Description

Technical Field

[0001] This utility model relates to the field of desulfurization nozzle technology, and in particular to a desulfurization nozzle that avoids clogging. Background Technology

[0002] A desulfurization nozzle is a solid or hollow cone-shaped spray device with anti-clogging properties. It forms a mist spray through the tangential collision of spiral surfaces. The streamlined cavity design significantly reduces the drag coefficient, and the compact structure combined with the unobstructed flow channel design can minimize liquid blockage. It is mainly used in exhaust gas scrubbing, gas cooling, flue gas desulfurization and dust removal systems, especially in the flue gas desulfurization and dust removal industry.

[0003] Desulfurization nozzles are key components in flue gas desulfurization systems, primarily used to atomize the desulfurization liquid and ensure sufficient contact with the flue gas to improve desulfurization efficiency. Clogged desulfurization nozzles are a common malfunction in desulfurization systems. Impurities such as gypsum flakes and corrosion-resistant scale in the desulfurization slurry are the main sources of clogging. Poor coal quality and limestone quality (e.g., high impurity content) can also exacerbate clogging. Therefore, a desulfurization nozzle designed to prevent clogging is proposed to avoid problems such as decreased desulfurization liquid spray density and uneven spraying. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a desulfurization nozzle that avoids clogging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A desulfurization nozzle designed to prevent clogging includes a nozzle. A guide tube is fixedly installed at the inlet end of the nozzle, and a nozzle is fixedly installed at the outlet end. The guide tube has a threaded top edge on its outer circumference. A first annular groove is provided at the upper end of the inner circumference of the guide tube, a second annular groove at the lower end of the inner circumference of the guide tube, and a third annular groove at the upper end of the inner circumference of the nozzle. A first ring is rotatably engaged inside the first annular groove, a second ring is rotatably engaged inside the second annular groove, and a third ring is rotatably engaged inside the third annular groove. Multiple equally spaced adhesive rods are fixedly connected between the inner sides of the second and third annular rings. A bracket is fixedly installed between the inner sides of the second annular rings, and a rotating shaft is fixedly sleeved in the middle of the bracket. Scrapers are fixedly installed on the outer sides of the spaced adhesive rods. An upper sleeve rod is fixedly installed between the top edge of the adhesive rod located between two scrapers and the inner side of the first annular ring. A lower sleeve rod is fixedly installed at the bottom edge of the adhesive rod located between two scrapers. Elastic scrapers are sleeved around the circumferences of both the upper and lower sleeve rods.

[0007] Preferably, the adhesive rod is located at the connection between the nozzle and the guide tube.

[0008] Preferably, the top edge of the rotating shaft is provided with multiple driven blades and multiple drive fan blades.

[0009] Preferably, the elastic scraper includes a support sleeve, and a triangular scraper is provided on the outer side of the support sleeve. Multiple elastic columns are fixedly connected to the opposite ends of the triangular scraper and the support sleeve.

[0010] Preferably, the elastic scraper and the scraper blade are arranged alternately.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model proposes a desulfurization nozzle that avoids clogging. A first ring is rotatably engaged inside a first annular groove, a second ring is rotatably engaged inside a second annular groove, and a third ring is rotatably engaged inside a third annular groove. Multiple equally spaced adhesive rods are fixedly connected between the inner circumferences of the second and third rings. Scrapers are fixedly mounted on the outer circumferences of the spaced adhesive rods. Elastic scrapers are fitted around the circumferences of both the upper and lower sleeve rods. When desulfurization slurry is introduced into the nozzle from the conduit, the slurry continuously impacts multiple driven blades, causing the rotating shaft to rotate, which in turn drives the transmission fan blades to rotate. The first ring rotates inside the first annular groove, the second ring rotates inside the second annular groove, and the third ring rotates inside the third annular groove. This causes the multiple scrapers and elastic scrapers to rotate and adhere to the inner walls of the nozzle and conduit, scraping away and cleaning the slurry residue that has condensed on the inner walls. This allows the desulfurization nozzle to efficiently atomize the desulfurization slurry, ensuring full contact with the flue gas and improving the desulfurization effect.

[0013] 2. The present invention proposes a desulfurization nozzle that avoids clogging. By placing the stick and scraper at the connection between the nozzle and the guide pipe, the scraper fits against the inner side of the connection between the nozzle and the guide pipe, which facilitates the scraper to remove the slurry residue that has solidified on the inner wall. In addition, the triangular scraper and the support sleeve of the elastic scraper are fixedly connected to multiple elastic columns at opposite ends, which allows the elastic scraper to flexibly pass over the slurry residue that is firmly adhered to the inner wall of the nozzle and the guide pipe, reducing the difficulty of rotating the rotating shaft.

