[0026] specific implementation plan
[0027] The specific structure and process of the device are as follows:
[0028] The external waste oil is pumped into the vacuum dehydration tank 5 through the oil inlet pipe 31 by the oil inlet pump 1, and the connected liquid level gauge 8 is observed to control the oil level to a suitable position. Preheating and dehydration in the vacuum dehydration tank 5 through the electromagnetic heater 6 keeps the ultimate vacuum in the vacuum dehydration tank and reduces the boiling point of water evaporation; figure 1 The medium vacuum dehydration tank 5 contains a vacuum pump 2, a thermocouple 3, a vacuum gauge 4, an electromagnetic heater 6, and a connected liquid level gauge 8; wherein the vacuum pump 2 extracts the water vapor generated after the waste oil in the vacuum dehydration tank 5 is heated, and Send into gas purification device 22 through pipeline 36; Wherein thermocouple 3 controls electromagnetic heater 6 to regulate the tempera...

Description
technical field [0001] The invention belongs to the field of rectification and regeneration of waste oil, and relates to a complete set of device for waste oil catalytic cracking regeneration rectification without acid and alkali treatment under extreme negative pressure. Background technique [0002] Waste oil refers to various lubricating oils that can no longer be used after being used for a period of time due to the immersion of pollutants and oxidative deterioration of some components. The replaced lubricating oils are collectively referred to as waste oil. Lubricating oil is widely used in automobiles, ships, various industrial equipment and transmission parts of various machinery, etc., and the scope of use is very wide. According to incomplete statistics, China's waste oil can reach more than 20 million tons per year, which is a huge amount. If the replaced waste oil cannot be treated scientifically, it will waste a lot of resources and cause serious environmental p...
