Problems solved by technology
However, in my country, a large number of domestic secondary lead enterprises are small in scale, low in investment, backward in technology, outdated in equipment, low in recovery rate, low in comprehensive utilization rate, high in energy consumption, and seriously polluted. technology, all of which use primitive and backward earthen stoves or small reverberatory furnaces to melt lead grids and lead paste, and discharge lead dust, lead vapor, and sulfur dioxide in an open manner, which not only seriously pollutes the ecological environment, but also produces tens of thousands of tons of lead dust every year. Scattered into the natural environment with sulfur resources, causing damage to the soil environment

Description
technical field [0001] The invention belongs to the field of reuse of waste lead-acid batteries, and in particular relates to a comprehensive reprocessing device for waste lead-acid batteries with reasonable design, energy saving, emission reduction, high efficiency and environmental protection. Background technique [0002] At present, for the comprehensive treatment process of waste lead-acid batteries, developed countries have mature processes. Developed countries have gone through three stages of fire method, semi-wet and semi-fire method and full wet method, and the recovery rate of lead has also increased from 85% to 95%. %, the most advanced full-wet process not only ensures a high recovery rate of lead, but also realizes clean production in the whole process, eliminating all potential pollution hazards in the production process of secondary lead. However, in my country, a large number of domestic secondary lead enterprises are small in scale, low in investment, backw...
