Description

Technical Field

[0001] The present invention belongs to the technical field of haze removal, and more specifically, relates to a haze removal screen and a construction method. Background Art

[0002] Electrostatic adsorption haze removal equipment is widely used in indoor and outdoor air purification applications due to its high efficiency and low energy consumption. Electrostatic haze removal systems, which use electrode wires and wire mesh as cathodes and anodes, respectively, charge airborne particles through a high-voltage electric field, attracting them to the anodes. This has become a mainstream technology.

[0003] In existing electrostatic haze removal equipment, electrode wires are mostly installed by fixed welding or single bolt fastening. Once the electrode wires become loose due to long-term use or break due to vibration or temperature changes, adjusting or replacing the electrode wires requires disassembling the entire frame. The operation is cumbersome and requires professionals to work for a long time, which increases the difficulty of the operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a haze removal screen, which aims to solve the problem that the adjustment or replacement of electrode wires requires disassembly of the entire frame, which is cumbersome and requires professionals to work for a long time, thereby increasing the difficulty of the operation.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: providing a haze removal screen, comprising at least two spaced support frames, two anode frames connected between two adjacent support frames, the two anode frames being spaced apart and arranged parallel to each other, a cathode frame being arranged between the two anode frames, and both sides of the cathode frame being insulated and connected to the support frame on the same side; A plurality of electrode wires are arranged at intervals in the cathode frame, the upper ends of the electrode wires are connected to the top of the cathode frame, and the lower ends of the electrode wires are provided with adjustment components that are detachably connected to the bottom of the cathode frame, and the adjustment components are used to adjust the axial tightness of the electrode wires; A metal mesh is provided in the anode frame. A plurality of connecting bolts are symmetrically provided on both sides of the anode frame. The connecting bolts are axially and horizontally connected to the support frame on the same side.

[0006] In a possible implementation, the support frame includes a plurality of support platforms spaced apart longitudinally, and both sides of the cathode frame are provided with outwardly extending connecting portions, which are connected to the support platforms on the same side via an insulator string.

[0007] In a possible implementation, the support platform is an I-shaped platform, and left and right sides of the I-shaped platform are provided with avoidance grooves for avoiding side edges of the cathode frame.

[0008] In one possible implementation, each of the support frames has four support platforms arranged longitudinally at intervals, and each of the cathode frames has two connecting portions arranged vertically at intervals on both sides, and the insulator strings are connected between the second-layer support platform and the upper connecting portion, and between the fourth-layer support platform and the lower connecting portion.

[0009] In one possible implementation, a protective plate is provided on the facade of the support frame; when the support frame is located at the end of the haze removal screen, the protective plate is wrapped around the front and rear facades and the outer facade of the support frame; when the support frame is located in the middle of the haze removal screen, the protective plate is wrapped around the front and rear facades of the support frame.

[0010] In a possible implementation, an upper sealing plate is provided on the top of the support frame, and a shape of the upper sealing plate is adapted to a combined cross-sectional shape of the support frame and the protective plate.

[0011] In one possible implementation, the adjustment assembly includes an adjustment screw, the upper end of which is rotatably connected to the lower end of the electrode wire, the lower end of which is rotatably connected to the lower end of the cathode frame, and the adjustment screw and the electrode wire are coaxial.

[0012] The beneficial effect of the haze removal screen provided by the present invention is that compared with the prior art, among the multiple connecting bolts symmetrically arranged on both sides of the anode frame, the non-top bolts can be removed separately. When it is necessary to operate the internal electrode wire, it is only necessary to remove the non-top connecting bolts to rotate the anode frame outward around the top connection point to open it, without the need to disassemble the entire support frame, which greatly simplifies the exposure process of the internal cathode frame. Inside the cathode frame, the axial tightness of the electrode wire can be directly fine-tuned by adjusting the assembly without the need to disassemble the electrode wire body. In addition, the adjustment assembly adopts a detachable design. When the electrode wire needs to be replaced, it is only necessary to separate the connection between the adjustment assembly and the bottom of the cathode frame to quickly remove the old electrode wire and install the new wire, avoiding the complicated process of disassembling the cathode frame to replace the electrode wire in the traditional solution. The haze removal screen provided by the present invention effectively reduces the steps and time of electrode wire maintenance operations through a split connection design and a modular adjustment structure, reduces the technical dependence on professionals, and significantly improves the convenience of operation.

