Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation devices, in particular to a vane type mist eliminator. Background Art

[0002] The natural gas extracted from underground contains a certain amount of moisture, which is usually in the form of extremely small mist-like liquid droplets. If these droplets cannot be effectively removed, they will accumulate in the pipeline to form large water droplets, and when the temperature drops, ice plugs will form in the pipeline, and even cause damage to some equipment. The vane type mist eliminator is a commonly used gas-liquid separation device, and improving its separation efficiency has high practical significance for the development and utilization of natural gas.

[0003] Currently, the conventional vane type mist eliminator usually adopts an integral sheet metal structure without a liquid collecting tank, resulting in the difficulty of effectively converging and discharging the collected droplets, which are easily re-entrained by the new air flow. Moreover, its flow channel is simply arranged at equal intervals by multiple groups of side-by-side corrugated plates, and the width of the entire channel remains constant. When the width of the flow channel is the same, the flow state of the air flow in the channel is relatively stable. Only in the bending area of the corrugated plate, the direction of the air flow will change to a certain extent, but this change is relatively limited and not intense enough to fully stimulate the interaction between the droplets and the air flow. Therefore, the gas-liquid separation efficiency is low and the separation effect is poor. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems in the related art to a certain extent.

[0005] To this end, an object of the utility model is to provide a vane type mist eliminator, which can not only make the collected liquid converge and discharge quickly by setting a liquid collecting tank, but also change the width of the air flow channel, accelerate the disturbance of the gas, so that the gas changes more violently when passing through the air flow channel, thereby improving the gas-liquid separation efficiency and separation effect.

[0006] To achieve the above object, the present utility model provides a vane type mist eliminator, comprising: a rectangular frame which is permeable up and down; at least one limiting plate disposed in the rectangular frame, and a plurality of abnormally-shaped holes arranged side by side and equidistantly are formed on the limiting plate; a plurality of vane mechanisms arranged side by side and equidistantly, both ends of the plurality of vane mechanisms are respectively connected to the inner wall of the rectangular frame, and the plurality of vane mechanisms are respectively inserted into the corresponding abnormally-shaped holes. An upward gas-flowing air passage in a wavy shape is formed between every two adjacent vane mechanisms, and an inverted hook-shaped liquid collecting groove is arranged at each corner in the air passage, and the opening of the liquid collecting groove faces the entering direction of the air flow; a first blocking strip, one end of the first blocking strip is fixedly connected to the inside of the rectangular frame, and the first blocking strip is fixedly connected to the adjacent vane mechanism; a second blocking strip, one end of the second blocking strip is fixedly connected to the inside of the rectangular frame, the second blocking strip is fixedly connected to the adjacent vane mechanism, and the first blocking strip and the second blocking strip are arranged near the lower opening of the rectangular frame.

[0007] In the vane type mist eliminator of the present utility model, when the gas rises at a certain speed and passes through the air passage formed by the vane mechanisms, most of the gas first flows through the liquid collecting groove. When the gas generates rotation or vortex under the guidance of the liquid collecting groove and collides with the liquid collecting groove, the disturbance of the gas will be accelerated, and gas-liquid separation will be carried out. Another part of the gas that does not pass through the liquid collecting groove or the gas that detaches from the liquid collecting groove passes through the narrow passage beside the liquid collecting groove. When the flow direction and flow rate change sharply, the disturbance of the gas will be accelerated. The liquid particles in the gas are subjected to a large centrifugal force, and under the action of the centrifugal force, gas-liquid separation is achieved. And the disturbance of the gas is accelerated multiple times, making the gas-liquid separation effect better and the separation efficiency higher.

[0008] At the same time, the liquid collecting groove centrally collects the liquid particles, enabling the trapped liquid particles to quickly converge into droplets. When the gravity of the formed droplets exceeds the resultant force of the upward buoyancy of the gas and the surface tension of the liquid, the droplets will settle and separate from the surface of the liquid collecting groove and be discharged, greatly reducing the risk of being re-entrained by the subsequent air flow and ensuring the thoroughness and stability of gas-liquid separation.

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following will further describe the solutions of the present utility model. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0027] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] The vane type mist eliminator according to the embodiment of the present utility model will be described below with reference to the accompanying drawings.

[0029] The vane type mist eliminator provided by the embodiment of the present utility model can be applied to be installed in a filter separator for separating moisture in natural gas.

