Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical cooling tower circulating cooling water water-saving technology, in particular to a cooling tower water removal and white elimination cover. BACKGROUND

[0002] For power plants, coal chemical industry, petroleum chemical industry, steel and iron and steel industry, it is necessary to use cooling towers to produce a large amount of cooling water to cool condensers, generators, auxiliary machines, chemical process devices and equipment, blast furnaces, refining furnaces and other equipment and devices, so as to ensure the normal operation of the entire process system. The mechanical ventilation cooling tower currently widely used has a large amount of cooling water loss due to its own evaporation, and is also prone to form hot plume mist.

[0003] During the operation of the cooling tower, the outflow gas will mix with the surrounding atmosphere above the cooling tower and condense, and water droplets will be separated to form plume mist. The generation of plume mist will accelerate the corrosion of surrounding equipment or devices, especially for air-cooled island insulator equipment, under long-time dense fog weather, the end of the insulator will produce corona and local arc discharge phenomenon, affecting the normal production and operation of industrial enterprises. The main measures for preventing pollution flashover of the air-cooled island of the power plant at present are: ① spraying anti-pollution flashover material on the surface of the equipment to improve the anti-pollution flashover performance of the power equipment and ensure the safe operation of the power equipment; ② installing anti-pollution flashover auxiliary umbrella skirt, bonding and installing climbing auxiliary umbrella skirt on the original porcelain bottle and porcelain insulator to form composite insulation; ③ taking auxiliary anti-pollution flashover measures for artificial prevention; ④ reasonable voltage reduction operation in special weather to reduce the probability of equipment pollution flashover trip; ⑤ common box bus technology transformation; ⑥ strengthening the detection of zero value and low value insulators.

[0004] By installing a corrugated plate water collector in the cooling tower to reduce water loss, this method can only intercept large droplets with a diameter greater than a certain value in the backflow, and a large part of the small droplets will enter the atmosphere with the natural wind in the cooling tower, causing a large part of the water loss and wasting water resources.

[0005] However, the current measures adopted by the power plant, such as spraying anti-pollution flashover material on the surface of the equipment, installing anti-pollution flashover auxiliary umbrella skirt, common box bus technology transformation, and strengthening the detection of zero value and low value insulators, are to solve the problem of anti-pollution flashover from the aspects of equipment modification and artificial intervention, and do not consider reducing rain and mist, which cannot fundamentally solve the problems of cooling water loss and rain and mist pollution flashover.

[0020] Further, a hoop ring and a hoop rope are arranged on the woven unit.

[0021] A plurality of hoop rings are arranged on the woven unit in the radial direction, and the hoop rope passes through the hoop ring closest to the folded part of all the woven units and is tied, thereby forming an open structure.

[0022] Further, the woven unit is composed of a plurality of fan-shaped pieces.

[0023] Two adjacent fan-shaped pieces are fixedly connected by a strap.

[0050] Embodiment 1

[0051] As shown in Figure 1 , 7 , the cooling tower water removal and white cover provided by the present embodiment includes a cover body 1 and a support frame 2.

[0052] The support frame 2 is arranged at the top end of the cooling tower.

[0053] The cover body 1 is arranged on the support frame 2 and fixedly connected with the support frame 2.

[0054] The cover body 1 is a circular or annular structure.

[0055] As a further embodiment of the present embodiment, the cover body 1 is formed into a circular or annular structure by splicing a plurality of woven fabric units 3.

[0056] As a further embodiment of the present embodiment, the cover body 1 is made of one or more weaving methods of the weave, weft knitting, warp knitting organization.

[0057] As a further embodiment of the present embodiment, the cover body 1 is annular, and the inner diameter thereof is provided with an opening structure 4 for adjusting the ventilation volume of the cooling tower.

[0058] As a preferred embodiment of the present embodiment, the cooling tower water removal and white elimination cover is made of a plurality of composite materials, including but not limited to: three-dimensional (3D) woven nylon mesh, three-dimensional (3D) woven polyester mesh, ultra-high molecular weight polyethylene tape, dacron tape, ultra-high molecular weight polyethylene yarn, dacron yarn, macromolecular polyester fiber, and ultra-high molecular weight polyester fiber. The material used can also be one or more of the above-listed materials.

[0059] In actual use, the support frame 2 is first arranged at the top end of the cooling tower, and then the cover body 1 is arranged on the support frame 2. Alternatively, the cover body 1 and the support frame 2 can be integrally connected first and then arranged at the top end of the cooling tower. The water removal and white elimination cover is installed inside or outside the top end of the cooling tower, and without changing the original working condition of the cooling tower, the mechanical ventilation cooling tower outlet flow field is changed to block the backflow of the droplets and the feather mist in the hot and humid airflow. The cover body 1 is circular or annular. When the cover body 1 is circular, the overall mechanical properties of the cover body 1 are excellent, and damage or rupture is less likely to occur. Moreover, the cover body 1 can liquefy the water vapor and return it to the cooling tower, improving water-saving performance. When the cooling load of the cooling tower is large, the ventilation volume needs to be increased to improve the cooling efficiency. In this case, the cover body 1 is arranged in an annular structure, and the inner diameter of the annular structure is an opening structure 4. The opening structure 4 is a fixed structure or an adjustable structure.

