Description

Technical Field

[0001] This utility model relates to the field of hydrogen sulfide gas purification and treatment technology, specifically to a hydrogen sulfide gas purification and treatment device. Background Technology

[0002] Hydrogen sulfide is a colorless, highly toxic acidic gas, the simplest of the sulfur hydrides, and an inorganic compound. At high concentrations, it has no noticeable odor; at low concentrations, it has a strong rotten egg smell; and at extremely low concentrations, it has a sulfurous odor. It is a byproduct of many industrial processes. In industrial applications, hydrogen sulfide is used in the flotation process of sulfide ores and is also an important raw material for the production of sulfur and sulfuric acid. Hydrogen sulfide is mainly used in the synthesis of phosphors, the manufacture of electroluminescence, photoconductors, and photoelectric exposure meters, as a reducing agent in organic synthesis, and in metal refining, pesticides, pharmaceuticals, catalyst regeneration, general reagents, and the preparation of various sulfides. It is also used in the manufacture of inorganic sulfides and in chemical analysis, such as the identification of metal ions.

[0003] Hydrogen sulfide gas purification typically employs spray towers, where atomized alkaline solutions are sprayed through a water distributor. The hydrogen sulfide gas dissolves in the alkaline solution, achieving purification. However, existing spray towers typically have fixed water distributors, resulting in uneven water mist dispersion at points away from and near the nozzle. If the exhaust gas containing hydrogen sulfide flows at a high velocity, the hydrogen sulfide gas may not fully react with the alkaline solution water mist. Furthermore, existing spray towers lack monitoring capabilities, potentially leading to hydrogen sulfide concentrations in the discharged exhaust gas that do not meet emission standards. Therefore, we propose a hydrogen sulfide gas purification and treatment device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hydrogen sulfide gas purification and treatment device. The device uses a swinging water distribution component to make the water mist come into more thorough contact with the hydrogen sulfide gas, and the detection mechanism ensures that the hydrogen sulfide gas is below the emission standard before it can be discharged. This can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen sulfide gas purification and treatment device, comprising a purification cylinder and an atomizing mechanism;

[0006] Purification cylinder: A circulating water pump is installed at the lower right end of the cylinder. The inlet of the circulating water pump is connected to the lower end of the purification cylinder. A water supply pipe is fixedly connected to the upper end of the outlet of the circulating water pump. Two water inlet pipes are installed at the upper end of the water supply pipe. The water inlet pipes are all located inside the purification cylinder. A detection mechanism is installed on the front side of the outer arc of the purification cylinder.

[0007] The atomizing mechanism includes a water distribution assembly, sliding columns, a fixing assembly, and a fixing frame. The purification cylinder has two vertically distributed fixing assemblies inside, each containing a water distribution assembly. These water distribution assemblies are respectively configured to cooperate with vertically adjacent water inlet pipes. Two symmetrically distributed sliding columns are slidably connected between the right sides of the two fixing assemblies. A fixing frame is fixedly connected between the middle of the sliding columns. The oscillating water distribution assembly ensures more thorough contact between the water mist and hydrogen sulfide gas. Simultaneously, a detection mechanism ensures that hydrogen sulfide gas is only emitted when its concentration falls below a certain level.

[0008] Furthermore, it also includes a controller, which is located on the right side of the purification cylinder. The input terminal of the controller is electrically connected to an external power source, and the input terminal of the circulating water pump is electrically connected to the output terminal of the controller, controlling electrical appliances.

[0009] Furthermore, the fixing component includes a mounting bracket, a cross frame, an outer ring, and a sliding seat. Two mounting brackets distributed vertically are fixedly connected to the middle of the inner arc surface of the purification cylinder. The lower end of each mounting bracket is rotatably connected to a cross frame via a pin. The lower end of each cross frame is fixedly connected to an outer ring. Sliding seats are fixedly connected to the upper surfaces of the two supports on the right side of the cross frame. The sliding column is slidably connected between two vertically adjacent sliding seats to realize the swing of the inner ring.

[0010] Furthermore, the water distribution assembly includes water pipes, an inner ring, and a transition pipe. The inner ring is fixedly connected to the inside of the outer ring. The inner ring is provided with evenly distributed water pipes. The lower end of the outer arc surface of the water pipes is fixedly connected with evenly distributed nozzles. The water pipes located in the same inner ring are connected through the transition pipe. The transition pipe is connected to the vertically adjacent water inlet pipe through a connecting hose to realize the spraying of water mist.

[0011] Furthermore, the atomizing mechanism also includes a motor, a turntable, and a lever. The motor is fixedly connected to the outer arc surface of the purification cylinder, the turntable is fixedly connected to the left end of the motor's output shaft, and a lever is fixedly connected to the left side edge of the turntable. The lever is slidably connected to the through hole in the middle of the fixed frame. The input end of the motor is electrically connected to the output end of the controller, driving the outer ring to rotate and swing.

