Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separators, in particular to a condensing blade unit. Background Art

[0002] Natural gas is susceptible to moisture infiltration during extraction, placement, transportation, and pipeline construction. Some natural gas components contain hydrocarbons with high dew points. These moisture and hydrocarbons easily condense due to temperature drops in the natural gas transmission and distribution system, impacting the operation of pressure regulating equipment, metering equipment, and instrumentation. In winter, low ambient temperatures and the resulting temperature drop in the pressure regulating system can also lead to ice blockages due to condensation of some of the medium.

[0003] In natural gas transmission and distribution systems, gas-liquid separators are usually used to remove moisture, high-dew-point hydrocarbons and other substances from the gas. The key component is the metal gas-liquid separation assembly. The metal gas-liquid separation assembly 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 easily condense or adhere to the metal surface. The gathered liquid settles into the liquid accumulation bag under the action of gravity, achieving the effect of gas-liquid separation.

[0004] At present, the metal gas-liquid separation components mainly have the following structures:

[0005] 1. Stacked corrugated plate components. Calculate the required metal area based on the processing capacity of the separator, design the number of layers and single area of stainless plates based on 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 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. As a result, there are multiple large gaps between the component and the side wall of the cylinder. The resistance in the gaps is smaller than that inside the component, causing more gas to flow directly through the gaps without passing through the separation component, thereby reducing the actual separation effect.

[0006] 2. Touch-mesh assembly. Stainless steel wire mesh is overlapped, arranged into an assembly, and then inserted into the separator cylinder. Its advantages lie in its simple structure and ease of manufacturing. However, the actual metal surface area of the wire mesh per unit volume is much smaller than that of a stacked corrugated plate assembly. At the same processing capacity, the touch-mesh assembly is larger, increasing the cost of the separator cylinder. Furthermore, the wire mesh is relatively weak and prone to localized breakage. Damaged wire mesh layers cannot be repaired after overlapping and securing. The mesh has small pores. When dust or particulate impurities are present in the gas, these solid impurities mix with liquid droplets and adhere to the wire mesh, gradually causing clogging. Consequently, the performance of touch-mesh assemblies degrades rapidly, resulting in a short service life. Utility Model Content

[0007] The technical problem to be solved by the present invention is: how to reduce the manufacturing difficulty and cost of a metal gas-liquid separation component and at the same time improve the actual separation effect.

[0008] The technical solution of the utility model to solve the above technical problems is as follows:

[0009] The utility model provides a condensing blade unit, comprising a plurality of blade plates, both ends of which are respectively provided with hoops, 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 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 within the projection of the hoop.

[0010] The beneficial effects of the utility model are:

[0011] By adopting the utility model, the area of each blade plate is small, the processing difficulty is small, and there is no need to use large machinery, which reduces the manufacturing cost; since the projection of the blade plate falls into the projection of the hoop, multiple condensing blade units can be formed into a gas-liquid separation component by closely paving the hoop, which is convenient for assembly; since the deformation error of the blade plate is small, it is easy to ensure the size, angle, flatness, etc. of the condensing blade unit, so that the gas-liquid separation component has a high degree of fit with the cylinder, thereby improving the actual separation effect.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, each hoop has the same shape, size and orientation.

[0014] During assembly, the spaces occupied by both ends of the condensing blade unit are the same, which makes it easy to control or eliminate the gap between adjacent condensing blade units and reduce assembly errors.

[0015] Furthermore, the hoop is polygonal.

[0016] There is no need to set hoops of complex shapes, which makes it easy to pave closely and to eliminate the gaps between each two adjacent condensation blade units during assembly. If it is a non-close-paved polygon, it can be paved closely by simply using hoops of different sizes and shapes to fill the gaps.

[0017] Furthermore, the hoop is in a densely paved shape.

[0018] It is convenient to adopt a plurality of identical condensing blade units to form a gas-liquid separation component, and the condensing blade units can be manufactured in standardized batches, with high production efficiency.

[0019] Furthermore, the hoop is a regular hexagon.

[0020] The gas-liquid separation component is composed of regular hexagonal condensing blade units. The cross-section of the gas-liquid separation component is honeycomb-shaped, which is convenient for cutting airways, ensuring uniform airflow and good gas-liquid separation effect. At the same time, it avoids the sharp outer corners of the hoop and improves safety.

