Abstract

The invention discloses a waste mineral oil purification device and a purification method thereof, and is characterized in that the waste mineral oil purification device comprises an instant heating unit, a hardening and tempering unit, a separation unit and a security unit, and adopts a two-layer process frame platform to form the complete waste mineral oil purification device, an intelligent control system consisting of a PLC or DCS, a display control instrument and a valve is used for realizing automatic control; the invention further discloses a waste mineral oil purification method. According to the waste mineral oil purification device, the waste mineral oil purification treatment capacity can be 3-20 t / h, the waste mineral oil purification device is suitable for purification treatment of various kinds of waste mineral oil, the water content of the treated waste mineral oil is smaller than 0.3% (wt%), and the impurity content is smaller than 0.3% (wt%); regenerated base oil is obtained by a series membrane filter unit, so that regeneration of the waste mineral oil is realized. Compared with the prior art, the invention solves the problems of long treatment time consumption, complex process, cumbersome control, low treatment efficiency, poor treatment effect, unstable process, low oil product adaptability and the like of the existing waste mineral oil purification device, and obviously improves the economic benefit.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of waste mineral oil resources, in particular to a waste mineral oil purification device and a purification method thereof. Background technique [0002] Waste mineral oil has been included in the "National List of Hazardous Wastes", numbered HW08, its main components are hydrocarbons with a relatively small number of carbon atoms, most of which are unsaturated hydrocarbons, and have stable performance. Waste mineral oil mainly comes from petroleum exploration, natural gas exploitation, refined petroleum product manufacturing and other related industries, including various waste lubricating oil, waste internal combustion engine oil, waste gear oil, waste hydraulic oil, etc. [0003] Waste mineral oil is a complex mixture of various substances, the main components of which are C15-C36 alkanes, polycyclic aromatic hydrocarbons (PAHs), olefins, benzene series, phenols, heavy metal i...
