Introduction
Reasons for blackening of waste engine oil:
Cause 1 - high temperature and high pressure carbonization: the engine oil is easy to oxidize and deteriorate under harsh high temperature conditions, producing acid substances and synthesizing polymer deposits, so as to damage the lubrication. In addition, the combustion of exhaust gas into the crankcase will also promote oil oxidation deterioration. Therefore, after using for a certain period of time, the engine oil usually turns black and deteriorates, losing its proper lubricating effect. However, with the continuous improvement of the quality of lubricating oil, especially the popularization of thickened oil, the blackening of the oil does not necessarily mean that the oil is deteriorated. This is because the clean dispersant added to the thickened oil disperses the deposits on the parts in the oil, making the oil black. Whether it is deteriorated or not shall be tested for various indicators, and regular oil change shall be carried out according to quality to reduce unnecessary waste.
Cause 2 - insufficient fuel quality: the higher the olefin content in the fuel, the higher the sulfur content, the easier to form sludge in the gasoline engine, soot in the diesel engine, and the easier to blacken the engine oil.
Reason 3 - unreasonable equipment structure: different engine structure and working conditions, the sludge in the oil pan of the gasoline engine is mainly caused by the start and stop of the vehicle, the incomplete combustion due to the insufficient use of horsepower; soot is formed due to the incomplete combustion of the diesel engine, which causes the oil to turn black easily. The engine is overloaded for a long time, high-power and high-temperature operation makes the oil black. Change the engine oil without cleaning the engine or changing the engine oil filter element. After adding new engine oil, the new engine oil will be polluted due to the waste engine oil that has not been discharged completely. In addition, the cleaning function of new engine oil will clean the existing gum, carbon deposit and oil sludge in the engine and mix them into the engine oil to make it black.
Reason 4 - mixing of working condition and environment: the reason for the blackening of lubricating oil is mainly based on the production process and environment, such as the rubber tire industry. In the production process, rubber particles are used for pressing. During the pressing process, the rubber particles will be mixed into the lubricating oil to form black.
Summary: can the black oil be filtered and reused? The answer is yes. Large distiller, small centrifuge, medium decolorizing filter and small vacuum oil filter can be used to decolorize black oil. According to the specific situation of the specific treatment (Chongqing Zhongjing filtration equipment manufacturing Co., Ltd.) professional technical solutions to customers. Meet customer needs.
The equipment is suitable for the decolorization, deacidification, regeneration and purification of the seriously aged industrial lubricating oil and hydraulic oil. Restore the physical and chemical properties of the oil, make the purified oil reach the national standard of new oil quality, and reuse the standard. This product is widely used in petroleum, chemical, cement, metallurgy, mine, electric power, ship, machinery, military industry and other industries, such as engine oil, gear oil (open, closed), hydraulic oil, forming oil, gutter oil, track oil, compressor oil, vacuum pump oil, total loss system oil, axle oil, pneumatic tool oil, guide rail oil, bearing oil, cylinder oil, conduction oil, transformer Regeneration of industrial waste oil such as insulating oil (mineral oil, synthetic oil).
Characteristics of waste oil decolorization and regeneration purification equipment:
1. New technology separation function, our company's equipment can separate the non ideal components in the oil (such as low volatile, low ignition point substances, acids, alkali, water, kerosene, gasoline, diesel oil, methane, ethane, acetylene, naphthenic acid, polycyclic aromatic hydrocarbon and other polar substances) to achieve the separation effect, and then pump them into the conversion system for cooling through vacuum negative pressure, collect them to the collector for storage and discharge.
2. Recoverability index, which can recover viscosity, acid value reduction, condensation point, pour point, emulsification performance, viscosity temperature performance, corrosion performance, oxidation stability, etc., and improve oil flash point by 5% - 30%.
3. Ensure oil quality, unique heating device, oil surface and inner layer temperature balance, while the temperature of heating pipe wall of domestic and foreign traditional oil filter is above 300 ℃, oil aging instantly, while the inner layer and surface of our company's products are around 80 ℃, so as to ensure that oil quality will not be damaged.
