Description

Technical Field

[0001] This utility model relates to the field of hydrogen sulfide absorption tower technology, and more specifically to a hydrogen sulfide absorption tower. Background Technology

[0002] Hydrogen sulfide is an inorganic compound with the chemical formula HS. Under normal conditions, it is a colorless, flammable acidic gas. Industrial emissions of hydrogen sulfide not only corrode equipment, but also have very strict emission requirements. If not handled carefully, it can seriously pollute the environment. When using NaOH liquid to absorb hydrogen sulfide, a large amount of salt is produced. Salt particles easily deposit on the tower wall and cause blockage of the hydrogen sulfide inlet pipe.

[0003] According to the search, a hydrogen sulfide absorption tower disclosed in publication number CN217725127U includes an absorption tower body, an air outlet at the top of the absorption tower body, a liquid outlet at the bottom of the absorption tower body, a first annular pipe at the bottom of the absorption tower body, the first annular pipe being connected to a hydrogen sulfide supply system through a first air inlet pipe, a plurality of first nozzles being vertically arranged on the first annular pipe, the plurality of first nozzles being arranged upward and evenly distributed along the circumference of the first annular pipe, and a plurality of single-sided holes being opened at the bottom of the first annular pipe.

[0004] The above-described technical solution has certain beneficial effects, but in actual use, when hydrogen sulfide gas flows upward through the inside of the filter hole, NaOH liquid drips onto the surface of the inclined plate and flows into the inside of the filter hole to react, which can easily cause blockage, thus preventing hydrogen sulfide from flowing upward. Therefore, we propose a hydrogen sulfide absorption tower. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figure 1-5 This utility model provides a hydrogen sulfide absorption tower, including an absorption tower 1. A support frame 2 is fixedly sleeved on the lower part of the surface of the absorption tower 1. Fixed legs 3 are symmetrically provided on both front ends of the absorption tower 1. A connecting threaded rod 5 is movably inserted into the inner side of the fixed leg 3. A connecting leg 4 is fixedly connected to one end of the connecting threaded rod 5. A fastening nut 6 is threadedly connected to the outer side of the surface of the connecting threaded rod 5. A connecting absorption and discharge mechanism 7 is fixedly connected to one end of the connecting leg 4.

[0024] The absorption tower 1 has a fixed support plate 8 symmetrically arranged on its inner side, a first positioning groove 9 symmetrically opened on its inner side, and a second positioning groove 10 opened in the middle of its inner side.

[0025] The absorption and discharge mechanism 7 includes a connecting mounting plate 11. A sodium hydroxide nozzle 12 is fixedly connected to one side of the connecting mounting plate 11, and a conveying pipe 13 is fixedly connected to one end of the sodium hydroxide nozzle 12. A gas conveying pipe 14 is symmetrically arranged inside the connecting mounting plate 11, and an outlet 15 is opened on the end surface of the gas conveying pipe 14. A fixed guide plate 16 is symmetrically arranged on one side of the connecting mounting plate 11, and a fixed collection plate 17 is fixedly connected to one side of the connecting mounting plate 11. A fixed mounting frame 18 is fixedly connected to the other side of the connecting mounting plate 11, and an output motor 19 is fixedly connected to the surface of the fixed mounting frame 18. A spiral discharge roller 20 is fixedly connected to the output end of the output motor 19, facilitating the insertion of the fixed guide plate 16 and the fixed collection plate 17 into the inner side of the absorption tower 1, so that the fixed guide plate 16... The flow plate 16 and the fixed collection plate 17 can be inserted into the inner sides of the first positioning groove 9 and the second positioning groove 10 respectively, so that the connecting mounting plate 11 and the absorption tower 1 fit together, and the connecting threaded rod 5 is inserted into the inner side of the fixed support leg 3 and connected and fastened by the fastening nut 6. Then, the gas supply pipe 14 and the gas outlet 15 deliver hydrogen sulfide gas into the absorption tower 1, and guide it through the fixed guide plate 16, so that the hydrogen sulfide moves to the bottom of the sodium hydroxide nozzle 12 and the top of the fixed collection plate 17. Then, the supply pipe 13 delivers sodium hydroxide liquid into the sodium hydroxide nozzle 12, which reacts and neutralizes with the hydrogen sulfide gas, so that the salt particles can stay on the top of the fixed collection plate 17, thereby absorbing the hydrogen sulfide. The operation is convenient.

