Industrial lubricating oil decolorization equipment is commonly used to treat various types of used or contaminated lubricating oils to restore their cleanliness and performance and extend their service life. These devices typically include the following key components and process steps:

Pretreatment stage:

1.Filtration: The lubricating oil is first passed through a pre-filtration system to remove large particles of impurities and solid particles. This prevents damage or premature clogging of the device in subsequent steps.

2.Heating: Lubricating oil usually needs to be heated to a certain temperature, so that it becomes more fluid, conducive to the subsequent treatment process.

Decolorization operation:

1.Adsorbent treatment: After the lubricating oil enters the decolorizing equipment, it is usually in contact with an adsorbent, such as refined clay, active clay, silica gel or other adsorbent. These adsorbents can effectively adsorb or convert impurities, pigments and harmful chemicals in lubricating oil.

2.Filtration: The treated oil is again passed through a filtration system to remove adsorbents and contaminants that have been adsorbed. This process can be repeated until the desired cleanliness and color is achieved.

Post-processing stage:

1.Dehydration: Some devices may also include a dehydration process to remove moisture from the oil and improve its insulation and heat resistance.

2.Additional processing: Depending on the specific application requirements, additional processing steps may be required, such as reprocessing or the addition of specific additives.

In general, industrial lubricating oil decolorization equipment can effectively remove impurities and polluting substances in lubricating oil through physical adsorption, chemical conversion and mechanical filtration and other ways, so that it can be restored to the state of reuse or reuse.
