DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: an oil-gas separation device for an oil-gas transmission pipeline, comprising a separation tank 1, a top plate 2 is slidably connected to the upper end of the inner wall of the separation tank 1, a feed port 28 is opened inside the separation tank 1, a motor 3 is fixedly connected to the top plate 2, a rotating rod 4 is fixedly connected to the driving end of the motor 3, a scraper 1 5 is fixedly connected to the upper end of the outer wall of the rotating rod 4, a scraper 2 6 is fixedly connected to the upper end of the outer wall of the rotating rod 4, a connecting rod 7 is fixedly connected to the lower surface of the top plate 2, and a connecting plate 8 is fixedly connected to the lower surface of the connecting rod 7, The lower surface of the connecting plate 8 is fixedly connected with an oil filter plate 9, and the lower surface of the oil filter plate 9 is in contact with the lower surface of the scraper plate 6. The interior of the connecting plate 8 is fixedly connected with the cooling surfaces of a plurality of semiconductor refrigeration sheets 10, and the heating surfaces of the semiconductor refrigeration sheets 10 are fixedly connected with a plurality of heat sinks 11. A filter assembly is provided at the lower end of the inner wall of the separation tank 1. The filter assembly includes an arc-shaped oil filter plate 12. The outer wall of the arc-shaped oil filter plate 12 is fixedly connected to the inner wall of the separation tank 1, and the upper surface of the arc-shaped oil filter plate 12 is in contact with the lower surface of the scraper plate 5.

[0032] Specifically, the mixture containing oil and gas is injected into the interior of the separation tank 1 through the feed port 28 of the separation tank 1. The function of the feed port 28 is to conveniently introduce the oil and gas mixture into the device. Subsequently, the feed port 28 is closed to allow the oil and gas mixture to form a relatively stable environment in the tank. After closing, the oil and gas mixture will fall downward on the surface of the arc-shaped oil filter plate 12 under the action of gravity. The crude oil falling on the arc-shaped oil filter plate 12 is filtered and separated and then collected at the bottom of the separation tank 1. At this time, the filtered and separated crude oil is discharged by opening the solenoid valve 19. This process is intended to ensure the quality of the crude oil and avoid polluting the environment. After the oil is discharged, the oil filter plate 9 at the bottom of the connecting plate 8 will collect the small oil droplets in the gas. The collected small oil droplets are quickly cooled by the semiconductor refrigeration plate 10, making it easier for the oil droplets to gather. Then, the motor 3 drives the rotating rod 4 to rotate, and the scraper 1 5 and the scraper 2 6 on the rotating rod 4 rotate accordingly. The scraper 1 5 is responsible for cleaning the surface of the arc-shaped oil filter plate 12 to prevent clogging by impurities and ensure the normal operation of the oil filter plate. The scraper 2 6 scrapes the lower surface of the oil filter plate 9 to scrape off the collected crude oil. After being filtered again by the arc-shaped oil filter plate 12, the quality of the crude oil is further improved, thereby improving the collection efficiency and avoiding waste of resources.

[0033] Reference Figure 2-Figure 4 The top plate 2 is fixedly connected to a bilaterally symmetrical exhaust pipe 15, the bottom end of the exhaust pipe 15 is fixedly connected to a connecting pipe 13, the bottom end of the connecting pipe 13 is fixedly connected to a plurality of intake pipes 14, and the inside of the intake pipes 14 are all fixedly connected to filter elements 16;

[0034] Specifically, the mixture containing oil and gas is injected into the interior of the separation tank 1 through the feed port 28 of the separation tank 1. The function of the feed port 28 is to conveniently introduce the oil and gas mixture into the device. Subsequently, the feed port 28 is closed so that the oil and gas mixture forms a relatively stable environment in the tank. After closing, the oil and gas mixture will fall on the surface of the arc-shaped oil filter plate 12 under the action of gravity, and the gas will rise. The rising gas passes through the filter element 16 on the inner wall of the intake pipe 14 for preliminary filtration to remove larger particles therein. The filtered gas enters the exhaust pipe 15 through the connecting pipe 13 and is finally discharged out of the device.

[0035] Reference Figure 1 and Figure 5 The outer wall of the separation tank 1 is fixedly connected with a support plate 20, the upper surface of the support plate 20 is fixedly connected with a storage box 21, the top of the storage box 21 is fixedly connected with a feeding pipe 27, the upper surface of the storage box 21 is fixedly connected with a delivery pump 22, the input end of the delivery pump 22 is fixedly connected with an extraction pipe 23, the outer wall of the extraction pipe 23 is fixedly connected to the inside of the storage box 21, the output end of the delivery pump 22 is fixedly connected with a delivery pipe 24, the outer wall of the delivery pipe 24 is fixedly connected to the inside of the separation tank 1, the outer wall of the delivery pipe 24 is fixedly connected with a diverter pipe 25, the bottom end of the diverter pipe 25 is fixedly connected with a plurality of high-pressure nozzles 26, the outer wall of the diverter pipe 25 is fixedly connected to the inner wall of the separation tank 1, the lower surface of the separation tank 1 is fixedly connected with a bracket 17, the bottom end of the separation tank 1 is fixedly connected with an oil outlet pipe 18, and the oil outlet pipe 18 is provided with a solenoid valve 19;

[0036] Specifically, during the entire process, if the interior of the separation tank 1 needs to be cleaned, it is only necessary to start the delivery pump 22, extract the cleaning liquid inside the storage box 21 through the extraction pipe 23, and then transport the cleaning liquid to the inside of the diversion pipe 25 through the delivery pipe 24 for diversion. Finally, the cleaning liquid is sprayed onto the inner wall of the separation tank 1 using the high-pressure nozzle 26 to clean the inner wall. This can effectively extend the service life of the separation tank 1 and ensure its normal operation.

[0037] Working principle: when the device needs to be used, first inject the oil and gas into the interior of the separation tank 1 through the feed port 28 of the separation tank 1, then block the feed port 28, and let the oil and gas fall onto the surface of the arc-shaped oil filter plate 12 for filtration and separation. The gas rises, and after being filtered by the filter element 16 on the inner wall of the intake pipe 14, it is discharged through the exhaust pipe 15 connected to the connecting pipe 13. The crude oil falls to the bottom of the separation tank 1 through the arc-shaped oil filter plate 12, and the crude oil after filtration and separation is discharged by opening the solenoid valve 19. Then, the small oil droplets in the gas are collected through the oil filter plate 9 at the bottom of the connecting plate 8, and the semiconductor refrigeration sheet 10 is started to quickly cool the inside of the connecting plate 8 to accelerate the gathering of the oil droplets, and then the motor 3 is started to drive the rotating rod 4 to enter The rotating rod 4 rotates, and the scraper 1 5 and the scraper 2 6 are rotated together. The scraper 1 5 cleans the surface of the arc-shaped oil filter plate 12 to prevent impurities from clogging the arc-shaped oil filter plate 12. The scraper 2 6 scrapes the lower surface of the oil filter plate 9 to scrape off the collected crude oil, which is filtered through the arc-shaped oil filter plate 12 to improve the collection efficiency of the crude oil and prevent waste of resources. Finally, when it is necessary to clean the inside of the separation tank 1, the delivery pump 22 is started to extract the cleaning liquid in the storage box 21 through the extraction pipe 23, and then the cleaning liquid is transported to the inside of the diversion pipe 25 through the delivery pipe 24 for diversion, and finally discharged through the high-pressure nozzle 26 to clean the inner wall of the separation tank 1 and increase the service life of the separation tank 1.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
