Description

Technical Field

[0001] This utility model relates to the field of chemical separation equipment technology, and in particular to a packing tower grid installation structure. Background Technology

[0002] In current chemical process industries, packed towers are widely used as key mass transfer and separation equipment in various gas-liquid contact processes. Under countercurrent gas-liquid two-phase operation, the grid installation structure of conventional packed towers directly affects the stability of the packing layer. Existing packed tower grids mostly use welding or bolting for fixing, which has limited installation accuracy and insufficient adjustment range. Traditional grid structures are difficult to adapt to changes in different packing types and are prone to grid deformation under fluctuating operating loads. Current fixing measures often rely on increasing the number of support beams or improving the connecting plate structure, which is complex to install and requires high manufacturing precision. Furthermore, conventional grid structures struggle to achieve coordinated control of rapid assembly / disassembly and stable support, maintaining the designed support effect only under specific operating conditions. Therefore, it is necessary to develop a new packed tower grid installation structure to solve the technical problems of insufficient grid installation adaptability and poor support stability leading to decreased packing layer stability in existing technologies. Utility Model Content

[0003] The purpose of this utility model is to provide a packing tower grid installation structure that solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a packed tower grid installation structure.

[0005] The system comprises tower body units, grid units, and connecting units. The tower body units adopt a cylindrical structure. The grid units are installed inside the tower body units via support beams. The connecting units are fixed to the inner wall of the tower body units. Each tower body unit includes an outer tower wall and an inner support ring. The outer tower wall is made of stainless steel. The inner support ring is fixed to the inner wall of the tower body unit by welding. Each grid unit includes grid plates, positioning slots, and reinforcing ribs. The grid plates are installed on the surface of the support beams via clips. Positioning slots are located at the edges of the grid plates. Reinforcing ribs are welded to the bottom surface of the grid plates. Each connecting unit includes connecting bolts, locking washers, and lock nuts. The connecting bolts pass through the support beams and the inner support ring. Locking washers are located at the bolt heads. Lock nuts are screwed onto the bolt ends.

[0006] During equipment operation, the grating plates bear the weight of the filler layer, and positioning slots ensure precise placement of the grating plates. Reinforcing ribs enhance the rigidity of the grating structure, while connecting bolts and anti-loosening nuts work together to provide a stable connection. The inner support ring evenly distributes the load to the tower body units, ensuring overall structural stability.

[0007] As a further improvement, the grating panel features a zoned support structure. This structure includes a central support zone and edge support zones. The central support zone uses a diamond-shaped mesh. The edge support zones are fixed to the perimeter of the central support zone via connecting plates. This zoned support structure provides differentiated support for different areas, improving the uniformity of load distribution.

[0008] As a further improvement, the positioning slot is equipped with a flexible positioning mechanism. The flexible positioning mechanism includes a positioning spring, a limiting block, and an adjusting screw. The positioning spring is located at the bottom of the slot. The limiting block is mounted inside the slot via a slide rail. The adjusting screw passes through the side wall of the slot. The flexible positioning mechanism compensates for installation gaps and maintains the positioning accuracy of the grating plate.

[0009] As a further improvement, the tower unit incorporates a load transfer structure. This structure includes a load-bearing ring, distribution beams, and reinforcing ribs. The load-bearing ring is welded to the inner wall of the tower unit. The distribution beams are arranged radially on the surface of the load-bearing ring. The reinforcing ribs are vertically positioned between the distribution beams. This load transfer structure optimizes stress distribution and reduces localized deformation.

[0010] As a further improvement, the connecting unit is equipped with a quick-locking structure. The quick-locking structure includes a locking handle, an eccentric wheel, and a clamping block. The locking handle is hinged to the head of the connecting bolt. The eccentric wheel is fixed to the handle's pivot. The clamping block is positioned between the eccentric wheel and the support beam. This quick-locking structure enables rapid assembly and disassembly of the grid unit, improving maintenance efficiency.

