Embodiment 1

[0034] A waste lead-acid battery processing system, the system includes a crushing and sorting system 1, a drying system 2 connected to the crushing and sorting system through a grid conveying pipeline, and a lead melting pot 3 connected to the drying system 2 through a conveying pipeline; It also includes the smelting system 4 connected to the crushing and sorting system through the lead paste conveying pipeline, the lead scum removal system 5 connected to the smelting system 4 through the conveying pipeline, and the dust collection system connected to the lead scum removing system through the conveying pipeline. System 6, the dust collection system 6 communicates with the lead melting pot 3 through a delivery pipeline. Wherein said drying system is also communicated with hot air blower 202;

[0035] The system also includes a pretreatment system 7 before the crushing and sorting system, which pretreats the collected waste lead-acid batteries and then enters the crushing and ...

Embodiment 2

[0039] The process for treating waste lead-acid batteries by using the above-mentioned waste lead-acid batteries comprises the following steps:

[0040] (1) Recycle waste lead-acid batteries for pretreatment; recycle the waste acid in the lead-acid batteries into the waste acid tank, and recycle the clapboard;

[0041] (2) Use the crushing and sorting system to process the waste lead-acid batteries after step (1) pretreatment: the waste lead-acid battery materials after step (1) pretreatment enter the crusher through the feeding port on the upper part of the crusher After the crushing is completed, the material is discharged, and then enters the hydraulic grading box. According to the density of the material, it is gradually classified through multi-stage conversion under the action of water to obtain lead paste, grid and plastic respectively;

[0042] (3) transporting the grid separated from the step (2) to the drying furnace of the drying system through the grid conveying pipe...

Abstract

The invention discloses a processing system and processing technology of a waste lead-acid storage battery and application of regenerated lead. The processing technology comprises the steps of performing processing by a smashing and separation system to obtain lead paste, a grid and plastic after a recycled lead-acid storage battery is processed in advance, and drying the grid by a drying system and then transmitting the grid to a lead stove; and processing the lead paste sequentially by a melting system, a lead dross removal system and a dust collection system, transmitting the lead paste tothe lead stove after processing to mix with the grid in the lead stove for smelting, and obtaining the regenerated lead after processing. The technology employing the system to process is simple to operate and is high in recycling rate, the addition of other metal elements can be controlled by the processing process, so that the regenerated lead can be used for preparing power battery lead powderand also can be used for preparing the grid of the lead-acid storage battery, the influence of the waste lead-acid storage battery on an environment is achieved, the lead resource development is alsogreatly saved, and the processing technology has good social and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of electrochemistry, and in particular relates to a waste lead-acid storage battery treatment system, a treatment process using the system, and the application of recovered regenerated lead. technical background [0002] As the most widely used chemical power source in the world, lead-acid battery has the advantages of stable voltage, safety and reliability, low price, wide application range and abundant raw materials. According to incomplete statistics, my country's lead-acid battery manufacturers have reached about 1,500, and the production volume has increased substantially at a rate of about 20% per year. In recent years, due to the development of the automobile industry, the proportion of lead used in lead-acid batteries to lead consumption is also increasing, from 27% in the 1960s to 80-85% at present; With the rapid development of China and the promotion of clean production and environmental protecti...
