Description
Technical field
The present invention relates to the acid mist processing technology field, relate in particular to a kind of electro bath-lid that the acid mist that produces in the wet smelting process is prevented and treated.
Background technology
In 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 the electrolyzer, working temperature is in 40 ~ 70 ℃ of scopes.In the electrolyzer operational process, acid electrolyte can evaporate from open electrolyzer in a large number.In addition, in the electrolytic deposition process of metals such as copper, cobalt, when negative electrode was separated 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 in air, forms acid mist with the electrolytic solution that evaporates.A large amount of acid mists spread in the workshop; Not only steel design and the equipment to factory building has the deep-etching effect; Also can cause the plant operations environmental abnormality abominable, the heavy damage producers' is healthy, so the acid mist problem has become one of environmental protection difficult problem of puzzlement hydrometallurgy industry development.
At present, the acid mist prevention and treatment method of non-ferrous metal hydrometallurgy industry employing both at home and abroad can be divided into four big types:
One, cover one deck bead or the some long rods parallel with cathode-anode plate in electrolyte surface, its material can be glass, wood, rubber or plastics.The principle that its is realized is to receive obducent obstruction when making the acid solution effusion liquid level that ascending gas carries secretly, bumps and returns liquid level, thereby reduce the acid mist escaped quantity.This method is simple to operate, and input cost is little, but acid mist is suppressed weak effect, and the harm of operator and equipment is not eliminated.In addition, buoyant bead or long rod are close to negative plate, are prone to make metal refining to produce broken edge, and subsequent product must pass through the reduction operation of broken edge, thereby increase labour intensity.
Two, in electrolytic solution, throw in acid fog inhibitor.Mostly acid fog inhibitor is the special surface promoting agent that chemicalstability is good, and it can reduce the surface tension of electrolytic solution, and forms the foam layer of continuous densification in electrolyte surface, stops acid solution to be overflowed to a certain extent.This method is better to the inhibition effect of acid solution, but needs to throw in continuously, and running cost is high, thereby large-scale application is restricted.In addition; Though acid fog inhibitor can play the good restraining effect to the volatilization of electrolytic solution; But can not stop the effusion of obnoxious flavoures such as chlorine that some electrolytic reactions produce, ammonia, these obnoxious flavoures are overflowed through foam layer, can work the mischief to workshop condition and personnel health.
Three, on electrolyzer, cover acidproof oilcloth.Cover the method for acidproof oilcloth in cell surface, can effectively stop acid mist to evaporate into workshop condition.But this method can not thoroughly be eliminated the influence of acid mist to production environment, and when plant working need be raised oilcloth, the gentle cognition of the acid mist moment that accumulates under the oilcloth escaped into workshop condition.
Four, mounting groove lid on electrolyzer.At present, hydrometallurgy enterprise of several family has adopted this method, and the electro bath-lid of application is the open dome structure in bottom surface, has plurality of strengthening ribs on the individual layer lid.This electro bath-lid is placed on the cell wall, and groove lid bottom is abdicated anode and cathode rod position through offering groove, does not directly contact with the anode and cathode rod.Objectively, the effect of groove lid structure control acid mist is best, not only can collect the volatilization acid mist, also is convenient to use with the exhausting system configuration, the acid mist pump drainage is gone out job shop focus on.In addition, the groove lid does not contact with subsurface cathode-anode plate with electrolytic solution, can not influence the quality of product in the electrolyzer.
But; Circular arc inverted draw cut lid structure comes with some shortcomings: 1) do not have the exhausting arm that runs through in the groove lid; Only be provided with suction opening, cause that the overhead acid mist pump drainage of whole electrolysis liquid surface is inhomogeneous, pump drainage efficient is low, still have most of acid mist to overflow from lid end groove at groove Gai Yiduan.2) circular arc inverted draw cut lid structural table area is big, and the lid height of groove structure design is higher, for improving dome lid intensity; Extraly some stiffening webs have been set up again; Make that the lid quality is very heavy under the constant prerequisite of material and wall thickness, manual work lift unload extremely inconvenient; Need to cooperate overhead traveling crane to use, the potroom that therefore some automatization levels are not too high at home is difficult to applied.3) when checking that short circuit and flushing bus etc. are operated, necessary frequent mobile circular arc inverted draw cut lid, labour intensity is big.
Summary of the invention
The objective of the invention is to overcome the defective that existing technology both at home and abroad exists, and provide a kind of acid mist and intensity of producing in the wet smelting process of effectively preventing and treating high, light weight, manual work is lifted and is unloaded easy electro bath-lid.
The present invention realizes through following technical scheme: a kind of electro bath-lid of preventing and treating acid mist, said electro bath-lid are rectangular parallelepiped, and it has long and short sidewall and top board, and the internal surface of said rectangular parallelepiped is provided with a mesh-supported structure; This mesh-supported structure comprises along the exhausting arm of said rectangular parallelepiped longitudinal cenlerline setting and the stiffening web of equidistantly arranging in these exhausting arm both sides; Have the exhausting hole on the two side of said exhausting arm; Have the hole on the short sidewall of said rectangular parallelepiped, this hole and said exhausting arm connect.
The long and short sidewall of said rectangular parallelepiped, exhausting arm and stiffening web are the rectangular pipe structure and it is highly consistent.
Be equipped with to lift on the short sidewall of said rectangular parallelepiped and unload handle, this is lifted and unloads handle is groove structure.
Compare 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, has so just optimized cover body structure, and under the constant prerequisite of material and wall thickness, intensity strengthens greatly, has improved the durability of lid.Simultaneously, rectangular structure can realize that the workman stand in and directly check short circuit and flushing bus operation on the caping that deduction and exemption groove lid is lifted and unloaded number of times, has reduced labour intensity.In addition, the sidewall of rectangular pipe structure and mesh-supported structure improve lid intensity greatly, need not on lid, to set up stiffening web.The design of orthogonal exhausting arm has realized that a pipe is dual-purpose, in the pump drainage acid mist, also lid is played the support enhancement.
Two, light weight of the present invention, easy manual work is lifted and is unloaded.The groove lid top panel is the less slab construction of surface-area by the arc structure transition, and the groove lid directly is positioned on the anode and cathode rod, no longer offers the groove of abdicating the anode and cathode rod, has reduced groove lid height.Improve through this two aspect, groove lid weight alleviates significantly.When going out groove etc. and must remove the operation of groove lid, be easy to realize that manual work is lifted unloads, thereby the robotization that reduces enterprise requires level, is more conducive to by large-scale application.
Three, the present invention is high to the pump drainage efficient of acid mist, can realize the thorough control to acid mist.The borehole structure design is opened in exhausting arm that vertically runs through in the groove lid and both sides, can satisfy the even pump drainage of the overhead acid mist of electrolysis liquid surface, and acid mist pump drainage efficient is high, overflows thereby thoroughly suppress acid mist.