[0030] As Figures 1-4 shown, the vane type mist eliminator according to the embodiment of the present utility model may include a rectangular frame 1, and the rectangular frame 1 is vertically and horizontally permeable.

[0031] At least one limiting plate 2, the limiting plate 2 is arranged in the rectangular frame 1, and a plurality of irregularly shaped holes 20 arranged side by side at equal intervals are formed on the limiting plate 2.

[0032] A plurality of vane mechanisms 3 arranged side by side at equal intervals, both ends of the plurality of vane mechanisms 3 are respectively connected to the inner wall of the rectangular frame 1, and the plurality of vane mechanisms 3 are respectively inserted into the corresponding irregularly shaped holes 20.

[0033] As a possible case, in order to further improve the stability between the vane mechanism 3 inserted into the irregularly shaped hole 20 and the limiting plate 2, the contact points between the vane mechanism 3 and the limiting plate 2 can be strengthened and fixed by spot welding.

[0034] An air flow channel (not marked in the figure) for gas to flow upward in a wavy shape is formed between every two adjacent vane mechanisms 3, and an inverted hook-shaped liquid collecting groove 3000 is arranged at each corner in the air flow channel, and the opening of the liquid collecting groove 3000 is arranged towards the entering direction of the air flow.

[0035] Among them, it can be understood that on the one hand, when the gas flows through the liquid collection tank 3000, the liquid collection tank 3000 can guide the gas to generate rotation or vortex. This rotational movement will accelerate the disturbance of the gas, which helps to separate the liquid particles in the gas by using centrifugal force. Moreover, the gas will also collide with the blade mechanism 3 in the liquid collection tank 3000. Due to the large density difference between the liquid and the gas, the gas will be more likely to change direction because of its lower density and smaller inertia and continue to flow along the new path (i.e., the narrow channel beside the liquid collection tank 3000). While the liquid, due to its higher density and larger inertia, will maintain its original direction of motion or change direction more slowly, thus separating from the gas during the collision process. At the same time, the channel width at the bend in the gas flow channel is smaller than that at the non-bend part, so that the gas accelerates when passing through these narrow areas, and along with the sharp change in the flow direction, the liquid particles in the gas are subjected to a large centrifugal force. Under the action of the centrifugal force, the separation effect and efficiency of the liquid are further improved.

[0036] On the other hand, the liquid collection tank 3000 also serves the purpose of concentrating and quickly converging the liquid particles. The liquid particles attached to the liquid collection tank 3000 gradually condense into larger droplets in the liquid collection tank 3000 due to the diffusion effect and gravity. These droplets fall naturally under the traction of gravity and are effectively discharged, greatly reducing the risk of being re-entrained by the subsequent air flow and ensuring the thoroughness and stability of the gas-liquid separation.

[0037] The first sealing bar 4, one end of the first sealing bar 4 is fixedly connected to the inside of the rectangular frame 1, and the first sealing bar 4 is fixedly connected to the adjacent blade mechanism 3. The second sealing bar 5, one end of the second sealing bar 5 is fixedly connected to the inside of the rectangular frame 1, and the second sealing bar 5 is fixedly connected to the adjacent blade mechanism 3. And the first sealing bar 4 and the second sealing bar 5 are arranged near the lower opening of the rectangular frame 1.

[0038] Among them, it can be understood that by setting the first sealing bar 4 and the second sealing bar 5 to close the space in the rectangular frame 1 except for the space occupied by the multiple blade mechanisms 3, the gas must flow strictly according to the preset gas flow channel during the flow process. This mandatory path planning makes it impossible for the gas to bypass the blade mechanism 3 and rise directly, thus ensuring that the blade mechanism 3 can fully play its role in separating gas and liquid. Moreover, the setting of the first sealing bar 4 and the second sealing bar 5 not only plays the role of closing the space but also enhances the overall structural stability of the rectangular frame 1.

[0039] Specifically, when the gas (natural gas containing liquid) rises at a certain speed and passes through the gas flow channel formed by the blade mechanism 3, most of the gas first flows through the liquid collecting tank 3000. When the gas rotates or forms a vortex under the guidance of the liquid collecting tank 3000 and collides with the liquid collecting tank 3000, the disturbance of the gas will be accelerated, and gas-liquid separation will occur. Another part of the gas that does not pass through the liquid collecting tank 3000 or the gas that detaches from the liquid collecting tank 3000 passes through the narrow channel beside the liquid collecting tank 3000. When there is a sharp change in the flow direction and flow rate, the disturbance of the gas will be accelerated, and the liquid particles in the gas will be subjected to a large centrifugal force. Under the action of the centrifugal force, gas-liquid separation occurs. By accelerating the disturbance of the gas multiple times, the gas-liquid separation effect is better and the separation efficiency is higher.

