(1) Collecting, recycling different types of lead-acid batteries from various places to the factory.
(2) Sorting, there are many different types of lead-acid batteries, when recycling lead-acid batteries need to sort out the different types of lead-acid batteries, mixing will cause great danger.
(3) Crushing, lead-acid batteries of the same type are sent by a conveyor belt to a crusher to get a mixture of crushed plastic pieces and liquid.
(4) Separation of plastics, the mixture enters the sorting machine in the rotating paddles to separate the plastics, dried and transported to the chemical plant to be made into plastic pellets to re-produce other plastic products.
(5) separation of lead, the remaining liquid mixture contains a large amount of lead, the use of screens to separate the foam and liquid, the foam through the deacidification process to remove impurities, precipitated flocculent is the lead, the wastewater purification and treatment of the direct discharge, the separation of the solid mixed with the foam, the use of dryers to remove water, in the smelting furnace heated straight to the lead as a liquid separated from the liquid poured into the caustic soda and the impurities reacted with the separation of the lead water.
(6) sulfuric acid treatment, sulfuric acid, a treatment is purified using the direct discharge method, followed by sulfuric acid sulfuric acid can also be processed into sodium sulfate, used in laundry detergent, glass, textiles manufacturing, while the sulfuric acid in liquid form can be separated and reused in the manufacture of lead-acid batteries.
(1) Environmental protection, lead and sulfuric acid are toxic substances, randomly discarded or directly to landfills will pollute the surrounding environment, causing harm to humans, animals and plants to survive.
(2) Saving resources, lead and plastic are recyclable resources, the recovery of end-of-life batteries can maximize the use of lead resources, reducing the cost of resource development and demand.
(3) Laws and regulations, many regions have developed relevant laws and regulations based on the recycling of batteries, and actively respond to the call to follow the national law.
The main hazard of lead-acid batteries is lead, which has no metabolic organs in the human body and can attack all organs. Lead poisoning in young children is common, and he directly affects the level of intellectual development of young children, and in serious cases, coma, convulsions, and even death may occur.
(1) pollution, in the battery preservation and treatment process to be very rigorous, lead-acid batteries in the material are harmful substances, the treatment of incomplete emissions make the factory around the serious pollution.
(2) Transportation, lead-acid batteries in a large number of collected after the unified transportation of the factory processing, the battery in the transportation process will also be dangerous.
(3) A wide range of battery types, different types of batteries need to be individually developed different recycling process, with the development of the battery, the battery recycling has challenges.
(4) Recycling in the informal sector, according to the World Children’s Fund, about half of the lead-acid batteries are recycled in informal factories, which have very poor processes, resulting in recycling hazards.
The recycling of lead-acid batteries should follow the standardization to ensure the recycling of batteries, which is very helpful to the environment and future development.
