For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0034] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The existing synthetic ammonia waste heat boiler device has no leak detection device, and is only equipped with a safety valve 35 to prevent overpressure. When the leakage is extremely large, the safety valve 35 can be tripped to detect it, but when the leakage is small, it is generally not found in the large steam system. With long-term leakage, combustible gas accumulates at the terminal of the steam system, which may cause explosion safety hazards during hot work. Based on this, the present application provides a synthetic ammonia waste heat boiler leak detection device, including a synthetic boiler 1 for synthesizing a target object, a detection component 1 2 and a detection component 2 3 arranged on the boiler, which are used to detect the leakage of the target object;

[0036] The detection component 1 2 includes a pipe 21, one end of which is combined with the sampling port of the synthesis boiler 1, and one or more color indicating components 22 are arranged at the pipe body of the pipe 21 for detecting steam in which the target object is dissolved;

[0037] A cooling component 23 is provided at the other end of the pipe 21, and a condenser 24 is provided at the bottom of the cooling component 23 for cooling the steam;

[0038] An absorption box 25 is provided at the bottom of the condenser 24 to cooperate with the condenser 24 to absorb the liquefied steam.

[0039] First, when the synthesis boiler 1 is in operation, the detection component 2 is connected to the sampling port of the synthesis boiler 1 through the pipeline 21 to ensure that the target substance in the steam can be sampled and monitored in time. The design of the pipeline 21 allows the steam to flow smoothly, and a color indicating component 22 is set on the pipe body. These components can detect the target substance in a targeted manner. Once the target substance leaks into the steam, the color indicating component 22 will change color, reminding the operator that there may be a leak.

[0040] Secondly, the other end of the pipe 21 is provided with a cooling component 23, which is used to cool the steam. Inside the cooling component 23, a condenser 24 is provided, which can effectively reduce the temperature of the steam and promote its liquefaction. This process is to better handle the leaked steam and avoid it from causing pollution to the environment or safety hazards.

[0041] Finally, an absorption box 25 is also provided at the bottom of the condensing pipe 24 to absorb the liquefied steam. In this way, even if a leak occurs, the liquefied steam will not have an impact on the environment because it will be effectively absorbed and processed to ensure the safety of the environment and personnel.

[0042] By comprehensively utilizing the color indicating component 22, the cooling component 23 and the absorption box 25, it is possible to achieve real-time monitoring and treatment of target substance leakage in the synthetic ammonia waste heat boiler, thereby effectively preventing the occurrence of safety incidents. At the same time, through the treatment of liquefied steam, the purpose of environmental protection is also achieved, the impact on the environment is reduced, and the safety and sustainability of the workplace are improved.

[0043] The color indicating component 22 needs to be highly selective and can accurately detect ammonia to avoid false alarms or missed alarms. Secondly, the response speed of the color indicating component 22 is also crucial. It needs to be able to quickly change color when ammonia leaks to provide a timely warning signal. In addition, the color change of the color indicating component 22 should be obvious and eye-catching, and can be easily observed from a distance or in a dimly lit environment to ensure that the operator can detect the leak in time.

[0044] In terms of specific design, the color-indicating component 22 can use special chemical reagents or materials to produce obvious color changes after a specific chemical reaction with ammonia. For example, a pH indicator or a dye containing an ammonia-sensitive group can be used. When ammonia comes into contact with these reagents, it will cause a significant change in the color of the reagent, thereby realizing the detection of ammonia leakage. In addition, an optical element or a fluorescent dye can be introduced into the color-indicating component 22 to generate a specific fluorescent signal when it is irradiated with excitation light, further improving the sensitivity and accuracy of the detection.

[0045] See also Figure 1 , Figure 2 , Figure 3 The color indicating component 22 includes a accommodating cavity 221, a dripping port 222 is opened on the top of the accommodating cavity 221 for dripping the color developing reagent, and a card block 224 arranged in a circular array is arranged on the inner side of the accommodating cavity 221, and a supporting plate 226 is arranged between the multiple card blocks 224 for loading the test paper.

[0046] One or more through holes are provided on the top of the supporting plate 226 for contact between steam and the test paper. A reagent contact area 223 is provided above the supporting plate 226 at the test paper for contact between the test paper and the reagent.

[0047] A thread groove 225 is provided at the bottom of the supporting plate 226 on the inner side of the accommodating cavity 221 , and the thread groove 225 is threadably connected to the air outlet provided on the pipe 21 .

[0048] The color indicating component 22 includes a containing cavity 221, and a dripping port 222 is provided on the top thereof for dripping a color developing reagent into the containing cavity 221. Card blocks 224 arranged in a circular array are arranged inside the containing cavity 221, and a supporting plate 226 is provided between these card blocks 224 for supporting and loading the test paper. One or more through holes are provided on the top of the supporting plate 226 so that the steam can fully contact the test paper, and a reagent contact area 223 is provided above the supporting plate 226 to ensure that the test paper can fully contact the reagent. A threaded groove 225 is provided on the inner bottom of the containing cavity 221, which is threadedly connected to the air outlet on the pipe 21 to ensure that the color indicating component 22 is tightly connected to the pipe 21 and the steam passes smoothly.

