Description

Technical Field

[0001] The invention relates to the technical field of assembly of separation components of a gas-liquid separator, and in particular to an assembly method of a condensing blade unit. Background Art

[0002] In the natural gas transmission and distribution system, 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 component, which divides the gas path so that the gas can fully contact the metal surface. Taking advantage of the high thermal conductivity of metal, water vapor and droplets in the gas are easily condensed or attached to the metal surface, and the gathered liquid settles into the liquid accumulation bag under the action of gravity, achieving the effect of gas-liquid separation.

[0003] At present, the design and manufacturing method of plate-type gas-liquid separation components is to calculate the required metal area according to the processing capacity of the separator, design the number of layers and single area of ​​stainless steel plates in combination with the size of the separator cylinder, fold the entire stainless steel plate into a wavy shape, and finally stack and weld multiple wavy stainless steel plates into components and install them into the cylinder. However: 1. Due to the large area of ​​a single board, its size, angle, flatness, etc. are difficult to guarantee during repeated folding and pressing, which increases the difficulty of manufacturing components; folding and assembly require larger machinery, complex processes, and high manufacturing costs.

[0004] 2. After folding and stacking, the deformation error is large, and the shape of the component cannot completely match the separator cylinder; during stacking welding, a gap must be left between each two adjacent steel plates, and they cannot support each other. Therefore, the steel plates are easy to move during assembly, which makes it difficult and the positioning is inaccurate, further increasing the dimensional error; as a result, there are multiple large gaps between the component and the side wall of the cylinder, and the resistance in the gaps is smaller than that inside the component, so that more gas does not pass through the separation component, but flows directly through the gaps, resulting in a reduction in the actual separation effect.

[0005] 3. Only one plate can be positioned and welded at a time, and the next plate can be added after the welding is completed, resulting in low assembly efficiency and high labor cost. 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 plate-type gas-liquid separation component and improve dimensional accuracy and assembly efficiency.

[0007] The technical solution of the present invention to solve the above technical problems is as follows: The present invention provides an assembly method of a condensing blade unit, comprising the following steps: A. Place a hoop into the blade assembly tool; The blade assembly tool comprises a base, the base is provided with an assembly groove, and the hoop is located in the assembly groove; B. Insert multiple blade plates into the hoop, with the edges of the blade plates contacting the inner wall of the hoop, and the multiple blade plates are arranged at intervals, and both sides of the blade plates are positioned by positioning blocks; The positioning block is arranged vertically and fixed at the bottom of the assembly groove; C. Insert other hoops from the upper part of the blade plate, and weld the hoops to the blade plate to form a condensing blade unit.

[0008] The beneficial effects of the present invention are: By adopting the present invention, 1. the hoop and the blade plate are positioned at the same time through the assembly groove and the positioning block, so that the blade plate remains in an upright state, the welding difficulty is reduced, and the positioning accuracy is improved; 2. the blade plates are all constrained in the hoop, and the molding accuracy of the condensing blade unit is high. A plurality of condensing blade units can be combined into a larger gas-liquid separation component, which is convenient and efficient to assemble, with a small dimensional error, and can be fully matched with the separator cylinder, thereby improving 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 the multiple blades are positioned, they are uniformly welded to the hoop, which reduces the time consumption of cross-assembly welding and reduces the labor cost.

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

[0010] Further, in step A, the upper end of the hoop is higher than the assembly groove.

[0011] The arc or molten iron during blade plate welding is prevented from fixing the hoop in the assembly groove, which is convenient for welding the blade plate and taking out the condensing blade unit after welding, and has good reliability.

[0012] Furthermore, step B also includes: inserting two blade side plates into the hoop, the blade plates are 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 also includes: welding and fixing the blade side plate to the hoop.

[0013] The welding area between the blade side plate and the hoop is large, which improves the overall strength; at the same time, when multiple condensing blade units are assembled into a larger gas-liquid separation component, the gap on the outside of the condensing blade unit is reduced, avoiding the gap between two adjacent condensing blade units during assembly that is too large to affect the separation effect; a positioning block and the inner wall of the hoop are used to position the blade side plate, which facilitates the clamping and restraining of the blade side plate and avoids sliding and swinging of the blade side plate.

