Description

Technical Field

[0001] The present invention relates to the technical field of fluid automatic separation, in particular to a mechanical multi-purpose high-pressure automatic separation device. Background Art

[0002] Mechanical multi-purpose high-pressure automatic separation device is a device designed based on the principle of gravity, used to separate gas and liquid (or two liquids with different specific gravities, where the liquid with a smaller specific gravity is also called light liquid and the liquid with a larger specific gravity is also called heavy liquid). To improve separation efficiency, the device is usually equipped with a condensation filter. The main function of the condensation filter is to gather liquid (or heavy liquid) droplets suspended in the gas (or light liquid), causing these droplets to coalesce into larger droplets in the tiny channels within the condensation filter. When the mass of the droplets exceeds the surface tension between them and the filter surface, the droplets will break away from the filter and drip to the bottom, thereby achieving more thorough gas-liquid (or liquid-liquid) separation. However, in actual use, when there is too much liquid (or heavy liquid) mixed with the gas (or light liquid), more liquid (or heavy liquid) will accumulate in the condensation filter, reducing the flow area of ​​the gas (or light liquid) in the condensation filter, thereby increasing the pressure of the gas (or light liquid) flowing through it. This increase in pressure makes it easier for the gas (or light liquid) to push the liquid (or heavy liquid) in the condensation filter to flow upward, making it difficult for the liquid (or heavy liquid) to separate from the filter, or even re-entering the gas (or light liquid). This will undoubtedly reduce the separation accuracy of the existing device and the overall performance of the separation device. Summary of the Invention

The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0033] Mechanical multi-purpose high-pressure automatic separation device, reference Figures 1-6 , including a shell 1, the shell 1 is fixedly connected to and communicated with a first discharge pipe 101, a second discharge pipe 102, an automatic balancing valve 103 and a feed pipe 2, the shell 1 is fixedly connected to a fixing frame 3, the fixing frame 3 is provided with flow guide holes 31 arranged at intervals, and a coalescing separation filter element 4 is installed in the flow guide hole 31, the fixing frame 3 is fixedly connected to circumferentially distributed fixing columns 5, the fixed columns 5 are fixedly connected to flow guide covers 6 distributed at intervals, the flow guide covers 6 are communicated with adjacent flow guide holes 31, the flow guide covers 6 are fixedly connected to and communicated with a backflush pipe 7, a control valve 71 is installed on the backflush pipe 7, the backflush pipe 7 is used to backflush the adjacent coalescing separation filter element 4, a detection mechanism is provided in the flow guide cover 6, the detection mechanism is used to detect the flow pressure of the fluid in the adjacent flow guide holes 31, and a blocking mechanism is provided in the shell 1, the blocking mechanism is used to prevent gas or light liquid from entering the automatic balancing valve 103.

[0034] Furthermore, reference Figure 5-Figure 7 The detection mechanism includes a first mounting bracket 61, which is fixed in the air deflector 6. The first mounting bracket 61 is slidably connected to a sliding plug 62, and a first spring is installed between the two. The sliding plug 62 contacts the air deflector 6, and the air deflector 6 is slidably connected to a sliding rod 72 through a sealing shell. The sliding rod 72 and the valve stem of the control valve 71 are transmitted through a gear rack. The sliding rod 72 is fixed to an extrusion block 73, which is located on the moving path of the sliding plug 62. A second spring is installed between the extrusion block 73 and the upper bracket of the air deflector 6.

[0035] Furthermore, reference Figure 2-Figure 4 The feed pipe 2 is fixedly connected with a liquid spray shell 21. The outer shell 1 and the feed pipe 2 are both connected to the liquid spray shell 21. The liquid spray shell 21 is used to spray the material into the outer shell 1 along the horizontal direction.

