Description

A crude oil-gas separator for oil wells Technical Field

[0001] This utility model relates to the field of separator technology, specifically to a crude oil-gas separator for oil wells. Background Technology

[0002] Oil well oil-gas separators are one of the key pieces of equipment in the oil and gas extraction process. They are used to separate the mixture of crude oil, natural gas and water extracted from the oil well into different components. They are the basic equipment to ensure that each component in the oil and gas processing system is properly processed and are widely used in oil fields, gas fields, offshore platforms and the petrochemical industry.

[0003] However, in the use of existing equipment, the separator is used to effectively separate the three-phase mixture of oil, gas and water. Since the density difference between oil, gas and water is large, gravity is the main force for separating the three phases. However, after long-term operation, the separator may accumulate deposits, which will affect the oil-gas separation effect and make it difficult to meet the requirements of oil-gas separation work. Summary of the Invention

[0004] The purpose of this invention is to provide a crude oil-gas separator for oil wells to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crude oil-gas separator for oil wells, comprising a separator tank, an exhaust pipe, an inlet pipe, and an outlet pipe. A cleaning assembly is provided on the outside of the separator tank. The cleaning assembly includes a shell, one end of which is disposed inside the separator plate. A groove is opened inside the one end of the shell. The outside of the separator plate is fixedly installed on the inner wall of the separator tank. A first spiral rod and a second spiral rod are provided inside the shell.

[0006] As a further preferred embodiment of this technical solution, one end of the first screw rod is fixedly connected to a first gear, and the outer side of the first gear is meshed with the outer side of the second gear.

[0007] As a further preferred embodiment of this technical solution, a micro motor is provided at one end of the second gear, and an observation slot is provided at the upper end of the outer casing.

[0008] As a further preferred embodiment of this technical solution, a slot is provided at the lower end of the outer shell, and one end of the slot corresponds to the interior of the separation plate.

[0009] As a further preferred embodiment of this technical solution, the lower end of the outer casing is provided with an oil tank and a drain outlet.

[0010] As a further preferred embodiment of this technical solution, the upper end of the separation plate is in contact with a cleaning brush plate.

[0011] As a further preferred embodiment of this technical solution, one end of the cleaning brush plate is fixedly connected to the outside of the rotating shaft, and a servo motor is installed at the upper end of the rotating shaft.

[0012] This utility model provides a crude oil-gas separator for oil wells, which has the following advantages:

[0013] This invention increases the flow path and residence time of crude oil within the separator tank by allowing it to flow through the through holes of the separator plate. This helps to further separate the residual fine oil and gas. After separation, a servo motor drives a cleaning brush plate to rotate, which promptly removes impurities adhering to the separator plate. This prevents impurity accumulation from affecting the flow of the through holes and the separation efficiency. A micro motor drives the first and second spiral rods to work together, transporting the brushed-off impurities and discharging them from the outlet. Simultaneously, residual crude oil is discharged from the oil tank and flows through the slots to the next separator plate, preventing the separator from accumulating deposits during long-term operation and thus avoiding any impact on the oil and gas separation effect.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: As shown in Figures 1-4, in this embodiment, a crude oil gas separator for oil wells includes a separator tank 100, an exhaust pipe 101, an inlet pipe 102, and an outlet pipe 103. A cleaning component 200 is provided on the outside of the separator tank 100. The cleaning component 200 includes a housing 205, one end of which is disposed inside the separator plate 203. A slot is formed inside the one end of the housing 205. The outer side of the separator plate 203 is fixedly installed on the inner wall of the separator tank 100. The inside of the housing 205 is provided with... The device includes a first spiral rod 206 and a second spiral rod 210. One end of the first spiral rod 206 is fixedly connected to a first gear 208. The outer side of the first gear 208 is meshed with the outer side of a second gear 209. One end of the second gear 209 is equipped with a micro motor 211. The upper end of the housing 205 is provided with an observation groove 207. The lower end of the housing 205 is provided with a slot 214. One end of the slot 214 corresponds to the inside of the separation plate 203. The lower end of the housing 205 is provided with an oil tank 212 and a discharge port 213.

