Description

Technical Field

[0001] This utility model relates to the field of ammonia treatment technology, and in particular to an automatic exhaust device for an ammonia storage container. Background Technology

[0002] Ammonia storage containers are widely used in chemical, agricultural and refrigeration fields. However, due to the volatility of ammonia and the toxicity, corrosiveness and explosion risk of ammonia gas, pressure and ammonia emissions must be strictly controlled during storage.

[0003] However, existing automatic exhaust systems typically suffer from the following technical drawbacks: 1. Direct release of ammonia gas: The discharged ammonia gas escapes directly into the atmosphere without treatment, polluting the environment and potentially harming human health. 2. Some improved solutions introduce water through the exhaust pipe to absorb ammonia gas, but the gas is released slowly in the form of small bubbles, resulting in low dissolution efficiency and a risk of escape. 3. High cost of sensor control: While intelligent exhaust systems using electronic pressure sensors and solenoid valves can provide precise control, they are complex in structure and have high maintenance costs.

[0019] Example 1

[0020] like Figures 1-6 As shown in the figure, the automatic venting device for an ammonia storage container proposed in this embodiment includes a storage tank 1, a venting pipe 2, a treatment liquid tank 3, an automatic venting device, and an automatic stirring device.

[0021] The exhaust pipe 2 is connected to the upper end of the storage tank 1; the automatic exhaust device includes a piston plate 5, an exhaust pipe 13, a guide plate 14, a sealing plate 15, an elastic telescopic rod mechanism, a push rod 20, a wedge block 18, and a slide table 21.

[0022] Piston plate 5 is movably disposed inside exhaust pipe 2. A first elastic reset assembly is connected between piston plate 5 and exhaust pipe 2. The first elastic reset assembly includes a third guide rod 241 and a third spring 242. Both ends of the third guide rod 241 are connected to the inner wall of exhaust pipe 2. Piston plate 5 is slidably disposed on the third guide rod 241. The third spring 242 is sleeved on the third guide rod 241. It should be added that a sealing ring for sealing the gap between the third guide rod 241 and the piston plate 5 is installed on piston plate 5.

[0023] The vent pipe 13 passes through the piston plate 5, and the sealing plate 15 moves through the vent pipe 13. It should be noted that a sealing gasket is provided on the surface of the sealing plate 15, and a vent hole 151 is opened on the sealing plate 15. A second elastic reset assembly is connected between the sealing plate 15 and the vent pipe 13. The second elastic reset assembly includes a second guide rod 231, a second spring 232, and a second limiting block 233. The upper end of the sealing plate 15 is connected to a second connecting slider 26. The second guide rod 231 is connected to the outer wall of the vent pipe 13. The second connecting slider 26 is slidably disposed on the second guide rod 231. The second limiting block 233 is connected to the outer end of the second guide rod 231. The second spring 232 is sleeved and installed on the second guide rod 231.

[0024] The elastic telescopic mechanism is located on one side of the air outlet pipe 13. The elastic telescopic mechanism includes a sleeve 16, a movable rod 17 and a fourth spring 27. The end of the movable rod 17 is movably located inside the sleeve 16 and is connected to a first connecting slider 25. The fourth spring 27 is located inside the sleeve 16.

[0025] A third elastic reset assembly is connected between the air outlet pipe 13 and the elastic telescopic mechanism. The third elastic reset assembly includes a first guide rod 221, a first limiting block 223, and two first springs 222. The first guide rod 221 movably passes through the sleeve 16. The two ends of the first guide rod 221 are respectively connected to the air outlet pipe 13 and the first limiting block 223. The two first springs 222 are respectively sleeved and installed at the two ends of the first guide rod 221. A ball bearing 19 is installed at the end of the elastic telescopic mechanism. A push rod 20 is vertically connected to the elastic telescopic mechanism.

[0026] The guide plate 14 is connected to the inner wall of the exhaust pipe 2. A section of the guide plate 14 away from the piston plate 5 is bent toward the center of the inner side of the exhaust pipe 2. The slide table 21 is connected to the inner wall of the exhaust pipe 2. The wedge block 18 is set at the end of the slide table 21.

[0027] The treatment liquid tank 3 is installed on the side of the storage tank 1. The top of the treatment liquid tank 3 is connected to a pipe. The automatic stirring device includes a cylinder 4, a rotating tube 7, a stirring plate 8, and multiple rotating plates 9. The cylinder 4 is located at the top of the treatment liquid tank 3. A first connecting pipe 11 is connected between the cylinder 4 and the exhaust pipe 2. The rotating tube 7 is rotatably installed on the treatment liquid tank 3, and its top end passes through the cylinder 4 and is equipped with a rotary joint 10. A second connecting pipe 12 is connected between the rotary joint 10 and the inner cavity of the cylinder 4. Multiple stirring plates 8 are installed at the bottom of the rotating tube 7. It should be noted that a sealing ring for sealing the gap through which the rotating tube passes is installed at the top of the cylinder 4.

