Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separator technology, and in particular to a baffle-type gas-liquid separator. Background Technology

[0002] Gas-liquid separators can capture liquid droplets entrained in gas and output dry, clean gas and pure liquid without cavitation or foaming.

[0003] To improve the separation efficiency of gas-liquid mixtures within a container, gas-liquid separators are designed in a long cylindrical shape to extend the airflow path and increase the separation time. However, the length of a long cylindrical gas-liquid separator is typically 3 to 8 times its diameter, resulting in a large footprint and poor space adaptability. Furthermore, an excessively long separator creates a large bottom area that can easily accumulate liquid, preventing timely drainage and allowing the liquid separated from the gas to be re-entrained by the airflow, thus affecting the gas-liquid separation efficiency.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a baffled gas-liquid separator to reduce the axial length of the gas-liquid separator.

[0006] The technical solution of this utility model is as follows: The baffle-type gas-liquid separator includes a shell, a gas-distributing cylinder, baffle plates, and a baffle shroud disposed within the shell. A liquid drain port is located at the bottom of the shell, and an exhaust port is located at the top. An air inlet is also located on the shell, connecting to the gas-distributing cylinder. Mesh openings are provided on both horizontal sides of the gas-distributing cylinder. The baffle plates are vertically positioned, each with its own mesh opening. Baffle plates are also located on opposite horizontal radial sides of the gas-distributing cylinder. The baffle shroud opens downwards and covers the exhaust port. The opening of the baffle shroud is located directly above the gas-distributing cylinder.

[0007] A further technical solution involves staggering the mesh openings on adjacent baffles.

[0008] A further technical solution is that, towards the side closer to the exhaust port, the cross-section of the cavity inside the horizontal cross-section of the inner and outer shell gradually decreases.

[0009] A further technical solution is that the outer diameter of the baffle in the horizontal cross-section gradually decreases towards the side closer to the gas equalizer.

[0010] A further technical solution involves the addition of an air intake pipe. The air intake pipe connects to the outer casing along the air inlet. A buffer plate is installed inside the air intake pipe.

[0011] A further technical solution involves a buffer plate rotatably connected to the intake pipe. The rotation axis of the buffer plate is set perpendicular to the axis of the intake pipe.

[0012] A further technical solution involves installing a gate valve housing on the intake pipe. A sliding gate is slidably mounted inside the gate valve housing. The sliding direction of the sliding gate is perpendicular to the axis of the intake pipe.

[0013] A further technical solution involves installing a telescopic assembly on the gate valve body. The movable end of the telescopic assembly is connected to the sliding gate.

[0014] A further technical solution is that a through hole is provided on the sliding gate plate.

[0015] A further technical solution is that a demister can be installed inside the baffle.

[0016] The beneficial technical effects of this utility model are as follows: (1) The baffle-type gas-liquid separator of this utility model is equipped with a gas equalization cylinder. After the gas is diverted through several mesh holes on the gas equalization cylinder, it is sprayed onto the baffle plate, making the gas distribution on the baffle plate more uniform and avoiding local airflow turbulence from affecting the separation effect. Moreover, the mesh holes on the gas equalization cylinder are opened along the radial direction of the gas equalization cylinder, and the baffle plate is also set on both horizontal sides of the gas equalization cylinder. The gas is sprayed out radially along the gas equalization cylinder, then diffuses and accumulates upward, and is discharged from the shell through the opening of the baffle hood. In this process, the gas moves radially around the axis of the air inlet and the gas equalization cylinder, occupying less axial space. Therefore, the length dimension of the baffle-type gas-liquid separator in this application accounts for a small proportion of the overall size. In the horizontal direction, the cross-section of the baffle-type gas-liquid separator in this application is closer to a rectangle, which is convenient for placement and does not easily generate a liquid accumulation blind zone at the bottom.

[0017] (2) Furthermore, the mesh openings on adjacent baffles are staggered, which makes the flow path of gas and liquid bend when passing through adjacent baffles, prolongs the gas flow path, increases the separation time of gas-liquid mixture, and improves the gas-liquid separation effect.