[0012] Furthermore, a swirl plate is fixedly connected to the upper part of the purification cylinder to remove water vapor.

[0013] Furthermore, the detection mechanism includes a first connecting pipe, a second connecting pipe, a circulation pipe, a first valve, a detector, a detection box, and a second valve. The lower end of the purification cylinder is provided with the first connecting pipe, and the upper end of the purification cylinder is provided with the second connecting pipe. The second connecting pipe is located above the swirl plate. The front end of the second connecting pipe is fixedly connected to the detection box, and the upper end of the detection box is fixedly connected to the detector.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This hydrogen sulfide gas purification and treatment device has the following advantages:

[0015] 1. The motor rotates, causing the water pipe to swing at a small angle, making the alkaline solution water mist coverage more even and allowing the hydrogen sulfide in the exhaust gas to come into more thorough contact with the alkaline solution water mist.

[0016] 2. Before the exhaust gas exits the purification cylinder, the concentration of residual hydrogen sulfide gas is detected by a detector. If it meets the emission standards, valve two opens and valve one closes to discharge the gas. If it does not meet the emission standards, valve two closes and valve one opens to continue purifying the gas, ensuring that the discharged exhaust gas meets the emission standards.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-3 This embodiment provides a technical solution: a hydrogen sulfide gas purification and treatment device, including a purification cylinder 1 and an atomizing mechanism 2;

[0023] Purification cylinder 1: A circulating water pump 4 is installed at the lower right end of the cylinder. The inlet of the circulating water pump 4 is connected to the lower end of the purification cylinder 1. A water supply pipe 5 is fixedly connected to the upper end of the outlet of the circulating water pump 4. Two water inlet pipes are provided at the upper end of the water supply pipe 5. Both water inlet pipes are located inside the purification cylinder 1. A detection mechanism 3 is installed on the front side of the outer arc of the purification cylinder 1. A swirl plate 8 is fixedly connected to the upper end of the interior of the purification cylinder 1. The testing mechanism 3 includes a first connecting pipe 31, a second connecting pipe 32, a circulation pipe 33, a first valve 34, a detector 35, a testing box 36, and a second valve 37. The lower end of the purification cylinder 1 is provided with the first connecting pipe 31, and the upper end of the purification cylinder 1 is provided with the second connecting pipe 32. The second connecting pipe 32 is located above the swirl plate 8. The front end of the second connecting pipe 32 is fixedly connected to the testing box 36. The upper end of the testing box 36 is fixedly connected to the detector 35, and the probe of the detector 35 is located inside the testing box 36. The outlet of the testing box 36 is equipped with a second valve 37. The testing box 36 is connected to the first connecting pipe 31 through the circulation pipe 33. The upper end of the circulation pipe 33 is equipped with... A valve 34 is installed, and the detector 35 is electrically connected to the controller 7 in both directions. The input terminals of valve 34 and valve 37 are both electrically connected to the output terminal of the controller 7. Gas with most of the water vapor removed enters the detection chamber 36. The detector 35 detects the concentration of residual hydrogen sulfide gas. If it meets the emission standards, valve 37 opens and valve 34 closes, and the gas is discharged. If it does not meet the emission standards, valve 37 closes and valve 34 opens, and the gas continues to mix with water mist to purify the hydrogen sulfide gas. When the treated gas passes through the swirl plate 8, it drives the swirl plate 8 to rotate. The rotation of the swirl plate 8 drives the gas to rise in a swirling direction, so that the water mist mixed with the gas is thrown to the inner wall of the purification cylinder 1.

