Abstract
Description
Technical Field
[0001] This invention relates to the field of nuclear power filtration technology, and in particular to a humidity control system and adsorption device for an adsorption apparatus. Background Technology
[0002] The main airborne radioactive effluents from nuclear power plants include radioactive aerosols, inert gases, and iodine. Among these, gaseous radioactive iodine poses the greatest threat to personnel. Although its concentration is extremely low, the human thyroid gland has a strong ability to adsorb radioactive iodine. Therefore, it is essential to treat the air containing radioactive elements inside the power plant. Furthermore, to minimize the circulation of radioactive products within the plant or their release into the environment, ventilation systems should be installed in potentially contaminated rooms. The most common method for ventilation systems in nuclear power plants is to use iodine adsorbers with activated carbon as the adsorbent to remove radioactive iodine.
[0003] However, the adsorption capacity of activated carbon is affected by the experimental environment. For example, organic compounds such as benzene and methyl iodine, as well as water vapor, exhibit a certain degree of adsorption competition on activated carbon. When the relative humidity is low (10-30%), the competition is not significant; however, when the relative humidity is ≥50%, the presence of water vapor will have a significant inhibitory effect on the adsorption of benzene. According to technical requirements, the storage humidity of activated carbon should be below 70%. However, in summer, the actual humidity on-site is 80-90%, and the large amount of water vapor in the environment will reduce the adsorption effect of activated carbon. Summary of the Invention

[0011] Optionally, the first humidity condition is whether the relative humidity after dehumidification by the second dehumidification module alone meets the humidity requirements of the adsorption device.
[0012] Optionally, whether the relative humidity after dehumidification by the second dehumidification module alone meets the humidity requirements of the adsorption device includes: if it is greater than the first preset humidity, then it is determined that the relative humidity after dehumidification by the second dehumidification module alone cannot meet the humidity requirements of the adsorption device; otherwise, it is determined that the relative humidity after dehumidification by the second dehumidification module alone can meet the humidity requirements of the adsorption device.

[0028] Figure 1 This is a schematic diagram illustrating the principle structure of a humidity control system for an adsorption device provided in an embodiment of the present invention. (Reference) Figure 1The humidity control system of the adsorption device includes: a first hygrometer 10, a second hygrometer 20, a third hygrometer 30, a first dehumidification module 40, and a second dehumidification module 50; wherein, the first hygrometer 10 is electrically connected to the first dehumidification module 40, the second hygrometer 20 is electrically connected to the second dehumidification module 50, and the third hygrometer 30 is electrically connected to the adsorption device 60; the first air inlet A1 of the first dehumidification module 40 is connected to the first hygrometer 10, the air outlet A0 of the first dehumidification module 40 is connected to the air inlet B1 of the second dehumidification module 50, the second hygrometer 20 is connected to the air inlet B1 of the second dehumidification module 50, and the air outlet B0 of the second dehumidification module 50 is connected to the air inlet C1 of the adsorption device 60. The first hygrometer 10 monitors the relative humidity of the air entering the first air inlet A1 of the first dehumidification module 40, and controls the first dehumidification module 40 to shut down when the relative humidity of the air entering the first air inlet A1 of the first dehumidification module 40 meets a first humidity condition, and controls the first dehumidification module 40 to start when the relative humidity of the air entering the first air inlet A1 of the first dehumidification module 40 does not meet the first humidity condition; the second hygrometer 20 monitors the relative humidity of the air entering the second dehumidification module 50 at the air inlet B1, and controls the first dehumidification module 40 to start when the relative humidity of the air entering the second dehumidification module 50 at the air inlet B1 meets the first humidity condition. When the second humidity condition is met, the second dehumidification module 50 is controlled to close; when the relative humidity of the air intake at the air intake end B1 of the second dehumidification module 50 does not meet the second humidity condition, the second dehumidification module 50 is controlled to start. The third hygrometer 30 is used to monitor the relative humidity of the air intake at the air intake end C1 of the adsorption device 60, and controls the air intake passage of the adsorption device 60 to open when the relative humidity of the air intake at the air intake end C1 of the adsorption device 60 meets the second humidity condition, and controls the air intake passage of the adsorption device 60 to close when the relative humidity of the air intake at the air intake end C1 of the adsorption device 60 does not meet the second humidity condition.