[0021] Furthermore, the inner side wall of the hoop is connected to the edge of the blade plate, and the multiple blade plates are parallel to each other.

[0022] The side of each blade plate faces the gas flow channel, so that the blade plate can fully contact the air flow, allowing high dew point components to condense or adhere to the blade plate, thereby improving the separation effect.

[0023] Furthermore, at least one hoop is provided in the middle of the blade plate.

[0024] Improve the overall strength of the condensing blade unit to prevent the blade plate from separating from the hoop when bearing weight.

[0025] Furthermore, both ends of the blade plate are located in the hoop.

[0026] Both ends of the blade plate do not protrude from the hoop. When the condensing blade unit or the gas-liquid separation component is spliced along the axial direction, the ends of the blade plate are prevented from directly contacting the outside world to cause stress concentration, thereby avoiding structural damage and improving reliability.

[0027] 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 wavy shape.

[0028] One side of the first plate is connected to the inner wall of the hoop, and the welding area is large. Different hoops can support each other through the first plate, which improves the overall strength and reduces the gap on the outside of the condensing blade unit, avoiding a large gap between two adjacent condensing blade units during assembly; multiple pieces of the second plate are bent into a wave shape to facilitate full contact with the airflow and guide droplets.

[0029] 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.

[0030] It is convenient to increase the contact area between the first plate and the airflow, and the U-shaped cross-section of the first plate can effectively cut the airway and improve the separation effect; thereby reducing the processing difficulty of the second plate.

[0037] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] This utility model refers to Figure 1-4 .

[0039] The utility model provides a condensing blade unit, comprising a plurality of blade plates 1, wherein hoops 2 are respectively provided at both ends of the blade plates 1, one end of each blade plate 1 extends into one of the hoops 2 and is connected to the inner wall of the hoops 2, and the other end of each blade plate 1 extends into another hoops 2 and is connected to the inner wall of the hoops 2, and a gap is provided between each two adjacent blade plates 1; along the length direction of the blade plates 1, the projections of the blade plates 1 fall into the projections of the hoops 2.

[0040] principle:

[0041] A plurality of condensing blade units are arranged in parallel with each other, with both ends of the condensing blade units flush, and the sides of the hoop 2 of each two adjacent condensing blade units contacting each other, to form a gas-liquid separation component of the gas-liquid separator. The assembly methods include but are not limited to the following:

[0042] 1. Assemble outside the cylinder. Secure each adjacent condensing blade unit by spot welding to form a complete gas-liquid separation assembly. Install the entire gas-liquid separation assembly into the cylinder. Attach the inlet and outlet pipes to both ends of the cylinder. Connect the liquid accumulator to the lowest point of the cylinder's sidewall to complete the gas-liquid separator. One or more gas-liquid separation assemblies can be installed along the cylinder's axial direction; the specific number depends on actual needs.

[0043] 2. Assemble in the cylinder, place multiple condensing blade units into the cylinder one by one. The arrangement of the condensing blade units remains unchanged. During maintenance, each condensing blade unit can be replaced individually.

[0044] Preferably, the hoops 2 of all condensing blade units are closely laid in the projection along the length direction of the blade plate 1. If the condensing blade units are not of a closely laid shape, a condensing blade unit of a different shape and size can be set between every three larger condensing blade units to fill the gap, so as to achieve close laying or reduce the gap. The outer contour size of the gas-liquid separation component is basically the same as the cross-sectional size of the inner cavity of the cylinder. For the corner gap between each two adjacent condensing blade units in the outermost circle, the same shape of plate can be used to block it on the inner wall of the cylinder, or a similar shape of block can be used to fill it, so as to ensure that all gases pass through the gaps between the blade plates 1 of the condensing blade units, thereby avoiding the gas from flowing from the inlet end to the outlet end of the cylinder without passing through the separation component.

[0045] Tiling: refers to the process of joining multiple graphics together without leaving any gaps or overlapping between them.

