Description

Technical Field

[0001] This invention relates to the field of gas-liquid-solid separation technology, specifically to a gas-liquid-solid separation device and a turbine vacuum machine. Background Technology

[0002] Turbine vacuum pumps are widely used in vacuum-related processes in industries such as papermaking and alumina. In papermaking, the medium consists of saturated humid air containing liquid water, pulp, and sand. In alumina, the medium consists of saturated humid air containing liquid water and alumina particles. Previously, these processes used water ring vacuum pumps combined with cyclone separators. However, cyclone separators do not provide complete separation, and water ring vacuum pumps, being positive displacement vacuum devices, require a sealing fluid as a pressure chamber, allowing a certain amount of liquid to enter. However, water ring vacuum pumps have low efficiency (only 30%-50%) and low exhaust gas temperature, making them unusable and requiring direct discharge. Both of these methods do not comply with national energy conservation and emission reduction policies. Now, through equipment improvement, centrifugal turbine vacuum pumps are used to replace water ring vacuum pumps. Turbine vacuum pumps have an efficiency of around 80%, and due to the adiabatic compression process, the exhaust gas temperature is high, allowing direct system utilization and avoiding environmental pollution from direct discharge, thus achieving energy conservation and emission reduction goals.

[0003] However, turbine vacuum machines operate at high speeds, typically above 10,000 rpm. A device is needed to achieve efficient gas-liquid-solid separation, ensuring the inlet medium is completely saturated. This prevents cavitation caused by liquid droplets and breakage caused by solid particles in the impeller, the core component of the turbine vacuum machine, thus guaranteeing its safe operation. However, existing cyclone separators have the following shortcomings: First, residual liquid often mixes with the gas phase during the gas-liquid separation process, resulting in suboptimal separation. Second, they cannot separate the liquid and solid components in the mixed medium, leading to concentrated liquid and solid accumulation at the bottom of the tank, increasing cleaning difficulty and the probability of system blockage.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a gas-liquid-solid separation device and a turbine vacuum machine. Summary of the Invention

[0005] The purpose of this invention is to provide a gas-liquid-solid separation device and a turbine vacuum machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas-liquid-solid separation device, comprising a separation tank and a gas-liquid separation component. The bottom of the separation tank is provided with a liquid storage area, and the side of the liquid storage area is connected to a vacuum pump through a liquid outlet. The gas-liquid separation component is fixed to the top of the liquid storage area. The gas-liquid separation component includes a lower partition, an outer sleeve, swirl vanes, a toothed ring, an inner sleeve, and an elbow connector. The lower partition is sealed and fixed to the top of the opening of the liquid storage area, and four outer sleeves are embedded in a ring array on the lower partition. Swirl vanes are built into the top of the outer sleeves, and toothed rings are arranged in a ring array on the outer edge of the swirl vanes. Inner sleeves are embedded inside each of the four outer sleeves, and elbow connectors are connected to the top of the inner sleeves.

[0007] Furthermore, the bottom opening of the outer sleeve is flush with the bottom plane of the lower partition, and the top of the outer sleeve protrudes from the top plane of the lower partition and has a notch facing the outer edge of the lower partition.

[0008] Furthermore, the swirling blades cause the mixed-phase medium entering through the side notch at the top of the outer sleeve to swirl, and the mixed-phase medium moves downward through the gap between the inner and outer sleeves to achieve gas-liquid separation, while the gas is discharged upward through the internal channel of the inner sleeve.

[0009] Furthermore, the separation tank is provided with a linkage impurity removal component in the middle. The linkage impurity removal component includes a spiral air inlet pipe, a spiral plate and a discharge hole. The spiral air inlet pipe is connected to the upper part of the liquid storage area, and a spiral plate is fixed on the inner wall of the spiral air inlet pipe. The end part of the spiral channel formed between two adjacent spiral plates is provided with a discharge hole.

[0010] Furthermore, the linkage impurity removal component also includes an inner recess, a rotating rod, and a driven wheel. The bottom plane of the spiral air inlet pipe has an inner recess that is vertically opposite to the top plane of the liquid storage area. Rotating rods are rotatably installed at both ends of the inner recess. Driven wheels are coaxially connected to the bottom of the rotating rods at both ends, and the driven wheels mesh with the outer edge gear ring of the spiral air inlet pipe for transmission.