[0026] The fixed mounting bracket 18 has fixed limiting frames 21 on both sides of its bottom. Fixed limiting blocks 22 are fixedly connected to the top two ends of the surface of the fixed mounting bracket 18. Connecting blocks 24 are movably inserted into the inner side of the fixed limiting frames 21. A connecting sealing block 23 is fixedly connected to one side of the connecting blocks 24. A fixed positioning rod 25 is fixedly connected to one end of the connecting blocks 24. A movable deflection arm 26 is movably sleeved on the outer side of the fixed positioning rod 25. This allows the movable deflection arm 26 to deflect on the outer side of the fixed positioning rod 25 when salt particles need to be discharged, enabling the movable deflection arm 26 to... The first handle 27 can be pulled out from the inside of the fixed limiting block 22, and then the connecting sealing bottom block 23, connecting insert block 24, fixed positioning rod 25 and movable deflection arm 26 can be moved, so that the connecting insert block 24 can be pulled out from the inside of the fixed limiting frame 21, and the connecting sealing bottom block 23 can be disengaged from the bottom of the fixed mounting frame 18. Then the output motor 19 drives the spiral discharge roller 20, so that when the spiral discharge roller 20 rotates, it can discharge the salt particles on the top of the fixed collection plate 17 to the outside and discharge them from the bottom of the fixed mounting frame 18 to the outside, which is convenient to operate.

[0027] The bottom of the connecting sealing block 23 is fixedly connected to a first handle 27, which facilitates the movement of the first handle 27. This movement can drive the connecting sealing block 23, the connecting insert block 24, the fixed positioning rod 25, and the movable deflection arm 26 to move, thereby disassembling the connecting sealing block 23. This operation is convenient.

[0028] The connecting mounting plate 11 is symmetrically provided with a second handle 28 on the other side, which facilitates the movement of the second handle 28 and can quickly drive the entire connecting absorption and discharge mechanism 7 to move, making operation convenient.

[0029] The outer surface of the movable deflection arm 26 slides against the inner surface of the fixed limiting block 22, the outer surface of the connecting plug 24 slides against the inner surface of the fixed limiting frame 21, and the bottom inner surface of the connecting sealing block 23 is against the bottom of the fixed mounting bracket 18. This allows the movable deflection arm 26 to be stably locked inside the fixed limiting block 22, the connecting plug 24 to be stably inserted into the inner surface of the fixed limiting frame 21, and the connecting sealing block 23 to stably seal the bottom of the fixed mounting bracket 18. The operation is convenient and quick.

[0030] The working principle of this utility model is as follows: First, the fixed guide plate 16 and the fixed collection plate 17 are inserted into the inner side of the absorption tower 1, allowing them to fit into the first positioning groove 9 and the second positioning groove 10 respectively. This ensures the connecting mounting plate 11 is in close contact with the absorption tower 1, and the connecting threaded rod 5 is inserted into the inner side of the fixed support leg 3. The connection is then secured with the fastening nut 6. Next, the gas supply pipe 14 and the gas outlet 15 supply hydrogen sulfide gas into the absorption tower 1, guided by the fixed guide plate 16, causing the hydrogen sulfide to move to the bottom of the sodium hydroxide nozzle 12 and the top of the fixed collection plate 17. Then, the supply pipe 13 supplies sodium hydroxide liquid into the sodium hydroxide nozzle 12, where it reacts with the hydrogen sulfide gas to neutralize it. This allows the salt particles to remain on the top of the fixed collection plate 17, thus absorbing the hydrogen sulfide. When a large amount of salt particles are collected at the top of the fixed collection plate 17, the supply of hydrogen sulfide gas to the interior of the absorption tower 1 is stopped. Then, the movable deflection arm 26 is deflected on the outer side of the fixed positioning rod 25, allowing the movable deflection arm 26 to be pulled out from the inner side of the fixed limiting block 22. Then, the first handle 27 is moved, driving the connecting sealing bottom block 23, connecting insert block 24, fixed positioning rod 25, and movable deflection arm 26 to move, allowing the connecting insert block 24 to be pulled out from the inner side of the fixed limiting frame 21, and allowing the connecting sealing bottom block 23 to detach from the bottom of the fixed mounting frame 18. Then, the output motor 19 drives the spiral discharge roller 20, so that when the spiral discharge roller 20 rotates, it can discharge the salt particles at the top of the fixed collection plate 17 to the outside and from the bottom of the fixed mounting frame 18 to the outside, thereby stably absorbing and treating the hydrogen sulfide gas. The overall structure is simple and the operation is convenient and quick.