[0046] In summary, by adopting the present invention, the area of each blade plate 1 is small, the processing difficulty is small, and there is no need to use large machinery, which reduces the manufacturing cost; since the projection of the blade plate 1 falls into the projection of the hoop 2, multiple condensation blade units can be closely laid out by the hoop 2 to form a gas-liquid separation component, which is convenient to assemble; since the deformation error of the blade plate 1 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 separation effect.

[0047] Furthermore, each hoop 2 has the same shape, size and orientation.

[0048] During assembly, the spaces occupied by both ends of the condensing blade unit are the same, which makes it easy to control or eliminate the gap between adjacent condensing blade units and reduce assembly errors.

[0049] Furthermore, the hoop 2 is polygonal.

[0050] There is no need to set a hoop 2 of complex shape, which facilitates dense paving and eliminates the gap between each adjacent condensation blade unit during assembly; if it is a non-dense polygon, it can be densely paved by simply using hoops 2 of different sizes and shapes to fill the gap.

[0051] Furthermore, the hoop 2 is in a densely paved shape.

[0052] Note: A tessellated shape refers to a shape that can be tessellated if multiple figures of exactly the same shape and size are tessellated. Such figures are tessellated shapes, such as triangles, quadrilaterals, regular hexagons, etc.

[0053] It is convenient to adopt a plurality of identical condensing blade units to form a gas-liquid separation component, and the condensing blade units can be manufactured in standardized batches, with high production efficiency.

[0054] Furthermore, the hoop 2 is a regular hexagon.

[0055] The gas-liquid separation component is composed of regular hexagonal condensing 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, the sharp outer corners of the hoop 2 are avoided, thereby improving safety.

[0056] Furthermore, the inner side wall of the hoop 2 is connected to the edge of the blade plate 1, and the multiple blade plates 1 are parallel to each other.

[0057] The side surface of each blade plate 1 faces the gas flow channel, so that the blade plate 1 can fully contact the gas flow, allowing high dew point components to condense or adhere to the blade plate 1, thereby improving the separation effect.

[0058] Furthermore, at least one hoop 2 is provided in the middle of the blade plate 1 .

[0059] The overall strength of the condensing blade unit is improved to prevent the blade plate 1 from being separated from the hoop 2 when bearing weight.

[0060] Furthermore, both ends of the blade plate 1 are located inside the hoop 2 .

[0061] Both ends of the blade plate 1 do not protrude from the hoop 2. When the condensing blade unit or the gas-liquid separation component is spliced along the axial direction, the ends of the blade plate 1 are prevented from directly contacting the outside world to cause stress concentration, thereby avoiding structural damage and improving reliability.

[0062] Furthermore, the plurality of blade plates 1 include two first plates 3, and a plurality of second plates 4 are arranged between the two first plates 3, and the first plates 3 and the second plates 4 are both rectangular; one side of the first plate 3 is welded to the inner wall of the hoop 2, and the long side of the second plate 4 is welded to the inner wall of the hoop 2; the second plate 4 is bent to form a wavy shape.

[0063] Note: When the first plate 3 and the second plate 4 are bent, the fact that the multiple blade plates 1 are parallel to each other should be understood as meaning that any two adjacent plates in the first plate 3 and the second plate 4 have at least some side faces facing each other, and the gap between the two facing side faces is uniform. In other words, each pair of adjacent plates in the multiple blade plates 1 is partially parallel at multiple locations.

[0064] One side of the first plate 3 is connected to the inner wall of the hoop 2, and the welding area is large. Different hoops 2 can support each other through the first plate 3, which improves the overall strength and reduces the gap outside the condensing blade unit. It avoids the gap between two adjacent condensing blade units being too large during assembly to affect the separation effect; multiple pieces of second plates 4 are bent into a wavy shape to facilitate full contact with the airflow and guide droplets.

[0065] Furthermore, the two long sides of the first plate 3 are bent toward the same side of the first plate 3, and one side of one of the bent parts is welded to the inner wall of the hoop 2; the two long sides of the second plate 4 are bent toward both sides of the second plate 4 respectively.

[0066] It is convenient to increase the contact area between the first plate 3 and the airflow. The U-shaped cross section of the first plate 3 can effectively cut the airway and improve the separation effect; and the processing difficulty of the second plate 4 is reduced.
