Description

Technical Field

[0001] The invention belongs to the field of cooling tower structure design, and in particular relates to a panel design method capable of realizing serialization and modularization of cooling towers and a cooling tower panel prepared by the method. Background Art

[0002] With the acceleration of industrialization and the continuous growth of people's living needs, cooling towers of various structures and sizes have gradually become indispensable heat exchange equipment in industrial production and air conditioning water circulation systems in large public places. The cooling tower panel has the functions of heat insulation and sealing, and is one of the key structures of the cooling tower periphery. The single panels are generally assembled to form the overall panel structure of the cooling tower. The size and structural design of the single panel have a great impact on its production cost and installation efficiency.

[0003] However, the existing cooling tower panels still have some shortcomings in the design, production and installation process. For example, in the existing cooling tower series, the panel specifications are complex and diverse. Although panels of various sizes can meet the installation requirements of cooling towers of different sizes, the same panel is not universal enough for cooling towers of different models. Panels of different specifications may require different processes and molds during the production process, the utilization rate of raw materials is not high, and it is easy to produce a lot of waste of different sizes, low production efficiency and high cost. At the same time, panels of various specifications and models will increase the burden of inventory. In addition, cooling tower panels are generally connected by a large number of fastening bolts, which is time-consuming and labor-intensive during the installation process, and the installation efficiency is low. Therefore, there is an urgent need for a panel design method that can realize the serialization and modularization of cooling towers to solve the above problems.

[0004] It should also be noted that in recent years, the technical personnel in this field have made technical innovations in terms of structure, materials, preparation methods and their combination in response to the technical defects of cooling tower panels, and have applied for and obtained a number of inventions or invention patents. As far as the performance improvement of a single cooling tower panel is concerned, the disclosed inventions or invention patents undoubtedly have a positive effect. However, for the technical defects of cooling tower panels with complex and diverse specifications and poor generality, these inventions or invention patents are of no help. Summary of the invention

[0005] The purpose of the present invention is to provide a panel design method that can realize serialization and modularization of cooling towers, thereby overcoming the defects of the above-mentioned prior art. This purpose is achieved through the following technical solutions:

[0006] A panel design method for realizing serialization and modularization of cooling towers includes the following steps:

[0007] Step 1, determine the constraints of the design size of the cooling tower panel;

[0008] Step 2, modular optimization design of the size of the cooling tower panel;

[0009] Step 3, complete the design of the cooling tower panel connection structure.

[0010] On the basis of the above technical solutions, the present invention may adopt the following technical means to achieve the purpose of the present invention better or more specifically:

[0011] The constraint condition is H 门 ≥1400mm, W 门 ≥800mm, where H 门 Height of the inspection door panel; W 门 The width of the inspection door panel.

[0012] Furthermore, the constraint condition is H 模块化 ≤1900mm, where H 模块化 is the modular panel height.

[0013] Furthermore, the constraint condition is W 模块化 +H 框 ≤1019mm, where W 模块化 H is the width of the modular panel. 框 It is the height of the top frame or middle frame panel.

[0014] Furthermore, the overall panel structure of the cooling tower series adopts split installation, which is assembled from modular panels, inspection doors, non-modular panels and top frame or middle frame panel parts into the overall panel structure of the cooling tower. Its width and height in any type of cooling tower should meet the following requirements: m﹒ W 模块化 +n﹒ W 非模块化 +W 门 =W 总 , i﹒ 模块化 +j﹒H 框 =H 总 , where m is the number of modular panels in the width direction, n is the number of non-modular panels in the width direction, and W 非模块化 is the non-modular panel width, W 总 is the total width of the cooling tower panel; i is the number of modular panels in the height direction, j is the number of top frame or middle frame panels in the height direction, H 总 It is the total height of the cooling tower panel.

[0015] Furthermore, the modular size optimization design comprehensively considers the overall size of the panels of all models of cooling towers in the whole series, counts and classifies the overall size of the panels in the whole series of cooling towers, and classifies those with the same or similar sizes into the same category to facilitate subsequent size design.

