Description
Technical field
Zinc powder reclaimer field is the utility model is related to, dress is settled more particularly to a kind of decompression for being used to reclaim zinc powder
Put.
Background technology
China's smelting furnace production zinc powder, which is come from the 1970s, being developed by 600KVA rectangle electric arc furnaces by 2000, to be changed
Into 800KVA circular electric arc furnaces.First 2000KVA circular electric arc furnaces was built up by 2006.During this period, smelting technique has
Very big lifting, it can be contained till now by certain processing and formula using many kinds using single raw material calcining from originally
The miscellaneous material of zinc is produced.But the technology for the zinc powder of off-gas recovery containing zinc for reacting to obtain by furnace reduction is very backward.
Backwardness is mainly manifested in the following aspects：1st, the zinc powder rate of recovery is low, wastes mineral resources；2nd, metal member in waste gas
Cellulose content is high, Heavy environmental pollution；3rd, zinc powder recovery process is backward and zinc powder reclaimer is simple and crude, poor safety performance；4th, it is traditional
Zinc powder recovery process, zinc powder recovery benefit it is low；5th, traditional zinc powder recovery process is operated, it is necessary to put into substantial amounts of labour
Inconvenience；6th, traditional zinc powder recovery process continuity difference is, it is necessary to the cleaning that often stops production.
Existing zinc powder recovery method is all that the air inlet of condenser is opposite molten using first by condenser on slide rail
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, continue to be fed into next condenser and condense again, next unrecovered complete cigarette containing zinc of condenser
Pneumatic transmission enters bagroom processing.
Many drawbacks in practical operation be present in prior art：
1st, because the flue gas containing zinc of furnace gas export discharge is that temperature is very high first, 1050~1100 degree or so are reached, and
In order to allow stove energy normal operation, the pressure of furnace gas export also reaches greatly 20Pa~30Pa very much, also, flue gas containing zinc is originally
One mixed stocker, for mixed stocker when HTHP, explosion limit is very high, so often being exploded when cleaning and putting powder
Accident, damages condenser and cloth pocket even injures people or thing；
2nd, flue gas containing zinc is directly entered that condenser is very fast to the cold, and zinc fume understands some and is directly changed solid spelter, this
Sample inconvenience uses helical feed.And because 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 height after cold, it is necessary to could enter vibratory sieve.
3rd, also have the drawbacks of very big be exactly flue gas containing zinc out of stove out just to during furnace gas export because to lump to the cold,
As beaten not in time, the refractory brick surface of furnace gas export will be firmly bonded in.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 be cleared up for this, still, unique method of cleaning is exactly
The height of stove is broken, pause production, the charging aperture above furnace roof opened, allows in stove the zinc fume and other restored
Gas, discharged above furnace roof, after reducing pressure, a condensation pulley is pulled away from furnace gas export along track.Then open
Begin cleaning, after cleaning out, then condenser is shifted onto furnace gas export and fixed, such operation is not only inconvenient but also have a lot
Potential safety hazard.Productivity effect is low, waste of resource, pollutes air.
Chinese utility model patent such as Patent No. CN201110106817.3 " is given birth to using treating zinc-containing miscellaneous material through electric furnace
The method for producing zinc powder ", disclose a kind of method that zinc powder is produced using treating zinc-containing miscellaneous material through electric furnace.Matched somebody with somebody by the miscellaneous materials quantitative containing zinc
Material, containing the miscellaneous material mixture granulation of zinc, containing the zinc miscellaneous roasting of material particle, baking flue gas dust collection, electro-smelting, zinc powder condensing and melting cigarette
Gas is gathered 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
Technique and equipment caused by former during the recovery of flue gas condensing containing zinc zinc powder is very simple and crude and following ask be present after work a period of time
Topic：
1st, due to temperature difference between smelting furnace and furnace gas export be present, flue gas containing zinc smelting furnace furnace gas export to the cold
Caking causes furnace gas export to occur blocking, it is necessary to the cleaning that stops production；
2nd, 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 there is fraction of impurity and material powder to 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, is directly changed spelter.
3rd, the zinc powder temperature that condenser is condensed into is very high, it is impossible to it is directly entered after vibratory sieve screened, it is necessary to be cooled down,
Vibratory sieve material screen could be carried out；
4th, it is now cold, it is necessary to be removed condenser from furnace gas export by slide rail when the blocking of furnace gas export is cleared up in stopping production
The air inlet of condenser is easily accessible cold air and mixes generation blast with remaining flue gas containing zinc in condenser, and security is low；
5th, 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 occur a kind of easy-to-operate, energy-conserving and environment-protective, can improve zinc powder quality and the rate of recovery with condensation
The decompression sedimentation device that device coordinates.
