Description

Technical Field

[0001] The present invention relates to the technical field of natural gas transmission equipment, and in particular to a gas-liquid separator. Background Art

[0002] The natural gas medium is prone to moisture infiltration during the process of extraction, gas placement, transportation, pipeline construction, etc. Some natural gas components contain hydrocarbons with high dew points. These moisture and hydrocarbons are very easy to condense in the natural gas transmission and distribution system due to temperature drop, affecting the operation of pressure regulating equipment, metering equipment and instruments. In winter, the ambient temperature is low, and the pressure regulating link will also produce temperature drop after the pressure is reduced. In such cases, ice blockage may be caused by the condensation of some media.

[0003] In the natural gas transmission and distribution system, a gas-liquid separator is usually used to remove impurities such as moisture and high-dew-point hydrocarbons in the gas. The key component is the metal gas-liquid separation component. The metal gas-liquid separation component divides the gas path so that the gas can fully contact the metal surface. By utilizing the high thermal conductivity of the metal, the water vapor and liquid droplets in the metal can easily condense or adhere to the metal surface. The gathered liquid settles into the liquid accumulation bag under the action of gravity, thereby achieving the purpose of gas-liquid separation.

[0004] At present, the metal gas-liquid separation components mainly have the following structures: 1. Stacked corrugated plate components. Calculate the required metal area according to the processing capacity of the separator, design the number of layers and single area of ​​the stainless plate in combination with the size of the separator cylinder, fold the entire stainless steel plate into a corrugated shape, and finally stack and weld multiple corrugated stainless steel plates into components and load them into the cylinder. Due to the large area of ​​a single plate, its size, angle, flatness, etc. are difficult to guarantee during the repeated folding and pressing process, which increases the difficulty of component production; folding and assembly require larger machinery, with complex processes and high manufacturing costs. After folding and stacking, the deformation error is large, and the shape of the component cannot completely match the separator cylinder, so that there are multiple large gaps between the component and the side wall of the cylinder. The resistance in the gap is smaller than that inside the component, so that more gas does not pass through the separation component, but flows directly through the gap, so that the actual separation effect is weakened.

[0005] 2. Touch mesh assembly. Overlap stainless steel wire mesh, arrange it into an assembly and insert it into the separator cylinder. Its advantages are simple structure and low manufacturing difficulty. However, the actual metal surface area of ​​the wire mesh per unit volume is much smaller than that of the stacked corrugated plate assembly. Under the same processing capacity, the volume of the touch mesh assembly is larger, which increases the cost of the separator cylinder. At the same time, the strength of the wire mesh is low, and it is easy to be partially damaged. The damaged wire mesh layer cannot be repaired after overlapping and fixing; the mesh holes are small. When there are dust or particulate impurities in the gas at the same time, these solid impurities will mix with the droplets and adhere to the wire mesh, gradually causing blockage; therefore, the performance of the touch mesh assembly declines quickly and the service life is short. Summary of the invention

[0006] The technical problem to be solved by the present invention is: how to reduce the manufacturing difficulty and cost of a metal gas-liquid separator and at the same time improve the actual separation effect.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: The present invention provides a gas-liquid separator, comprising a cylinder, wherein both ends of the cylinder are provided with connecting pipes, and a plurality of gas-liquid separation components are arranged in the cylinder along its own axial direction; the gas-liquid separation components comprise a plurality of condensation blade units, wherein the plurality of condensation blade units are parallel to each other and the two ends are aligned with each other, and in the orthographic projection in the length direction of the gas-liquid separation components, the outer contours of the plurality of condensation blade units are closely laid out with each other.

