Description

Technical Field

[0001] This utility model belongs to the technical field of desulfurization spray system pipelines, and in particular relates to a desulfurization spray device. Background Technology

[0002] A desulfurization tower is a device used to treat industrial waste gas. It is mainly used to remove harmful substances such as sulfur dioxide from the waste gas. It uses a spray system to react water or other absorbents with the sulfur dioxide in the waste gas, thereby converting it into harmless substances.

[0003] In traditional desulfurization tower spray systems, the main pipeline is usually arranged in a grid-like structure, located in the core area inside the tower. From this central main pipeline, multiple branch pipelines extend out to achieve comprehensive spraying of the inside of the desulfurization tower. However, as the desulfurization tower operates for a long time, limestone crystallizes and deposits on the inner wall of the pipeline, gradually leading to pipeline blockage. Once the pipeline is blocked, workers need to enter the desulfurization tower to replace and clean these blocked pipelines. This work is not only cumbersome, but also poses a high safety risk to workers due to the complex environment and space constraints inside the tower. Utility Model Content

[0009] Furthermore, the inner walls of several of the second flanges are fitted to the outer walls of the short spray pipes, and the inner walls of the remaining several second flanges are fitted to the inner walls of the long spray pipes.

[0010] As a further description of the above technical solution:

[0011] One end of the long spray pipe extends into the desulfurization tower, and the other end of the short spray pipe extends into the desulfurization tower.

[0012] As a further description of the above technical solution:

[0025] 1. In this utility model, by setting up a first flange assembly, a second flange assembly, a first flange plate, a second flange plate, a threaded groove, and flange bolts, the coil can be disassembled by rotating the bolts on the first flange assembly and the second flange assembly. The short spray pipe and the long spray pipe can be disassembled by rotating the flange bolts, so that they can be taken out from the desulfurization tower body and the second flange plate. This makes it easier for workers to replace and clean the blocked pipes, making pipe replacement and cleaning easier and eliminating the need for workers to enter the tower to replace and clean the pipes, thereby improving the safety of workers.

This increases the spraying range of the nozzles, making the spray more uniform and improving the spraying effect. It also ensures that the lime water sprayed from the nozzles can fully and completely contact the sulfur gas, thereby improving the desulfurization efficiency and effect. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0034] A desulfurization spray device, such as Figures 1-5As shown, the system includes a desulfurization tower body 1, with multiple coils 2 installed outside the tower body 1. Adjacent coils 2 are connected and interconnected via a first flange assembly 4. A first flexible hose 12 and a second flexible hose 18 are respectively connected to the outer wall of each coil 2. A long spray pipe 10 is connected to the other end of the first flexible hose 12, and a short spray pipe 7 is connected to the other end of the second flexible hose 18. Multiple through grooves 15 are formed on the outer wall of the desulfurization tower body 1. A second flange 6 is connected to the inner wall of each through groove 15, and a first flange is attached to one side of the second flange 6. The first flange 5 has multiple through holes, and flange bolts 13 are fitted inside the through holes. The second flange 6 has multiple threaded grooves 11, one side of which is connected to the side of the through hole. The inner walls of multiple first flanges 5 are connected to the outer walls of short spray pipes 7, and the inner walls of the remaining multiple first flanges 5 are connected to the outer walls of long spray pipes 10. The inner walls of multiple second flanges 6 are fitted to the outer walls of short spray pipes 7, and the inner walls of the remaining multiple second flanges 6 are fitted to the inner walls of long spray pipes 10.

[0035] The specific implementation method is as follows: By rotating the screws provided on the first flange assembly 4 and the second flange assembly 17, the first flange assembly 4 and the second flange assembly 17 can be disassembled, thereby allowing the multiple coils 2 to be disassembled. By providing the first flange 5, the second flange 6, the threaded groove 11, and the flange screws 13, rotating the flange screws 13 separates the flange screws 13 from the threaded groove 11, thereby allowing the first flange 5 and the second flange 6 to be disassembled. This allows the short spray pipes 7 and the long spray pipes 10 to be removed from the desulfurization tower body 1 and the second flange 6, making it easier for workers to replace and clean the blocked pipes. This makes pipe replacement and cleaning easier and eliminates the need for workers to enter the tower to replace and clean the pipes, thus improving the safety of workers. Example 2

[0036] One end of the long spray pipe 10 extends into the desulfurization tower body 1, and one end of the short spray pipe 7 extends into the desulfurization tower body 1. One end of the short spray pipe 7 is connected to the first nozzle 8, and one end of the long spray pipe 10 is connected to the second nozzle 9. One end of the flange bolt 13 extends into the threaded groove 11. The outer wall of the flange bolt 13 is threadedly connected to the inner wall of the threaded groove 11. One side of the head of the flange bolt 13 is attached to one side of the first flange 5. Multiple coils 2 are spirally wound around the outside of the desulfurization tower body 1, and one end of one coil 2 is connected to the second flange assembly 17. The other side of the second flange assembly 17 is connected to the water inlet pipe 3.

[0037] The specific implementation method is as follows: Due to the spiral winding arrangement of the coil 2, the long spray pipe 10 and the short spray pipe 7 can surround the desulfurization tower body 1 and be evenly distributed outside the tower body, thereby increasing the spraying range of the nozzles and making the spraying more uniform, thus improving the spraying effect of the nozzles. This allows the lime water sprayed from the nozzles to fully and completely contact the sulfur gas, thereby improving the desulfurization efficiency and effect. The different lengths of the long spray pipe 10 and the short spray pipe 7 allow the nozzles to spray at different distances, thereby increasing the spraying range of the nozzles and improving the spraying effect of the nozzles. Example 3

[0038] Multiple support frames 14 are connected to the outer wall of the desulfurization tower body 1. A groove 16 is provided on one side of the support frame 14. The inner wall of the groove 16 is arc-shaped and fits against the outer wall of the corresponding coil 2.

[0039] The specific implementation method is as follows: the support frame 14 can support the coil 2, thereby improving the overall stability of the coil 2. By setting the groove 16, since the inner wall of the groove 16 is set as an arc surface, it can better fit with the outer surface of the coil 2, thereby increasing the contact area between the outer surface of the coil 2 and the support frame 14, increasing the friction between the outer surface of the coil 2 and the support frame 14, thereby preventing the coil 2 from sliding between the support frame 14 and improving the stability of the support frame 14.

[0040] Working principle: During use, by rotating the screws on the first flange assembly 4 and the second flange assembly 17, the first flange assembly 4 and the second flange assembly 17 can be disassembled, allowing multiple coils 2 to be removed. By rotating the flange screw 13, the flange screw 13 is separated from the threaded groove 11, thereby allowing the first flange 5 and the second flange 6 to be disassembled. This allows the short spray pipe 7 and the long spray pipe 10 to be removed from inside the desulfurization tower body 1 and the second flange 6, making it convenient for staff to replace and clean blocked pipes. Since the coils 2 are arranged in a spiral winding manner, the long spray pipe 10 and the short spray pipe 7 can be wrapped around the desulfurization tower body 1 and evenly distributed outside the tower body, thereby increasing the spray range of the nozzles and making the spray more uniform.
