How to dispose of the waste engine oil？

After we collect the waste engine oil, the next step is recycling the oil. The best method is using the engine oil recycling machine to get clean base oil. Today we will introduce the engine oil disposal equipment, which is produced by YANGJIANG Machine Manufacture Co., Ltd, one of the most famous engine oil recycling plant manufacturers. The engine oil treatment plant could recycle the waste engine oil, waste motor oil and waste lubricating oil. The product series of the engine oil recycling machine adopts the highest-quality material to manufacture it. The price of the plant is low and many users are satisfied with our engine oil recycling equipmentafter using our products. The engine oil treatment equipment is worthy of the users' trust.

You may ask how the engine oil recycling machine work. Let me list the practical steps of the equipment for you.

1. Water removal. After the waste oil is collected to the oil sump for water removal, it is placed in the oil refining pot. Then the waste oil is heated to 70-80 ℃ and stopped heating. Let it stand for about 24 hours, drain the surface water, and then slowly heated to 120 ℃ (when the oil temperature is close to 100 ℃, it should be slowly heated to prevent the oil from boiling and overflowing), so as to evaporate the water. After about two hours, the oil does not turn and black oil gas emerges from the oil surface. Yes.

2. Acid pickling. When the oil is cooled to average temperature, slowly add sulfuric acid under stirring (the concentration is about 92-98%). The acid consumption is generally 5-7% of the oil consumption (determined by the degree of oil contamination). After adding the acid, continue stirring for half an hour, and then stand for about 12 hours to drain the acid residue.

3. Alkali washing. Raise the temperature of the engine oil after pickling to 80 ℃, add soda ash (Na2CO3) under the agitation, mix it well, let it stand for 1 hour, and then use the test paper to check it as neutral, and then stand for more than 4 hours to drain the alkali slag.

4. Adsorption of activated clay. Raise the temperature of oil to 120-140 ℃, add activated clay under constant temperature and agitation (the dosage is about 3.5% of the oil quantity). After adding activated clay, continue to stir for half an hour, and stand at a constant temperature for one night under 110-120 ℃, and filter while hot the next day.

5. Filtration. The oil filter can be used for filtration, and qualified oil can be obtained after filtration. If there is no oil filter, the bag hanging method can also be used. The above is the general operation process of oil purification, but it should be determined according to the actual situation. If there is little impurity water, the first step can be omitted; if the color of oil is standard after acid and alkali treatment, it is unnecessary to use active clay to decolorize and absorb.
