The invention provides a continuous
carbonization and
pyrolysis treatment method of a waste
lithium battery. The method adopts the following treatment flow of step 1, preheating, specifically, preheating a
carbonization device to a
working temperature; step 2, pretreating, specifically, discharging and crushing the
lithium battery, wherein firstly, the
lithium battery is put into a
temporary storage tank after being subjected to full
discharge and enters a
crusher through a closed conveying device, and after crushing,
mixed materials enter the
carbonization device; step 3, performing a carbonization and
pyrolysis treatment process and a gas
combustion process; step 5, performing a
tail gas treatment process; and step 6, sorting
solid materials discharged from the carbonization device. According to the treatment method of the waste
lithium battery, isolation between a carbonization chamber and gas
combustion in the carbonization process is realized, the
mixed materials obtained after the waste
lithium battery is crushed are heated through the indirect
heat transfer mode between gas
combustion as well as an
auxiliary heating device and the carbonization chamber,
oxygen is completelyisolated in the carbonization chamber, and oxidation of
metal in the carbonization chamber is effectively avoided through the control by means of the
pressure difference and a one-way valve, so that the utilization value of the final product is improved.
