Description

Technical Field

[0001] The present invention relates to the technical field of the assembly of separation components of a gas-liquid separator, and particularly relates to an assembly method for a condensation vane unit. Background Art

[0002] In a natural gas transmission and distribution system, a gas-liquid separator is usually used to remove substances such as moisture and high dew-point hydrocarbons in the gas. Its key component is a metal gas-liquid separation component. The metal gas-liquid separation component divides the gas path, enabling the gas to fully contact the metal surface. Utilizing the high thermal conductivity of the metal, water vapor and liquid droplets in the gas are easily condensed or attached to the metal surface. The converged liquid sinks to the liquid accumulation pocket under the action of gravity, achieving the effect of gas-liquid separation.

[0003] Currently, the design and manufacturing method of a plate-type gas-liquid separation component is as follows: calculate the required metal area according to the processing capacity of the separator, design the number of stainless steel plates and the area of a single plate in combination with the size of the separator cylinder body, fold and press the whole stainless steel plate into a wavy shape, and finally stack and weld multiple wavy stainless steel plates into a component and install it in the cylinder body. However:

[0004] 1. Due to the large area of a single plate, it is difficult to ensure its size, angle, flatness, etc. during the repeated folding and pressing process, increasing the manufacturing difficulty of the component; both folding and pressing and assembly require larger machinery, the process is complex, and the manufacturing cost is high.

[0005] 2. After folding, pressing, and stacking, the deformation error is large, and the shape of the component cannot completely match the separator cylinder body; when stacking and welding, a gap needs to be left between every two adjacent steel plates and they cannot support each other. Therefore, the steel plates are prone to move during assembly, resulting in great difficulty and inaccurate positioning, further increasing the size error; thus, there are multiple large gaps between the component and the side wall of the cylinder body. The resistance at the gaps is less than that inside the component, causing more gas to flow directly through the gaps without passing through the separation component, resulting in a reduction in the actual separation effect.

[0006] 3. Each time, only one plate can be positioned and welded, and then the next plate is added after welding is completed, resulting in low assembly efficiency and high labor cost. Summary of the Invention

[0007] The technical problem to be solved by the present invention is: how to reduce the manufacturing difficulty and cost of the plate-type gas-liquid separation component, and improve the dimensional accuracy and assembly efficiency.

[0008] The technical solution of the present invention for solving the above technical problems is as follows:

[0009] The present invention provides an assembly method for a condensation vane unit, including the following steps:

[0010] A. Place a hoop into the vane assembly tooling;

[0011] The blade assembly tooling includes a base, on which an assembly groove is provided, and the hoop is located in the assembly groove;

[0012] B. Insert multiple blade plates into the hoop. The edges of the blade plates contact the inner wall of the hoop. The multiple blade plates are arranged at intervals, and both sides of the blade plates are positioned by positioning blocks;

[0013] The positioning blocks are arranged vertically and fixed to the bottom of the assembly groove;

[0014] C. Sleeve another hoop from the upper part of the blade plate, and weld and fix the hoop and the blade plate to form a condensing blade unit.

[0015] The beneficial effects of the present invention are as follows:

[0016] Adopting the present invention, 1. Through the assembly groove and the positioning blocks, the hoop and the blade plates are positioned simultaneously, keeping the blade plates in a vertical state, reducing the welding difficulty and improving the positioning accuracy; 2. The blade plates are all constrained within the hoop, and the forming accuracy of the condensing blade unit is high. Multiple condensing blade units can be assembled into a relatively large gas-liquid separation assembly, which is convenient and efficient to assemble, has a small dimensional error, can be perfectly matched with the separator cylinder body, and improves the gas-liquid separation effect; 3. The area of a single plate required for manufacturing is small, the processing difficulty is small, the deformation accuracy is high, large machinery is eliminated, and the cost is low; 4. After multiple blades are positioned, they are welded to the hoop uniformly, reducing the cross-time consumption of group welding and lowering the labor-hour cost.

[0017] On the basis of the above technical solution, the present invention can be further improved as follows.

[0018] Further, in step A, the upper end of the hoop is higher than the assembly groove.

[0019] Avoiding the arc or molten iron of the blade plate welding from fixing the hoop in the assembly groove is convenient for welding the blade plate and taking out the condensing blade unit after welding, with good reliability.

[0020] Further, step B further includes: inserting two blade side plates into the hoop. The blade plates are both located between the two blade side plates. One side of the blade side plate contacts the positioning block, and the other side of the blade side plate contacts the inner wall of the hoop; step C further includes: welding and fixing the blade side plate and the hoop.

[0021] The welding area between the blade side plate and the hoop is large, improving the overall strength; at the same time, when multiple condensing blade units are assembled into a relatively large gas-liquid separation assembly, the gap outside the condensing blade unit is reduced, avoiding the excessive gap between adjacent two condensing blade units during assembly from affecting the separation effect; using one positioning block to position the blade side plate with the inner wall of the hoop is convenient for clamping and constraining the blade side plate, avoiding the sliding and swinging of the blade side plate.

