The heat source is provided by two groups of annular heating tubes (3 tubes in each group, single tube power is 1200w, total power is 7200w), and the boiling hot water is circulated. Six overflow tanks are set in the upper part of the cylinder. Crude oil and debris can be discharged into the waste oil pool through the overflow pipe. The boiling state lasts for 20 minutes to complete a cleaning; the heat source part of the heating distillation link is provided by two groups of annular heating tubes. The cylinders are arranged from bottom to top in the device. Nitrogen is injected into the cylinder, and then the heating and oxygen-free carbonization stage is entered. It takes 35 minutes for the nitrogen in the cylinder to heat from 50°C to 300°C. After 10 minutes, the temperature can be further raised from 300°C to 380°C for 40 minutes. The dry distillation is completed. A bracket is provided at the bottom of the device to facilitate the separation of impurities from the filter element.