[0011] As a further improvement, the grating unit is equipped with an anti-deformation structure. This structure includes cross struts, a buffer pad layer, and stress relief holes. The cross struts are obliquely welded to the bottom surface of the grating. The buffer pad layer is adhered to the contact surface between the grating and the support beam. The stress relief holes are located in areas of stress concentration within the grating. This anti-deformation structure enhances the grating's resistance to deformation and extends its service life.

[0012] As a further improvement, the tower unit is equipped with a quick-access maintenance structure. This structure includes a manhole, observation window, and lifting ring. The manhole is located on the side wall of the tower unit. The observation window is fitted into the manhole cover. The lifting ring is welded to the top of the tower unit. This quick-access maintenance structure facilitates internal inspection and component replacement, reducing maintenance complexity.

[0013] In summary, the packing tower grid installation structure of this invention achieves high-precision positioning and stable load-bearing through a synergistic design of zoned support and quick locking. Its elastic positioning and anti-deformation structure significantly improve the adaptability and reliability of the device, while load transfer and rapid maintenance further optimize the ease of maintenance and long-term operational stability. This effectively solves the technical problem of decreased packing layer stability caused by insufficient adaptability and poor support stability in traditional grid installation structures.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Example 1

[0022] Please see Figures 1 to 4 This utility model provides a packed tower grid installation structure, the overall structure of which mainly includes a tower body unit 1, a grid unit 2, and a connecting unit 3. The tower body unit 1 serves as the main container and external protection of the packed tower grid installation structure, providing internal space and supporting internal components; the grid unit 2 is the core component that carries the packing layer (not shown) and allows gas and liquid to pass through, aiming to maintain the stability of the packing layer; the connecting unit 3 is responsible for firmly and detachably fixing the grid unit 2 inside the tower body unit 1.

[0023] Specifically, the tower unit 1 adopts a cylindrical structure, with its overall external dimensions typically ranging from approximately 800 mm to 4,000 mm in diameter and from approximately 3,000 mm to 10,000 mm in height, designed to provide an installation environment compatible with the main body of an industrial packed tower (not shown). The tower unit 1 consists of an outer tower wall 4 and an inner support ring 5. The top of the tower unit 1 is equipped with a gas inlet and a liquid distributor (both not shown), while the bottom is equipped with a gas outlet and a liquid collector (both not shown). Its upper and lower end faces can be flanged or welded to the corresponding process pipelines and structures of the packed tower.

[0024] The outer tower wall 4 is made of stainless steel. Its main body is constructed from SUS304 or SUS316L food-grade stainless steel plates with a thickness of approximately six to twenty millimeters, manufactured through precision rolling, welding, and surface polishing or pickling passivation processes. This results in extremely high strength, excellent corrosion resistance, and good adaptability to high-temperature and high-pressure environments. The outer tower wall 4 has a cylindrical structure, its height matching the height of the packing section of the packed tower (not shown), and is designed according to actual process requirements. The inner wall of the outer tower wall 4 has reserved positions for welding the inner support ring 5; these positions are typically precisely positioned and machined. As the external pressure-bearing and protective structure of the packed tower grid installation structure, the outer tower wall 4 ensures the structural integrity and safety of the unit during chemical processes.

[0025] The inner support ring 5 is made of the same stainless steel as the outer tower wall 4. Its main body is manufactured from SUS304 or SUS316L stainless steel plates with a thickness of approximately 10-20 mm and a width of approximately 50-100 mm through bending and precision welding. The inner support ring 5 has a ring-shaped structure, with its outer diameter closely matching the inner diameter of the outer tower wall 4. It is firmly fixed to the inner wall of the tower unit 1 by ring welding. It is typically located below the packing layer (not shown) and supports the grid unit 2, for example, at a distance of 100-300 mm from the bottom of the packed tower or the next layer of packing support plate (not shown), aiming to provide a horizontal and stable mounting surface for the connecting unit 3. The surface of the inner support ring 5 is usually smoothed to ensure the installation accuracy of the connecting unit 3 and the support beam (not shown). The inner support ring 5 bears the weight of the grid unit 2, as well as the static and operational loads of the packing layer (not shown) above it, and evenly transfers these loads to the outer tower wall 4, thereby ensuring the overall stability of the internal structure of the packed tower.

