Description

Technical Field

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

[0002] The mechanical multi-purpose high-pressure automatic separation device is a device designed based on the principle of gravity, used for separating gases and liquids (or two liquids with different specific gravities, where the liquid with a smaller specific gravity is also called the light liquid, and the liquid with a larger specific gravity is also called the heavy liquid). To improve the separation efficiency, the device is usually equipped with a condensation filter. The main function of the condensation filter is to gather the liquid (or heavy liquid) droplets suspended in the gas (or light liquid), so that these droplets coalesce into larger droplets in the fine channels of the condensation filter. When the mass of the droplet exceeds the surface tension between it and the filter surface, the droplet will break away from the filter and drip to the bottom, thereby achieving a more thorough gas-liquid (or liquid-liquid) separation. However, in actual use, when there is too much liquid (or heavy liquid) mixed in the gas (or light liquid), it will cause more liquid (or heavy liquid) to accumulate in the condensation filter, reducing the flow area of the gas (or light liquid) in the condensation filter, thus increasing the pressure of the gas (or light liquid) flowing through. This increase in pressure will make 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 and even re-enter the gas (or light liquid). This will undoubtedly lead to a reduction in the separation accuracy of the existing device and a decline in the overall performance of the separation device. Summary of the Invention

[0007] Furthermore, the plugging mechanism includes a second mounting bracket fixedly connected inside the outer shell. The second mounting bracket is fixedly connected with a fixed disk. The fixed disk is slidably connected with a sliding seal. The sliding seal is used for detecting the liquid level height. A liquid storage cavity is arranged inside the sliding seal. An adjusting component is arranged inside the sliding seal. The adjusting component is used for changing the specific gravity of the liquid storage cavity according to the density of the solution inside the outer shell.

[0008] Furthermore, the adjusting component includes an air inlet pipe fixedly connected to the sliding seal, and the air inlet pipe is communicated with the liquid storage cavity. The sliding seal is fixedly connected with a return air pipe, a liquid inlet pipe and a liquid return pipe. The return air pipe, the liquid inlet pipe and the liquid return pipe are all communicated with the liquid storage cavity.

[0009] Furthermore, the control component includes a first gear fixedly connected to the valve rod of the ball valve on the air inlet pipe.

The fixed disk is fixedly connected with two electromagnets. The electromagnets and the adjacent sliding blocks are magnetically attracted to each other.

[0014] The beneficial effects of the present invention are as follows: The present invention performs backwashing on the coalescing separation filter through the backwash pipe, assisting the accumulated gas or light liquid in the coalescing separation filter to discharge downward, improving the separation efficiency of the coalescing separation filter, reducing the probability of heavy liquid entering the gas or light liquid, and making the separation more thorough.

[0015] The present invention increases the uniformity of the backwash gas or light liquid through the sponge. At the same time, the influence of the sponge on the normal separation work is reduced by using the extrusion member. Due to the characteristic that the pneumatic telescopic rods on the fixed column are interconnected, the coalescing separation filter with relatively more liquid content is backwashed and cleaned in advance, increasing the stability and reliability of the device.

The present invention can also be implemented or applied through different specific implementation manners. Various 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, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0020] Mechanical multi-purpose high-pressure automatic separation device, refer to Figures 1-6 , including a housing 1, the housing 1 is fixedly connected and communicated with a first discharge pipe 101, a second discharge pipe 102, an automatic balance valve 103 and a feed pipe 2. The housing 1 is fixedly connected with a fixing frame 3. The fixing frame 3 is provided with coalescing separation filters 4 installed in spaced-apart flow guiding holes 31. The fixing frame 3 is fixedly connected with circumferentially distributed fixing columns 5. The fixing columns 5 are fixedly connected with spaced-apart flow guiding covers 6. The flow guiding covers 6 are communicated with adjacent flow guiding holes 31. The flow guiding covers 6 are fixedly connected and communicated with backflush pipes 7. Control valves 71 are installed on the backflush pipes 7. The backflush pipes 7 are used for backflushing adjacent coalescing separation filters 4. A detection mechanism is arranged in the flow guiding covers 6. The detection mechanism is used for detecting the flow pressure of the fluid in the adjacent flow guiding holes 31. A blocking mechanism is arranged in the housing 1. The blocking mechanism is used for preventing gas or light liquid from entering the automatic balance valve 103.

