Technical Field
[0001] This utility model relates to the field of separation device technology, and more specifically, to a multi-stage gas-liquid separation device. Background Technology
[0002] In chemical production processes, gas-liquid separation devices are used to separate gas-liquid mixtures, allowing the gas and liquid components to proceed independently to the next production stage. Existing gas-liquid separation devices for large-scale chemical operations often employ centrifugal separation or extended pipeline separation methods. These methods have low production efficiency, require significant investment in design and installation, and consume high levels of electricity. Furthermore, after prolonged use, these devices may loosen, malfunction, and wear, necessitating regular inspection and maintenance, resulting in high operating costs and hindering continuous production. Therefore, a multi-stage gas-liquid separation device is proposed. Summary of the Invention
[0003] (a) Technical problems to be solved To address at least one of the aforementioned problems, this invention first provides a multi-stage gas-liquid separation device, which separates gas and liquid through multiple stages, thereby improving material separation efficiency and enhancing the practicality of the separation device.
[0004] (II) Technical Solution To solve the aforementioned technical problem, this utility model provides a multi-stage gas-liquid separation device, including a separation tank, a first mounting frame, and a second mounting frame. The first mounting frame is fixedly installed at the upper end of the separation tank, and the second mounting frame is fixedly installed at the lower end of the separation tank. The second mounting frame is provided with a liquid collection tank, and a second leakage tank is provided at the center of the bottom of the liquid collection tank. A central frame is provided on the liquid collection tank and a vertical rod is provided on the central frame. A second separation frame is provided on the vertical rod near one end of the liquid collection tank, and a first separation frame is provided above the second separation frame. The top of the vertical rod is fixedly inserted into the first mounting frame, and a metal wire mesh is provided on the first mounting frame. An external support tank is provided at the outer end of the separation tank, and a gas outlet pipe is provided at the top of the external support tank. A gas outlet pipe is provided inside the gas outlet pipe. When the material enters the separation tank, it falls onto the second separation frame and then flows into the liquid collection tank. The gas flow automatically separates from the liquid. The liquid it carries is captured and condensed by the first separation frame, the first mounting frame, and the metal wire mesh, and then drips into the liquid collection tank. The separated gas is discharged through the gas outlet pipe.
[0005] Furthermore, the first separation frame includes a first spiral blade, a second spiral blade, and a third spiral blade with equal spacing. The first spiral blade, the second spiral blade, and the third spiral blade are each provided with multiple sets of through grooves. The first spiral blade, the second spiral blade, and the third spiral blade are all fixedly connected to the upright.
[0006] Furthermore, the second separation frame has the same three sets of spiral blades as the first separation frame, but the three sets of spiral blades of the second separation frame do not have through slots.
[0007] Furthermore, the upright has an installation slot above the first separation frame, and a material transfer tray is provided on the installation slot. The bottom edge of the material transfer tray has a first leakage groove.
[0008] Furthermore, the external support tank is provided with a set of liquid inlet racks in the middle section, and a feed pipe is provided in the liquid inlet racks. The feed pipe extends through the separation tank and above the material transfer tray.
[0009] Furthermore, the central frame is configured as a cross structure, and the central frame is attached to the second leakage tank.
[0010] Furthermore, the bottom of the liquid collection tank is provided with a liquid collection funnel at the outer end of the second leakage tank, and the bottom of the liquid collection funnel is provided with a liquid guide pipe, which extends out of the external support tank and connects to the liquid outlet valve.
[0011] Furthermore, the bottom of the liquid collection tank is provided with a vibration connection cover, which is connected to the vibration generator.
[0012] Furthermore, a coolant coil is provided at the upper end of the gap between the external support tank and the separation tank.
[0013] (III) Beneficial Effects This utility model provides a multi-stage gas-liquid separation device. It uses a second separation frame to increase the material flow area and duration. Combined with the material's own gravity and low-frequency vibration, it can quickly separate the gas in the material. During the gas rise, the very small amount of liquid carried by the gas passes through the first separation frame for first-stage capture, then through the first mounting frame for second-stage capture, and finally through the metal wire mesh for third-stage capture. This allows the liquid carried by the gas to condense and drip down, preventing the gas from carrying liquid out and affecting the use of the next process. This device only uses a vibration generator to emit low-frequency vibration to cooperate with gas-liquid separation. Its energy consumption is low, which can effectively save electricity resources.

