Description

TECHNICAL FIELD

[0001] The utility model relates to waste gas recovery technical field, concretely is a multistage adsorption formula ammonia gas recovery tank. BACKGROUND

[0002] The ammonia gas recovery tank is a device for collecting and recovering ammonia gas, which is usually used in industrial production. The main purpose of ammonia gas recovery is to reduce ammonia gas emissions, avoid pollution to the environment, and improve the utilization efficiency of ammonia gas. The existing ammonia gas collecting device (publication number: CN211487173U) has at least the following defects in use:

[0003] 1. Multistage adsorption can gradually reduce the concentration of ammonia gas by stages, and each stage of adsorbent can work at a higher concentration, thereby improving the overall adsorption efficiency. If only single-stage adsorption is used, it may not be able to effectively remove high-concentration ammonia gas, resulting in low recovery efficiency. Therefore, a multistage adsorption ammonia gas recovery tank is needed.

[0004] 2. If ammonia gas enters the adsorption equipment directly without condensation and liquefaction treatment, the adsorption equipment needs to handle high-concentration ammonia gas, which will cause the adsorbent to saturate quickly, resulting in reduced adsorption efficiency. High concentration of ammonia gas may cause the adsorption capacity of the adsorbent to reach saturation in a short time, reducing the service life of the adsorbent, and requiring frequent replacement or regeneration of the adsorbent. Therefore, a condensable ammonia gas recovery tank is needed.

[0005] 3. Secondary recovery is usually used to further capture and recover ammonia gas, which means it can effectively utilize ammonia gas that may not be fully recovered by the primary recovery system. Without secondary recovery, ammonia gas remaining in the primary recovery process may be wasted or discharged into the environment, thereby reducing the overall recovery efficiency. Therefore, an ammonia gas recovery tank with secondary recovery is needed. SUMMARY

[0006] The main purpose of the utility model is to provide a multistage adsorption ammonia gas recovery tank, which can effectively solve the problems in the background art.

[0007] To achieve the above purpose, the technical scheme adopted by the utility model is:

[0008] A multi-stage adsorption ammonia recovery tank, comprising a main recovery tank, a primary recovery tank and a condensing tank, one side of the main recovery tank is provided with the primary recovery tank, a gas inlet pipeline and a gas inlet motor are installed on the primary recovery tank, the other side of the main recovery tank is provided with the condensing tank, a circulating motor is installed at the top of the condensing tank, a circulating pipeline is installed on the circulating motor, the other end of the circulating pipeline is installed in the main recovery tank, a gas outlet pipeline is arranged at the bottom of the main recovery tank, a main motor is arranged at the top of the main recovery tank, a plurality of supporting legs are arranged at the bottom of the main recovery tank, and a crawling ladder is arranged on the side of the main recovery tank.

[0009] Preferably, the main recovery tank, the primary recovery tank and the condensing tank are connected through pipelines.

[0010] Preferably, sealing covers are arranged on the main recovery tank, the primary recovery tank and the condensing tank.

[0011] Preferably, a plurality of observation windows are arranged on the side of the main recovery tank.

[0012] Preferably, the primary recovery tank and the condensing tank are connected to the main recovery tank through supports.

[0013] Preferably, a valve is arranged on the gas outlet pipeline.

[0014] Compared with the prior art, the multi-stage adsorption ammonia recovery tank has the following beneficial effects:

[0015] 1. By installing the primary recovery tank, the ammonia recovery efficiency is significantly improved, and the service life of the adsorbent is also prolonged. Gradually reducing the ammonia concentration enables each adsorption tower to work under optimal conditions, avoiding the problem of premature saturation of the adsorbent due to high-concentration gas, thereby reducing the replacement frequency of the adsorbent and maintenance costs.

[0016] 2. By installing the condensing tank, ammonia can be cooled and liquefied, reducing the concentration of gaseous ammonia and the concentration of ammonia entering the adsorption equipment.

[0024] EMBODIMENT

[0025] Please refer to Figs. 1-2 The utility model provides technical schemes:

[0026] A multi-stage adsorption type ammonia gas recovery tank, comprising a main recovery tank 1, a primary recovery tank 2 and a condensing tank 3, one side of the main recovery tank 1 is provided with the primary recovery tank 2, the primary recovery tank 2 is provided with an intake pipeline 4 and an intake motor 5, the other side of the main recovery tank 1 is provided with the condensing tank 3, the condensing tank 3 is provided with a circulating motor 9 at the top, the circulating motor 9 is provided with a circulating pipeline 7, one end of the circulating pipeline 7 is installed in the main recovery tank 1, the main recovery tank 1 is provided with an exhaust pipeline 8 at the bottom, the main recovery tank 1 is provided with a main motor 6 at the top, the main recovery tank 1 is provided with a plurality of support legs 10 at the bottom, and the main recovery tank 1 is provided with a ladder 11 on the side.

