Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization tower cleaning, in particular to a spray structure for a desulfurization tower. Background Art

[0002] A desulfurization tower is a device used to remove sulfur dioxide and other sulfides from industrial waste gas. The sulfur dioxide in the waste gas reacts with the desulfurizer, where it is absorbed and converted into sulfites or sulfates. After desulfurization, the waste gas continues to rise, passes through a demister to remove water mist, and is discharged from the top of the tower.

[0003] When treating exhaust gas from a desulfurization tower, the spray device in most equipment has a relatively fixed spray direction, which cannot effectively cover all areas. Dead zones may form in certain areas of the tower, where the exhaust gas has almost no contact with the spray liquid, resulting in a significant reduction in the contact area between the exhaust gas and the spray liquid. As a result, much of the exhaust gas cannot fully come into contact with the desulfurizer, thereby reducing the removal efficiency of sulfides such as sulfur dioxide. During the desulfurization process, some solid particles, sediments, and unreacted desulfurizer will gradually settle to the bottom of the desulfurization tower. These materials will continue to accumulate on the bottom wall, causing the bottom wall to gradually increase in height, reducing the effective volume of the desulfurization tower and causing slurry to accumulate in the tower, affecting the desulfurization reaction and requiring shutdown for manual cleaning, which increases maintenance costs and downtime.

The internal top of the tower body 1 is fixedly connected to a support ring 9, and the left and right ends of the first connecting pipe 8 are connected to the interior of the support ring 9. By fixing the first connecting pipe 8 in the interior of the support ring 9, the first connecting pipe 8 is fixed to the interior of the tower body 1 through the support ring 9, and the first connecting pipe 8 is supported and fixed to spray the interior of the tower body 1. The outside of the first connecting pipe 8 is connected to a spray pipe 10, and the front and rear ends of multiple spray pipes 10 are fixedly connected to the interior of the support ring 9. The bottoms of multiple spray pipes 10 are connected to internal threads. The pipe 11 evenly distributes the water in the interior of the multiple spray pipes 10 through the first connecting pipe 8, and the water flows into the interior of the internal threaded pipe 11 through the spray pipe 10.

The interiors of the multiple nozzles 14 are all provided with inclined grooves 15, which are connected to the external threaded pipes 12 through the interior of the internal threaded pipe 11 and support the internal second connecting pipes 13. In addition, water will be sprayed out through the inclined grooves 15 on the nozzles 14 after the connection. While spraying water, The pressure passes through the inclined groove 15 in the nozzle 14 to push the nozzle 14 and the second connecting pipe 13 to rotate inside the external threaded tube 12, thereby achieving the effect of rotary spraying to cover the interior of the tower body 1 in all directions. The left side wall of the water tank 3 is connected to the second delivery pipe 16, and the left side wall of the second delivery pipe 16 is connected to the right side wall of the bottom box 2. It is fixed to the inside of the bottom box 2 and the water tank 3 through the second delivery pipe 16.

[0031] like Figure 1 - Figure 10As shown, the left side wall of the tower body 1 is connected with a feed pipe 18, which is connected to an external pipeline through the feed pipe 18 to transfer the gas to the interior of the tower body 1 for treatment. The top of the tower body 1 is connected with an outlet pipe 17, which is used to discharge the treated gas and transfer it to the next device. The interior of the bottom box 2 is fixedly connected with a guide plate 19, which is used to collect and guide impurities, etc. The bottom of the bottom box 2 is fixedly connected with a base 20, which is used to carry out the bottom of the whole. The bottom of the bottom box 2 is supported by a protective box 21, and a motor 22 is arranged inside the protective box 21. The motor 22 is protected on the outside by the protective box 21, and the motor 22 is fixed to the bottom of the bottom box 2. The output end of the motor 22 is fixedly connected to a rotating rod 23, and the top outside of the rotating rod 23 passes through the bottom box 2 and the guide plate 19 and is fixedly connected to a fixing ring 24. The rotating rod 23 is driven to rotate on the top of the guide plate 19 by the output end of the motor 22, and the fixing ring 24 is used to prevent the device on the outside of the rotating rod 23 from falling.

