Description
One. technical field
The present invention relates to hydrometallurgy electrowinning plant and method, especially a kind of plumbum anode composite board winning cell and acidity mist inhibition method thereof are particularly suitable for copper mine and select smelting factory to use.
Two. background technology
At present, the chloride plate of the hydrometallurgy electrowinning plant that adopts is to connect lead anode by current conducting rod both at home and abroad, very easily produces acid mist in electrolytic deposition process, in electrolytic deposition process, following electrode reaction takes place on the anode:
2H
2O → 4H
++ O
2↑+4e or 2OH
-+ 2e → 2H
++ O
2↑
During electrode reaction, small oxygen is at first separated out on pole plate, and attaches the surface of metal polar plate under liquid level, after gas dissolving enters solution and reaches capacity, just gathers into bubble in the metallic surface.Be subjected to metal interface tensile effect under the liquid level, bubble rests on the metallic surface.When bubble increases to the about 0.3mm of diameter when above gradually, its buoyancy surpasses interfacial tension, and the bubble disengagement metallic surface is to come-up.Bubble obtains kinetic energy in floating-upward process, take solution when breaking through liquid level out of, meets cold back explosion in air, forms droplet, fills the air everywhere.So, the oxygen that electrolytic deposition process forms can be carried a large amount of acid mists secretly and come out in the effusion process, cause that sulfuric acid and sulfur dioxide concentration substantially exceed environmental protection standard in the low vacancy pollution electrodeposition groove face air, both cause low vacancy pollution in the factory building, be unfavorable for workman's physical and mental health, increased the consumption of sour consumption and additive again, the oxygen of separating out then can cause cathode copper to produce pore if be adsorbed on the negative electrode, influences the visual appearance of finished product copper.
For addressing these problems, there is more producer to adopt the mechanical exhaust method to handle, promptly after acid mist produces, strengthen the ventilation in the factory building, reduce the concentration of acid mist or on solution pool, install gas skirt additional, the gas sampling of band acid mist is got up, extract high altitude discharge out with blower fan again or carry out discharging behind the acid-base neutralisation, but this method belongs to treatment process afterwards, promptly acid mist is handled after producing again, can not begin from the source to administer, and can not reduce the consumption of acid consumption and additive.Also have minority producer to adopt cladding process to handle, promptly one is solution surface plastic covering bead or PP bead in cell body, the 2nd, and in solution, add additive and form tectum, in the hope of stoping filling the air of acid mist.The former can increase the resistance of micro-bubble come-up and make its volume increase, reduce its specific surface area, thereby reduces acid mist, but it is undesirable to suppress effect, and bead sandwiches the labor capacity that can greatly increase operator in the hanger of negative electrode product; The latter can increase the resistance of micro-bubble come-up and reduce its specific surface area, thereby minimizing acid mist, but for keeping stable tectum to need often to add additive, usage quantity is big, price is higher, causes production cost to increase, and behind the life-time service, additive causes accumulation in electric effusion, can cause detrimentally affect by the anticathode copper mass.
Three. summary of the invention
