[0002] Petroleum development refers to the process of obtaining petroleum resources through exploration, extraction, and production. After petroleum is extracted from the ground, crude oil contains a certain amount of water, which needs to be removed using physical or chemical methods in a free or emulsion state to bring its water content down to a specified standard. A search revealed a patent with publication number CN223176065U, which discloses a crude oil dehydration device. This device provides a stable reaction space through a support device and mixes the crude oil using a stirring device, which facilitates the dispersion of demulsifiers, demetallizing agents, and injected water. A sealing device covers the port of the support device to prevent liquid from splashing out during the stirring process and polluting the operating environment, thus improving the device's practicality. The device includes a support device, a stirring device, and a sealing device, with the stirring device and sealing device mounted on the support device. However, the aforementioned patent has the following shortcomings: it can only dehydrate crude oil intermittently, making continuous dehydration inconvenient, and the dehydration efficiency is low. Therefore, we propose a crude oil dehydration device for petroleum development. Summary of the Invention

Each arc-shaped oil guide pipe has an installation groove inside, and an arc-shaped electric heating plate is installed inside the installation groove. Each dehydration tank has an electric heating rod inside its inner cavity. A top cover is hinged to the top of the dehydration tank. A steam exhaust mechanism and a stirring mechanism are provided on the dehydration tank. An oil inlet pipe is fixedly sleeved on one side of the dehydration tank, and an oil outlet pipe is fixedly sleeved on the other side of the dehydration tank.

[0005] In a preferred embodiment of this utility model, the exhaust mechanism includes an air induced draft fan fixedly installed on the back of the dehydration tank.

[0010] Compared with existing technologies, the advantages of this utility model are: In this invention, multiple dehydration tanks are set on the dehydration tank, and an oil passage hole and an arc-shaped oil guide pipe are set between two adjacent dehydration tanks. Crude oil is introduced into the first dehydration tank from the oil inlet pipe. The crude oil flows through the multiple dehydration tanks through the oil passage hole and the arc-shaped oil guide pipe. The crude oil located in the inner cavity of the dehydration tank is heated by an electric heating rod.

[0017] like Figures 1 to 4 As shown, a crude oil dehydration device for petroleum development includes a dehydration tank 1 with multiple dehydration tanks 2. Multiple oil passage holes 3 are provided between every two adjacent dehydration tanks 2. The multiple dehydration tanks 2 are arranged in a stepped pattern from left to right. The oil passage holes 3 are located in the middle of the inner side of the dehydration tank 2, ensuring that crude oil can enter the next dehydration tank 2 through the oil passage holes 3 under its own gravity. The crude oil is heated by electric heating rods 13, which melts the crude oil to ensure its smooth flow and separates the water in the crude oil into water vapor. Multiple arc-shaped oil guide pipes 4 are fixedly connected to the inner walls of the multiple dehydration tanks 2. The multiple arc-shaped oil guide pipes 4 are concentrically arranged with the oil passage holes 3. Each arc-shaped oil guide pipe 4 has an installation groove 5 inside, and an arc-shaped electric heating plate 6 is installed inside the installation groove 5. Electric heating rods 13 are installed inside the inner cavities of the dehydration tanks 2. The top of the dehydration tank 1 is hinged. The dehydration tank 1 is equipped with a top cover 8, a steam exhaust mechanism 9, and an agitation mechanism 7. An oil inlet pipe 10 is fixedly connected to one side of the dehydration tank 1, through which the crude oil to be dehydrated is introduced into the foremost dehydration tank 2. An oil outlet pipe 11 is fixedly connected to the other side of the dehydration tank 1, through which the dehydrated crude oil in the last dehydration tank 2 is discharged. The agitation mechanism 7 includes a geared motor 20 fixedly installed on the outside of the dehydration tank 1. The output shaft of the geared motor 20 extends into the inner cavity of the dehydration tank 2 and is fixedly connected to a stirring rod 21 through a coupling. Multiple stirring plates 22 are fixedly connected to the side of the stirring rod 21. The geared motor 20 drives the stirring rod 21 and the stirring plates 22 to rotate, and the stirring plates 22 agitate the crude oil in the inner cavity of the other dehydration tanks 2 except for the two front and rear dehydration tanks 2, so as to ensure that the heating rod 13 can heat the crude oil evenly. Example