[0016] Furthermore, the modular size optimization design takes into account the overall aesthetics and symmetry of the cooling tower panel, and divides each type of panel into regions. Smaller cooling towers need to ensure that the panel is symmetrical on the left and right; medium and large cooling towers, in addition to ensuring that the panel is symmetrical on the left and right, also need to be divided into upper and lower parts.

[0017] Furthermore, the step 2 includes the following sub-steps:

[0018] Step 2-1: Refer to the existing panel size and set the inspection door width W 门 The modular panel width W is 1000 mm. 模块化 The initial value is 600mm. Substitute it into all models of cooling towers for calculation to obtain the number of modular panels m, the number of non-modular panels n, and the width W of non-modular panels required for each model in the width direction. 非模块化 ;

[0019] Step 2-2: Set the modular panel width W 模块化 The incremental step length is 50mm. After updating the width value, it is substituted into all models of cooling towers for calculation in turn to obtain the number of modular panels m, the number of non-modular panels n, and the width W of non-modular panels required for each model in the width direction. 模块化 ;

[0020] Step 2-3: Under the condition that the panel constraints are met, the width value is continuously updated, all feasible width solutions are traversed, and the above three parameters are comprehensively considered to determine the optimal width of a modular panel;

[0021] Step 2-4: Refer to the existing panel size and set the modular panel height H 模块化 The initial value is 1425mm. Substitute it into all models of cooling towers for calculation to obtain the number of modular panels i, the number of top frame or middle frame panels j, and the height H of the top frame or middle frame panels required for each model in the height direction. 框 ;

[0022] Step 2-5: Set the modular panel height H 模块化 The incremental step length is 50mm. After updating the height value, it is substituted into all models of cooling towers for calculation in turn to obtain the number of modular panels i, the number of top frame or middle frame panels j, and the height H of the top frame or middle frame panels required for each model in the height direction. 框 ;

[0023] Step 2-6: Under the condition that the panel constraints are met, the height value is continuously updated, all feasible height solutions are traversed, the above three parameters are comprehensively considered, and the panel height of the upper part of the medium and large models can be used in the small models. In the small and medium models, one optimal height of modular panels is determined, and 1 to 2 optimal heights of modular panels are determined in the medium and large models;

[0024] Step 2-7: Based on the optimal width of the modular panel determined in step 2-3 and the optimal height of the modular panel determined in step 2-6, finally determine the specifications of 2 to 3 models of modular panels.

[0025] Furthermore, the panel connection structure is a mixed connection form of snaps and bolts, and the number of bolts and snap connectors (snaps and their corresponding snap holes are collectively referred to as snap connectors) is selected according to actual needs of the panel. At the connection parts of adjacent panels, the bolts and snap connectors are evenly distributed and arranged alternately.

[0026] Based on the above method, the present invention also provides a cooling tower panel, including a panel body, wherein the four sides of the panel body are respectively formed into an upper folding edge, a lower folding edge, a left folding edge and a right folding edge by vertical bending; the ends of the upper folding edge, the lower folding edge, the left folding edge and the right folding edge are respectively formed into an upper flange, a lower flange, a left flange and a right flange by horizontal bending (the so-called vertical and horizontal are all based on the orientation of the panel body when it is placed horizontally); a plurality of buckles are provided on the left folding edge, and a plurality of buckle holes matching the buckles are provided on the right folding edge; the parts on both sides of the upper folding edge that contact the left folding edge and the right folding edge respectively, the parts on both sides of the lower folding edge that contact the left folding edge and the right folding edge respectively, the parts on both sides of the upper flange edge that contact the left flange and the right flange respectively, and the parts on both sides of the lower flange edge that contact the left flange and the right flange respectively, are connected and fixed by welding.

[0027] Compared with the prior art, the main beneficial effects of the present invention are:

[0028] 1. Taking into account the constraints such as the size of the cooling tower inspection door, panel area, panel raw material size and utilization rate, the designed modular panel is applied to the cooling tower structure, which makes it easier for maintenance workers of different sizes to pass through the inspection door. The modular panel is easy for installation workers to carry and install alone, while reducing the waste of raw materials in the production process and improving the utilization rate of raw materials.