[0036] In the above scheme, the first discharge pipe 101 is located on the upper side of the shell 1 and is used to discharge gas or light liquid. The automatic balancing valve 103 is located on the lower side of the shell 1. The automatic balancing valve 103 is an existing device and is used to discharge liquid or heavy liquid. The second discharge pipe 102 is located at the bottom of the shell 1 and is used to treat and discharge the waste liquid in the shell 1. The feed pipe 2 is located between the first discharge pipe 101 and the second discharge pipe 102 and is used to add a gas-liquid mixed material or two materials with different specific gravities that are mixed with each other into the shell 1; the coalescing separation filter element 4 is an existing device, and the sliding plug 62 is inserted into the guide cover 6 to seal the guide cover 6. The backflush pipe 7 is connected to the external supply system, and the gas (or light liquid) ejected from the backflush pipe 7 is separated from the gas (or light liquid) obtained by separating the material. The pressure of the gas (or light liquid) ejected from the recoil pipe 7 is lower than the pressure of the gas or liquid flowing in the adjacent guide hole 31 when no blockage occurs, thereby preventing the gas (or light liquid) ejected from the recoil pipe 7 from squeezing the sliding plug 62 upward, thereby preventing the sliding plug 62 from releasing the sealing relationship with the guide cover 6; the elastic coefficient of the first spring on the sliding plug 62 is greater than the elastic coefficient of the second spring on the extrusion block 73, and the initial state of the second spring on the extrusion block 73 is a compressed state. The supply system and the sealing mechanism are both electrically connected to the control terminal. The liquid spray shell 21 is provided with circumferentially distributed liquid spray nozzles, and the liquid spray shell 21 sprays the material horizontally into the outer shell 1 through the liquid spray nozzles, thereby promoting the uniformity of the upward flow of the gas in the material.

[0037] The working process is as follows: when the staff is preparing to separate the material, assuming that the material is mainly composed of gas and liquid, the material needs to be separated from the gas-liquid. The staff passes the material into the feed pipe 2 and opens the supply system and the blocking mechanism through the control terminal. The feed pipe 2 sprays the material into the outer shell 1 through the liquid spray shell 21. At this time, the gas naturally floats upward and the liquid naturally flows downward. During the upward floating process, the gas flows into the adjacent guide hole 31. At this time, taking a group of guide holes 31 and adjacent parts as an example, after the gas enters the guide hole 31, it first enters the coalescence Inside the separation filter element 4, the suspended liquid in the gas gradually sticks to the coalescing separation filter element 4. The gas passes through the coalescing separation filter element 4 and enters the guide cover 6. The sliding plug 62 is squeezed upward by the gas flow pressure. At the same time, the squeezing block 73 gradually extends into the guide cover 6 under the action of the second spring on it. The first spring on the sliding plug 62 is compressed and accumulates force, so that the gas continues to flow upward through the sliding plug 62. The gas is finally discharged outward from the first discharge pipe 101, and the separated liquid passes through the sealing mechanism and is discharged outward from the automatic balancing valve 103.

[0038] When a large amount of liquid accumulates in the coalescing separation filter element 4 and the liquid is too dispersed to condense into droplets, the cross-sectional area for gas flow in the coalescing separation filter element 4 decreases. At this time, the pressure required for gas to pass through the coalescing separation filter element 4 increases, and the gas in the housing 1 tends to flow upward through the coalescing separation filter element 4 where the resistance is smaller. Therefore, the amount of gas flowing in the coalescing separation filter element 4 where the resistance is smaller decreases, and the gas flow pressure decreases synchronously. At this time, the sliding plug 62 moves downward and resets under the action of the adjacent first spring, blocking the adjacent guide cover 6. During the movement of the sliding plug 62, the squeezing block 73 is squeezed to move out of the guide cover 6. The second spring on the squeezing block 73 is compressed and stored, and the squeezing block 73 drives the sliding rod 72 to move. The sliding rod 72 drives the control valve 71 to open through the gear rack, and the supply system is connected to the backflush pipe 7. The backflush pipe 7 sprays gas into the adjacent guide cover 6 (this gas is consistent with the gas obtained by material separation). At this time, since the guide cover 6 is blocked by the sliding plug 62, the gas pressure is not enough to push the sliding plug 62 upward. Therefore, the gas can only flow downward, and the gas passes through the coalescing separation filter element 4 in the opposite direction. The separation filter element 4 promotes the liquid intercepted in the coalescing separation filter element 4 to flow downward. Under the dual action of gravity and gas flow, the liquid in the coalescing separation filter element 4 gradually gathers to the bottom of the coalescing separation filter element 4. At this time, the liquid is deposited at the bottom of the coalescing separation filter element 4 and is more likely to gather into droplets. After the droplets are formed, they drip downward and separate from the coalescing separation filter element 4. The liquid content in the coalescing separation filter element 4 is reduced. At this time, the resistance of the gas in the housing 1 to pass through the coalescing separation filter element 4 is reduced, and the gas in the housing 1 passes through the coalescing separation filter element 4 again and flows upward, and The extrusion sliding plug 62 moves upward, and the first spring on the sliding plug 62 is compressed and stored again. The sliding plug 62 moves and no longer squeezes the extrusion block 73. The extrusion block 73, the sliding rod 72 and the control valve 71 are reset under the elastic force of the second spring on the extrusion block 73. Through the cooperation of the sliding plug 62 and the extrusion block 73, the coalescence separation filter element 4 is automatically backflushed and cleaned when the liquid content in the adjacent coalescence separation filter element 4 is high, so that the separation accuracy of the coalescence separation filter element 4 is always maintained at a high state, thereby improving the overall separation performance of the device.

