[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 4 , the utility model provides a technical solution:

[0027] A vaporization device for producing energy-saving high-purity reagent ammonia water comprises a base plate 1, the upper end of the base plate 1 is fixedly connected to a slide rod 11 and a fin tube 21, and the number of the slide rods 11 is four, and the number of the fin tube 21 is multiple, the lower end of the base plate 1 is fixedly connected to a support seat 12 on all sides, the upper ends of the four slide rods 11 are fixedly connected to a top plate 2, the upper and lower ends and the left side of the base plate 1 are jointly provided with a defrost assembly 4, the defrost assembly 4 comprises a scraper 43 movably connected to the upper end of the base plate 1, the left end of the scraper 43 is fixedly connected to a fixed block 431, and the number of the fixed block 431 is two groups, characterized in that: the defrost assembly 4 also comprises a motor 41 fixedly connected to the lower end of the base plate 1, the left end of the output shaft of the motor 41 It is fixedly connected with a driving gear 411, and the left end of the bottom plate 1 and the left end of the top plate 2 are movably connected with a reel 42, and the number of the reels 42 is four. The left side of the reel 42 at the front end of the left side of the bottom plate 1 is fixedly connected with a driven gear 421, and the two groups of fixed blocks 431 and the two groups of reels 42 are movably connected with a connecting rope 44, and the connecting rope 44 is S-shaped and surrounds the two reels 42. The upper and lower ends of the multiple fin tubes 21 are fixedly connected with a connecting pipe 22, and the upper ends of the multiple fin tubes 21 at the rear end are fixedly connected with an air collecting cylinder 3, and the rear end of the air collecting cylinder 3 is fixedly connected with an exhaust pipe 31. The sliding rod 11 and the fin tube 21 both pass through the scraper 43, and the gap between the scraper 43 and the multiple fin tubes 21 is 5mm.

[0028] By adopting the above technical solution, the device is fixed by the support seat 12. When the vaporization work for ammonia production is carried out, liquid ammonia is injected through the water inlet pipe 511 at the front end of the guide tube 51, and the liquid ammonia continuously enters the interior of the multiple finned tubes 21 through the connecting pipe 22 at the lower end. The liquid ammonia inside the finned tubes 21 at the lower end of the top plate 2 is heated by an external heat source, and the heat is transferred to the liquid ammonia, causing its temperature to rise and begin to vaporize. The vaporized ammonia passes through the multiple finned tubes 21 at the rear end and enters the interior of the gas collecting cylinder 3, and is finally discharged through the exhaust pipe 31. In the process of liquid ammonia vaporization, the liquid ammonia temperature rises and the vaporized liquid is converted into gas, thereby absorbing the heat of the surrounding environment. In this process, the temperature of the surface of the multiple finned tubes 21 decreases, causing water vapor in the surrounding air to adhere to the outside of the multiple finned tubes 21 and condense into frost. At this time, the motor 41 is started, and the motor 41 is started so that the output shaft and the driving gear 411 at the left end are rotated together. The spool 42 is rotated so that the driving gear 411 rotates and the engagement with the driven gear 421 drives the reel 42 at the right end of the driven gear 421 to rotate. The rotation of the reel 42 drives the connecting rope 44 to move from left to right. The connecting rope 44 fixed to the fixed block 431 on the right side is continuously reduced, and the scraper 43 at the lower end is driven to move upward through the slide bar 11. The scraper 43 moves upward and continuously scrapes the frost on the outside of the fin tube 21, thereby achieving the purpose of cleaning the frost. When the driving gear 411 continuously drives the driven gear 421 to rotate through the empty tooth position of the driven gear 421, the driving gear 411 cannot transmit the driven gear 421. At this time, the scraper 43 moves vertically downward under the influence of gravity and returns to the original position, which is convenient for the next cleaning work, so as to achieve the purpose of scraping and cleaning the fin tube 21, thereby avoiding the frost layer formed by frost to increase additional thermal resistance, resulting in a significant decrease in the heat transfer performance of the vaporizer, thereby affecting the overall working efficiency.

[0029] Specifically, such as Figure 4 As shown, a quantity control component 5 is provided at the lower end of the front end multiple fin tubes 21. The quantity control component 5 includes a guide tube 51 fixedly connected to the lower end of the front end fin tube 21. The rear end of the guide tube 51 is respectively connected to the two ends of the multiple fin tubes 21. The front end of the guide tube 51 is fixedly connected to the water inlet pipe 511. The front end of the inner part of the guide tube 51 is provided with a branch groove 52. The rear end of the branch groove 52 is provided with a feed port 531, and the number of the feed ports 531 is five. The rear end of the feed port 531 is provided with a first guide groove 53, and the rear end of the first guide groove 53 is provided with a second guide groove 532. The rear end of the second guide groove 532 is fixedly connected with a blocking rod 533. The interior of the multiple first guide grooves 53 is provided with a blocking ball 54. The diameter of the feed port 531 is smaller than the diameter of the first guide groove 53, and the diameter of the first guide groove 53 is smaller than the diameter of the second guide groove 532. The blocking ball 54 slides and fits inside the first guide groove 53.

[0030] By adopting the above technical solution, before the liquid ammonia vaporization work is carried out, liquid ammonia is injected into the water inlet pipe 511 at the front end of the guide tube 51, and the liquid ammonia enters the sub-slot 52 through the water inlet pipe 511. The liquid ammonia in the sub-slot 52 is then continuously injected and enters the first guide groove 53 through the feed port 531 respectively. As the liquid ammonia is continuously injected, the blocking ball 54 is pushed to move inside the first guide groove 53, thereby entering the second guide groove 532 and stopping when it contacts the blocking rod 533. The liquid ammonia passes through the gap between the blocking ball 54 and the second guide groove 532. When the fin tube 21 is filled with a certain amount of liquid ammonia, the gravity of the liquid ammonia pushes the blocking ball 54 toward the feed port 531. When the blocking ball 54 moves to the feed port 531, the purpose of closing the feed port 531 is achieved, thereby increasing the time that the liquid ammonia exists in the device, and allowing the liquid ammonia to fully vaporize and react in the fin tube 21.

[0031] Working principle: During the vaporization process of liquid ammonia, the temperature of liquid ammonia rises and the vaporized liquid is converted into gas, thereby absorbing the heat of the surrounding environment. In this process, the surface temperature of the multiple fin tubes 21 decreases, causing the water vapor in the surrounding air to adhere to the outside of the multiple fin tubes 21 and condense into frost. At this time, the motor 41 is started, and the motor 41 is started to rotate together with the driving gear 411 at the left end. The driving gear 411 rotates and drives the reel 42 at the right end of the driven gear 421 to rotate through the engagement between the driving gear 411 and the driven gear 421. The rotation of the reel 42 drives the connecting rope 44 to move from left to right, and the connecting rope 44 fixed to the fixed block 431 on the right side is constantly rotating. When the speed is reduced, the scraper 43 at the lower end moves upward through the slide bar 11, and the scraper 43 moves upward to continuously scrape the frost on the outside of the fin tube 21, thereby achieving the purpose of cleaning the frost. When the driving gear 411 continuously drives the driven gear 421 to rotate through the empty tooth position of the driven gear 421, the driving gear 411 cannot transmit the driven gear 421. At this time, the scraper 43 moves vertically downward under the influence of gravity, and then returns to the original position, which is convenient for the next cleaning work, so as to achieve the purpose of scraping and cleaning the fin tube 21, thereby avoiding the frost layer formed by frost to increase additional thermal resistance, resulting in a significant decrease in the heat transfer performance of the vaporizer, and thus affecting the overall work efficiency.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
