| 摘要 |
The present invention relates to a system and a method for purifying waste oil, which improve oil production efficiency of diesel, lamp oil, and gasoline by preheating waste oil and pyrolysis oil in a preheater of pyrolysis oil, can gain diesel, lamp oil, and gasoline of high quality by primarily and secondarily separating diesel, lamp oil, and gasoline into water and oil, increase an output of oil by pyrolyzing the waste water in a vapor condition, remove condensable oil mist, tar, and other impurities in noncondensable gas discharged after purifying gasoline finally, and recirculate and pyrolyze the same again, thereby increasing oil production efficiency and maximizing treatment efficiency. |
