Fire and explosion prevention should be paid attention to in the recovery and regeneration of waste engine oil. It is best not to stir the distiller with steam, because steam stirring distillation is easy to cause explosion. Distilled light oil should be properly kept to avoid fire. "Clay adsorption" should control the speed when heating oil, not too fast, and don't touch the fire.
Besides the distillation equipment, other equipment used for waste engine oil regeneration can be simplified and should be strictly controlled. The suction filtration equipment can be designed and manufactured by steel plate, and thick cotton canvas can be used as the filter cloth for suction filtration. Chemical raw materials such as concentrated sulfuric acid and activated clay are available in chemical raw materials companies in big cities, and can also be ordered directly from manufacturers.
The recovery of waste engine oil is to collect small parts into many parts. First, make a contract with all kinds of recycled oil sources, let them keep the original dumped waste oil, and then make regular door-to-door purchases. The recycling price generally ranges from a few cents to one yuan. According to the pricing of oil products, about 70% of the refined oil can be processed after the waste oil is recovered, with diesel accounting for about 15% and the rest being mechanical oil, which has a great profit margin.
