Description

Technical Field

[0001] The present invention belongs to the technical field of smoke treatment devices, and in particular relates to a lead smoke treatment device. Background Art

[0002] Lead-acid batteries, with their excellent performance-price ratio, are widely used in backup power, energy storage, and power energy. Although lithium batteries have made significant progress in recent years, their high price and safety requirements mean they will likely struggle to dislodge their dominant position in the secondary battery market for some time. The molten lead provided during the production process requires the use of a lead dissolving pot.

[0003] However, in the prior art, most lead fume treatment devices adopt a single-cavity structure, which has low treatment efficiency and cannot achieve alternating treatment of acid and alkali solutions, resulting in incomplete lead fume purification. Summary of the Invention

[0004] The purpose of the present invention is to provide a lead fume treatment device, which realizes the synchronous partitioning treatment of alkaline solution and dilute acetic acid solution through dual independent treatment chambers separated by partitions and alternating blocking design, significantly improves the lead fume purification efficiency, and solves the problems raised by the existing background technology.