[0026] The grid unit 2 is installed inside the tower body unit 1 via a support beam (not shown, made of stainless steel angle steel, channel steel, or plate, and fixed to the surface of the inner support ring 5 by bolts or welding). The main body of the support beam is a ring or multi-point beam structure with high strength, sufficient to bear the weight of the grid plate 6 and the load of the packing layer, while ensuring the uniformity of force transmission. The grid unit 2 is the core system in the packed tower grid installation structure that bears the packing layer and allows gas and liquid to pass through. It includes a grid plate 6, several positioning slots 7, and several reinforcing ribs 8.

[0027] The grating plate 6 is made of stainless steel, with its main body constructed from SUS304 or SUS316L stainless steel plates approximately 5 to 10 millimeters thick through laser cutting, stamping, and welding processes. The grating plate 6 has a circular or polygonal mesh structure, with its outer diameter slightly smaller than the inner diameter of the tower unit 1, leaving a gap of approximately 5 to 10 millimeters between it and the inner wall of the tower. The mesh size is typically 20 millimeters x 20 millimeters to 50 millimeters x 50 millimeters to allow free passage of gas and liquid while providing support for the packing layer (not shown). The grating plate 6 is installed on the surface of the support beam (not shown) using several stainless steel clips (e.g., elastic claws or U-shaped clips). These clips engage with slots or holes on the support beam to achieve rapid positioning and installation of the grating plate 6. The clip connection allows for some thermal expansion displacement while ensuring a secure connection. The edges of the mesh openings in the grating plate 6 are typically chamfered to prevent scratching or damage to the packing.

[0028] The positioning groove 7 is made of stainless steel and has a U-shaped or L-shaped slot structure. Its depth is approximately 10 to 20 millimeters, and its width is approximately 5 to 10 millimeters. The positioning groove 7 is located at the edge of the grating plate 6, typically evenly distributed along its perimeter, and engages with corresponding positioning protrusions (not shown) on the support beam (not shown) or inner support ring 5. The inner wall of the positioning groove 7 is usually precision-machined to ensure a tight fit with the mating parts. The purpose of the positioning groove 7 is to ensure that the grating plate 6 is accurately positioned during installation, preventing horizontal displacement or rotation due to airflow impact or packing layer vibration during operation, thereby ensuring the stability and uniform distribution of the packing layer (not shown).

[0029] The reinforcing ribs 8 are made of stainless steel flat bars or angle bars (e.g., SUS304 or SUS316L), with a strip-shaped structure, a thickness of approximately three to five millimeters, and a width of approximately twenty to fifty millimeters. The reinforcing ribs 8 are firmly welded to the bottom surface of the grating plate 6, typically in a cross shape, radially, or annularly distributed, with their length matching the dimensions of the grating plate 6. The welding process for the reinforcing ribs 8 employs continuous or intermittent welding to ensure weld strength and reduce thermal deformation. The reinforcing ribs 8 significantly improve the structural rigidity and load-bearing capacity of the grating plate 6, preventing local deformation or overall bending of the grating plate 6 when bearing the weight of the filler layer (not shown) and operating loads, thereby ensuring the flatness and stability of the filler layer support.

[0030] The connecting unit 3 is fixed to the inner wall of the tower body unit 1, usually located above the inner support ring 5, and is connected to the support beam (not shown) by bolts. The connecting unit 3 is the core system in the packed tower grid installation structure that realizes a firm connection between the grid unit 2 and the tower body unit 1. It includes several connecting bolts 9, several locking washers 10, and several anti-loosening nuts 11.