[0029] The first hygrometer 10 can be used to monitor the relative humidity of the air entering the first dehumidification module 40 at its first inlet A1 at the current temperature, and can also be used to automatically control the start and stop of the first dehumidification module 40. The second hygrometer 20 can be used to monitor the relative humidity of the air entering the second dehumidification module 50 at its inlet B1 at the current temperature, and can also be used to automatically control the start and stop of the second dehumidification module 50. The third hygrometer 30 can be used to monitor the relative humidity of the air entering the adsorption device 60 at its inlet C1 at the current temperature, and can also be used to automatically control the opening and closing of the air intake passage of the adsorption device 60. Therefore, by studying the effect of relative humidity on the activated carbon adsorption device under different temperature conditions, the start and stop of the first and second dehumidification modules are automatically controlled under different conditions. By using three hygrometers in the system process to monitor the overall humidity of the system, intelligent adjustment of the intake humidity is achieved, and the overall energy consumption of the system is reduced.
[0030] The air intake at the first air intake end A1 of the first dehumidification module 40 is the initial air intake. The air intake at the air intake end B1 of the second dehumidification module 50 can come from the gas that has passed through the first dehumidification module 40 and / or the gas that has not passed through the first dehumidification module 40 (i.e., the initial air intake).
[0031] The adsorption device 60 can be an activated carbon adsorber.
[0032] In the technical solution of this embodiment, the implementation process of the humidity control system of the adsorption device is as follows: (Refer to...) Figure 1 First, the first hygrometer 10 monitors the humidity of the air entering through the first intake port A1 of the first dehumidification module 40 and determines whether the relative humidity of the air meets the first humidity condition. If the first humidity condition is met, the first dehumidification module 40 is shut off, allowing the initial air to enter the next stage without being dehumidified by the first dehumidification module 40. If the first humidity condition is not met, the first dehumidification module 40 is activated, allowing the initial air to be dehumidified by the first dehumidification module 40 before entering the next stage. The second hygrometer 20 monitors the relative humidity of the air entering through the intake port B1 of the second dehumidification module 50 and determines whether the relative humidity of the air meets the second humidity condition. If the second humidity condition is met, the second dehumidification module 50 is shut off, allowing the air to enter the next stage without being dehumidified by the second dehumidification module 50. If the second humidity condition is not met, the second dehumidification module 50 is activated, allowing the air to be dehumidified by the second dehumidification module 50 before entering the next stage. The third hygrometer 30 monitors the humidity of the air entering the adsorption device 60 at the inlet C1 and determines whether the relative humidity of the incoming air meets the second humidity condition. If the second humidity condition is met, the air inlet passage of the adsorption device 60 is opened, allowing the incoming air to directly enter the subsequent processing stage. If the second humidity condition is not met, the air inlet passage of the adsorption device 60 is closed, allowing the incoming air to undergo further dehumidification treatment. Therefore, by setting up the first, second, and third hygrometers, the humidity of the gas entering the adsorption device is automatically monitored throughout the entire process. Furthermore, by setting up the first and second dehumidification modules, the start and stop of the first and / or second dehumidification modules are automatically adjusted according to different incoming air humidity levels, thus enabling overall humidity monitoring of the system and achieving intelligent adjustment of the incoming air humidity. This reduces the overall energy consumption of the system, eliminates the impact of humidity issues on the adsorption efficiency of the activated carbon adsorption device, and ensures the adsorption effect of the adsorption device. Through full-process humidity monitoring, the humidity of the incoming air to the adsorption device is guaranteed to meet the standards.