[0021] Furthermore, refer to Figures 5-7 , the detection mechanism includes a first mounting frame 61. The first mounting frame 61 is fixedly connected in the flow guiding cover 6. The first mounting frame 61 is slidably connected with a sliding plug 62, and a first spring is installed between the two. The sliding plug 62 is in contact with the flow guiding cover 6. The flow guiding cover 6 is slidably connected with a sliding rod 72 through a sealing shell. The sliding rod 72 is in gear-rack transmission with the valve stem of the control valve 71. The sliding rod 72 is fixedly connected with an extrusion block 73. The extrusion block 73 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 flow guiding cover 6.

[0022] Furthermore, refer to Figures 2-4 , the feed pipe 2 is fixedly connected with a liquid spraying shell 21. The housing 1 and the feed pipe 2 are both communicated with the liquid spraying shell 21. The liquid spraying shell 21 is used for spraying materials into the housing 1 in the horizontal direction.

[0023] In the above solution, the first discharge pipe 101 is located on the upper side of the outer shell 1 and is used to discharge gas or light liquid. The automatic balance valve 103 is located on the lower side of the outer shell 1. The automatic balance 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 outer shell 1 and is used to process and discharge the waste liquid in the outer 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 mixture of materials or two materials with different specific gravities and mixed with each other into the outer shell 1. The coalescing and separating filter element 4 is an existing device. The sliding plug 62 plugs the flow guide cover 6 by inserting into it. The backflush pipe 7 is communicated with an external supply system. The gas (or light liquid) ejected from the backflush pipe 7 is the same as the gas (or light liquid) obtained by separating the material. The pressure of the gas (or light liquid) ejected from the backflush pipe 7 is less than the pressure when the gas or liquid flows in the adjacent flow guide holes 31 when they are not blocked, so as to prevent the gas (or light liquid) ejected from the backflush pipe 7 from squeezing the sliding plug 62 to move upward, and further prevent the sliding plug 62 from releasing the sealing relationship with the flow 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. The second spring on the extrusion block 73 is in a compressed state in the initial state. Both the supply system and the plugging mechanism are electrically connected to the control terminal. The liquid spraying shell 21 is provided with liquid spraying nozzles distributed circumferentially. The liquid spraying shell 21 sprays the material horizontally into the outer shell 1 through the liquid spraying nozzles, thereby promoting the uniformity of the upward flow of the gas in the material.

[0024] 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 and needs to be gas-liquid separated, the staff feeds the material into the feed pipe 2 and turns on the supply system and the plugging mechanism through the control terminal. The feed pipe 2 sprays the material into the outer shell 1 through the liquid spraying shell 21. At this time, the gas naturally floats upward and the liquid naturally flows downward. During the upward floating process of the gas, it flows into the adjacent flow guide holes 31. At this time, taking a group of flow guide holes 31 and adjacent components as an example, after the gas enters the flow guide holes 31, it first enters the coalescing and separating filter element 4. At this time, the suspended liquid in the gas gradually adheres to the inside of the coalescing and separating filter element 4. After the gas passes through the coalescing and separating filter element 4, it enters the flow guide cover 6 and squeezes the sliding plug 62 to move upward through the gas flow pressure. At the same time, the extrusion block 73 gradually extends into the flow guide cover 6 under the action of its second spring, and the first spring on the sliding plug 62 compresses and stores energy, 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 plugging mechanism and is discharged outward from the automatic balance valve 103.

