Description

Technical Field

[0001] This utility model relates to the field of waste pyrolysis technology, specifically to a rapid oil-gas separation device for waste plastic pyrolysis oil. Background Technology

[0002] Waste plastic pyrolysis oil is a reddish-brown, highly fluid fuel oil with low impurity content, produced by breaking down the high polymer macromolecules in waste plastics into low molecular weight hydrocarbons through processes such as thermal pyrolysis, catalytic pyrolysis, or hydrocracking in high-temperature and oxygen-free or low-oxygen environments. It can be used as fuel in cement plants, power plants, etc., and can also be processed into non-standard diesel oil or used as a chemical raw material to produce ethylene, propylene, etc., thus having both environmental and economic significance.

[0003] Currently, existing rapid oil-gas separation devices for waste plastic pyrolysis oil on the market mostly suffer from the following shortcomings during use: These devices often exhibit low oil-gas separation efficiency, resulting in the inability to quickly and thoroughly separate the oil and gas produced during pyrolysis, thus affecting the quality of the pyrolysis oil and production efficiency. Furthermore, the gases emitted by these devices contain harmful substances, which not only pollute the environment but may also adversely affect the health of operators. Therefore, we propose a rapid oil-gas separation device for waste plastic pyrolysis oil. Utility Model Content

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please refer to Figure 1-4 A rapid oil-gas separation device for waste plastic pyrolysis oil includes:

[0033] Container 1 has an air outlet pipe 3 at its top. One end of the air outlet pipe 3 passes through the container 1 and extends into the interior, where an oil filter screen 7 is fixedly installed. A spiral plate 6 is fixedly installed on the air outlet pipe 3 and inside the container 1. An air inlet pipe 2 is fixedly installed on the circumferential wall of the container 1. One end of the air inlet pipe 2 passes through the container 1 and is located on one side of the spiral plate 6. A valve 5 is fixedly installed on the circumferential wall of the container 1. One end of the valve 5 passes through the container 1 and is located near the bottom of the container 1.

[0034] The outer shell 4 is fitted onto the air outlet pipe 3 and is located directly above the container 1. A square frame 8 is provided inside the outer shell 4. Filter plate 13, filter plate 2 14 and filter plate 3 15 are arranged in the square frame 8 from top to bottom. The square frame 8 passes through the outer shell 4 and is fixedly installed with a sealing gasket 12. The sealing gasket 12 is located on one side of the square frame 8.

[0035] The drive component is located on one side of the housing 4 and is used to drive the box 8 to move left and right.

[0036] This invention provides a rapid oil-gas separation device for waste plastic pyrolysis oil, characterized by high oil-gas separation efficiency, stable pyrolysis oil quality, high production efficiency, and superior environmental performance. This device utilizes a combination of container 1, inlet pipe 2, outlet pipe 3, outer shell 4, valve 5, spiral plate 6, oil filter screen 7, square frame 8, sealing gasket 12, filter plate one 13, filter plate two 14, and filter plate three 15. By optimizing the internal structure, the device enables rapid and thorough separation of oil and gas, thereby improving the quality and production efficiency of the pyrolysis oil. Furthermore, the device prioritizes environmental performance, ensuring that the discharged gas does not contain harmful substances, effectively avoiding environmental pollution and health risks to operators.

[0037] In this embodiment, the driving component includes:

[0038] The fixing frame 11 is fixedly installed on one side of the square frame 8 and located inside the sealing gasket 12;

[0039] L-shaped plate 9 is fixedly installed on one side of the outer casing 4 and located directly below the sealing gasket 12. A threaded rod 10 is provided on one side of the L-shaped plate 9, and one end of the threaded rod 10 passes through one side of the L-shaped plate 9 and the fixing frame 11.

[0040] Rotating the threaded rod 10, through its threaded engagement with the L-shaped plate 9, causes the threaded rod 10 to move axially, driving the fixed frame 11 and the square frame 8 to move left and right. Since the square frame 8 is slidably connected to the outer shell 4, it can be easily pulled out of the outer shell 4, making it convenient for operators to clean or replace the filter plate 13, filter plate 24 and filter plate 35.

[0041] In this embodiment, the threaded rod 10 is threadedly connected to the L-shaped plate 9, and the threaded rod 10 is rotatably connected to the fixed frame 11.

[0042] Specifically, it is ensured that the rotating threaded rod 10 can move on the L-shaped plate 9 under the action of the thread, and that the threaded rod 10 can rotate normally on the fixed frame 11.

[0043] In this embodiment, the exhaust pipe 3 is tightly welded to the container 1, and the intake pipe 2 is tightly welded to the container 1.

[0044] Among them, it is necessary to ensure the structural stability of the air outlet pipe 3 and the container 1, and to ensure the structural stability of the air inlet pipe 2 and the container 1.

[0045] In this embodiment, valve 5 is tightly welded to container 1, and vent pipe 3 is tightly welded to outer shell 4.

[0046] Among these measures, it is essential to ensure the structural stability of valve 5 and container 1, and to guarantee the structural stability of vent pipe 3 and outer shell 4.

[0047] In this embodiment, the frame 8 is slidably connected to the outer shell 4.

[0048] This ensures that the frame 8 can slide normally within the outer casing 4.

[0049] In this embodiment, the frame 8 is slidably connected to filter plate 13, filter plate 2 14 and filter plate 3 15.

[0050] Specifically, it is ensured that filter plate 13, filter plate 2, and filter plate 3 can slide normally within frame 8.

[0051] In actual operation, when this device is used, the oil and gas mixture generated by the pyrolysis of waste plastics enters the container 1 through the air inlet pipe 2. The air inlet pipe 2 is located on one side of the spiral plate 6. Under the guidance of the spiral plate 6, the oil and gas mixture moves upward along the spiral path. During this process, the oil droplets and gas are initially separated by centrifugal force and gravity. The oil droplets gather on the spiral plate 6 and flow downward along the plate surface. Finally, they are discharged through the valve 5 near the bottom of the container 1, thus achieving the initial collection of oil.

[0052] After initial separation, the gas continues to move upward and is discharged from container 1 through the gas outlet pipe 3. The oil filter screen 7 fixed inside the gas outlet pipe 3 plays a role in further intercepting and filtering the residual oil droplets in the gas, and performing secondary purification of the gas. The relatively pure gas after the first two steps enters the square frame 8 located in the outer shell 4 above container 1. The filter plate 13, filter plate 24 and filter plate 35 installed in the square frame 8 from top to bottom, with different filtration precision and structure, remove tiny oil mist particles and impurities in the gas, and achieve deep separation of oil and gas.

[0053] When cleaning or replacing the filter plates is required, the threaded rod 10 is threadedly connected to the L-shaped plate 9 and rotatably connected to the fixed frame 11. Rotating the threaded rod 10, utilizing its threaded engagement with the L-shaped plate 9, causes the threaded rod 10 to move axially, driving the fixed frame 11 and the square frame 8 to move left and right. Since the square frame 8 is slidably connected to the outer casing 4, it can be easily pulled out of the outer casing 4, facilitating the cleaning or replacement of filter plates 13, 14, and 15 by operators. This ensures the continuous and efficient operation of the device, providing a rapid oil-gas separation device for waste plastic pyrolysis oil with high oil-gas separation efficiency, stable pyrolysis oil quality, high production efficiency, and excellent environmental performance. By optimizing the internal structure, the device enables rapid and thorough separation of oil and gas, thereby improving the quality and production efficiency of the pyrolysis oil. Simultaneously, this device also emphasizes environmental performance, ensuring that the discharged gas does not contain harmful substances, effectively avoiding environmental pollution and health risks to operators.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
