Undoubtedly, this is the most suitable way to recycle the replaced waste lubricating oil. This can not only make full use of resources, but also avoid environmental pollution caused by random disposal. There are regular refineries recognized by the state all over the country, and the oil recovered and processed by these manufacturers can meet the national standards and can be purchased with confidence.
Second, the engine oil gradually deteriorates, producing organic acids, gums and asphaltenes.
The regeneration of waste engine oil is to remove impurities in engine oil by means of precipitation, distillation, acid washing, alkali washing and filtration. It is a toxic substance and a solid hazardous waste that is explicitly prohibited by the state. It is strictly forbidden to buy and sell waste engine oil at will, and it should be handled by qualified waste engine oil treatment enterprises.
The waste engine oil itself is not damaged much, but the additives in it have expired in cumulative use and contain impurities in the engine. After purification and adding new additives, it can be returned to the market as regenerated engine oil with the same performance. The United States is very developed in this respect.
Waste engine oil can also lubricate parts with low requirements for lubricating oil. For example, mechanical metal hinges such as the chain of our bicycles, the cab locks of excavators, loaders and other equipment can be coated with waste engine oil to achieve lubrication, friction reduction and rust prevention.
In the construction site, waste engine oil can be used in building formwork to prevent the formwork from sticking to cement, and it can also play a role in rust prevention and corrosion protection.
Although diesel oil extracted from waste engine oil may damage the fuel system of vehicles, it is not a big problem to use it in cooking stoves used by catering enterprises or some machinery factories. Moreover, the price of fuel extracted from waste engine oil is much cheaper than the gas on the market, and some catering enterprises and machinery factories are also willing to use this fuel.
Units engaged in waste engine oil recovery must be solid waste business units that have obtained hazardous waste business licenses. In Beijing, there are four enterprises that can recycle waste engine oil, namely Zhongshou Fine Filter, Tai Ding Peng Yu, Beijing Ecological Island and Jinyu Mangrove Forest.
In addition to recycling and reprocessing, the little waste engine oil replaced by our own excavator can also be used as too precise machine gears or sliding rails to moisten the construction site, and the waste engine oil can also be used in building formwork to prevent the formwork from sticking to cement, thus achieving the effect of rust prevention and corrosion prevention.