[0025] When there is a large amount of liquid accumulated 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 the gas to pass through the coalescing separation filter element 4 increases. The gas in the housing 1 is more inclined to flow upward through the coalescing separation filter element 4 at the location with less resistance. Therefore, the amount of gas flowing through the coalescing separation filter element 4 with less resistance 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 flow guide cover 6. During the movement of the sliding plug 62, it squeezes the extrusion block 73 to move outward of the flow guide cover 6, and the second spring on the extrusion block 73 compresses and stores energy. The extrusion block 73 drives the sliding rod 72 to move, and the sliding rod 72 drives the control valve 71 to open through the gear and rack, connecting the supply system with the backflush pipe 7. The backflush pipe 7 sprays gas (the same as the gas obtained by separating the material) into the adjacent flow guide cover 6. At this time, since the flow guide cover 6 is blocked by the sliding plug 62 and the gas pressure is not sufficient to push the sliding plug 62 upward, the gas can only flow downward. The gas reversely passes through the coalescing separation filter element 4, prompting 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 accumulates at the bottom of the coalescing separation filter element 4. At this time, the liquid deposits at the bottom of the coalescing separation filter element 4 and is more likely to aggregate 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 decreases. At this time, the resistance of the gas in the housing 1 passing through the coalescing separation filter element 4 decreases, and the gas in the housing 1 passes through the coalescing separation filter element 4 upward again, squeezing the sliding plug 62 to move upward. The first spring on the sliding plug 62 compresses and stores energy again. The movement of the sliding plug 62 no longer squeezes the extrusion block 73. The extrusion block 73, the sliding rod 72, and the control valve 71 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 coalescing separation filter element 4 is automatically backflushed and cleaned when the liquid content in the adjacent coalescing separation filter element 4 is high, so that the separation accuracy of the coalescing separation filter element 4 is always maintained at a high level, thereby improving the overall separation performance of the device.

[0026] After all the materials are separated, the staff cleans the inside of the housing 1 and discharges the waste liquid after cleaning in the housing 1 through the second discharge pipe 102. Subsequently, 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, at this time, the flow path of the light liquid is the same as the flow path of the gas in the above 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 gas-liquid separation process. The backflush pipe 7 no longer sprays gas but directly sprays the light liquid, and the device separates the two liquids according to the same principle as above.

[0027] Further, referring to Figure 2 and Figures 9-11, the plugging mechanism includes a second mounting bracket 10, the second mounting bracket 10 is fixedly connected to the housing 1, the second mounting bracket 10 is fixedly connected with a fixed disk 11, the fixed disk 11 is slidably connected with a sliding seal 12, the sliding seal 12 is used to detect the height of the liquid level, a liquid storage cavity 121 is arranged in the sliding seal 12, an adjusting component is arranged in the sliding seal 12, and 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 housing 1.

[0028] Furthermore, referring to Figures 10-12 , the adjusting component includes an air inlet pipe 13, the air inlet pipe 13 is fixedly connected to the sliding seal 12, and the air inlet pipe 13 is communicated with the liquid storage cavity 121. The sliding seal 12 is fixedly connected with a return air pipe 131, a liquid inlet pipe 14 and a liquid return pipe 141. The return air pipe 131, the liquid inlet pipe 14 and the liquid return pipe 141 are all communicated with the liquid storage cavity 121. Ball valves are installed on the air inlet pipe 13, the return air pipe 131, the liquid inlet pipe 14 and the liquid return pipe 141. A control component is arranged on the sliding seal 12, and the control component is used to control the opening and closing of the ball valves on the air inlet pipe 13, the return air pipe 131, the liquid inlet pipe 14 and the liquid return pipe 141.

