Description

Technical Field

[0001] The utility model relates to the technical field of crude oil dehydrators, in particular to a crude oil dehydrator. Background Art

[0002] Crude oil dehydration is a basic process requirement in the petroleum industry, aiming to reduce the water content in crude oil. Through equipment, desalting, dehydration, demetallization, and impurity removal of crude oil are completed to meet the needs of subsequent processing and transportation. With the increasing difference in oil reserves in oil fields, traditional dehydration methods include natural sedimentation, heating separation, etc. Crude oil dehydrators have broad application prospects and important significance in the petroleum industry. By effectively reducing the water content in crude oil, the quality and processing efficiency of crude oil can be improved, equipment corrosion and energy consumption losses can be reduced. At the same time, it can also provide a more reliable guarantee for subsequent petroleum refining and transportation.

[0004] However, in actual use, the heating position of the above device is concentrated, and it does not have the ability to keep the whole liquid warm. At the same time, the existing equipment usually adopts a flat bottom, and the flat bottom is easy to cause water residue at the bottom edge during the drainage process, while the equipment with a conical bottom cannot effectively heat and cover the bottom. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a crude oil dehydrator. A stable reaction space is provided by a bearing device, the crude oil is mixed and stirred by a stirring device, which is beneficial to the dispersion of demulsifiers, demetallizing agents, and injected water. The port of the bearing device is sealed by a sealing device to prevent the liquid from splashing out during the operation of the stirring device and polluting the operating environment, thus improving the practicability of the device.

[0006] The crude oil dehydrator of the utility model includes a bearing device, a stirring device, and a sealing device. The stirring device is installed on the bearing device, and the sealing device is installed on the bearing device. A stable reaction space is provided by the bearing device, the crude oil is mixed and stirred by the stirring device, which is beneficial to the dispersion of demulsifiers, demetallizing agents, and injected water. The port of the bearing device is sealed by the sealing device to prevent the liquid from splashing out during the operation of the stirring device and polluting the operating environment, thus improving the practicability of the device.

[0007] Preferably, the carrying device includes a frame, a stainless - steel barrel, fixing brackets, connecting bolts and handles. Multiple groups of fixing brackets are arranged on the side of the stainless - steel barrel. The stainless - steel barrel is placed on the frame through multiple groups of fixing brackets. The fixing brackets are connected to the frame through connecting bolts. Two groups of handles are symmetrically arranged on the upper part of the side of the stainless - steel barrel. The handles provided on the stainless - steel barrel facilitate the handling of the stainless - steel barrel. The stainless - steel barrel is fixed on the frame through the fixing brackets and connecting bolts, reducing the displacement of the stainless - steel barrel caused by its own vibration during the operation of the equipment, and improving the stability and practicability of the device.

Multiple groups of horizontal support rods are horizontally connected to the upper part of the bracket. The stirring motor is fixed on the right part of multiple groups of horizontal support rods. The output end of the stirring motor extends into the stainless - steel barrel. The stirring rod is installed on the output end of the stirring motor. When the stirring motor is started, power is transmitted to the stirring rod to drive the stirring rod to stir and mix the liquid in the stainless - steel barrel, thereby realizing the desalting, dehydration, demetallization and impurity removal of crude oil, etc., improving the dispersion efficiency of demulsifiers, demetallizing agents and injected water and the production efficiency of the equipment.

[0009] Preferably, the sealing device includes a semi - circular end cover, a connecting plate, a liquid guide groove, a rotating shaft and a buckle. Two groups of semi - circular end covers are installed on the upper port of the stainless - steel barrel.

The buckles are connected to the stainless - steel barrel through rotating shafts. The two groups of semi - circular end covers are connected through the connecting plates and bolts, facilitating the installation and removal of the semi - circular end covers on the stainless - steel barrel. The positions of the two groups of semi - circular end covers are fixed through the cooperation of the rotating shafts and buckles, reducing the displacement of the semi - circular end covers caused by the vibration of the equipment during the processing. The liquid splashed on the bottom end face of the semi - circular end cover during the processing is guided through the liquid guide groove, so that the liquid drips at the bottom of the liquid guide groove, preventing the liquid from flowing to the arc edge of the semi - circular end cover and overflowing from the gap between the semi - circular end cover and the stainless - steel barrel, improving the practicability and stability of the device.

A liquid discharge port is arranged on the lower end face of the conical bottom, and a valve is installed on the liquid discharge port. The conical bottom at the lower part of the stainless - steel barrel reduces the residual amount of materials inside the stainless - steel barrel during the material discharge process. The heat - insulating cotton keeps the liquid in the lower part of the stainless - steel barrel warm, reducing heat loss, and cooperates with the stirring device to make the heat evenly distributed inside the stainless - steel barrel. The valve controls the liquid discharge switch, improving the practicability of the device.

[0011] Preferably, it further includes a stainless steel plate, a heating tape, and a liquid level sensor. The side of the stainless steel barrel is wrapped with a stainless steel plate.

And multiple groups of heating tapes are wound around the outer surface of the conical bottom from top to bottom. A liquid level sensor is vertically installed on the inner side wall of the stainless steel barrel. The liquid level sensor and multiple groups of heating tapes are connected to the controller. The stainless steel plate provides protection for multiple groups of stirring rods. The liquid level in the stainless steel barrel is monitored by the liquid level sensor, and the data is transmitted to the equipment controller. The controller controls the heating tapes below the liquid level to turn on according to the liquid level height to heat the liquid in the stainless steel barrel, reducing the waste of electric energy during the operation of the equipment. By winding the heating tape on the conical bottom, the bottom heating effect is increased, preventing the situation of solidification and blockage caused by uneven heating of the crude oil in the conical bottom, and improving the practicability of the device.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: A stable reaction space is provided by the loading device.