[0013] The present invention also provides a construction method for a haze removal screen, comprising the following steps: S1: Preparation before construction: clear the debris in the construction area and level the ground, check the specifications and quantity of each component of the haze removal screen, check the integrity of the components, and prepare construction tools and equipment; S2: Install the support frame. Determine the installation position and height of the support frame according to the design drawings. Place the support frame according to the layout and adjust the verticality and horizontality before fixing it. Check the position, flatness and strength of the support platforms arranged longitudinally on the support frame. S3: Install the cathode frame. Connect the lower end of the insulator string to the support platform, connect the upper end of the insulator string to the outward-extending connection parts on both sides of the cathode frame, and adjust the position and verticality of the cathode frame. S4: Electrode wire installation and adjustment: Arrange multiple electrode wires in the cathode frame according to the designed intervals. Connect the upper end of the electrode wire to the top of the cathode frame, and install an adjustment component at the lower end to adjust the axial tightness of the electrode wire to a suitable tension state. S5: Anode frame installation: Install the wire mesh inside the anode frame and ensure it is firm and flat. Place two anode frames parallel to each other between adjacent support frames. Connect the support frames on the same side axially and horizontally with the connecting bolts symmetrically arranged on both sides of the anode frame. Adjust the position and levelness of the anode frame. S6: Overall debugging and inspection, comprehensively check the correctness of installation and firmness of connection of each component, detect the insulation performance between cathode frame and support frame and the electrical connection status of each component, start the running system for trial operation and observe the running status.

[0014] In one possible implementation, after step S5, according to the end or middle position of the support frame in the haze removal screen, the protective plate is wrapped around the front and rear facades and the outer facades or only the front and rear facades of the support frame, and an upper sealing plate adapted to the cross-sectional shape of the combination of the support frame and the protective plate is installed on the top of the support frame.

[0015] In one possible implementation, if the electrode wire is loose or broken, remove the non-top connection bolts on both sides of any anode frame, and rotate the anode frame outward using the top connection bolts on both sides of the anode frame as the rotation axis; Adjust the loose electrode wire by adjusting the assembly so that its axial tightness reaches the appropriate tension state; or remove the connection between the broken electrode wire and the top and bottom of the cathode frame, reinstall the new electrode wire, first install the upper end of the electrode wire, then install the lower end of the electrode wire, and adjust the axial tightness of the electrode wire to the appropriate tension state by adjusting the assembly; After the electrode wires are tightened or replaced, the anode frame is rotated inward using the connecting bolts at the tops of both sides of the anode frame as the rotation axis, and the non-top connecting bolts on both sides of the anode frame are installed in sequence from top to bottom.

[0016] The construction method for the haze-removing screen provided by the present invention offers the following advantages: Compared to existing technologies, the pre-construction preparation steps explicitly require the removal of debris and leveling of the ground, as well as the verification of component specifications, quantity, and integrity, and the preparation of tools and equipment. This step preemptively eliminates environmental interference and component hazards, avoids construction interruptions caused by missing tools or component problems, lays the foundation for smooth subsequent construction, and improves overall construction efficiency. The support frame installation emphasizes positioning and laying out according to the design drawings, adjusting verticality and horizontality, and then securing it. The position, flatness, and strength of the support platform are then checked to ensure that the support frame, as the foundation of the overall structure, is accurately installed and meets the required load-bearing capacity. This prevents deviations in subsequent component installation due to frame tilt or unstable support platforms. The cathode frame installation involves connecting the support platform to the cathode frame using an insulator string and adjusting their position and verticality. The anode frame installation ensures parallel spacing between the front and rear, horizontally connecting them with connecting bolts, and adjusting their horizontality. These three steps collaboratively ensure the relative positional accuracy of the cathode frame, anode frame, and support frame, providing the structural prerequisite for the subsequent functional performance of the electrode wires and wire mesh, and reducing the problem of reduced haze removal efficiency due to installation misalignment. During the electrode wire installation and adjustment steps, the adjustment assembly is used to adjust the tightness of the electrode wire without the need for additional disassembly of the structure. The operation is simple and the tension state of the electrode wire can be accurately controlled to ensure that the electrode wire is in the best working shape. When installing the anode frame, the metal mesh is first fixed in the frame and then the overall connection is made. This avoids the space limitation of installing the frame first and then installing the mesh, reduces the difficulty of operation, and the horizontal connection method of the connecting bolts also reserves convenience for subsequent maintenance. The overall debugging and inspection steps cover the correctness of component installation, connection firmness, insulation performance, electrical connection status and trial operation observation. Multi-dimensional detection can comprehensively check for installation hazards. Through trial operation, system operation problems can be discovered in advance and corrected in time, avoiding shutdown maintenance due to hidden faults after formal commissioning, significantly improving the safety and stability of the haze removal screen operation, and extending the service life of the equipment. The construction method of the haze removal screen provided by the present invention not only ensures the construction quality and efficiency through step-by-step control, precise adjustment and comprehensive testing, but also provides guarantees for the long-term reliable operation of the equipment, effectively reducing construction and later operation and maintenance costs.

