Description

Technical Field

[0001] The invention relates to the technical field of gas-liquid-solid separation, in particular to a gas-liquid-solid separation device and a turbine vacuum machine. Background Art

[0002] Turbine vacuum machines are widely used in vacuum-related processes in the papermaking, alumina and other industries. For the papermaking industry, the medium components in this process are saturated wet air containing liquid water, pulp, sand, etc. For the alumina industry, the medium components in this process are saturated wet air containing liquid water, alumina particles, etc. Previously, this type of process used a water ring vacuum pump + a cyclone gas-liquid separator. Since the cyclone gas-liquid separator does not separate thoroughly, and the water ring vacuum pump is a volumetric vacuum equipment, it requires a sealing liquid as a pressure cavity, which allows a certain amount of liquid to enter, but the efficiency of the water ring vacuum pump is low, only 30%-50%, and the exhaust gas temperature is low, so it cannot be directly used and needs to be discharged directly. These two are not in line with the national energy conservation and emission reduction policy. Now through equipment improvement, a centrifugal turbine vacuum machine is used to replace the water ring vacuum pump. The efficiency of the turbine vacuum machine is about 80%. Because it is an adiabatic compression process, the exhaust gas temperature is high and can be directly used by the system to avoid direct discharge and cause environmental pollution, so as to achieve the purpose of energy conservation and emission reduction.

[0003] However, the rotation speed of the turbine vacuum machine is relatively high, generally above 10,000 revolutions, and a device is required to achieve efficient separation of gas, liquid and solid, so that the intake medium of the turbine vacuum machine is completely saturated gas medium, and to ensure that the core component of the turbine vacuum machine, the impeller, does not experience cavitation caused by droplets and fracture caused by solid particles, in order to ensure the safe operation of the turbine vacuum machine. However, the existing cyclone separators have the following deficiencies when used. First, residual liquid medium is often mixed into the gas medium in the gas-liquid separation process, resulting in unsatisfactory gas-liquid separation effect. Secondly, it is impossible to screen the liquid and solid in the mixed medium, resulting in concentrated collection of liquid and solid at the bottom of the tank, which increases the difficulty of cleaning and the probability of system blockage.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a gas-liquid-solid separation device and a turbine vacuum machine are proposed. Summary of the invention

[0010] Furthermore, the linkage impurity removal component also includes an inner recess, a rotating rod and a driven wheel.

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

[0017] 1. During the use of the present invention, first, the gas-liquid-solid mixed medium is introduced tangentially from the spiral air inlet pipe in the middle of the separation tank, and a swirl 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, the present application preferentially realizes the stripping and discharge of solid impurities before the gas-liquid separation process, effectively reducing the risk of system blockage caused by the presence of solid impurities in the mixed medium. On the other hand, the solid impurities and liquid medium are classified and collected, thereby reducing the difficulty of cleaning caused by the collection of solid-liquid mixture at the bottom of the tank. In addition, the present application performs self-cleaning of the channel required for the discharge of solid impurities while performing the gas-liquid separation operation. This process does not rely on an external prime mover to provide power. By converting the kinetic energy of the mixed medium when it flows in into the mechanical energy of the rotation of the self-cleaning device, a continuous power output is provided for the self-cleaning of the discharge hole, and the applicability is stronger.

[0018] 2. During the use of the present invention, secondly, the gas-liquid mixed medium stripped of solid impurities enters through the side notch of the outer sleeve arranged in an array on the outer edge of the lower partition, and generates a swirl under the action of the swirl blades. During the downward movement of the mixed medium through the gap between the inner sleeve and the outer sleeve, 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 and finally flows into the liquid storage area, while the gas in the mixed medium is gathered inward and discharged upward from the internal channel of the inner sleeve, achieving efficient gas-liquid separation. At the same time, the possibility of liquid medium splashing into gas medium is avoided through the design of inner and outer double sleeves, which can improve the purity and separation effect of gas medium. The present application arranges multiple sets of inner and outer double sleeves in an array on the lower partition, so that even if one of them is blocked by impurities, the others can still be separated normally, thereby ensuring the overall separation capacity of the separator;

[0019] 3. During the use of the present invention, finally, the present application sets a secondary filtration component inside the buffer zone, and arranges several baffles radially inside the cylinder, so that a small amount of liquid mixed in the gas phase medium will be separated by the separation hooks staggered between the baffles, and merged into the liquid storage area through the return pipe vertically connected to the notch at the top of the guide table. The present application further improves the purity and separation effect of the gas phase medium through the coordination of the gas-liquid separation component and the secondary filtration component, and through the redundant design of the two filtration processes, so that the intake medium entering the turbine vacuum machine from the top connecting flange of the cylinder is completely saturated gas medium, ensuring that the core component of the turbine vacuum machine, the impeller, does not suffer from cavitation caused by droplets and fracture caused by solid particles, thereby ensuring the safe operation of the turbine vacuum machine.