[0008] The beneficial effects of the present invention are: The present invention adopts multiple condensing blade units to form a gas-liquid separation component, which is easy to assemble and avoids the use of large-area plate processing in the manufacturing process. There is no need to use large-scale machinery, which reduces the manufacturing difficulty and cost; at the same time, the deformation error is reduced. Since the gaps caused by the deformation error are much smaller than the blade spacing of the condensing blade unit, it is ensured that the airflow passes through the gas-liquid separation component, thereby improving the actual separation effect.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, both ends of the gas-liquid separation component are provided with an annular first end plate, the outer peripheral shape of the first end plate is the same as the cross-sectional shape of the cavity of the cylinder; the condensation blade unit located at the outer periphery contacts the end surface of the first end plate.

[0011] The end of the gas-liquid separation component is supported by the first end plate, so that the end face of the gas-liquid separation component is evenly stressed, thereby preventing the blades of the gas-liquid separation component from being deformed due to collision during installation and transportation; the first end plate can be fully matched with the inner cavity of the cylinder. When a large gap exists between the outer periphery of the gas-liquid separation component and the inner wall of the cylinder, the gap is closed by the first end plate, so that the gas in the gap needs to enter the gas-liquid separation component to continue to flow along the axial direction of the cylinder, thereby preventing the gas in the gap from crossing the entire gas-liquid separation component and causing some impurities to escape, thereby improving the separation effect.

[0012] Furthermore, a plurality of long connecting rods are distributed on the outer peripheral side of the gas-liquid separation component, each of which passes through the first end plates at both ends of the plurality of gas-liquid separation components, and each of which has limiters at both ends.

[0013] By connecting multiple gas-liquid separation components at the same time through a long connecting rod, the multiple gas-liquid separation components form a whole, which is convenient for one-time assembly with the cylinder body, with high assembly efficiency, high structural strength and good stability; at the same time, relative rotation or separation between the multiple gas-liquid separation components is avoided, and the reliability of gas-liquid separation is good.

[0014] Furthermore, a plurality of sleeves having the same number as the long connecting rods are distributed on the outer peripheral side of each of the gas-liquid separation components, each sleeve is sleeved on a long connecting rod, and both ends of the sleeve contact the first end plate.

[0015] When the gas-liquid separator is erected or multiple gas-liquid separation components are pressed against each other, the first end plate is supported by the sleeve, which greatly reduces the stress on the condensing blade unit, avoids deformation of the blades of the condensing blade unit, and improves the reliability of gas-liquid separation.

[0016] Furthermore, on the same gas-liquid separation component, a condensing blade unit is spaced between every two adjacent sleeves.

[0017] When there is a V-shaped corner between adjacent condensing blade units, the sleeve is located in the corner and both ends contact the first end plate, ensuring that the first end plate can completely close the corner, thereby reintroducing the gas at the corner into the condensing blade unit, and the sleeve reduces the cavity cross-sectional area of ​​the corner, thereby improving the gas-liquid separation efficiency; in addition, the sleeve can protect the long connecting rod, prevent the long connecting rod from rusting, and have a long service life.

[0018] Furthermore, a plurality of protrusions are provided on the inner side of the first end plate, the number of the protrusions is the same as the number of the sleeves, and both ends of the sleeves contact the protrusions.

[0019] When there is a V-shaped corner between adjacent condensing blade units, the corner is closed by the raised portion, thereby reducing the shielding area of ​​the first end plate on the peripheral condensing blade units, improving the uniformity of the inlet and outlet air of the gas-liquid separation component, and achieving a good gas-liquid separation effect.

[0020] Furthermore, in the longitudinal direction of the gas-liquid separation component, the area where the outer contours of the plurality of condensing blade units are closely laid out is a circular area, an annular area, a rectangular area or a rectangular annular area.

[0021] Through the above-mentioned closely-paved areas, circular, circular ring-shaped, rectangular or rectangular ring-shaped gas-liquid separation components can be formed respectively, which is convenient for adapting to the cross-sectional shapes of various gas-liquid separators and has good flexibility.

[0022] Furthermore, in the longitudinal projection of the gas-liquid separation component, the area where the outer contours of multiple condensing blade units are closely laid out is a circular area; second end plates are also provided at both ends of the gas-liquid separation component, and the condensing blade units located on the inner periphery contact the end surface of the second end plate.

