Description
Technical field
The present invention relates to a kind of inverted cone sieve dish ammonia efficient chemical combination leaching device of No leakage formula copper mine.
Background technology
Copper mine in nature is that in the form of copper sulfide, copper sulfide is molten in the ammonia of suitable concentration with the presence of quite a few
In liquid, there are enough air to blast（Mainly oxygen participates in reaction）, complex compound can be formed and dissolved, complete chemical combination and leach molten
Xie Hou, then carry out separation of solid and liquid and can carry out next step operation.
Therefore, the chemical combination leaching device of copper mine is the essential key equipment of process for copper processed, but existing copper mine chemical combination
There are two big defects in leaching device, so as to constrain the development of copper technology processed.One is that air blasts insufficient and inconvenience, vulcanization
The chemical combination leaching velocity of copper is slow, efficiency is low, it is necessary to increasing special air blasts equipment, increases equipment investment, and also causing need not
The trouble wanted；Two is that ammonia is easily leaked, because ammonia is with excitant high, volatile toxic and harmful, thus to environment
Influence is very big, also very big to the loss of ammonia, but if being reacted using Sealing Arrangement, then easily triggers the safe things such as blast
Therefore.
Therefore, if can design a kind of air it is automatic it is convenient blast, ammonia be not easy to leak and be not pressure vessel copper mine
Efficient chemical combination leaching device, then with important actual application value.
The content of the invention
The technical problem to be solved in the present invention is exactly to overcome the deficiencies in the prior art, there is provided a kind of simple and practical, empty
Gas it is automatic it is convenient blast, ammonia be not easy to leak and be not pressure vessel the efficient chemical combination leaching of inverted cone sieve dish ammonia No leakage formula copper mine
Go out device.
To overcome the deficiencies in the prior art, the present invention to take following technical scheme：
A kind of inverted cone sieves the dish ammonia efficient chemical combination leaching device of No leakage formula copper mine, including chemical combination leaching barrel and tail gas clean-up

Close and air（Oxygen）Supply.Liquid stream can be collected by inlet simultaneously, be backflowed by return tube, formed bottom and gushed
Stream, effectively prevents from boring the deposition of substrate material and blocking.
The logical steam of heating jacket or hot water realize heat temperature raising, can also lead to cold water and be lowered the temperature, and the gas for overflowing liquid level is same
When can carry vapor, ammonia as tail gas, gaseous mixture realizes recovery and tail gas clean-up by exhaust purifier, it is to avoid ammonia is let out
Leakage.
Exhaust purifier has the chuck can to lead to cooling water or chilled water, intervalve constituted with helical fin cylinder it is jacket structured,
Overflow gas and top is risen to again by the downward water conservancy diversion of helical fin cylinder by intervalve, due to having spiral wing in helical fin cylinder
Piece, can realize guiding rotation to gas in interlayer, produce downward helical air flow path, be overflowed by helical fin cylinder lower edge
And dish is sieved through inverted cone, and being overflowed from liquid level after good diffusion and risen, air-flow is forced cyclone in cyclone by spinning disk effect, can
With the liquid phase that effective centrifugation may wherein be carried, discharge gas is set to realize purification, liquid phase meeting automatic dipping wall flows back downwards.
The clean-up effect of exhaust purifier depends on overcoming difficulties the heat and mass transport for carrying out, the wherein controlled overflow pipe of liquid level
Position, many rear overflow pipes of condensate liquid can overflow, returning liquid inclined tube can effectively prevent return slag from blocking, chilled water and tail gas in chuck
Liquid phase has overall heat-transfer coefficient very high in clarifier, and liquid is good because temperature and gas overflowing can be produced in exhaust purifier
Automatic stirring convection circulation, helical fin cylinder has bigger gas phase side heat exchange area, while subsurface liquid phase can be passed efficiently
Heat, cooling ammonia condensing is realized to gas phase in cylinder, and the cryogenic gas that ullage point is spilled off realizes gas phase precooling in cylinder；Spiral wing
Swirling eddy can promote heat and mass transfer with effective disturbance air film in piece cylinder, carry out one-level cooling, condensation, gas-liquid separation, then
Through inverted cone sieve dish liquid phase layer good diffusion, two grades of heat and mass transfers of directly contact are realized, realize that ammonia efficiently catches, rise gas
Mutually finally realize cyclonic separation once again in cyclone, emission is reached purification and require.
The design is larger in air capacity using basic closed interlayer pot chemical combination leaching system, then supporting tail gas recycle ammonia
In the case of, the condensation and effectively recovery of ammonia are realized, while completing tail gas clean-up discharge.Largely exist in incoagulable gas and serious
In the case of influence condensing interface heat and mass transport state, the high-efficiency condensation for realizing ammonia catches.
Compared with prior art, beneficial effects of the present invention are also resided in：
Chemical combination leaches atmosphere in the tub（Oxygen）Automatic convenient, the liquid stream immixture of supplement improves abundant, chemical combination leaching efficiency
It is very high；By producing cone ground swell stream by return tube after collection liquid stream, prevent material from depositing and block especially convenient, reliable, efficient；Tail