[0039] When all materials are separated, the staff cleans the shell 1 and discharges the cleaned waste liquid in the shell 1 through the second discharge pipe 102. Then the staff closes the blocking mechanism and the supply system through the control terminal. When the staff needs to separate two liquids with different specific gravities, the flow path of the light liquid is the same as the flow path of the gas in the above-mentioned gas-liquid separation process, and the flow path of the heavy liquid is the same as the flow path of the liquid in the above-mentioned gas-liquid separation process. The backflush pipe 7 no longer sprays out gas, but directly sprays out light liquid. This device separates the two liquids according to the same principle as above.

[0040] Furthermore, reference Figure 2 and Figures 9-11The sealing mechanism includes a second mounting frame 10, which is fixed to the outer shell 1. The second mounting frame 10 is fixed to a fixed disk 11. The fixed disk 11 is slidably connected to a sliding seal 12. The sliding seal 12 is used to detect the height of the liquid level. A liquid storage cavity 121 is provided in the sliding seal 12. An adjusting component is provided in the sliding seal 12. The adjusting component is used to change the specific gravity of the liquid storage cavity 121 according to the density of the solution in the outer shell 1.

[0041] Furthermore, reference Figure 10-12 The regulating component includes an air intake pipe 13, which is fixed to the sliding seal 12, and the air intake pipe 13 is connected to the liquid storage chamber 121. The sliding seal 12 is fixed with a return air pipe 131, a liquid inlet pipe 14 and a return liquid pipe 141. The return air pipe 131, the liquid inlet pipe 14 and the return liquid pipe 141 are all connected to the liquid storage chamber 121. The air intake pipe 13, the return air pipe 131, the liquid inlet pipe 14 and the return liquid pipe 141 are all installed with ball valves. A control component is provided on the sliding seal 12, and the control component is used to control the opening and closing of the ball valves on the air intake pipe 13, the return air pipe 131, the liquid inlet pipe 14 and the return liquid pipe 141.

[0042] In the above content, since the content of liquid (or heavy liquid) in the material is unstable during gas-liquid separation (or liquid-liquid separation), the efficiency of the automatic balancing valve 103 in discharging the liquid (or heavy liquid) is uncertain. The blocking mechanism is intended to discharge the liquid (or heavy liquid) from the housing 1 while preventing the liquid (or heavy liquid) from being completely discharged in a short period of time, thereby causing gas (or light liquid) to enter the automatic balancing valve 103. The lower part of the sliding seal 12 is spherical. The automatic balancing valve 103 can be an electrically controlled valve or a mechanically controlled valve. In this solution, a mechanically controlled valve structure is adopted. The automatic balancing valve 103 judges the liquid level of the liquid (or heavy liquid) by detecting the floating height of the sliding seal 12 through mechanical transmission (because the automatic balancing valve 103 is an existing device, the automatic balancing valve 103 and its internal components are not shown in detail in the figure); the air inlet pipe 13 and the air return pipe 131 are located on the upper side of the liquid storage chamber 121, and the liquid inlet pipe 14 and the liquid return pipe 141 are connected to the liquid storage chamber 121. The connection is located at the lower side of the liquid storage chamber 121. The density of the liquid discharged into the liquid storage chamber 121 by the liquid inlet pipe 14 is greater than the density of the heavy liquid (because the density of the sliding seal 12 is always greater than the density of the gas, there is no need to discharge liquid into the liquid storage chamber 121 during gas-liquid separation, and liquid is only required to be discharged into the liquid storage chamber 121 during liquid-liquid separation). It is used to increase the specific gravity of the sliding seal 12, so that the specific gravity of the sliding seal 12 can be adjusted to be slightly less than the specific gravity of the heavy liquid, so that when the bottom of the device is When the liquid level (or heavy liquid) reaches a certain height (the height value can be manually adjusted), the sliding seal 12 rises under the buoyancy of the liquid (or heavy liquid), and the automatic balancing valve 103 opens to facilitate the discharge of the liquid (or heavy liquid). When the liquid level (or heavy liquid) drops to a certain height, the automatic balancing valve 103 closes to prevent the gas (or light liquid) from being discharged outward through the automatic balancing valve 103. The valve operates reciprocatingly to discharge the liquid (or heavy liquid) out of the housing 1.

