Description

Technical Field

[0001] This utility model relates to the technical field of installation structures, and in particular to an installation structure for a packing grid in a packed tower. Background Technology

[0002] Packed towers are a type of gas-liquid mass transfer equipment widely used in chemical, environmental protection, and petrochemical industries. Their core principle is to provide sufficient contact area between the gas and liquid phases by filling the tower with specific packing material, thereby promoting mass transfer between the two phases.

[0003] The packing grid of a packed tower is a key internal structure, usually installed inside the tower to support and fix the packing layer, ensuring that the packing remains stably and uniformly distributed within the tower, thereby optimizing the contact and mass transfer process between the gas and liquid phases.

[0004] Existing bar screens are mostly installed in a fixed manner, using hoisting and welding equipment to send installation workers and bar screen components into the tower for installation. While this fixed installation method ensures structural stability, the height and position of the bar screen cannot be adjusted after installation. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] Currently, existing packing grates are mostly installed in a fixed manner, using hoisting and welding equipment to send installation workers and grating components into the tower for installation. While this fixed installation method ensures structural stability, the height and position of the grating cannot be adjusted after installation.

[0028] like Figure 1-6As shown, a packing grid installation structure for a packed tower includes a packed tower body 1. The structure is characterized by a base 101 fixedly connected to the bottom of the packed tower body 1, an exhaust port 102 at the top of the packed tower body 1, a sprayer 103 inside the packed tower body 1, two first mounting blocks 4 fixedly connected inside the packed tower body 1, a fixing groove 401 at the top of the first mounting blocks 4, a connecting block 403 fitted inside the fixing groove 401, cylinders 404 fixedly connected to both sides of the connecting blocks 403, a spring 405 inside the cylinders 404, a telescopic block 406 fixedly connected to one end of the spring 405, a grid frame 2 fixedly connected to the top of the connecting blocks 403, movable openings 3 on both sides of the grid frame 2, a central shaft 301 fixedly connected inside the movable openings 3, a torsion spring 302 rotatably connected to the surface of the central shaft 301, a folding block 303 fixedly connected to the torsion arm end of the torsion spring 302, and a packing body 104 fitted to the top of the grid frame 2.

[0029] The packed tower body 1 serves as the foundation support for the entire device, with its bottom fixed to the ground by a base 101 to ensure overall stability. An exhaust port 102 is located at the top to discharge the treated gas from inside the tower. An internally installed sprayer 103 is responsible for uniformly spraying liquid onto the packed tower body 104, which provides a large surface area to promote sufficient contact and mass transfer between the gas and liquid phases.

[0030] When the position of the packing body 104 needs to be adjusted, first open the cover plate at the top of the packing tower body 1 and remove the packing body 104. Then, use a crane to lower the hook on the crane to a suitable height, connect the hook to the lifting ring 204 at the top of the grid frame 2, and lift it upwards. At this time, the telescopic block 406 and the connecting block 403 slide out from the first mounting block 4. The grid frame 2 then moves to the preset position inside the packing tower body 1 as needed. After the grid frame 2 moves to the required position, rotate the grid frame 2 ninety degrees. Align the movable opening 3 with the second mounting block 402, and then continue to pull the grid frame 2 upward. The folding block 303 contacts the second mounting block 402. At this time, the central shaft 301 in the movable opening 3 serves as the rotation fulcrum, and the torsion spring 302 provides elastic restoring force, causing the folding block 303 to fold. At this time, the grid frame 2 passes through the second mounting block 402 and is located above it. Then, rotate the grid frame 2 ninety degrees in the opposite direction so that the connecting block 403 is located on the second mounting block 402. Then, lower the grid frame 2 so that the connecting block 403 fits into the fixing groove 401.

[0031] By combining the folding block 303 with the elastic mechanism of the central shaft 301 and the torsion spring 302, the grid frame 2 can automatically fold and pass through the encountered mounting block when it comes into contact with the first mounting block 4 or the second mounting block 402. Then, by rotating the grid frame 2 in the opposite direction, the connecting block 403 is connected to the fixing groove 401. This ensures both the flexibility of movement and the structural stability and sealing after installation.

[0032] The entire grid frame 2 is hoisted by using the lifting ring 204 in conjunction with the hook, and quick release is achieved by using the telescopic block 406 in conjunction with the connecting block 403. Combined with the automatic reset function of the folding block 303 and the torsion spring 302, the grid frame 2 can be quickly switched between different installation blocks. This design not only realizes the flexible adjustment of the height position of the packing body 104, but also meets different process requirements.

[0033] Furthermore, the grid frame 2 is internally fixedly connected with grid bars 202, the middle part of the grid bars 202 is fixedly connected with reinforcing ribs 201, and the outer ring of the grid frame 2 is fixedly connected with grid rings 203.

[0034] The grid bars 202 inside the grid frame 2 form a supporting mesh, the reinforcing ribs 201 enhance the overall structural strength, and the grid ring 203 provides edge support as an outer frame. The grid bars 202 are evenly distributed to ensure stable support and gas-liquid flow of the packing body 104.

[0035] Furthermore, the telescopic block 406 is snapped into the inside of the cylinder 404, and a hemisphere 407 is fixedly connected to one end of the telescopic block 406, with the hemisphere 407 fitting against the fixing groove 401.

[0036] Springs 405 are installed inside the cylinders 404 on both sides of the connecting block 403. The springs 405 push the telescopic block 406 to extend outward, so that the hemisphere 407 is tightly attached to the inner wall of the fixing groove 401. The elastic force of the springs 405 ensures that the hemisphere 407 and the fixing groove 401 maintain close contact, forming an elastic connection.

[0037] The elastic connection design of spring 405 and telescopic block 406 can compensate for installation errors, and the spherical contact of hemispherical ball 407 reduces friction and facilitates installation and adjustment.

[0038] Furthermore, the inner wall of the grille ring 203 is a smooth curved surface and is inclined inward.

[0039] This allows the liquid on the inner wall of the packed tower body 1 to be guided inward and converge towards the center, thereby reducing wall flow.

[0040] Furthermore, a lifting ring 204 is fixedly connected to the top of the grid frame 2, and two second mounting blocks 402 are provided on the top of the first mounting block 4. The two second mounting blocks 402 are fixedly connected to the inner wall of the packing tower body 1, and the second mounting blocks 402 and the first mounting block 4 are staggered.

[0041] The first mounting block 4 and the second mounting block 402 are staggered to form multi-point support, which facilitates the adjustment of the installation position of the grid frame 2 and ensures the stable installation of the grid frame 2.

[0042] Furthermore, the area of ​​the folding block 303 is larger than the areas of the second mounting block 402 and the first mounting block 4.

[0043] This allows the folding block 303 to completely cover the mounting block when in motion, facilitating the movement of the grid frame 2.

[0044] Furthermore, the reinforcing ribs 201 are arranged in a cross pattern.

[0045] The reinforcing ribs 201 are arranged in a cross shape in the middle of the grid bars 202. This structure can effectively distribute and bear the forces from all directions, improving the overall strength and stability of the grid frame.

[0046] Furthermore, the working surface of the folding block 303 is provided with a wear-resistant coating, which is a metal carbide to improve the wear resistance of the material surface.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
