The invention discloses a tree leaf treatment device. The tree leaf treatment device comprises an incinerator, a feeding device, a 
flue gas purifying device and a preheating device, wherein the feeding device is used for feeding materials to the incinerator; the 
flue gas purifying device is used for purifying hot 
flue gas discharged from the incinerator; the incinerator comprises an incinerator body, an incinerator head and an incinerator 
tail; a transmission spindle which is driven by a main motor is arranged in an 
incineration cavity in the incinerator; a plurality of 
material scattering bodies which are used for shifting materials are arranged on the transmission spindle; the feeding device comprises a feeding 
barrel which extends into the 
incineration cavity from a feeding opening; a feeding 
auger is arranged in the feeding 
barrel; the preheating device comprises a preheating hopper and a spiral flue which surrounds the preheating hopper; the 
flue gas purifying device comprises a 
flue gas discharging external channel and a pond; and a plurality of 
shower heads are arranged on the upper portion of the inside of the 
flue gas discharging external channel. By the tree leaf treatment device, dead animals can be effectively incinerated in a centralized manner, an 
incineration process is stable and efficient, sufficient incineration can be guaranteed, generated flue gas can be treated effectively, and 
smoke pollution can be avoided.
