar, avoid regenerator generation gas-fired, pinking to normal impact of producing.
2, the damping down construction period is short, can complete, additionally do not cause blast furnace staying operation during the normal periodical repair of blast furnace.
3, the utility model Treatment process is comprehensive, complete, the whole shutoff of Lou passage of issuable coal gas, air being leapt up, and is to improve terms of settlement after defect appears in the inner masonry of hotblast stove.
4, operation is simple and reliable for the utility model, construction and Master Cost less.