[0027] Specifically, the main recovery tank 1 is connected with the primary recovery tank 2 and the condensing tank 3 through pipelines.

[0028] Specifically, the main recovery tank 1, the primary recovery tank 2 and the condensing tank 3 are provided with sealing covers.

[0029] Specifically, the main recovery tank 1 is provided with a plurality of observation windows 12 on the side.

[0030] Specifically, the primary recovery tank 2 and the condensing tank 3 are connected to the main recovery tank 1 through a support 13.

[0031] Specifically, a valve is installed on the air outlet pipeline 8.

[0032] In the embodiment, the main recovery tank 1 is provided with the primary recovery tank 2 on one side, and the primary recovery tank 2 is provided with the air inlet pipeline 4 and the air inlet motor 5. The core idea of the multi-stage adsorption design is to process the ammonia gas in stages according to the concentration. Each stage of the adsorption tower processes ammonia gas with different concentrations. In the system, the primary recovery tank 2 processes the part with higher ammonia gas concentration, and the main recovery tank 1 processes the remaining part with lower ammonia gas concentration.

[0033] In the primary recovery tank 2, the adsorbent can work at a higher concentration due to the higher ammonia gas concentration, and the adsorption efficiency is higher. At this time, the ammonia gas can be quickly adsorbed by the adsorbent, reducing the transmission and diffusion of high-concentration ammonia gas in the system. With the multi-stage adsorption of ammonia gas, the concentration of ammonia gas gradually decreases. The ammonia gas entering the main recovery tank 1 has a lower concentration, so the adsorbent no longer needs to process high-concentration ammonia gas, but slowly adsorbs at a low concentration, which can ensure the use efficiency of the adsorbent. Each stage of the adsorption tower works in the appropriate concentration range. High-concentration ammonia gas is quickly adsorbed by the adsorbent of the primary recovery tank 2, while low-concentration ammonia gas is processed by the adsorbent of the main recovery tank 1. In this way, the system can maximize the recovery efficiency at each stage, avoiding the accumulation of excessive ammonia gas in a single adsorption tower, and ensuring the efficient recovery of ammonia gas.

[0034] Another important advantage of multi-stage adsorption is the gradual reduction of ammonia gas concentration. Each stage of the adsorption tower processes gas with different concentrations, gradually removing ammonia gas from the exhaust gas. Through this staged processing method, the adsorbent can work under suitable conditions, avoiding the situation that low-concentration ammonia gas is not effectively adsorbed. Each stage of the adsorption tower tries to adsorb ammonia gas in the most optimized state, so the total recovery rate of the entire recovery process is significantly improved. The gradual reduction of ammonia gas concentration not only improves the capture efficiency of ammonia gas, but also gradually removes ammonia gas from the exhaust gas, reducing the limitations of single-stage adsorption that cannot handle high-concentration ammonia gas.

[0035] In a single-stage adsorption system, the adsorbent's capacity to adsorb ammonia gas can quickly reach saturation when the ammonia gas concentration is too high. This means that the adsorbent quickly loses its effectiveness and needs to be replaced or regenerated frequently. In a multi-stage adsorption system, the ammonia gas concentration is gradually reduced in stages. This significantly slows down the saturation rate of the adsorbent. In the primary recovery tank 2, although the ammonia gas concentration is high, the adsorbent does not immediately reach its maximum load because only this stage needs to handle high concentrations of ammonia gas. Subsequently, when low-concentration ammonia gas passes through the adsorbent of the main recovery tank 1, the adsorbent's load is reduced, and the adsorbent is not quickly saturated. This gradual reduction in ammonia gas concentration ensures that the adsorbent in each adsorption tower works at the most appropriate concentration and is not prematurely saturated by the sudden influx of high-concentration ammonia gas. This reduces the workload of the adsorbent, thereby reducing the frequency of replacing or regenerating the adsorbent.

