Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a utilization system for lead sulfate recovery. Background Art

[0002] During the process of acid drenching of battery plates, about 3% or less of the lead paste on the plate surface and the frame is washed away with the acid drenching. These washed-away lead sludges will generate a large amount of lead sulfate due to being soaked in dilute sulfuric acid.

[0003] In the prior art, the common treatment method for lead sulfate is usually to place a recovery box at the acid drenching roller to collect the waste acid and the lead sludges washed away by the acid during the acid drenching process. Since the lead sludges are soaked in dilute sulfuric acid, the mixture of dilute sulfuric acid and lead sludges in the recovery box is placed at room temperature and undergoes long-term precipitation in the recovery box. The upper-layer acid drenching liquid will be pumped away by the operator at any time for the recycling of dilute sulfuric acid. After the first precipitation is completed, the lead sulfate generated on the same day is fished up with acid-resistant tools and then handed over to a waste recycling unit with the qualification to dispose of lead-containing waste materials for treatment.

[0004] The existing treatment method for lead sulfate has the following deficiencies:

[0005] 1) When using the physical precipitation method, there will be excess acidic liquid that can be recycled in the lead sludges, the recovery rate of the acid liquid is low, and the acid liquid cannot be well treated;

[0006] 2) The existing treatment method wastes a large amount of lead. The lead sludges and acid liquid cannot be well treated, which also causes great waste of resources and increases the production cost of the manufacturer;

[0007] 3) The mixture of dilute sulfuric acid and lead sludges undergoes long-term precipitation in the recovery box, and the formed precipitate is solid waste acid-drenched lead sludges. The solid waste acid-drenched lead sludges are hazardous solid wastes, which are very easy to pollute the environment, and when handed over to the waste recycling unit, it is easy to pollute the environment during the loading, unloading and transportation processes.
