Description

Technical Field

[0001] The invention relates to the technical field of desulfurization absorption towers, and in particular to a turbulent pipe grid support connection structure. Background Art

[0002] In the desulfurization process of modern industry, the dual-zone reaction model of the desulfurization tower based on the turbulent liquid holding zone and the spray absorption zone has been widely used. Among them, the turbulent pipe grid device is arranged in the absorption tower as a key component. The turbulent liquid holding zone formed above it can make SO2 be efficiently removed twice in the turbulent liquid holding zone and the spray absorption zone, which is of great significance for improving the desulfurization efficiency and reducing pollutant emissions.

[0003] The traditional way of fixing the turbulent tube grid assembly is usually to directly fix the turbulent tube grid assembly with the help of the fixing bolts and nuts welded on the support beam inside the desulfurization tower. However, in the actual operation process, this fixing method exposes many problems. Due to the harsh working environment, the turbulent tube grid assembly will continue to be subjected to various impacts during operation. These impacts directly act on the fixing bolts. Over time, it is very easy to cause the bolts to loosen. Once some bolts are loose, a chain reaction will be triggered, which may cause several turbulent tube grid assemblies to loosen as a whole. When this happens, the outer wall of the absorption tower will vibrate violently, which will not only affect the normal operation of the desulfurization tower and reduce the desulfurization effect, but also may damage the overall structure of the desulfurization tower, bringing safety hazards. Moreover, during the operation of the desulfurization tower, it is difficult to directly and effectively eliminate this hidden danger, which brings great challenges to the continuity and stability of industrial production. Therefore, it is urgent to develop a more reliable and stable turbulent tube grid support connection structure to overcome the deficiencies in the existing technology and ensure the efficient and safe operation of the desulfurization tower.

[0007] Furthermore, a connecting plate is welded to one side of the two symmetrically installed mounting slot frames away from the support beam.

[0008] Furthermore, the bottom end of the screw rod is welded to the top end of the support beam.

[0025] Example 1

[0026] like Figure 1-Figure 4 As shown, the present invention provides a turbulence tube grid support connection structure, including a fixed channel steel 3 and a plurality of support beams 1 arranged at intervals along the length direction thereof, the plurality of support beams 1 being arranged at equal intervals along the length direction of the fixed channel steel 3, a screw rod 4 being welded to the top end of the support beam 1, the screw rod 4 being inserted into the fixed channel steel 3, a plurality of groups of mutually symmetrical turbulence tube grid assemblies 2 being erected along the length direction of the fixed channel steel 3, each group of turbulence tube grid assemblies 2 including two mounting slot frames 201 symmetrically mounted in the fixed channel steel 3, a plurality of turbulence tubes 202 being fixedly mounted on the outer side of each mounting slot frame 201, the ends of the plurality of turbulence tubes 202 being fixedly mounted on the mounting slot frame 201 at equal intervals; a clamping plate 6 for clamping the turbulence tube grid assembly 2 is mounted on the screw rod 4, the bottom end of the mounting slot frame 201 close to the screw rod 4 is compressed between the fixed channel steel 3 and the clamping plate 6, a fastening nut 7 is mounted on the screw rod 4 at the top end of the clamping plate 6 for fastening the clamping plate 6. In order not to affect the pressing plate 6 pressing the installation slot frame 201 , in this embodiment, the thickness of the limiting plate 8 is the same as the thickness of the installation slot frame 201 .

[0027] In order to stabilize the two mutually symmetrical groups of turbulent tube grid assemblies 2, a connecting plate is welded to the side of the two symmetrically installed mounting slot frames 201 away from the support beam 1, and the connecting plate is welded to the two mounting slot frames 201 respectively.

[0028] A limit plate 8 is provided between each two adjacent groups of turbulence tube grid assemblies 2 in the fixed channel steel 3. The limit plate 8 is passed through the screw rod 4. The limit plate 8 can be a cross-shaped or T-shaped structure, which is selected according to the setting position of the turbulence tube grid assembly 2. At the same time, the opening size of the limit plate 8 and the screw rod 4 should take into account the offset distance of the limit plate 8 to protect the screw rod 4 from being directly impacted by the turbulence tube grid assembly 2.

[0029] The mounting slot frame 201 of the turbulent tube grid assembly 2 close to one end of the absorption tower wall is clamped on the screw rod 4 through two clamping plates 6, and a supporting rib plate 9 for supporting the screw rod 4 is fixedly installed on the absorption tower wall.

At the same time, the frequently vibrating turbulent grid assembly 2 is damped by the fixed channel steel 3, thereby reducing the impact strength of the anti-corrosion layer on the support beam 1.

[0031] In the present embodiment, the fixed channel steel 3 limits the lateral movement of the turbulence tube grid assembly 2 by means of slotting, and by providing a limit plate 8 between every two adjacent groups of turbulence tube grid assemblies 2 in the fixed channel steel 3, mutual constraints are formed between the multiple groups of turbulence tube grid assemblies 2. Even if one clamping plate 6 is loose, the other turbulence tube grid assemblies 2 will not be affected due to the provision of the fixed channel steel 3 and the limit plate 8.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
