THERMAL DESORPTION TREATMENT SYSTEM FOR WASTE BATTERIES

This application provides a waste battery thermal desorption treatment system. The waste battery thermal desorption treatment system includes: a rotary kiln, provided with a feed port, a thermal desorption cavity, a heating cavity, a discharge port, and a first exhaust port, where at least part of the thermal desorption cavity is located in the heating cavity and is rotatably provided relative to the heating cavity; a dust removal apparatus, including a housing and a dust removal structure disposed in the housing, where the housing is provided with a gas inlet port and a second exhaust port in communication with the first exhaust port, and the dust removal structure is configured to collect impurities in a gas exhausted from the first exhaust port, to enable gaseous components separated from the impurities in the gas to enter the second exhaust port; a condenser, in communication with the second exhaust port, to condense an electrolyte constituent in the gaseous components and form an electrolyte; and an adsorption column, where a defluorination agent is disposed in the adsorption column, to use the defluorination agent to perform dry defluorination on remaining constituents in the gaseous components. This application resolves the problem of low recycling efficiency of waste lithium batteries in the prior art.
