Description
Technical field
What the present invention relates to is a kind of silicon brick hot-blast stove insulation heat discharging method being applicable to iron and steel metallurgical industry.
Background technology
In the prior art, known technology is, iron and steel metallurgical industry is used for the silicon brick hot-blast stove of iron-smelting blast furnace, blast furnace overhaul shutdown period, because hotblast stove top employs part silica brick, according to the characteristic of silica brick, because of in the crystal transition process of residual quartz in silica brick, its coefficient of expansion is comparatively large, causes the intensity of silica brick to slacken, there is greater risk.Hotblast stove cooling is unreasonable, also easily damages masonry, has influence on hotblast stove work-ing life, intermittently need carry out burning stove to hotblast stove, make it to remain in specialized range.When the heat storage of hotblast stove middle and lower part is too much, fragile metal construction and fire grate.Just need by the method for heat extraction, heat to be discharged.The scheme in the past adopted provides power to produce combustion air by burner blower, shunt total pipe connected pipe motorized valve through combustion air house steward by combustion air house steward and cold wind and enter cold wind shunt conduit, enter chamber of hot-blast stove by heat extraction stove flue arm, the gas after exchange enters in air through hot air duct, refluence pipe.Burner blower uses high-voltage motor, and during operation, power consumption is higher, causes energy dissipation.
Summary of the invention
Object of the present invention is exactly for the deficiency existing for prior art, and providing a kind of silicon brick hot-blast stove to arrange the technical scheme of warm method, the program does not need to use high-voltage motor air-supply, utilizes principle of negative pressure, carry out heat exchange by air intake to silicon brick hot-blast stove, realize row's temperature of silicon brick hot-blast stove.
This programme is achieved by the following technical measures: a kind of silicon brick hot-blast stove arranges warm method, comprises the steps:
1) cold wind is shunted house steward to be communicated with burner blower blast pipe, cold wind shunting house steward is communicated with silicon brick hot-blast stove by cold wind shunt pipe, and silicon brick hot-blast stove is communicated with heat extraction house steward, and heat extraction house steward is communicated with refluence damping down pipe;
2) the heat extraction stove cold wind diverting valve on cold wind shunt pipe, the hot blast valve on heat extraction house steward and the reverse flow valve on refluence damping down pipe is opened, air in cold wind shunt pipe enters after silicon brick hot-blast stove carries out heat exchange, after hot-blast main, refluence damping down pipe, enter in air, in such cold wind shunt pipe, just form negative pressure;
3) the cold wind shunting house steward diverting valve on cold wind shunting house steward, cold wind shunting house steward trip valve, burner blower inlet adjusting valve is opened, under the effect of negative pressure, after air enters into cold wind shunting house steward, cold wind shunt pipe by burner blower blast pipe, enter in silicon brick hot-blast stove, after heat exchange, after hot-blast main, refluence damping down pipe, enter in air.
Described heat extraction stove cold wind diverting valve is motorized valve.
Described step 2) in after air enters silicon brick hot-blast stove by cold wind shunt pipe, first carry out heat exchange by entering chamber of hot-blast stove after the flue gas arm in silicon brick hot-blast stove.Air enters in chamber of hot-blast stove and carries out heat exchange with the silica brick in chamber of hot-blast stove.
After air enters silicon brick hot-blast stove by cold wind shunt pipe in step 3), first carry out heat exchange by entering chamber of hot-blast stove after the flue gas arm in silicon brick hot-blast stove.Air enters in chamber of hot-blast stove and carries out heat exchange with the silica brick in chamber of hot-blast stove.
Described cold wind shunting house steward diverting valve is the manual diverting valve of cold wind shunting house steward.
Described step 2) in form negative pressure in cold wind shunt pipe while, also form negative pressure in silicon brick hot-blast stove.
The beneficial effect of this programme can be learnt according to describing of such scheme, owing to first opening heat extraction stove cold wind diverting valve, hot blast valve, reverse flow valve in this scenario, the air of such cold wind shunt pipe is just introduced into the flue arm in silicon brick hot-blast stove, entering regenerator, carry out sufficient heat exchange, enter air finally by refluence damping down pipe, such cold wind shunt pipe will form negative pressure; Now open cold wind shunting house steward diverting valve, cold wind shunting house steward trip valve, burner blower inlet adjusting valve, outside air will enter into silicon brick hot-blast stove, carries out row's temperature, and whole process does not need to use motor, not only achieve the object of cooling, and do not need extra power.
As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent in the present invention.