[0031] The connecting bolt 9 is made of high-strength stainless steel (e.g., A2-70 or A4-80 grade), with a threaded rod-like body, a diameter of approximately 16 to 24 mm, and a length of approximately 50 to 150 mm. The connecting bolt 9 vertically penetrates the corresponding through holes of the support beam (not shown) and the inner support ring 5, and its threaded section mates with the lock nut 11. Its head is typically hexagonal or square. The surface of the connecting bolt 9 is usually acid-etched and passivated to enhance corrosion resistance. The function of the connecting bolt 9 is to provide vertical connecting force, firmly anchoring the grid unit 2 to the tower unit 1.

[0032] The locking washer 10 is made of high-strength stainless steel (e.g., SUS304 or SUS316L). Its main body is a circular flat washer or spring washer, with its inner diameter tightly fitting the outer diameter of the connecting bolt 9. The outer diameter is approximately two to three times the diameter of the connecting bolt 9, and its thickness is approximately two to five millimeters. The locking washer 10 is positioned between the head of the connecting bolt 9 and the contact surface of the support beam (not shown). The function of the locking washer 10 is to increase the contact area between the head of the connecting bolt 9 and the support beam (not shown), evenly distribute the bolt preload, and provide additional frictional resistance or elastic deformation, thereby preventing the connecting bolt 9 from loosening due to vibration.

[0033] The anti-loosening nut 11 is made of high-strength stainless steel (e.g., A2-70 or A4-80 grade), and its main body is hexagonal or round. Its thread specification matches the thread section of the connecting bolt 9. The anti-loosening nut 11 is tightened by screwing onto the end of the connecting bolt 9, typically using double-nut locking, nylon self-locking nuts, or slotted nuts with cotter pins (not shown). The anti-loosening nut 11 provides additional locking force after the connecting bolt 9 is tightened, effectively preventing the connecting bolt 9 from loosening under long-term vibration, temperature cycling, and operating load changes in the packed tower (not shown), thereby ensuring the long-term stability and reliability of the connection.

[0034] During equipment operation, the grating plate 6 bears the weight of the packing layer (not shown) above it through its mesh structure, allowing gas and liquid to undergo normal mass transfer within the packed tower (not shown). The reinforcing ribs 8 are firmly welded to the bottom surface of the grating plate 6, significantly improving its structural rigidity and load-bearing capacity, ensuring that the grating plate 6 will not bend or deform under heavy loads. The grating plate 6 is installed on the surface of the support beam (not shown) using stainless steel clips, ensuring a secure and reliable connection while also accommodating certain thermal expansion. The positioning slots 7 are located at the edge of the grating plate 6, tightly engaging with corresponding positioning protrusions (not shown) on the support beam (not shown) or the inner support ring 5, ensuring that the grating plate 6 can be precisely positioned when impacted by airflow or vibrating in the packing layer within the tower, preventing horizontal displacement. The connecting bolts 9 vertically penetrate the support beam (not shown) and the inner support ring 5, firmly fixing the grating unit 2 (via the support beam) to the inner support ring 5. The locking washers 10 are located below the heads of the connecting bolts 9, increasing the contact area and evenly distributing the preload. The anti-loosening nut 11 is screwed onto the end of the connecting bolt 9. Through its anti-loosening mechanism (e.g., locking or self-locking), it effectively prevents the connecting bolt 9 from loosening under long-term vibration, thus providing a stable and reliable connection. The inner support ring 5 evenly transfers the weight of the packing layer (not shown) and the operating load carried by the grid unit 2 to the outer tower wall 4, and finally distributes it throughout the entire tower body unit 1 structure, ensuring the overall stability of the entire packed tower structure. Through the above structure and workflow, this packed tower grid installation structure can provide stable and uniform support for the packing layer, ensuring the safe and efficient operation of the packed tower under various working conditions.

