Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil-gas separator technology, and in particular to an oil-gas separator for oil-gas transmission pipelines. Background Technology
[0002] Oil-gas mixtures typically consist of petroleum and natural gas, which have different physical and chemical properties. Petroleum is a viscous liquid, while natural gas is a gaseous mixture of hydrocarbons. An oil-gas separator is a device used to separate oil-gas mixtures and plays a crucial role in oil-gas transmission pipelines.
[0003] Traditional oil-gas separators mostly require power equipment to drive them, such as centrifugal separation. The operation of power equipment consumes a lot of energy, which increases the operating cost of oil-gas separators.
[0004] Therefore, those skilled in the art have provided an oil-gas separator for oil and gas transmission pipelines to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil-gas separator for oil-gas transmission pipelines. When oil and gas enter the gravity separation pipe through the inlet pipe, the oil and gas first enter the first fixed cylinder with a closed top. Since the oil in the flue gas is heavier than the gas, it adheres to the inner wall of the first fixed cylinder upon impact and slides down under gravity. Simultaneously, the remaining flue gas is transmitted through the pipeline to three second fixed cylinders to achieve oil-gas separation in the same way. The separation of oil and gas is achieved through the action of obstruction and gravity. This separation method does not require other power equipment, greatly reducing the operating cost.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An oil-gas separator for an oil-gas transmission pipeline includes an upper shell and a lower shell, which are connected by multiple connecting bolts. A gravity separation pipe is integrally provided on one side of the top of the upper shell, and an air inlet pipe is integrally provided on one end of the gravity separation pipe. A semi-circular plate is integrally provided inside the gravity separation pipe. A first fixed cylinder is welded to the top of the semi-circular plate and the tail end of the air inlet pipe. Three second fixed cylinders are connected to one side of the first fixed cylinder through pipes. The top of the first fixed cylinder is sealed, and the tops of the three second fixed cylinders are open. Fixed pipes are welded to the bottom ends of the first fixed cylinder and the three second fixed cylinders.
[0008] With the above technical solution, when oil and gas enter the gravity separation pipe through the inlet pipe, the oil and gas will first enter the first fixed cylinder with the top closed. Since the oil in the flue gas is heavier than the gas, it will adhere to the inner wall of the first fixed cylinder when it hits it, and then slide down under the action of gravity. At the same time, the remaining flue gas is transmitted through the pipe to the three second fixed cylinders to achieve oil and gas separation in the same way. The oil and gas are discharged through the openings at the top of the three fixed cylinders, and then enter the shell through the notch next to the semi-circular plate inside the gravity separation pipe. The separation of oil and gas is achieved by the action of obstruction and gravity. This separation method does not require other power equipment, which greatly reduces the operating cost.
[0009] Furthermore, an exhaust pipe is integrally provided at one end of the top of the upper shell, and a connecting pipe is connected to the top flange of the exhaust pipe. Both the inner walls of the connecting pipe and the exhaust pipe are welded with partitions, and a defoaming screen is inserted between the two partitions.
[0010] Through the above technical solution, the defoaming screen installed between the exhaust pipe and the connecting pipe can separate the small oil droplets mixed in the oil and gas, causing them to condense into larger oil droplets and sink, thus further improving the oil and gas separation effect. In addition, the exhaust pipe and the connecting pipe are designed with a detachable flange, which facilitates the cleaning and replacement of the defoaming screen in the later stage.
[0011] Furthermore, an oil drain pipe is welded to the bottom end of the lower housing, and a control valve is installed at the outlet end of the oil drain pipe;
[0012] The above technical solution involves welding an oil drain pipe to the bottom of the lower housing and installing a control valve at the outlet of the oil drain pipe to facilitate the discharge of the separated oil.
[0013] Furthermore, a pressure relief pipe is welded to the middle of the top of the upper housing, a pressure relief valve is installed at one end of the pressure relief pipe, and a pressure gauge is installed at the top of the upper housing;
[0014] The above technical solution involves welding a pressure relief pipe to the top center of the upper shell and installing a pressure relief valve at one end of the pipe. This allows the pressure relief valve to be opened to release pressure inside the device when the pressure gauge reading is too high, thereby improving the safety performance of the device.
[0015] Furthermore, multiple folding plates are welded to the inner walls of both the upper and lower shells;
[0016] The above technical solution involves welding multiple baffles onto the inner walls of both the upper and lower shells to block oil and gas, thereby reducing the oil content in the oil and gas.
[0017] Furthermore, support frames are installed on both sides of the bottom end of the lower housing;
[0018] With the above technical solution, support frames are installed on both sides of the bottom of the lower shell to facilitate the support of the entire device.
[0019] This utility model has the following beneficial effects:
[0020] 1. This utility model proposes an oil-gas separator for an oil-gas transmission pipeline. When oil and gas enter the gravity separation pipe through the inlet pipe, the oil and gas first enter the first fixed cylinder with the top closed. Since the oil in the flue gas is heavier than the gas, it will adhere to the inner wall of the first fixed cylinder when it hits it, and then slide down under the action of gravity. At the same time, the remaining flue gas is transmitted through the pipeline to three second fixed cylinders to achieve oil-gas separation in the same way. The oil and gas are discharged through the openings at the top of the three fixed cylinders, and then enter the shell through the notch next to the semi-circular plate inside the gravity separation pipe. The separation of oil and gas is achieved by the action of obstruction and gravity. This separation method does not require other power equipment, which greatly reduces the operating cost.