[0032] like Figure 1 - Figure 10 As shown, a first connecting ring 25 is fixedly connected to the outer side of the top of the rotating rod 23, and a connecting rod 26 is fixedly connected to the outer side of the first connecting ring 25. The other ends of the four connecting rods 26 are fixedly connected to a first scraper 27. The first scraper 27 is arranged on the outer side of the upper side wall of the guide plate 19, and is connected to the connecting rod 26 through the first connecting ring 25 on the rotating rod 23, and is connected to the first scraper 27 through the connecting rod 26, and drives the first scraper 27 to rotate around the outer periphery of the upper side wall of the guide plate 19 to scrape impurities on the outer periphery of the upper side wall of the guide plate 19. Flowing into the middle of the guide plate 19, and to prevent impurities and the like from remaining in the dead corner of the guide plate 19 and being unable to be processed, a second connecting ring 28 is fixedly connected to the outer side of the middle part of the rotating rod 23, and a second scraper 29 is fixedly connected to the outer side of the second connecting ring 28. The second scraper 29 is arranged in the middle of the upper side wall of the guide plate 19, and is connected to the second scraper 29 through the second connecting ring 28 on the outer side of the rotating rod 23, and drives the second scraper 29 to rotate on the middle part of the guide plate 19 to scrape the impurities and the like on the guide plate 19 and flow into the interior of the leakage pipe 30.

[0033] like Figure 1 - Figure 10As shown, a leakage pipe 30 is connected to the middle of the guide plate 19, and the bottom end of the leakage pipe 30 is connected to a sewage pipe 31. The other end of the sewage pipe 31 is connected to the left side wall of the bottom box 2. The bottom end of the rotating rod 23 is rotatably connected to the inside of the sewage pipe 31 and the leakage pipe 30. Impurities are transferred to the inside of the sewage pipe 31 through the leakage pipe 30, and the impurities are discharged from the inside of the bottom box 2. The bottom end of the rotating rod 23 is rotatably connected to the inside of the sewage pipe 31 and the leakage pipe 30, which ensures the stability of the rotating rod 23 during the rotation process, and does not affect the normal sewage discharge function of the sewage pipe 31.

[0034] It should be noted that the present invention is a spray structure for a desulfurization tower. First, the motor 22 and the pump 5 are connected to an external power source to supply power to the device.

[0035] During the desulfurization process, bottom tank 2, located at the bottom of tower body 1, collects and temporarily stores treated liquid. Water tank 3, located to the right of bottom tank 2 and tower body 1, stores external water for ready use. After pump 5 is activated, it draws water from water tank 3 through water inlet pipe 6 and then delivers it through first delivery pipe 7 at the output end. First connecting pipe 8, at the top left end of first delivery pipe 7, remains stable thanks to support ring 9. First connecting pipe 8 distributes the water to multiple spray pipes 10 connected to it.

[0036] The front and rear ends of the spray pipe 10 are also fixed by the support ring 9 to ensure that its position in the tower body 1 is stable. The internal threaded tube 11 at the bottom of the spray pipe 10 is connected to the external threaded tube 12 by a thread, so that the nozzle 14 is easy to install and disassemble. When the nozzle 14 needs to be replaced or repaired, the external threaded tube 12 can be easily unscrewed for operation.

[0037] The second connecting pipe 13 inside the externally threaded pipe 12 guides water to the nozzle 14. The inclined groove 15 inside the nozzle 14 makes the water sprayed out at a specific angle and direction. When the water flows out through the inclined groove 15 on the nozzle 14, the different water pressures drive the nozzle 14 and the second connecting pipe 13 to rotate inside the externally threaded pipe 12, thereby achieving the effect of rotating water spraying, and comprehensively covering the interior of the tower body 1.

[0038] When motor 22 is started, its output drives rotating rod 23 to rotate. A fixing ring 24, which extends through the outer top of rotating rod 23 and connects to bottom box 2 and guide plate 19, further stabilizes rotating rod 23. A first connecting ring 25, connected to a connecting rod 26 and a first scraper 27, located on the outer top of rotating rod 23, rotates as rotating rod 23 rotates. First scraper 27, located on the outer side of the upper sidewall of guide plate 19, scrapes away solid particles, sediment, and other impurities that may accumulate on the outer edge of guide plate 19, preventing these impurities from accumulating and affecting the normal diversion function of guide plate 19 and the flow of water within bottom box 2. It also drives impurities on the periphery to flow into the center.

[0039] A second scraper 29 connected to a second connecting ring 28 on the outer side of the middle portion of the rotating rod 23 is disposed in the middle portion of the upper sidewall of the guide plate 19. The second scraper 29 also removes any accumulated material from the middle portion of the guide plate 19 during rotation, ensuring a clean upper surface of the guide plate 19 and maintaining a good diversion effect.

[0040] The guide plate 19 guides the water flow throughout the structure, ensuring an orderly flow of liquid within the bottom tank 2. A drainage pipe 30, extending through the middle of the guide plate 19, and a drain pipe 31, connected to its bottom end, are used to drain accumulated impurities and sediment within the bottom tank 2. The bottom end of the rotating rod 23 is rotatably connected to the drain pipe 31 and the drainage pipe 30, ensuring the stability of the rotating rod 23 during rotation without affecting the normal drainage function of the drain pipe 31.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
