There are still certain impurities and particles in the exhaust gas after secondary incineration, which will cause pollution when released to the outside. Therefore, dust is reduced through a cooling and dust reduction chamber. However, the filter at the gas release port is easy to be clogged and difficult to clean, which affects the use effect. In view of the above problems, it is necessary to provide a lithium battery positive and negative electrode material processing exhaust gas secondary incineration furnace that can scrape off impurities in the filter.
