Abstract
The utility model relates to a nickel electrodeposition acid fog absorption device, and is characterized in that the device is a long strip type hood body with a lower opening fixed on a nickel electrolyte anode diaphragm frame. A cathode through rod rim is positioned at two sides of an anode hood, which completely covers an overall anode. The upper hood top of the hood body is vertically and centrally provided with a strip type anode plate insertion opening. The end of the upper hood top of the hood body is fixedly connected with a row of exhaust pipes. As a gas collection hood is arranged on the electrodeposition tank anode chamber of the utility model, the acid fog is sucked away by a pipeline before entering into the operation space. Compared with the tradition ventilation method, the acid fog absorption device has the advantages that the method is simple, the occupation space is smaller, the utilization rate of the space is high, the tank surface operation is not affected, the ventilation effect is good, etc.
Description
Technical field
The utility model relates to a kind of nickel electrodeposition acid mist absorption unit.
Background technology
Develop rapidly along with metallurgical technology, the electrowinning with insoluble anode technology has had very big development, because the electrodeposition technology has the incomparable advantage of a lot of soluble anode electrolysis: level of automation height, the little space availability ratio height of homopolarity interpole gap, direct yield height, labour intensity are low or the like, and the electrowinning with insoluble anode technology is replacing the soluble anode electrolysis tech gradually.What electrodeposition was used is insoluble anode, and anode does not dissolve, at anode H
2O loses electronics and generates oxygen and hydrogen ion, and oxygen overflows, and hydrogen ion is enrichment gradually, and the nickel ion in the solution obtains electronics and separates out electro deposited nickel on negative electrode.
The positive column hydrogen ion enrichment in process of production of sulfation electro deposited nickel refinery practice, it is the individual acid-respons of making, when anodic oxygen and steam overflow from liquid, bubble surface can be brought into a spot of acid in the air under the tension force effect, form acid mist, make the abominable unusually of operating environment change, steel-structure factory building and equipment are had very big corrodibility, reduce the life-span of plant and equipment simultaneously.
At present, adopt draft type to solve the environmental problem that the volatilization of groove face acid mist is caused usually, be difficult to make the electrodeposition operating environment to improve, operating environment and equipment are also existed disadvantageous effect.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, and a kind of nickel electrodeposition acid mist absorption unit that the effective collecting of the acid mist that produces in the electrolytic deposition process can be handled is provided.
The purpose of this utility model is achieved through the following technical solutions.
A kind of nickel electrodeposition acid mist absorption unit, it is characterized in that this device is one to be fixed on the long strip shape cover body of the lower open mouth on the nickel electrowinning anode barrier film frame, negative electrode bar Tam is in the both sides of anode cap, whole anode is covered fully, and cover top vertically has a bar shaped positive plate between two parties and inserts mouthful on cover body, the termination on the cover top vapor pipe that has been fixedly connected on cover body.
A kind of nickel electrodeposition acid mist absorption unit of the present utility model is characterized in that vapor pipe that the termination of going up the cover top of described cover body is fixedly connected compiles by flexible pipe to focus on.
In sulfuration electro deposited nickel refinery practice process, positive column H
2O loses electronics and generates oxygen and H
+, the acid concentration of positive column raises, and is to make acid-respons; And at negative electrode, nickel ion obtains electronics.The main reaction mechanism of electrolytic deposition process is as follows:
1. anodic reaction: H
2O-2e=1/20
2↑+2H
+
2. cathodic reaction: Ni
2++ 2e=Ni
When positive column oxygen overflows from liquid, a spot of acid can be brought in the air when bubble breaks, form acid mist.
The positive column produces acid mist, concentrates collecting through gas skirt, sends into the acid mist eluting column through blower fan and carries out the acid mist absorption with the nickelous carbonate supernatant liquor, and principle of absorption is as follows:
Na
2CO
3+H
2SO
4＝Na
2SO
4+CO
2↑+H
2O
A kind of nickel electrodeposition acid mist absorption unit of the present utility model after the nickel electrodeposition acid mist can being collected, through pipe influx, and then enters into and washes shower device, and the micro-nickel ion that is mingled with in the acid mist is reclaimed exhaust gas emission.Operating environment improves, and has avoided the corrosion of mill construction and equipment, simple in structure, easy for installation, acid mist collecting efficient height, the easy to operate spatial equipment of saving again.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
Embodiment
A kind of nickel electrodeposition acid mist absorption unit, it is characterized in that this device is one to be fixed on the long strip shape cover body 1 of the lower open mouth on the nickel electrowinning anode barrier film frame, negative electrode bar Tam is in the both sides of anode cap, whole anode is covered fully, and cover top vertically has a bar shaped positive plate between two parties and inserts mouthfuls 2 on cover body, the termination on the cover top vapor pipe 3 that has been fixedly connected on cover body; The vapor pipe that the termination of going up the cover top of described cover body is fixedly connected compiles by flexible pipe and focuses on.
Embodiment
In insoluble anode nickel refining technological process, each anolyte compartment of Winning cell is installed additional gas skirt cover, cover material adopts ABS, and color and luster is an oyster white, and proportion is 1/8 of steel, and solidity to corrosion is strong, and is simple in structure, easy for installation, do not influence the groove face operation again.Hose connection between gas skirt and the ventilator trunk with the d25 white polytetrafluoroethylpipe, when fan starting, present negative pressure in the cover, the accumulative acid mist through pipe-line transportation to washing the pouring tower, the tail gas of washing after the pouring effluxes, and the micro-nickel ion in the acid mist is trapped within the circulation fluid, and circulation fluid regularly returns production system.The electrodeposition site environment improves greatly, does not contain acid mist in the air.
