Abstract

The invention discloses an efficient and energy-saving secondary lead smelting technology. The efficient and energy-saving secondary lead smelting technology comprises the steps of waste lead storagebattery collecting and crushing, material screening after waste lead storage battery crushing, material processing and classifying treating, secondary lead preparing and smoke treating and emitting inthe preparing process. According to the efficient and energy-saving secondary lead smelting technology, collected waste lead storage batteries are taken as raw materials for secondary lead, the condition that the waste lead storage batteries are littered at will to pollute the environment is avoided, the cost is reduced for the production process of the secondary lead, and lead ore resources areeffectively saved; secondary lead smelting is conducted by adopting a blast furnace, the blast furnace has the characteristics of being high in heat efficiency, high in specific productivity, high inmetal recycling rate, low in cost and small in occupation area, therefore, the secondary lead smelting efficiency is improved, and meanwhile energy consumption in the smelting process is reduced; andthe technology is simple, easy to operate and high in recycling rate, and therefore development of the secondary lead smelting technology is facilitated.

Description

technical field [0001] The invention relates to the technical field of secondary lead smelting, in particular to a high-efficiency and energy-saving secondary lead smelting process. Background technique [0002] With the development of the national economy, the use of lead is also increasing. Therefore, lead waste parts and waste materials are bound to increase day by day. The processing and production of recycled lead-lead-zinc ore is to use these lead waste parts and waste materials as raw materials to produce refined lead , lead-based alloys or lead compounds, according to the data published by the World Bureau of Metal Statistics, 51% of the world's total lead production is used to produce batteries, while 40% of the total lead production is obtained from the production of recycled lead, and waste batteries account for 90% of the raw materials for lead production. In addition to lead batteries, recycled lead raw materials include various waste lead plates, lead sheets, l...
