Problems solved by technology
Waste engine oil is not easy to burn fully, not only cannot effectively use its calorific value, but also easily generates a large amount of smoke and causes environmental pollution
At present, the pyrolysis process of waste engine oil is relatively rough, and the heating tube is used to heat it. However, due to the uneven transmission of the temperature of the heating tube in the oil, the engine oil close to the heating tube is easily overheated and coked and accumulated on the heating tube. The outer wall not only reduces the heat transfer efficiency of the heating tube again, but also requires regular coke cleaning operations, resulting in high cost and low yield of waste engine oil pyrolysis treatment

The invention belongs to the field of regeneration treatment of waste engine oil, in particular to a thermal cracking device for waste engine oil. The device includes a horizontal heating tank and a combustion tube running through the bottom of the horizontal heating tank. One end of the combustion tube is connected to the burner and is provided with an exhaust port, and the other end is provided with a sealing door; the end of the heating tank away from the burner is provided with an inlet. The oil pipe, the oil outlet pipe, and the combustion pipe are located in the heating tank, and the outer wall of the pipe is provided with a serpentine guide pipe. The invention has simple structure and ingenious design, can effectively promote the uniform heat dissipation of the combustion tube in the heating tank, and greatly reduce the occurrence probability of coking phenomenon on the outer wall of the combustion tube.
Description
technical field [0001] The invention belongs to the field of waste engine oil regeneration treatment, in particular to a waste engine oil pyrolysis device. Background technique [0002] With the advancement of my country's industrialization and modernization, the consumption of engine oil has also increased significantly, and the combustion consumption of engine oil is different from that of fuel, but it is mixed with a large amount of impurities, making it unusable. In the prior art, these waste engine oils are combusted or repyrolytically distilled to separate fractions such as gasoline. Waste engine oil is not easy to burn fully, not only cannot effectively use its calorific value, but also easily generates a large amount of smoke and causes environmental pollution. At present, the pyrolysis process of waste engine oil is relatively rough, and heating tubes are used to heat it. However, due to the uneven transmission of the temperature of the heating tube in the oil, the...