[0035] Example 2

[0036] In another embodiment of this utility model, the grating plate 6 is provided with a zoned support structure to achieve differentiated support in different areas and improve the uniformity of load distribution. Its structure is basically the same as in Embodiment 1, and will not be described again here. Specifically, the zoned support structure includes a central support area 12 and several edge support areas 13. Please refer to... Figure 2The central support area 12 is made of stainless steel and has a diamond-shaped mesh structure. Its outer diameter is approximately 50% to 70% of the diameter of the grating plate 6, and its thickness is approximately 5 to 10 millimeters. The mesh size is typically 20 mm x 20 mm to 40 mm x 40 mm. Located in the central area of ​​the grating plate 6, the central support area 12 serves as the main load-bearing area, directly supporting the packing layer (not shown) in the central region of the packed tower (not shown), and typically bears the maximum packing load. The edge support area 13 is also made of stainless steel and has a ring-shaped or fan-shaped mesh structure. Its width is approximately 50 to 100 millimeters, and its thickness is approximately 4 to 8 millimeters. The mesh size is similar to or slightly larger than that of the central support area 12. The edge support area 13 is fixed to the periphery of the central support area 12 by several connecting plates (made of stainless steel, approximately 3 to 5 millimeters thick and 50 to 100 millimeters long), evenly distributed radially or in a ring, with an adjustable gap between them. The connecting plate connects the central support area 12 and the edge support area 13 via bolts or welding, allowing the edge support area 13 to undergo minor displacement or angular adjustment relative to the central support area 12 within a certain range to accommodate local settlement or thermal expansion of the packing layer (not shown). The partitioned support structure enables the grid plate 6 to provide differentiated support based on potential radial density variations, operating load differences, or local settlement within the packing layer of the packed tower (not shown). By optimizing the structural design and connection method of the central support area 12 and the edge support area 13, the load distribution of the packing layer across the entire cross-section can be more precisely controlled. This structure significantly improves the uniformity of load distribution on the packing layer by the grid plate 6, effectively solving the problem of uneven load distribution in traditional grid structures, thereby further optimizing the mass transfer efficiency and operational stability of the packed tower.

[0037] Example 3

[0038] In another embodiment of this utility model, the positioning slot 7 is provided with an elastic positioning mechanism to compensate for installation gaps and maintain the positioning accuracy of the grille plate. Its structure is basically the same as in Embodiment 1, and will not be described again here. Specifically, the elastic positioning mechanism includes several positioning springs 14, several limiting blocks 15, and several adjusting screws 16. Please refer to... Figure 2The positioning spring 14 is a high-elasticity stainless steel compression spring (e.g., SUS304 or SUS316L), with a wire diameter of approximately two to four millimeters, a free height of approximately ten to twenty millimeters, and an elastic coefficient of approximately ten to thirty Newtons per millimeter. The positioning spring 14 is located at the bottom of the positioning slot 7 and is installed between the bottom of the slot and the grid plate 6 (not shown) via a dedicated spring seat (made of stainless steel), providing a continuous upward elastic support force. The limiting block 15 is made of wear-resistant engineering plastic (e.g., UHMW-PE, POM) or self-lubricating copper alloy, with a rectangular or cylindrical structure whose dimensions match the internal space of the positioning slot 7. The limiting block 15 is installed inside the positioning slot 7 via a slide rail (opened on the side wall of the positioning slot 7), allowing the limiting block 15 to make minor displacements along the slide rail. The adjusting screw 16 is a high-strength stainless steel screw (e.g., M6 or M8), with a thread length of approximately twenty to forty millimeters. The adjusting screw 16 horizontally penetrates the side wall of the positioning slot 7 and engages with a threaded hole (not shown) inside the positioning slot 7 via a threaded connection. Its head typically has an internal or external hexagonal head for easy adjustment. The end of the adjusting screw 16 usually contacts the limiting block 15. By tightening or loosening the adjusting screw 16, the initial position of the limiting block 15 and the lateral clamping force on the grating plate 6 can be precisely adjusted. The elastic positioning mechanism provides elastic support through the positioning spring 14, lateral limiting through the limiting block 15, and precise adjustment through the adjusting screw 16. This structure compensates for the installation gap between the grating plate 6 and the support beam (not shown) or the inner support ring 5, and absorbs the horizontal impact force caused by the vibration of the filler layer (not shown). This structure ensures that the grating plate 6 maintains accurate positioning under any working condition, avoiding horizontal swaying of the grating plate 6 due to excessive gaps, thereby significantly improving the positioning accuracy and long-term stability of the grating plate 6.

