Abstract

This disclosure provides a waste battery thermal desorption treatment system. The waste battery thermal desorption treatment system includes: a rotary kiln, having a feed port, thermal desorption cavity, heating cavity, discharge port, and first exhaust port; a dust removal apparatus, including a housing with a gas inlet port and a second exhaust port, and a dust removal structure disposed in the housing configured to collect impurities in a gas exhausted from the first exhaust port; a condenser, in communication with the second exhaust port, to condense an electrolyte constituent; and an adsorption column having a defluorination agent for dry defluorination on remaining constituents in the gaseous exhaust. This disclosure resolves the problem of low recycling efficiency of waste lithium batteries in the prior art.
