Description

Technical Field

[0001] This utility model relates to the technical field of gas-liquid separation devices, and in particular to a gas-liquid separation device. Background Technology

[0002] The production of sodium dichloroquinoline involves multiple chemical reactions and process steps. Some reactions may generate gases, while liquid materials are also present in the reaction system. For example, in some organic synthesis reactions, side reactions may produce gases, or during the separation and purification of reaction products, it is necessary to convert some volatile substances into a gaseous state through heating or depressurization. In these cases, a gas-liquid separation device becomes particularly important. It can effectively separate the generated gas from the liquid, facilitating further gas treatment (such as tail gas treatment), while also ensuring the purity and quality of the liquid product or intermediate product, improving production efficiency and safety, and reducing the introduction of impurities and potential safety hazards. Existing gas-liquid separation devices allow the gas-liquid mixture to directly enter the tank, resulting in a short movement path, short separation time, and incomplete separation. Utility Model Content

[0003] The purpose of this invention is to provide a gas-liquid separation device that solves the problem that existing gas-liquid separation devices, when in use, allow the gas-liquid mixture to directly enter the tank, resulting in a short movement path, short separation time, and incomplete separation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a gas-liquid separation device, including a gas-liquid separation tank. Support legs are provided at the bottom of the gas-liquid separation tank. An inlet connecting pipe is provided on the side wall of the gas-liquid separation tank. An outlet connecting pipe is provided at the bottom of the gas-liquid separation tank.

Mounting holes are provided on the partition, and mounting frames are provided within the mounting holes. Several rotatable air guide plates are provided within the mounting frames.

[0006] Furthermore, the flow control mechanism includes a support column, which is disposed inside the gas-liquid separator via a connecting frame, and a plurality of inclined flow channel assemblies are disposed on the outer side of the support column in sequence.

[0007] Furthermore, the inclined flow channel assembly includes an inlet pipe and an outlet pipe, which are respectively disposed on both sides of the support column. A liquid flow channel is provided on the outside of the inlet pipe, the support column, and the outlet pipe. One end of the liquid flow channel is connected to the inlet of the inlet pipe, and the other end of the liquid flow channel passes through the inlet pipe, the support column, and the outlet pipe in sequence and then connects to the outlet of the outlet pipe.

[0008] Furthermore, the inlet pipe in the uppermost inclined flow channel assembly is connected to the inlet connection pipe, and the outlet pipe in the inclined flow channel assembly is connected to the inlet pipe in the next inclined flow channel assembly.

Detailed Implementation

[0024] like Figure 1-6 As shown, a gas-liquid separation device includes a gas-liquid separation tank 1. Three support legs 2 are connected to the bottom of the gas-liquid separation tank 1 to ensure its stable placement on the ground. An inlet connecting pipe 3 is connected to the side wall of the gas-liquid separation tank 1, and an outlet connecting pipe 4 is connected to the bottom of the gas-liquid separation tank 1. A valve is installed on the outlet connecting pipe 4. A top cover 5 is detachably installed on the top of the gas-liquid separation tank 1 by bolts. The connection between the top cover 5 and the gas-liquid separation tank 1 is sealed by a sealing assembly. The sealing assembly adopts a common type of tank body used in the prior art. The sealing component is sufficient, and its specific structure will not be described in detail here. The top cover 5 is connected to the air outlet pipe 6, and a valve is installed on the air outlet pipe 6. The air outlet pipe 6 is connected to the air suction pump 7. A flow-slowing mechanism is installed inside the gas-liquid separator 1 at a height lower than the inlet connecting pipe 3. A partition plate 13 is connected inside the gas-liquid separator 1 and above the flow-slowing mechanism. A rectangular mounting hole is opened on the partition plate 13, and a mounting frame 14 is connected in the mounting hole. Several rotatable air guide plates 15 are installed in the mounting frame 14.

[0025] like Figure 2As shown, the slow-flow mechanism includes a support column 8, which is connected to the inner wall of the gas-liquid separator 1 through multiple connecting frames 12, so that the support column 8 is located on the vertical axis of the gas-liquid separator 1. Three inclined flow channel assemblies connected in sequence are provided on the outer side of the support column 8.