[0036] The service life of the adsorbent is closely related to whether it is prematurely saturated and the size of its workload. In a multi-stage adsorption system, the adsorbent's load is effectively distributed, avoiding the rapid saturation of the adsorbent under high-concentration gas. The adsorbent in each adsorption tower works under different concentrations of gas, so that the adsorbent does not have a high load under high-concentration gas, extending the service life of the adsorbent. When low-concentration gas flows through the main recovery tank 1, the adsorbent's load is reduced, the adsorption efficiency is improved, and the adsorbent is not quickly consumed by overwork.

[0037] In a multi-stage adsorption system, because the adsorbent is used more evenly in each stage, the frequency of replacing the adsorbent is lower, reducing the cost of replacing the adsorbent. Long-term efficient operation reduces the overall operating cost of the adsorption system. In addition to reducing the frequency of replacing the adsorbent, it also reduces maintenance costs and equipment downtime due to excessive consumption of the adsorbent, thereby improving overall economic efficiency.

[0038] Through the multi-stage adsorption system, the recovery efficiency of ammonia gas is significantly improved, and the service life of the adsorbent is also extended. Gradually reducing the ammonia gas concentration allows each adsorption tower to work under optimal conditions, avoiding the problem of premature saturation of the adsorbent due to high-concentration gas, thereby reducing the frequency of replacing the adsorbent and maintenance costs. The entire system operates more stably, economically, and environmentally friendly.

[0039] In this embodiment, the main recovery tank 1 is provided with a condensation tank 3 on the other side. The condensation tank 3 liquefies the ammonia gas by cooling it, reducing the concentration of gaseous ammonia, and reducing the concentration of ammonia entering the adsorption equipment. This helps to reduce the burden of high-concentration ammonia on the adsorbent, allowing the adsorbent to work efficiently for a longer period of time. In contrast, if the gas without condensation directly enters the adsorption tower, the ammonia concentration is too high, which can easily cause the adsorbent to saturate and significantly reduce the adsorption efficiency. The condensation tank 3 helps to convert part of the ammonia from gas to liquid, reducing the volume and concentration of the gas before it enters the adsorption tower, thereby improving the efficiency of the subsequent adsorption process.

[0040] The concentration of condensed ammonia is low, avoiding the direct entry of high-concentration ammonia into the adsorption tower, which can quickly saturate the adsorbent. In a multi-stage adsorption system, the adsorbent in the primary recovery tank 2 and the main recovery tank 1 can function in a lower-concentration ammonia environment, reducing the risk of excessive saturation of the adsorbent. This can significantly extend the service life of the adsorbent and reduce the frequency of replacing or regenerating the adsorbent. Through condensation and liquefaction, the condensation tank 3 recovers part of the ammonia from gaseous ammonia, reducing the workload of the adsorption equipment and slowing down the consumption rate of the adsorbent, thereby extending its service life.

[0041] Thanks to the presence of the condensation tank 3, the ammonia concentration is effectively controlled, and the adsorbent gradually adsorbs ammonia at a lower concentration, which is less likely to saturate quickly. This can greatly reduce the frequency of replacing the adsorbent and the need for regeneration. Reducing the consumption of adsorbent also avoids frequent system downtime and maintenance costs. The condensation process removes part of the ammonia while avoiding the entry of large amounts of ammonia into the adsorption tower, reducing the consumption of adsorbent and making the entire system run more cost-effectively.

[0042] The condensation tank 3 liquefies the ammonia gas, reducing the gas load entering the adsorption system and avoiding the problem of overloading when ammonia suddenly enters the adsorption tower. This control allows the adsorption tower to maintain a more stable working state, improving the stability and reliability of the system. As the working conditions of the adsorbent are optimized, the overall operating life of the equipment is also extended. The use of the condensation tank 3 reduces gas load and reduces the need for excessive wear and frequent maintenance of the equipment, improving the overall performance of the equipment.

[0043] Through condensation, the volume of ammonia is significantly compressed. Smaller volume helps to reduce the flow resistance of gas in the adsorption system, thereby reducing the energy consumption of the system. This design can effectively reduce energy consumption and improve the energy utilization efficiency of the system. When liquefying ammonia, the condensation tank 3 also reduces the heat load in the adsorption tower. Reducing heat energy consumption helps to optimize the energy of the system.

[0044] The condensation tank 3 can recover more ammonia gas, reducing the amount of ammonia gas not recovered in the exhaust gas. This recovery method helps reduce environmental impact, meets environmental standards, and reduces the amount of ammonia gas emitted into the atmosphere. Ammonia emissions can cause air pollution and even acid rain. By reducing ammonia emissions through condensation, it helps reduce the negative impact on the environment and meets increasingly stringent environmental regulations.