[0029] 2. Comprehensively consider the overall size of the panels of the whole series of different models of cooling towers, consider the overall beauty and symmetry of the panel, take into account the size of the middle frame or top frame, and obtain the optimal panel size and combination form for the whole series of cooling tower models through size optimization design. The complex and diverse panel specifications are unified into 2 to 3 size specifications, which can better cover the installation requirements of the whole series of cooling towers of different sizes, facilitate the modular production of cooling tower panels, minimize the number of modules, reduce inventory and production costs, and improve production efficiency.

[0030] 3. The use of mixed connection of clips and bolts in conjunction with sealant materials greatly reduces the number of bolt installations, realizes convenient and efficient installation between cooling tower panels, saves manpower and time costs during installation, and ensures the strength and sealing between connections.

[0055] In order to facilitate those skilled in the art to more fully understand the technical solution of the present invention, the technical solution and its implementation method corresponding to an embodiment of the present invention are described in detail below in conjunction with the accompanying drawings.

[0056] like Figure 1 As shown, a panel design method for realizing serialization and modularization of cooling towers provided by the present invention includes the following three main steps:

[0057] Step 1, determine the constraints of the design size of the cooling tower panel;

[0058] Step 2, modular optimization design of the size of the cooling tower panel;

[0059] Step 3, complete the design of the cooling tower panel connection structure.

[0060] In this embodiment, the constraint conditions described in step 1 include the size of the cooling tower access door. Specifically, the access door opened on the access door panel should be convenient for maintenance workers of different sizes to pass through, and the height and width of the access door panel should meet the following requirements:

[0061] H 门 ≥1400mm (1)

[0062] W 门 ≥800mm (2)

[0063] In the formula, H 门 W is the height of the inspection door panel (in this embodiment, the length, width and height of the relevant components are in mm, the same below); 门 The width of the inspection door panel.

[0064] The constraints described in step 1 also include the area of ​​the modular panel. The modular panel should be easy for a single installer to carry and install, its area should not be too large, and its height should meet the following requirements:

[0065] H 模块化 ≤1900mm (3)

[0066] In the formula, H 模块化 is the modular panel height.

[0067] In addition to the above constraints, the constraints described in step 1 also include the size and utilization rate of the raw materials for modular panels. The specific requirements are: after being used to produce modular panels, the remaining raw materials can be further used to produce panels such as top frames or middle frames. At present, the raw material width of stainless steel plates purchased on the market is 1219mm, and the raw material width of aluminum-zinc plates and galvanized steel plates is 1250mm. Considering that the folding and flanging structures of the panel, top frame or middle frame require approximately 95mm of material respectively, and about 10mm is reserved for cutting, the panel width and the height of the top frame or middle frame panel should meet the following requirements:

[0068] W 模块化 +H 框 +2×95+10≤1219mm (4)

[0069] W 模块化 +H 框 +2×95+10≤1250mm (5)

[0070] Taking different materials into consideration, the sum of the width of the modular panel and the height of the top frame or middle frame panel should meet the following requirements:

[0071] W 模块化 +H框 ≤1019mm (6)

[0072] Where W 模块化 H is the width of the modular panel; 框 It is the height of the top frame or middle frame panel.

[0073] In the practical application of the present invention, the modular panel is assembled with the inspection door panel, the non-modular panel, the top frame or the middle frame panel and other panels to form a panel overall structure, and its width and height in any type of cooling tower should meet the following requirements:

[0074] m﹒ 模块化 +n﹒ W 非模块化 +W 门 =W 总 (7)

[0075] i﹒ 模块化 +j﹒H 框 =H 总 (8)

[0076] Where m is the number of modular panels in the width direction; n is the number of non-modular panels in the width direction; W 非模块化 W is the width of the non-modular panel (mm); 总 is the total width of the cooling tower panel (mm); i is the number of modular panels in the height direction; j is the number of top frame or middle frame panels in the height direction; H 总 It is the total height of the cooling tower panel (mm).

