Abstract

The invention provides a lead sulfate waste desulfurization device and a lead sulfate waste desulfurization process thereof. The device comprises a desulfurization tank, a conversion tank, a carbonization tank, filters, a pump, a liquid storage groove and conveying pipes, wherein the desulfurization tank is connected with a first filter through a conveying pipe, a solution obtained after solid-liquid separation is conveyed into the conversion tank through a conveying pipe, the conversion tank is connected with a second filter through a conveying pipe, a solution obtained after solid-liquid separation is conveyed into the carbonization tank, and the molten liquid in the carbonization tank is pumped into the liquid storage groove through a pump and is to be transferred into the desulfurization tank so as to be recycled. According to the invention, solutions in a desulfurization tank, a conversion tank and a carbonization tank are circularly arranged, so that the reaction efficiency is effectively improved while the conveying pipe of the tank body is blocked due to slurry precipitation or scaling in the tank body is effectively reduced; and a carbonizing agent and organic phenolic substances are regenerated and recycled, so that the desulfurization cost is greatly reduced, the environmental pollution is effectively reduced, the production efficiency is effectively improved, and the desulfurization purpose is thoroughly achieved.

Description

technical field

[0001] The invention relates to waste lead-acid battery recycling technology, in particular to a lead sulfate waste desulfurization device and its technology. Background technique

[0002] A dismantling and recovery system for waste lead-acid batteries and a recovery and recovery system for hazardous lead waste have been built. The recovery and recovery system mainly deals with the lead paste produced by the dismantling system and the lead sludge and lead soot produced by other non-ferrous refineries. In addition to being rich in many valuable elements such as lead, copper, bismuth, tin, gold, and silver, such materials generally contain sulfur, which presents considerable technical and cost challenges to the processing of such materials. In order to solve this problem, ensure the full recovery efficiency of resources and the good economic benefits of enterprises.
