[0002] Mineral oil is the most widely used chemical substance in the world. However, if the waste oil produced after the use of mineral oil is not properly handled, many harmful substances such as polycyclic aromatic hydrocarbons and chlorinated polycyclic aromatic hydrocarbons such as polychlorinated biphenyls (PCB) will be produced, which have strong carcinogenic effects. Waste mineral oil also contains many heavy metal additives added to improve the performance of oil and organic matter containing chlorine, sulfur and phosphorus, which will cause serious pollution to water bodies and soil, endanger the growth of animals and plants and the living environment of human beings, and is listed as a high-risk waste for priority management by the state. However, the deteriorated part of waste lubricating oil is less than 10%, which can be used to produce fuel oil and lubricating oil base oil for industrial power. Therefore, the comprehensive utilization of waste mineral oil is of great significance to alleviate the shortage of resources in my country, solve the bottleneck problem of oil supply and demand, improve the utilization rate of existing resources, and protect the ecological environment.

[0003] The existing waste mineral oil decolorization device needs to add a certain proportion of kaolin to the waste mineral oil when in use, then heat and stir it, and then pass it into a kaolin filter for filtration after stirring. However, the existing decolorization device lacks a structure for filtering the waste mineral oil, so the impurities inside the mineral oil will greatly affect the full contact between the activated kaolin and the mineral oil, thereby reducing the decolorization effect.

[0004] Therefore, it is necessary to provide a new waste mineral oil decolorization device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a waste mineral oil decolorization device, which solves the problem that the existing decolorization device lacks a structure for filtering the waste mineral oil, resulting in poor decolorization effect of the waste mineral oil.