[0024] Atomizing mechanism 2 includes a water distribution assembly 21, sliding columns 22, fixing components 23, and fixing frames 24. The purification cylinder 1 has two vertically distributed fixing components 23 inside, each containing a water distribution assembly 21. The water distribution components 21 are respectively configured to cooperate with vertically adjacent water inlet pipes. Two symmetrically distributed sliding columns 22 are slidably connected between the right sides of the two fixing components 23. A fixing frame 24 is fixedly connected between the middle of the sliding columns 22. The fixing components 23 include a mounting bracket 231, a cross frame 232, an outer ring 233, and a sliding seat 234. Two vertically distributed mounting brackets 231 are fixedly connected to the middle of the inner arc surface of the purification cylinder 1. The lower ends of each component are rotatably connected to a cross frame 232 via pins. The lower ends of each cross frame 232 are fixedly connected to an outer ring 233. Sliding seats 234 are fixedly connected to the upper surfaces of the two supports on the right side of the cross frame 232. Sliding columns 22 are slidably connected between two vertically adjacent sliding seats 234. The water distribution assembly 21 includes water pipes 211, an inner ring 212, and a transition pipe 213. The inner ring 212 is fixedly connected inside the outer ring 233. Water pipes 211 are evenly distributed inside the inner ring 212. Evenly distributed nozzles are fixedly connected to the lower ends of the outer arc surfaces of each water pipe 211. Water pipes 211 located within the same inner ring 212 are connected via the transition pipe 213. The vertical pipe 213 is connected to the adjacent vertical water inlet pipe via a connecting hose 6. The atomizing mechanism 2 also includes a motor 25, a turntable 26, and a lever 27. The motor 25 is fixedly connected to the outer arc surface of the purification cylinder 1. The turntable 26 is fixedly connected to the left end of the output shaft of the motor 25. The lever 27 is fixedly connected to the left edge of the turntable 26. The lever 27 is slidably connected to the through hole in the middle of the fixing frame 24. The input end of the motor 25 is electrically connected to the output end of the controller 7. The controller 7 controls the circulating water pump 4 to start. The circulating water pump 4 delivers the alkaline solution into each water pipe 211 through the water supply pipe 5 and the connecting hose 6. The alkaline solution is sprayed out from each nozzle. The output shaft of the motor 25 rotates, driving the turntable 26 to rotate. The disc 26 and lever 27 rotate, and lever 27 drives the fixed frame 24 to rotate. The sliding column 22 slides between two vertically adjacent sliding seats 234, causing the outer ring 233 and inner ring 212 to rotate at a small angle. The sliding seat 234 rotates synchronously with the outer ring 233. At this time, the movement trajectory of the sliding seat 234 is arc-shaped, causing the whole composed of sliding column 22 and fixed frame 24 to move along the same arc-shaped movement trajectory. While the fixed frame 24 swings in an arc, lever 27 slides inside the through hole of the fixed frame 24 and will not disengage from the through hole of the fixed frame 24. The water pipe 211 swings synchronously at a small angle, making the sprayed water mist coverage more uniform and the water mist more fully contacted with hydrogen sulfide gas.

[0025] It also includes a controller 7, which is located on the right side of the purification cylinder 1. The input end of the controller 7 is electrically connected to an external power source, and the input end of the circulating water pump 4 is electrically connected to the output end of the controller 7.

[0026] The working principle of the hydrogen sulfide gas purification device provided by this utility model is as follows: An alkaline solution is injected into the purification cylinder 1, with the height of the alkaline solution lower than the air inlet of the purification cylinder 1. The waste gas to be treated is introduced into the purification cylinder 1. The controller 7 controls the circulating water pump 4 to start. The circulating water pump 4 delivers the alkaline solution into each water pipe 211 through the water supply pipe 5 and the connecting hose 6. The alkaline solution is sprayed out from each nozzle. The output shaft of the motor 25 rotates, driving the turntable 26 and the lever 27 to rotate. The lever 27 drives the fixed frame 24 to rotate. The sliding column 22 slides between two vertically adjacent sliding seats 234, causing the outer ring 233 and the inner ring 212 to rotate at a small angle. The sliding seat 234 rotates synchronously with the outer ring 233. At this time, the movement trajectory of the sliding seat 234 is arc-shaped, driving the entire assembly of the sliding column 22 and the fixed frame 24. The body moves along the same arc-shaped trajectory. While the fixed frame 24 swings in an arc, the lever 27 slides inside the through hole of the fixed frame 24 and will not disengage from the through hole of the fixed frame 24. The water pipe 211 swings at a small angle simultaneously, making the sprayed water mist coverage more uniform and the water mist more fully in contact with the hydrogen sulfide gas. When the treated gas passes through the swirl plate 8, it drives the swirl plate 8 to rotate. The rotation of the swirl plate 8 drives the gas to rise in a swirling direction, so that the water mist mixed with the gas is thrown to the inner wall of the purification cylinder 1. The gas with most of the water vapor removed enters the detection box 36. The detector 35 detects the concentration of residual hydrogen sulfide gas. If it meets the emission standards, valve 2 37 opens and valve 1 34 closes, and the gas is discharged. If it does not meet the emission standards, valve 2 37 closes and valve 1 34 opens, and the gas continues to mix with the water mist, purifying the hydrogen sulfide gas.

[0027] It is worth noting that the controller 7 disclosed in the above embodiments can be an STM32F103RCT6, the circulating water pump 4 can be a DBY3-40STFF electric diaphragm pump, the motor 25 can be a BLD series geared motor, the detector 35 can be an EA900-O2 gas detector, and both valve one 34 and valve two 37 can be D971X-16 electric flange butterfly valves. The controller 7 controls the operation of the circulating water pump 4, motor 25, detector 35, valve one 34 and valve two 37 using methods commonly used in the prior art.
