Description
Technical field
The utility model relates to a kind of device for the treatment of being derived from waste gas source, that include acid mist that forms acid mist, is specifically related to such device, and it comprises: gas scrubber, and it is arranged to the waste gas that receives removal acid mist to be cleaned; Mist eliminator, after its flow direction along gas is arranged at described gas scrubber, to remove drop from gas scrubber receiver gases and from gas; The fan of air-flow is provided; And the dry gas cleaning is delivered to the chimney to ambient air.。
Background technology
In the time reclaiming such as the metal of copper from sulfide ore, use sulfuric acid that copper is leached to form copper-bath, by sedimentation from described electrolysis of solutions deposited copper to obtain copper metal.In electrolysis, the negative electrode of making by lead anode with by stainless steel immerses and includes in the electrolytic bath of copper sulfate/sulphuric acid soln.Electric current flows to negative electrode from anode, causes electrochemical reaction, thus metallic copper is deposited on the surface of negative electrode.Meanwhile, releasing oxygen on the surface of anode.The bubble that oxygen forms discharges and rises through electrolytic solution from anode.On the free surface of electrolytic solution, bubble break and air volume above electrolytic solution in produce acid mist, described acid mist is the mist of the acid droplet that suspends.Acid mist causes the significant Health hazard to user.Therefore, electrolytic deposition equipment has acid mist to reclaim and treatment unit.Conventionally cover electrolyzer 7 by cover 8 (referring to Fig. 1), cover 8 is for collecting acid mist and guiding it into atmosphere via acid mist treatment device.
The schematically illustrated typical known acid mist treatment device of Fig. 1.Described acid mist treatment device comprises gas scrubber 1, and gas scrubber 1 moves and receives from electrolytic deposition EW waste gas that aspirated, that include acid mist with wet scrubbing principle.Gas scrubber 1 is removed acid mist from gas.The flow direction along gas is provided with mist eliminator 2 after gas scrubber 1.From mist eliminator 2, gas is passed fan 3 and aspirates and be drawn towards chimney 4, and the gas cleaning leaves chimney 4 entered environment air.Fan 3 provides negative pressure to pass through gas scrubber 1 and mist eliminator 2 with intake-gas.In addition, after fan 3, before chimney 4, be provided with choke valve 6 along the flow direction of gas.
From for example Sabdiel Mella of the SAME company limited of text WO2009/025837A1 and Chile openly, Rodrigo Villarroel, such acid mist treatment device known in the article " Copper electrowinning in the absence of acid mist:six years of industrial application " of Alejandro Lillo.
Problem is, the fan after the flow direction of gas is arranged at gas scrubber moves as suction fan, and it is not to move in the best way and air-flow may change intensely and very suddenly thus.Therefore need choke valve, this has increased cost of investment.Described choke valve also has the impact of the energy expenditure of the CD-ROM drive motor that increases fan.Fan also needs effective CD-ROM drive motor, and this has increased cost of investment.Another problem is, gas scrubber moves under negative pressure, and wherein negative pressure contributes to evaporation and therefore damaged the cleaning efficiency of gas scrubber.In addition, can not clean fan for water during use, because wash-down water will directly leave from chimney.For current system, for clean fan, must make it stop cleaning.
Summary of the invention
The purpose of this utility model is to make up defect mentioned above.
Especially, the purpose of this utility model is the improved device of open one, and it is more favourable than current device aspect investment and running cost.
Another object of the present utility model is open a kind of device, and wherein gas scrubber can move under slight positive pressure.
Another object of the present utility model is open a kind of device, and wherein without stopping fan, the clean fan of water is possible during use.
A kind of device for the treatment of being derived from waste gas source, that include acid mist that forms acid mist is provided, and described device comprises: gas scrubber, and it is arranged to the waste gas that receives removal acid mist to be cleaned; Mist eliminator, after its flow direction along gas is arranged at described gas scrubber, to remove drop from gas scrubber receiver gases and from gas; Provide the fan of air-flow, before fan is arranged at gas scrubber along the flow direction of gas; And the dry gas cleaning is delivered to the chimney to ambient air, and it is characterized in that, fan is provided with water spray cleaning device to clean during use fan.According to the utility model, before fan is arranged at gas scrubber along the flow direction of gas, gas scrubber moves under positive pressure a little thus.
In an embodiment of described device, the source that forms acid mist is electrolytic deposition equipment.The other parts of technique also may produce acid mist.
In an embodiment of described device, gas scrubber is the gas washer that gas to be cleaned is contacted with washing soln.
In an embodiment of described device, mist eliminator is cyclone type, multi-layer type or grid type or their any combination.
In an embodiment of described device, fan is variable speed fan.
Brief description of the drawings
In following part, with reference to accompanying drawing illustrates embodiment by way of example, the utility model is specifically described, wherein:
The schematically illustrated prior art acid mist treatment device of Fig. 1; And
Fig. 2 is schematically illustrated according to device described in the utility model embodiment.
Embodiment
Fig. 2 illustrates for the treatment of the device of waste gas that includes the acid mist producing in electrolytic deposition EW.Described device comprises gas scrubber 1, and it is arranged to receive treats waste gas cleaned removal acid mist, that include acid mist.Provide before the fan 3 of air-flow is arranged at gas scrubber 1 along the flow direction of gas, gas scrubber moves under slight positive pressure thus.Fan 3 is arranged at before gas scrubber and has the effect that makes gas scrubber use electric energy still less, because removed unnecessary choke valve and realized identical washability with less fan motor.In an example embodiment, with respect to corresponding known scheme, cost of investment reduced 10% and running cost reduced 20%.Reduce the air-flow by gas scrubber, because gas scrubber moves with slight positive pressure, instead of the slight negative pressure of the scheme using in the prior art of Fig. 1.In one embodiment, the difference between air flow value to 17% (3000m.a.s.l.), means that cost of investment has reduced 25% between 10.5% (0m.a.s.l.).It is possible between the usage period of fan 3, cleaning by water.In one embodiment, this means that running cost has compared with prior art reduced 15%.System with positive pressure (even with slight positive pressure) operation contributes to condense and has therefore improved washability.With further reference to Fig. 2, is mist eliminator 2 along the flow direction of gas after gas scrubber, to remove drop from gas scrubber receiver gases and from gas.Described device further comprises chimney 4, so that the dry gas cleaning is delivered to surrounding space.
Fan 3 is provided with water spray cleaning device 5 to clean during use fan.Fan 3 can be constant speed or variable speed fan.
Gas scrubber 1 is preferably and makes gas to be cleaned and the gas washer contacting such as the washing soln of water.
Mist eliminator 2 can be cyclone type, multi-layer type or grid type or their any combination.
The utility model is not restricted to its example of embodiment mentioned above; On the contrary, in the scope of invention thought defined by the claims, can there are a lot of distortion.