[0060] By adopting the above technical solution, the present application has the following beneficial effects:

[0061] (1) The cover body 1 is designed in a circular or annular structure, which can adapt to cooling towers of different specifications and shapes. At the same time, the fixed connection between the cover body 1 and the support frame 2 ensures the stability of the entire structure and reduces the likelihood of damage or rupture.

[0062] (2) A plurality of composite materials, such as three-dimensional (3D) woven nylon mesh, polyester mesh, and ultra-high molecular weight polyethylene tape, are used. These materials not only have excellent mechanical properties but also have good weather resistance and corrosion resistance, which can ensure the stability and durability of the cover body 1 during long-term use.

[0063] (3) When the cover body 1 is designed in an annular shape, the inner diameter thereof is provided with an opening structure 4. This design allows the ventilation volume to be adjusted according to the cooling load of the cooling tower. When the cooling load is large, the opening structure 4 can be increased to increase the ventilation volume and improve the cooling efficiency. At the same time, the cover body 1 can liquefy the water vapor and return it to the cooling tower, effectively reducing the waste of water resources and improving water-saving performance.

[0064] (4) The design of the support frame 2 and the cover 1 makes the installation process simple and quick. In addition, the cover 1 is made up of multiple woven units 3 spliced ​​together. This modular design makes it easy to disassemble and replace, reducing maintenance costs.

[0065] (5) The water removal and whitening cover is installed at the top of the cooling tower, which can change the flow field at the outlet of the mechanical ventilation cooling tower duct, effectively blocking and recirculating the droplets and mist in the hot and humid airflow, thereby improving the operating efficiency and environmental performance of the cooling tower.

[0066] Example 2

[0067] like Figures 2-4 As shown, this embodiment provides a specific structure of the cover 1 in Embodiment 1.

[0068] The woven unit 3 is fan-shaped, and multiple woven units 3 are spliced ​​together in the circumferential direction to form the cover 1;

[0069] The two adjacent woven fabric units 3 are connected by a connecting structure.

[0070] As a further embodiment of this example, the connection structure is a sewn connection structure, a welded connection structure, or an adhesive connection structure.

[0071] As a further embodiment of this embodiment, the woven unit 3 is provided with a connecting cord 5;

[0072] A connecting ring 6 is provided on the outer edge of the support frame 2, and the connecting ring 6 passes through the through hole provided at the corresponding position of the woven unit 3 and exits the woven unit 3;

[0073] One end of the connecting cable 5 is located at the fan-shaped tip of the braided unit 3, and the other end is tied to the connecting ring 6, so that the braided unit 3 is folded, and the connection position of the connecting cable 5 and the connecting ring 6 can be adjusted according to the required opening size to achieve the adjustment of the opening size.

[0074] As a further embodiment of this embodiment, the woven unit 3 is also provided with a hoop 7 and a hoop cord 8;

[0075] Multiple hoop rings 7 are arranged radially on the woven unit 3, and the hoop cable 8 passes through all the hoop rings 7 closest to the fold on the woven unit 3 and is tightened, thereby forming an open structure 4.

[0076] In practical use, the cooling tower dewatering and whitening cover disclosed in this application first determines the diameter of the required opening structure 4. If no opening is needed, multiple fan-shaped woven units 3 can be directly spliced ​​together to obtain a circular cover 1. If an opening is required, the fan-shaped woven units 3 are folded according to the radius of the opening, and the connecting cable 5 is tied to the connecting ring 6 to prevent the folded parts from unfolding again. In addition, the hoop cable 8 is passed through the hoop ring 7 closest to the fold on all woven units 3 and tied tightly, so that the diameter of the opening structure 4 is fixed, preventing changes in the diameter of the opening structure 4 due to external forces from affecting the cooling performance and water-saving effect of the cooling tower. When it is necessary to adjust the diameter of the opening structure 4, simply untie the hoop cable 8, adjust the folding position of the woven unit 3, and then retighten the connecting cable 5 and the hoop cable 8.

[0077] By adopting the above technical solution, this application has the following beneficial effects:

[0078] (1) The woven unit 3 is designed in a fan shape, which makes it easy to splice in the circumferential direction to form a complete cover 1. This modular design not only simplifies the manufacturing and installation process, but also allows the cover 1 to be customized according to actual needs, improving flexibility and adaptability.

[0079] (2) Adjacent woven units 3 are connected by stitching, welding or bonding, which ensures the overall stability and durability of the cover 1. At the same time, the diverse connection methods provide more options for different application scenarios and meet the needs of different customers.