[0033] The technical solution of this embodiment provides a humidity control system for an adsorption device. This system includes a first hygrometer, a second hygrometer, a third hygrometer, a first dehumidification module, and a second dehumidification module. The first hygrometer is electrically connected to the first dehumidification module, the second hygrometer is electrically connected to the second dehumidification module, and the third hygrometer is electrically connected to the adsorption device. The first air inlet of the first dehumidification module is connected to the first hygrometer, the air outlet of the first dehumidification module is connected to the air inlet of the second dehumidification module, the second hygrometer is connected to the air inlet of the second dehumidification module, and the air outlet of the second dehumidification module is connected to the air inlet of the adsorption device. The first hygrometer monitors the relative humidity of the air entering the first air inlet of the first dehumidification module and determines the relative humidity when the relative humidity of the air entering the first air inlet of the first dehumidification module reaches a certain level. The system controls the first dehumidification module to shut down when the relative humidity at the first air inlet of the first dehumidification module meets the first humidity condition, and controls it to start when the relative humidity at the first air inlet of the first dehumidification module does not meet the first humidity condition. A second hygrometer monitors the relative humidity at the air inlet of the second dehumidification module, and controls it to shut down when the relative humidity at the air inlet of the second dehumidification module meets the second humidity condition, and controls it to start when the relative humidity at the air inlet of the second dehumidification module does not meet the second humidity condition. A third hygrometer monitors the relative humidity at the air inlet of the adsorption device, and controls the air inlet passage of the adsorption device to open when the relative humidity at the air inlet of the adsorption device meets the second humidity condition, and controls it to close when the relative humidity at the air inlet of the adsorption device does not meet the second humidity condition. Therefore, this system can control the humidity of the adsorption device, thereby ensuring its adsorption effect.
[0034] Optionally, the first humidity condition is whether the relative humidity after dehumidification by the second dehumidification module alone meets the humidity requirements of the adsorption device.
[0035] The specific humidity value or range required for the adsorption device can be set according to the actual situation, and no specific limit is made here.
[0036] Specifically, the first hygrometer 10 monitors the relative humidity of the incoming air at the first air inlet A1 of the first dehumidification module 40. It determines whether the relative humidity of the incoming air, after only being dehumidified by the second dehumidification module, meets the humidity requirements of the adsorption device 60. If it does, the first dehumidification module 40 is shut off, allowing the initial incoming air to directly enter the next stage without being processed by the first dehumidification module 40. If it does not meet the requirements, the first dehumidification module 40 is activated, allowing the initial gas to be dehumidified by the first dehumidification module 40 before entering the next stage.
[0037] Optionally, whether the relative humidity after dehumidification by the second dehumidification module alone meets the humidity requirements of the adsorption device includes: if it is greater than the first preset humidity, then it is determined that the relative humidity after dehumidification by the second dehumidification module alone cannot meet the humidity requirements of the adsorption device; otherwise, it is determined that the relative humidity after dehumidification by the second dehumidification module alone can meet the humidity requirements of the adsorption device.
[0038] The first preset humidity can be a specific humidity value or a humidity range. Its setting is derived from the conversion of the relative moisture content of the air at different temperatures and the comprehensive calculation of the dehumidification effects of the first and second dehumidification modules. It can be set according to the actual situation and is not specifically limited here.
[0039] The first preset humidity can be entered in advance.
[0040] Specifically, the first hygrometer 10 monitors the relative humidity of the incoming air at the first air inlet A1 of the first dehumidification module 40 at the current temperature. It determines whether the relative humidity of the incoming air, after only being dehumidified by the second dehumidification module, meets the humidity requirements of the adsorption device 60. If it does, the first dehumidification module 40 is shut off, allowing the initial incoming air to directly enter the next stage without being dehumidified by the first dehumidification module 40. If it does not meet the requirements, the first dehumidification module 40 is activated, allowing the initial gas to be dehumidified by the first dehumidification module 40 before entering the next stage.
[0041] Optionally, the second humidity condition is whether the relative humidity meets the humidity requirements of the adsorption device.