[0029] In the above content, when performing gas-liquid separation (or liquid-liquid separation), the content of liquid (or heavy liquid) in the material is unstable. Therefore, the efficiency of the automatic balance valve 103 in discharging the liquid (or heavy liquid) is uncertain. The blocking mechanism is designed to discharge the liquid (or heavy liquid) from the housing 1 while preventing the liquid (or heavy liquid) from being discharged completely in a short time, which may cause gas (or light liquid) to enter the automatic balance valve 103. The lower part of the sliding seal 12 is spherical. The automatic balance 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 balance valve 103 detects the floating height of the sliding seal 12 through mechanical transmission (since the automatic balance valve 103 is an existing device, neither the automatic balance valve 103 nor its internal components are shown in detail in the figure) to judge the liquid level height of the liquid (or heavy liquid). The inlet pipe 13 and the return pipe 131 are located on the upper side of the liquid storage chamber 121. The connection points of the inlet liquid pipe 14 and the return liquid pipe 141 with the liquid storage chamber 121 are located on the lower side of the liquid storage chamber 121. The density of the liquid discharged into the liquid storage chamber 121 by the inlet liquid pipe 14 is greater than the density of the heavy liquid (since 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 needs to be discharged into the liquid storage chamber 121 only during liquid-liquid separation) to increase the specific gravity of the sliding seal 12, so as to adjust the specific gravity of the sliding seal 12 to be slightly less than the specific gravity of the heavy liquid. When the liquid level of the liquid (or heavy liquid) at the bottom of the device reaches a certain height (this height value can be adjusted manually), the sliding seal 12 rises under the buoyancy of the liquid (or heavy liquid), and the automatic balance valve 103 opens to facilitate the discharge of the liquid (or heavy liquid). When the liquid level of the liquid (or heavy liquid) drops to a certain height, the automatic balance valve 103 closes to prevent gas (or light liquid) from being discharged outward through the automatic balance valve 103, and operates reciprocally to discharge the liquid (or heavy liquid) from the housing 1.

[0030] Furthermore, referring to Figures 11-13 , the control component includes a first gear 132, which is fixedly connected to the valve stem of the ball valve on the inlet 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 inlet pipe 13. The valve stem of the ball valve on the return liquid pipe 141 is installed with a transmission gear meshing with the first gear 132. The valve stem of the ball valve on the inlet liquid pipe 14 is fixedly connected to a second gear 142. The sliding seal 12 is fixedly connected with two third mounting brackets 15. The third mounting bracket 15 is slidably connected with a sliding member 16, and a third spring is installed between them. A rack is arranged on the sliding member 16. The first gear 132 and the second gear 142 are respectively meshed with the racks on the adjacent sliding members 16. The sliding member 16 is slidably connected with a sliding block 17. The fixed disk 11 is fixedly connected with two electromagnets 18. The electromagnets 18 and the adjacent sliding blocks 17 are magnetically attracted to each other. A control component for closing the adjacent electromagnets 18 is arranged on the sliding block 17.

[0031] Furthermore, referring to Figure 13 and Figure 14 , the regulating component includes symmetrically distributed micro-touch switches 19, and the symmetrically distributed micro-touch switches 19 are fixedly connected to adjacent sliding blocks 17. Symmetrically distributed fourth springs are installed between the sliding member 16 and the adjacent sliding blocks 17. The sliding member 16 is fixedly connected with symmetrically distributed bumps 191, and the bumps 191 are used to squeeze and trigger the micro-touch switches 19.

