Lithium battery treatment system and treatment process

Abstract

The invention relates to the field of waste battery treatment, in particular to a lithium battery treatment system and a treatment process. The lithium battery treatment system comprises a shredder, acrusher, a magnetic separator, a pulverizer, an analyzer, a sorting device, a shunt valve, a collector I, a collector II, a collector III, a pulse dust collector I, a pulse dust collector II, a pulsedust collector II, a high-pressure fan I, a high-pressure fan II, a high-pressure fan III, an airflow sorter I, an airflow sorter II, an airflow sorter III, an induced draft fan I and an induced draft fan II, wherein the shredder is sequentially connected with the crusher, the magnetic separator, the pulverizer, the analyzer, the sorting device, the shunt valve, the collector I, the pulse dust collector I and the high-pressure fan II. The treatment system has a reasonable structural design, complete crushing of lithium batteries, high purity of recovered powdery substances, low pollution andhigh efficiency; the treatment process has simple and reasonable steps, low environmental pollution in a treatment process, high recovery rate and strong practicability.

Description

technical field [0001] The invention relates to the field of waste battery treatment, in particular to a lithium battery treatment system and treatment process. Background technique [0002] With the continuous advancement of science and technology, the development of electronic technology industry is getting stronger and stronger, and the replacement of electronic products is getting faster and faster. Mobile phone batteries are processed centrally. The early treatment of waste batteries is usually done by deep-sea burial. Although deep-sea burial has little impact on human life in a short period of time, the treatment of waste circuit boards in this way for a long time will cause serious environmental pollution. Serious, especially the pollution of seawater and soil, in addition to deep-sea burial, chemical treatment is often used, usually using strong acid or strong alkali to corrode the components in the mobile phone battery, and then the solution is processed to achieve...
