Description
Technical Field
[0001] The utility model relates to the technical field of chemical production, in particular to a tubular acid distributor for concentrated sulfuric acid production. Background Technique
[0002] In the flue gas drying (absorption) process of the sulfuric acid production system from smelting flue gas, the drying (absorption) tower is one of the core equipment, and the acid distributor is an important part of the drying (absorption) tower. It directly affects the effective wetting area of the packing and the gas-liquid mass transfer efficiency. Uniform acid distribution is an important prerequisite to ensure that the drying (absorption) tower achieves the expected drying and absorption efficiency.
[0003] The internal structure of the existing tubular acid distributor is relatively simple. When assembling multiple tubular acid distributors, most of them are fixedly connected by screwing multiple groups of threads. Although this fixing method is relatively firm, it is not convenient for operators to perform quick disassembly and maintenance work later, reducing the inconvenience and complexity of the assembly and fixing of the tubular acid distributor. Moreover, most of the nozzles designed inside the tubular acid distributor are fixedly connected. This connection method is not convenient for operators to disassemble and replace a single nozzle later. When the nozzle is corroded and the through-hole is too large, it will cause leakage inside the tubular acid distributor, affecting the later use effect. Content of the Utility Model
[0004] The purpose of the utility model is to provide a tubular acid distributor for concentrated sulfuric acid production, which is convenient for operators to assemble multiple tubular acid distributors without the need for operators to perform multiple groups of thread screwing operations, so as to improve the convenience and practicality of its assembly and use. At the same time, it can also realize the disassembly and assembly function of the nozzle and the acid distributor, facilitating the replacement operation of a single nozzle by operators later, and reducing the leakage phenomenon caused by the corrosion of the nozzle and the excessive through-hole.

At the same time, the disassembly and assembly function of the nozzle and the acid distributor can be realized, which is convenient for operators to replace a single nozzle later, and reduces the leakage phenomenon caused by the over-sized through hole due to the corrosion of the nozzle.

[0026] The disassembly and assembly component includes a through port 3, an internal thread sleeve 6, a nozzle 7, a thread 8, an extension pipe 9, and a sealing ring 10. There are multiple groups of through ports 3, and the multiple groups of through ports 3 are evenly arranged at the bottom of multiple acid distribution branch pipes 4. At the bottom outside the multiple groups of through ports 3, there is an internal thread sleeve 6 connected to the acid distribution branch pipe 4, and the internal thread sleeve 6 is communicated with the inside of the through port 3. The inside of the internal thread sleeve 6 and the through port 3 are both inserted with a nozzle 7 that matches them. At the bottom outside the nozzle 7, there is a thread 8 that meshes with the internal thread sleeve 6. At the top outside the nozzle 7, there is a sealing ring 10 that matches the through port 3. At the middle position of the top of the nozzle 7, there is an extension pipe 9 that extends into the inside of the through port 3.
[0027] The fixing component includes a spring 14, a fixing rod 15, and a fixing groove 16. There are multiple groups of fixing grooves 16, and the multiple groups of fixing grooves 16 are evenly arranged inside the annular sliding groove 18. There are two groups of fixing rods 15, and the two groups of fixing rods 15 penetrate through the inside of the slider 17 and the connecting rod 12, and the fixing rods 15 extend into the inside of the fixing groove 16 and match with it. At the middle position outside the two groups of fixing rods 15, there is a spring 14 connected to the slider 17.
[0028] Through holes that match the fixing rods 15 are provided inside the two groups of sliders 17 and the connecting rods 12, and limit sliders are provided at the top and bottom inside the two groups of through holes.

[0032] When it is necessary to disassemble and replace the nozzle 7 later, the operator can directly rotate the nozzle 7 to drive the thread 8 to rotate and remove it inside the internal thread sleeve 6. Then, the nozzle 7 can drive the extension pipe 9 and the sealing ring 10 to be removed into the through port 3, which is convenient for the operator to replace the nozzle 7 and the components above it, reducing the leakage phenomenon caused by the corrosion of the through port. Later, by rotating the thread 8 of the nozzle 7 in the reverse direction, the nozzle 7 can drive the extension pipe 9 to be inserted into the through port 3. Finally, through the sealing ring 10, the fixing and sealing operation of the nozzle 7 and the components above it can be completed.
