High-efficiency lubricating oil production and purification equipment

Abstract

The invention provides high-efficiency lubricating oil production and purification equipment. The high-efficiency lubricating oil production and purification equipment comprises a stirrer, a distiller, a heating sheet, an outer heat preservation shell, a main controller, an oil suction pump, a purifier, a cooling box, a cooling liquid injection pipe, a cooling liquid discharge valve, a waste oil discharge valve, a flow guide pipe, a lubricating oil eduction pipe and a mechanical valve. According to the invention, a crude oil purification buffer hopper, an inlet pipe and oil outlet pipe, an adsorption sheet and movable bolts, a cleaning plate, an observation window and a crude oil primary filter screen are arranged, so preliminary impurity filtering of crude oil is facilitated, and distillation effect is ensured; the crude oil is introduced into the crude oil purification buffer hopper through the inlet pipe, impurities are filtered through a crude oil primary filter screen, the filtering condition is observed through the observation window, so that cleaning can be conducted conveniently; meanwhile, iron impurities in crude oil can be adsorbed in an auxiliary mode through the adsorption sheet, so that the purity of the crude oil can be guaranteed; impurities in the crude oil primary filter screen and the crude oil purification buffer hopper can be cleaned by loosening the movable bolts and taking down the cleaning plate, the operation is convenient, and the filtering effect is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil production equipment, in particular to high-efficiency lubricating oil production and purification equipment. Background technique [0002] Lubricant base oils are mainly divided into three categories: mineral base oils, synthetic base oils and biological base oils. Mineral base oils are widely used and used in a large amount (about 95%), but in some applications, products formulated with synthetic base oils and bio-oil base oils must be used, thus making these two base oils develop rapidly. Mineral base oils are refined from crude oil. The main production processes of lubricating oil base oil are: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplementary refining. China's current lubricating base oil standards mainly modify the classification method and add two types of special base oil standards for low pouring an...
