Method for removing peculiar smell from regenerated base oil

The invention discloses a method for removing peculiar smell from regenerated base oil, which comprises the following steps: S1, introducing water into a removal box, and starting an ultrasonic generation controller to form an ultrasonic water bath; s2, the regenerated base oil is guided into a removal box, the regenerated base oil is put into an ultrasonic water bath, and peculiar smell is dissolved in water under the action of sound waves; s3, introducing nitrogen into the removal box, and carrying out gas stripping; s4, gas-phase diffusion of the smelly substances in the regenerated base oil and the water is realized through gas stripping, the smelly substances are discharged along with nitrogen, the discharged smelly substances are introduced into the adsorption tower together to adsorb the smelly substances, and the adsorbed nitrogen is introduced into the removal box again for recycling; s5, introducing the regenerated base oil and water from which the odor substances are removed into a centrifugal oil-
