Description
Technical field
The utility model is related to zinc powder recycling fields, and generation is restored in smelting furnace from containing Zn scrap returns more particularly to a kind of
The system that zinc powder is recycled in flue gas containing zinc.
Background technology
China's smelting furnace production zinc powder, which is derived from the 1970s, being developed by 2000 by the rectangle electric arc furnaces of 600KVA, to be changed
At the round electric arc furnaces of 800KVA.The round electric arc furnaces of first 2000KVA was built up by 2006.During this period, smelting technique has
Prodigious promotion can be contained by certain processing and formula using many kinds from originally using single raw material calcining till now
The miscellaneous material of zinc is produced.But it is very backward by the technology of the furnace reduction zinc powder of off-gas recovery containing zinc obtained by the reaction.
Backwardness is mainly manifested in the following aspects：1, the zinc powder rate of recovery is low, wastes mineral resources；2, metal member in exhaust gas
Cellulose content is high, Heavy environmental pollution；3, zinc powder recovery process is backward and zinc powder reclaimer is simple and crude, poor safety performance；4, traditional
Zinc powder recovery process, zinc powder recycle benefit it is low；5, traditional zinc powder recovery process needs to put into a large amount of labour, operation
It is inconvenient；6, traditional zinc powder recovery process continuity is poor, needs the cleaning that often stops production.
Existing zinc powder recovery method is all using first by condenser on sliding rail, and the air inlet of condenser is opposite molten
The furnace gas export of furnace so that the flue gas containing zinc restored in smelting furnace can be directly entered condenser and be condensed, condensed device
Unrecovered complete flue gas containing zinc continues to be fed into next condenser and condenses again, next unrecovered complete cigarette containing zinc of condenser
Pneumatic transmission enters bagroom processing.
There are many drawbacks in practical operation for the prior art：
1, because the flue gas containing zinc of furnace gas export discharge is that temperature is very high first, reach 1050~1100 degree or so, and
In order to allow stove energy normal operation, the pressure of furnace gas export reaches 20Pa~30Pa, also, flue gas containing zinc originally one is mixed
Collaboration, for mixed stocker when high temperature and pressure, explosion limit is very high, so the explosion accident frequent occurrence when cleaning and putting powder,
It damages condenser and bagroom even injures people or object；
2, flue gas containing zinc is directly entered that condenser is very fast to the cold, and zinc fume understands some and directly becomes solid spelter, this
Sample inconvenience uses helical feed.And since the pressure of the flue gas containing zinc is very big, there are fraction of material and impurity can be with cigarette in stove
Gas brings condenser into so that the quality of powder is impacted because, a condenser directly against furnace gas export, so, in a condenser
Temperature and pressure it is all very high, condensation effect is poor, and condensed zinc powder temperature is high, needs that vibrating screen could be entered after cold.
3, condensed zinc powder inconvenience spiral and conveyer belt conveying.It can only be waited in the local trepanning by condenser bottom
Have and places into vibrating screen after cold from powder is put into closed container from hole when powder.As pressure can allow many cigarettes containing zinc
Gas enters two condensers, has many zinc powders that can be brought directly to cloth pocket with flue gas after the condensation of two condensers.Cloth bag is not having
, can be very swollenly bulging by air-flow in the case of decompressor, it is unable to reach the effect gathered dust in this way, understands some zinc powder and is brought into
In air, not only waste of resource but also air had been polluted in this way.
4, also have a prodigious drawback be exactly flue gas containing zinc out of stove out just to when furnace gas export because to lump to the cold,
If beaten not in time, it will firmly be bonded in the refractory brick surface of furnace gas export.Ordinary circumstance, will be furnace gas at 5-10 days
Outlet obstruction so that the pressure in stove constantly increases, and causes danger, and must clear up thus, and still, unique method of cleaning is exactly
The height of stove is broken, the charging aperture above furnace roof is opened in pause production, allow in stove the zinc fume restored and other
Gas is discharged above furnace roof, and after reducing pressure, a condensation pulley is pulled away from furnace gas export along track.Then it opens
Begin cleaning, after cleaning out, then condenser is shifted onto furnace gas export and is fixed, such operation is not only inconvenient but also have very much
Security risk.Productivity effect is low, waste of resource, pollutes air.
5, zinc powder when condensation of the condenser pipe in condenser can attach on condensation tube wall, can slowly lose condensation effect
Fruit also only breaks height to clear up condenser pipe, pause production.Condenser is pulled away from furnace gas mouth, is waited in condensers
Condenser pipe is just begun a clean up when gas is discharged into certain naturally.
As the Chinese utility model patent of Patent No. CN201110106817.3 " is produced using treating zinc-containing miscellaneous material through electric furnace
The method of zinc powder " discloses a kind of method producing zinc powder using treating zinc-containing miscellaneous material through electric furnace.Matched by containing the miscellaneous materials quantitative of zinc
Material contains the miscellaneous material mixture granulation of zinc, contains the miscellaneous material particle roasting of zinc, baking flue gas dust collection, electro-smelting, zinc powder condensing and melting cigarette
Gas gathers dust process, and zinc powder is produced using the miscellaneous material containing zinc.But the patent is disadvantageous in that：This method is gone back in processing electric furnace
It is asked there are following after technique and equipment when originating in the raw recycling zinc powder of flue gas condensing containing zinc is very simple and crude and work a period of time
Topic：
1, due between smelting furnace and furnace gas export there are temperature difference, flue gas containing zinc smelting furnace furnace gas export to the cold
Caking causes furnace gas export to block, and needs to stop production and clear up；
2, smelting furnace will directly contain zinc flue gas and be conveyed to condenser, and the temperature of the flue gas containing zinc is very high, and pressure is also very
Greatly, cause zinc vapor condensing effect excessively poor, and have fraction of impurity and raw material powder that can be brought directly to condenser shadow in stove
Ring the quality of zinc powder, and flue gas containing zinc is directly entered condenser to have a fraction of zinc fume very fast to the cold, directly becomes spelter.
3, the zinc powder temperature that condenser is condensed into is very high, cannot directly enter vibrating screen and is screened, after needing cooling,
It could carry out vibrating screen material screen；
4, it when the blocking of halt production cleaning furnace gas export, needs to remove condenser from furnace gas export by sliding rail, it is cold at this time
The air inlet of condenser is easily accessible cold air and mixes generation explosion with remaining flue gas containing zinc in condenser, and safety is low；
When the zinc powder 5, adhered on the condenser pipe of halt production cleaning condenser, condenser is opened, needs to be manually entered condenser
It is interior to clear up the zinc powder for being adhered to condenser pipe, but condenser enters cold air and can be mixed with remaining flue gas containing zinc in condenser after opening
It closes and generates explosion, not only high labor cost, but also manual security's property is low.
6, because flue gas containing zinc is directly entered condenser, condensation effect is poor, and the rate of recovery is low, waste of resource, pollutes environment.
Therefore, it is necessary to a kind of safe operation and conveniently, energy conservation and environmental protection, moreover it is possible to improve the zinc powder rate of recovery and zinc powder quality occur
Recycling zinc powder system.