DETAILED DESCRIPTION

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See also Figures 1 to 8The haze removal screen provided by the present invention will now be described. The haze removal screen comprises at least two spaced support frames 100, two anode frames 200 connected between adjacent support frames 100, the two anode frames 200 being spaced apart and arranged parallel to each other in a front-to-back manner, a cathode frame 300 being disposed between the two anode frames 200, and the two sides of the cathode frame 300 being insulated and connected to the support frame 100 on the same side; a plurality of electrode wires 310 spaced apart within the cathode frame 300, the upper ends of the electrode wires 310 being connected to the tops of the cathode frames 300, and the lower ends of the electrode wires 310 being provided with adjustment components detachably connected to the bottoms of the cathode frames 300, the adjustment components being used to adjust the axial tightness of the electrode wires 310; a metal mesh 210 being disposed within the anode frame 200, and a plurality of connecting bolts 220 being symmetrically disposed on both sides of the anode frame 200, the connecting bolts 220 being axially and horizontally connected to the support frame 100 on the same side.

[0024] Compared with the prior art, the haze removal screen provided by the present invention has multiple connecting bolts 220 symmetrically arranged on both sides of the anode frame 200, and the non-top bolts can be removed separately. When it is necessary to operate the internal electrode wire 310, it is only necessary to remove the non-top connecting bolts 220 to rotate the anode frame 200 outward around the top connection point to open it, without disassembling the entire support frame 100, which greatly simplifies the exposure process of the internal cathode frame 300. Inside the cathode frame 300, the axial tightness of the electrode wire 310 can be directly fine-tuned through the adjustment component without disassembling the electrode wire 310 body. In addition, the adjustment component adopts a detachable design. When the electrode wire 310 needs to be replaced, it is only necessary to separate the connection between the adjustment component and the bottom of the cathode frame 300 to quickly remove the old electrode wire 310 and install a new one, avoiding the complicated process of disassembling the cathode frame 300 in the traditional solution to replace the electrode wire 310. The haze removal screen provided by the present invention effectively reduces the steps and time of electrode line 310 maintenance operations through a split connection design and a modular adjustment structure, reduces technical dependence on professionals, and significantly improves operational convenience.

[0025] See also Figures 3 and 4 The support frame 100 has a plurality of support platforms 110 arranged at intervals in the longitudinal direction. Connecting portions 320 extending outward are respectively provided on both sides of the cathode frame 300. The connecting portions 320 are connected to the supporting platforms 110 on the same side via insulator strings 130. The supporting platforms 110 arranged at intervals in the longitudinal direction provide the cathode frame 300 with multiple and uniform support points, thus avoiding the problems of concentrated force and easy tilting of the cathode frame 300 that may be caused by traditional single-point support. At the same time, the cathode frame 300 is connected to the support platform 110 through the connecting portions 320 extending outward on both sides, so that the connection points are closer to the center of gravity of the frame, further improving the overall stability of the cathode frame 300 after installation, effectively resisting external interference such as wind, and reducing the risk of structural deformation during long-term use.