[0039] Example 4

[0040] In another embodiment of this utility model, the tower unit 1 is provided with a load transfer structure to optimize stress distribution and reduce local deformation. Its structure is basically the same as in Embodiment 1, and will not be described again here. Specifically, the load transfer structure includes a load-bearing ring 17, several distribution beams 18, and several reinforcing ribs 19. Please refer to [link to relevant documentation]. Figure 1The load-bearing ring 17 is made of the same stainless steel material as the outer tower wall 4. Its main body is manufactured from SUS304 or SUS316L stainless steel plates with a thickness of approximately 15 to 25 mm and a width of approximately 80 to 150 mm through bending and precision welding processes. The load-bearing ring 17 has a ring-shaped structure, with its outer diameter closely matching the inner diameter of the outer tower wall 4. It is firmly welded to the inner wall of the tower unit 1 using a ring-shaped welding method. It is typically located below the inner support ring 5 and bears the load of the packing layer (not shown) transmitted by the inner support ring 5. The surface of the load-bearing ring 17 is usually smoothed to ensure the installation accuracy of the distribution beam 18. The function of the load-bearing ring 17 is to provide a ring-shaped secondary support structure, evenly distributing the locally concentrated load transmitted by the inner support ring 5 (not shown) to a larger area of ​​the outer tower wall 4. The distribution beams 18 are made of stainless steel profiles (e.g., I-beams, H-beams, or channel steel), with a main cross-sectional dimension of approximately 80 mm x 100 mm to 150 mm x 200 mm, and a length matching the inner diameter of the tower unit 1. The distribution beams 18 are radially arranged on the surface of the load-bearing ring 17, typically in groups of eight to sixteen, connected by welding or high-strength bolts. One end of each beam is connected to the center of the tower unit 1 (e.g., via a central support plate, not shown), and the other end is connected to the load-bearing ring 17. The function of the distribution beams 18 is to further subdivide the circumferential load on the load-bearing ring 17 and transfer it to the reinforcing ribs 19. The reinforcing ribs 19 are made of stainless steel plates (e.g., SUS304 or SUS316L), with a rectangular plate shape, a thickness of approximately 6 mm to 10 mm, and a height of approximately 100 mm to 200 mm. The reinforcing ribs 19 are vertically installed between the distribution beams 18 by welding, and are welded between the inner wall of the outer tower wall 4 and the load-bearing ring 17, typically evenly distributed along the axial direction of the tower unit 1. The reinforcing ribs 19 enhance the local stiffness of the outer tower wall 4, uniformly distributing the load transmitted by the distribution beams 18 to a larger axial area of ​​the outer tower wall 4. The load transfer structure, through the synergistic effect of the load-bearing ring 17, the distribution beams 18, and the reinforcing ribs 19, gradually and evenly transfers the load generated by the grid unit 2 and the packing layer above it (not shown) from a local area to a larger area of ​​the tower unit 1. This structure significantly optimizes the stress distribution of the outer tower wall 4, effectively reducing local stress concentration and deformation that may occur in the tower under heavy loads, thereby improving the overall structural stability and service life of the packed tower.