[0018] Based on Example 1, such as Figure 1 and Figure 2 As shown, the exhaust mechanism 9 includes an air induced draft fan 14 fixedly installed on the back of the dehydration tank 1. The input end of the air induced draft fan 14 is fixedly connected to a steam extraction pipe 15. The end of the steam extraction pipe 15 is fixedly connected to a steam collecting pipe 16. The bottom surface of the steam collecting pipe 16 is fixedly connected to multiple steam guiding pipes 17. The bottom ends of the multiple steam guiding pipes 17 are all fixedly connected to a steam extraction hood 18. The bottom ends of the multiple steam extraction hoods 18 are all fixedly sleeved on the top cover 8. The multiple steam extraction hoods 18 are respectively located above the multiple dehydration tanks 2. The output end of the air induced draft fan 14 is fixedly connected to an exhaust pipe 19. The air induced draft fan 14 generates suction force through the steam extraction pipe 15, the steam collecting pipe 16, the steam guiding pipe 17 and the steam extraction hood 18, thereby extracting the water vapor separated from the inner cavity of the multiple dehydration tanks 2. Example

[0019] Based on Embodiment 1 and Embodiment 2, such as Figures 1 to 4As shown, multiple drain valves 24 are fixedly sleeved on the side of the dehydration tank 1. The ends of the multiple drain valves 24 extend to the bottom of the inner cavity of the dehydration tank 2. The multiple drain valves 24 are used to discharge the separated water in the lower part of the inner cavity of the dehydration tank 2. A viewing plate 23 is provided on the side of the dehydration tank 1 and outside the dehydration tank 2. The viewing plate 23 is used to control the water volume in the lower part of the inner cavity of the dehydration tank 2 so that the water can be discharged from the drain valves 24 in a timely manner. A control panel 25 is fixedly installed on the outside of the dehydration tank 1. The control panel 25 is electrically connected to the geared motor 20, the electric heating rod 13, the arc-shaped electric heating plate 6, and the air induced draft fan 14. The control panel 25 is used to control the geared motor 20, the electric heating rod 13, the arc-shaped electric heating plate 6, and the air induced draft fan 14, and the power supply of the control panel 25, the geared motor 20, the electric heating rod 13, the arc-shaped electric heating plate 6, and the air induced draft fan 14 is used. This is the prior art.

[0020] It should be noted that this utility model is a crude oil dehydration device for petroleum development. In use, the heating rod 13 is first energized to generate heat on its outer side, and simultaneously, the arc-shaped heating plate 6 inside the arc-shaped oil guide pipe 4 is energized to generate heat. The arc-shaped oil guide pipe 4 generates heat in the arc-shaped heating plate 6. At the same time, the reduction motor 20 is started, driving the stirring rod 21 and stirring plate 22 to rotate within the dehydration tank 2. Then, the extracted crude oil is introduced from the inlet pipe 10 into the inner cavity of the first dehydration tank 2. The heating rod 13 within the dehydration tank 2 heats the crude oil, causing some of the water in the crude oil to evaporate. Simultaneously, the remaining water, under its own gravity, moves to the bottom of the inner cavity of the dehydration tank 2, where it is separated by the density difference between the crude oil and water. Then, when the crude oil level is higher than the level of the oil passage hole 3, the crude oil passes through the oil passage hole 3 and the arc-shaped oil guide pipe 4 into the inner cavity of the next dehydration tank 2. At this point, the heat from the arc-shaped oil guide pipe 4 is used to further heat the crude oil. The flowing crude oil is heated to further evaporate the water in the crude oil into water vapor. The crude oil falling from the end of the arc-shaped oil guide pipe 4 falls into the lower part of the inner cavity of the dehydration tank 2, and is similarly heated again by the electric heating rod 13, and the oil and water are separated again. At this time, the crude oil is stirred by the stirring plate 22 to ensure the quality of heating of the crude oil by the electric heating rod 13. The crude oil flows in multiple dehydration tanks 2 in this way so that the oil and water can be separated in different dehydration tanks 2. The dehydrated crude oil in the last dehydration tank 2 is discharged through the oil outlet pipe 11. Finally, the water volume at the bottom of multiple dehydration tanks 2 is controlled through the transparent plate 23 so that the drain valve 24 can be opened to discharge the water separated at the bottom of the inner cavity of the dehydration tank 2. In addition, the air induced draft fan 14 is started to generate suction through the steam extraction pipe 15, the steam collecting pipe 16, the steam guide pipe 17 and the steam extraction hood 18. The suction of the steam extraction hood 18 is used to extract the water vapor generated in the inner cavity of multiple dehydration tanks 2 in time.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