[0049] In actual application, the operator drips the color developing reagent into the containing cavity 221 through the drip port 222 to fully soak the test paper. The steam enters the color indicating component 22 through the pipe 21, contacts the test paper and is adsorbed by the test paper, and the ammonia in it reacts with the reagent. The block 224 and the support plate 226 play a supporting and positioning role, ensuring that the test paper is in the correct position and fully exposed to the steam, which can effectively contact the test paper with the reagent and maintain a stable contact state. Through the close connection with the pipe 21, the color indicating component 22 can accurately monitor the ammonia in the steam and promptly detect possible leaks;

[0050] At the same time, the structural design of the color indicating component 22 makes it easy to install and maintain, improving the reliability and use efficiency of the equipment. The application of this color indicating component 22 can effectively ensure the safe operation of the synthetic ammonia waste heat boiler, reduce the harm caused by ammonia leakage to the environment and personnel, and further improve the safety and sustainability of the workplace.

[0051] See also Figure 1 , Figure 4 The absorption box 25 includes an outer shell 253 , one or more absorption plates 252 are arranged inside the outer shell 253 , a spacing area 251 is maintained between every two absorption plates 252 , and the inner side of the absorption plate 252 is filled with an absorption medium 254 .

[0052] The outer shell 253 of the absorption box 25 is usually made of corrosion-resistant materials (such as plastic), and one or more absorption plates 252 are arranged inside, and a spacing area 251 is maintained between every two absorption plates 252. The inner sides of these absorption plates 252 are filled with a specific absorption medium 254, such as activated carbon or chemical absorbent (such as acetic acid, etc.), which can quickly absorb ammonia molecules and other harmful gases.

[0053] When the synthetic ammonia waste heat boiler discharges ammonia, the ammonia enters the absorption box 25 through the discharge port. The absorption medium 254 is filled on the inner side of the absorption plate 252. Its high surface area and special chemical properties enable it to quickly adsorb ammonia molecules. The design of the spacing area 251 ensures that the gas can flow evenly through the absorption medium 254, thereby improving the adsorption efficiency and adsorption capacity.

[0054] The absorption box 25 can effectively capture and treat harmful gases such as ammonia, reducing the impact on the environment and personnel health. Through the filling of the absorption medium 254 and the reasonable structural design, the absorption box 25 can achieve efficient gas treatment effect in a shorter time. In addition, the absorption box 25 is easy to install and maintain, and has high reliability and stability, thereby improving the overall performance and safety of the waste heat boiler system. The application of this absorption box 25 helps to reduce ammonia emissions and protect the environment.

[0057] A safety valve 35 is disposed above the collecting pipe 34 . A through hole is formed on one side of the safety valve 35 and is sealedly connected to a sealing block 36 .

[0058] The branch pipe 31 is connected to one end of the pipeline 21 and is designed to guide the hot gas to the detection system. The other end of the branch pipe 31 is connected to the refrigeration assembly 32, which quickly cools the hot gas to the temperature range required for detection through the internal cooling device. The other end of the refrigeration assembly 32 is connected to the inclined conduit 33, which guides the cooled gas to flow downstream.

[0059] One end of the inclined conduit 33 is provided with a threaded joint 37, a sealing block 36 is installed at the threaded joint 37, and a collecting tube 34 is provided on one side of the sealing block 36. The design of the sealing block 36 ensures that the gas sample will not leak during the transmission process, thereby ensuring the accuracy of the detection. The collecting tube 34 is located below the sealing block 36 and is used to collect the cooled gas sample.

[0060] A safety valve 35 is installed above the collecting pipe 34. A through hole is provided on one side of the safety valve 35, and the through hole is sealed and connected to a sealing block 36 to ensure the tightness of the gas sample. The function of the safety valve 35 is to automatically start when the system pressure exceeds the set value, release the overpressure gas, and thus protect the safe operation of the entire system.

[0061] Through the cooling effect of the refrigeration assembly 32, the hot gas can be quickly cooled to the temperature range required for detection, ensuring the accuracy of the detection. The design of the inclined conduit 33 and the sealing block 36 ensures the stable collection and transmission of the gas sample, avoiding the interference of gas leakage on the detection results. At the same time, the setting of the safety valve 35 improves the safety of the system and avoids the potential danger caused by excessive pressure.

[0062] See also Figure 7 The refrigeration assembly 32 includes at least two combined shells 321. The inner sides of the two combined shells 321 are each provided with a semiconductor refrigeration plate 324 for fitting with the inclined conduit 33 to cool the steam.

Two groups of positioning holes 322 are also provided on the inner side of the combined shell 321 , and the two groups of positioning holes 322 are connected by fasteners.

[0064] Each combined shell 321 is provided with a semiconductor refrigeration plate 324 on the inside. These plates realize refrigeration through current control, so that they are in contact with the inclined conduit 33 to cool the steam. Seals 323 are provided at both ends of the combined shell 321. These seals 323 are used to clamp and fix the inclined conduit 33 to ensure that no gas leakage occurs during the refrigeration process. In addition, two groups of positioning holes 322 are provided on the inside of the combined shell 321. These holes are connected by fasteners to ensure the stability and sealing of the combined shell 321.

[0065] The semiconductor refrigeration plate 324 of the refrigeration assembly 32 has a refrigeration principle of making one side of the semiconductor material cold and the other side hot through current control, thereby achieving a refrigeration effect on the gas.
