Method and system for recycling hazardous lead solid waste

Abstract

The invention belongs to a method and a system for recycling hazardous lead solid waste. The method comprises the steps that the hazardous lead solid waste generated in a plate separation and brushing process of storage battery manufacturing is collected; lead alloy components, applications and quantity of the hazardous lead solid waste are recorded definitely; the hazardous lead solid waste is separated, subjected to impurity removal and purified in a sealed environment to form waste lead powder; the obtained waste lead powder is labeled according to the lead alloy components, the applications and the quantity, classified and stored; the stored waste lead powder with the identical lead alloy components and the applications is taken, and mixed with lead powder ground by electrolyzing lead; a ratio of the weight of the added waste lead powder to that of the lead powder ground by electrolyzing lead is (10-20):100; and a mixture is placed in a mixer, stirred uniformly and recycled. The system comprises a lead powder conveyor, a lifting conveyor and an electromagnetic sieve separator. The method and the system can automatically separate and recycle the hazardous lead solid waste, and can effectively solve the problem that the hazardous lead solid waste pollutes an environment, and have the advantages of simple structure, low recycling cost, high resource recycling ratio, and good energy saving and environmental protection effects.

Description

technical field [0001] The invention belongs to a method and system for recycling and utilizing lead hazardous solid waste. Background technique [0002] The brushing process is the most polluting process in the battery manufacturing process. A large amount of lead-containing dust is likely to be generated during the production process, which not only pollutes the environment, but also affects the physical and mental health of employees. It must be treated in an environmentally friendly manner. [0003] The treatment of environmental protection is to adsorb the lead-containing dust produced by the pollution source, for example, to absorb the lead-containing dust released from the pollution source with a flat cloth bag, so that the lead-containing dust is adsorbed on the flat cloth bag to prevent it from scattering into the air to pollute the environment. However, after environmental protection treatment, a large amount of hazardous solid waste of lead will be produced, such ...
