Process of crushing and sorting waste lead-acid batteries
Complete set of equipment for pre desulfurization of lead paste and comprehensive utilization of by-products

This device is used for desulfurization treatment of lead paste separated from lead-acid batteries. The process includes:

The lead paste enters the pre desulfurization reaction tank A, and desulfurizer (ammonium bicarbonate) is added. At the same time, the mixed lead paste slurry in the tank is subjected to forced desulfurization before returning to the pre desulfurization tank. After the reaction is completed, a filter press is used for solid-liquid separation, and the filter cake (desulfurization lead paste) enters the smelting system; The filtrate (desulfurization filtrate A) enters filtrate tank A. The filtrate A is used as the reaction medium and enters the pre desulfurization reaction tank B. Lead paste and ammonium bicarbonate are added for desulfurization reaction, and the mixed lead paste slurry in the tank is subjected to forced desulfurization before returning to the pre desulfurization tank. After the reaction is completed, a filter press is used for solid-liquid separation, and the filter cake (desulfurization lead paste) enters the smelting system; Filtrate B (desulfurization filtrate B) enters filtrate tank B. The filtrate B (ammonium sulfate) enters the ammonium sulfate purification system.

B. Lead paste sodium method pre desulfurization equipment

This device is designed for desulfurization treatment of lead sludge obtained from the crushing and separation of lead-acid batteries. The process includes:

Lead mud enters the pre desulfurization tank, reacts with desulfurizer (sodium carbonate), and is thoroughly stirred. At the same time, the mixed lead paste slurry in the tank is subjected to forced desulfurization before returning to the pre desulfurization tank. After the reaction is completed, a filter press is used for solid-liquid separation, and the filter cake (desulfurization lead paste) enters the smelting system; The filtrate (sodium carbonate) enters the filtrate tank.

· Sulfur content of lead paste after desulfurization ＜ 1%

Sodium desulfurization method
1.The pre desulfurized filtrate is sent to the purified raw material storage tank.
2.The PH value of the filtrate is adjusted in the reaction tank, and purification reagent is added.
3.After passing the inspection, store in the liquid storage tank.

A.Ammonium sulfate solution:25-35%, The heavy metal content in the treated solution is less than 10PPM.

C.Sulfate solution purification treatment equipment
Main process flow
Evolutionary treatment of heavy metal ions and other impurities in the sulfate solution generated by pre desulfurization.  

Purification treatment process
The purified sulfate solution is processed by MVR to generate sulfate products.
The condensed water generated by M VR is returned to the desulfurization process for recycling or (and) discharged after being treated and qualified.

After complete dehydration through drying equipment, high-purity sulfate products are obtained and sold.


Drying process
D. Sulfate crystallization drying equipment
Evaporating crystallization
MVR process
After the mixture enters the high-temperature melting furnace, the reduced lead enters the ingot hopper, and the lead slag is discharged into the lead slag hopper. The flue gas generated during the smelting process is treated and discharged in compliance with standards. The equipment includes precise proportioning, automatic feeding, combustion system, furnace body, cooling system, and exhaust gas dust removal and desulfurization treatment.
