Abstract
Description
Technical Field
[0001] This utility model relates to the field of ammonia vaporization technology, and more specifically, to an ammonia vaporization device for ammonia water. Background Technology
[0002] Ammonia vaporization refers to the process by which liquid ammonia absorbs heat and transforms into a gaseous state. When the temperature rises, the ammonia molecules in the ammonia solution break free from their bonds to the liquid surface and gradually evaporate into gas, while some of the water evaporates. This process is accompanied by a significant endothermic effect, requiring external energy to overcome intermolecular forces. The vaporized ammonia gas mixes with steam, causing a rapid expansion in volume, and can be used in refrigeration, chemical synthesis, and other fields.
[0003] Chinese patent document CN208471553U discloses a novel ammonia vaporization device, which uses an inner and outer sleeve to isolate and transport high-temperature steam into the tank, thereby enhancing the contact effect with ammonia and improving the ammonia vaporization efficiency. However, by using an inner and outer sleeve, the high-temperature steam is input through the inner sleeve and discharged through the gap between the inner and outer sleeves. During this process, the input high-temperature steam cannot directly contact the ammonia to achieve heat exchange, resulting in heat loss and affecting the heat exchange effect of the steam, thus affecting the ammonia vaporization efficiency.
[0004] In addition, Chinese patent document CN215326965U discloses an ammonia vaporization device for ammonia water, which achieves ammonia water vaporization by using non-spraying and hot air heating. However, when the above scheme is used, external hot air needs to be introduced, which will lead to a decrease in the concentration of ammonia gas formed after ammonia water vaporization. Furthermore, if there are impurities in the introduced hot air, it will also cause ammonia gas pollution and affect the quality of ammonia gas formed after ammonia water vaporization. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] In view of the problems existing in the prior art, this utility model provides an ammonia vaporization device for ammonia water, so as to solve the technical problems of poor efficiency and poor effect of the ammonia vaporization device for ammonia water mentioned in the background art.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] An ammonia vaporization device for ammonia water includes a tank. A partition plate is provided at the bottom of the tank's interior, dividing the tank into a steam conveying chamber and a vaporization chamber. A spiral guide channel is provided within the steam conveying chamber, with its input end extending to the outside of the tank and connected to a steam input pipe. An outer spiral heat exchange tube is provided within the vaporization chamber, its bottom end connected to the center of the spiral guide channel. An inner spiral heat exchange tube is provided inside the outer spiral heat exchange tube, its top end connected to the tail end of the outer spiral heat exchange tube, and its bottom end extending to the outside of the tank and connected to a steam discharge pipe. An ammonia water inlet pipe is provided at the top of the tank, extending into the tank and connected to a spray structure. An ammonia gas discharge pipe is provided at the top of the tank.
[0010] This utility model is further configured such that the spray structure includes multiple spray pipes arranged in a ring array on the inner wall of the tank. Each spray pipe is equipped with multiple atomizing nozzles. A liquid inlet conveying structure is provided between the spray pipes and the ammonia inlet pipe, allowing the ammonia to be sprayed out through the cooperation of the spray pipes and atomizing nozzles, and onto the surfaces of the outer and inner spiral heat exchange tubes. This ensures that the ammonia comes into contact with the high-temperature outer and inner spiral heat exchange tubes, achieving heating and evaporation, and thus vaporizing the ammonia. To achieve rapid vaporization of ammonia water, the amount of ammonia water is controlled to exceed the amount of vaporization that occurs on the surfaces of the outer and inner spiral heat exchange tubes. This allows the excess ammonia water to fall to the bottom of the vaporization chamber after preheating through contact with the outer and inner spiral heat exchange tubes. The ammonia water accumulated at the bottom of the vaporization chamber can then be vaporized through heat exchange between the high-temperature steam in the spiral guide channel and the partition plate. This improves the thermal conversion efficiency and completeness of the steam when heating and vaporizing ammonia water, thereby enhancing the vaporization effect and efficiency of ammonia water.
[0011] The present invention is further configured such that the liquid inlet conveying structure includes an annular conveying pipe, the outer side of which is connected to the ammonia water inlet pipe, and the inner side of which is connected to each of the spray pipes. The connection between the ammonia water inlet pipe and the spray pipe is realized through the cooperation of the annular conveying pipe and the connecting pipe, thereby realizing the supply of ammonia water.