[0026] Specifically, such as Figure 3 As shown, the inclined flow channel assembly includes an inlet pipe 9 and an outlet pipe 11. The inlet pipe 9 and the outlet pipe 11 are respectively disposed on both sides of the support column 8. A liquid flow channel 10 is connected to the outside of the inlet pipe 9, the support column 8 and the outlet pipe 11. One end of the liquid flow channel 10 is connected to the inlet port 9-1 of the inlet pipe 9, and the other end of the liquid flow channel 10 passes through the inlet pipe 9, the support column 8 and the outlet pipe 11 in sequence and is connected to the outlet port 11-1 of the outlet pipe 11. The height of the liquid flow channel 10 gradually decreases.

[0027] The inlet pipe 9 in the uppermost inclined flow channel assembly is connected to the inlet connecting pipe 3, and the outlet pipe 11 in the inclined flow channel assembly is connected to the inlet pipe 9 in the next inclined flow channel assembly.

[0028] pass Figure 1 It can be seen that the diameter of the end of the inlet connecting pipe 3 located outside the gas-liquid separator 1 is smaller, through... Figure 2 It can be seen that the diameter of the end of the inlet connecting pipe 3 inside the gas-liquid separator 1 increases. Utilizing the density difference between gas and liquid, after the gas-liquid mixture enters, the flow velocity decreases rapidly due to the sudden increase in the flow cross-sectional area. This causes the liquid to flow downwards along the liquid flow channel 10, while the gas flows upwards. Since the distance between the sequentially connected liquid flow channels 10 is relatively long, the liquid takes a longer time to move from the inlet connecting pipe 3 to the bottom of the gas-liquid separator 1, allowing the gas to be fully separated from the liquid. The gas is then pumped away by the suction pump 7, which facilitates the discharge of the gas.

[0029] like Figure 4-6 As shown, several air guide plates 15 rotate synchronously under the drive of a linkage mechanism. The middle part of the air guide plate 15 is rotatably connected to the mounting frame 14 through a rotating shaft. The linkage mechanism is installed on the upper part of several air guide plates 15. The linkage mechanism includes a linkage rod 16, which is connected to the upper part of several air guide plates 15 respectively. An mounting plate 22 is connected to the outside of the gas-liquid separator 1. A mounting seat 23 is connected to the mounting plate 22. An operating element 18 is hinged to the mounting seat 23. A limiting sleeve 21 is installed on the outer wall of the gas-liquid separator 1. The linkage rod 16 passes through the limiting sleeve 21 and is connected to the operating element 18 through a connecting rod 17.

[0030] In use, the linkage rod 16 is pulled to the left by the operating component 18. The linkage rod 16 drives the air guide plate 15 to rotate counterclockwise. The angle of the air guide plate 15 is adjusted, and the gas moves upward through the exhaust channel between the two air guide plates 15. The size of the exhaust channel is changed by adjusting the angle of the air guide plate 15, thereby changing the speed of gas discharge. After adjustment, a positioning rod can be inserted into the through hole on the exposed end of the linkage rod 16. The bottom end of the positioning rod is inserted into the mounting hole on the mounting plate 22 for positioning.

[0031] The bottom surface of the mounting frame 14 is connected to a limiting frame 19 with a bent edge at a corresponding position of each air guide plate 15. When the air guide plate 15 is tilted to the maximum angle, the air guide plate 15 contacts the bent edge of the limiting frame 19. A limiting plate 20 is connected to the bottom surface of the air guide plate 15 and located below the mounting frame 14. When the air guide plate 15 is rotated to a horizontal position, the limiting plate 20 blocks the gap between the two air guide plates 15.

[0032] The working process of this utility model is as follows:

[0033] First, the gas-liquid mixture enters the gas-liquid separator 1 through the inlet connecting pipe 3. Due to the sudden increase in the flow cross-sectional area, the flow velocity decreases rapidly, causing the liquid to flow downward along the liquid flow channel 10 and the gas to flow upward. Since the distance between the sequentially connected liquid flow channels 10 is relatively long, the liquid takes a long time to move from the inlet connecting pipe 3 to the bottom of the gas-liquid separator 1, allowing the gas to be fully separated from the liquid. Then, the gas is drawn away by the suction pump 7 to perform gas-liquid separation.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