[0023] The gap on the inner circumference of the annular gas-liquid separation component is closed by the second end plate, which facilitates the introduction of the gas in the gap into the gas-liquid separation component, and then allows the gas to continue to flow axially along the gas-liquid separation component, thereby preventing the gas in the gap from crossing the entire gas-liquid separation component and causing some impurities to escape, thereby improving the separation effect.

[0024] Furthermore, the end face profile of the condensing blade unit is a regular hexagon.

[0025] The gas-liquid separation component is composed of regular hexagonal condensation blade units. The cross-section of the gas-liquid separation component is honeycomb-shaped, which is convenient for cutting the airway, ensuring uniform airflow and good gas-liquid separation effect. At the same time, at the outer periphery or the inner periphery of the annular gas-liquid separation component, the corners of each two adjacent condensation blade units are evenly distributed and have a minimum depth, thereby avoiding the formation of excessive gaps between the corners and the cylinder body, which would weaken the gas-liquid separation effect.

[0026] Furthermore, the condensing blade unit includes a plurality of blade plates, and hoops are respectively provided at both ends and the middle of the blade plates, one end of each blade plate extends into one of the hoops and is connected to the inner wall of the hoop, the other end of each blade plate extends into another hoop and is connected to the inner wall of the hoop, and the middle of each blade plate is connected to the inner wall of the hoop in the middle; there is a gap between each two adjacent blade plates; along the length direction of the blade plate, the projection of the blade plate falls into the projection of the hoop; the shape, size and orientation of each hoop are the same.

[0027] Each blade plate has a small area and is easy to process, so there is no need to use large machinery, which reduces manufacturing costs. Since the projections of the blade plates fall within the projection of the hoop, multiple condensation blade units can be assembled into a gas-liquid separation component by closely paving the hoop, which makes assembly easy. Since the deformation error of the blade plates is small, it is easy to ensure the size, angle, flatness, etc. of the condensation blade unit, so that the gas-liquid separation component has a high degree of fit with the cylinder, thereby improving the actual gas-liquid separation effect.

[0028] Furthermore, the multiple blade plates include two first plates, and multiple second plates are arranged between the two first plates, and the first plates and the second plates are both rectangular; one side of the first plate is welded to the inner wall of the hoop, and the long side of the second plate is welded to the inner wall of the hoop; the second plate is bent to form a wave shape.

[0029] One side of the first plate is connected to the inner wall of the hoop, with a large welding area. Different hoops can support each other through the first plate, which improves the overall strength and reduces the gap outside the condensation blade unit. This avoids excessive gap between two adjacent condensation blade units during assembly, which affects the separation effect. Multiple pieces of the second plate are bent into a wave shape to facilitate full contact with the airflow and guide droplets.

[0030] Furthermore, the two long sides of the first plate are bent toward the same side of the first plate, and one side of one of the bent parts is welded to the inner wall of the hoop; the two long sides of the second plate are bent toward both sides of the second plate respectively.

[0031] It is convenient to increase the contact area between the first plate and the airflow; the U-shaped cross section of the first plate can effectively cut the airway and improve the separation effect; and the processing difficulty of the second plate is reduced.

DETAILED DESCRIPTION

[0048] The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0049] The present invention refers to Figure 1-15 .

[0050] The present invention provides a gas-liquid separator, comprising a cylinder 1, wherein both ends of the cylinder 1 are provided with connecting pipes 2, and a plurality of gas-liquid separation components are arranged in the cylinder 1 along its own axial direction; the gas-liquid separation components comprise a plurality of condensing blade units 3, wherein the plurality of condensing blade units 3 are parallel to each other and the two ends are aligned with each other, and in the orthographic projection in the length direction of the gas-liquid separation components, the outer contours of the plurality of condensing blade units 3 are closely laid out with each other.

