Lead Paste Desulfurization Reactor For Lead Smelting And Refining

This reactor adopts a reinforced industrial anti-corrosion structure, with diversified lining material options to adapt to different chemical reagent working scenarios. The thickened outer shell effectively resists mechanical impact from continuous slurry feeding. The specialized anti-corrosion inner lining withstands long-term erosion from lead paste mixtures and desulfurization agents, completely avoiding tank corrosion and material leakage caused by chemical medium erosion. All connection joints are reinforced with intensive welding and sealing technology to enhance overall airtightness, preventing slurry overflow and harmful volatile gas leakage during continuous batch production. Excellent structural stability prolongs equipment service life and minimizes daily component replacement costs for production workshops.

Fitted with a high-torque low-speed stirring unit and optimized impeller structure, the equipment realizes full-range mixing of lead paste slurry, clean water and desulfurization reagents inside the tank. It thoroughly eliminates bottom sediment accumulation and localized insufficient reaction problems, ensuring full contact between lead paste particles and chemical agents for stable and consistent desulfurization efficiency. The stirring system maintains a high chemical conversion rate during long-term batch cyclic production. All driving parts adopt professional dust-proof and moisture-proof protection design, perfectly adapting to the humid and dusty working environment of battery recycling workshops. It greatly reduces equipment failure risks caused by slurry splashing and guarantees stable, uninterrupted long-term operation.

The reactor is equipped with an automatic quantitative reagent feeding system, supporting precise and stable desulfurizer delivery. The built-in PLC intelligent control system monitors real-time pH value, reaction temperature and liquid level data inside the tank, automatically adjusting reagent dosage and stirring duration according to actual slurry conditions. This intelligent regulation eliminates reaction instability caused by manual feeding errors. Operators can check full-process operating data through the touch-screen human-machine interface, with all historical operation records stored for complete production traceability. The intelligent design simplifies on-site operation procedures, reduces reliance on skilled operators, and ensures uniform reaction quality for large-scale continuous recycling production.

Capable of high-precision sulfur removal for waste lead paste materials, the equipment drastically reduces the sulfur proportion of raw materials after treatment. When processed in subsequent rotary furnace smelting procedures, the desulfurized materials greatly inhibit sulfur dioxide generation. It effectively reduces the load of flue gas dedusting and absorption systems, lowering the daily operating and maintenance costs of environmental protection equipment. Meanwhile, optimized material composition improves the melting performance of lead raw materials, effectively increasing lead metal recovery rate and reducing smelting slag output. It creates substantial economic benefits and improves overall production efficiency for lead recycling factories.

Adopting a scientific modular layout, the equipment features independent structures for the main reaction tank, stirring assembly, dosing pipelines and detection sensors, facilitating convenient container transportation and fast on-site installation for overseas projects. Faulty components can be inspected and replaced individually without overall tank disassembly, greatly simplifying maintenance work. Reserved manholes and observation windows support regular internal cleaning and equipment inspection to ensure stable reaction efficiency. Standardized pipeline interfaces enable quick docking with upstream crushing equipment and downstream filter press devices, shortening equipment commissioning cycles and reducing long-term daily maintenance workload.