[0011] Furthermore, the linkage impurity removal component also includes a belt and a cleaning plate. The top of the rotating rods at both ends is fitted with a belt, and the outer edge of the belt is hinged with a cleaning plate. The cleaning plate is in close contact with the inner wall of the discharge hole on both sides of the concave opening.

[0012] Furthermore, the outer wall of the spiral air inlet pipe is bolted to a solid storage area, and the inlet of the solid storage area is provided with a discharge hole corresponding to the outer side of the concave opening, and the outlet of the solid storage area is connected to a slag outlet.

[0013] Furthermore, the top of the separation tank is provided with a buffer zone, and the bottom of the buffer zone opening is sealed and fixed with an upper partition plate, which is also fixed to the outer wall of the inner sleeve array.

[0014] Furthermore, a secondary filtration assembly is built into the middle of the buffer zone. The secondary filtration assembly includes a cylinder, a connecting flange, an inlet hole, a baffle plate, a guide plate, and a return pipe. The bottom end of the cylinder is fixed to the middle of the upper partition plate, and the top end of the cylinder is connected and fixed to the turbine vacuum machine through the connecting flange. The bottom side of the cylinder has an array of inlet holes that communicate with the elbow pipe at the end of the inner sleeve. Baffle plates are arranged radially inside the cylinder. A guide plate is fixed at the bottom inside the cylinder, and the outer ring cone of the guide plate is set with the inlet hole. The return pipe extends downward from the notch at the top of the guide plate and passes through the upper partition plate and the lower partition plate in sequence to communicate with the liquid storage area.

[0015] A turbine vacuum machine, wherein the turbine vacuum machine is equipped with the aforementioned gas-liquid-solid separation device.

[0016] This invention provides a gas-liquid-solid separation device and a turbine vacuum machine, which have the following beneficial effects;

[0017] 1. In the process of using this invention, firstly, the gas-liquid-solid mixed medium is introduced tangentially through the spiral inlet pipe in the middle of the separator, and a swirling flow is generated between the spiral channels formed by the upper and lower adjacent spiral plates, so that solid impurities are stripped from the mixed medium. On the one hand, this application effectively reduces the risk of system blockage caused by the presence of solid impurities in the mixed medium by prioritizing the stripping and discharge of solid impurities before the gas-liquid separation process. On the other hand, by classifying and collecting solid impurities and liquid media separately, the cleaning difficulty caused by the solid-liquid mixture being collected at the bottom of the tank is reduced. In addition, this application simultaneously performs self-cleaning of the channel required for the discharge of solid impurities while performing gas-liquid separation. This process does not rely on an external prime mover to provide power. By converting the kinetic energy of the mixed medium flowing in into the mechanical energy of the self-cleaning device rotation, a continuous power output is provided for the self-cleaning of the discharge hole, making it more applicable.

[0018] 2. In the process of using this invention, the gas-liquid mixed medium, after being stripped of solid impurities, enters through the side notch of the outer sleeve arranged in the array on the outer edge of the lower partition plate. Under the action of the swirling blades, a swirling flow is generated. As the mixed medium moves downward through the gap between the inner and outer sleeves, the liquid in the mixed medium is thrown outward under the action of centrifugal force and adheres to the inner wall of the outer sleeve, eventually flowing into the liquid storage area. Meanwhile, the gas in the mixed medium gathers inward and is discharged upward through the internal channel of the inner sleeve. This achieves efficient gas-liquid separation. At the same time, the design of the inner and outer double sleeves avoids the possibility of liquid medium splashing into gas medium, which can improve the purity and separation effect of gas medium. This application arranges multiple sets of inner and outer double sleeves in an array on the lower partition plate, so that even if one part is blocked by impurities, the others can still be separated normally, ensuring the overall separation capability of the separator.

