Battery changes into acid mist cleaning system and acid mist purifier thereof
Technical field
The present invention relates to battery production equipment technical field, particularly a kind of battery changes into acid mist cleaning system and acid mist purifier thereof.
Background technology
In the manufacturing process of battery; Need through certain charge and discharge system the inner both positive and negative polarity substance activating of pole plate; Change state-of-charge into, removal of contamination improves the combination property such as charge-discharge performance and self discharge, storage of battery; This chemical reaction process is called the chemical synthesis technology process, and the chemical synthesis technology process is one of important procedure of battery production.
Accumulator plate changes into outward in the technical process, and positive and negative pole plate generates alkali formula brown lead oxide and spongy lead with dilute sulfuric acid through redox reaction under galvanic effect when charging, and chemical equation is following:
Negative pole: PbSO
4+ H
++ 2e → Pb+HSO
4 -
Anodal: PbSO
4+ 2H
2O → Pb O
2+ 3H
++ HSO
4 -+ 2e
Be not difficult to find out by above-mentioned reactional equation: along with constantly carrying out of charging process, when discharging with a large amount of heats.Hydrone in the electrolyte constantly is consumed, H SO
4 -With H
+Be combined into H
2SO
4, 2H
+Then combine to generate H
2, the acid solution surface evaporation, sulfuric acid molecule gets into air, generates the sulfuric acid droplet with airborne hydrogenesis.
This acid mist is must supervene in the battery production process, and the acid mist corrosion strength is strong, and toxicity is big, and the acid mist that loss goes out be if arbitrarily discharging will not be collected, and can cause that acid mist fills the air in the air of workplace, is detrimental to health; Corrosion plant and equipment and precision instrument make ageing equipment, cause the loss of production; Can cause atmosphere pollution again after entering atmosphere, crops and other vegeto-animal existence are brought harmful effect, also can cause building is damaged, bring endless trouble.
In the prior art; Acid mist collection system is generally adopted in collection to acid mist, and the acid mist that need not careless and sloppy discharging is imported induced duct, adopts powerful air inducing that acid mist is introduced in the clarifier then; React through the filtration of filter and with alkaline aqueous solution, to reach the purpose of purification.But the flow velocity of acid mist in the filter of present clarifier is very fast, makes and can't neutralization reaction completely take place with alkaline aqueous solution, causes the part acid mist to enter in the middle of the atmosphere.