[0051] principle: Close paving refers to the splicing of multiple graphics without leaving gaps or overlapping each other. Close paving only considers the design shape of the condensing blade unit 3, and does not consider the deformation error in the manufacturing process; that is, if there is a gap between adjacent condensing blade units 3, but the gap is caused by the deformation error during manufacturing, it is also considered as close paving.

[0052] During operation, natural gas enters from the connecting pipe 2 at one end of the cylinder 1, and is discharged from the connecting pipe 2 at the other end of the cylinder 1 after passing through multiple gas-liquid separation components. At this time, the gas-liquid separation component divides the gas path so that the gas can fully contact the metal blades of the condensing blade unit 3, causing impurities to condense or adhere to the surface of the metal blades. For the gathered liquid, a hole can be opened at the lowest point of the cylinder 1 to connect a liquid accumulation bag or a drain pipe and other structures for discharge, or the cylinder 1 can be opened regularly for maintenance after a certain amount of liquid has been gathered. The means of liquid discharge is irrelevant to the technical issue and will not be elaborated on. End caps are provided at both ends of the cylinder 1, and the connecting pipe 2 is provided on the end cap, which is suitable for gas-liquid separators with larger diameters; for smaller diameters, the connecting pipe 2 and the end cap can be directly made of integral forgings. Figure 1-2 In the figure, the connecting pipes 2 at both ends of the cylinder 1 are of symmetrical structure. In order to show the gas-liquid separation components inside the cylinder 1, the connecting pipe 2 at one end of the cylinder 1 is hidden, which does not affect the understanding of the overall structure.

[0053] The gas-liquid separation component is assembled by closely laying a plurality of condensing blade units 3. The manufacturing process of each condensing blade unit 3 does not require the use of large-area plate processing, and the deformation error of each condensing blade unit 3 is small. Therefore, the gap between each two adjacent condensing blade units 3 caused by the deformation error is much smaller than the blade spacing; and the gap between the outermost condensing blade unit 3 and the inner wall of the cylinder 1 caused by the deformation error is much smaller than the blade spacing. Therefore, the deformation error in the manufacturing process is not enough to affect the separation effect, and the contour shape of the gas-liquid separation component matches the shape of the cylinder 1.

[0054] The present invention adopts multiple condensing blade units 3 to form a gas-liquid separation component, which is easy to assemble and avoids the use of large-area plate processing in the manufacturing process. There is no need to use large-scale machinery, which reduces the manufacturing difficulty and cost; at the same time, the deformation error is reduced. Since the gaps caused by the deformation error are much smaller than the blade spacing of the condensing blade unit 3, it is ensured that the airflow passes through the gas-liquid separation component, thereby improving the actual separation effect.

[0055] Further, such as Figure 3-4 As shown: both ends of the gas-liquid separation component are provided with an annular first end plate 4, the outer peripheral shape of the first end plate 4 is the same as the cavity cross-sectional shape of the cylinder 1; the condensation blade unit 3 located on the outer periphery contacts the end surface of the first end plate 4.

[0056] Note: When the gas-liquid separation component and the condensing blade unit 3 are polygons of the same shape, the cylinder 1 only needs to be made into the same polygon, and the gas-liquid separation component can be completely matched with the cylinder 1 without any large gap. When the cylinder 1 is circular, since the condensing blade units 3 located on the periphery are distributed along the circular contour, there is a V-shaped corner between every two adjacent condensing blade units 3, and a large gap is formed between the corner and the inner wall of the cylinder 1.

[0057] The end of the gas-liquid separation component is supported by the first end plate 4, so that the end face of the gas-liquid separation component is evenly stressed, thereby preventing the blades of the gas-liquid separation component from being deformed due to collision during installation and transportation; the first end plate 4 can be completely matched with the inner cavity of the cylinder 1. When there is a large gap between the outer periphery of the gas-liquid separation component and the inner wall of the cylinder 1, the gap is closed by the first end plate 4, so that the gas in the gap needs to enter the gas-liquid separation component to continue to flow axially along the cylinder 1, thereby preventing the gas in the gap from crossing the entire gas-liquid separation component to cause some impurities to escape, thereby improving the separation effect.