[0014] Furthermore, the positioning blocks on both sides of each blade plate are arranged relative to each other, and a gap that can be used to clamp the blade plate is formed between the two positioning blocks.

[0015] By clamping a blade plate between every two positioning blocks, sliding and swinging of the blade plate are avoided, the stability is good, and the molding accuracy of the condensing blade unit is improved; and the number of positioning blocks required is minimal, and the cost is low.

[0016] Furthermore, in step C, the other hoops are inserted from the upper part of the blade plate, specifically: two hoops are inserted from the upper part of the blade plate, one of which is inserted into the middle of the blade plate and the blade side plate, and the other hoop is inserted into the upper end of the blade plate and the blade side plate.

[0017] The overall strength of the condensing blade unit is improved to prevent the blade plate from being separated from the hoop when bearing weight, and the deformation of the blade plate is reduced to ensure the separation effect.

[0018] Furthermore, the upper end of the blade plate and the upper end of the blade side plate are flush with the upper end of the first hoop above.

[0019] Both ends of the blade plate and the blade side 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 and the blade side plate are prevented from directly contacting the outside world to cause stress concentration, thereby avoiding structural damage and improving reliability.

[0020] Furthermore, the shapes of the hoops are the same, and the shape of the hoops is the same as the shape of the assembly groove.

[0021] The hoop is completely fitted with the inner wall of the assembly groove, so that the hoop is prevented from being deformed by welding stress, and the forming accuracy is high.

[0022] Furthermore, the hoop is a closely paved polygon, and the orientation of each hoop is the same.

[0023] It is convenient to adopt a plurality of completely identical condensing blade units to form a gas-liquid separation component with a larger volume. The condensing blade units can be manufactured in standardized batches according to the present invention, and the production efficiency is high.

[0024] Furthermore, the hoop is a regular hexagon.

[0025] It is convenient to assemble the regular hexagonal condensing blade units, which can form a gas-liquid separation component with a honeycomb cross-section, which is convenient for cutting the airway, has uniform airflow and good gas-liquid separation effect.

[0026] Furthermore, the base includes a bottom plate and an assembling cylinder, the assembling cylinder is fixed to the bottom plate, and the inner side wall of the assembling cylinder forms the inner side wall of the assembling groove.

[0027] The bottom plate and the assembly cylinder can be assembled after being formed separately, which is convenient for processing and has low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present invention refers to Figure 1-5 .

[0036] The present invention provides an assembly method of a condensing blade unit, comprising the following steps: A.

[0037] B. Insert the plurality of blade plates 7 into the hoop 4, with the edges of the blade plates 7 contacting the inner wall of the hoop 4, and the plurality of blade plates 7 are arranged at intervals, and both sides of the blade plates 7 are positioned by the positioning blocks 3; The positioning block 3 is arranged vertically and fixed at the bottom of the assembly groove 2; Note: This step is as follows Figure 2 shown.

[0038] C. Insert other hoop rings 4 from the upper part of the blade plate 7, and weld the hoop rings 4 and the blade plate 7 to form a condensing blade unit.

[0039] Note: This step is as follows Figure 3 , 4 shown.

[0040] principle: After step C, the condensing blade unit can be taken out from the blade assembly tool. A single condensing blade unit can be used as a small-volume gas-liquid separation component to match the separator cylinder. Multiple condensing blade units can also be arranged in parallel with each other, with the two ends of each condensing blade unit flush, and the sides of the hoop ring 4 of each adjacent two condensing blade units in contact with each other, forming a larger gas-liquid separation component to match the separator cylinder with a larger diameter. Including but not limited to the following assembly methods: 1. Assemble outside the cylinder, fix each two adjacent condensing blade units by spot welding to form an integrated gas-liquid separation component. Install the gas-liquid separation component into the cylinder as a whole, assemble the air inlet and outlet pipes at both ends of the cylinder, and connect the liquid accumulation bag at the lowest position of the side wall of the cylinder to form a gas-liquid separator. One or more gas-liquid separation components can be installed along the axial direction of the cylinder, and the specific number is determined according to actual needs.

