Description

Technical Field

[0002] Waste oil refers to waste oil generated in food processing, catering services, and industrial production, including kitchen waste oil, waste cooking oil, and industrial waste oil. Due to their complex composition and potential environmental hazards, direct disposal or improper treatment of these oils can pollute the ecological environment. Through appropriate refining and conversion, waste oil can be used as a raw material for biodiesel production. Biodiesel is a renewable and clean energy source based on oils, produced through transesterification. It has advantages such as low carbon emissions, environmental friendliness, and good biodegradability, and can partially replace petrochemical diesel in transportation, industrial fuel, and other fields. The efficient utilization of waste oil can not only reduce environmental pollution but also provide a sustainable solution to the energy shortage problem. The recycling and reuse of waste oil is gradually becoming an important research direction. However, due to the complex composition of waste oil raw materials, which often contain a large amount of impurities, moisture, and other unstable components, existing technologies show significant shortcomings in impurity removal and quality improvement. Furthermore, traditional homogenization and stratification equipment lacks the ability to dynamically adjust to the characteristics of the raw materials, making it difficult to adapt to the variable properties of waste oil, resulting in low product purity and refining efficiency.