[0033] The specific operation is as follows: the gas-liquid-solid mixed phase medium is introduced tangentially from the spiral air inlet pipe 501 in the middle of the separation tank 1, and a swirl flow is generated between the spiral channels formed by the upper and lower adjacent spiral plates 502, so that the solid impurities are stripped from the mixed phase medium, and enter from the inner side of the discharge hole 503 at the end of the spiral channel, and then fall into the solid storage area 6 after passing through the discharge hole 503 on the outer side of the inner recess 504. On the one hand, the present application effectively reduces the risk of system blockage due to the presence of solid impurities in the mixed phase medium by preferentially realizing the stripping and discharge of solid impurities before the gas-liquid separation process. On the other hand, the solid impurities and liquid medium are classified and collected to reduce the cleaning difficulty caused by the solid-liquid mixture collected at the bottom of the tank. Furthermore, when the swirl blades In the process of self-rotation and swirl flow generated by the gas-liquid mixed medium, the swirl blade 403 is driven by the meshing transmission of the outer edge gear 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, so that the cleaning sheet 508 hinged on the outside of the belt 507 is attached to the discharge holes 503 on both sides of the inner recess 504 for scraping and cleaning, so that the present application can simultaneously self-clean the channels required for the discharge of solid impurities while performing the gas-liquid separation operation.

The empty machine is connected and fixed, and an array of access holes 1003 are provided on the side surface of the bottom end of the cylinder 1001, which are connected to the elbow pipe 406 at the end of the inner sleeve 405, and baffles 1004 are arranged radially inside the cylinder 1001.

[0037] In summary, when using the gas-liquid-solid separation device and the turbine vacuum machine, first, the gas-liquid-solid mixed medium is introduced tangentially from the spiral air inlet pipe 501 in the middle of the separation tank 1, and a swirl is generated between the spiral channels formed by the upper and lower adjacent spiral plates 502, so that solid impurities are stripped from the mixed medium, and enter from the inner side of the discharge hole 503 at the end of the spiral channel, and then pass through the discharge hole 503 outside the inner recess 504 and fall into the solid storage area 6. On the one hand, the present application preferentially realizes the stripping and discharge of solid impurities before the gas-liquid separation process, thereby effectively reducing the risk of system blockage caused by the presence of solid impurities in the mixed medium. On the other hand, the solid impurities and liquid medium are classified and collected to reduce the cleaning difficulty caused by the solid-liquid mixture collected at the bottom of the tank. Secondly, The gas-liquid mixed medium from which solid impurities have been stripped enters through the side notch of the outer sleeve 402 arranged in an array on the outer edge of the lower partition 401, and generates a swirl under the action of the swirl blades 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 is gathered inwardly and discharged upwardly through the internal channel of the inner sleeve 405, thereby achieving efficient gas-liquid separation. At the same time, the possibility of liquid medium splashing into gas medium is avoided through the design of inner and outer double sleeves, which can improve the purity and separation effect of the gas medium. In addition, the present application arranges multiple sets of matching components in an array on the lower partition 401 The inner and outer double sleeves are arranged so that even if one of them is blocked by impurities, the other can still be separated normally, thereby ensuring the overall separation capacity of the separator. Furthermore, when the swirl blade 403 rotates and generates a swirl under the impetus of the gas-liquid mixed medium, the swirl blade 403 is meshed with the driven wheel 506 at the bottom of the rotating rod 505 through the outer edge gear ring 404, thereby driving the belt 507 sleeved on the top of the rotating rod 505 to rotate, so that the cleaning sheet 508 hinged on the outside of the belt 507 fits the discharge holes 503 on both sides of the inner recess 504 for scraping and cleaning, so that the present application can simultaneously self-clean the channel required for the discharge of solid impurities while performing the gas-liquid separation operation. This process does not rely on the power provided by an external prime mover, but uses the kinetic energy of the mixed medium flowing in to It is converted into mechanical energy for the rotation of the self-cleaning device, providing a continuous power output for the self-cleaning of the discharge hole 503, and has stronger applicability. Finally, there may still be some liquid residue in the gas phase medium that is passed from the inner sleeve 405 from bottom to top into the buffer zone 8 at the top of the separation tank 1. Therefore, the present application sets a secondary filtration component 10 inside the buffer zone 8, and radially arranges several baffles 1004 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 is merged into the liquid storage area 2 through the reflux pipe 1006 vertically connected to the notch at the top of the guide platform 1005. The present application cooperates with the gas-liquid separation component 4 and the secondary filtration component 10, and uses the redundant design of two filtration processes.Further improve the purity and separation effect of the gas phase medium, so that the intake medium entering the turbine vacuum machine from the top connection flange 1002 of the cylinder 1001 is completely saturated gas medium, ensuring that the core component of the turbine vacuum machine, the impeller, does not experience cavitation caused by droplets and fracture caused by solid particles, thereby ensuring the safe operation of the turbine vacuum machine.