[0022] Further, the positioning blocks on both sides of each blade plate are arranged oppositely, and a gap capable of clamping the blade plate is formed between the two positioning blocks.

[0023] By clamping a blade plate between every two positioning blocks, the sliding and swinging of the blade plate are avoided, the stability is good, and the forming precision of the condensing blade unit is improved; moreover, the number of positioning blocks required is the least, and the cost is low.

[0024] Further, in step C, the operation of sleeving other hoop rings from the upper part of the blade plate is specifically as follows: two hoop rings are sleeved from the upper part of the blade plate, one hoop ring is sleeved in the middle of the blade plate and the blade side plate, and the other hoop ring is sleeved at the upper ends of the blade plate and the blade side plate.

[0025] The overall strength of the condensing blade unit is improved, the separation of the blade plate and the hoop ring during loading is avoided, and the deformation amount of the blade plate is reduced, ensuring the separation effect.

[0026] Further, the upper ends of the blade plate and the blade side plate are flush with the upper end of the first hoop ring above.

[0027] Both ends of the blade plate and the blade side plate do not protrude from the hoop ring. When the condensing blade unit or the gas-liquid separation assembly is spliced axially, it prevents the direct contact between the ends of the blade plate and the blade side plate and the outside world, resulting in stress concentration, and avoids structural damage, with good reliability.

[0028] Further, the shapes of the hoop rings are the same, and the shape of the hoop ring is the same as the shape of the assembly groove.

[0029] The hoop ring is completely attached to the inner side wall of the assembly groove, avoiding the deformation of the hoop ring affected by the welding stress, and having high forming precision.

[0030] Further, the hoop ring is a polygon that can be closely paved, and the orientation of each hoop ring is the same.

[0031] It is convenient to use a plurality of exactly the same condensing blade units to form a larger gas-liquid separation assembly. The condensing blade unit can be manufactured in batches according to the present invention, with high production efficiency.

[0032] Further, the hoop ring is a regular hexagon.

[0033] It is convenient to assemble the regular hexagon condensing blade unit. The regular hexagon condensing blade unit can form a gas-liquid separation assembly with a honeycomb cross-section, which is convenient for cutting the air duct, with uniform air flow and good gas-liquid separation effect.

[0034] Further, the base includes a bottom plate and an assembly cylinder body. The assembly cylinder body is fixed on the bottom plate, and the inner side wall of the assembly cylinder body forms the inner side wall of the assembly groove.

[0035] The bottom plate and the assembled cylinder can be separately formed and then assembled, which is convenient for processing and has a low manufacturing cost. Brief Description of the Drawings

[0043] 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 intended to limit the scope of the present invention.

[0044] Refer to the present invention Figures 1-5 .

[0045] The present invention provides an assembly method for a condensation blade unit, including the following steps:

[0046] A. Place a hoop ring 4 into the blade assembly tooling;

[0047] The blade assembly tooling includes a base 1, an assembly groove 2 is provided on the base 1, and the hoop ring 4 is located in the assembly groove 2;

[0048] Note: This step is as Figure 1 shown.

[0049] B. Insert multiple blade plates 7 into the hoop ring 4, the edges of the blade plates 7 contact the inner wall of the hoop ring 4, the multiple blade plates 7 are arranged at intervals, and both sides of the blade plates 7 are positioned by positioning blocks 3;

[0050] The positioning blocks 3 are arranged vertically and fixed at the bottom of the assembly groove 2;

[0051] Note: This step is as Figure 2 shown.

[0052] C. Insert other hoop rings 4 from the upper part of the blade plate 7, and weld and fix the hoop ring 4 to the blade plate 7 to form a condensing blade unit.

[0053] Note: This step is as Figure 3 , 4 shown.

[0054] Principle:

[0055] After step C, the condensing blade unit can be taken out from the blade assembly tooling. A single condensing blade unit can be used as a small-volume gas-liquid separation component to match the separator cylinder body. Multiple condensing blade units can also be arranged in parallel. The two ends of each condensing blade unit are flush, and the side surfaces of the hoop rings 4 of every two adjacent condensing blade units are in contact with each other to form a large-volume gas-liquid separation component to match the separator cylinder body with a larger diameter. The assembly methods include but are not limited to the following:

[0056] 1. External assembly outside the cylinder body. Fix every two adjacent condensing blade units by spot welding to form an integral gas-liquid separation component. Install the integral gas-liquid separation component into the cylinder body, assemble the inlet and outlet nozzles at both ends of the cylinder body, and connect the liquid accumulation package at the lowest position on the side wall of the cylinder body to form a gas-liquid separator. One or more gas-liquid separation components can be installed along the axial direction of the cylinder body, and the specific quantity is determined according to actual requirements.

[0057] 2. Internal assembly inside the cylinder body. Put multiple condensing blade units into the cylinder body one by one, and the arrangement mode of the condensing blade units remains unchanged. During maintenance, each condensing blade unit can be replaced separately.

