[0001] This utility model relates to the field of ammonia preparation technology, and in particular to a reaction apparatus for preparing ammonia. Background Technology

[0002] Ammonia water, as an important chemical raw material, is widely used in various fields such as agricultural fertilization, industrial desulfurization, pharmaceutical synthesis, and daily cleaning. Its preparation process requires the full mixing and reaction of ammonia gas and water under specific reaction conditions. At the same time, it is necessary to ensure the safety and controllability of the reaction process in order to achieve efficient and stable preparation of ammonia water and provide reliable raw material support for subsequent applications in various fields. Therefore, the development of a reaction device for preparing ammonia water with a reasonable structure and convenient operation has important practical application significance.

[0003] In existing technologies, it is impossible to flexibly control the gas flow rate based on concentration changes during the reaction process, and it is difficult to obtain concentration data in the reaction system in real time. This can easily lead to deviations in ammonia concentration, failing to meet the precise requirements for ammonia concentration in different scenarios and reducing the quality and production efficiency of ammonia. Utility Model Content

[0004] In view of the above-mentioned problems that existing methods cannot flexibly control the gas flow rate according to the concentration changes during the reaction process, and it is difficult to obtain the concentration data in the reaction system in real time, which easily causes the ammonia concentration deviation and cannot meet the precise requirements of ammonia concentration in different scenarios, thus reducing the quality and production efficiency of ammonia, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a reaction device for preparing ammonia water, comprising a reaction structure, a control panel, an air inlet structure, and a mixing component. The reaction structure includes a tank. The air inlet structure includes an air inlet pipe, a first rotating shaft, a first motor, an ammonia concentration analyzer, and an annular pipe. A connector is fixedly installed at the end of the air inlet pipe. Rotating seats are fixedly installed on the upper and lower outer walls of the air inlet pipe, respectively. The first rotating shaft is rotatably mounted on the air inlet pipe via the rotating seats. An adjusting plate is fixedly installed on the first rotating shaft. A sealing ring is provided on the outer wall of the adjusting plate. The motor shaft of the first motor is fixedly connected to the top end of the first rotating shaft. The ammonia concentration analyzer is inserted into the tank. Several atomizing nozzles are provided on the annular pipe. A water inlet pipe is fixedly connected to one end of the annular pipe.

[0006] As a preferred embodiment of the reaction apparatus for preparing ammonia water according to the present invention, the reaction structure includes a top cover, a support column fixedly installed at the bottom of the tank, a drain valve installed at the bottom of the tank through a drain pipe, the top cover being bolted to the top of the tank, and the control panel being installed on the outer wall of the tank.

[0007] In a preferred embodiment of the reaction apparatus for preparing ammonia water according to the present invention, the air inlet pipe is fixedly installed on the outer wall of the tank and communicates with the interior of the tank; the rotating seats are respectively fixedly installed on the upper and lower outer walls of the air inlet pipe; and the first rotating shaft is rotatably disposed between the rotating seats.

[0008] In a preferred embodiment of the reaction apparatus for preparing ammonia water according to the present invention, the first motor is fixedly mounted on the top of the air inlet pipe via a frame, the annular pipe is fixedly mounted on the inner side wall of the top cover, and the first motor, the ammonia concentration analyzer and the control panel are electrically connected.

[0009] In a preferred embodiment of the reaction apparatus for preparing ammonia water according to the present invention, the mixing component includes a second rotating shaft, a second motor and a circulating pump. The second rotating shaft is rotatably installed in the top wall of the top cover, the second motor is fixedly installed on the top of the top cover, and the motor shaft of the second motor is fixedly connected to the second rotating shaft. A distribution plate is fixedly provided on the second rotating shaft.

[0010] In a preferred embodiment of the reaction apparatus for preparing ammonia water according to the present invention, the circulating pump is fixedly installed on the outer wall of the tank by a support plate, the inlet end of the circulating pump is connected to the outlet pipe through the inlet pipe and the outlet end of the circulating pump is connected to the top of the side wall of the tank through the outlet pipe, and the second motor, the circulating pump and the control panel are electrically connected.