[0077] In this embodiment, the modular size optimization design described in step 2 first refers to comprehensively analyzing the overall size of the panels of all models of cooling towers in the whole series, and statistically classifying the overall size of the panels in the whole series of cooling towers. The panels with the same or similar sizes are classified into the same category to facilitate subsequent size design. In addition, the modular size optimization design described in step 2 should also consider the overall beauty and symmetry of the cooling tower panel, and divide the panels of each category into regions. Smaller cooling towers need to ensure that the panels are symmetrical on the left and right as a whole; in addition to ensuring that the panels are symmetrical on the left and right as a whole, medium and large cooling towers also need to be divided into two parts, upper and lower.

[0078] As a preferred embodiment of step 2, step 2 includes the following sub-steps:

[0079] Step 2-1: Refer to the existing panel size and set the inspection door width W 门 The modular panel width W is 1000 mm. 模块化 The initial value is 600mm. Substitute it into all models of cooling towers for calculation to obtain the number of modular panels m, the number of non-modular panels n, and the width W of non-modular panels required for each model in the width direction.非模块化 ;

[0080] Step 2-2: Set the modular panel width W 模块化 The incremental step length is 50mm. After updating the width value, it is substituted into all models of cooling towers for calculation in turn to obtain the number of modular panels m, the number of non-modular panels n, and the width W of non-modular panels required for each model in the width direction. 非模块化 ;

[0081] Step 2-3: Under the condition that the panel constraint conditions are met, the width value is continuously updated, all feasible width solutions are traversed, and the above three parameters are comprehensively considered to determine an optimal width of a modular panel. In this embodiment, the optimal width of the panel is determined to be 800 mm;

[0082] Step 2-4: Refer to the existing panel size and set the modular panel height H 模块化 The initial value is 1425mm. Substitute it into all models of cooling towers for calculation, and get the number of modular panels i (small cooling tower i=1, medium and large cooling tower i=2) required for each model in the height direction, the number of top frame or middle frame panel parts j (small and medium cooling tower j=1, large cooling tower j=2), the height H of the top frame or middle frame panel parts 框 ;

[0083] Step 2-5: Set the modular panel height H 模块化 The incremental step length is 50mm. After updating the height value, it is substituted into all models of cooling towers for calculation in turn to obtain the number of modular panels i, the number of top frame or middle frame panels j, and the height H of the top frame or middle frame panels required for each model in the height direction. 框 ;

[0084] Step 2-6: Under the condition that the panel constraint conditions are met, the height value is continuously updated, all feasible height solutions are traversed, the above three parameters are comprehensively considered, and the panel height of the upper part of the medium and large models can be used in the small model. One modular panel optimal height is determined in the small and medium models, and 1 to 2 modular panel optimal heights are determined in the medium and large models. In this embodiment, the determined optimal panel heights are 1475 mm and 1875 mm;

[0085] Step 2-7: Based on the optimal width of the modular panel determined in step 2-3 and the optimal height of the modular panel determined in step 2-6, finally determine 2 to 3 models of modular panel specifications. In this embodiment, the final determined modular panel specifications are 800mm×1475mm and 800mm×1875mm.

[0086] like Figure 2As shown, in the present embodiment, the design width of the main material 3 of the modular panel is 800mm, the design width of the main material 4 of the top frame or middle frame panel is 200mm, and the panel, top frame or middle frame panel require approximately 95mm wide materials to make the panel folding and flanging structure material 5 and the top frame or middle frame panel folding and flanging structure material 7, respectively. About 10mm is reserved for cutting, and the total width of the material used is approximately 1200mm, which is smaller than the width of the stainless steel plate raw material 1 and the aluminum zinc plate and galvanized steel plate raw material 2, thereby meeting the design requirements of panels of different materials and reducing the waste of raw materials.

