Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization, in particular to a spray device for a desulfurization tower. Background Art

[0002] At present, wet flue gas desulfurization towers are widely used in the purification process of industrial high-sulfur tail gas. Among them, the lime-gypsum wet flue gas desulfurization process is the most commonly used. The lime slurry is atomized by a high-pressure nozzle and then contacts the high-sulfur tail gas in countercurrent. The pollutants contained in the tail gas are removed through a strong mass transfer effect, which has a good effect. The current spray device is installed inside the desulfurization tower, and there are only one or two supporting beams inside. During maintenance, it is both high-altitude operation and confined space operation, which has a high risk factor. At the same time, the maintenance time is also long, which affects the production time and operation efficiency of the entire system.

[0003] Authorized patent CN 216223780 U discloses a ring pipe spray device for desulfurization tower spraying, including a desulfurization tower wall and a sealing flange seat, wherein a disassembly-borrowing hollow rib is fixedly installed between the outer surface of the sealing flange seat and the desulfurization tower wall, and a sealing spray pipe structure is arranged on one side surface of the sealing flange seat. The ring pipe main pipeline is installed outside the desulfurization tower, and the upper branch pipelines are evenly arranged in sections on the ring pipe main pipeline. Then, the spray pipe and the internal spray nozzle are used to probe into the desulfurization tower. When a single spray pipe is blocked or damaged, the flange can be unfastened outside the desulfurization tower to replace the single spray pipe, which effectively solves the problem that the desulfurization effect is affected by spraying problems and the internal spray nozzle needs to be stopped when replacing, as well as safety hazards.

[0004] However, the above device still needs to use dislocated hollow ribs when dismantling the spray pipes. Both dismantling and installing the pipes require certain skills. In addition, since the maintenance does not stop the machine, when the spray pipes are dismantled, the interior of the desulfurization tower is connected to the atmosphere, and the untreated gas in the tower body and the desulfurization slurry in other spray pipes will seep out of the tower, causing harm to the environment and the health of the workers. Utility Model Content

[0005] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a spray device for a desulfurization tower.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a spray device for a desulfurization tower, comprising an annular tube, which is arranged around the outside of the desulfurization tower body, and a plurality of branch pipes are evenly arranged on the annular tube, and the branch pipes are connected to the spray pipes, and the spray pipes are arranged along the radial direction of the desulfurization tower body, and the spray pipes are connected to the desulfurization tower body through a sealing flange seat, and the sealing flange seat is fixed to the outer wall of the desulfurization tower body. A bracket is arranged in the sealing flange seat, and support rods are fixedly connected to the bracket, and the support rods are arranged in pairs and contact with the spray pipes. A limit block is provided at one end of the support rod away from the bracket, and baffles are slidably arranged on the two support rods, and the baffles match the through holes on the outer wall of the desulfurization tower body. A magnet is embedded in the end of the spray pipe.

[0007] Furthermore, a limiting ring is provided at the through hole, and the limiting ring is fixedly connected to the outer wall of the desulfurization tower body by bolts, and a magnetic ring is provided on the limiting ring near the through hole.

[0008] Furthermore, a plurality of nozzles are provided at the bottom of the spray pipe, and the spray pipe enters the interior of the desulfurization tower body through a limiting ring and a through hole.

[0009] Furthermore, a flange matching plate is fixedly arranged on the spray pipe, and the spray pipe is connected to the sealing flange seat via the flange matching plate.

[0010] Furthermore, the bracket is fixedly connected to the side wall of the sealing flange seat, and the support rod is arranged parallel to the spray pipe.

[0011] Furthermore, the outer end of the spray pipe is bent downward and connected to the branch pipeline through a flange set, the flange set is below the horizontal height of the sealing flange seat, and a pipeline valve is provided on the branch pipeline.

[0012] The beneficial effects of the utility model are:

[0013] 1. Tighten the pipeline valve and loosen the flange set, separate the connection between the sealing flange seat and the flange matching plate, and pull out the spray pipe horizontally. The spray pipe is easy and quick to disassemble, which improves work efficiency;

[0024] In this embodiment, if Figure 2 and Figure 3As shown, a limiting ring 12 is provided at the through hole 10, and the limiting ring 12 is fixedly connected to the outer wall of the desulfurization tower body 2 by bolts. A magnetic ring 13 is provided on the limiting ring 12 close to the through hole 10. When the spray pipe 4 moves out of the desulfurization tower body 2, the baffle 9 can move outward therewith, and be adsorbed by the magnetic ring 13 at the through hole 10, so that the through hole 10 is closed to prevent the gas and desulfurization slurry from diffusing from the through hole 10 to the outside of the desulfurization tower body 2.

[0025] In this embodiment, a plurality of nozzles 14 are provided at the bottom of the spray pipe 4. The spray pipe 4 enters the interior of the spray tower body 1 through the limiting ring 12 and the through hole 10. The nozzles 14 pass between the two support rods 7 without affecting the spraying effect.

[0026] In this embodiment, a flange matching plate 15 is fixedly provided on the spray pipe 4 , and the spray pipe 4 is connected to the sealing flange seat 5 via the flange matching plate 15 .
