Description

Technical Field

[0001] This utility model relates to the technical field of gas-liquid separation and treatment equipment, specifically, a gas-liquid separation device. Background Technology

[0002] Existing oil-gas separators typically include a cylinder and a cylindrical oil separator core housed within the cylinder. The oil-gas mixture is then fed into the cylinder and flows through the oil separator core, resulting in oil-gas separation. However, separation structures using oil separator cores are relatively complex, and the separation effect deteriorates as the core becomes clogged, leading to a relatively short equipment lifespan and high maintenance costs. Utility Model Content

[0003] In view of the above-mentioned technical defects, this utility model provides a gas-liquid separation device, which aims to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a gas-liquid separation device, including a cylinder, a gas-liquid inlet pipe provided on the upper part of the outer wall of the cylinder, a double-cavity vortex section for gas inlet provided on the upper inner part of the cylinder, the double-cavity vortex section for gas inlet having an inner cavity and an outer cavity, a double-cavity liquid collection section provided on the lower inner end of the cylinder, an exhaust pipe connected to the inner cavity provided on the upper end of the cylinder, the gas-liquid inlet pipe connected to the outer cavity, and the outer cavity surrounding the outer side of the inner cavity.

[0005] In the above-mentioned gas-liquid separation device, the cylinder body has a cylinder cavity, the air inlet dual-cavity vortex section includes a baffle ring located at the upper end of the cylinder cavity, the lower end of the baffle ring is an open end, the inner cavity is formed inside the baffle ring, and the outer cavity is formed between the outer wall of the baffle ring and the inner wall of the cylinder cavity.

[0006] In the aforementioned gas-liquid separation device, a slit is provided on the upper part of the inner wall of the outer cavity, and the gas-liquid inlet pipe is connected to the slit. The gas-liquid inlet pipe is located on the tangent of the outer wall of the cylinder.

[0007] In the aforementioned gas-liquid separation device, the dual-chamber liquid collection section includes a first funnel and a second funnel, which are arranged vertically and form a secondary liquid storage chamber between them. The lower end of the second funnel is provided with a drain pipe that communicates with the secondary liquid storage chamber.

[0008] In the aforementioned gas-liquid separation device, a support frame is provided at the lower end of the cylinder.

[0009] In the aforementioned gas-liquid separation device, a filter element is filled inside the retaining ring.

[0010] In the aforementioned gas-liquid separation device, one end of the exhaust pipe extends into the inner cavity and forms a protrusion, the height of the protrusion of the exhaust pipe in the inner cavity being 1-2 cm.

[0011] The beneficial effects of this utility model are as follows: By setting up a dual-chamber vortex section for air intake, the gas-liquid mixture entering the cylinder can vortex in the outer cavity of the dual-chamber vortex section, so that the gas and liquid can undergo the first oil-gas separation, thereby ensuring that the gas discharged from the cylinder contains less liquid. At the same time, due to the setting of a dual-chamber liquid collection section, the separated water and oil are separated in the dual-chamber liquid collection section for easy collection. The structure of the entire device is relatively simple, the service life is long, and the maintenance cost is low. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] Combination Figure 1 and Figure 2 The gas-liquid separation device shown includes a cylinder 1. A gas-liquid inlet pipe 3 is provided on the upper part of the outer wall of the cylinder 1. An air inlet dual-cavity vortex section is provided on the upper inner part of the cylinder 1. The air inlet dual-cavity vortex section has an inner cavity 8 and an outer cavity. A dual-cavity liquid collection section is provided at the lower inner end of the cylinder 1. An exhaust pipe 4 connected to the inner cavity 8 is provided at the upper end of the cylinder 1. The gas-liquid inlet pipe 3 is connected to the outer cavity, and the outer cavity is arranged around the outside of the inner cavity 8. The air inlet dual-cavity vortex section provided in this embodiment allows the gas-liquid mixture entering the cylinder 1 to vortex in the outer cavity of the air inlet dual-cavity vortex section, so that the gas and liquid undergo the first oil-gas separation, thereby ensuring that the gas discharged from the cylinder 1 contains less liquid. At the same time, due to the provision of the dual-cavity liquid collection section, the separated water and oil are separated in the dual-cavity liquid collection section for separate collection. The structure of the entire device is relatively simple, the service life is long, and the maintenance cost is low.

[0017] It is worth noting that, in this embodiment, one end of the exhaust pipe 4 extends into the inner cavity 8 and forms a protrusion, and the height of the protrusion of the exhaust pipe 4 in the inner cavity 8 is 1-2 cm.

[0018] Specifically, in this embodiment, the cylinder 1 has a cylinder cavity 6, and the air inlet dual-cavity vortex section includes a baffle ring 7 located at the upper end of the cylinder cavity 6. The lower end of the baffle ring 7 is an open end, and an inner cavity 8 is formed inside the baffle ring 7. An outer cavity is formed between the outer wall of the baffle ring 7 and the inner wall of the cylinder cavity 6. After the gas-liquid mixture is introduced into the gas-liquid inlet pipe 3, the gas-liquid mixture flows around in the outer cavity, causing the heavier liquid particles to fall into the dual-cavity liquid collection section for storage, while the gas enters from the open end of the baffle ring 7 and is discharged from the exhaust pipe 4.

[0019] It is worth noting that, in order to allow the gas-liquid mixture to flow around after entering the outer cavity, a cutout 9 is provided on the upper part of the inner wall of the outer cavity. The gas-liquid inlet pipe 3 is connected to the cutout 9. The gas-liquid inlet pipe 3 is located on the tangent of the outer wall of the cylinder 1, so that the gas-liquid mixture enters the inner wall of the outer cavity from the tangential direction, and the gas-liquid mixture flows around in the outer cavity.

[0020] The gas-liquid separation principle mentioned in this embodiment is as follows: After the gas-liquid mixture enters through the tangential inlet, it is forced to rotate at high speed along the spiral path. Since the liquid density is much greater than that of the gas, under the action of centrifugal force, the liquid droplets are thrown towards the inner wall of the cylinder 6 and the outer wall of the baffle ring 7 and form a liquid film, while the less dense gas is concentrated in the central area.

[0021] The dual-chamber liquid collection unit of this embodiment includes a first funnel 10 and a second funnel 11, which are arranged vertically and form a secondary liquid storage chamber between them. The lower end of the second funnel 11 is provided with a drain pipe 5 that communicates with the secondary liquid storage chamber. The liquid is collected through the first funnel 10, so that the liquid enters the secondary liquid storage chamber from the first funnel 10. Since the airflow in the secondary liquid storage chamber has less impact, when there is water or oil of different densities in the liquid, the water and oil in the secondary liquid storage chamber can be separated better, thereby improving the separation effect of liquid media of different densities.

[0022] In this embodiment, a support frame 2 is provided at the lower end of the cylinder 1 so that the drain pipe 5 is suspended in the air, making it convenient to operate the drain.

[0023] It is worth noting that in some other embodiments, a filter element may be filled inside the baffle ring 7 so that the gas is filtered before being discharged, thereby reducing impurities carried by the gas during discharge.

[0024] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
