The Investigation of the Recycling Technology for the Waste Acid Discharged from Waste Lead Acid Bat
| 英文摘要 | The tasks of the project were investigating the distribution of the waste acid from metal refineries and its recycling entities. The project completed collecting the information of waste acid recycling technology and its cost from many countries like America, Italy, England, Japan and China. And provided the suitable recycling method and technology for waste acid from waste lead batteries. For testing the concentrations of sulfuric acid, lead and iron for waste acid collected from domestic recycling entities, the result showed that the sulfuric acid concentration was 4.3~20.3%, lead concentration was1,670 μg/L～7,020 μg/L, iron concentration was 13,700 μg/L～402,000 μg/L. Field testing used the expanding transparency and the waste acids were from S55 and E52 entitues.It found that the method of expanding transparency could keep the collection rate of sulfuric acid above 80%, the removing rate of lead and iron also kept above 80%. The cost and profit of recycling waste acid for 6 recycling entities had been evaluated. The project also collected the green design data for lead batteries and evaluated its influence. The information of waste plastic recycling situations and applications of America, England, Japan and China were collected. The testing results of waste plastics collected from 6 waste lead battery recycling entities showed the lead concentration was 13.2～43.6 mg/kg, Cd and Cr were below 0.01mg/kg. The case strength of the lead acid battery and its mixing proportion. Currently, using 10% of the same level PP recyclable material is acceptable. The market information of recovery technology for lead acid batteries had been collected and analyzed for the influences to production and recycling industry. The project used the mass balance to predict the production of waste acid, and found the production rate was 12~17%. Besides, the stock-production rate had been evaluated by analyzing the consuming rate, the production rate and the wastes production rate. According the calculation of 6 domestic recycling entities, the consuming rate during refining process was 30%, the average of wastes production rate was 2.4% (included ashes and slags ). The evaluation of feedstock-production model for the refining process of waste lead acid batteries had been completed. It suggested that the production rate could be used as the evaluating factor for the feedstock- production of refining process. And the production rate could be calculated through the volume of products ( lead tablet + lead ingot + lead ice material ) divided by the feeding volume of waste lead acid batteries. | ||