[0045] With the condensation tank 3, the concentration of ammonia gas entering the adsorption tower can be precisely controlled, allowing each adsorption stage to adjust operating parameters based on the actual concentration of the gas, thereby improving recovery efficiency and system flexibility. In a multi-stage adsorption process, the design of the condensation tank 3 and the main recovery tank 1 allows the system to adjust the processing intensity of each stage according to different concentrations of ammonia gas, ensuring that each stage operates in the best working state.

[0046] By introducing the condensation tank 3, the ammonia recovery system not only reduces gas concentration and volume, improves adsorption efficiency, and extends the service life of the adsorbent, but also significantly reduces energy consumption and operating costs. The condensation tank 3 shares the burden of the adsorption tower, optimizing the entire recovery process, thereby achieving more efficient, economical and environmentally friendly ammonia recovery.

[0047] In this embodiment, the condensation tank 3 is installed at the top of the circulating motor 9, and the circulating pipe 7 is installed on the circulating motor 9, with the other end of the circulating pipe 7 installed inside the main recovery tank 1.

[0048] In the initial recovery process, although most of the ammonia gas has been captured, there will still be some ammonia gas that has not been completely adsorbed or condensed. If there is no secondary recovery, these residual ammonia gases may be wasted or directly discharged into the environment, causing resource loss and pollution. By introducing a secondary recovery system, these residual ammonia gases can be effectively captured, further improving overall recovery efficiency. Secondary recovery captures ammonia gas that was not captured during the initial recovery process, preventing their emission. This not only improves resource recovery rate, but also helps reduce ammonia pollution to the environment.

[0049] Secondary recovery can recover ammonia gas that was not completely recovered in the initial recovery, ensuring that all ammonia gas can be effectively utilized. This effectively improves the utilization rate of ammonia gas as an important resource, especially in industries such as fertilizer production, reducing raw material waste. By secondary recovery, more ammonia gas is recovered into the system, reducing dependence on external ammonia raw materials. This helps reduce production costs and improve overall economic efficiency.

[0050] As secondary recovery can improve the recovery rate of ammonia gas, it reduces the ammonia content in the exhaust gas, which can reduce the demand for new adsorbent for a longer period of time. This can reduce the frequency of replacement of adsorbent, maintenance costs and regeneration processing costs, thereby reducing the operating costs of the entire system. By capturing the incompletely recovered ammonia gas and adsorbing or condensing it again, the energy efficiency of the recovery system can be optimized. The design of the circulating motor 9 and the circulating pipeline 7 further improves the efficiency of gas treatment and reduces the energy consumption required for single recovery.

[0051] The secondary recovery system can ensure that ammonia gas is almost completely recovered, which means that the adsorbent in the adsorption tower will not be prematurely saturated due to residual ammonia gas that has not been captured. In this way, the service life of the adsorbent will be extended, reducing the cost of frequent replacement of adsorbent. As more ammonia gas is recovered rather than wasted, the burden on equipment such as adsorption towers, condensers 3, etc. is reduced, which helps to extend the service life of the equipment and improve the long-term stability of the system.

[0052] Secondary recovery can capture residual ammonia gas after primary recovery, avoiding the emission of ammonia gas. This not only reduces air pollution caused by ammonia gas, but also helps to avoid environmental problems such as acid rain, in line with increasingly stringent environmental regulations. Through the secondary recovery system, the recovery rate can be ensured to be close to 100%, greatly reducing the emission of harmful gases. This can ensure that industrial enterprises that need to strictly comply with environmental regulations meet environmental standards and reduce legal and environmental pressures.

[0053] The introduction of the secondary recovery system makes the overall recovery process more flexible. Through the adjustment of the circulating motor 9 and the circulating pipeline 7, the intensity of the recovery process can be dynamically adjusted as needed to ensure that ammonia gas can be recovered under suitable conditions. In the case of varying ammonia concentrations, the secondary recovery system can effectively adapt to the recovery needs of exhaust gas with different concentrations, and through flexible airflow adjustment, the overall recovery efficiency is improved.

[0054] During the primary recovery process, the incompletely recovered ammonia gas may have a higher concentration. Without secondary recovery, these high-concentration gases would directly enter the environment or cause excessive load on the adsorption tower, affecting the stability of the adsorption system. Through secondary recovery, the concentration of ammonia gas can be reduced, making the subsequent system processing load balanced and ensuring stable operation of the equipment. The secondary recovery system captures more ammonia gas, avoiding excessive load on the equipment due to residual ammonia gas, thereby improving the durability and long-term stability of the entire recovery system.