[0043] Furthermore, reference Figure 11-13 The control component includes a first gear 132, which is fixedly connected to the valve stem of the ball valve on the intake pipe 13, the valve stem of the ball valve on the return pipe 131 is fixedly connected to the valve stem of the ball valve on the intake pipe 13, the valve stem of the ball valve on the liquid return pipe 141 is installed with a transmission gear meshing with the first gear 132, and the valve stem of the ball valve on the liquid inlet pipe 14 is fixedly connected with the second gear 142. The sliding seal 12 is fixedly connected to two third mounting brackets 15, and the third mounting bracket 15 is slidably connected to the sliding member 16, and a third spring is installed between the two. A rack is provided on the sliding member 16, and the first gear 132 and the second gear 142 are respectively meshed with the racks on the adjacent sliding members 16, and the sliding member 16 is slidably connected to the sliding block 17. The fixed disk 11 is fixed with two electromagnets 18, and the electromagnet 18 and the adjacent sliding blocks 17 are magnetically attracted to each other. The sliding block 17 is provided with a regulating component for closing the adjacent electromagnet 18.

[0044] Furthermore, reference Figure 13 and Figure 14 The regulating component includes symmetrically distributed micro-touch switches 19, which are all fixed to adjacent sliding blocks 17. A symmetrically distributed fourth spring is installed between the sliding member 16 and the adjacent sliding block 17. The sliding member 16 is fixed with symmetrically distributed protrusions 191, which are used to squeeze and trigger the micro-touch switches 19.

[0045] In the above content, the electromagnet 18 is electrically connected to the control terminal, and the micro-touch switch 19 is electrically connected to the control terminal. When the micro-touch switch 19 is triggered, the control terminal cuts off the circuit on the electromagnet 18. When the sliding block 17 is magnetically attracted by the adjacent electromagnet 18, the two contact each other, and the contact surface of the sliding block 17 and the adjacent electromagnet 18 is a friction surface. It is difficult for the two to move up and down relative to each other after being magnetically attracted; initially, the ball valve on the return pipe 131 is in the open state, and the ball valve on the intake pipe 13 is in the closed state. The valve stems of the ball valves on the two are fixedly connected, so when the ball valve on the intake pipe 13 is opened, the ball valve on the return pipe 131 enters the closed state at the same time. Initially, the ball valve on the liquid inlet pipe 14 and the ball valve on the return liquid pipe 141 are also in the closed state. When the first gear 132 drives the ball valve on the intake pipe 13 to rotate and open The first gear 132 drives the transmission gear on the ball valve stem of the liquid return pipe 141 to rotate, so that the ball valve on the liquid return pipe 141 rotates and opens synchronously; the air inlet pipe 13 is connected to the external air supply system, the air return pipe 131 is connected to the outside, and the liquid inlet pipe 14 and the liquid return pipe 141 are connected to the external liquid supply system. The air supply system and the liquid supply system are both existing technologies. An exhaust device is installed in the liquid supply system to discharge the mixed gas in the liquid supply system, wherein the liquid inlet pipe 14 is used to fill liquid into the liquid storage chamber 121, and the liquid return pipe 141 is used to discharge the liquid in the liquid storage chamber 121. Both the air return pipe 131 and the liquid return pipe 141 are provided with a one-way valve. The air return pipe 131 can only allow the gas in the liquid storage chamber 121 to flow outward, and the liquid return pipe 141 can only allow the gas and liquid in the liquid storage chamber 121 to flow outward.