[0021] 2. The oil-gas separator proposed in this utility model for oil-gas transmission pipelines uses multiple baffles welded to the inner walls of the upper and lower shells to block oil and gas, thereby reducing the oil content in the oil and gas. When the oil and gas are discharged, the defoaming screen installed between the exhaust pipe and the connecting pipe can separate the small oil droplets mixed in the oil and gas, causing them to condense into larger oil droplets and sink, further improving the oil-gas separation effect. In addition, the exhaust pipe and the connecting pipe have a detachable flange design, which facilitates later cleaning and replacement of the defoaming screen. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1-5 This utility model provides an embodiment of an oil-gas separator for an oil-gas transmission pipeline, comprising an upper shell 1 and a lower shell 2, which are connected by multiple connecting bolts 14. A gravity separation pipe 4 is integrally provided on one side of the top of the upper shell 1, and an air inlet pipe 5 is integrally provided on one end of the gravity separation pipe 4. A semi-circular plate 6 is integrally provided inside the gravity separation pipe 4. A first fixing cylinder 7 is welded to the top of the semi-circular plate 6 and the tail end of the air inlet pipe 5. Three second fixing cylinders 8 are connected to one side of the first fixing cylinder 7 via pipes. The top of the first fixing cylinder 7 is sealed, while the tops of the three second fixing cylinders 8 are open. The bottom ends of the first fixing cylinder 7 and the three second fixing cylinders 8 are all welded with... With a fixed pipe 9, when oil and gas enter the gravity separation pipe 4 through the inlet pipe 5, the oil and gas first enter the first fixed cylinder 7, which is closed at the top. Since the oil in the flue gas is heavier than the gas, it will adhere to the inner wall of the first fixed cylinder 7 when it hits it, and then slide down under the action of gravity. At the same time, the remaining flue gas is transmitted through the pipe to the three second fixed cylinders 8 to achieve oil and gas separation in the same way. The oil and gas are discharged through the openings at the top of the three fixed cylinders, and then enter the shell through the notch next to the semi-circular plate 6 inside the gravity separation pipe 4. The separation of oil and gas is achieved by the action of obstruction and gravity. This separation method does not require other power equipment, which greatly reduces the operating cost.
[0031] An exhaust pipe 15 is integrally installed at one end of the top of the upper shell 1. A connecting pipe 16 is connected to the top flange of the exhaust pipe 15. Baffles 17 are welded to the inner walls of both the connecting pipe 16 and the exhaust pipe 15. A defoaming screen 18 is clamped between the two baffles 17. The defoaming screen 18 clamped between the exhaust pipe 15 and the connecting pipe 16 can separate the fine oil droplets mixed in the oil and gas, causing them to condense into larger oil droplets and sink, further improving the oil and gas separation effect. The exhaust pipe 15 and the connecting pipe 16 have a detachable flange design, which facilitates later cleaning and replacement of the defoaming screen 18. An oil drain pipe 11 is welded to the bottom of the lower shell 2. A control valve 12 is installed at the outlet end of the oil drain pipe 11. After separation, the oil is discharged. A pressure relief pipe 13 is welded to the middle of the top of the upper shell 1, and a pressure relief valve 20 is installed at one end of the pressure relief pipe 13. A pressure gauge 19 is installed at the top of the upper shell 1. The pressure relief pipe 13 is welded to the middle of the top of the upper shell 1, and a pressure relief valve 20 is installed at one end of the pressure relief pipe 13. This allows the pressure relief valve 20 to be opened to relieve pressure inside the device when the pressure gauge 19 reading is too high, thereby improving the safety performance of the device. Multiple baffles 10 are welded to the inner walls of both the upper shell 1 and the lower shell 2. These baffles 10 can block oil and gas, thereby reducing the oil content in the oil and gas. Support frames 3 are installed on both sides of the bottom of the lower shell 2 to facilitate the support of the entire device.
[0032] Working principle: When oil and gas enter the gravity separation pipe 4 through the inlet pipe 5, the oil and gas first enter the first fixed cylinder 7, which is sealed at the top. Because the oil in the flue gas is heavier than the gas, it adheres to the inner wall of the first fixed cylinder 7 upon impact and slides down under gravity. Simultaneously, the remaining flue gas is transported through pipes to three second fixed cylinders 8 for oil-gas separation in the same way. The oil and gas are then discharged through the openings at the top of the three fixed cylinders, and then enter the housing through the notch next to the semi-circular plate 6 inside the gravity separation pipe 4. The separation is achieved through obstruction and gravity. This invention achieves oil-gas separation without requiring additional power equipment, significantly reducing operating costs. Multiple baffles 10 welded to the inner walls of the upper and lower shells 1 and 2 can block the oil and gas, thereby reducing the oil content in the oil and gas. When the oil and gas are discharged, a defoaming screen 18 installed between the exhaust pipe 15 and the connecting pipe 16 can separate the fine oil droplets mixed in the oil and gas, causing them to condense into larger oil droplets and sink, further improving the oil-gas separation effect. Furthermore, the exhaust pipe 15 and the connecting pipe 16 have a detachable flange design, facilitating subsequent cleaning and replacement of the defoaming screen 18.