[0041] 2. Assemble in the cylinder, put 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 separately.

[0042] By adopting the present invention, 1. the hoop 4 and the blade plate 7 are positioned at the same time through the assembly groove 2 and the positioning block 3, so that the blade plate 7 remains in an upright state, the welding difficulty is reduced, and the positioning accuracy is improved; 2. the blade plates 7 are all constrained in the hoop 4, and the molding accuracy of the condensing blade unit is high. A plurality of condensing blade units can be combined into a larger gas-liquid separation component, which is convenient and efficient to assemble, with a small dimensional error, and can be fully matched with the separator cylinder, thereby improving 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 omitted, and the cost is low; 4. After the multiple blades are positioned, they are uniformly welded to the hoop 4, which reduces the time consumption of cross-welding and reduces the labor cost.

[0043] Furthermore, in step A, the upper end of the hoop 4 is higher than the assembly groove 2 .

[0044] The arc or molten iron during the welding of the blade plate 7 is prevented from fixing the hoop 4 in the assembly groove 2, so that the welding of the blade plate 7 and the removal of the condensation blade unit after welding are facilitated, and the reliability is good.

[0045] Furthermore, step B also includes: inserting two blade side plates 8 into the hoop 4, the blade plates 7 are 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 of the blade side plate 8 contacts the inner wall of the hoop 4; step C also includes: welding and fixing the blade side plate 8 to the hoop 4.

[0046] The welding area between the blade side plate 8 and the hoop 4 is large, which improves the overall strength; at the same time, when multiple condensing blade units are assembled into a larger gas-liquid separation component, the gap on the outside of the condensing blade unit is reduced, avoiding the gap between two adjacent condensing blade units during assembly that is too large to affect the separation effect; a positioning block 3 and the inner wall of the hoop 4 are used to position the blade side plate 8, which facilitates the clamping and restraining of the blade side plate 8, avoiding sliding and swinging of the blade side plate 8.

[0047] Furthermore, the positioning blocks 3 on both sides of each blade plate 7 are arranged opposite to each other, and a gap that can be used to clamp the blade plate 7 is formed between the two positioning blocks 3 .

[0048] By clamping a blade plate 7 between every two positioning blocks 3, sliding and swinging of the blade plate 7 are avoided, the stability is good, and the molding accuracy of the condensing blade unit is improved; and the number of positioning blocks 3 required is minimal, and the cost is low.

[0049] Furthermore, in step C, the other hoops 4 are inserted from the upper part of the blade plate 7, specifically: two hoops 4 are inserted from the upper part of the blade plate 7, one of the hoops 4 is inserted into the middle of the blade plate 7 and the blade side plate 8, and the other hoop 4 is inserted into the upper end of the blade plate 7 and the blade side plate 8.

[0050] The overall strength of the condensing blade unit is improved to prevent the blade plate 7 from being separated from the hoop 4 when bearing weight, and the deformation of the blade plate 7 is reduced to ensure the separation effect.

[0051] Furthermore, the upper end of the blade plate 7 and the upper end of the blade side plate 8 are both flush with the upper end of the first hoop 4 above.

[0052] Both ends of the blade plate 7 and the blade side plate 8 do not protrude from the hoop 4.

[0055] Furthermore, the hoop 4 is a closely paved polygon, and the orientation of each hoop 4 is the same.

[0056] Note: Tileable means that multiple figures of exactly the same shape and size can be joined together without leaving any gaps or overlapping.

The condensing blade units can be manufactured in standardized batches according to the present invention, and the production efficiency is high.

[0058] Furthermore, the hoop 4 is a regular hexagon.

[0059] It is convenient to assemble the regular hexagonal condensing blade units, which can form a gas-liquid separation component with a honeycomb cross-section, which is convenient for cutting the airway, has uniform airflow and good gas-liquid separation effect.

[0060] 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 .
