Problems solved by technology

[0004] The living standard of the existing people has improved, and the edible consumption of oil has also increased in a large amount, and the oil content in the kitchen waste material is relatively high; the kitchen waste oil is easily used by criminals to recycle and sell as edible oil; existing better One way is to recycle and smelt biodiesel, but the cost is relatively high. At present, it is mostly wasted in the kitchen or treated as feed
[0005] For industrial motor oil, the existing method of recycling after being discarded is cumbersome, and most of them are discarded, which not only causes a waste of resources but also causes environmental pollution
[0006] In the existing oil refining method, the smelted products have a relatively large odor, and it is difficult to use waste oil, waste engine oil, and plastics with different components for mixed oil refining, and it is difficult to achieve in a single refining process. Deodorization treatment of re-refined oil, and it is difficult to re-refined to reach the standard oil grade

Embodiment 1

[0032] Embodiment 1: 200ml of waste oil (edible kitchen waste oil) is used as raw material.

[0033] Step 1: mixing materials, sealing the inside of the waste oil distillation tank;

[0034] Step 2: heating, continuous heating after mixing, the heating temperature is between 300°C and 400°C;

[0035] Step 3: Condensation. After the mixture is liquefied and tumbling, the heated steam enters the condensation pipe, the condensed liquid is collected, and left to cool to form condensed oil; the cooling liquid presents a lighter transparent brown color.

[0036] The formula of pickling neutralizer corresponding to every 200ml of condensed oil is as follows: glacial acetic acid (liquid) 4ml, phosphoric acid (liquid) 6ml, oxalic acid (granule) 4g, absolute ethanol (liquid) 4ml, after stirring and mixing the above, Add concentrated sulfuric acid with a mass fraction of 92%-98% to 200ml, and then stir evenly.

[0037] Then take out 5% of the configured pickling neutralizer (that is, 1...

Embodiment 2

[0043] Embodiment 2: 200ml of waste engine oil (industrial equipment waste oil) is used as a raw material.

[0044] Step 1: Mix the materials, distill the inside of the waste engine oil tank, and seal it;

[0045] Step 2: heating, continuous heating after mixing, the heating temperature is between 360°C and 380°C;

[0046]Step 3: Condensation. After the mixture is liquefied and tumbling, the heated steam enters the condensation pipe, the condensed liquid is collected, and left to cool to form condensed oil; the cooling liquid is generally brown.

[0047] The formula of pickling neutralizer corresponding to every 200ml of condensed oil is as follows: glacial acetic acid (liquid) 8ml, phosphoric acid (liquid) 6ml, oxalic acid (granule) 6g, absolute ethanol (liquid) 6ml, after stirring and mixing the above, Add concentrated sulfuric acid with a mass fraction of 60%-75% to 200ml, and then stir evenly.

[0048] Then take out 8% of the configured pickling neutralizer (that is, 16m...

Embodiment 3

[0054] Embodiment 3: The raw material adopts waste plastics (solid 10kg).

[0055] Step 1: Mixing materials, putting waste plastic solids into the interior of the distillation tank, and sealing;

[0056] Step 2: heating, continuous heating after mixing, the heating temperature is between 380°C and 400°C;

[0057] Step 3: Condensation. After the mixture is liquefied and tumbling, the heated steam enters the condensation pipe, the condensed liquid is collected, and left to cool to form condensed oil;

[0058] Take out 200ml of coolant for later use; the coolant is dark brown in color.

[0059] The formula of pickling neutralizer corresponding to every 200ml of condensed oil is as follows: Glacial acetic acid (liquid) 10ml, phosphoric acid (liquid) 8ml, oxalic acid (granule) 8g, absolute ethanol (liquid) 8ml, after stirring and mixing the above, Add concentrated sulfuric acid with a mass fraction of 60%-75% to 200ml, and then stir evenly.

[0060] Then take out 10% of the conf...

Abstract

The invention discloses a method for preparing recycle oil. The method comprises the following steps: adding illegal cooking oil, used oil and plastics of any component into a distillation tank, wherein the components can be totally illegal cooking oil or totally used oil or totally plastics, and also can be any combination of the three; sequentially heating, condensing, pickling, performing primary filtering, performing alkaline wash, performing secondary filtering, and blending oil to obtain refined oil product reaching the ordinary level. The invention also discloses a formula for preparing a pickling neutralizer in the pickling process by utilizing glacial acetic acid, phosphoric acid, oxalic acid, absolute ethyl alcohol and concentrated sulfuric acid. The invention aims to provide a method for preparing recycle oil and a pickling neutralizer thereof in the preparation process, the illegal cooking oil, used oil and plastics of different components can be effectively mixed to obtain the recycle oil, the applicability is wide, and requirements on raw materials are low. Moreover, oil is scrubbed in the production process, and the finished oil meets the oil grade requirement and can be used for requirements of normal vehicle and industrial oil.

Description

technical field [0001] The invention belongs to the field of oil refining, in particular to a method for preparing re-refined oil and a pickling neutralizer in the preparation process. Background technique [0002] With the rapid development of society, the demand for various energy sources is increasing day by day, especially the demand for power energy such as oil is huge. With the vigorous exploitation of human beings, resources are increasingly scarce. At the same time, with the continuous pollution of the environment by human beings, environmental protection has become a common problem faced by all human beings. With the development of science and technology, smelting and recycling technologies such as kitchen waste oil (commonly known as gutter oil), waste engine oil, and waste plastics are becoming more and more mature, and energy saving and environmental protection are strongly advocated. [0003] With the rapid development of the plastics industry, the application ...