[0087] like Figure 3 As shown, in this embodiment, the modular panel is designed to have a width of 800mm, and the height has two specifications of 1475mm and 1875mm to choose from, and finally two modular panel designs are obtained, namely, a modular panel 9 of model A with a specification of 800mm×1475mm and a modular panel 10 of model B with a specification of 800mm×1875mm. These two types of modular panels can better meet the existing panel installation requirements of cooling towers of different models. When implementing the present invention, the combination form between panels can be determined according to the installation conditions of cooling towers of different models, and panels of different specifications can be selected for installation. It is worth noting that some types of cooling towers, due to their particularity in structure or size, are difficult to combine into a complete cooling tower panel overall structure with only two types of modular panels of model A and model B. For this reason, the present invention realizes a complete cooling tower panel overall structure by adopting a technical means of combining non-modular panels with modular panels and other components such as top frame or middle frame panel parts, inspection door panels, etc. The so-called non-modular panel refers to a panel with poor versatility that is tailored for some cooling towers with special structures or sizes. Regarding the application of non-modular panels, this manual will combine Figures 6 to 9 Provide further explanation.

[0088] In this embodiment, the panel connection described in step 3 is a mixed connection form of buckles and bolts. Specifically, the number and position of the bolts and buckle connectors (the buckles and their corresponding buckle holes are collectively referred to as buckle connectors) on both sides of the modular panel are planned and designed. In the process of implementing the present invention, the number of bolts and buckle connectors is selected according to the actual needs of the panel. At the connection parts of adjacent panels, the bolts and buckle connectors are evenly distributed and arranged alternately as much as possible to ensure the connection strength between the panels.

[0089] like Figure 4 Combined with Figure 5As shown, the modular panel structure designed by steps 1 to 3 includes a panel body 11, an upper folding edge 12, a lower folding edge 18, a left folding edge 15, and a right folding edge 20; the upper folding edge 12, the lower folding edge 18, the left folding edge 15, and the right folding edge 20 are all formed by vertically bending the materials of the four sides of the panel body 11, and the ends of the upper folding edge 12, the lower folding edge 18, the left folding edge 15, and the right folding edge 20 are all horizontally bent to form an upper flange 13, a lower flange 19, a left flange 14, and a right flange 22 structure (the so-called vertical and horizontal are all referenced to the orientation when the panel body 11 is placed horizontally). Specifically, the above-mentioned panel body 11, the upper folding edge 12, the lower folding edge 18, the left folding edge 15, the right folding edge 20, the upper flange 13, the lower flange 19, the left flange 14, and the right flange 22 are formed by bending the same piece of stainless steel raw material 1 or the aluminum zinc plate, galvanized steel plate raw material 2.

[0090] In this embodiment, bolt holes 16 are formed on the panel body 11, the upper folding edge 12, the lower folding edge 18, the left folding edge 15, and the right folding edge 20. The bolt holes 16 on the panel body 11 can be used to connect the frame structure, the support column structure, the water pan structure, etc. inside the cooling tower; the bolt holes 16 on the upper folding edge 12 and the lower folding edge 18 can be used to connect the top frame panel member 27a or the middle frame panel member 27b structure, the water tank side panel 30 structure, the top guardrail structure, etc.; the bolt holes 16 on the left folding edge 15 and the right folding edge 20 can be used to connect adjacent panel structures.

[0091] Among them, the left folding edge 15 and the right folding edge 20 respectively contain buckles 17 and buckle holes 21, and the number and position of the buckles 17 and buckle holes 21 are designed according to the connection requirements of different cooling tower models. In this embodiment, a single modular panel is provided with 4 buckles 17 and 4 buckle holes 21. The buckles 17 on the left folding edge 15 and the buckle holes 21 on the right folding edge 20 are arranged correspondingly. The buckles 17 on the left folding edge 15 of one panel can be matched with the buckle holes 21 on the right folding edge 20 of another panel of the same height. Rapid positioning and assembly between two adjacent panels is realized.