[0058] By adopting the present invention, 1. Through the assembly groove 2 and the positioning block 3, the hoop ring 4 and the blade plate 7 are positioned simultaneously, keeping the blade plate 7 in an upright state, reducing the welding difficulty and improving the positioning accuracy; 2. The blade plates 7 are all constrained within the hoop ring 4, and the forming accuracy of the condensing blade unit is high. Multiple condensing blade units can be formed into a large-volume gas-liquid separation component, which is convenient and efficient to assemble, has small dimensional errors, can be perfectly matched with the separator cylinder body, and improves the gas-liquid separation effect; 3. The area of a single sheet required for manufacturing is small, the processing difficulty is small, the deformation accuracy is high, large machinery is omitted, and the cost is low; 4. After multiple blades are positioned, they are welded to the hoop ring 4 uniformly, reducing the cross-time consumption of group welding and lowering the man-hour cost.

[0059] Further, in step A, the upper end of the hoop ring 4 is higher than the assembly groove 2.

[0060] Avoid the electric arc or molten iron of the welding of the blade plate 7 from fixing the hoop ring 4 in the assembly groove 2, which is convenient for welding the blade plate 7 and taking out the condensing blade unit after welding, and has good reliability.

[0061] Further, step B further includes: inserting two blade side plates 8 into the hoop 4, with the blade plates 7 located between the two blade side plates 8. One side of the blade side plate 8 contacts the positioning block 3, and the other side contacts the inner wall of the hoop 4. Step C further includes: welding and fixing the blade side plate 8 to the hoop 4.

[0062] The welding area between the blade side plate 8 and the hoop 4 is large, improving the overall strength. At the same time, when multiple condensation blade units are assembled into a larger gas-liquid separation component, the gap outside the condensation blade unit is reduced, avoiding excessive gaps between adjacent two condensation blade units during assembly and affecting the separation effect. Using one positioning block 3 and the inner wall of the hoop 4 to position the blade side plate 8 facilitates the clamping and restraint of the blade side plate 8, avoiding sliding and swinging of the blade side plate 8.

[0063] Further, the positioning blocks 3 on both sides of each blade plate 7 are arranged oppositely, and a gap for clamping the blade plate 7 is formed between the two positioning blocks 3.

[0064] By clamping one blade plate 7 between every two positioning blocks 3, sliding and swinging of the blade plate 7 are avoided, with good stability and improved forming accuracy of the condensation blade unit. Moreover, the number of required positioning blocks 3 is the least, and the cost is low.

[0065] Further, in step C, the operation of sleeving other hoops 4 from the upper part of the blade plate 7 specifically means: sleeving two hoops 4 from the upper part of the blade plate 7, where one hoop 4 is sleeved in the middle of the blade plate 7 and the blade side plate 8, and the other hoop 4 is sleeved at the upper end of the blade plate 7 and the blade side plate 8.

[0066] It improves the overall strength of the condensation blade unit, prevents the blade plate 7 from detaching from the hoop 4 when bearing weight, and reduces the deformation amount of the blade plate 7, ensuring the separation effect.

[0067] Further, the upper ends of the blade plate 7 and the blade side plate 8 are flush with the upper end of the first hoop 4 above.

[0068] Both ends of the blade plate 7 and the blade side plate 8 do not protrude from the hoop 4. When the condensation blade unit or the gas-liquid separation component is axially spliced, it prevents the ends of the blade plate 7 and the blade side plate 8 from directly contacting the outside, resulting in stress concentration and avoiding structural damage, with good reliability.

[0069] Further, the hoops 4 have the same shape, and the shape of the hoop 4 is the same as the shape of the assembly groove 2.

[0070] The inner side walls of the hoop 4 and the assembly groove 2 are completely fitted, avoiding deformation of the hoop 4 due to welding stress and having high forming accuracy.

[0071] Further, the hoop 4 is a polygon that can be densely paved, and the orientation of each hoop 4 is the same.

[0072] Note: Capable of being closely paved means that multiple figures with exactly the same shape and size are joined together, and they can be paved into a whole without leaving any gaps or overlapping with each other.

[0073] It is convenient to use multiple completely identical condensation vane units to form a relatively large gas-liquid separation component. The condensation vane units can be mass-produced in a standardized manner according to the present invention, and the production efficiency is high.

[0074] Furthermore, the hoop 4 is a regular hexagon.

[0075] It is convenient to assemble the regular hexagon condensation vane units. The regular hexagon condensation vane units can form a gas-liquid separation component with a honeycomb-shaped cross-section, which is convenient for cutting the air ducts, the air flow is uniform, and the gas-liquid separation effect is good.

[0076] Furthermore, the base 1 includes a bottom plate 5 and an assembling cylinder 6. The assembling cylinder 6 is fixed on the bottom plate 5, and the inner side wall of the assembling cylinder 6 forms the inner side wall of the assembling groove 2.

[0077] The bottom plate 5 and the assembling cylinder 6 can be separately formed and then assembled, which is convenient for processing and has a low manufacturing cost.