[0011] The beneficial effects of this utility model are: 1. Through the designed air intake structure and atomizing nozzle, water can be efficiently atomized and fully contacted with ammonia gas, improving mixing efficiency. The rotation of the regulating plate driven by the first motor can adjust the opening size of the air intake pipe in real time, thereby flexibly controlling the flow rate and concentration of ammonia gas. With the real-time monitoring function of the ammonia gas concentration analyzer, the control panel can dynamically adjust according to the ammonia gas concentration data in the tank, ensuring that the mixing ratio of ammonia gas and water is always at the optimal state, improving the operational accuracy in the production process, and effectively avoiding the problem of excessive or insufficient ammonia gas, thus ensuring the quality of ammonia water and production efficiency. 2. Through the set mixing components, the second motor is started by controlling the control panel, which drives the second rotating shaft and the distribution plate to rotate slowly. This allows ammonia gas and atomized water to be in contact and mixed on the distribution plate for a long time, effectively extending the gas-liquid contact time and improving the initial mixing efficiency. The circulation pump draws liquid from the bottom of the tank and delivers it to the top of the side wall of the tank to form a circulation, allowing the unsaturated ammonia water to come into contact with ammonia gas again, further compensating for the problem of uneven local mixing and improving the overall mixing uniformity.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0015] Refer to attached figure Figure 1 - Appendix Figure 4 This is the first embodiment of the present invention, which provides a reaction device for preparing ammonia water, including a reaction structure 1, a control panel 2, an air inlet structure 3, and a mixing component 4. The control panel 2, the air inlet structure 3, and the mixing component 4 are respectively installed on the reaction structure 1. The reaction structure 1 includes a tank body 11 and a top cover 14. A support column 12 is fixedly installed at the bottom of the tank body 11 to support the tank body 11. A drain pipe is provided at the bottom of the tank body 11, and a drain valve 13 is provided on the drain pipe. The top cover 14 is installed on the top of the tank body 11 by bolts. The control panel 2 is installed on the outer wall of the tank body 11.

[0016] The air intake structure 3 includes an air intake pipe 301, a first motor 308, an ammonia concentration analyzer 309, and an annular pipe 310. The air intake pipe 301 is fixedly installed on the outer wall of the tank 11 and communicates with the interior of the tank 11. A connector 302 is fixedly installed at the end of the air intake pipe 301. Rotating seats 304 are fixedly installed on the upper and lower outer walls of the air intake pipe 301, respectively. A first rotating shaft 303 is rotatably arranged between the rotating seats 304. An adjusting plate 305 is fixedly installed on the first rotating shaft 303. A sealing ring 306 is provided on the outer wall of the adjusting plate 305. The sealing ring 306 contacts the inner wall of the air intake pipe 301, which can control the air intake pipe 301. The first motor 308 is fixedly installed at the top of the air inlet pipe 301 via the frame 307, and the motor shaft of the first motor 308 is fixedly connected to the top of the first rotating shaft 303. The ammonia concentration analyzer 309 is inserted into the tank 11 to monitor the ammonia concentration inside the tank 11. The annular pipe 310 is fixedly installed on the inner side wall of the top cover 14. Several atomizing nozzles 312 are installed on the annular pipe 310. One end of the annular pipe 310 is fixedly connected to the water inlet pipe 311, which passes through the top cover 14 and extends to the outside of the top cover 14. The first motor 308, the ammonia concentration analyzer 309 and the control panel 2 are electrically connected.

[0017] During use, firstly, connect the water inlet pipe 311 to an external water pump and water source. Water is delivered to the annular pipe 310, then atomized by the atomizing nozzle 312 and sprayed into the tank 11. External ammonia gas enters the air inlet pipe 301 through the connector 302. The control panel 2 controls the start of the first motor 308. The motor shaft of the first motor 308 drives the first rotating shaft 303 to rotate in the rotating seat 304, which in turn drives the adjusting plate 305 to rotate, opening the air inlet pipe 301. Ammonia gas enters the tank 11 and mixes with the atomized water. The ammonia concentration analyzer 309 monitors the ammonia concentration in the tank 11 in real time and transmits the data to the control panel 2. The operator can adjust the first motor 308 through the control panel 2 according to the concentration data, and then adjust the rotation angle of the adjusting plate 305 to control the ammonia gas intake. After preparation is completed, close all components, open the drain valve 13, and discharge the ammonia water through the drain pipe. Example 2

[0018] Refer to attached figure Figure 5 and attached Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: The mixing assembly 4 includes a second rotating shaft 41, a second motor 42, and a circulation pump 44. The second rotating shaft 41 is rotatably mounted in the top wall of the top cover 14 and extends into the interior of the tank body 11. The second motor 42 is fixedly mounted on the top of the top cover 14, and the motor shaft of the second motor 42 is fixedly connected to the second rotating shaft 41. A distribution plate 43 is fixedly mounted on the second rotating shaft 41. The circulation pump 44 is fixedly mounted on the outer wall of the tank body 11 by a support plate. The inlet end of the circulation pump 44 is connected to the outlet pipe through the inlet pipe 45 and the outlet end of the circulation pump 44 is connected to the top of the side wall of the tank body 11 through the outlet pipe 46. The second motor 42 and the circulation pump 44 are electrically connected to the control panel 2.

[0019] During use, the control panel 2 controls the start of the second motor 42 and the circulation pump 44. The second motor 42 drives the second rotating shaft 41 to rotate slowly, thereby driving the distribution plate 43 to rotate. Ammonia and atomized water droplets fall on the distribution plate 43 for a long time to mix, thereby improving the mixing efficiency. When the mixed liquid condenses into larger water droplets, the water droplets fall because of the rotation of the distribution plate 43. The circulation pump 44 draws the liquid from the bottom of the tank 11 through the liquid inlet pipe 45, and then delivers it to the top of the side wall of the tank 11 through the liquid outlet pipe 46 for spraying, forming a circulation, so that the unsaturated ammonia water formed is further mixed with ammonia, improving the mixing uniformity.