[0021] As shown in Figure 2, the upper end of the separation plate 203 contacts the cleaning brush plate 204, one end of the cleaning brush plate 204 is fixedly connected to the outside of the rotating shaft 202, and the upper end of the rotating shaft 202 is equipped with a servo motor 201.

[0022] In this scheme, crude oil enters the separator 100 through the inlet pipe 102. Inside the separator 100, due to the lower density of oil and gas, the oil rises while the crude oil remains at the bottom. Gas is discharged through the exhaust pipe 101, and then crude oil is discharged through the outlet pipe 103. The crude oil flows downward through the through holes of the separator plate 203. After the oil-gas separation process is completed, the servo motor 201 starts, driving the rotating shaft 202 to rotate. The cleaning brush plate 204, which is fixedly connected to the outside of the rotating shaft 202, rotates accordingly. The cleaning brush plate 204 contacts the upper end of the separator plate 203, cleaning the surface of the separator plate 203 during rotation and removing any adhering substances. Impurities on the separating plate 203 are brushed off, while other impurities are brushed into the groove at one end of the outer casing 205. The micro motor 211 starts, driving the second gear 209 to rotate. Since the second gear 209 meshes with the first gear 208, the first gear 208 rotates accordingly, thereby driving the first screw rod 206 to rotate. The first screw rod 206 and the second screw rod 210 work together to transport the impurities and discharge them from the outlet 213. The residual crude oil is discharged from the oil tank 212 and flows through the slot 214 to the next separating plate 203.

[0023] In this embodiment, by having crude oil flow through the through holes of the separator plate 203, the flow path and residence time of crude oil in the separator tank 100 are increased, which helps to further separate the residual fine oil and gas. After separation, the servo motor 201 drives the cleaning brush plate 204 to rotate, which can promptly clean the impurities attached to the separator plate 203. This avoids the accumulation of impurities affecting the flow of the through holes of the separator plate 203 and the separation efficiency. The micro motor 211 drives the first screw rod 206 and the second screw rod 210 to work together to transport the brushed impurities and discharge them from the outlet 213. At the same time, the residual crude oil is discharged from the oil tank 212 and continues to flow to the next separator plate 203 through the slot hole 214, avoiding the accumulation of deposits in the separator during long-term operation and preventing the oil and gas separation effect from being affected.

[0024] This utility model provides a crude oil-gas separator for oil wells. Its working principle is as follows: Crude oil enters the separator tank 100 through the inlet pipe 102. Inside the separator tank 100, due to the lower density of oil and gas, they rise, while the crude oil remains at the bottom. Gas is discharged through the exhaust pipe 101, and crude oil is discharged through the outlet pipe 103. The crude oil flows downwards through the through-hole of the separator plate 203. After the oil-gas separation process is completed, the servo motor 201 starts, driving the rotating shaft 202 to rotate. The cleaning brush plate 204, fixedly connected to the outside of the rotating shaft 202, rotates accordingly. The cleaning brush plate 204 contacts the upper end of the separator plate 203, and cleans the separator plate 203 during rotation. 03. The surface is cleaned to remove impurities adhering to the separating plate 203. Other impurities are brushed into the groove at one end of the outer shell 205. The micro motor 211 starts, driving the second gear 209 to rotate. Since the second gear 209 meshes with the first gear 208, the first gear 208 rotates accordingly, thereby driving the first screw rod 206 to rotate. The first screw rod 206 and the second screw rod 210 work together to transport the impurities and discharge them from the outlet 213. The residual crude oil is discharged from the oil tank 212 and continues to flow through the slot 214 from the groove at one end of the outer shell 205 of the separating plate 203 to the next separating plate 203. The separating plate 203 divides the interior of the separating tank into multiple spaces. After the crude oil and oil-gas mixture enter the separating tank, under the action of gravity, the oil-gas moves upward due to its lower density, and the crude oil moves downward due to its higher density. The through holes on the separating plate 203 allow the crude oil to gradually flow downward under the action of gravity. In this process, the oil-gas and crude oil are continuously separated by gravity.
