Problems solved by technology

[0003] And major oil fields, oil refineries, and other oil factories and mines, etc., when repairing and repairing pumping units, oil pipelines, cleaning and other operations, transport bags of scattered oil, bulk orders, etc., as well as waste bags for transporting oil sludge, slurry, and dirty oil. etc. After use, the discarded oil bags and waste slips have been filled with oil, so they are impregnated with a lot of oil, and there is still a certain amount of water and soil. They are black and dirty and cannot be disposed of, so they cannot be treated like ordinary plastic products. Recycled and used as oil refining, one is that the oil is too miscellaneous and there are too many impurities to be classified, and the other is that the waste bags and loose sheets are mainly polymerized such as polyethylene, polypropylene, polystyrene, etc. However, this component is easy to coke after being heated and sticks to the wall of the ax, causing the reaction ax to be unable to use normally, so the refineries cannot recycle, resulting in a large amount of waste

Embodiment 1

[0018] A method for extracting fuel oil by utilizing waste oil bags, waste slips and waste plastics, the method is:

[0019] 1) Add waste oil bags, waste sheets and other raw materials into the 20 cubic meter reaction ax; add the depolymerization agent and cracking agent into the reaction ax along with the raw materials, and the addition amount is 4% of the raw material mass; add the catalyst into the reaction catalyst tower inside the catalytic unit;

[0020] 2) Heating: control the heating rate to 150 degrees per hour, and heat for 2 hours;

[0021] 3) Continue heating, control the temperature at 250, the water vapor starts to flow out through the condenser, and enters the oil-water separator; the reaction cracking gas is catalytically modified by a catalyst, and then passes through the condenser to obtain liquid oil and gas products, and the liquid oil is fractionated to obtain gasoline , diesel oil; the gas products are collected and stored for reuse; until a little resid...

Embodiment 2

[0028] The difference between this embodiment and the above-mentioned embodiment is: the method 1) adding raw materials such as waste oil bags and waste sheets into 40 cubic meters of reaction ax; Add-on is 5% of raw material quality; Catalyst is added in the catalytic device of reaction catalytic tower; 2) Heating: control heating rate is 250 degree / hour, heating 1 hour; 3) continue heating, control temperature at 350 degree; Catalyst addition is Fill 100kg at a time.

Embodiment 3

[0030] This is the difference between the embodiment and implementation 1: the method 2) heating: control the heating rate to 200 degrees / hour, and heat for 1.2 hours; 3) continue heating, and control the temperature at 450 degrees.

[0031] In summary, the raw materials of the present invention are oil-soaked polyethylene, polypropylene, polystyrene, etc.; the depolymerization agent and cracking agent are added to the reaction ax along with the raw materials, and the raw materials can be directly added to the ax without pre-treatment. In this way, time and labor are saved; the depolymerization agent and cracking agent are added according to the ratio of 4% to 5% of the amount of raw materials added, and the catalyst is added in the catalytic device of the reaction catalyst tower according to the size of the reaction ax. Add once, and replace the catalyst multiple times. For example, in a 20 cubic meter reactor, add 50 kg of the catalyst and replace it every 6-8 ax produced; st...

Abstract

The invention discloses a method for extracting fuels by utilizing waste oil bags, waste throwaway and waste plastics, comprising the steps of: 1) adding raw materials like the waste oil bag and the waste throwaway into a reaction kettle; adding a depolymerizing agent and a decomposition agent along with the raw materials into the reaction kettle with the added amount thereof being 4%-5% of the mass of the raw materials; adding a catalyst into a catalytic device of a catalytic reaction tower; 2) heating for 1-2 hours and controlling the heating-up speed in the range from 150 to 250 DEG C / hour; 3) continuously heating and controlling the temperature in the range from 250 to 450 DEG C, causing water vapor to start flowing out via a condenser and enter an oil-water separator; catalyzing and modifying a reaction cracking gas via the catalyst to obtain liquid oil products and gaseous products via the condenser, and fractionating the liquid oil products to obtain gasoline and diesel; collecting, storing and recycling the gaseous products until a few residues are mainly residual oil and soil mixtures; 4) cleaning the reaction kettle, repeating the contents in the step 1); the method is simple in processes, environment-friendly and remarkable in economical benefits.

Description

technical field [0001] The invention relates to the technical field of energy production, in particular to a method for extracting fuel oil by using waste oil bags, waste slips and waste plastics. Background technique [0002] With the urgent shortage of social energy, various waste oil recycling technologies have emerged, such as the recycling of waste engine oil, and the recycling of waste plastic products, but they are all based on the relatively clean and mixed components of recycled materials Easy to determine, easy to determine the recycling process, easy to complete. [0003] And major oil fields, oil refineries, and other oil factories and mines, etc., when repairing and repairing pumping units, oil pipelines, cleaning and other operations, transport bags of scattered oil, bulk orders, etc., as well as waste bags for transporting oil sludge, slurry, and dirty oil. etc. After use, the discarded oil bags and waste slips have been filled with oil, so they are impregnat...