[0018] (3) Further, towards the side closer to the exhaust port, the cross-section of the internal cavity of the inner shell gradually decreases, while the outer diameter of the baffle gradually increases. The gradually decreasing cross-section of the cavity facilitates the rising gas approaching the exhaust port, and the rising gas interferes with the shell, making it easier for liquid droplets in the gas to adhere to the shell. The gradually increasing outer diameter of the baffle, i.e., the baffle is truncated cone-shaped, reduces the size of the baffle opening, and prevents gases that have not yet completed separation from being discharged along the baffle, thus affecting the gas-liquid separation effect.

[0025] Figure 1 A three-dimensional structural schematic diagram of a baffle-type gas-liquid separator according to an embodiment of the present disclosure is shown. Figure 2 A three-dimensional structural schematic diagram of a baffle-type gas-liquid separator according to an embodiment of the present disclosure is shown, including a buffer plate, a gate valve housing, and a gas equalization cylinder. Figure 3 A vertical cross-sectional schematic diagram of a baffle-type gas-liquid separator according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3The baffle-type gas-liquid separator includes a shell 2, a gas equalization cylinder 4, baffle plates 5, and a baffle hood 6 disposed within the shell 2. A drain port is located at the bottom of the shell 2, and an exhaust port 22 is located at the top. The drain port is connected to a drain pipe 21, and the exhaust port 22 is connected to a compression fitting. An air inlet is also provided on the shell 2, connecting to the gas equalization cylinder 4. Mesh openings 41 are provided on both horizontal sides of the gas equalization cylinder 4. The baffle plates 5 are vertically arranged and have mesh openings 41. Baffle plates 5 are arranged on opposite horizontal radial sides of the gas equalization cylinder 4. One or more baffle plates 5 can be arranged on one side; this application does not limit this. Gas is diverted through several mesh openings 41 on the gas equalization cylinder 4 and then sprayed onto the baffle plates 5, making the gas distribution more uniform and avoiding local airflow turbulence that could affect the separation effect. The baffle hood 6 faces downwards and covers the exhaust port 22. The opening of the baffle hood 6 is located directly above the gas equalization cylinder 4. The gas is ejected radially from the gas distribution cylinder 4, then diffuses and accumulates upwards, exiting the outer casing 2 through the opening of the baffle 6. During this process, the gas moves radially around the axis of the inlet and the gas distribution cylinder 4, occupying less axial space. Therefore, the length of the baffle-type gas-liquid separator in this application accounts for a smaller proportion of its overall size. In the horizontal direction, the cross-section of the baffle-type gas-liquid separator in this application is closer to a rectangle, facilitating placement and reducing the likelihood of liquid accumulation blind spots at the bottom. In some embodiments, the baffle plate 5 and the outer casing 2, as well as the baffle 6 and the outer casing 2, can be connected by welding.

[0026] Please refer to Figure 2 and Figure 3 The mesh openings 41 on adjacent baffles 5 are staggered. This causes the flow path of gas and liquid to bend when passing through adjacent baffles 5, prolonging the airflow path, increasing the separation time of the gas-liquid mixture, and improving the gas-liquid separation effect.

[0027] Preferably, towards the side near the exhaust port 22, the cross-section of the cavity inside the outer casing 2 gradually decreases. This gradual decrease in cavity cross-section facilitates the rising gas approaching the exhaust port 22, and the rising gas interferes with the outer casing 2, allowing liquid droplets within the gas to adhere to the outer casing 2. More preferably, the outer diameter of the baffle 6 in the horizontal cross-section gradually decreases towards the side closer to the gas equalizer 4. The outer diameter of the baffle 6 gradually decreases, that is, the baffle 6 is in the shape of a frustum, which reduces the size of the opening of the baffle 6 and prevents gases that have not yet been separated from being discharged along the baffle 6, thus affecting the gas-liquid separation effect.