[0042] Specifically, the second hygrometer 20 monitors the relative humidity of the air entering through the inlet B1 of the second dehumidification module 50 at the current temperature. It then determines whether the relative humidity meets the humidity requirements of the adsorption device. If it does, the second dehumidification module 50 is shut off, allowing the gas to bypass dehumidification and proceed directly to the next stage. If the requirements are not met, the second dehumidification module 50 is activated, allowing the gas to pass through it for dehumidification before entering the next stage.
[0043] Similarly, the third hygrometer 30 monitors the relative humidity of the air entering the adsorption device 60 at the current temperature through the air inlet C1. It then determines whether the relative humidity of the air entering the adsorption device 60 meets its humidity requirements. If it does, the air inlet passage of the adsorption device 60 is opened, allowing the air to directly enter the subsequent processing stage. If it does not meet the requirements, the air inlet passage of the adsorption device 60 is closed, requiring the air to undergo further dehumidification treatment.
[0044] The humidity requirement for the adsorption device is set as the second preset humidity, which can be a specific humidity value or a humidity range, etc. The setting is derived from the experiment of activated carbon adsorbing radioactive methyl iodine under different temperature and humidity conditions. The specific setting can be set according to the actual situation, and no specific limitation is made here.
[0045] The second preset humidity can be entered in advance. The first preset humidity and the second preset humidity are different.
[0046] Optionally, the first dehumidification module is a dehumidifier.
[0047] Among them, the dehumidifier uses the condensation effect of cooling to pre-extract some of the moisture in the gas, thereby reducing the absolute humidity of the gas.
[0048] Optionally, the second dehumidification module is an electric heater.
[0049] The electric heater increases the relative humidity of the gas by heating it within a certain range.
[0050] Figure 2 This is a schematic block diagram of the humidity control system of another adsorption device provided in an embodiment of the present invention. Optionally, based on the above embodiments, refer to... Figure 2 The second air inlet A2 of the first dehumidification module 40 is connected to the air inlet C1 of the adsorption device 60.
[0051] Specifically, the third hygrometer 30 monitors the relative humidity of the air entering the adsorption device 60 at the inlet C1 at the current temperature. It then determines whether this relative humidity meets the humidity requirements of the adsorption device 60. If it does, the air inlet passage of the adsorption device 60 is opened, allowing the air to directly enter the subsequent processing stage. If it does not meet the requirements, the air inlet passage of the adsorption device 60 is closed. Since the air inlet C1 of the adsorption device 60 is also connected to the second air inlet A2 of the first dehumidification module 40, the gas returns directly to the second air inlet A2 of the first dehumidification module 40 for dehumidification after the air inlet passage of the adsorption device is closed. The second hygrometer 20 monitors the humidity of the gas after dehumidification by the first dehumidification module 40 and determines whether its humidity meets the second humidity condition. If it does, the second dehumidification module 50 is closed, allowing the gas to directly enter the next stage without passing through the second dehumidification module 50. If it does not meet the requirements, the second dehumidification module 50 is activated, allowing the gas to be dehumidified by the second dehumidification module 50 before entering the next stage. This process is repeated until the relative humidity of the gas entering the inlet C1 of the adsorption device 60 meets the humidity requirements of the adsorption device 60. This further improves the accuracy and effectiveness of gas humidity monitoring, enhances intelligent adjustment of inlet humidity, and reduces the overall energy consumption of the system.
[0052] refer to Figure 2The humidity control system of the adsorption device also includes a pre-high-efficiency filter 101, a high-efficiency particulate filter assembly 102, and a post-high-efficiency filter assembly 103. The pre-high-efficiency filter 101 protects the high-efficiency particulate filter assembly 102 from coarse particulate contamination, extending its service life. The high-efficiency particulate filter assembly 102 removes suspended radioactive pollutants from the air before they enter the activated carbon adsorption device. The post-high-efficiency filter assembly 103 captures activated carbon particles lost from the activated carbon adsorption device.