[0012] The present invention is further configured such that the annular conveying pipe is located on the outside of the tank body, and a preheating pipe is provided on the outside of the annular conveying pipe. The preheating pipe is serpentine and wrapped around the outside of the annular conveying pipe. The input end of the preheating pipe is connected to the steam discharge pipe, and the output end is provided with a steam output pipe. By setting up the preheating pipe and wrapping it in a serpentine shape around the outside of the annular conveying pipe, the steam discharged from the steam discharge pipe can flow along the preheating pipe. The waste heat in the steam can be used to preheat the ammonia water in the annular conveying pipe, thereby improving the vaporization efficiency of the ammonia water after entering the vaporization chamber inside the tank body, and at the same time improving the waste heat utilization rate of the steam.
[0013] The present invention is further configured such that an insulation cover is provided on the outside of the preheating pipe, and insulation cotton is provided inside the insulation cover. The combination of insulation cotton and insulation cover can enhance the external insulation effect of the preheating pipe, thereby improving the heat exchange effect between the preheating pipe and the annular conveying pipe, and improving the utilization effect and efficiency of steam preheating.
[0014] The present invention is further configured such that a pressure relief valve and a pressure detector are provided at the top of the side wall of the tank. The pressure detector can monitor the internal pressure of the tank, and the pressure relief valve can be used to automatically relieve pressure when the internal pressure of the tank is too high.
[0015] The present invention is further provided that a level gauge is provided on the side of the tank body. The level gauge can monitor the level of ammonia water inside the tank body and located in the vaporization chamber, so as to avoid insufficient ammonia water entering the tank body, resulting in insufficient utilization of steam heat energy.
[0016] The present invention is further configured such that a thermometer is provided on the tank body, and the temperature inside the tank body can be monitored by the thermometer. Multiple thermometers can be set at different heights of the tank body, so as to flexibly and accurately monitor the temperature in various areas inside the tank body.
[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides an ammonia vaporization device for ammonia water, which has the following features:
[0019] Beneficial effects:
[0020] 1. Highly efficient heat exchange and gasification effect
[0021] This invention significantly extends the flow path of high-temperature steam within the tank by employing a nested design of outer and inner spiral heat exchange tubes, thereby substantially increasing the heat exchange area. The atomized ammonia water comes into full contact with the surfaces of the outer and inner spiral tubes, achieving rapid heating and vaporization. Simultaneously, excess ammonia water falls to the bottom and undergoes secondary heat exchange through a partition plate, resulting in the simultaneous vaporization of liquid and atomized ammonia water. This dual heat exchange mechanism improves the utilization rate of steam thermal energy, increases vaporization efficiency compared to traditional devices, and ensures stable ammonia concentration after vaporization, avoiding the dilution and cleanliness issues caused by traditional hot air introduction.
[0022] 2. Clean vaporization and concentration assurance
[0023] This device employs a closed-loop heat exchange design, where ammonia water and high-temperature steam exchange heat indirectly through pipe walls and partition plates, eliminating the risk of steam impurities and ammonia mixing with outside air. The spiral guide channel and preheating pipe structure ensure uniform heat transfer, preventing ammonia decomposition due to localized overheating. A spray system, in conjunction with a level gauge, precisely controls the ammonia water input, maintaining a stable liquid level within the vaporization chamber, preventing dry burning and ensuring full utilization of waste heat.
[0024] 3. Waste heat recovery and energy consumption optimization
[0025] This innovative system employs a serpentine preheating pipe wrapped around a ring-shaped delivery pipe, utilizing the waste heat of the discharged steam to preheat the input ammonia water, thus reducing temperature fluctuations within the tank. The combination of an insulation cover and insulation cotton further reduces heat loss in the preheating section, resulting in lower overall energy consumption. Furthermore, the linkage design between the pressure relief valve and the pressure detector ensures operational safety, while multi-point thermometer monitoring ensures accurate temperature control during the vaporization process.