[0026] As the insulating medium between the cathode frame 300 and the support frame 100, the insulator string 130 can completely block the current conduction path between the cathode frame 300 and the support frame 100, avoiding leakage and short circuit problems caused by direct contact between the two. The longitudinal spacing design of the support platform 110 provides a clear and fixed installation point for the docking of the insulator string 130 and the connection portion 320 of the cathode frame 300, eliminating the need for temporary on-site adjustment of the support position, reducing the difficulty of installation and positioning. At the same time, the outward-extending connection portion 320 increases the operating space between the cathode frame 300 and the support frame 100. If it is necessary to check the status of the insulator string 130 or maintain the cathode frame 300 later, the staff can more conveniently access the connection parts without disassembling the main frame, thereby improving maintenance efficiency.

[0027] See also Figure 5 The support platform 110 is an I-shaped platform, and the left and right sides of the I-shaped platform are provided with avoidance grooves 111 for avoiding the side edges of the cathode frame 300. The avoidance grooves 111 on the left and right sides of the I-shaped platform avoid the side edges of the cathode frame 300, avoiding structural interference between the traditional flat-plate support platform 110 and the side edges of the cathode frame 300. When the cathode frame 300 is docked with the support platform 110 through the connection part 320, the avoidance grooves 111 can provide accommodation space for the side edges of the cathode frame 300, without the need for additional polishing or adjustment of the frame size, ensuring that the cathode frame 300 can accurately fit the preset installation position of the support platform 110, reducing installation deviations caused by structural conflicts, and indirectly ensuring the uniformity of the subsequent electrode line 310 arrangement and the relative position accuracy of the cathode frame 300 and the anode frame 200. The presence of the avoidance grooves 111 increases the operating space of the connection between the cathode frame 300 and the support platform 110. When installing the insulator string 130, workers do not need to avoid the obstruction of the side of the cathode frame 300, and can complete the bolt tightening, position adjustment and other operations of the insulator string 130 more smoothly, avoiding the problem of limited tool use due to narrow space, shortening the installation time of a single set of connection structures, and improving overall construction efficiency.

[0028] In addition, the I-shaped platform itself has a mechanically optimized structure of upper and lower flanges and a middle web. With the same material usage, its bending and shear strengths are much higher than those of a flat-plate platform. It can stably bear the weight of the cathode frame 300 and the electrode wire 310, and avoid deformation of the platform during long-term use. At the same time, the design of the avoidance groove 111 reduces the material usage in non-essential areas of the platform while ensuring structural strength, thereby achieving weight reduction and material saving, reducing the overall weight of the support frame 100 and controlling manufacturing costs, taking into account both practicality and economy.

[0029] See also Figures 3 and 4Each support frame 100 has four support platforms 110 spaced apart in the longitudinal direction. Each cathode frame 300 has two connecting portions 320 spaced apart in the vertical direction on either side. Insulator strings 130 are connected between the second-level support platform 110 and the upper connecting portion 320, and between the fourth-level support platform 110 and the lower connecting portion 320. The combination of the four support platforms 110 and the two connecting portions 320 forms a two-point support structure, with the support points located on the second and fourth longitudinal layers of the support frame 100, respectively. This evenly distributes the load points on the cathode frame 300 in the middle and lower longitudinal regions, avoiding the risk of tilting caused by excessive concentration of support points at the top or bottom. Furthermore, the two-point support effectively limits the horizontal and vertical displacement of the cathode frame 300. Even in the face of external forces such as wind, the tension of the insulator strings 130 and the load-bearing capacity of the support platforms 110 maintain the stability of the frame, reducing structural deformation during long-term use and providing reliable protection for the precise arrangement of the electrode wires 310. The two connecting parts 320 spaced apart from each other correspond to the second and fourth support platforms 110 respectively, so that the longitudinal force of the cathode frame 300 is evenly distributed to the two support points, avoiding the problem of local force overload caused by single-point support, and extending the service life of the insulator string 130 and the connecting part 320.

[0030] See also Figure 5 The second and fourth support platforms 110 are respectively screwed or welded with mounting trays 120, and the lower ends of the insulator strings 130 are longitudinally fixed to the upper end surfaces of the mounting trays 120. The mounting tray 120 comprises a bottom mounting plate and an upper connecting plate. The mounting plate is screwed to the support platform 110, and the connecting plate is welded to the upper end of the mounting plate for connecting the lower ends of the insulator strings 130 to keep the insulator strings 130 in a vertical position. The connecting portion 320 is a connecting rod welded to the outside of the cathode frame 300. The connecting rod is perpendicular to the side wall of the cathode frame 300, and the upper ends of the insulator strings 130 are vertically connected to the connecting rod. The dual positioning of the upper and lower parts ensures that the insulator strings 130 always remain vertical, avoiding tilting that causes the cathode frame 300 to shift, accurately maintaining the electrode spacing, and ensuring the uniformity of the electric field and the dust removal efficiency.

