Description
Technical field
This utility model relates to the reduction furnace that a kind of flue dust is few.
Background technology
In traditional lead smelt technique, the dust rate of reduction phase is up to 30%-35%, causes substantial amounts of lead and is being
System circulates.Bottom blowing molten pool reducing furnace of the prior art, bottom reduction furnace or bottom side spray gun sprays to melt in stove
Enter oxygen-natural gas or oxygen-coal gas, add carbon granule, final output lead bullion, flue gas and end at reduction furnace top charge door simultaneously
Slag.Solve the heat content Utilizing question of lead oxidation slag, but cost is high.Additionally, the exhaust gas volumn produced is big, dust rate is high, lead
Direct yield is low, and recovering effect is poor, and the heat that high-temperature flue gas is taken away is many, and energy consumption increases accordingly.
Publication No. CN101839625A, the equipment of entitled lead skim reduction furnace disclose one and utilize coal dust to carry out material
Reduction, thus reduce the way of flue dust.
But, it was discovered by researchers that the shortcoming of prior art is: 1. pulverized coal particle is fine and smooth, during ejection, one
Denier blocks, and can produce potential safety hazard；2. ejection coal dust needs high pressure, and pressure is unbalanced, can cause the sprinkling of coal dust not
Uniformly.
Summary of the invention
This utility model is contemplated to solve existing middle coal dust and sprays uneven, to be susceptible to blocking problem, further
Provide the reduction furnace that a kind of flue dust is few.
For solving the problems referred to above, content of the present utility model is as follows:
The reduction furnace that a kind of flue dust is few, including body of heater, body of heater is provided with charge door, lead outlet, slag tap, drain, goes out
Mouth, the heater that material in body of heater is heated and a number of reducing agent material spray pipeline being located in body of heater, institute
The feeding mouth stating reducing agent material spray pipeline extends to be connected with reducing agent raw material cabin outside body of heater, and the discharging opening parallel connection of shower nozzle is multiple
The shower nozzle of space divergence.
Described reducing agent material spray pipeline is provided with pressure-detecting device.
The space angle of 20～120 degree is there is between described shower nozzle.
Described shower nozzle is flexibly connected for dismountable with between the discharging opening of shower nozzle.
Outlet pipe also it is set with in described reducing agent material spray pipeline.
The height of described the top shower nozzle is less than the height of material in reduction furnace.
Staggered along the position of reducing agent material spray pipeline each described in the circumferential direction of described reduction furnace furnace wall, form 10～30
The alternate angle of degree.
Described heater is a number of electrode, and described electrode is spaced with described reducing agent material spray pipeline.
The beneficial effects of the utility model are: 1. reflection is the most thorough, and the response rate of lead is high.Consumption coal amount is few, cigarette
Narrow-minded, dust rate is low；2. each shower nozzle is detachable, it is simple to standardized management；3. the direction of shower nozzle ejection reducing agent is with space
Angular dispersed, makes mixing effect more uniform；Pressure-detecting device is the most rationally set, monitors the duty of shower nozzle in real time, anti-
Only blocking, on-call maintenance.

Fig. 2 is this utility model body of heater, heater and the schematic cross-section of reducing agent material spray pipeline.
Each component names in figure: 1. charge door；2. outlet flue；3. body of heater；4. electrode；5. reducing agent material spray pipeline；6. also
Former dose of raw material cabin；7. support means；8. tumbler；9. main burner mouth；10. slag tap；11. shower nozzles.
Detailed description of the invention
Embodiment 1, the reduction furnace that a kind of flue dust is few, such as Fig. 1 to 2, including body of heater 3, body of heater 3 is provided with charge door 1, goes out lead
Mouth, slag tap 10, drain, outlet flue 2, the heater that material in body of heater 3 is heated and be located in body of heater 3 one
The reducing agent material spray pipeline 5 of determined number, the feeding mouth of described reducing agent material spray pipeline 5 extends to outside body of heater 3 and reducing agent raw material
Storehouse 6 is connected, the shower nozzle 11 of the discharging opening of shower nozzle multiple space divergences in parallel.The shower nozzle of space divergence shape, the surrounding of phase space
Direction ejection reducing agent, will not be formed look after less than corner, the spray area of reducing agent is more uniformly distributed, improve reflection effect
Really, the most just reduce flue dust goes out dirt rate.
Described reducing agent material spray pipeline 5 is provided with pressure-detecting device.When blocking occurs in shower nozzle, internal pressure can increase
Greatly, being now reflected on pressure-detecting device, staff can find to judge in time, or changes or maintenance.Avoid into one
Step is destroyed, and also reduces loss of efficiency.
The space angle of 20～120 degree is there is between described shower nozzle 11.
Described shower nozzle 11 is flexibly connected for dismountable with between the discharging opening of shower nozzle.Parts are realized standardization by this design
Management, it is simple to the maintenance in later stage and replacing
Outlet pipe also it is set with in described reducing agent material spray pipeline 5.
The height of described the top shower nozzle 11 is less than the height of material in reduction furnace.
Described heater is a number of electrode 4, and described electrode 4 is spaced with described reducing agent material spray pipeline.
On the one hand ensure the uniform release of reducing agent, on the other hand ensure electrically heated temperature equalization.
Embodiment 2, the present embodiment principle is with embodiment 1, concrete difference, along the circumference of described reduction furnace furnace wall
Described in direction, the position of each reducing agent material spray pipeline 5 is staggered, forms the alternate angle of 20 degree.The existence of alternate angle, protects further
Demonstrate,prove the equilibrium executing material.