[0080] (3) The size of the opening on the cover 1 can be easily adjusted by the design of the connecting cable 5 and the connecting ring 6. This design allows the cover 1 to be flexibly adjusted according to the cooling load and ventilation requirements of the cooling tower, thereby improving cooling efficiency and water-saving performance.

[0081] (4) The design of the hoop 7 and the hoop cable 8 further enhances the stability of the opening structure 4. Multiple hoop 7s are arranged radially on the braided unit 3, and the hoop cable 8 passes through all the hoop 7s closest to the fold on the braided unit 3 and is tightened, thereby fixing the diameter of the opening structure 4. This design effectively prevents the diameter of the opening structure 4 from changing due to external forces, ensuring the stable operation of the cooling tower and water-saving effect.

[0082] (5) When it is necessary to adjust the diameter of the opening structure 4, simply untie the hoop 8, adjust the folding position of the woven unit 3, and then re-tighten the connecting cable 5 and the hoop 8. This design makes the maintenance and adjustment of the cover 1 simple and quick, reducing maintenance costs and time.

[0083] (6) By adjusting the size of the opening on the cover body 1, the ventilation volume of the cooling tower can be optimized, and the cooling efficiency can be improved. At the same time, the cover body 1 can block the droplets and mist in the hot and humid airflow, reduce the waste of water resources, and improve the water-saving performance.

[0084] Embodiment 3

[0085] As shown in Figures 5-6 , the embodiment provides a specific structure of the cover body 1 in Embodiment 1.

[0086] Different from Embodiment 2, the woven fabric unit 3 is composed of a plurality of sector-shaped patches 9.

[0087] The adjacent two sector-shaped patches 9 are fixedly connected through the binding belt.

[0088] As a further implementation manner of the embodiment, the inner side of the sector-shaped patch 9 is provided with a hoop pipe 10.

[0089] The hoop rope 8 passes through the hoop pipes 10 on the innermost end sector-shaped patches 9 of all the woven fabric units 3 and is tied to form a stable opening structure 4.

[0090] In actual use, the cooling tower water removal and white elimination cover disclosed in the application first determines the diameter of the required opening structure 4, arranges and connects a plurality of sector-shaped patches 9 in the circumferential direction to form the woven fabric unit 3 according to the size of the opening structure 4, and the specific connection manner can adopt the connection structure in Embodiment 2, which will not be described here. When it is necessary to adjust the size of the opening structure 4, the patch on the inner side can be increased or reduced on the basis. In order to strengthen the stability of the opening structure 4, the inner side of the sector-shaped patch 9 is provided with a hoop pipe 10, and the hoop ring passes through the hoop pipes 10 on the innermost end sector-shaped patches 9 of all the woven fabric units 3 and is tied to constrain the shape and size of the opening structure 4, so as to prevent the diameter change of the opening structure 4 caused by external force from affecting the cooling performance and water-saving effect of the cooling tower.

[0091] By adopting the above technical solution, the application has the following beneficial effects:

[0092] (1) The woven fabric unit 3 is composed of a plurality of sector-shaped patches 9, and this modular design makes the cover body 1 easy to expand or shrink according to actual needs. By increasing or reducing the number of sector-shaped patches 9, the size of the opening structure 4 can be easily adjusted to meet the ventilation and water-saving needs of different cooling towers.

[0093] (2) The adjacent fan-shaped pieces 9 are fixedly connected by the binding straps, which is simple and quick, and does not require complex processes or equipment. At the same time, the use of the binding straps also provides additional flexibility, allowing the cover 1 to have a certain deformation capacity when subjected to external forces, thereby better adapting to the operating environment of the cooling tower.

[0094] (3) The inner side of the fan-shaped pieces 9 is provided with a hoop pipe 10, and the hoop rope 8 passes through the hoop pipes 10 on the innermost fan-shaped pieces 9 of all the woven units 3 and is tied tight, forming a stable opening structure 4. This design not only enhances the stability of the opening structure 4, but also prevents the diameter of the opening structure 4 from changing due to external forces, thereby ensuring the cooling performance and water-saving effect of the cooling tower.

[0095] (4) Since the woven unit 3 is composed of multiple fan-shaped pieces 9, and the adjacent pieces are connected by binding straps, the maintenance and adjustment of the cover 1 becomes very simple. When it is necessary to adjust the size of the opening structure 4 or perform maintenance, it is only necessary to untie the binding straps, rearrange or replace the pieces, and then tie them again.

[0096] (5) By adjusting the size of the opening structure 4, the ventilation volume of the cooling tower can be optimized, thereby improving the cooling efficiency. At the same time, the cover 1 can block the droplets and feather mist in the humid hot airflow, reduce the waste of water resources, and improve the water-saving performance.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solutions of the embodiments of the present application.