[0046] The working process is as follows: when the staff is ready to perform gas-liquid separation, they first start the air supply system and the liquid supply system through the control terminal, and then start the electromagnet 18 near the air inlet pipe 13. The electromagnet 18 is magnetized to attract the sliding block 17 near the air inlet pipe 13, and the sliding block 17 drives the sliding member 16 to slide. The third spring on the sliding member 16 is compressed and stores force, and the sliding member 16 drives the first gear 132 to rotate through the rack thereon, and the first gear 132 drives the transmission gear on the ball valve of the return liquid pipe 141 to rotate. At this time, the ball valve on the air inlet pipe 13 and the ball valve on the return liquid pipe 141 are opened, and the ball valve on the return air pipe 131 is closed. The gas in the air supply system flows into the liquid storage chamber 121 through the air inlet pipe 13. Because the return air pipe 131 is closed, the gas cannot be discharged from the return air pipe 131. The residual liquid in the liquid storage chamber 121 is pushed by the gas and discharged from the return liquid pipe 141 to the liquid supply system. When the liquid in the liquid storage chamber 121 is completely discharged, the liquid storage chamber After part of the gas in 121 enters the liquid supply system through the return liquid pipe 141, it is discharged outward by the exhaust device in the liquid supply system. When the liquid storage chamber 121 is completely filled with air, the control terminal closes the electromagnet 18, and the sliding member 16 moves to the left and resets under the action of the third spring. The ball valve on the intake pipe 13, the ball valve on the return air pipe 131 and the ball valve on the return liquid pipe 141 are all restored to their initial state. The specific gravity of the sliding seal 12 is less than that of the liquid, so it will float on the surface of the liquid. At this time, the staff performs gas-liquid separation work according to the above content. When the liquid level drops, the floating height of the sliding seal 12 is lower than a certain height, the sliding seal 12 controls the automatic balancing valve 103 to close automatically. When the liquid level reaches a certain height, the sliding seal 12 floats upward under the action of the buoyancy of the liquid, and the sliding seal 12 controls the automatic balancing valve 103 to open. At this time, the liquid is discharged outward from the automatic balancing valve 103.

[0047] When the staff is ready to perform liquid-liquid separation, the staff starts the electromagnet 18 near the liquid inlet pipe 14. The electromagnet 18 is magnetized to attract the sliding member 16 and the sliding block 17 near the liquid inlet pipe 14 to move. The third spring on the sliding member 16 is compressed and stored, so that the ball valve on the liquid inlet pipe 14 is opened. At this time, the liquid supply system supplies liquid to the liquid storage chamber 121 through the liquid inlet pipe 14, and the gas in the liquid storage chamber 121 is discharged outwardly through the return pipe 131. When the liquid storage chamber 121 is filled with liquid, the staff closes the electromagnet 18 near the liquid inlet pipe 14, so that the sliding member 16 and the sliding block 17 are in the sliding position. The movable member 16 moves back to its original position under the action of the adjacent third spring, and the liquid inlet pipe 14 is closed. At this time, the specific gravity of the sliding seal 12 is greater than that of the heavy liquid. The staff then starts the device to perform liquid-liquid separation. After a certain period of liquid-liquid separation, the heavy liquid cannot float the sliding seal 12, and the automatic balancing valve 103 is always in a closed state. Therefore, the heavy liquid accumulates at the bottom of the housing 1. The staff then starts the electromagnet 18 near the air inlet pipe 13, and the ball valve on the air inlet pipe 13 is opened. The air supply system is then fed into the liquid storage chamber 121 in the same manner as above. Air is supplied. At this time, the sliding block 17 contacts the adjacent electromagnet 18, and the two cannot move relative to each other. The liquid in the liquid storage chamber 121 is discharged into the liquid supply system under the pressure of the gas, and the specific gravity of the sliding seal 12 gradually decreases. When the specific gravity of the sliding seal 12 decreases to less than the specific gravity of the heavy liquid, the sliding seal 12 moves upward under the buoyancy of the heavy liquid. At this time, the sliding seal 12 drives the sliding member 16 to move upward through the third mounting bracket 15. The fourth spring on the upper side of the sliding member 16 is compressed and stored, and the fourth spring on the lower side of the sliding member 16 is stretched and stored. The sliding member 16 drives the protrusion 19 1 moves and contacts the micro-touch switch 19 on the upper side. The micro-touch switch 19 transmits a signal to the control terminal, which turns off the electromagnet 18 near the air inlet pipe 13. The sliding block 17 and the sliding member 16 move and reset under the action of the third spring and the fourth spring on the adjacent sliding member 16. At this time, since the ball valve on the air inlet pipe 13 is closed, no new gas will enter the liquid storage chamber 121. Therefore, the specific gravity of the sliding seal 12 is only slightly smaller than that of the heavy liquid, which increases the difference between the specific gravity of the sliding seal 12 and the specific gravity of the light liquid, and reduces the probability of the light liquid entering the automatic balancing valve 103.

