Abstract
The invention relates to a method for regenerating waste lubricating oil. The method comprises the following steps of: precipitating and filtering waste lubricating oil and then carrying out molecule distillation; deodorizing in a waste lubricating oil regeneration and deodorization device; and then decoloring with white soil so as to obtain lubricant base oil. The method is simple to operate; and the lubricating oil subjected to the molecule distillation is deodorized twice in a primary deodorization tower and a film evaporator so that the obtained lubricant base oil has no odor, the color number of the lubricant base oil is less than 1.40 degrees, the kinematic viscosity of the lubricant base oil is 27-30m<2>/s, and the flash point of the lubricant base oil is large than 180 DEG C. Inspected by a product quality supervision and inspection department, the lubricant base oil is proved to be qualified.
