A two-phase ammonia spraying device suitable for liquid ammonia and gaseous ammonia

Abstract

This utility model discloses a two-phase ammonia injection device suitable for liquid ammonia and gaseous ammonia, including a main pipe, a connecting pipe, a nozzle, and a retaining ring structure. When installing the nozzle, the nozzle is connected to the connecting pipe, causing the main pipe to be secured in the fixing plate. Then, the pressure ring is rotated, causing two pressure rings to press against the main pipe. Next, the retaining plate is rotated, causing the retaining plate to press against the surface of the second pressure block. Then, the screw is rotated; because the retaining plate and screw are threaded together, the retaining plate moves and pushes against the second pressure block as the screw rotates, allowing the two pressure rings to press tightly against the main pipe. At this point, the retaining head is secured in the retaining groove, achieving the beneficial effect of convenient installation. When disassembling, rotating the screw causes the retaining plate to slide and release the pressure on the second pressure block. Then, rotating the retaining ring releases the restriction on the nozzle.

Description

Technical Field

[0001] This utility model relates to the field of liquid ammonia and gaseous ammonia two-phase ammonia injection technology, specifically to a device suitable for liquid ammonia and gaseous ammonia two-phase ammonia injection. Background Technology

[0002] Two-phase ammonia injection technology, which combines liquid ammonia and gaseous ammonia, is a key component in industrial denitrification. Its core lies in the precise control of the ammonia supply form and mixing effect. This technology requires the use of an ammonia injection device.

[0003] The existing ammonia injection system has the following problems: Existing ammonia injection devices are prone to nozzle blockage due to impurities or crystals after long-term use, requiring regular maintenance and cleaning. Maintenance and cleaning require disassembling the nozzles, but disassembling the existing nozzles is inconvenient, leading to maintenance inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a two-phase ammonia injection device suitable for liquid ammonia and gaseous ammonia, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a two-phase ammonia injection device suitable for liquid ammonia and gaseous ammonia, comprising a main pipe, a connecting pipe provided on the main pipe, a nozzle provided on the connecting pipe, a retaining ring structure provided on the nozzle, the retaining ring structure comprising a fixing plate, two fixing plates provided on the nozzle, a pressure ring connected to the fixing plate, a pressure block provided on one of the pressure rings, a retaining seat connected to the pressure block, a retaining plate provided on the retaining seat, a retaining head provided on the retaining plate, and a second pressure block provided on the other end of the pressure ring, the second pressure block being provided with a retaining groove.

[0006] Preferably, a screw is connected to the pressure block, and the clamping plate is disposed on the screw.

[0007] Preferably, the card plate is located inside the pressure block, and the card plate is slidably connected to the pressure block.

[0008] Preferably, the tails of the pressing block and the second pressing block are elastic, and the tails bend when the pressing block and the second pressing block are in their natural unforced state.

[0009] Preferably, the upper end of the fixing plate is elastic, and the distance between the two fixing plates is smaller than the diameter of the main pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: When installing the nozzle, align the nozzle with the connecting pipe so that the main pipe is secured in the fixing plate. Then, rotate the pressure ring to press the two pressure rings onto the main pipe. Next, rotate the retainer to press the retaining plate onto the surface of the second pressure block. Then, rotate the screw. Since the retaining plate and the screw are threaded together, the retaining plate moves and pushes the second pressure block as the screw rotates, so that the two pressure rings can be tightly pressed onto the main pipe. At this point, the retaining head is engaged in the retaining groove, achieving the beneficial effect of convenient installation. When disassembling, rotate the screw to allow the retaining plate to slide and release the pressure on the second pressure block. Then, rotate the retaining ring to release the restriction on the nozzle. Attached Figure Description

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figure 1 and Figure 2 This utility model provides a two-phase ammonia injection device suitable for liquid ammonia and gaseous ammonia, including a main pipe 1, a connecting pipe 2 on the main pipe 1, a nozzle 3 on the connecting pipe 2, and a retaining ring structure 4 on the nozzle 3.

[0020] Specifically, the main pipe 1 is a two-phase controller. The two-phase controller mixes liquid ammonia and gaseous ammonia in a certain proportion and injects them into the main pipe 1. Then, the two-phase ammonia is injected through the connecting pipe 2 and the nozzle 3.

[0021] Please see Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a two-phase ammonia injection device suitable for liquid ammonia and gaseous ammonia. The retaining ring structure 4 includes a fixing plate 41. The top of the nozzle 3 is equipped with a fixing plate 41. There are two fixing plates 41, which are symmetrically fixed on the top of the nozzle 3. The two fixing plates 41 are rotatably connected to a pressure ring 42. One of the pressure rings 42 is fixed with a pressure block 43. The pressure block 43 is rotatably connected with a retaining seat 44. The retaining seat 44 is provided with a retaining plate 45. The retaining plate 45 is provided with a retaining head 46. The other end of the pressure ring 42 is provided with a second pressure block 47. The second pressure block 47 is provided with a retaining groove 48.

[0022] The pressure block 43 is rotatably connected to a screw 49, and a clamping plate 45 is threadedly connected to the screw 49. The clamping plate 45 is located inside the pressure block 43 and is slidably connected to the pressure block 43, which is used to limit the position of the clamping plate 45.

[0023] The tails of the pressing blocks 43 and 47 are elastic. When the pressing blocks 43 and 47 are in their natural unforced state, their tails bend, so that when the pressing blocks 43 and 47 press on the main pipe 1, they will be subjected to force and press on the main pipe 1.

[0024] The upper end of the fixing plate 41 is elastic, and the distance between the two fixing plates 41 is smaller than the diameter of the main pipe 1, so that when the main pipe 1 is fixed in the fixing plate 41, the main pipe 1 can be pressed tightly.

[0025] Specifically, when installing the nozzle 3, connect the nozzle 3 to the connecting pipe 2 so that the main pipe 1 is locked in the fixing plate 41. Then rotate the pressure ring 42 so that the two pressure rings 42 press on the main pipe 1. Then rotate the clamping seat 44 so that the clamping plate 45 presses on the surface of the second pressure block 47. Then rotate the screw 49. Since the clamping plate 45 is threadedly connected to the screw 49, the clamping plate 45 moves and pushes the second pressure block 47 when the screw 49 rotates, so that the two pressure rings 42 can be tightly pressed on the main pipe 1. At this time, the clamping head 46 is locked in the clamping groove 48, which achieves the beneficial effect of convenient installation. When disassembling, rotate the screw 49 so that the clamping plate 45 slides to release the pressure on the second pressure block 47. Then rotate to open the pressure ring 42 to release the limitation on the nozzle 3.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