[0048] After the staff completes the liquid-liquid separation work, the liquid in the sliding seal 12 is emptied in the same manner, and the liquid supply system and the air supply system are closed.

[0049] Furthermore, reference Figure 4-Figure 6 and Figure 8 , and also includes sponges 8 distributed at intervals. The number of sponges 8 is consistent with the number of coalescing and separating filter elements 4 and corresponds one to one. The sponges 8 are fixed to the upper side of adjacent coalescing and separating filter elements 4.

[0050] Furthermore, reference Figure 8 A horizontal through hole is provided in the sponge 8. An extrusion piece 81 is fixedly connected to the upper side of the sponge 8. A tension spring is fixedly connected between the extrusion piece 81 and the adjacent air deflector 6. An extrusion column 82 is fixedly connected to the sliding plug 62. The extrusion column 82 is in extrusion contact with the extrusion piece 81.

[0051] In the above scheme, the sponge 8 is used to adjust the resistance of gas flow. When the gas in the recoil tube 7 flows downward, there is resistance when the gas penetrates the sponge 8, which prompts the gas to disperse on the upper side of the sponge 8, and then the gas penetrates from the upper side of the sponge 8 to the lower side of the sponge 8 in a uniform penetration manner, thereby making the gas flowing downward in the coalescence separation filter element 4 more uniform, increasing the coverage area when the gas recoils the coalescence separation filter element 4, and by providing a horizontal through hole on the sponge 8, the resistance of the gas passing through the sponge 8 is adjusted. The state of the sponge 8 when compressed is as follows: Figure 5 and Figure 6 As shown, the state of sponge 8 when not compressed is as follows Figure 8 As shown, the elastic coefficient of the tension spring on the extrusion member 81 is smaller than the elastic coefficient of the first spring on the sliding plug 62 , and the initial state of the tension spring on the extrusion member 81 is a force storage state.

[0052] The working process is as follows: when the liquid content in the coalescence separation filter element 4 is low, the gas squeezes the sliding plug 62 to move upward, and the sliding plug 62 is separated from the guide cover 6. At this time, the squeezing force between the squeezing column 82 on the sliding plug 62 and the squeezing member 81 is lost, and the squeezing column 82 moves upward with the sliding plug 62. The squeezing member 81 moves upward synchronously under the action of the tension spring on it, and the squeezing member 81 drives the sponge 8 to stretch to Figure 8 In the state shown, the kinetic energy lost by the gas when passing through the sponge 8 is small. When the liquid content in the coalescing separation filter element 4 is large and the gas no longer flows upward through the coalescing separation filter element 4, the sliding plug 62 moves downward and resets under the action of the first spring thereon. The sliding plug 62 squeezes the extrusion member 81 downward through the extrusion column 82, and the tension spring on the extrusion member 81 stretches and accumulates force, and the extrusion member 81 drives the sponge 8 to contract downward, so that the through holes on the sponge 8 gradually disappear (as shown in FIG. Figure 5 and Figure 6 As shown), the resistance of the gas passing through the sponge 8 is increased, and the uniformity of the gas flowing downward through the sponge 8 in the recoil tube 7 is increased.

