Dry cleaning technology and dry cleaning processing system of waste lead-acid storage battery plastic

Abstract

The invention discloses a dry cleaning technology and a dry cleaning processing system of waste lead-acid storage battery plastic. The dry cleaning technology comprises the following steps: weighing broken plastic blocks and partition boards, pouring the broken plastic blocks and partition boards into a reaction container without a cover, adding cast iron and water, carrying out physical collision, carrying out stirring rotation in the container, heating to carry out a chemical reaction, after the water is distilled completely, and after opening an emptying valve, inflowing the materials including the plastic blocks, the partition boards, the cast iron, aluminum and impurities in the container into a vibrating screen, wherein an adsorption machine for adsorbing bubbles is arranged on a conveyor belt, a rapid sulfuric acid testing device is arranged on the conveyor belt, and sulfuric acid is returned into the reaction container to carry out the reaction again when the tested sulfuric acid concentration is higher than a concentration set value; the system is further provided with a compression molding and injection molding device, the compression molding and injection molding device is used for fusing the partition boards, or mineral waste residue and impurities are added for fusion pressure casting under the condition that the partition boards are fused. Secondary waste water cannot be generated, the problems that the partition boards cannot be recycled, a great deal of incineration cost is needed and the environment is polluted can be solved, the waste materials are changed into things of value, the method is simple and high in recycling utilization rate, and the technology has great economic values and market values.

Description

technical field [0001] The invention relates to the technical field of processing and recycling waste lead-acid batteries, in particular to a plastic dry cleaning process for waste lead-acid batteries and a dry cleaning treatment system thereof. Background technique [0002] Waste lead-acid batteries are recyclable wastes. Waste lead-acid batteries belong to dangerous goods determined by the state, and there are strict regulations on their recycling. According to relevant regulations, waste lead-acid batteries are not allowed to be smelted as a whole, they must be dismantled and sorted, and the separators, plastics, lead paste, lead grids, and electrolytes selected from the dismantling and sorting are subjected to environmental protection treatment, and then classified into Turn waste into treasure. Use the existing lead recovery technology for waste lead plaster and lead grid. For the existing partition and plastic treatment method, rely on a large amount of water washing,...