[0028] Please refer to Figure 2 and Figure 3 It is also equipped with an air inlet pipe 1. The air inlet pipe 1 connects to the outer casing 2 along the air inlet. A buffer plate 11 is installed inside the air inlet pipe 1. The gas is confined and impacts the buffer plate 11 to reduce the flow velocity, and the buffer plate 11 hinders the gas flow along the air inlet pipe 1, increasing the width of the gas flow channel and the number of turns, thereby improving the flexibility of the entire baffle-type gas-liquid separator.

[0029] Preferably, the buffer plate 11 is rotatably connected to the air inlet pipe 1. The rotation axis 12 of the buffer plate 11 is perpendicular to the axis of the air inlet pipe 1. Specifically, a rotating shaft 12 is provided on the air inlet pipe 1, and a bolt 13 is provided at the end of the rotating shaft 12. The buffer plate 11 is threadedly fixed to the rotating shaft 12. Loosening the bolt 13 allows the rotating shaft 12 to rotate around the air inlet pipe 1 to adjust the angle of the buffer plate 11. Tightening the bolt 13 engages with the rotating shaft 12 to tighten the pipe wall of the air inlet pipe 1, thereby fixing the angle of the buffer plate 11. The rotatable arrangement of the buffer plate 11 allows for adjustment of its angle to facilitate cleaning, or adjustment of the channel width and number of bends when gas flows through the air inlet pipe 1, further enhancing the flexibility of the baffle-type gas-liquid separator. In some embodiments, an elastic element can be provided between the rotating shaft 12 and the air inlet pipe 1 to enhance the sealing performance of the air inlet pipe 1.

[0030] More preferably, a demister (not shown in the figure) can be installed inside the baffle 6. The demister further absorbs tiny liquid particles in the gas, improving the dryness and cleanliness of the gas discharged from the housing 2. The demister can be a commercially available wire mesh demister.

[0031] Please refer to Figure 2 and Figure 3 The intake pipe 1 is also equipped with a gate valve housing 3. A sliding gate 31 is slidably disposed within the gate valve housing 3. The sliding direction of the sliding gate 31 is perpendicular to the axis of the intake pipe 1. By moving the position of the sliding gate 31, the sliding gate 31 can block or avoid the intake pipe 1, thereby switching the working state of the intake pipe 1 between open and closed states. Specifically, the sliding gate 31 has a through hole 311. When the through hole 311 is aligned with the intake pipe 1, the intake pipe 1 is in the open working state.

[0032] Preferably, a telescopic assembly 32 is provided on the gate valve housing 3. The movable end of the telescopic assembly 32 is connected to the sliding gate 31. The telescopic assembly 32 can be a cylinder. The telescopic movement of the telescopic assembly 32 drives the sliding gate 31 to move, thereby switching the working state of the air inlet pipe 1 to be open or closed, without the need for manual control, thus improving the automation level of the baffle-type gas-liquid separator.

[0033] The specific workflow of this utility model is as follows: The telescopic assembly 32 extends and retracts to align the through-hole 311 and the inlet pipe 1. Gas containing tiny droplets is injected into the outer casing 2 along the inlet pipe 1. During this process, the buffer plate 11 can be rotated to adjust the width and number of bends in the channel as the gas flows through the inlet pipe 1, thereby changing the gas velocity and flow rate. The gas in the inlet pipe 1 first flows into the gas equalizer 4, and then flows along the mesh 41 on the gas equalizer 4 to the baffle plate 5. The gas flowing out of the inlet pipe 1 passes through the baffle plate 5 along the mesh 41 on the baffle plate 5 and moves upward, gradually accumulating. Finally, it flows along the opening on the baffle 6 to the exhaust port 22 and is discharged from the outer casing 2. During this process, some droplets on the gas adhere to the baffle plate 5, the gas equalizer 4, and the outer casing 2. These droplets flow into the bottom of the outer casing 2 under the action of gravity and are discharged from the outer casing 2 along the drain pipe 21.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
