Description

Technical Field

[0001] This utility model relates to the field of oil refining technology, and in particular to a high-efficiency and energy-saving thermal desorption oil refining device. Background Technology

[0002] Against the backdrop of continuously rising global energy demand and increasingly stringent environmental regulations, the efficient utilization and clean treatment of oil resources has become one of the core issues in the energy sector. With the continuous increase in oil extraction and the widespread application of oil products in various industrial production processes, the amount of impure oil products generated is also increasing. If these impure oil products are directly discharged, it will not only cause serious waste of resources but also pose a huge threat to the ecological environment.

[0003] Some existing thermal desorption oil refining units first send the inferior oil to be refined to a preheater via a feed pump for preheating, and then send it to the thermal desorption reactor. In the high-temperature environment of the reactor, which is isolated from air, the heavy components in the oil undergo thermal cracking and dehydrogenation reactions, transforming into light oil and gas components. Subsequently, these oil and gas components enter the separation stage consisting of a condenser and a gas-liquid separator. After condensation and cooling, liquid refined oil is obtained, realizing the purification and regeneration of the oil.

[0004] In existing technologies, after thermal desorption of oil, impurities of different types and densities gradually separate into layers, forming impurity oil layers of varying heights. Some devices struggle to adjust the extraction height in a timely manner based on the actual height changes of the impurity oil layers, affecting the purity and quality of the final oil. To address this issue, a high-efficiency and energy-saving thermal desorption oil refining device is proposed. Utility Model Content
