Embodiment 1

[0048] The raw material distillation data is:

[0049]

[0050]

[0051] The system used in this embodiment to increase the treatment capacity of waste engine oil includes a raw material buffer tank 1, a raw material pump 2, a first heater 3, an atmospheric distillation tower 4, an atmospheric tower bottom pump 6, The second heater 8, the first vacuum distillation tower 9, the first vacuum tower bottom pump 12, the third heater 13, the scraper evaporator 15, the second vacuum distillation tower 16; the atmospheric distillation tower 4 The top of the tower is connected with the first condensing tower 19, the first reflux tank 7, and the light oil transfer pump 5 in sequence. The light oil transfer pump 5 extracts the light oil in the reflux tank 7, and a part of the light oil returns to normal pressure. In the distillation tower 4, another part of the light oil is transported to the storage tank for storage; the first reflux tank 7 is provided with a water recovery pipeli...

Embodiment 2

[0069] The raw material distillation data is:

[0070]

[0071] The step of waste engine oil regeneration is the same as embodiment 1, and the difference is the process parameters in each process, and concrete process parameters are as shown in table 4:

Abstract

The invention relates to the technical field of regeneration of waste machine oil and particularly discloses a method for increasing the regeneration treatment quantity of waste machine oil. The method for increasing the regeneration treatment quantity of the waste machine oil comprises the following steps: taking molten salt or heat-conducting oil as a heat carrier, performing flash evaporation and low-temperature reduced-pressure distillation, and performing waste machine oil regeneration under the condition of reduced pressure by using using a film evaporator. According to the process provided by the invention, the regeneration treatment quantity of the waste machine oil is increased to 60,000 ton / year; the method is simple to operate and low in equipment investment; various indexes ofregenerated finished product oil reach the use standard; furthermore, acid residue, waste gas and the like cannot be generated in the regeneration process, secondary pollution to the environment is avoided and win-win of economic benefit and environment-protecting benefit is realized.

Description

technical field [0001] The invention relates to the technical field of waste engine oil regeneration, in particular to a method for increasing the regeneration treatment capacity of waste engine oil. Background technique [0002] Waste engine oil refers to the impurities such as water, dust, other miscellaneous oils and metal powder produced by the wear and tear of the engine oil during use, which will cause the color to turn black, the viscosity to increase, and organic acids, colloids and asphalt-like substances to be generated and discarded. Oil. Because waste engine oil contains organic compounds such as chlorine, sulfur, and phosphorus, random disposal will cause pollution to the human body, soil and water environment. Therefore, waste engine oil has been listed as a hazardous chemical and must be recycled and regenerated in an organized manner. At present, the waste engine oil produced by automobiles and ships in my country reaches 1500×10 4 tons, plus the waste engi...