[0028] In this embodiment, when the gas pressure inside the storage tank 1 increases due to heating, the gas pushes the piston plate 5 to move. At this time, the end of the vent pipe 13 is sealed, preventing the gas from being discharged normally. As the piston plate 5 gradually moves, it drives the vent pipe 13 and the sleeve 16 to move. In the initial state, the sleeve 16 is located inside the guide plate 14, such as... Figure 3As shown, as the piston plate 5 gradually moves, it can push the sealing plate 15 to move along the guide plate 14. When the sleeve 16 moves to the bent part of the guide plate 14, the first spring 222 on the side adjacent to the exhaust pipe 13 is compressed. When the sleeve 16 separates from the guide plate 14, the sleeve 16 is driven to quickly reset under the elastic force of the first spring 222. During this process, the ball 19 rolls on the inclined surface of the wedge block 18, causing the movable rod 17 to move upward. The movable rod 17 drives the push rod 20 to move, and the push rod 20 pushes the sealing plate 15 to move upward. At this time, the vent hole 151 coincides with the end opening of the exhaust pipe 13, so that the excess gas stored inside the exhaust pipe 2 is concentratedly discharged through the exhaust pipe 13.

[0029] The discharged gas enters the interior of the cylinder 4 through the first connecting pipe 11. The output end of the first connecting pipe 11 is tilted towards the rotating plate 9, causing multiple rotating plates 9 to rotate. The rotation of the rotating plate 9 drives the rotating pipe 7 to rotate, which in turn drives the stirring plate 8 to rotate. The gas inside the cylinder 4 is then discharged into the interior of the rotating pipe 7 through the second connecting pipe 12, and finally discharged to the bottom of the treatment liquid tank 3. The gas mixes with the treatment liquid inside the treatment liquid tank 3. The treatment liquid can be water. Because the stirring plate 8 rotates synchronously during the exhaust process, the rotation of the stirring plate 8 can accelerate the mixing of gas and liquid. During the mixing process, violent turbulence is generated, which greatly increases the gas-liquid contact area, thereby improving the treatment effect of ammonia.

[0030] After the sleeve 16 separates from the guide plate 14, the piston plate 5 is driven to reset under the elastic force of the third spring 242, which pushes the ammonia gas inside the exhaust pipe 2 to be discharged faster. During this process, the sleeve 16 moves along the outer side of the guide plate 14. During this process, the first spring 222 on the side adjacent to the guide plate 14 is in a compressed state. When the sleeve 16 moves to the initial position, the sleeve 16 separates from the guide plate 14, and the ball 19 separates from the slide table 21, so that the sealing plate 15 can automatically reset downwards, thereby re-sealing the opening at the end of the exhaust pipe 13. The sleeve 16 moves to the inner position of the guide plate 14, perfectly realizing the function of automatic reset.

[0031] It should be added that the moving distance of the piston plate 5 is a safe distance. When the piston plate 5 moves to the end position, the air pressure inside the storage tank 1 will not exceed the set limit value. In addition, in order to meet the reset requirements of each spring in this technical solution, the spring constant of each spring is designed in advance according to its actual use requirements.

[0032] In summary, this technical solution reduces the frequency of ammonia emissions by centrally discharging the ammonia gas, preventing damage to the valves caused by frequent opening and closing. The entire exhaust process requires no sensors, achieving complete automation. The pulsed, intermittent exhaust process features high flow rates and velocities, actively driving the stirring plate 8 to rotate and achieve gas-liquid mixing. This disperses the gas into extremely fine bubbles, forcing them to mix violently with water, significantly increasing the gas-liquid contact area and time, thereby improving the ammonia treatment effect.

[0033] Example 2

[0034] like Figure 4 As shown in this embodiment, an automatic exhaust device for an ammonia storage container is proposed. Compared with the first embodiment, in this embodiment, the stirring plate 8 has a hollow structure, and the inner cavity of the stirring plate 8 is connected to the inside of the rotating tube 7. Several fine holes are opened on the stirring plate 8. The setting of the fine holes allows the exhaust gas to mix to various positions of the liquid, increases the exhaust range of the gas and reduces the exhaust speed of the gas, which is conducive to the uniform mixing of gas and liquid.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