[0031] See also Figure 1 and Figure 7, a protective plate 150 is provided on the facade of the support frame 100; when the support frame 100 is located at the end of the haze removal screen, the protective plate 150 is wrapped around the front and rear facades and the outer facade of the support frame 100; when the support frame 100 is located in the middle of the haze removal screen, the protective plate 150 is wrapped around the front and rear facades of the support frame 100. For the end support frame 100, the protective plate 150 wraps the front and rear facades and the outer facades to form a three-sided protection structure. The outer facade directly faces the external environment, which can effectively prevent the erosion of the frame body by outdoor wind, sand, rain, debris, etc., and prevent the metal frame from rusting due to long-term exposure; the protection of the front and rear facades can isolate the dust accumulation that may be generated inside the haze removal screen during operation or the potential interference when the electrode wire 310 is working, while preventing people from accidentally touching the end frame and causing safety risks. The middle support frame 100 only needs to wrap the front and rear facades, because the middle position does not need to face the external environment. While ensuring the protection of the front and rear sides of the frame, it can reduce the use of unnecessary protective plates 150, achieve a balance between protection and cost, and avoid material waste.

[0032] Preferably, the protective plate 150 is an arc-shaped plate with a central portion that bulges outward. This outward bulge significantly improves wind resistance and drainage performance. In strong winds, the curved surface guides airflow smoothly along the surface, reducing the impact of wind resistance on the support frame 100 and preventing the frame from shaking or deformation of the protective plate 150 caused by direct wind force. Furthermore, in rainy and snowy weather, the inclined surface of the arc structure accelerates the sliding of rain and snow, preventing accumulation of rain and snow on the surface of the protective plate 150.

[0033] Furthermore, compared to flat plates, the curved plate with a central protrusion can disperse external forces across the entire curved surface, reducing localized force concentration and making it less susceptible to damage such as dents and fractures, thereby enhancing the protective capability of the protective plate 150 for the support frame 100. Furthermore, the curved design reduces the joint gaps between the protective plate 150 and the stress and deformation of a single plate, making it less susceptible to cracking due to temperature fluctuations and external forces during long-term use, further enhancing the stability and durability of the protective system.

[0034] See also Figure 1 and Figure 8The top of the support frame 100 is provided with an upper sealing plate 160, and the shape of the upper sealing plate 160 is adapted to the combined cross-sectional shape of the corresponding support frame 100 and the protective plate 150. The upper sealing plate 160 can completely cover the gaps and vacant areas at the top of the support frame 100. For the end support frames 100, the adapted upper sealing plate 160 can form a top closed-loop protection, preventing rainwater, dust, fallen leaves and other debris from penetrating into the interior of the support frame 100 from the top, and preventing the internal support platform 110 and the connection part 320 of the insulator string 130 from rusting or degrading the insulation performance due to the accumulation of debris; for the middle support frame 100, the upper sealing plate 160 can fill the exposed area at the top of the frame, preventing dust generated during the haze removal process from drifting from the top to the outside of the frame, and at the same time preventing foreign matter from falling into the frame to interfere with the operation of the electrode wire 310 or the anode frame 200, further improving the overall protection system.

[0035] The upper cover plate 160 is bolted to the support frame 100, creating a lateral constraint on the longitudinal rods at the top of the support frame 100. This reduces shaking or deformation of the frame top caused by external forces (such as strong winds or minor impacts), indirectly improving the stability of the entire support frame 100. Furthermore, the integrated, adaptable design eliminates misalignment or gaps between the traditional irregularly shaped cover plate and the frame and protective plate 150, giving the top of the haze removal screen a more uniform and organized appearance. This improves the visual harmony of the device, especially in outdoor installations, and prevents the cluttered top structure from affecting the surrounding aesthetics.