[0092] The bolt holes 16 and buckles 17 on the left fold 15 are arranged alternately; the bolt holes 16 and buckle holes 21 on the right fold 20 are arranged alternately. The buckle connection positions and bolt connection positions are evenly distributed, so that the lateral positioning between the two adjacent panels is accurate, and at the same time, the buckle connection positions are not too concentrated, so as to ensure the connection strength between the adjacent panels.

[0093] Figures 6 to 9 This is a schematic diagram of the installation of the panel designed in this embodiment of the present invention in cooling towers of different sizes, including several representative models of cooling towers of various sizes in the full series of this embodiment.

[0094] Among them, the overall panel structure of the cooling tower series adopts a split installation, which is mainly assembled by modular panels 9, 10 in conjunction with non-modular panels 26, inspection door panels 32, top frame panel parts 27a or middle frame panel parts 27b. During actual installation, the number and arrangement of modular and non-modular panels can be determined according to the size and requirements of the cooling tower model to be installed, and modular panels 9, 10 and non-modular panels 26 of appropriate specifications and quantities can be selected from the inventory for standby. Then a certain thickness of sealant 23 material is evenly applied between the two panels to ensure the sealing of the cooling tower panel structure connection. First, the two panels are quickly positioned through the corresponding buckle holes 21 and buckles 17, and then fastened and connected through the fixing bolts 24 and the fixing nuts 25 to achieve installation and fastening between the two panels. The other modular panels 9, 10 and non-modular panels 26 are assembled horizontally in a similar manner, and the top frame panel 27a or the middle frame panel 27b are assembled vertically by fixing bolts 24 and fixing nuts 25 to complete the overall installation of the cooling tower panel.

[0095] like Figure 6 As shown, for the small-sized cooling tower in the series, only two B-type modular panels 10 and two non-modular panels 26 and the middle inspection door panel 32 are used for horizontal installation; the top is then vertically assembled and installed with a top frame panel 27a; the top of the top frame panel 27a is connected to the top plate and the tower top structure 28, etc., the bottom of the panel as a whole is connected to the water tank side plate 30, and the center of the bottom is arranged with a longitudinally installed center cylinder and its accessories 29 and other structures, and the bottom of the water tank is supported by the water tank support foot structure 31.

[0096] like Figure 7 As shown, for the first medium-sized cooling tower in the series, the upper part uses four A-type modular panels 9 and three non-modular panels 26 for horizontal installation; the lower part uses four A-type modular panels 9 and two non-modular panels 26, and the middle inspection door panel 32 for horizontal installation; and the middle part adds a middle frame panel 27b for vertical assembly installation. It should be noted that the middle frame or top frame panel is a long strip of plate structure made of the remaining part after the raw material is used to make the modular panel. In small-sized cooling towers, it is generally installed at the top, so it is called the top frame panel 27a; in medium and large-sized cooling towers, it is generally installed in the middle part, so it is called the middle frame panel 27b. The present invention adopts this technical means to save raw materials to the greatest extent.

[0097] like Figure 8As shown, it is a schematic diagram of an installation method of the panel designed for the present invention in this embodiment. For the second medium-sized cooling tower in the series, the upper part adopts four A-type modular panels 9 and three non-modular panels 26 for horizontal installation; the lower part adopts four B-type modular panels 10 and two non-modular panels 26 and the middle inspection door panel 32 for horizontal installation; and a middle frame panel 27b is added to the middle part for vertical combination installation.

[0098] like Fig. 9 As shown, it is a schematic diagram of an installation method of the panel designed for the present invention in this embodiment. For large-sized cooling towers in the series, the upper part adopts six B-type modular panels 10 and three non-modular panels 26 for horizontal installation; the lower part adopts six B-type modular panels 10 and two non-modular panels 26 and the middle inspection door panel 32 for horizontal installation; and two middle frame panel members 27b are added to the middle part for vertical combined installation.

[0099] For other series of cooling towers, modular panel design can also be carried out through the same methods and steps. The structures of cooling towers of different models and sizes can be comprehensively considered to determine 2 to 3 modular panels suitable for the entire series, so as to realize the serialization and modular production of panels, minimize the number of modules, reduce inventory and production costs, and improve production efficiency.