[0040] At the same time, the liquid collecting tank 3000 centrally collects the liquid particles, enabling the captured liquid particles to quickly converge into droplets. When the gravity of the formed droplets exceeds the resultant force of the upward buoyancy of the gas and the surface tension of the liquid, the droplets will settle and separate from the surface of the liquid collecting tank 3000 and be discharged, greatly reducing the risk of being re-entrained by the subsequent gas flow and ensuring the thoroughness and stability of gas-liquid separation.

[0041] To further clarify the previous embodiment, in an embodiment of the present application, as Figure 4 shown, the shaped hole 20 matches the shape of the blade mechanism 3.

[0042] It can be understood that the shaped hole 20 matches the shape of the blade mechanism 3, enabling the blade mechanism 3 to closely fit the inner wall of the shaped hole 20, playing a role in limiting the blade mechanism 3 and effectively preventing the blade mechanism 3 from shaking or shifting during the gas-liquid separation process, thereby greatly improving the stability of the blade mechanism 3.

[0043] In an embodiment of the present utility model, as Figure 1 shown, the rectangular frame 1 includes two first baffles 10 and two second baffles 11.

[0044] Among them, the two second baffles 11 are fixed between the two first baffles 10. The two second baffles 11 and the two first baffles 10 form a rectangular channel, and the length of the first baffle 10 is greater than the length of the second baffle 11. The limiting plate 2 is fixed between the two first baffles 10, and the first baffle 10 is arranged side by side with the blade mechanism 3.

[0045] Among them, it can be understood that the limiting plate 2 can be fixed between the two first baffles 10 by welding. Then, the blade mechanism 3 is inserted into the special-shaped hole 20 on the limiting plate 2. Finally, the two first baffles 10 and the two second baffles 11 can be fixed together by welding. The entire assembly process is smooth and efficient, and can be easily completed without complex tools or cumbersome steps. This design not only simplifies the installation process, reduces the operation difficulty, but also ensures the firmness and reliability of the assembled structure.

[0046] In an embodiment of the present utility model, as Figure 2 shown, the blade mechanism 3 includes a guide vane 30 and a plurality of separation vanes 31.

[0047] Among them, the guide vane 30 is arranged near the lower opening of the rectangular frame 1, and one end of the guide vane 30 is fixedly connected to the adjacent separation vane 31. The first blocking strip 4 and the second blocking strip 5 are respectively fixedly connected to the adjacent guide vane 30. The guide vane 30 and the plurality of separation vanes 31 are arranged in a wave shape from bottom to top, and both ends of the guide vane 30 and the separation vanes 31 are connected to the two second baffles 11.

[0048] Specifically, the guide vane 30 evenly distributes the incoming gas between the guide vanes 30 to form an air flow channel. The plurality of separation vanes 31 and the plurality of separation vanes 31 arranged side by side form an air flow channel. In the air flow channel, the air flow direction will change rapidly, and the liquid particles will break away due to inertia, achieving the purpose of gas-liquid separation.

[0049] To further clarify the previous embodiment, in an embodiment of the present application, the guide vane 30 and the separation vanes 31 are made of stainless steel.

[0050] Specifically, stainless steel has good processing performance and can be formed by various processes such as stamping, bending, and welding to meet the requirements of various complex shapes and specifications. Secondly, stainless steel has strong corrosion resistance and is not easy to rust in a humid environment, thereby increasing the service life of the guide vane 30 and the separation vanes 31.

[0051] In an embodiment of the present utility model, as Figure 2 shown, the guide vane 30 and the separation vanes 31 are formed by one-time sheet metal bending after sheet cutting.

[0052] Specifically, the guide vane 30 and the separation vanes 31 can be processed and formed by one-time bending. One-time bending forming reduces the processing steps and processing time, making the processing process of the guide vane 30 and the separation vanes 31 faster. For large-scale production, this can significantly improve production efficiency, save the trouble of multiple processing and positioning, reduce the error rate during the processing process, and further improve the overall processing efficiency.

