Abstract
The present invention relates to a kind of manner of cleaning up of aiutage, comprise the following steps：The first step：The waste water or electrolysis waste solution of the sulfuric acid containing finite concentration are connected to the top of aiutage by pipeline；Second step：Waste water or electrolysis waste solution are sprayed from top to bottom at the top of aiutage；3rd step：Fouling with aiutage inwall is reacted, and fouling is shedded into retort from inwall.Manner of cleaning up of the present invention have the advantages that quickly, effectively, safety.
Description
Technical field
The present invention relates to a kind of mode of aiutage, belong to smelting field of nonferrous metal.
Background technology
In conventional wet lay zinc metallurgy enterprise, general technological process is：Sulfuric acid-calcining leaching-middle supernatant purification-new
The techniques such as liquid electrolysis-casting mold, wherein in the technical process such as leaching in calcining, the purification of middle supernatant, in order to by the gas in retort
Body discharges factory building, there is the exhaust apparatus such as aiutage in retort.In aiutage exhaust process, part calcining, zinc powder etc.
Aiutage can together be entered with steam, in the one layer of fouling of formation of aiutage inwall, influence aiutage is unimpeded.Exhaust general at present
Cylinder manner of cleaning up shakes aiutage to shake device in aiutage increase, by timing makes fouling be separated with inwall, the method increase
The stress of aiutage, causes exhaust pipe structure requirement complicated, can bear to shake device and shakes, simultaneously because aiutage height compared with
Height, easily occurs security incident when shaking for a long time, and device is shaken in addition, and to shake effect not good, and fouling thickness is not easily cleaned.
The content of the invention
The mode of aiutage can be cleared up effectively, quickly, safely in view of the above problems, the present invention provides a kind of.
The present invention mainly uses different dense in the electrolysis waste solution produced in the waste water or electrolytic process of workshop generation
The fouling of the sulfuric acid of degree and aiutage inwall is reacted, and fouling is departed from inwall, reaches the purpose of cleaning aiutage, mainly
Step is as follows：
The first step：The waste water or electrolysis waste solution of the sulfuric acid containing finite concentration are connected to the top of aiutage by pipeline；
Second step：The waste water or electrolysis waste solution of the sulfuric acid containing finite concentration are sprayed from top to bottom at the top of aiutage；
3rd step：The fouling of the waste water or electrolysis waste solution of the sulfuric acid containing finite concentration and aiutage inwall is reacted, and fouling is from inwall
Shed into retort, reach the purpose of cleaning aiutage.
The reaction of generation is as follows：
ZnO+H2SO4=ZnSO4+H2O
Or Zn+H2SO4=ZnSO4+H2
The positive effect of the present invention is：By sulfuric acid containing finite concentration（≥20g/l）Waste water or electrolysis waste solution and aiutage
Encrustation directly reacts, it is to avoid extra installation shakes device and shakes off encrustation, alleviates the load of aiutage, the row of extending
The service life of inflator；This invention can thoroughly effectively, fast and safely clear up aiutage, alleviate labor intensity；Can be according to row
The fouling condition adjustment waste water of cylinder inner wall or addition and the addition time of electrolysis waste solution.
Embodiment
The inventive method is further illustrated with reference to instantiation.
It is a kind of to clear up the mode of aiutage effectively, quickly, safely.The present invention mainly use workshop produce waste water or
The fouling of the sulfuric acid of various concentrations in the electrolysis waste solution produced in person's electrolytic process and aiutage inwall is reacted, and makes fouling
Depart from inwall, reach the purpose of cleaning aiutage, key step is as follows：
The first step：By sulfur-bearing acid concentration for 100-200g/L waste water or electrolysis waste solution by acid-proof pump and pipeline to arranging
The top of inflator；
Second step：Sulfur-bearing acid concentration is sprayed from top to bottom for 100-200g/L waste water or electrolysis waste solution at the top of aiutage
Drench；
3rd step：Sulfur-bearing acid concentration is reacted for 100-200g/L waste water or electrolysis waste solution with the fouling of aiutage inwall, knot
Dirt is shedded into retort from inwall, reaches the purpose of cleaning aiutage.
The present invention passes through sulfuric acid containing finite concentration（≥20g/l）Waste water or electrolysis waste solution and aiutage encrustation it is straight
It is reversed should, it is to avoid extra installation shakes device and shakes off encrustation, alleviates the load of aiutage, extends the use of aiutage
Life-span；This invention can thoroughly effectively, fast and safely clear up aiutage, alleviate labor intensity；Can be according to aiutage inwall
Fouling condition adjusts the addition of waste water or electrolysis waste solution and adds the time.Oxidation of the present invention suitable for zinc oxide system
The aiutage cleaning of the retort such as zinc neutrality extract technology, sour supernatant replacing process.
Above example is only the preferred embodiment of the present invention, for industry technical staff, in the processing of the present invention
Under the premise of principle, some improvement made also should be regarded as protection scope of the present invention.