[0019] Reference Figure 1-4 A desulfurization nozzle designed to prevent clogging includes a nozzle 1, with a guide tube 3 fixedly mounted at the inlet end and a nozzle 2 fixedly mounted at the outlet end. The guide tube 3 has a threaded top on its outer circumferential wall for easy installation and removal from the nozzle. The guide tube 3 has a first annular groove 5 at its upper circumferential wall, a second annular groove 6 at its lower circumferential wall, and a third annular groove 7 at its upper circumferential wall. A first ring 8 is rotatably engaged inside the first annular groove 5, a second ring 9 is rotatably engaged inside the second annular groove 6, and a third ring 10 is rotatably engaged inside the third annular groove 7. Multiple equally spaced adhesive rods 15 are fixedly connected between the inner sides of the second ring 9 and the inner sides of the third ring 10. A bracket 11 is fixedly provided between the inner sides of the second ring 9, and a rotating shaft 12 is fixedly sleeved in the middle of the bracket 11. Scrapers 16 are fixedly provided on the outer sides of the spaced adhesive rods 15. An upper sleeve rod 17 is fixedly installed between the top of the adhesive rod 15 located between two scrapers 16 and the inner side of the first ring 8. A lower sleeve rod 18 is fixedly installed at the bottom of the adhesive rod 15 located between two scrapers 16, and elastic scrapers are sleeved on the circumferences of both the upper sleeve rod 17 and the lower sleeve rod 18.

[0020] In this utility model, the sticking rod 15 is located at the connection between the nozzle 1 and the guide tube 3, so that the sticking rod 15 fits the inner side of the connection between the nozzle 1 and the guide tube 3, thereby facilitating the scraper 16 to scrape off the two kinds of slurry residues that have solidified on the inner wall.

[0021] The rotating shaft 12 has multiple driven blades 13 at its circumference and multiple drive blades 14 at its circumference. The desulfurization slurry is introduced into the nozzle 1 through the conduit 3. The desulfurization slurry continuously impacts the multiple driven blades 13, causing the rotating shaft 12 to rotate, which in turn drives the drive blades 14 to rotate. The first ring 8 rotates inside the first annular groove 5, the second ring 9 rotates inside the second annular groove 6, and the third ring 10 rotates inside the third annular groove 7. This causes multiple scrapers 16 and elastic scrapers to rotate in contact with the inner wall of the nozzle 1 and the conduit 3, thereby scraping away and cleaning the slurry residue that has condensed on the inner wall. This allows the desulfurization nozzle to efficiently atomize the desulfurization slurry, making full contact with the flue gas to improve the desulfurization effect.

[0022] The elastic scraper includes a support sleeve 19, and a triangular scraper 20 is provided on the outside of the support sleeve 19. Multiple elastic columns 21 are fixedly connected to the opposite ends of the triangular scraper 20 and the support sleeve 19, so that the elastic scraper can flexibly pass over the slurry residue that is firmly bonded to the inner wall of the nozzle 1 and the inner wall of the guide tube 3, reducing the difficulty of rotating the rotating shaft 12.

[0023] The alternating arrangement of the elastic scraper and the scraper blade 16 makes it difficult for the desulfurization slurry to solidify on its surface.

[0024] Working principle: A first ring 8 is rotatably engaged inside the first annular groove 5, a second ring 9 is rotatably engaged inside the second annular groove 6, and a third ring 10 is rotatably engaged inside the third annular groove 7. Multiple equally spaced sticking rods 15 are fixedly connected between the inner circumferences of the second ring 9 and the third ring 10, and scraper blades 16 are fixedly provided on the outer circumferences of the spaced sticking rods 15. Elastic scrapers are fitted around the circumferences of the upper sleeve rod 17 and the lower sleeve rod 18. When the desulfurization slurry is introduced into the nozzle 1 from the conduit 3, the desulfurization slurry can be continuously... The continuous impact of multiple driven blades 13 causes the rotating shaft 12 to rotate, which in turn drives the transmission fan blades 14 to rotate. The first ring 8 rotates inside the first annular groove 5, the second ring 9 rotates inside the second annular groove 6, and the third ring 10 rotates inside the third annular groove 7. This causes multiple scrapers 16 and elastic scrapers to rotate in contact with the inner wall of the nozzle 1 and the guide tube 3, thereby scraping away and cleaning the slurry residue that has condensed on the inner wall. This allows the desulfurization nozzle to efficiently atomize the desulfurization slurry, making it fully contact the flue gas to improve the desulfurization effect.

[0025] By positioning the stick 15 and scraper 16 at the connection between the nozzle 1 and the guide tube 3, the scraper 16 fits against the inner side of the connection between the nozzle 1 and the guide tube 3, making it easier for the scraper 16 to scrape off the two types of slurry residue that have solidified on the inner wall. In addition, the triangular scraper 20 of the elastic scraper and the support sleeve 19 are fixedly connected to each other with multiple elastic columns 21, so that the elastic scraper can flexibly pass over the slurry residue that is firmly bonded to the inner wall of the nozzle 1 and the inner wall of the guide tube 3, reducing the difficulty of rotating the rotating shaft 12.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
