The invention relates to the technical field of oil field environmental protection, in particular to a microwave deoiling recovery device for oil-containing articles and an application method thereof.By effectively setting a microwave processor, a vacuum pump, a sprayer, a dust collector, a dry ash collection box, a condenser, an oil-water stratifier, a thermal oxidizer and other components, thedeoiling process of the oil-containing articles has real-time visualization, controllable operation, clean deoiling and reliable performance. The microwave deoiling recovery device for oil-containingarticles and the application method thereof can achieve a more convenient, low-cost, and high-efficiency deoiling treatment effect without external nitrogen blowing by adopting a mode of microwave heating, for-vacuum and water-spraying circulation, so that the material cost is reduced; and the related operations can achieve automatic control, so that the manpower cost is reduced, the operation efficiency is improved, and the application range is wide.
