Description

Technical Field

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

[0002] Hydrogen sulfide tail gas is fed into an absorption tower and comes into countercurrent contact with the sprayed absorbent. H2S is dissolved and converted, and the purified gas is discharged in compliance with standards. The rich liquid is regenerated or treated and then recycled. Alkaline absorbent (such as NaOH solution) is used to react with H2S in an acid-base neutralization reaction to produce sodium sulfide (Na2S) or sodium hydrosulfide (NaHS), thereby purifying the tail gas.

[0003] In current technologies, hydrogen sulfide tail gas is treated by spraying an absorbent onto the tail gas to absorb the hydrogen sulfide contained in the tail gas and then purifying it. However, the spraying method is relatively simple, resulting in the tail gas not being evenly sprayed by the absorbent, which reduces the treatment effect of hydrogen sulfide tail gas. Therefore, a hydrogen sulfide tail gas treatment device is proposed to address the above problems. Utility Model Content

[0012] This invention provides a hydrogen sulfide tail gas treatment device. The device connects a tail gas emission device to the end of the tail gas inlet pipe to discharge tail gas into the hydrogen sulfide tail gas treatment tank. An absorbent is then introduced into an absorbent inlet pipe, flowing through the absorbent inlet pipe into a sealed box, and then into a rotating pipe. A motor is then turned on, causing the rotating pipe to rotate at the bottom of the sealed box. During rotation, the discharge port of the rotating pipe opens to both sides due to centrifugal force, allowing the absorbent inside the rotating pipe to be sprayed outwards through the discharge port. This evenly and thoroughly absorbs the tail gas inside the hydrogen sulfide tail gas treatment tank, effectively treating the hydrogen sulfide tail gas. A filter screen is then used for secondary purification of the tail gas, further improving the treatment effect of the hydrogen sulfide tail gas.

During operation, when hydrogen sulfide needs to be treated... When treating the exhaust gas, the exhaust gas emission device is connected to the end of the exhaust gas inlet pipe 22 to discharge the exhaust gas into the hydrogen sulfide exhaust gas treatment tank 21. Then, the absorbent is introduced into the absorbent inlet pipe 24, and then flows through the absorbent inlet pipe 24 into the sealed box 25, and then into the rotating pipe 26. Then, the motor 23 is turned on, and the output end of the motor 23 drives the rotating pipe 26 to rotate at the bottom of the sealed box 25. During the rotation of the rotating pipe 26, the discharge hole 27 is rotated and opened to both sides due to the influence of centrifugal force. Then, the absorbent inside the rotating pipe 26 is sprayed to the outside through the discharge hole 27, and then the exhaust gas inside the hydrogen sulfide exhaust gas treatment tank 21 is evenly mixed and absorbed to effectively absorb and treat the hydrogen sulfide exhaust gas. Then, the exhaust gas is further purified by the filter screen 35, which improves the treatment effect of hydrogen sulfide exhaust gas.

[0025] Furthermore, such as Figures 3-4 As shown, a pull rope 29 is fixedly connected to the end of the discharge hole 27; a gravity ball 31 is fixedly connected to the end of the pull rope 29; during operation, when the rotating tube 26 rotates, it drives the pull rope 29 and the gravity ball 31 to rotate. Under the influence of centrifugal force, the gravity ball 31 is pulled towards the end, which drives the sealing plate 28 to rotate towards the end, so that the sealing plate 28 can open quickly, allowing the absorbent to be sprayed and absorbed by the outside through the discharge hole 27.

[0026] Furthermore, such as Figures 3-4 As shown, a guide rod 32 is fixedly connected to the end of the rotating tube 26; a stirring rod 33 is fixedly connected to the end of the guide rod 32; during operation, when the rotating tube 26 rotates, it drives the guide rod 32 and the stirring rod 33 to rotate, thereby stirring and dispersing the absorbent, so that the absorbent can be sprayed more evenly.

[0027] Furthermore, such as Figures 3-4 As shown, a cleaning plate 41 is fixedly connected to the bottom of the rotating tube 26; a cleaning brush 42 is fixedly connected to the bottom of the cleaning plate 41 and is located on top of the filter screen 35; during operation, when the rotating tube 26 rotates, it drives the cleaning plate 41 to rotate, so that the cleaning plate 41 drives the cleaning brush 42 to adhere to the surface of the filter screen 35 for cleaning, thereby reducing the problem of impurities accumulating and clogging the filter screen 35 during the filtration process.

[0028] Furthermore, such as Figures 3-4 As shown, a plurality of binding rings 43 are fixedly connected to the end of the cleaning brush 42; a spring piece 44 is fixedly connected to the end of the binding ring 43; during operation, the binding rings 43 are installed at the end of the cleaning brush 42 to bind the cleaning brush 42, reducing the problem of the cleaning brush 42 getting tangled when the cleaning plate 41 drives the cleaning brush 42 to rotate; and the spring piece 44 is installed at the end of the binding ring 43 to space between the binding ring 43 and the cleaning brush 42, thereby increasing the cleaning area of ​​the cleaning brush 42.

[0029] Furthermore, such as Figures 1-2 As shown, the bottom of the support plate 1 is fixedly connected with a support leg 5, and there are several of them; during operation, by installing the support leg 5 at the bottom of the support plate 1, the stability of the support plate 1 and the hydrogen sulfide tail gas treatment tank 21 in treating hydrogen sulfide tail gas is improved.

[0030] Working principle: When hydrogen sulfide exhaust gas needs to be treated, the exhaust gas emission device is connected to the end of the exhaust gas inlet pipe 22 to discharge the exhaust gas into the hydrogen sulfide exhaust gas treatment tank 21. Then, absorbent is introduced into the absorbent inlet pipe 24, and then flows through the absorbent inlet pipe 24 into the sealed box 25, and then into the rotating pipe 26. Then, the motor 23 is turned on, and the output end of the motor 23 drives the rotating pipe 26 to rotate at the bottom of the sealed box 25, so that during the rotation of the rotating pipe 26, the exhaust hole is opened. The rotating tube 27 rotates and opens to both sides due to the centrifugal force. The absorbent inside the rotating tube 26 is then sprayed outwards through the discharge hole 27, evenly absorbing and mixing the exhaust gas inside the hydrogen sulfide exhaust gas treatment tank 21 for effective absorption. The exhaust gas is then further purified by the filter screen 35, improving the treatment effect. During the rotation of the rotating tube 26, the pull rope 29 and the gravity ball 31 rotate, and under the influence of centrifugal force, the gravity ball 31 is pulled towards its end. The rotating pipe 26 rotates the sealing plate 28 towards its end, allowing it to open quickly and enabling the absorbent to be sprayed and absorbed through the discharge hole 27. As the rotating pipe 26 rotates, it also rotates the guide rod 32 and the stirring rod 33, agitating and dispersing the absorbent for more even spraying. Furthermore, the rotation of the rotating pipe 26 causes the cleaning plate 41 to rotate, allowing the cleaning brush 42 to adhere to the surface of the filter screen 35 for cleaning, reducing the accumulation of impurities during filtration. To address the clogging issue, a restraining ring 43 is installed at the end of the cleaning brush 42 to restrain the brush 42, reducing the problem of the brushes 42 becoming entangled when the cleaning plate 41 rotates. A spring piece 44 is then installed at the end of the restraining ring 43 to space the restraining ring 43 and the cleaning brush 42, thereby increasing the cleaning area of ​​the brush 42. Support legs 5 are installed at the bottom of the support plate 1 to improve the stability of the support plate 1 and the hydrogen sulfide tail gas treatment tank 21 during hydrogen sulfide tail gas treatment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