[0058] Furthermore, a plurality of long connecting rods 6 are distributed on the outer peripheral side of the gas-liquid separation component, each of which passes through the first end plates 4 at both ends of the plurality of gas-liquid separation components, and each of which is provided with a limiter 7 at both ends.

[0059] Note: The long connecting rod 6 can be a long screw, a double-headed screw, etc. The limiting member 7 can be a nut washer, a bolt head, etc., or a weld scar between the long screw and the first end plate 4.

[0060] By simultaneously connecting a plurality of gas-liquid separation components through a long connecting rod 6, the plurality of gas-liquid separation components form a whole, which is convenient for one-time assembly with the cylinder body 1, with high assembly efficiency, high structural strength and good stability; at the same time, relative rotation or separation between the plurality of gas-liquid separation components is avoided, and the reliability of gas-liquid separation is good.

[0061] Furthermore, a plurality of sleeves 8 , the same number as the long connecting rods 6 , are distributed on the outer peripheral side of each of the gas-liquid separation components. Each sleeve 8 is sleeved on a long connecting rod 6 , and both ends of the sleeve 8 contact the first end plate 4 .

[0062] When the gas-liquid separator is erected or multiple gas-liquid separation components are pressed against each other, the sleeve 8 provides support for the first end plate 4, which greatly reduces the stress on the condensing blade unit 3, avoids deformation of the blades of the condensing blade unit 3, and improves the reliability of gas-liquid separation.

[0063] Furthermore, on the same gas-liquid separation component, a condensing blade unit 3 is spaced between every two adjacent sleeves 8 .

[0064] When there is a V-shaped corner between adjacent condensing blade units 3, the sleeve 8 is located in the corner and contacts the first end plate 4 at both ends, ensuring that the first end plate 4 can completely close the corner, thereby reintroducing the gas at the corner into the condensing blade unit 3, and the sleeve 8 reduces the cavity cross-sectional area of ​​the corner, thereby improving the gas-liquid separation efficiency; in addition, the sleeve 8 can protect the long connecting rod 6, prevent the long connecting rod 6 from rusting, and prolong the service life.

[0065] Furthermore, a plurality of protrusions 5 are provided on the inner side of the first end plate 4 , the number of the protrusions 5 is the same as the number of the sleeves 8 , and both ends of the sleeves 8 contact the protrusions 5 .

[0066] When there is a V-shaped corner between adjacent condensing blade units 3, the corner is closed by the raised portion 5, thereby reducing the shielding area of ​​the first end plate 4 on the peripheral condensing blade unit 3, improving the uniformity of the inlet and outlet air of the gas-liquid separation component, and achieving a good gas-liquid separation effect.

[0067] Further, such as Figure 5-13 As shown: in the longitudinal direction of the gas-liquid separation component, the area where the outer contours of the multiple condensing blade units 3 are closely laid out is a circular area, an annular area, a rectangular area or a rectangular annular area.

[0068] Through the above-mentioned closely-paved areas, circular, annular, rectangular or rectangular annular gas-liquid separation components can be formed respectively, which is convenient for adapting to the cross-sectional shapes of various gas-liquid separators and has good flexibility; among them, the circular gas-liquid separation component such as Figure 5-7 As shown, the annular gas-liquid separation component is as follows Figure 8-10 As shown, the rectangular gas-liquid separation component is as follows Figure 11-13 shown.

[0069] Further, such as Figure 8-10 As shown: in the longitudinal direction of the gas-liquid separation component, the area where the outer contours of multiple condensing blade units 3 are closely laid out is a circular area; a second end plate 9 is also provided at both ends of the gas-liquid separation component, and the condensing blade unit 3 located on the inner periphery contacts the end surface of the second end plate 9.

