Problems solved by technology

The fatal disadvantage of these processes is that secondary pollution will occur after the waste oil is regenerated, and acid slag, waste clay and waste water that seriously pollute the environment will be formed, which are difficult to treat
As a result, the competitiveness of the process is also reduced

Embodiment 1

[0049] A method for recycling waste automobile oil, comprising the following steps:

[0050] (1) Collect waste engine oil in scrapped cars, including various oils and waste liquids, such as residual fuel in the fuel tank, engine oil in the engine case, transmission oil, coolant, brake fluid and lubricating oil, etc. These waste liquids Separately recover through different pipelines to be processed;

[0051] (2) Preparation of activated clay: Mix distilled water and bentonite (150 mesh) at a ratio of 1L:1.5kg, then add hydrochloric acid accounting for 15% of the mass of bentonite, stir evenly, and then react at 100°C and 2MPa for 2.5h; then add Distilled water (the volume added to the reactant accounts for half of the volume of the reaction vessel) and silver nitrate, react for 15 minutes to form a white precipitate; let it stand for 50 minutes, pour off the supernatant, drain the precipitate, dry, and pulverize to obtain activated clay;

[0052] The amount of silver nitrate u...

Embodiment 2

[0062] A kind of device that is used to realize the method described in embodiment 1 will recycle the waste automobile oil product, its structure is as follows figure 1 As shown, it mainly includes pickling settling tank 3, distillation still 8 and plate and frame filter press 13, and the three are connected successively;

[0063] The adopted pickling settling tank 3 is a cylindrical tank with a conical bottom. The outer circumference of the cylindrical tank is the insulation layer 2, which is a solid structure made of PVC (polyvinyl chloride) or RPP (reinforced polypropylene), the insulation layer 2 can avoid the temperature difference between the external environment and the oil The circulation of the settling oil can achieve a better settling effect; the conical bottom of the pickling settling tank 3 is provided with a drain valve, which is not only the inlet of waste engine oil, but also used to discharge mechanical impurities after pickling and settling; The middle and l...

Abstract

The invention discloses a method and a device for recycling oil products of a scrapped car. The method comprises the following steps of: collecting waste engine oil in the scrapped car, preparing activated clay, pretreating waste engine oil, pickling and settling the waste engine oil, blending and distilling the waste engine oil and the activated clay, filtering the distilled waste engine oil and the like. The device comprises a pickling and settling tank, a distilling kettle and a plate-and-frame press filter which are connected sequentially. The method provided by the invention only needs continuous primary settlement-activated clay distilling, and then the recycled oil requirement is reached through filtering, and the operation working procedures are reduced greatly; and the distilling and clay blending are combined into a working procedure, the consumption of the activated clay can be reduced obviously, and the recycled oil yield is improved by 10-15%. The periphery of the settling tank is provided with a temperature preservation layer, the oil products in the whole settling period can be at the ideal state, the annular flow of the settled oil caused by the temperature difference between the external environment and the oil is prevented, and a better settling effect can be achieved.

Description

technical field [0001] The invention relates to a method and a device for recycling waste automobile oil products. Background technique [0002] The recycling of automobile waste engine oil is of great significance. The first is to save resources and turn waste into treasure, which is conducive to the full utilization of oil resources. According to statistics, the state of Alabama in the United States produces 17 million gallons of waste motor oil every year. If the waste motor oil is recycled, it can provide power for 5,000 cars. If 50% of the motor oil in our country is recovered, it is actually equivalent to building 12 oil refineries. From this point of view, the regeneration and utilization of automobile engine oil can produce huge economic benefits. Secondly, it is beneficial to prevent environmental pollution, avoid soil and water pollution and maintain ecological balance. [0003] The quality of the oil depends on the content of hydrocarbons, accounting for about...
