Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of alkaline spraying equipment, specifically to an alkaline spraying equipment for sodium cyanide production. Background Technology
[0002] The alkaline solution absorption spray system in sodium cyanide production equipment is a key piece of equipment for treating hydrogen cyanide gas. Its main function is to absorb and neutralize hydrogen cyanide through alkaline solution spraying, ensuring safety and environmental friendliness in the production process. The spray tower is the core component of the equipment, typically made of corrosion-resistant materials to ensure long-term stable operation in a strongly alkaline environment. The tower has multiple spray layers, each equipped with nozzles, to evenly spray the alkaline solution. The alkaline solution is usually a sodium hydroxide solution, which effectively neutralizes hydrogen cyanide to produce a non-toxic sodium cyanide solution. Traditional alkaline solution absorption nozzles have a relatively simple structure, making it difficult to form fine droplets and resulting in a small gas-liquid contact area, thus leading to absorption efficiency that cannot meet production requirements.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-5This utility model provides a sodium cyanide production equipment for absorbing alkaline solution spraying, including a main pipe 1, with auxiliary pipes 2 on both sides of the side wall of the main pipe 1, and four auxiliary pipes 2 in total. Each of the four auxiliary pipes 2 has a spray end head 3 at its outer end. The upper end of the spray end head 3 has a connecting end head 4. An adjusting rod 5 is threadedly connected through the middle position of the connecting end head 4. The lower end of the adjusting rod 5 has an adjusting end head 6. The adjusting end head 6 extends into the lower end of the spray end head 3. An adjusting seat 7 is provided at the lower end of the spray end head 3 corresponding to the adjusting end head 6. The lower end of the adjusting seat 7 has a spray nozzle 8.
[0018] In use, the entire spraying equipment is installed inside the spraying tower. The external alkaline solution is input through the main pipe 1 and then distributed to the interiors of four spray heads 3 through the secondary pipe 2. A connecting end 4 is threaded onto the upper end of the spray head 3, and an adjusting rod 5 is threaded onto the interior of the connecting end 4. An adjusting end 6 is installed at the lower end of the adjusting rod 5. An adjusting seat 7 is installed at the lower end of the spray head 3 corresponding to the adjusting end 6. A nozzle 8 is installed on the adjusting seat 7. The alkaline solution is sprayed outward through the nozzle 8. By turning the adjusting rod 5, the adjusting rod 5 moves up and down relative to the connecting end 4, thereby moving the adjusting end 6 closer to or away from the adjusting seat 7, thus adjusting the gap between the adjusting end 6 and the adjusting seat 7, so that the alkaline solution is sprayed outward through the gap. Combined with the nozzle 8, the uniformity of the alkaline solution spraying is improved.
[0019] The upper and lower ends of the adjusting rod 5 are a threaded section and a sliding section, respectively. The threaded section of the adjusting rod 5 is connected to a fixing nut 9 by a thread. The lower end of the fixing nut 9 abuts against the upper end of the connecting end 4. The lower inner end of the connecting end 4 is connected to a sealing end 10 by a thread. The sliding section of the adjusting rod 5 is slidably connected to the sealing end 10. The threaded section of the adjusting rod 5 is threadedly connected to the connecting end 4, and the fixing nut 9 is threadedly connected to the threaded section to improve the connection between the adjusting rod 5 and the connecting end 4. The sealing end 10 is provided at the lower end of the connecting end 4 to ensure the sealing between the connecting end 4 and the adjusting rod 5.

The main pipe 1 is located on one side of the center of the circle, and the four auxiliary pipes 2 are all arranged perpendicular to the main pipe 1. By setting the four spray heads 3 at the four directions of the same circle, the uniformity of spraying of the entire spraying equipment is ensured. The main pipe 1 avoids the center of the circle and is connected to the spray heads 3 through the auxiliary pipes 2.
[0021] The nozzle 8 is connected to the inner cavity of the spray end 3. The adjusting end 6 rests against the nozzle 8. The absorbed alkaline solution is sprayed out through the gap between the nozzle 8, the adjusting end 6 and the adjusting seat 7 to ensure uniform spraying.
