Description

Waste lubricating oil regeneration processing device

Technical Field

The invention relates to the technical field of lubricating oil recovery equipment, in particular to a waste lubricating oil regeneration processing device.

Background

Lubricating oil is a liquid lubricant used on various types of machinery to reduce friction and protect machinery and workpieces, mainly plays roles of lubrication, cooling, rust prevention, cleaning, sealing, buffering and the like, and mainly takes lubricating oil fraction and residual oil fraction from a crude oil distillation unit as raw materials. The most important properties of lubricating oils are viscosity, oxidation stability and lubricity, which are closely related to the composition of the lubricating oil fraction. Viscosity is an important quality indicator reflecting the fluidity of lubricating oils. Different conditions of use have different viscosity requirements. High viscosity lubricating oils are used for heavy duty and low speed machines. The oxidation stability indicates the oxidation resistance of the oil in the use environment due to the temperature, oxygen in the air and metal catalysis. After oxidation of the oil, depending on the conditions of use, fine, asphaltene-based carbon-like substances, viscous lacquer-like substances or films, or viscous water-containing substances are formed, which reduce or lose their properties of use. Lubricity means the friction-reducing property of the lubricating oil. Part of the components deteriorate due to oxidation, cracking, condensation and the like of the lubricating oil in the using process, and certain impurities (such as dust, light oil, abraded metal particles and the like) are mixed from the outside, and part of the additives are damaged. When the deteriorated components and impurities are accumulated to a certain degree, the lubricating oil can not be used any more, and becomes waste lubricating oil.

The regeneration process of the waste lubricating oil adopted by a plurality of waste oil regeneration manufacturers in China adopts an acid/soil regeneration method, and the waste lubricating oil is regenerated by a sulfuric acid pickling-clay refining method. The acid/soil method causes a large amount of acid sludge due to the washing with sulfuric acid, and causes environmental pollution. The waste lubricating oil is heated circularly by distillation, so that the heat carrier and the heat carrier circulating pump have the heat resistance for bearing the temperature of more than 450 ℃, the heating temperature is high, the evaporation area is small, the energy consumption is high, and the cracking is easy.

Still another regeneration technique for used lubricating oil is to use a vacuum oil filter to remove moisture, gas and mechanical impurities from the used lubricating oil. However, the vacuum oil filter is suitable for on-line purification of mechanical lubricating oil, but the medium and high-grade internal combustion engine oil, engine oil and some impurity oils with high viscosity and complex impurity-containing components cannot be filtered, so that filter blockage and incomplete impurity removal of the vacuum filter are often caused. The basic method in the regeneration process of the waste lubricating oil does not need to separate the methods of sedimentation, distillation, acid washing, filtration and the like, wherein the sedimentation is to settle the waste oil, so that impurities are reduced and separated. The settling time is determined by oil quality and oil temperature, the higher the oil temperature, the smaller the viscosity, the easier the impurity is to drop, the shorter the settling time, but the traditional settling equipment can not ensure the constant temperature heating and the sufficient heating of the waste lubricating oil, resulting in overlong settling time, and because the lubricating oil has high boiling point and high temperature, the characteristic of cracking is generated, so the time of the waste lubricating oil staying in a high temperature area is reduced, and the equipment capable of fully performing distillation work is necessary.

The following problems exist in the prior art:

1. the settling time is determined by oil quality and oil temperature, the higher the oil temperature is, the smaller the viscosity is, the easier the impurities are to fall, the shorter the settling time is, and the waste lubrication heating cannot be carried out in the traditional settling equipment, so that the settling time is too long;

2. the traditional equipment does not have equipment which can reduce the retention time of the waste lubricating oil in a high-temperature area and can fully carry out distillation;

3. the method for solving the problem of blockage of the filtering equipment by the traditional equipment is to stop the whole regeneration process of the waste lubricating oil and then treat the filtering equipment, so that the regeneration time of the waste lubricating oil is prolonged, and the output and the yield of finished products are greatly delayed;