[0036] Please see Figures 1-6 An ammonia vaporization device for ammonia water includes a tank 1. A partition plate 2 is provided at the bottom of the tank 1, dividing the tank 1 into a steam conveying chamber 3 and a vaporization chamber 4. A spiral guide groove 5 is provided in the steam conveying chamber 3. The input end of the spiral guide groove 5 extends to the outside of the tank 1 and is provided with a steam input pipe 6. An outer spiral heat exchange tube 7 is provided in the vaporization chamber 4. The bottom end of the outer spiral heat exchange tube 7 is connected to the center of the spiral guide groove 5. An inner spiral heat exchange tube 8 is provided inside the outer spiral heat exchange tube 7. The top end of the inner spiral heat exchange tube 8 is connected to the tail end of the outer spiral heat exchange tube 7, and the bottom end extends to the outside of the tank 1 and is provided with a steam discharge pipe 9. An ammonia water inlet pipe 10 is provided at the top of the tank 1. The ammonia water inlet pipe 10 extends into the tank 1 and is provided with a spray structure. An ammonia gas discharge pipe 11 is provided at the top of the tank 1.
[0037] Please see Figures 1-6As one implementation of the spray structure: the spray structure includes multiple spray pipes 12 arranged in a ring array on the inner wall of the tank 1. Multiple atomizing nozzles 13 are installed on the spray pipes 12. A liquid inlet conveying structure is provided between the spray pipes 12 and the ammonia inlet pipe 10, allowing ammonia to be sprayed out through the cooperation of the spray pipes 12 and the atomizing nozzles 13, and sprayed onto the surfaces of the outer spiral heat exchange tube 7 and the inner spiral heat exchange tube 8. This allows the ammonia to come into contact with the high-temperature outer spiral heat exchange tube 7 and inner spiral heat exchange tube 8, achieving heating and evaporation, and thus vaporizing the ammonia. This enables rapid vaporization of the ammonia. Simultaneously, the amount of ammonia water is controlled to be greater than the amount of vaporization that comes into contact with the surfaces of the outer spiral heat exchanger tube 7 and the inner spiral heat exchanger tube 8. This allows the excess ammonia water to fall to the bottom of the vaporization chamber 4 after preheating through contact with the outer spiral heat exchanger tube 7 and the inner spiral heat exchanger tube 8. Thus, the ammonia water accumulated at the bottom of the vaporization chamber 4 can be vaporized through heat exchange between the high-temperature steam in the spiral guide channel 5 and the partition plate 2. This improves the thermal conversion efficiency and completeness of the steam when heating and vaporizing the ammonia water, thereby improving the vaporization effect and efficiency of the ammonia water. Here, it is preferable to control the ammonia water supply to be 1.2-1.5 times the theoretical vaporization amount.
[0038] Please see Figures 1-6 As one implementation of the liquid inlet conveying structure: The liquid inlet conveying structure includes an annular conveying pipe 14, the outer side of which is connected to the ammonia water inlet pipe 10, and the inner side of which is connected to each spray pipe 12 by a connecting pipe 15. The connection between the ammonia water inlet pipe 10 and the spray pipe 12 is realized through the cooperation of the annular conveying pipe 14 and the connecting pipe 15, so as to realize the supply of ammonia water.
[0039] In this invention, the annular conveying pipe 14 is located on the outside of the tank body 1, and a preheating pipe 16 is provided on the outside of the annular conveying pipe 14. The preheating pipe 16 is serpentine and wrapped around the outside of the annular conveying pipe 14. The input end of the preheating pipe 16 is connected to the steam discharge pipe 9, and the output end is provided with a steam output pipe 17. By setting the preheating pipe 16 and wrapping the preheating pipe 16 in a serpentine shape around the outside of the annular conveying pipe 14, the steam discharged from the steam discharge pipe 9 can flow along the preheating pipe 16. The waste heat in the steam can be used to preheat the ammonia water in the annular conveying pipe 14, thereby improving the vaporization efficiency of the ammonia water after entering the vaporization chamber 4 inside the tank body 1, and at the same time improving the waste heat utilization rate of the steam.
[0040] This invention provides an insulation cover 18 on the outside of the preheating pipe 16, and insulation cotton 19 inside the insulation cover 18. The combination of insulation cotton 19 and insulation cover 18 can enhance the external insulation effect of the preheating pipe 16, thereby improving the heat exchange effect between the preheating pipe 16 and the annular conveying pipe 14, and improving the utilization effect and efficiency of steam preheating.