[0055] The secondary recovery system is usually equipped with an intelligent control system that can monitor ammonia concentration and recovery efficiency in real time and dynamically adjust the secondary recovery intensity. This makes the entire recovery process more accurate and avoids energy waste caused by improper operation or system abnormalities. Through monitoring and data analysis, the ammonia recovery process can be optimized to ensure that each link achieves the best results and improves the overall system efficiency.

[0056] By introducing a secondary recovery system, the ammonia recovery tank can significantly improve overall recovery efficiency, maximize resource utilization, and reduce raw material procurement costs and operating expenses. Secondary recovery not only optimizes energy and adsorbent use, reducing ammonia emissions in waste gas, but also reduces environmental pollution and improves system stability and flexibility, making it an effective means of improving the economic, environmental, and sustainable nature of ammonia recovery systems.

[0057] The utility model uses the following process:

[0058] 1. Ammonia enters the system:

[0059] Preliminary waste gas (containing ammonia) enters the system through a pipeline. At this stage, the concentration of ammonia is high, possibly from industrial production processes or waste gas emissions.

[0060] 2. Primary recovery tank 2 processing:

[0061] Ammonia first enters the primary recovery tank 2. At this stage, the high concentration of ammonia in the gas is preliminarily adsorbed, and the adsorbent works in a high concentration of ammonia environment to adsorb most of the ammonia. The adsorbent in the primary recovery tank 2 quickly adsorbs and captures ammonia.

[0062] The main role of this stage is to reduce the concentration of ammonia in the gas and reduce the burden on subsequent equipment.

[0063] 3. Condensation processing:

[0064] The main recovery tank 1 is connected to the condensation tank 3, and the waste gas flows from the primary recovery tank 2 to the main recovery tank 1, with some ammonia being further condensed at this stage.

[0065] The condensation tank 3 condenses the unadsorbed ammonia into a liquid state through cooling and liquefaction. By liquefying, the ammonia is concentrated, improving its recovery efficiency. After condensation, the remaining gas is further processed by the main recovery tank 1.

[0066] 4. Secondary recovery process:

[0067] After condensation, some ammonia still exists in gaseous form. At this time, the circulating motor 9 introduces the ammonia in the condensation tank 3 into the main recovery tank 1 through the circulating pipeline 7, forming secondary recovery.

[0068] Secondary recovery effectively captures ammonia gas that was not fully recovered during the primary recovery process. Through the circulation system, the gas is redirected back to the main recovery tank 1 for adsorption and recovery of residual ammonia gas.

[0069] 5. Adsorption and Concentration:

[0070] In the main recovery tank 1, the gas after preliminary treatment and condensation continues to contact with the adsorbent, which can effectively adsorb at a lower concentration of ammonia gas.

[0071] The adsorption effect at this stage is uniform, and the adsorbent can maintain high efficiency for a long time, without premature saturation caused by high concentration of ammonia gas.

[0072] 6. Gas Outlet and Discharge:

[0073] After the gas is treated in the main recovery tank 1, most of the ammonia gas has been adsorbed or condensed, and the remaining gas is discharged through the gas outlet pipe 8. At this time, the ammonia concentration in the gas has been greatly reduced, meeting the discharge standards.

[0074] Valves are installed on the gas outlet pipe 8 to ensure the control and adjustment of the discharged gas, preventing accidental leakage or incomplete treatment of exhaust gas.

[0075] 7. Observation and Monitoring:

[0076] The observation window 12 allows workers to monitor the system's running state in real time, and timely detect whether the equipment is working normally.

[0077] Through the sensors installed on the equipment and the intelligent control system, the concentration of exhaust gas, recovery efficiency, adsorbent state, etc. can be monitored in real time, and the working state of the system is automatically adjusted to optimize the recovery efficiency.

[0078] 8. Maintenance and Regeneration:

[0079] After a long time of use, the adsorbent may reach a certain degree of saturation and needs regular regeneration treatment. The system design allows regular cleaning or regeneration of the adsorbent to restore its adsorption capacity and ensure the continuous and efficient operation of the system.

[0080] Regular inspection and maintenance, including cleaning and inspection of the condensation tank 3, circulation motor 9, and adsorption tower, ensure the stability and reliability of the system.
