Problems solved by technology

The above equipment is easy to cause environmental pollution due to the addition of sulfuric acid, lye, etc., and the color of the prepared base oil will turn black and red, which will affect the quality of the base oil, and the added clay will absorb some base oil and make part of the base oil as The oil residue is discharged, which leads to a decrease in the recovery rate of base oil; w

Abstract

The invention discloses a black waste engine oil vacuum distillation system, which comprises a pretreatment kettle. The oil inlet of the pretreatment kettle communicates with a mixing tank through a pipeline, and an oil outlet of the pretreatment kettle communicates with a distillation still through a pipeline. The bottom of the distillation still is connected to a heating mechanism, and an oil outlet of the distillation still communicates with a cooling mechanism through a pipeline. An oil outlet of the cooling mechanism communicates with a gasoline-diesel transit mechanism and a base oil transit mechanism through pipelines, respectively and is connected to a gasoline-diesel finished product pot and a base oil finished product pot, respectively. The distillation still is internally provided with a thermometer, and the bottom of the distillation still is provided with a deslagging mechanism. The heating mechanism includes a cylindrical combustion chamber and a combustion machine which communicates with the cylindrical combustion chamber. An annular cold air cavity sleeves the cylindrical combustion chamber, communicates with one end of the cylindrical combustion chamber, and externally extends to form a mixing chamber. An air inlet of the annular cold air cavity is provided with a frequency-variable blower fan, and an air outlet of the mixing chamber communicates with the lower end of the distillation still.

Description

technical field [0001] The invention relates to a vacuum distillation system and process method of black waste engine oil, in particular to a system and process method for obtaining base oil through vacuum distillation of black waste engine oil. Background technique [0002] Lubricating oil has experienced a history of hundreds of years from its birth to the present, and has made great contributions to the development of human society, and its demand is also increasing. Due to the non-renewability of petroleum resources and the high production cost of lubricating oil, lubricating oil Oil recovery and reuse technology has attracted widespread attention. However, due to limited cognition of oil itself and limited production technology, the traditional process and equipment treatment effect is not ideal, and the production cost is high, the yield is low, and the oil quality is low. Poor and not environmentally friendly. [0003] At present, the equipment for obtaining base oil...