[0041] Please see Figures 1-6As one embodiment of the tank body 1: a pressure relief valve 20 and a pressure detector 21 are provided at the top of the side wall of the tank body 1. The pressure detector 21 can monitor the internal pressure of the tank body 1, and the pressure relief valve 20 can be used to automatically relieve pressure when the internal pressure of the tank body 1 is too high.
[0042] Please see Figures 1-6 As one implementation of the tank body 1: a level gauge 22 is provided on the side of the tank body 1. The level gauge 22 can monitor the level of ammonia water inside the tank body 1 and located in the vaporization chamber 4, so as to avoid insufficient ammonia water entering and resulting in insufficient utilization of steam heat energy.
[0043] Please see Figures 1-6 As one implementation of the tank body 1: a thermometer 23 is installed on the tank body 1, and the temperature inside the tank body 1 can be monitored by the thermometer 23. Multiple thermometers 23 can be installed at different heights of the tank body 1, so as to flexibly and accurately monitor the temperature in various areas inside the tank body 1.
[0044] In summary:
[0045] In use, this utility model delivers high-temperature steam from the outside through the steam input pipe 6 into the steam delivery chamber 3, and guides the steam through the spiral guide groove 5 in the steam delivery chamber 3, so that the high-temperature steam can flow fully along the spiral guide groove 5 in the steam delivery chamber 3 to heat the partition plate 2.
[0046] Afterwards, the steam flows to the tail end of the spiral guide channel 5, enters the outer spiral heat exchange tube 7, and then enters the inner spiral heat exchange tube 8 after flowing through the outer spiral heat exchange tube 7. Finally, it is discharged from the tank 1 through the steam discharge pipe 9 at the tail end of the inner spiral heat exchange tube 8.
[0047] In this process, ammonia water is transported to the annular conveying pipe 14 through the ammonia water inlet pipe 10, and then transported to the corresponding spray pipe 12 through the cooperation of the annular conveying pipe 14 and the connecting pipe 15. The atomizing nozzle 13 on the spray pipe 12 atomizes and sprays the ammonia water onto the surface of the outer spiral heat exchange pipe 7 and the inner spiral heat exchange pipe 8, thereby exchanging heat with the steam in the outer spiral heat exchange pipe 7 and the inner spiral heat exchange pipe 8 to achieve the heating and vaporization of ammonia water.
[0048] In this invention, the ammonia water does not come into contact with steam or with the outside air, which can improve the cleanliness of the ammonia water during the vaporization process and ensure the concentration after vaporization.
[0049] In this process, by setting the inner spiral heat exchange tube 8 and the outer spiral heat exchange tube 7 together, the flow path of steam in the tank 1 can be extended, the overall flow time in the tank 1 can be extended, and the heat exchange contact area can be increased, thereby improving the heat exchange vaporization effect and efficiency of the sprayed atomized ammonia water and realizing the rapid vaporization of ammonia water.
[0050] At the same time, the amount of ammonia water entering the chamber is controlled to be greater than the maximum vaporization amount of the outer spiral heat exchange tube 7 and the inner spiral heat exchange tube 8. This allows the excess ammonia water to fall to the bottom of the vaporization chamber 4 after being preheated by contact with the outer spiral heat exchange tube 7 and the inner spiral heat exchange tube 8. In this way, the ammonia water accumulated at the bottom of the vaporization chamber 4 can be vaporized through the heat exchange between the high-temperature steam in the spiral guide groove 5 and the partition plate 2.
[0051] In this way, the atomized ammonia water and the liquid ammonia water at the bottom can be heated and vaporized simultaneously, which improves the thermal conversion efficiency and completeness of the steam when heating and vaporizing the ammonia water, improves the vaporization effect and efficiency of the ammonia water, and at the same time improves the thermal conversion efficiency of the steam.
[0052] In the above process, the steam discharged through the steam discharge pipe 9 is transported to the preheating pipe 16 and flows along the annular conveying pipe 14 through the preheating pipe 16 to preheat the ammonia water entering the annular conveying pipe 14. This allows the ammonia water to be preheated before entering the tank 1, reducing the temperature difference of the ammonia water entering the tank 1, maintaining the temperature stability inside the tank 1, reducing the energy required for heat exchange of ammonia water vaporization, improving the effect and efficiency of ammonia water vaporization, and improving the waste heat utilization effect of steam.
[0053] The ammonia gas produced by vaporization is discharged through the ammonia gas discharge pipe 11 at the top;