[0041] Example 5

[0042] In another embodiment of this utility model, the connecting unit 3 is provided with a quick-locking structure to enable quick assembly and disassembly of the grille unit 2, improving maintenance efficiency. Its structure is basically the same as in Embodiment 1, and will not be described again here. Specifically, the quick-locking structure includes a locking handle 20, an eccentric wheel 21, and a clamping block 22. Please refer to... Figure 2 The locking handle 20 is made of high-strength stainless steel or engineering plastic (e.g., PA66+GF30), and its main body is lever-shaped or T-shaped, with a length of approximately 100 mm to 200 mm. The locking handle 20 is hinged to the head of the connecting bolt 9 via a precision hinge (made of stainless steel, with a pin diameter of approximately 8 mm to 12 mm), allowing the handle to rotate approximately 90 to 180 degrees vertically. The surface of the locking handle 20 is typically treated with an anti-slip coating for ease of operation. The locking handle 20 provides an operating interface, driving the eccentric wheel 21 by rotating the handle. The eccentric wheel 21 is made of high-strength stainless steel or hardened alloy steel, and its main body is disc-shaped or elliptical, with a diameter of approximately 30 mm to 50 mm and an eccentricity of approximately 5 mm to 10 mm. The eccentric wheel 21 is securely fixed to the rotating shaft (not shown) of the locking handle 20 via a key connection or interference fit, and rotates synchronously with the handle. The eccentric wheel 21 is configured to convert the rotation of the locking handle 20 into a linear clamping force of the clamping block 22. The clamping block 22 is made of high-strength stainless steel or wear-resistant alloy steel, and its main body is a rectangular block or cylindrical structure, with dimensions of approximately 30 mm x 50 mm to 50 mm x 80 mm. The clamping block 22 is positioned between the eccentric wheel 21 and the support beam (not shown), and its contact surfaces with the eccentric wheel 21 and the support beam (not shown) are typically hardened or have wear-resistant pads. The clamping block 22 is configured to evenly transmit the clamping force generated by the eccentric wheel 21 to the support beam (not shown). After the grid unit 2 is installed in place, the operator rotates the locking handle 20, causing the eccentric wheel 21 to rotate. When the eccentric point of the eccentric wheel 21 acts on the clamping block 22, the clamping block 22 is subjected to a strong downward pressure. This pressure is transmitted to the inner support ring 5 (not shown) through the support beam (not shown), thereby firmly locking the grid unit 2 inside the tower unit 1. The quick-locking structure is designed so that the operating force provided by the locking handle 20 is converted into clamping force through the eccentric wheel 21 and evenly transmitted through the clamping block 22. This structure greatly simplifies the installation and disassembly process of the grid unit 2, allowing the grid unit 2 to be locked and unlocked in a short time without the need for additional wrenches or tools. This structure significantly improves the maintenance efficiency of the packed tower (not shown), and is especially suitable for rapid maintenance operations in field or space-constrained environments.

[0043] Example 6

[0044] In another embodiment of the present utility model, the grid unit 2 is provided with an anti-deformation structure, which is used to enhance the deformation resistance of the grid and prolong the service life. Its structure is basically the same as that of the first embodiment, and will not be repeated here. Specifically, the anti-deformation structure comprises a plurality of cross support rods 23, a plurality of buffer cushions 24, and a plurality of stress relief holes 25. Please refer to Figure 2 , the cross support rods 23 are made of stainless steel round tubes or square tubes (such as SUS304 or SUS316L), with a diameter or side length of about 20 mm to 40 mm, and a wall thickness of about 2 mm to 4 mm. The cross support rods 23 are diagonally welded to the bottom surface of the grid plate 6 by welding, usually distributed in an "X" shape or a "star" shape, and both ends thereof are connected to the reinforcing ribs 8 under the grid plate 6 or a support beam (not shown). The arrangement of the cross support rods 23 functions to form an additional three-dimensional space truss structure, which significantly enhances the overall bending stiffness and torsional stiffness of the grid plate 6, and effectively resists the transverse shear force or uneven load generated by the packing layer (not shown). The buffer cushions 24 are made of high-temperature resistant and corrosion-resistant fluororubber (FKM), ethylene propylene diene monomer rubber (EPDM) or polytetrafluoroethylene (PTFE) material, the main body of which is in the shape of a gasket or a strip, with a thickness of about 3 mm to 8 mm. The buffer cushions 24 are adhered to the contact surface between the grid plate 6 and the support beam (not shown) by a high-performance industrial adhesive, covering the entire contact area. The arrangement of the buffer cushions 24 functions to provide a flexible buffer interface between the grid plate 6 and the support beam (not shown), absorb and disperse the impact force generated by the vibration of the packing layer (not shown), reduce direct friction and wear between metal parts, and compensate for tiny gaps at the same time. The stress relief holes 25 are circular, elliptical or slit-shaped, with a diameter or length of about 5 mm to 20 mm. The stress relief holes 25 are formed in the stress concentration area of the grid plate 6 by laser cutting or stamping processes, for example, at the edges of the mesh holes, near the welding joints between the reinforcing ribs 8 and the grid plate 6. The edges of the stress relief holes 25 are usually rounded to avoid stress concentration. The arrangement of the stress relief holes 25 functions to guide the stress to redistribute along a preset path when the grid plate 6 is under load, effectively reducing local stress concentration, thereby delaying the initiation and propagation of fatigue cracks. The arrangement of the anti-deformation structure functions to enhance the structural stiffness through the cross support rods 23, absorb impact force through the buffer cushions 24, and optimize the stress distribution through the stress relief holes 25. This structure improves the deformation resistance and fatigue life of the grid unit 2 from multiple levels, effectively solves the problem that the traditional grid structure is prone to deformation under long-term operating load fluctuations, thereby prolonging the service life of the grid unit 2 and ensuring the long-term stable operation of the packed tower (not shown).

