THERMAL TREATMENT SYSTEM FOR ECO-FRIENDLY RECYCLING OF WASTE BATTERIES

WIPO Patent Application WO/2023/163336

A1

The present invention relates to a thermal treatment system for eco-friendly recycling of waste batteries, and provides a thermal treatment system comprising: a thermal treatment unit (110) provided in the shape of a chamber in which a heating means (111) is loaded, so that crushed medium- and large-sized waste batteries that have been discharged and crushed are put therein and thermally treated; a first thermal treatment control unit (120), which is coupled to one side of the thermal treatment unit (110) so as to form a transfer air current through an inert carrier gas in the chamber during a thermal treatment process, so that ignition inside the chamber is suppressed and, simultaneously, a vaporized electrolyte and organic substances pyrolyzed in a binder are liquefied by means of heat exchange; a second thermal treatment control unit (130) coupled to one side of the first thermal treatment control unit (120) so as to cool, through water cooling or air cooling, the temperature rising during heat exchange; and an organic impurity recovery unit (150) coupled to one side of the first thermal treatment control unit (120) so as to recover and store liquefied organic impurities, and thus the present invention increases a precious metal recovery rate, and separately recovers organic impurities so as to perform an eco-friendly and efficient thermal treatment process.