[0036] See also Figure 6 The adjustment component includes an adjusting screw, the upper end of the adjusting screw is rotatably connected to the lower end of the electrode wire 310, and the lower end of the adjusting screw is rotatably connected to the lower end of the cathode frame 300, and the adjusting screw and the electrode wire 310 are coaxial. The design of the adjusting screw being coaxial with the electrode wire 310 ensures that the adjustment force is completely transmitted along the axial direction of the electrode wire 310, avoiding the lateral force component that may be generated by the non-coaxial structure. The coaxial adjustment allows the staff to directly and evenly change the tension of the electrode wire 310 by rotating the screw, accurately control the electrode wire 310 to be in the best working state, and avoid functional abnormalities caused by excessive or insufficient adjustment. At the same time, the rotating connection at both ends of the screw retains the flexibility of adjustment, and can fix the axial position of the electrode wire 310 after the adjustment is completed, reduce the loosening of the screw caused by equipment vibration and temperature changes, and maintain the tension stability of the electrode wire 310 for a long time.

[0037] Based on the same inventive concept, the present invention also provides a construction method for a haze removal screen, comprising the following steps: S1: Preparation before construction: clear the debris in the construction area and level the ground, check the specifications and quantity of each component of the haze removal screen, check the integrity of the components, and prepare construction tools and equipment; S2: Install the support frame 100. Determine the installation position and height of the support frame 100 by positioning and laying out the lines according to the design drawings. Place the support frame 100 according to the laid-out position and adjust its verticality and horizontality before securing it. Check the position, flatness, and strength of the support platforms 110 arranged longitudinally on the support frame 100. S3: Install the cathode frame 300 by connecting the lower end of the insulator string 130 to the support platform 110 and the upper end of the insulator string 130 to both sides of the cathode frame 300. Connect the outwardly extending connecting portions 320 and adjust the position and verticality of the cathode frame 300. S4: Installing and adjusting the electrode wires 310. Arrange multiple electrode wires 310 in the cathode frame 300 according to the designed intervals. Connect the upper ends of the electrode wires 310 to the top of the cathode frame 300, and install adjustment components at the lower ends to adjust the axial tightness of the electrode wires 310 to a suitable tension state. S5: Install the anode frames 200. Install the wire mesh 210 inside the anode frames 200 and ensure that it is firm and flat. Place two anode frames 200 in parallel and spaced apart between adjacent support frames 100. Connect the support frames 100 on the same side axially and horizontally using the connecting bolts 220 symmetrically arranged on both sides of the anode frames 200. Adjust the position and levelness of the anode frames 200. S6: Overall debugging and inspection, comprehensively check the correctness of installation and firmness of connection of each component, detect the insulation performance between the cathode frame 300 and the support frame 100 and the electrical connection status of each component, start the operation system for trial operation and observe the operation status.

[0038] The beneficial effect of the construction method of the haze-removing screen provided by the present invention is that, compared with the existing technology, the pre-construction preparation steps clearly require the removal of debris and leveling of the ground, while also checking the specifications, quantity and integrity of components and preparing tools and equipment. This step can eliminate interference with the construction environment and hidden dangers of components in advance, avoid construction interruptions caused by missing tools or component problems, lay the foundation for the smooth progress of subsequent construction, and improve overall construction efficiency. The installation of the support frame 100 emphasizes positioning and laying out according to the design drawings, adjusting the verticality and horizontality, and then fixing it. The position, flatness, and strength of the support platform 110 are checked to ensure that the support frame 100, as the foundation of the overall structure, is accurately installed and the load-bearing capacity meets the standards, avoiding deviations in the installation of subsequent components due to frame tilt or unstable support platform 110. During cathode frame 300 installation, the support platform 110 and cathode frame 300 are connected via insulator strings 130, and their position and verticality are adjusted. During anode frame 200 installation, the front-to-back parallel spacing is determined, and the horizontal connection and leveling are adjusted using connecting bolts 220. These three steps collaboratively ensure the relative positioning accuracy of the cathode frame 300, anode frame 200, and support frame 100, providing the structural prerequisites for the subsequent functional performance of the electrode wire 310 and wire mesh 210, and reducing the loss of haze removal efficiency caused by misaligned installation. During the installation and adjustment of the electrode wire 310, the tension of the electrode wire 310 is adjusted using an adjustment assembly, eliminating the need for additional structural disassembly. This allows for simple operation and precise control of the tension of the electrode wire 310, ensuring it is in optimal working condition. During anode frame 200 installation, the wire mesh 210 is first secured within the frame before the entire assembly is connected. This avoids the space constraints of installing the frame first and then the mesh, reducing operational complexity. Furthermore, the horizontal connection with connecting bolts 220 also facilitates subsequent maintenance. The overall debugging and inspection steps cover the correctness of component installation, connection firmness, insulation performance, electrical connection status, and trial operation observation. Multi-dimensional testing can comprehensively identify installation hazards.