Detailed Implementation
[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0017] See Figures 1 to 5This utility model provides a multi-stage gas-liquid separation device, including a separation tank 6, a first mounting frame 8, and a second mounting frame 15. The first mounting frame 8 is fixedly installed on the upper end of the separation tank 6, and the second mounting frame 15 is fixedly installed on the lower end of the separation tank 6. The second mounting frame 15 is provided with a liquid collection tank 16, and a second leakage tank is provided at the center of the bottom of the liquid collection tank 16. A central frame 17 is provided on the liquid collection tank 16 and the central frame 17 is provided with a vertical rod 10. A second separation frame 13 is provided on the vertical rod 10 near the end of the liquid collection tank 16. A first separation frame 11 is provided above the second separation frame 13. The top of the vertical rod 10 is fixedly inserted into the first mounting frame 8. A metal wire mesh 9 is provided on the first mounting frame 8. An external support tank 1 is provided at the outer end of the separation tank 6. An air outlet pipe 2 is provided at the top of the external support tank 1, and an air outlet pipe is provided inside the air outlet pipe 2. After the material enters the separation tank 6, it falls onto the second separation frame 13 and flows into the liquid collection tank. Inside the tank 16, the airflow automatically separates from the liquid. The liquid it carries is captured and condensed by the first separating frame 11, the first mounting frame 8, and the metal wire mesh 9, and then drips into the collection tank 16. The separated gas is discharged through the gas outlet pipe. This scheme utilizes the influence of gravity to make the gas-liquid mixture fall onto the second separating frame 13. The material is guided by the spiral blades of the second separating frame 13 and falls into the collection tank 16 through the gap between the spiral blades and the separating tank 6. During the falling and flowing of the material, the gas will quickly separate from the liquid. The gas will carry a very small amount of liquid to the upper part of the inner cavity of the separating tank 6. This part of the gas first passes through the gap and through the groove of the first separating frame 11. The structure of the first separating frame 11 forms a first-stage capture structure, which facilitates liquid condensation. Then the gas flows through the first mounting frame 8 and the metal wire mesh 9, where the first mounting frame 8 and the metal wire mesh 9 perform the second and third-stage capture, improving the gas-liquid separation efficiency and effect.
[0018] The first mounting frame 8 includes an annular frame fixedly mounted to the separation tank 6 and a grid-shaped mounting plate disposed within the annular frame. A metal wire mesh 9 is disposed on the grid-shaped mounting plate. Gas enters the space where the metal wire mesh 9 is installed through the slots in the grid-shaped mounting plate. The metal wire mesh 9 is a mesh structure woven from metal wires rolled into a cylinder and placed on the first mounting frame 8. The continuous and uniformly distributed structure of the metal wire mesh 9 can form a high-density third-stage capture structure for the gas, which is convenient for intercepting liquid.
[0019] The bottom of the external support tank 1 is equipped with a fixed bracket 4, which facilitates the quick and easy installation of the separation device at the designated working position.
[0020] See Figure 4 and Figure 5The first separating frame 11 includes a first spiral blade 111, a second spiral blade 112, and a third spiral blade 113 with equal spacing. Each of the three spiral blades has multiple sets of through slots. All three spiral blades are fixedly connected to the upright 10. The three sets of spiral blades are arranged in a spiral shape that gradually unfolds from the inside out. When the three sets of spiral blades are fixedly installed to the upright 10 at equal intervals, the first separating frame... The outermost edges of the three sets of spiral blades of the first separation frame 11 are all in contact with the inner wall of the separation tank 6. That is, the inner wall of the separation tank 6, together with the upright rod 10, establishes the installation and fixation of the three sets of spiral blades of the first separation frame 11. The gas separated by the guide flows through the gap between the three sets of spiral blades and through each set of through slots. The metal structure of these three sets of spiral blades, except for the through slots, can capture the liquid in the gas in the first stage. The liquid condenses on the blades and falls onto the second separation frame 13, and falls into the liquid collection tank 16 through the gap of the second separation frame 13.
[0021] The second separating frame 13 is equipped with three sets of spiral blades identical to those of the first separating frame 11. The three sets of spiral blades of the second separating frame 13 do not have through grooves, which facilitates the material to fall downward along the blade contour. The three sets of spiral blades of the second separating frame 13 are installed in a downward extending mode, which facilitates the material falling from the material transfer tray 12 to fall completely from the top center of the three sets of spiral blades of the second separating frame 13 in the direction of blade extension. During this period, the material can separate the mixed gas due to the influence of gravity and the extension of the flow. The gas runs upward and, together with the separation device above the second separating frame 13, further separates the carried liquid.
[0022] The upright 10 is provided with an installation slot 101 above the first separation frame 11. A material transfer tray 12 is provided on the installation slot 101. A first leakage groove is provided on the bottom edge of the material transfer tray 12. The upright 10 is installed in a limiting position with the material transfer tray 12 through the installation slot 101. When the material transfer tray 12 is in the installation state, the bottom of its tray body abuts against the top edge of the second separation frame 13, which facilitates the second separation frame 13 to cooperate with the upright 10 to achieve stable setting of the material transfer tray 12. The feed pipe 14 guides the material to the material transfer tray 12. Under normal circumstances, the continuously output material falls from the first leakage groove of the material transfer tray 12 onto the second separation frame 13. The gas is separated from the material by the gravity of the falling material and the guiding extension of the spiral blades.