[0019] 3. In the process of using this invention, the present application sets a secondary filtration component inside the buffer zone and arranges several baffles radially inside the cylinder. This allows the small amount of liquid mixed in the gas phase medium to be separated by the staggered separation hooks between the baffles and to flow into the liquid storage area through the return pipe vertically connected to the notch at the top of the guide platform. Through the cooperation of the gas-liquid separation component and the secondary filtration component, and through the redundant design of the two filtration processes, the present application further improves the purity and separation effect of the gas phase medium. This ensures that the gas medium entering the turbine vacuum machine from the flange at the top of the cylinder is a completely saturated gas medium, ensuring that the impeller, the core component of the turbine vacuum machine, does not experience cavitation caused by droplets or breakage caused by solid particles, thereby ensuring the safe operation of the turbine vacuum machine.

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] Please see Figures 1 to 6 This invention provides a technical solution: a gas-liquid-solid separation device, including a separation tank 1 and a gas-liquid separation component 4. The bottom of the separation tank 1 is provided with a liquid storage area 2, and the side of the liquid storage area 2 is connected to a vacuum pump through a liquid outlet 3. The gas-liquid separation component 4 is fixed to the top of the liquid storage area 2. The gas-liquid separation component 4 includes a lower partition 401, an outer sleeve 402, swirl vanes 403, a toothed ring 404, an inner sleeve 405, and an elbow connector 406. The lower partition 401 is sealed and fixed to the top of the opening of the liquid storage area 2, and four outer sleeves 402 are embedded in a circular array on the lower partition 401. Swirl vanes 403 are built into the top of the outer sleeves 402, and the swirl vanes 403 are... 03 The outer ring array is provided with a toothed ring 404. The inner sleeve 405 is embedded in the four outer sleeves 402. The top of the inner sleeve 405 is connected to the elbow pipe 406. The bottom opening of the outer sleeve 402 is flush with the bottom plane of the lower partition 401. The top of the outer sleeve 402 protrudes from the top plane of the lower partition 401 and has a notch facing the outer edge of the lower partition 401. The swirl blade 403 causes the mixed medium entering from the side notch at the top of the outer sleeve 402 to swirl. The mixed medium moves downward through the gap between the inner sleeve 405 and the outer sleeve 402 to achieve gas-liquid separation. The gas is discharged upward through the internal channel of the inner sleeve 405.

[0031] The specific operation is as follows: the gas-liquid mixed medium stripped of solid impurities enters through the side notch of the outer sleeve 402 arranged on the outer edge of the lower partition 401, and generates swirling flow under the action of the swirl vanes 403. During the downward movement of the mixed medium through the gap between the inner sleeve 405 and the outer sleeve 402, the liquid in the mixed medium is thrown outward under the action of centrifugal force and adheres to the inner wall of the outer sleeve 402 and finally flows into the liquid storage area 2, while the gas in the mixed medium gathers inward and is discharged upward through the internal channel of the inner sleeve 405. This achieves efficient gas-liquid separation. At the same time, the design of the inner and outer double sleeves avoids the possibility of liquid medium splashing into gas medium, which can improve the purity and separation effect of gas medium. In addition, this application arranges multiple sets of inner and outer double sleeves arranged on the lower partition 401, so that even if one part is blocked by impurities, the others can still be separated normally, ensuring the overall separation capability of the separator.

[0032] Please see Figures 3 to 5The separation tank 1 is equipped with a linkage impurity removal component 5 in the middle. The linkage impurity removal component 5 includes a spiral air inlet pipe 501, a spiral plate 502, and a discharge hole 503. The spiral air inlet pipe 501 is connected to the upper part of the liquid storage area 2, and the spiral plate 502 is fixed on the inner wall of the spiral air inlet pipe 501. The end part of the spiral channel formed between two adjacent spiral plates 502 is provided with a discharge hole 503. The linkage impurity removal component 5 also includes an inner recess 504, a rotating rod 505, and a driven wheel 506. The bottom plane of the spiral air inlet pipe 501 has an inner recess 504 that is vertically opposite to the top plane of the liquid storage area 2, and the rotating rod is rotatably installed at both ends of the inner recess 504. 505, the bottom of the two end rotating rods 505 are coaxially connected to the driven wheel 506, and the driven wheel 506 meshes with the outer edge gear ring 404 of the spiral air inlet pipe 501 for transmission. The linkage impurity removal component 5 also includes a belt 507 and a cleaning plate 508. The top of the two end rotating rods 505 is fitted with a belt 507, and the outer edge of the belt 507 is hinged with a cleaning plate 508. The cleaning plate 508 is tightly fitted with the inner wall of the discharge holes 503 on both sides of the concave opening 504. The outer wall of the spiral air inlet pipe 501 is bolted to a solid storage area 6, and the inlet of the solid storage area 6 is set to correspond to the outer side discharge hole 503 of the concave opening 504. The outlet of the solid storage area 6 is connected to a slag outlet 7.