[0053] In the technical solution of this embodiment, the implementation process of the humidity control system of the adsorption device is as follows: (Refer to...) Figure 2First, the first hygrometer 10 monitors the humidity of the air entering through the first inlet A1 of the first dehumidification module 40 and determines whether the relative humidity of the air meets the first humidity condition. If the first humidity condition is met, the first dehumidification module 40 is shut off, allowing the initial air to enter the next stage directly without being dehumidified by the first dehumidification module 40. If the first humidity condition is not met, the first dehumidification module 40 is activated, allowing the initial gas to be dehumidified by the first dehumidification module 40 before entering the next stage. The second hygrometer 20 monitors the relative humidity of the air entering through the inlet B1 of the second dehumidification module 50 and determines whether the relative humidity of the air meets the second humidity condition. If the second humidity condition is met, the second dehumidification module 50 is shut off, allowing the gas to pass through the pre-high-efficiency filter 101 and the high-efficiency particulate filter group 102 sequentially before entering the inlet C1 of the adsorption device 60 without being dehumidified by the second dehumidification module 50. If the second humidity condition is not met, the second dehumidification module 50 is activated, allowing the gas to be dehumidified by the second dehumidification module 50 and then sequentially pass through the pre-high-efficiency filter 101 and the high-efficiency particulate filter group 102 before entering the air inlet C1 of the adsorption device 60. The third hygrometer 30 monitors the humidity of the air entering the adsorption device 60 at the air inlet C1 and determines whether the relative humidity of the air entering the adsorption device meets the second humidity condition. If the second humidity condition is met, the air inlet passage of the adsorption device 60 is opened, allowing the air to directly enter the adsorption device for subsequent processing. If the second humidity condition is not met, the air inlet passage of the adsorption device 60 is closed. Since the air inlet C1 of the adsorption device 60 is also connected to the second air inlet A2 of the first dehumidification module 40, the gas returns directly to the second air inlet A2 of the first dehumidification module 40 for dehumidification after the air inlet passage of the adsorption device is closed. The second hygrometer 20 monitors the humidity of the gas after dehumidification by the first dehumidification module 40 and determines whether the humidity meets the second humidity condition. If it does, the second dehumidification module 50 is closed, allowing the gas to enter the next stage directly without passing through the second dehumidification module 50. If it does not meet the condition, the second dehumidification module 50 is activated, allowing the gas to be dehumidified by the second dehumidification module 50 before entering the next stage. This cycle repeats until the relative humidity of the gas entering the air inlet C1 of the adsorption device 60 meets the humidity requirement of the adsorption device 60. Therefore, by setting up a first hygrometer, a second hygrometer, and a third hygrometer, the humidity of the gas entering the adsorption device can be automatically monitored throughout the entire process. Furthermore, by setting up a first dehumidification module and a second dehumidification module, the start and stop of the first and / or second dehumidification modules are automatically adjusted according to different inlet air humidity levels. This allows for overall monitoring of the system's humidity, achieving intelligent adjustment of inlet air humidity, reducing the overall energy consumption of the system, eliminating the impact of humidity on the adsorption efficiency of the activated carbon adsorption device, and thus ensuring the adsorption effect of the adsorption device.
[0054] Figure 3This is a schematic block diagram of the humidity control system of another adsorption device provided in an embodiment of the present invention. Optionally, based on the above embodiments, refer to... Figure 3 The humidity control system of the adsorption device also includes a humidity adjustment module 70, which is connected to the adsorption device 60 and is used to adjust the relative humidity of the gas outlet C0 of the adsorption device 60.
[0055] By setting up a first, second, and third hygrometer, the humidity of the gas entering through the air inlet can be monitored and judged. Gas with excessively high humidity must be dehumidified in advance, and subsequent monitoring should be performed in real time. Gas with low humidity does not require dehumidification. Furthermore, the humidity of the gas at the outlet should also be appropriately humidified; therefore, a humidity control module 70 is provided. This humidity control module 70 is used to humidify and replenish water for the treated gas with low humidity, preventing the outlet gas from making the working environment too dry.
[0056] The humidity control module 70 can be a humidity regulator.