[0023] See Figure 1 and Figure 2An inlet rack 3 is provided in the middle section of the external support tank 1. The inlet rack 3 is provided with a feed pipe 14. The feed pipe 14 extends through the separation tank 6 to the top of the material transfer plate 12. The inlet rack 3 supports the feed pipe 14. The feed pipe 14 is provided with a feed valve. The feed pipe 14 conveys the material to the material transfer plate 12 for output. The material transfer plate 12 concentrates the material and can evenly guide it to the second separation rack 13. The multiple sets of spiral blades on the second separation rack 13 can evenly guide and separate the gas and liquid of the material.
[0024] The central frame 17 is designed as a cross structure and is attached to the second leakage tank. In this design, the first separation frame 11 and the second separation frame 13 are fixedly connected to the separation tank 6 via the upright 10. The first separation frame 11 and the second separation frame 13 do not have relative displacement with the separation tank 6 and the upright 10. The central frame 17 is set on the collection tank 16 to enhance the installation stability of the upright 10. The central frame 17, in conjunction with the first mounting frame 8, fixes the upright 10 to ensure the stable use of the first separation frame 11 and the second separation frame 13. The central frame 17 is a cross structure, which can form a communication space between the second leakage tank and the collection tank 16 outside the structure of the central frame 17, making it easy for the accumulated liquid to fall from the second leakage tank.
[0025] See Figure 3 The bottom of the collection tank 16 is provided with a collection funnel 18 at the outer end of the second leakage tank. The bottom of the collection funnel 18 is provided with a guide pipe 19, which extends out of the external support tank 1 and connects to the outlet valve 5. The inner cavity of the collection funnel 18 is provided with a lifting plug 22 at the bottom of the second leakage tank. The bottom of the lifting plug 22 is provided with a lifting rod 23, and the bottom of the lifting rod 23 is provided with a sealing electric cylinder 24. The top of the lifting plug 22 is provided with a pressure level gauge. When the pressure level gauge detects that the liquid in the collection tank 16 has reached a certain amount, the feed pipe 14 stops feeding, and the sealing electric cylinder 24 controls the lifting rod 23 to move down, thereby disconnecting the connection between the lifting plug 22 and the second leakage tank, so that the liquid can flow from the collection funnel 18 into the guide pipe 19. The outlet valve 5 controls the output of the liquid. When the pressure level gauge does not detect any pressure, that is, the liquid is completely drained, the lifting plug 22 returns to its original position, and the separation device can resume separation operation.
[0026] The bottom of the liquid collection tank 16 is provided with a vibration connection cover 20, which is connected to the vibration generator 21. The vibration connection cover 20 will output the vibration generated by the vibration generator 21 to the liquid collection tank 16. The liquid collection tank 16 serves as the bottom component of the separation tank 6, meaning that the entire separation tank 6 will generate vibrations at a moving frequency amplitude, which facilitates the expulsion of gas from the liquid in the liquid collection tank 16. At the same time, it can drive the first separation frame 11, the second separation frame 13, the first mounting frame 8, the metal wire mesh 9, and the condensed water droplets on the inner wall of the separation tank 6 to fall and complete the collection, thereby improving the gas-liquid separation speed of the material.
[0027] See Figure 2 A coolant coil 7 is provided at the upper end of the gap between the external support tank 1 and the separation tank 6. The coolant coil 7 has an inlet and an outlet on the external support tank 1. If the material temperature is higher than the ambient temperature when it is input into the separation tank 6, the hot gas will move quickly to the top of the separation tank 6. The coolant flowing in the coolant coil 7 can reduce the temperature of the space at the top of the separation tank 6, reduce the gas flow speed, and accelerate the liquid condensation speed, which makes it easier to adjust the gas-liquid separation process.
[0028] This utility model provides a multi-stage gas-liquid separation device. The material is conveyed to a material transfer tray 12 via a feed pipe 14. The material transfer tray 12 evenly distributes the material onto a second separation frame 13, where spiral blades guide and separate the gas. The liquid then settles into a collection tank 16 for temporary storage, while the gas carries some liquid upwards. During this process, the gas flows out through the grooves and gaps on multiple sets of spiral blades of the first separation frame 11, where the blade structure performs a first-stage capture of the liquid. When the gas rises to the first mounting frame 8, it undergoes a second-stage capture via a grid-like plate on the first mounting frame 8. A third stage capture is then performed by a large number of evenly distributed metal wires on a wire mesh 9. This process maximizes the removal of liquid carried in the gas, achieving precise control of the gas-liquid separation. The gas is then discharged from the outlet pipe, and once a certain amount of liquid has accumulated, it is discharged through a liquid outlet valve 5. All structures in this design are coated with an anti-corrosion coating, effectively extending the device's service life.
[0029] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
