Technical Field

The invention relates to the technical field of industrial lubricating oil treatment, in particular to a comprehensive purification treatment system and a comprehensive purification treatment method for industrial lubricating oil.

Background

The industrial fluid represented by lubricating oil has the characteristic of low degradation degree, the stable performance of the lubricating oil guarantees the stable and efficient operation of industrial equipment, the lubricating oil liquid must keep certain cleanliness to meet the operation requirement of the equipment, and the mainstream solution at present is to replace the lubricating oil with reduced quality or carry out simple filtration treatment to prolong the service life in a limited way. The simple filtration has very limited purification effect on the lubricating oil, wherein the pollutants such as water and the like are difficult to separate by conventional means, and the significance for prolonging the service life of the lubricating oil is not great. The main components of the lubricating oil are petrochemical products or synthetic organic matters generally, the natural degradation difficulty is very high, the replaced lubricating oil becomes industrial hazardous waste, and relevant laws and regulations have strict regulations on the disposal mode of the lubricating oil, so that industrial users pay the purchase cost of the lubricating oil and the disposal cost of the waste simultaneously in the lubricating oil replacing process.

At present, the treatment of waste lubricating oil mainly has two technical directions:

the method has the advantages that waste lubricating oil is collected in a centralized manner, a mechanism with relevant quality is entrusted to recover and process the waste lubricating oil, the lubricating oil needs to be transported to a special processing factory by means of a professional transport tool and processed into a production raw material of the lubricating oil by means of a certain chemical process, the waste is treated, and the method does not contribute to prolonging the service life of the lubricating oil and reducing the cost of enterprises;

secondly, mechanical impurities, moisture and the like in the oil are removed through miniaturized processing equipment, and the oil is purified and then is continuously used; the Chinese utility model patent CN93239671.2 discloses a vacuum oil filter, which comprises an oil inlet valve, a coarse filtration tank, an oil heater, a vacuum tank, a condenser and a fine filter, and is characterized in that an omnibearing air extractor is arranged in the vacuum tank, and a series gear pump is arranged at the oil discharge position of the vacuum tank; chinese utility model patent CN201821302519.5 discloses an automatic fossil oil chemical industry oil-water separator and chinese utility model patent CN201720027350.6 also discloses an industrial lubricating oil on-line refining system.

However, because the working environment of the industrial lubricating oil is very complex, the component change of the industrial lubricating oil is large after the industrial lubricating oil is used, especially for some lubricating oil with higher viscosity grade, the whole recovery work of the lubricating oil can not be met generally through a single treatment means, and the recovery problem of the industrial lubricating oil can be solved only by carrying out grading treatment on different components of the lubricating oil and simultaneously carrying out circulating operation through matching of multiple treatment means.
