Description
Technical field
This utility model belongs to Copper making anode furnace technical field, specifically one Copper making anode furnace pure oxygen combustor,
This utility model can avoid pure oxygen combustion-supporting burning to cause the impact on the anode furnace stove longevity of the Lu Nei localized hyperthermia.
Background technology
At present, Pure Oxygen Combustion Technology progressively substitutes the combustion-supporting burn application of conventional air in Copper making anode furnace, it is achieved energy-conservation
Reduce discharging.The feature of Pure Oxygen Combustion Technology is intensity and speed, the combustion flame temperature that pure oxygen combustion-supporting improves Theoretical combustion reaction
Height, exhaust gas volumn are few.Although Pure Oxygen Combustion Technology there is the problem that when being applied in Copper making anode furnace and inhales dilute by volume at present
Releasing principle, oxygen and natural gas utilizes high-temperature furnace gas to obtain dilution reduction flame concentration heat release after burner sprays into burner hearth, but
Mix purity at burner exit position oxygen and natural gas the most higher, cause to exist near burner position and concentrate vigorous combustion mistake
The phenomenon of heat, accelerates the position such as furnace lining, burner block body wear rate above copper anode furnace headwall, burner block, causes the stove longevity
Reduce.Therefore, flame adjusting during pure oxygen combustion-supporting burning is realized in the urgent need to a kind of corrective measure of searching, it is to avoid pure oxygen combustion-supporting
The burning impact on the anode furnace stove longevity.
Summary of the invention
The purpose of this utility model seeks to solve to there is anode furnace end currently with the anode furnace of pure oxygen combustion-supporting burner
Above wall, burner block, the position such as furnace lining and burner block body loss speed is accelerated, the problem that the stove longevity reduces, it is provided that a kind of Copper making
Anode furnace pure oxygen combustor.
A kind of Copper making anode furnace pure oxygen combustor of the present utility model, by burner block, pure oxygen air gun, the spray of pure oxygen air gun
Head, natural air gun, natural gas gun sprayer composition, described pure oxygen air gun, natural air gun the port of export respectively with purity oxygen gun sprayer,
Natural gas gun sprayer is connected, particularly: described natural air gun overcoat closes the tune flame air-casing of one end open equipped with an one end
Cylinder, and become an annular to adjust flame air chamber with natural gas gun-shaped, adjust the port of export of flame air-casing cylinder to be connected with natural gas gun sprayer；Institute
State pure oxygen air gun, natural air gun, the tune flame the most external metal hose of air-casing cylinder, metal hose is respectively arranged with switch valve, effusion meter
With regulation valve.
Adjusting the tune flame gas being filled with in flame air chamber described in this utility model is noble gas (usually using nitrogen) or pressure
Contracting air.
2-3 times of (the generally 0.3-that pressure is pure oxygen pressure adjusting flame gas in flame air chamber is adjusted described in this utility model
0.5MPa), adjust flame gas 0.2-0.4 times that flow is gas discharge.
This utility model, after flame air-casing cylinder debug by natural air gun overcoat, is adjusted the pressure of flame gas, firing rate by regulation, is made
Adjust flame gas to mix with natural gas at natural air gun burner, rapidly natural gas can be broken up dilution and part cladding is brought into burner hearth
Burn with oxygen mix the most again, stretched the length of combustion flame, make in-furnace temperature more uniform, it is to avoid burner headwall and
Burner block hot-spot and flame fix scaling loss local liner for a long time, eliminate pure oxygen combustion-supporting and burn to anode furnace liner and stove
The impact of head end wall, burner and burner block, effectively extends the anode furnace stove longevity.
This utility model has the advantage that
1. improve simple, easy to operate；
2. adjusted pressure and the flow of flame gas by regulation, it is possible to achieve the regulation on a large scale of combustion flame length, typically may be used
Reach 3-10m；
3. by the regulation of the length of flame, make in-furnace temperature more uniform, it is to avoid hot-spot phenomenon occurs, eliminate pure
The oxygen and aiding combustion burning impact on the stove longevity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 burner block, 2 pure oxygen air guns, 3 purity oxygen gun sprayers, 4 natural air guns, 5 natural air gun sprays
Head, 6 adjust flame air-casing cylinder, and 7 adjust flame air chamber, 8 metal hoses, 9 switch valves, 10 effusion meters, 11 regulation valves.
Detailed description of the invention
Embodiment 1
Seeing Fig. 1, the technical scheme of the present embodiment is: a kind of Copper making anode furnace pure oxygen combustor, by burner block 1, pure
Oxygen lance 2, purity oxygen gun sprayer 3, natural air gun 4, natural gas gun sprayer 5 form, described pure oxygen air gun 2, the going out of natural air gun 4
Mouth end is connected with purity oxygen gun sprayer 3, natural gas gun sprayer 5, particularly respectively: be set with one outside described natural air gun 4
The tune flame air-casing cylinder 6 of one end open is closed in one end, and forms an annular tune flame air chamber 7 with natural air gun 4, adjusts flame air-casing cylinder 6
The port of export be connected with natural gas gun sprayer 5；Described pure oxygen air gun 2, natural air gun 4, the tune respective external metal of flame air-casing cylinder 6
Flexible pipe 8, metal hose 8 is respectively arranged with switch valve 9, effusion meter 10 and regulation valve 11.
Adjusting the tune flame gas being filled with in flame air chamber 7 described in the present embodiment is nitrogen, certainly can also use other indifferent gas
Body or compressed air.
2-3 times of (the generally 0.3-that pressure is pure oxygen pressure adjusting flame gas in flame air chamber 7 is adjusted described in the present embodiment
0.5MPa), adjust flame gas 0.2-0.4 times that flow is gas discharge.
Pure oxygen combustor of the present utility model, is to verify really have and prevent anode furnace localized burn through actual production
Too fast effect.Daye coloured smelting factory 2# Copper making anode furnace is introducing the Pure Oxygen Combustion Technology initial stage, does not apply this reality
By novel improvement technology, after producing 20 days, there is 1.5m below copper outlet in anode furnace, to burner 1m right position refractory brick
Scaling loss is too fast, the phenomenon that furnace shell is rubescent, after using this utility model to improve, then does not occurs that anode furnace localized burn is too fast
Phenomenon, compensate for the drawback that Pure Oxygen Combustion Technology brings.
