Waste lead-acid battery recycling and smelting is a key link in resource circulation. However, the process releases high-concentration sulfur dioxide flue gas. Direct emission will not only pollute the air but also endanger human health. Flue gas desulfurization (FGD) technology is precisely the "purification guardian" in this environmental protection campaign.
The core logic of desulfurization is simple: use professional equipment to fully contact sulfur-containing flue gas with lime or limestone slurry, and convert toxic sulfur dioxide into harmless substances through chemical reactions. Today's mainstream processes adopt multi-layer flue gas neutralization design combined with rotary diversion structure, which enables more sufficient gas-liquid contact. The desulfurization efficiency can reach over 99.9%, easily meeting strict environmental emission standards.
What's more commendable is that recyclable by-products can be generated during the desulfurization process, realizing "turning waste into treasure". This technology not only solves the environmental problem of waste battery recycling but also injects green power into resource circulation, making every recycling activity a positive force for ecological protection.
