The second bevel gear 73 is coaxially sleeved and fixed on the outer wall of the oxygen supply pipe 61. The other end of the drive shaft 71 extends through the side wall of the furnace body 2 to the outside and connects to the drive mechanism 8. Waste liquid is supplied to the waste oil atomizing nozzle 4 through the oil supply pipe 41. After being atomized by the waste oil atomizing nozzle 4, it is sprayed downward from the top of the furnace body 2. The burner injects flames from the flame nozzle 21 into the furnace body 2 through the burner 3 to burn the atomized waste oil from the waste oil atomizing nozzle 4. During the combustion process, oxygen-enriched air is supplied to the area below the waste oil atomizing nozzle 4 through the oxygen supply pipe 61. The oxygen distributor 5 is driven by the drive mechanism 8 to rotate, so that the oxygen-enriched air is released evenly and prevented from gathering together. The oxygen distributor 5 evenly disperses the oxygen-enriched air, allowing it to fully contact and burn the waste oil. The combustion efficiency is high, the waste oil is burned completely, and the heat utilization rate of the burner is high.

[0033] In this embodiment, see Figure 2The drive mechanism 8 includes a motor mounting plate 81, a drive motor 82, a first sprocket 83, a second sprocket 84, and a transmission chain 85.