[0053] Furthermore, reference Figure 2 、 Figure 3 and Figure 6 , and also includes pneumatic telescopic rods 9 distributed at intervals. The number of pneumatic telescopic rods 9 is consistent with the number of air deflectors 6 and corresponds one to one. The pneumatic telescopic rods 9 are fixed to the adjacent first mounting brackets 61. The telescopic ends of the pneumatic telescopic rods 9 are fixed to the adjacent sliding plugs 62. All the pneumatic telescopic rods 9 on the same fixed column 5 are connected to each other.

[0054] In the above scheme, under normal circumstances, the liquid content in the flowing gas in different guide holes 31 is different, resulting in different liquid contents retained in different coalescing separation filter elements 4. As the coalescing separation filter element 4 is used, the liquid content in each coalescing separation filter element 4 tends to gradually increase. Therefore, there will be a majority of coalescing separation filter elements 4 that trigger the above-mentioned backflushing process for the coalescing separation filter element 4, resulting in large-scale gas fluctuations in the remaining coalescing separation filter elements 4, affecting the smoothness of the filtration process of the device. The above scheme aims to propose a According to the content of retained liquid in different coalescing and separating filter elements 4, different coalescing and separating filter elements 4 are cleaned in order from the one with the most retained liquid to the one with the least retained liquid, so as to maintain the smooth operation of the device; all the pneumatic telescopic rods 9 on the same fixed column 5 are interconnected, and are called a group of pneumatic telescopic rods 9 (in this scheme, there are three pneumatic telescopic rods 9 in a group), and there is only one pneumatic telescopic rod 9 capacity of gas in each group of pneumatic telescopic rods 9, so at the same time, only one telescopic end of the pneumatic telescopic rod 9 can be extended to the longest state.

[0055] The working process is as follows: taking all the pneumatic telescopic rods 9 on a fixed column 5, i.e., adjacent components (i.e., pneumatic telescopic rods 9 in the same group) as an example, in the initial state, the gas flow resistance in the three guide holes 31 is similar, and the force of the gas pushing the three sliding plugs 62 is equal. Therefore, at this time, the telescopic ends of the three pneumatic telescopic rods 9 extend by the same distance. When the liquid content in one of the coalescing separation filter elements 4 increases, the gas flow resistance in the guide hole 31 increases, and the amount of gas in the guide hole 31 decreases. At this time, the amount of gas in the other two guide holes 31 increases. Therefore, the gas thrust on the sliding plug 62 at the guide hole 31 where the gas amount decreases decreases, and the gas thrust on the other two sliding plugs 62 increases. The other two sliding plugs 62 respectively drive the telescopic ends of the two adjacent pneumatic telescopic rods 9 to retract, squeezing all the gas into the pneumatic telescopic rods 9 at the guide hole 31 where the gas amount decreases. The telescopic end of the pneumatic telescopic rod 9 extends downward, and the sliding plug 62 at this location moves downward, triggering the adjacent backflush pipe 7 to backflush the coalescing separation filter element 4. When When the liquid content at the coalescence separation filter element 4 decreases, the resistance of the gas passing through the coalescence separation filter element 4 is reduced to less than the resistance at the other two coalescence separation filter elements 4. At this time, the gas pushes the sliding plug 62 and adjacent components there to move and reset. When there is a difference in the liquid content in the other two coalescence separation filter elements 4, the device backflushes the coalescence separation filter element 4 with higher liquid content according to the above working principle and the same process, without waiting until the thrust of the gas at the coalescence separation filter element 4 is less than the spring force on the sliding plug 62 before backflushing the coalescence separation filter element 4. This increases the smoothness of the gas separation of the device and reduces the probability of air flow fluctuations in other coalescence separation filter elements 4 when multiple coalescence separation filter elements 4 are backflushed at the same time. When all materials are separated, there is no more gas flowing in all the guide holes 31. At this time, all the sliding plugs 62 move to the same height under the elastic force of the adjacent first springs, and the telescopic ends of all the pneumatic telescopic rods 9 extend to the same length.
