METHOD AND DEVICE FOR TREATING WASTE OIL BY USING SULFUR-CONTAINING WASTE WATER
Document Type and Number:
WIPO Patent Application WO/2020/238164
Kind Code:
A1
Abstract:
A method and device for treating waste oil by using sulfur-containing waste water, belonging to the technical field of waste oil treatment. The waste oil is injected and mixed with sulfur-containing waste water in a certain proportion for demulsification, and then settled in a settling tank (10) to achieve three-phase separation of oil-water-residue. After treatment, the water content of the waste oil is < 5%, and the mechanical impurity content of the waste oil is < 2%. The method and device for treating waste oil by using sulfur-containing waste water significantly reduce the cost of treating waste oil, and also significantly reduce the difficulty of subsequent waste water treatment, save production costs, and improve the treatment effect of waste oil demulsification.