[0032] 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, they come into contact with each other, and the contact surface between the sliding block 17 and the adjacent electromagnet 18 is a friction surface, and it is difficult for them to move relatively up and down after magnetic attraction; initially, the ball valve on the return air pipe 131 is in the open state, and the ball valve on the intake air pipe 13 is in the closed state. The valve stems of the ball valves on both are fixedly connected. Therefore, when the ball valve on the intake air pipe 13 is opened, the ball valve on the return air pipe 131 simultaneously enters the closed state. Initially, the ball valves on the liquid inlet pipe 14 and the liquid return pipe 141 are also in the closed state. When the first gear 132 drives the ball valve on the intake air pipe 13 to rotate and open, the first gear 132 drives the transmission gear on the valve stem of the ball valve on the liquid return pipe 141 to rotate, so that the ball valve on the liquid return pipe 141 rotates and opens synchronously; the intake air pipe 13 is communicated with an external air supply system, the return air pipe 131 is communicated with the outside, the liquid inlet pipe 14 and the liquid return pipe 141 are communicated with an external liquid supply system. The air supply system and the liquid supply system are both prior arts. An exhaust device is installed in the liquid supply system to discharge the mixed gas in the liquid supply system. Among them, the liquid inlet pipe 14 is used to fill the liquid into the liquid storage cavity 121, and the liquid return pipe 141 is used to discharge the liquid in the liquid storage cavity 121. Check valves are provided in both the return air pipe 131 and the liquid return pipe 141. The return air pipe 131 can only allow the gas in the liquid storage cavity 121 to flow outwards, and the liquid return pipe 141 can only allow the gas and liquid in the liquid storage cavity 121 to flow outwards.

[0033] The working process is as follows: When the staff is ready to carry out gas-liquid separation, first start the gas supply system and the liquid supply system through the control terminal. Subsequently, start the electromagnet 18 near the intake pipe 13. The electromagnet 18 is magnetized to attract the slider 17 near the intake pipe 13. The slider 17 drives the sliding member 16 to slide, and the third spring on the sliding member 16 is compressed to store energy. The sliding member 16 drives the first gear 132 to rotate through the rack on it. The first gear 132 drives the transmission gear of the ball valve on the liquid return pipe 141 to rotate. At this time, the ball valves on the intake pipe 13 and the liquid return pipe 141 are opened, and the ball valve on the gas return pipe 131 is closed. The gas in the gas supply system rushes into the liquid storage cavity 121 through the intake pipe 13. Because the gas return pipe 131 is closed, the gas cannot be discharged outward from the gas return pipe 131. The residual liquid in the liquid storage cavity 121 is pushed by the gas and discharged into the liquid supply system through the liquid return pipe 141. When the liquid in the liquid storage cavity 121 is completely discharged, part of the gas in the liquid storage cavity 121 enters the liquid supply system through the liquid return pipe 141 and is discharged outward by the exhaust device in the liquid supply system. When the liquid storage cavity 121 is completely filled with air, the control terminal closes the electromagnet 18. The sliding member 16 moves leftward and resets under the action of the third spring. The ball valves on the intake pipe 13, the gas return pipe 131, and the liquid return pipe 141 all return to the initial state. The specific gravity of the sliding seal 12 is less than that of the liquid, so it will float on the liquid surface. At this time, the staff carries out gas-liquid separation work according to the above content. When the liquid level drops and the floating height of the sliding seal 12 is lower than a certain height, the automatic balance valve 103 automatically closes. When the liquid level reaches a certain height, the sliding seal 12 floats upward under the action of the liquid buoyancy, and the automatic balance valve 103 automatically opens. At this time, the liquid is discharged outward through the automatic balance valve 103.