[0057] Optionally, the humidity control system of the adsorption device further includes a condensate collection device 80, which is connected to a second air inlet A2 that is respectively connected to the humidity adjustment module 70 and the first dehumidification module 40.
[0058] The condensate collection device 80 can be used to collect the water condensed during the dehumidification process of the dehumidifier and can be used as supplementary water for the final outlet air humidity adjustment. This achieves resource recycling and reuse, improves the humidity of the outlet air, optimizes the ambient air quality, and realizes the circular use of resources.
[0059] In the technical solution of this embodiment, the implementation process of the humidity control system of the adsorption device is as follows: (Refer to...) Figure 3First, the first hygrometer 10 monitors the humidity of the air entering through the first inlet A1 of the first dehumidification module 40 and determines whether the relative humidity of the air meets the first humidity condition. If the first humidity condition is met, the first dehumidification module 40 is shut off, allowing the initial air to enter the next stage directly without being dehumidified by the first dehumidification module 40. If the first humidity condition is not met, the first dehumidification module 40 is activated, allowing the initial gas to be dehumidified by the first dehumidification module 40 before entering the next stage. The condensate generated during the dehumidification process of the first dehumidification module 40 can be collected by a condensate collection device and used as supplementary water for the humidity adjustment module 70. The second hygrometer 20 monitors the relative humidity of the air entering through the inlet B1 of the second dehumidification module 50 and determines whether the relative humidity of the air meets the second humidity condition. If the second humidity condition is met, the second dehumidification module 50 is shut off, allowing the gas to pass through the pre-high-efficiency filter 101 and the high-efficiency particulate filter group 102 sequentially without being dehumidified by the second dehumidification module 50 before entering the inlet C1 of the adsorption device 60. If the second humidity condition is not met, the second dehumidification module 50 is activated, allowing the gas to be dehumidified by the second dehumidification module 50 and then sequentially pass through the pre-high-efficiency filter 101 and the high-efficiency particulate filter group 102 before entering the air inlet C1 of the adsorption device 60. The third hygrometer 30 monitors the humidity of the air entering the adsorption device 60 at the air inlet C1 and determines whether the relative humidity of the air entering the adsorption device 60 meets the second humidity condition. If the second humidity condition is met, the air inlet passage of the adsorption device 60 is opened, allowing the air to directly enter the adsorption device 60 for processing before entering the post-high-efficiency filter group 103 for filtration. After filtration, the air is then regulated by the humidity adjustment module 70 before being discharged. If the second humidity condition is not met, the air inlet passage of the adsorption device 60 is closed. Since the air inlet C1 of the adsorption device 60 is also connected to the second air inlet A2 of the first dehumidification module 40, the gas returns directly to the second air inlet A2 of the first dehumidification module 40 for dehumidification after the air inlet passage of the adsorption device 60 is closed. The second hygrometer 20 monitors the humidity of the gas after dehumidification by the first dehumidification module 40 and determines whether the humidity meets the second humidity condition. If it does, the second dehumidification module 50 is closed, allowing the gas to enter the next stage directly without passing through the second dehumidification module 50. If it does not meet the condition, the second dehumidification module 50 is activated, allowing the gas to be dehumidified by the second dehumidification module 50 before entering the next stage. This cycle repeats until the relative humidity of the gas entering the air inlet C1 of the adsorption device 60 meets the humidity requirement of the adsorption device 60.Therefore, by setting up a first hygrometer, a second hygrometer, and a third hygrometer, the humidity of the gas entering the adsorption device can be automatically monitored throughout the entire process. Furthermore, by setting up a first dehumidification module and a second dehumidification module, the start and stop of the first and / or second dehumidification modules are automatically adjusted according to different inlet air humidity levels. This allows for overall monitoring of the system's humidity, achieving intelligent adjustment of inlet air humidity, reducing the overall energy consumption of the system, eliminating the impact of humidity on the adsorption efficiency of the activated carbon adsorption device, and thus ensuring the adsorption effect of the adsorption device.