[0033] The specific operation is as follows: the gas-liquid-solid mixed medium is introduced tangentially through the spiral inlet pipe 501 in the middle of the separator 1, and a swirling flow is generated between the spiral channels formed by the upper and lower adjacent spiral plates 502. This causes solid impurities to be stripped from the mixed medium and enter through the inner side of the discharge hole 503 at the end of the spiral channel, and then exit through the discharge hole 503 on the outer side of the concave opening 504 and fall into the solid storage area 6. This application, on the one hand, effectively reduces the risk of system blockage caused by the presence of solid impurities in the mixed medium by prioritizing the stripping and discharge of solid impurities before the gas-liquid separation process; on the other hand, by classifying and collecting solid impurities and liquid media separately, it reduces the cleaning difficulty caused by the solid-liquid mixture being collected at the bottom of the tank. Furthermore, when the swirling blades... During the process of 403 rotating and generating swirling flow under the impetus of the gas-liquid mixed medium, the swirling blades 403 are driven by the meshing of the outer edge toothed ring 404 and the driven wheel 506 at the bottom of the rotating rod 505, thereby driving the belt 507 sleeved on the top of the rotating rod 505 to rotate. This causes the cleaning plate 508 hinged to the outside of the belt 507 to adhere to the discharge holes 503 on both sides of the concave opening 504 for scraping and cleaning. This allows the present application to simultaneously perform self-cleaning of the channel required for the discharge of solid impurities while performing gas-liquid separation. This process does not rely on an external prime mover to provide power. By converting the kinetic energy of the mixed medium flowing in into the mechanical energy of the self-cleaning device rotation, a continuous power output is provided for the self-cleaning of the discharge hole 503, making it more applicable.

[0034] Please see Figures 7 to 8The top of the separator 1 is equipped with a buffer zone 8, and the bottom of the opening of the buffer zone 8 is sealed and fixed with an upper baffle 9. The upper baffle 9 is fixed to the outer wall of the inner sleeve 405. A secondary filter assembly 10 is built into the middle of the buffer zone 8. The secondary filter assembly 10 includes a cylinder 1001, a connecting flange 1002, an inlet hole 1003, a baffle 1004, a guide platform 1005, and a return pipe 1006. The bottom of the cylinder 1001 is fixed to the middle of the upper baffle 9, and the top of the cylinder 1001 is connected to the turbine vacuum through the connecting flange 1002. The empty machine is connected and fixed. The bottom side of the cylinder 1001 is provided with an inlet hole 1003 that communicates with the elbow pipe 406 at the end of the inner sleeve 405. The cylinder 1001 is radially arranged with baffles 1004. The bottom of the cylinder 1001 is fixed with a guide platform 1005. The outer ring cone of the guide platform 1005 is provided with the inlet hole 1003. The top notch of the guide platform 1005 extends downward with a return pipe 1006. The return pipe 1006 passes through the upper partition 9 and the lower partition 401 in sequence and communicates with the liquid storage area 2.

[0035] The specific operation is as follows: There may still be some liquid residue in the gas phase medium that is introduced into the top buffer zone 8 of the separator tank 1 from bottom to top through the inner sleeve 405. Therefore, this application sets a secondary filter component 10 inside the buffer zone 8 and arranges several baffles 1004 radially inside the cylinder 1001 so that a small amount of liquid mixed in the gas phase medium will be separated by the staggered separation hooks between the baffles 1004 and flow into the liquid storage area 2 through the return pipe 1006 vertically connected to the notch at the top of the guide platform 1005.