[0034] When the staff is ready to perform liquid-liquid separation, the staff activates the electromagnet 18 near the liquid inlet pipe 14. The electromagnet 18 is magnetized to attract the slider 16 and the sliding block 17 near the liquid inlet pipe 14 to move. The third spring on the slider 16 is compressed and stores energy, causing the ball valve on the liquid inlet pipe 14 to open. At this time, the liquid supply system supplies liquid into the liquid storage chamber 121 through the liquid inlet pipe 14, and the gas in the liquid storage chamber 121 is discharged outward through the gas 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 slider 16 and the sliding block 17 move and reset under the action of the adjacent third spring on the slider 16, 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. Subsequently, the staff activates this device to perform liquid-liquid separation work. After the liquid-liquid separation is carried out for a certain period of time, the heavy liquid cannot make the sliding seal 12 float, and the automatic balance valve 103 is always in the closed state. Therefore, the heavy liquid accumulates at the bottom of the housing 1. Subsequently, the staff activates the electromagnet 18 near the gas inlet pipe 13, and the ball valve on the gas inlet pipe 13 opens. The gas supply system supplies gas into the liquid storage chamber 121 in the same manner as above. 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 extrusion of the gas. The specific gravity of the sliding seal 12 gradually decreases. When the specific gravity of the sliding seal 12 decreases to be less than that 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 slider 16 to move upward through the third mounting bracket 15. The fourth spring on the upper side of the slider 16 is compressed and stores energy, and the fourth spring on the lower side of the slider 16 is stretched and stores energy. The slider 16 drives the convex block 191 to move into contact with the upper microswitch 19. The microswitch 19 transmits a signal to the control terminal, and the control terminal closes the electromagnet 18 near the gas inlet pipe 13. The sliding block 17 and the slider 16 move and reset under the action of the third spring and the fourth spring on the adjacent slider 16. At this time, since the ball valve on the gas inlet pipe 13 is closed, no new gas enters the liquid storage chamber 121. Therefore, the specific gravity of the sliding seal 12 is only slightly less than that of the heavy liquid, increasing the difference between the specific gravity of the sliding seal 12 and the specific gravity of the light liquid, and reducing the probability of the light liquid entering the automatic balance valve 103.

[0035] When 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 gas supply system are closed.

[0036] Furthermore, referring to Figures 4-6 and Figure 8 , it also includes sponges 8 distributed at intervals. The number of sponges 8 is the same as and corresponds one-to-one with the number of coalescence separation filters 4. The sponges 8 are fixedly connected to the upper sides of the adjacent coalescence separation filters 4.

[0037] Furthermore, referring toFigure 8 , there are through holes in the horizontal direction in the sponge 8. An extrusion member 81 is fixedly connected to the upper side of the sponge 8. A tension spring is fixedly connected between the extrusion member 81 and the adjacent flow guide cover 6. An extrusion column 82 is fixedly connected to the sliding plug 62, and the extrusion column 82 is in extrusion contact with the extrusion member 81.

[0038] In the above solution, the sponge 8 is used to adjust the resistance of gas flow. When the gas in the backflush pipe 7 flows downward, because there is resistance when the gas penetrates the sponge 8, it promotes the gas to disperse on the upper side of the sponge 8, and then makes the gas penetrate from the upper side of the sponge 8 to the lower side of the sponge 8 in a uniform penetration manner. Furthermore, the gas flowing downward in the coalescing and separating filter element 4 is more uniform, increasing the coverage area when the gas backflushes the coalescing and separating filter element 4. By providing through holes in the horizontal direction on the sponge 8, the resistance when the gas passes through the sponge 8 is adjusted. The state of the sponge 8 when it is compressed is as shown in Figure 5 and Figure 6 shown, the state of the sponge 8 when it is not compressed is as shown in Figure 8 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 state of storing energy.

[0039] The working process is as follows: When the liquid content in the coalescing and separating filter element 4 is small and the gas squeezes the sliding plug 62 to move upward, the sliding plug 62 is separated from the flow guide cover 6. At this time, the extrusion force between the extrusion column 82 on the sliding plug 62 and the extrusion member 81 is lost, and the extrusion column 82 moves upward following the sliding plug 62. The extrusion member 81 moves upward synchronously under the action of its tension spring, and the extrusion member 81 drives the sponge 8 to stretch to the state shown in Figure 8 shown. At this time, the kinetic energy loss of the gas passing through the sponge 8 is small. When the liquid content in the coalescing and separating filter element 4 is large and the gas no longer flows upward through this coalescing and separating filter element 4, the sliding plug 62 moves downward to reset under the action of its first spring. The sliding plug 62 squeezes the extrusion member 81 to move downward through the extrusion column 82. The tension spring on the extrusion member 81 stretches and stores energy, and the extrusion member 81 drives the sponge 8 to contract downward, causing the through holes on the sponge 8 to gradually disappear (as shown in Figure 5 and Figure 6 shown), thereby increasing the resistance of the gas passing through the sponge 8 and increasing the uniformity of the gas flowing downward through the sponge 8 in the backflush pipe 7.

