Description
Technical field
The present invention relates to a kind of metallurgical smelting unit, the oxygen-enriched side-blowing that more particularly to a kind of energy handles leaded secondary material is strong
Change smelting furnace.
Background technology
From the secondary material of other leaded metallurgical slags（Main leaded, bismuth, gold and silver）Recovery rare precious metal has larger warp
Ji and the value of environmental protection., will especially in terms of discharge but national policy is very high to the secondary material processing requirement of leaded metallurgical slag
Ask high.
In order to the recycling of secondary solid waste and harmlessness disposing, usually use side-blown converter, such as Wa Niukefu at present
Stove.Wa Niukefu stoves are mainly made up of cupola well, shaft, furnace roof etc..Cupola well is arranged on bottom and mainly formed by refractory material laying,
Shaft is mainly made up of Copper Water Jacket, and furnace roof is mainly made up of molten steel set.Oxygen-enriched entrance is each provided with shaft and cupola well both sides, it is interior
Footpath is 30-40mm, for blasting oxygen-enriched air into stove, material is stirred vigorously in cupola well and shaft, is rapidly completed molten
Refining and slag making.Furnace roof both sides are provided with air intake, for blasting air into stove, flue dust is further burnt discharge.
Although traditional side-blown converter increases flue, but dust rate still reaches to 3%.Moreover, three layers of body of heater all sets cross air blasting
Mouthful, the air that furnace roof air port blasts makes the sulphur in flue dust generate sulfur dioxide, sulfur dioxide combination high temperature cigarette after further burning
Gas corrodes especially severe to water jacket.In addition, top water jacket uses circulating water, flue gas exit temperature still reaches to 1200 DEG C, led
Cause the refractory brick usually scaling loss of furnace roof exhanst gas outlet.
The side-blown converter of prior art can not the leaded secondary material of efficient process, it is impossible to oxygen-enriched air smelting is realized, in energy consumption and row
Aspect is put to be difficult to reach requirement.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of device damage is less, energy-conserving and environment-protective energy efficient process are leaded
The oxygen-enriched side-blowing intensified smelting stove of secondary material.
In order to solve the above-mentioned technical problem, the oxygen-enriched side-blowing intensified smelting stove that can handle leaded secondary material of the invention,
Including furnace roof, shaft, cupola well, slag road, external crucible, charge door, flue, water jacket of flue, side-blown blast orifice, oxygen-rich mixture cylinder, stove
Slag exports and charging thimble；The furnace roof is arranged above shaft, and the shaft is arranged above cupola well, slag road both ends point
The cupola well and external crucible are not connected, and the charge door and flue are arranged at the top of the furnace roof, and the flue is provided with the cigarette
Road water jacket, the side-blown blast orifice are arranged at shaft two bottom sides, tuyere, the wind are respectively arranged with the side-blown blast orifice
Mouth connects with oxygen-rich mixture cylinder, and the slag outlet and charging thimble are arranged at the external crucible；The water jacket of flue is atomization
Water jacket, waterfog head is provided with the interior separate space of the water jacket of flue, the waterfog head connects water pump by water pipe.
The waterfog head is evenly distributed with multiple row, waterfog head described in each column around the water jacket of flue in interior separate space
A distributive pipe is connected, the distributive pipe is connected with water-main, and the water-main connects the water pump.
The waterfog head is outside plug type shower nozzle, and the outer wall of the water jacket of flue is provided with threaded connection hole, the screw thread
Connecting hole connects with the interior separate space of the water jacket of flue, and the waterfog head is threadedly connected to the threaded connection hole from outside to inside
Interior, the distributive pipe is rubber water pipe, and the water-main is metallic water pipe.
Waterfog head is provided with multiple spray holes in end and sidepiece.
The flue sidepiece is additionally provided with air gun, and the spout of the air gun stretches into the discharge flue of the flue
Interior, the air gun outer end connects nitrogen preparation machine.
The water jacket of flue inwall is fixedly connected with reinforcement, and the reinforcement is fitted and connected with water jacket of flue inwall, institute
State and be fixedly connected by dowel between reinforcement.
The shaft inwall lays alumina firebrick, and hearth wall and side-blown blast orifice inwall lay high magnesium refractory brick.
The tuyere includes nose cone, bott stick and air duct base；The nose cone is connected with the airduct；The nose cone
It is provided with central axis hole；The air duct base includes tilting cartridge and horizontal oxygen-enriched pipe；The inclination cartridge is arranged on horizontal richness
Connected above oxygen pipe and with horizontal oxygen-enriched pipe；The oxygen-enriched pipe of level connects and concentric with the central axis hole；It is described stifled
Stopper rod is socketed in the oxygen-enriched pipe of level and central axis hole and tail end is connected by bolt with the oxygen-enriched pipe tail end of the level；Institute
State bott stick and be provided with axle center hole, described axle center hole one end connects with the central axis hole, the other end by tracheae with it is described oxygen-enriched
Mixture cylinder connects.
The central axis hole inwall of the nose cone is additionally provided with cooling copper tube, and the cooling copper tube is inserted in the bott stick end
It is interior.
The internal diameter of the side-blown blast orifice is 60-100mm.
The invention has the advantages that：
1st, the side-blown blast orifice of one row is respectively only set in shaft both sides, blast orifice quantity is less, reduces flue dust at furnace roof
In sulphur and the combination of oxygen burn again, so as to reduce the generation of sulfur dioxide, corrosion of the flue dust to top water jacket and flue
Less, and due to blasting air capacity reduce so that dust rate is reduced to about 1.5%.
2nd, flue sets water jacket of flue, and water jacket of flue is atomization water jacket, and water is produced in atomization water jacket by waterfog head
Mist cools down to water jacket of flue, and evenly, cooling is more efficient, and it is about 300 DEG C to make stack outlet temperature, it is possible to reduce flue for cooling
The discharge of scaling loss and flue dust, and because the water smoke in water jacket of flue is lighter compared to recirculated water weight so that water jacket of flue knot
Structure is simpler, and cost is lower.
3rd, nitrogen is sprayed into by air gun in flue, flue can be not only cooled, reduce the scaling loss of water jacket of flue, and
And nitrogen is inert gas, is not reacted with sulphur, reduce the generation of sulfur dioxide, so as to reduce the corrosion of water jacket of flue.
The oxygen-enriched side-blowing intensified smelting stove of the present invention is compared with prior art（Identical smelting step）, blast the richness in stove
Oxygen air can contain O from original221% brings up to containing O224-26%, so as to so that Lu Nei material meltings area temperature improves 80-
120 DEG C, and then secondary material process for producing ability 30% i.e. stove unit area can be improved and handle inventory by original 35-
40t/(m2.d 45-50t/ (m) are brought up to2.d), burnt consumption reduces 20-25%, metal recovery rate improves 1.5-2%, flue dust and harmful gas
The discharge of body is greatly reduced, and device damage is less, can realize economic and environment-friendly, the leaded secondary material of efficient process, and its item refers to
Mark is attained by national policy requirement, can be used with industrialization promotion.