[0053] In an embodiment of the present utility model, as Figure 2 and Figure 3 shown, the guide vane 30 includes a first side portion 300 and a second side portion 301.

[0054] Wherein, the first side portion 300 is arranged in parallel with the first baffle 10, one end of the second side portion 301 is connected to the first side portion 300, and the second side portion 301 is arranged obliquely.

[0055] The separation vane 31 includes a third side portion 310 and a fourth side portion 311. Wherein, one end of the fourth side portion 311 is connected to the third side portion 310, the other end of the fourth side portion 311 is connected to the fourth side portion 311 in an adjacent separation vane 31, both the third side portion 310 and the fourth side portion 311 are arranged obliquely, and the inclination directions of the third side portion 310 and the fourth side portion 311 are opposite. The inclination directions of the fourth side portions 311 in every two adjacent separation vanes 31 are opposite. The other end of the second side portion 301 is connected to the adjacent fourth side portion 311, and the inclination direction of the second side portion 301 is opposite to that of the fourth side portion 311. The third side portion 310 is at the turning point of the second side portion 301 and the fourth side portion 311 or the fourth side portion 311 and the adjacent fourth side portion 311. The second side portion 301 and the correspondingly parallel third side portion 310 or the fourth side portion 311 and the correspondingly parallel third side portion 310 respectively form a liquid collecting groove 3000.

[0056] Specifically, the inclined arrangements of the second side portion 301, the third side portion 310, and the fourth side portion 311 help to guide the gas to generate a specific flow path when flowing through the air flow channel. This flow path is beneficial to the separation of liquid particles from the gas under the action of centrifugal force, improving the gas-liquid separation efficiency. Moreover, the reasonable layout and inclination angle design of the second side portion 301, the third side portion 310, and the fourth side portion 311 help to reduce the resistance of the gas when flowing through the vanes, improving the gas flow efficiency. Among them, the reasonable layout and inclination angle of the second side portion 301, the third side portion 310, and the fourth side portion 311 can be numerically simulated by using ANSYS FLUENT fluid analysis software to optimize the structural parameters, so as to set the inclination angles of the second side portion 301, the third side portion 310, and the fourth side portion 311 according to the actual situation.

[0057] The liquid collecting groove 3000 provides a collecting area for the separated liquid and a collision area for the flowing gas, thereby improving the gas separation effect and separation efficiency.

[0058] As Figure 1 shown, the above-mentioned vane type mist eliminator further includes a fixing frame 6. The fixing frame 6 is fixed on the outer wall of the rectangular frame 1, and the fixing frame 6 is rectangular.

[0059] It can be understood that by providing the fixing frame 6 with a certain degree of scalability, its layout can be adjusted as needed to adapt to different application scenarios and requirements, making installation and assembly simpler.

[0060] In one embodiment of the present invention, Figure 1 As shown, the fixing frame 6 includes two first fixing plates 60 and two second fixing plates 61 .

[0061] The two first fixing plates 60 are fixed between the two second fixing plates 61 , and the first fixing plates 60 and the second fixing plates 61 are respectively fixed on the outer wall of the rectangular frame 1 , and a plurality of through holes are respectively formed on the first fixing plates 60 and the second fixing plates 61 .

[0062] Specifically, the through holes are provided to facilitate the use of threaded fasteners to quickly fix the first fixing plate 60 and the second fixing plate 61 to specific positions in the filter separator. This design simplifies the installation process, improves installation efficiency, and also facilitates subsequent maintenance and adjustment. The threaded fasteners can be bolts or screws.

[0063] like Figure 1 As shown, the blade-type mist collector further comprises two symmetrically arranged handles 7 , and the two handles 7 are disposed on the inner wall of the rectangular frame 1 .

[0064] Specifically, when the blade-type mist collector needs to be moved or installed to a different location, the operator can easily lift the entire blade-type mist collector through the handle 7 without the need for additional lifting equipment or the cooperation of multiple people, thereby greatly improving the handling efficiency.

[0065] In summary, the blade-type mist collector of the embodiment of the utility model, by providing a liquid collecting groove, can not only make the captured droplets quickly gather and discharge, but also change the width of the airflow channel, accelerate the disturbance of the gas, and make the gas undergo more drastic changes when passing through the airflow channel, thereby improving the gas-liquid separation efficiency and separation effect.