[0040] Furthermore, referring to Figure 2 , Figure 3 and Figure 6 , it further includes pneumatic telescopic rods 9 distributed at intervals. The number of pneumatic telescopic rods 9 is the same as and corresponds one by one to the number of flow guide covers 6. The pneumatic telescopic rods 9 are fixedly connected to the adjacent first mounting frames 61, and the telescopic ends of the pneumatic telescopic rods 9 are fixedly connected to the adjacent sliding plugs 62. All the pneumatic telescopic rods 9 on the same fixed column 5 are interconnected.

[0041] In the above solution, usually, the liquid content in the flowing gas in different diversion holes 31 is different, resulting in different liquid contents retained in different coalescing and separating filters 4. As the coalescing and separating filter 4 is used, the liquid content in each coalescing and separating filter 4 shows a gradually increasing trend. Therefore, most of the coalescing and separating filters 4 will trigger the above-mentioned process of backwashing the coalescing and separating filter 4, resulting in a large gas fluctuation in the remaining coalescing and separating filters 4, affecting the smoothness of the filtration process of this device. The above solution aims to propose a solution for cleaning different coalescing and separating filters 4 in order from the one with more retained liquid to the one with less retained liquid according to the liquid content retained in different coalescing and separating filters 4, so as to maintain the smooth operation of this 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 (the number of pneumatic telescopic rods 9 in a group in this solution is three). Only the gas with the capacity of one pneumatic telescopic rod 9 exists in each group of pneumatic telescopic rods 9. Therefore, at the same time, only the telescopic end of one pneumatic telescopic rod 9 can extend to the longest state.

[0042] The working process is as follows: Taking all the pneumatic telescopic rods 9 on a fixed column 5, i.e., adjacent components (i.e., the pneumatic telescopic rods 9 in the same group) as an example. In the initial state, the gas flow resistance in the three diversion holes 31 is similar, and the forces pushing the three sliding plugs 62 are equal. Therefore, at this time, the extended distances of the telescopic ends of the three pneumatic telescopic rods 9 are equal. When the liquid content in one of the coalescing separation filters 4 increases, the gas flow resistance in this diversion hole 31 increases, the gas volume in this diversion hole 31 decreases, and the gas volumes in the other two diversion holes 31 increase. Therefore, the gas thrust received by the sliding plug 62 at the diversion hole 31 with reduced gas volume decreases, and the gas thrusts received by the other two sliding plugs 62 increase. The other two sliding plugs 62 respectively drive the telescopic ends of the adjacent two pneumatic telescopic rods 9 to retract, squeezing all the gas into the pneumatic telescopic rod 9 at the diversion hole 31 with reduced gas volume. The telescopic end of this pneumatic telescopic rod 9 extends downward, and the sliding plug 62 at this position moves downward, triggering the adjacent backflush pipe 7 to backflush this coalescing separation filter 4. When the liquid content at this coalescing separation filter 4 decreases, the resistance of the gas passing through this coalescing separation filter 4 decreases to be less than the resistance at the other two coalescing separation filters 4. At this time, the gas pushes the sliding plug 62 and the adjacent components to move back to the original position. When there are differences in the liquid content in the other two coalescing separation filters 4, the device flushes the coalescing separation filter 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 coalescing separation filter 4 is less than the spring force on the sliding plug 62 to perform the backflush treatment on this coalescing separation filter 4. Thus, the smoothness of gas separation by the device is increased, and the probability of air flow fluctuations in the other coalescing separation filters 4 when multiple coalescing separation filters 4 are backflushed simultaneously is reduced. When all the materials are separated, there is no gas flow in all the diversion holes 31. At this time, all the sliding plugs 62 move to the same height under the elastic force of the adjacent first springs respectively, and the telescopic ends of all the pneumatic telescopic rods 9 extend to the same length.