[0070] The second end plate 9 closes the gap on the inner circumference of the annular gas-liquid separation component, which facilitates the introduction of the gas in the gap into the gas-liquid separation component, and then allows the gas to continue to flow axially along the gas-liquid separation component, thereby preventing the gas in the gap from crossing the entire gas-liquid separation component and causing some impurities to escape, thereby improving the separation effect.

[0071] Further, such as Figure 14-15 As shown: the end face profile of the condensing blade unit 3 is a regular hexagon.

[0072] The gas-liquid separation component is composed of regular hexagonal condensing blade units 3, and the cross-section of the gas-liquid separation component is honeycomb-shaped, which is convenient for cutting the airway, the airflow is uniform, and the gas-liquid separation effect is good; at the same time, at the outer periphery or the inner periphery of the annular gas-liquid separation component, the corners of each two adjacent condensing blade units 3 are evenly distributed and have the minimum depth, avoiding the formation of excessive gaps between the corners and the cylinder 1 to weaken the gas-liquid separation effect.

[0073] Furthermore, the condensing blade unit 3 includes a plurality of blade plates 10, and hoops 11 are respectively provided at both ends and the middle of the blade plates 10, one end of each blade plate 10 extends into one of the hoops 11 and is connected to the inner wall of the hoop 11, the other end of each blade plate 10 extends into another hoop 11 and is connected to the inner wall of the hoop 11, and the middle of each blade plate 10 is connected to the inner wall of the hoop 11 in the middle; there is a gap between each two adjacent blade plates 10; along the length direction of the blade plate 10, the projection of the blade plate 10 falls into the projection of the hoop 11; the shape, size and orientation of each hoop 11 are the same.

[0074] Each blade plate 10 has a small area and is easy to process. There is no need to use large-scale machinery, which reduces manufacturing costs. Since the projections of the blade plates 10 fall into the projection of the hoop 11, multiple condensing blade units 3 can be densely laid out through the hoop 11 to form a gas-liquid separation component, which is easy to assemble. Since the deformation error of the blade plate 10 is small, it is easy to ensure the size, angle, flatness, etc. of the condensing blade unit 3, so that the gas-liquid separation component has a high degree of fit with the cylinder 1, thereby improving the actual gas-liquid separation effect.

[0075] Furthermore, the plurality of blade plates 10 include two first plates 12, and a plurality of second plates 13 are arranged between the two first plates 12, and the first plates 12 and the second plates 13 are both rectangular; one side of the first plate 12 is welded to the inner wall of the hoop 11, and the long side of the second plate 13 is welded to the inner wall of the hoop 11; the second plate 13 is bent to form a wave shape.

[0076] Note: When the first plate 12 and the second plate 13 are bent, the fact that the multiple blade plates 10 are parallel to each other should be understood as that at least part of the side surfaces of any two adjacent plates in the first plate 12 and the second plate 13 are facing each other, and the gap between the two facing side surfaces is uniform. That is, there are multiple parts of each adjacent two blade plates 10 that are parallel to each other.

[0077] One side of the first plate 12 is connected to the inner wall of the hoop 11, and the welding area is large. Different hoop rings 11 can support each other through the first plate 12, which improves the overall strength and reduces the gap outside the condensing blade unit 3. It avoids that the gap between two adjacent condensing blade units 3 is too large during assembly to affect the separation effect; multiple pieces of the second plate 13 are bent into a wave shape to facilitate full contact with the airflow and guide droplets.

[0078] Furthermore, the two long sides of the first plate 12 are bent toward the same side of the first plate 12 , and one side of one of the bent parts is welded to the inner wall of the hoop 11 ; the two long sides of the second plate 13 are bent toward both sides of the second plate 13 .

[0079] It is convenient to increase the contact area between the first plate 12 and the airflow. The U-shaped cross section of the first plate 12 can effectively cut the airway and improve the separation effect; and the processing difficulty of the second plate 13 is reduced.
