Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection of a desulfurization tower, in particular to a pipeline connection structure for a desulfurization tower. Background Art

[0002] Desulfurization towers were initially built with granite, and were the most widely used. They utilize the principle of water film desulfurization and dust removal, and are also known as granite water film desulfurization dust collectors or granite water film desulfurization dust collectors. Their advantages include ease of maintenance and the ability to simultaneously achieve both dust removal and desulfurization (denitrification) by combining various dust removal agents.

[0003] The existing desulfurization tower will have DN200 seamless pipes laid on the surface, parallel to the PSA hydrogen production steam main, with blind plugs installed at both ends of the pipe and a drain guide installed at the bottom to facilitate pipeline purging and inspection. The inlet and outlet welded pipelines of each desulfurization tower are connected to the main pipe, and butterfly valves are installed at appropriate locations on each branch pipe for series switching of the towers. This increases desulfurizer regeneration and series operation, increases the system's service life under high-sulfur operating conditions, improves desulfurizer utilization efficiency, and reduces production costs. The frequency of desulfurization agent replacement is reduced, reducing safety risks during production operations and reducing the generation of solid waste. At the same time, by setting the three desulfurization towers to switchable modes in series and parallel, and using 1 in use and 2 in standby or 2 in use and 1 in standby, online removal and replacement of desulfurizers can be achieved without affecting production.

[0004] However, during the actual installation process, the flanges of the pipe and butterfly valve need to be precisely aligned to ensure that the mounting holes between the flanges correspond one to one before bolting. This step places high demands on the installer's operating accuracy and physical strength. The installer needs to continuously support the butterfly valve to prevent it from shifting during installation. However, in actual operation, due to reasons such as exhaustion or accidental contact, the butterfly valve often shifts, resulting in flange alignment failure and the need for reinstallation. This not only seriously affects installation efficiency but also increases installation costs and time. Utility Model Content

The stabilizing component 8 also includes a limiting member 85, and the plug rod 81 is inserted into the socket 84 to stabilize the fixing plate 1 80 and the fixing plate 2 83.

[0024] The limiting member 85 includes a rotating plate 850, which is rotatably connected to the surface of the flange 10. The surface of the rotating plate 850 is provided with a contact hole 851. The inner wall of the contact hole 851 contacts a short rod 852. A clamping block 853 is fixed to the surface of the short rod 852. A stabilizing plate 854 is fixed to the surface of the fixing plate 83. A fixing frame 856 is fixed to the surface of the stabilizing plate 854. The clamping block 853 is slidably connected to the inner side of the fixing frame 856. A spring 855 is fixed to the surface of the clamping block 853. The end of the spring 855 away from the clamping block 853 is fixed to the stabilizing plate 8 54, a fixing rod 857 is fixed on the surface of the rotating plate 850, and a pull plate 858 is fixed on the end of the fixing rod 857 away from the rotating plate 850.