[0036] A turbine vacuum machine is provided, which is equipped with the gas-liquid-solid separation device described above. Through the redundant design of two filtration processes, the purity and separation effect of the gaseous medium are further improved, so that the gas medium entering the turbine vacuum machine from the top connecting flange 1002 of the cylinder 1001 is a completely saturated gas medium. This ensures that the impeller, the core component of the turbine vacuum machine, does not experience cavitation caused by liquid droplets or breakage caused by solid particles, thereby ensuring the safe operation of the turbine vacuum machine.

[0037] In summary, when using this gas-liquid-solid separation device and turbine vacuum machine, firstly, the gas-liquid-solid mixed medium is introduced tangentially through the spiral inlet pipe 501 in the middle of the separation tank 1, and a swirling flow is generated between the spiral channels formed by the upper and lower adjacent spiral plates 502. This causes solid impurities to be stripped from the mixed medium and enter through the inside of the discharge hole 503 at the end of the spiral channel, and then exit through the discharge hole 503 on the outside of the concave opening 504 before falling into the solid storage area 6. This application, on the one hand, effectively reduces the risk of system blockage caused by the presence of solid impurities in the mixed medium by prioritizing the stripping and discharge of solid impurities before the gas-liquid separation process; on the other hand, by classifying and collecting solid impurities and liquid media separately, it reduces the cleaning difficulty caused by the solid-liquid mixture being collected at the bottom of the tank. The gas-liquid mixed medium, stripped of solid impurities, enters through the side notch of the outer sleeve 402 arrayed on the outer edge of the lower partition 401. Under the action of the swirl vanes 403, it generates swirling flow. As the mixed medium moves downwards through the gap between the inner sleeve 405 and the outer sleeve 402, the liquid in the mixed medium is thrown outwards by centrifugal force and adheres to the inner wall of the outer sleeve 402, eventually flowing into the liquid storage area 2. Meanwhile, the gas in the mixed medium gathers inwards and is discharged upwards through the internal channel of the inner sleeve 405. This achieves efficient gas-liquid separation. Furthermore, the double-sleeve design avoids the possibility of liquid medium splashing into the gas medium, improving the purity and separation effect of the gas medium. In addition, this application arrays multiple sets of fitted... The double-walled design ensures that even if one section is blocked by impurities, the others can still separate normally, guaranteeing the overall separation capacity of the separator. Furthermore, as the swirling blades 403 rotate under the influence of the gas-liquid mixed-phase medium, generating a swirling flow, the blades 403 are driven by the meshing of the outer toothed ring 404 with the driven wheel 506 at the bottom of the rotating rod 505. This drives the belt 507 mounted on the top of the rotating rod 505 to rotate, causing the cleaning plates 508 hinged to the outside of the belt 507 to scrape and clean the discharge holes 503 on both sides of the concave opening 504. This allows the separator to simultaneously self-clean the channels for discharging solid impurities while performing gas-liquid separation. This process does not rely on an external prime mover; it utilizes the kinetic energy of the mixed-phase medium flowing in. The mechanical energy converted into the rotation of the self-cleaning device provides a continuous power output for the self-cleaning of the discharge port 503, making it more versatile. Finally, some liquid residue may still remain in the gaseous medium that flows from the bottom to the top buffer zone 8 of the separator 1 through the inner sleeve 405. Therefore, this application sets a secondary filtration component 10 inside the buffer zone 8 and arranges several baffles 1004 radially inside the cylinder 1001. This allows the small amount of liquid mixed in the gaseous medium to be separated by the staggered separation hooks between the baffles 1004, and then flows into the liquid storage area 2 through the return pipe 1006 vertically connected to the notch at the top of the guide platform 1005. This application achieves this by cooperating the gas-liquid separation component 4 and the secondary filtration component 10, through the redundant design of two filtration processes.To further improve the purity and separation effect of the gaseous medium, the gas medium entering the turbine vacuum machine through the top connecting flange 1002 of the cylinder 1001 is ensured to be a completely saturated gas medium. This guarantees that the impeller, the core component of the turbine vacuum machine, will not experience cavitation caused by droplets or breakage caused by solid particles, thereby ensuring the safe operation of the turbine vacuum machine.
