Description
Technical field
The present invention relates to acid mist processing technology field, particularly relate to a kind of electro bath-lid that the acid mist produced in wet smelting process is prevented and treated.
Background technology
In the non-ferrous metal wet method smelting process such as copper, zinc, cobalt, nickel, lead, the mixed weak acids solution of general splendid attire sulfuric acid or sulfuric acid and hydrochloric acid in electrolyzer, working temperature is within the scope of 40 ~ 70 DEG C.In electrolyzer operational process, acid electrolyte can evaporate in a large number from uncovered electrolyzer.In addition, in the electrolytic deposition process of the metal such as copper, cobalt, while negative electrode separates out high purity metal, anode also can produce a certain amount of oxygen, chlorine etc. respectively.The gas that these reactions produce can adhere to acid drop effusion liquid level, and forms acid mist in atmosphere together with the electrolytic solution evaporated.A large amount of acid mist spreads in workshop, not only to the steel design of factory building and equipment, there is deep-etching effect, plant operations environmental abnormality also can be caused severe, and grievous injury producers' is healthy, and therefore acid mist problem has become one of the difficult problem of environmental protection of puzzlement hydrometallurgy industry development.
At present, the acid mist prevention and treatment method that domestic and international non-ferrous metal hydrometallurgy industry adopts can be divided into four large classes:
One, cover one deck bead or some parallel with cathode-anode plate long rods in electrolyte surface, its material can be glass, wood, rubber or plastics.The principle that it realizes is subject to the obstruction of coverture when being the acid solution effusion liquid level that ascending gas is carried secretly, collide and return liquid level, thus reduce acid mist escaped quantity.The method is simple to operate, and input cost is little, but poor to acid mist inhibition, does not eliminate the harm of operator and equipment.In addition, negative plate is close to by floating bead or long rod, and easily make metal refining produce broken edge, subsequent product has to pass through the reduction operation of broken edge, thus increases labour intensity.
Two, acid fog inhibitor is thrown in the electrolytic solution.Acid fog inhibitor mostly is the excellent special surface promoting agent of chemical stability, and it can reduce the surface tension of electrolytic solution, and forms foam layer fine and close continuously in electrolyte surface, stops acid solution effusion to a certain extent.The method is better to the inhibition of acid solution, but needs to throw in continuously, and running cost is high, thus large-scale application is restricted.In addition, although acid fog inhibitor can play good restraining effect to the volatilization of electrolytic solution, but the effusion of the obnoxious flavour such as chlorine, ammonia that some electrolytic reactions can not be stoped to produce, these obnoxious flavoures are overflowed by foam layer, can work the mischief to workshop condition and personnel health.
Three, on electrolyzer, acidproof oilcloth is covered.Cover the method for acidproof oilcloth in cell surface, can effectively stop acid mist to evaporate into workshop condition.But this method thoroughly can not eliminate the impact of acid mist on production environment, when plant working needs to raise oilcloth, the gentle cognition of acid mist be gathered under oilcloth escapes into workshop condition instantaneously.
Four, mounting groove lid on electrolyzer.At present, several hydrometallurgy enterprises have employed the method, and the electro bath-lid of application is the uncovered dome structure in bottom surface, with some stiffening webs on individual layer lid.This electro bath-lid is placed in cell wall, being abdicated anode and cathode rod position, directly not contacting with anode and cathode rod bottom groove lid by offering groove.Objectively, the effect of groove lid structural prevention and cure acid mist is best, not only can collect volatilization acid mist, is also convenient to configure with exhausting system use, acid mist is pumped out job shop and focuses on.In addition, groove lid does not contact with subsurface cathode-anode plate with electrolytic solution, can not affect the quality of product in electrolyzer.
But, circular arc inverted draw cut lid structure comes with some shortcomings: the exhausting arm that 1) in groove lid, nothing runs through, only be provided with suction opening in groove lid one end, cause that the acid mist pump drainage in whole electrolysis liquid surface overhead is uneven, pump drainage efficiency is low, still have most of acid mist from the effusion of lid end groove.2) circular arc inverted draw cut lid structural table area is large, the lid height of groove structure design is higher, for improving dome lid intensity, additionally some stiffening webs are set up again, make under material and the constant prerequisite of wall thickness, lid quality is very heavy, manually lift unload extremely inconvenient, need to coordinate overhead traveling crane to use, the potroom that therefore some automatization levels are not too high is at home difficult to be widely applied.3) when carrying out inspection short circuit and rinsing the operations such as bus, necessary frequent mobile circular arc inverted draw cut lid, labour intensity is large.
Summary of the invention
The object of the invention is to overcome the defect that existing domestic and international technology exists, and provide a kind of and effectively can prevent and treat the acid mist that produces in wet smelting process and intensity is high, quality is light, manually lifts and unloads easy electro bath-lid.
The present invention is realized by following technical scheme: a kind of electro bath-lid preventing and treating acid mist, and described electro bath-lid is rectangular parallelepiped, and it has long and short sidewall and top board, and the internal surface of described rectangular parallelepiped is provided with a reticular supporting structure; This reticular supporting structure comprises the exhausting arm arranged along described rectangular parallelepiped longitudinal cenlerline and the stiffening web of equidistantly arranging in these exhausting arm both sides; The two side of described exhausting arm has exhausting hole; The short sidewall of described rectangular parallelepiped has hole, this hole and described exhausting arm through.
The long and short sidewall of described rectangular parallelepiped, exhausting arm is rectangular pipe structure with stiffening web and it is highly consistent.
The short sidewall of described rectangular parallelepiped is equipped with to lift and unloads handle, this is lifted and unloads handle is groove structure.
Compared with the electro bath-lid structure of existing control acid mist, the present invention has following significant advantage:
One, reasonable in design of the present invention, intensity is high.Electro bath-lid adopts rectangular structure, so just optimizes cover body structure, and under material and the constant prerequisite of wall thickness, intensity strengthens greatly, improves the durability of lid.Meanwhile, rectangular structure can realize worker stands and stand in and caping directly carries out inspection short circuit and rinse bus operation, and deduction and exemption groove lid is lifted and unloaded number of times, reduces labour intensity.In addition, the sidewall of rectangular pipe structure and reticular supporting structure make lid intensity greatly improve, without the need to setting up stiffening web on lid.It is dual-purpose that the exhausting arms run of rectangle achieves a pipe, while pump drainage acid mist, also plays support enhancement to lid.
Two, quality of the present invention is light, and easy manually lifting is unloaded.Groove lid top panel is the slab construction that surface-area is less by arc structure transition, and groove lid is directly positioned on anode and cathode rod, no longer offers the groove abdicating anode and cathode rod, reduces groove lid height.Improved by these two aspects, groove lid weight significantly alleviates.When carrying out groove etc. and must removing the operation of groove lid, be easy to realize manually lifting unloading, thus reduce level is required to the automatization of enterprise, be more conducive to by large-scale application.
Three, the pump drainage efficiency of the present invention to acid mist is high, can realize the thorough control to acid mist.Borehole structure design is opened in the exhausting arm longitudinally run through in groove lid and both sides, and can meet the even pump drainage of electrolysis liquid surface overhead acid mist, acid mist pump drainage efficiency is high, thus thoroughly suppresses acid mist effusion.
