Technical Field

[0001] The utility model relates to the technical field of oil refining devices, in particular to an automatic controlled high-efficiency energy-saving heavy oil and tire oil refining device. Background Art

[0002] Tire oil refers to the pyrolysis carbon black oil produced by the production of industrial carbon black from waste tires. The proportion of impurities and water in heavy oil and tire oil is usually in the range of 3-5%, and the remaining 95-97% are usable components.

[0003] Heavy oil and tire oil that have not been recycled, whether they are spilled or buried, will eventually flow into rivers, lakes, seas or groundwater, eventually causing water pollution. If heavy oil and tire oil are directly burned as fuel, the waste gas and waste residue produced will also cause a great degree of pollution to the atmospheric environment. Therefore, the recycling of heavy oil and tire oil is imperative, but the current recycling rate of heavy oil and tire oil is generally low, and the recycling cost of heavy oil and tire oil is too high, which makes it impossible to achieve large-scale promotion of heavy oil and tire oil recycling.