[0045] Embodiment 7

[0046] In another embodiment of this utility model, the tower unit 1 is provided with a quick-access maintenance structure to facilitate internal inspection and component replacement, reducing maintenance difficulty. Its structure is basically the same as in Embodiment 1, and will not be described again here. Specifically, the quick-access maintenance structure includes a manhole 26, an observation window 27, and a lifting ring 28. Please refer to... Figure 1 The maintenance manhole 26 is made of stainless steel, with a circular or elliptical body, an outer diameter of approximately 400 mm to 600 mm, and a thickness of approximately 10 mm to 20 mm. The maintenance manhole 26 is welded to the side wall of the tower unit 1, typically located above or below the grid unit 2, facilitating personnel access to the tower for inspection and maintenance. The maintenance manhole 26 is usually equipped with a hinged quick-opening manhole cover (not shown), which, when closed, is tightly sealed to the tower unit 1 via a flange connection and a sealing gasket (not shown). The observation window 27 is made of high-strength, corrosion-resistant tempered glass or quartz glass, with a diameter of approximately 100 mm to 200 mm and a thickness of approximately 10 mm to 20 mm. The observation window 27 is fitted into the center of the cover plate (not shown) of the maintenance manhole 26 via threaded clamping or a flange connection, and is equipped with a sealing gasket. The observation window 27 is usually fitted with a protective cover (not shown). The observation window 27 is designed to allow operators to observe the surface condition of the grating plate 6, the flatness of the packing layer (not shown), and whether there is any abnormal liquid accumulation or blockage inside, without opening the manhole, thus achieving non-invasive inspection. The lifting ring 28 is made of high-strength stainless steel (e.g., SUS304 or SUS316L), with a circular or D-shaped ring body, a diameter or side length of approximately 50 to 100 millimeters, and a material cross-sectional diameter of approximately 10 to 20 millimeters. The lifting ring 28 is firmly welded to the top outer wall of the tower unit 1 (usually multiple rings are evenly distributed along the perimeter), and its welding strength meets the lifting requirements of the tower unit 1 and internal components, and has undergone non-destructive testing. The lifting ring 28 provides a safe and reliable lifting point during the installation, maintenance, or overall lifting of the packed tower (not shown), facilitating the use of lifting equipment to lift, position, or replace the tower unit 1 and the internal grating unit 2. The rapid inspection structure provides personnel access through the manhole 26, allows non-intrusive observation through the observation window 27, and provides convenient lifting capabilities through the lifting ring 28. This structure significantly simplifies the internal inspection and maintenance process of the packed tower grid installation structure, shortens maintenance time, reduces on-site maintenance difficulty and labor costs, and improves equipment availability and operational reliability.