The construction method of the haze removal screen provided by the present invention not only ensures construction quality and efficiency through step-by-step control, precise adjustment, and comprehensive testing, but also provides guarantees for the long-term reliable operation of the equipment, effectively reducing construction and subsequent operation and maintenance costs.

[0039] After step S5, depending on the end or middle position of the support frame 100 in the haze removal screen, the protective plates 150 are wrapped around the front and rear facades and the outer facades of the support frame 100, or only the front and rear facades. An upper cover plate 160 is installed on the top of the support frame 100, which is compatible with the cross-sectional shape of the combined support frame 100 and protective plates 150. The end support frame 100 forms a closed-loop protection loop through the three-sided protective plates 150 and the adaptive upper cover plate 160. The middle support frame 100 is covered with the front and rear protective plates 150 and the adaptive upper cover plate 160 to achieve key area coverage, ultimately building a full-range protection system from the sides to the top of the frame. This design not only prevents external rain, wind, sand, and debris from infiltrating into the support frame 100 from the sides or top, preventing components such as the support platform 110 and insulator string 130 from rusting and degrading insulation performance due to foreign matter accumulation or environmental erosion, but also enhances the overall sealing and stability of the support frame 100 through the adaptive structure, providing a guarantee for the long-term and reliable operation of the core components of the haze removal screen.

[0040] If the electrode wire 310 becomes loose or broken, remove the non-top connecting bolts 220 on both sides of any anode frame 200, and rotate the anode frame 200 outward with the connecting bolts 220 on the top of both sides of the anode frame 200 as the rotation axis; adjust the loose electrode wire 310 by adjusting the assembly so that its axial tightness reaches a suitable tensioning state; or remove the connection between the broken electrode wire 310 and the top and bottom of the cathode frame 300, reinstall a new electrode wire 310, first install the upper end of the electrode wire 310, then install the lower end of the electrode wire 310, and adjust the axial tightness of the electrode wire 310 to a suitable tensioning state by adjusting the assembly; after the electrode wire 310 is tightened or replaced, rotate the anode frame 200 inward with the connecting bolts 220 on the top of both sides of the anode frame 200 as the rotation axis, and complete the installation of the non-top connecting bolts 220 on both sides of the anode frame 200 from top to bottom.

[0041] Specifically, the staff does not need to dismantle the overall frame of the haze removal screen. They only need to remove the non-top connecting bolts 220 on both sides of any anode frame 200, and use the top connecting bolts 220 on both sides as the rotating axis to rotate the anode frame 200 outward to open it, so as to quickly expose the internal cathode frame 300 and the electrode wire 310, avoiding the problems of complex operation and time-consuming due to overall disassembly in traditional solutions.

[0042] In response to different fault scenarios, the process design further simplifies the operation. If the electrode wire 310 is loose, the axial tightness of the electrode wire 310 can be adjusted to the appropriate tension state directly through the adjustment component, without the need to disassemble the electrode wire 310 body. If the electrode wire 310 is broken, it is only necessary to remove the connection between the broken electrode wire 310 and the top and bottom of the cathode frame 300, install the new electrode wire 310 in the order of installing the upper end first and the lower end later, and then fine-tune the tension by adjusting the component. After the maintenance is completed, the anode frame 200 is rotated inward and reset using the top connection bolt 220 as the rotation axis, and then the non-top connection bolts 220 on both sides are installed in sequence from top to bottom. This can not only ensure that the anode frame 200 is firmly connected to the support frame 100 and the horizontality meets the standard, but also quickly restore the overall structural stability of the equipment, significantly shortening maintenance time and reducing the impact on the normal operation of the haze removal screen.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
