Problems solved by technology

Compared with the inflow of waste oil, the amount of waste water in the ditch is large, and the waste oil enters the ditch and mixes with the waste water to form waste water containing a small amount of waste oil. If degradation drugs are used to degrade the waste oil in the waste water, the drug cost will be wasted , but also generate impurities such as oil sludge, which is not conducive to subsequent cleaning, and the maintenance cost is too high

Abstract

The invention relates to the technical field of waste oil recycling and in particular relates to an environment-friendly waste oil tower pipe type reverse-flow-process radiation heating and acid-freeoil extraction technology. According to the technology, electric radiation heating is adopted so that risks of fire heating are avoided, and solvent extraction is utilized so that acid and alkali hazard is solved; a reverse reaction technology is utilized so that the quality of a product is improved; an extracting agent is utilized so that the recycling rate is improved and a coking and blocking phenomenon is also extremely avoided; meanwhile, the production cost is also saved and the quality of recycled oil is improved; waste oil is mixed with an organic solvent so that the oil is dissolved in the organic solvent and impurities also can be washed in a sediment form; then the impurities can be completely separated from the oil through a filtering effect of a screen mesh so that the purityand yield of the recycled oil are improved; the extracting agent in an extracting system is used for continuously extracting filtrate and a micro-catalysis effect is realized, so that smooth proceeding of a subsequent procedure is facilitated; the waste oil is recycled so that resources are saved and pollution to the environment is also reduced, so that the technology accords with an environment-friendly development concept advocated in modern times.

Description

technical field [0001] The invention relates to the technical field of waste oil recovery, in particular to an environment-friendly waste oil tower tube type countercurrent method radiation heating acid-free oil extraction process. Background technique [0002] In the process of industrial production, petroleum or synthetic oil is used in many places. Some large enterprises consume hundreds of tons or even thousands of tons of petroleum or synthetic oil every year. In particular, in the steel rolling production line of metallurgical enterprises, the consumption Hydraulic oil and thin oil amounted to one million tons, of which dozens of tons were recovered as waste oil, and more than 90% of the remaining waste oil entered the rolling steel descaling water in the trench due to accidents such as leakage. Compared with the inflow of waste oil, the amount of waste water in the ditch is large, and the waste oil enters the ditch and mixes with the waste water to form waste water co...
